Viewlight NW 64th St. Vioss NW 66th St. Vioss security NW 66th St. Neuroregulation SW 56th St. Efficient Laboratories NW 64th St. HealthPath Partners Coral Way Results A total of 81 patients were enrolled, of which 72 patients completed the first 3 cycles of chemotherapy followed by prescribed RT.
Median age was 67 years range: Of the chemotherapy cycles administered, there were 11 2. Objective We wanted to determine whether transcatheter Ethiodol-based capillary embolization in combination with carboplatin could improve the efficiency of a 1: Materials and Methods The right kidney in 34 New Zealand white rabbits were inoculated with fresh VX-2 tumor fragments.
The animals were followed for up to 3-weeks. The treated kidneys were evaluated angiographically and macroscopically. The kidneys that showed successful embolization macroscopically were entirely cut into serial sections, and these were examined microscopically. Histologically, the kidneys were evaluated on the basis of the residual tumor found in the serial sections. Kidneys from Groups demonstrated macroscopically successful embolization with histologically proven complete renal parenchyma infarction; however, some residual tumor was evident in all but one animal.
Conclusion None of the Ethiodol-based modalities combined with locoregional carboplatin were more efficacious for tumor ablation than EEM alone. Combination therapy of canine osteosarcoma with canine bone marrow stem cells, bone morphogenetic protein and carboplatin in an in vivo model.
Osteosarcoma OSA is the most common malignant bone cancer in children and dogs. The therapeutic protocols adopted for dogs and humans are very similar, involving surgical options such as amputation. Besides surgical options, radiotherapy and chemotherapy also are adopted.
However, hematologic, gastrointestinal and renal toxicity may occur because of chemotherapy treatments. Recent study clearly showed that mesenchymal stem cells MSCs combined with recombinant human bone morphogenetic protein rhBMP-2 may be associated with decreases of the tumorigenic potential of canine OSA. Flow cytometry and PCR for markers involved in tumour suppression pathways were analysed. Results showed that the combination of MSCs and rhBMP-2 reduced tumour mass and infiltration of neoplastic cells in tissues more efficiently than carboplatin alone.
Thus it was demonstrated that the use of rhBMP-2 and MSCs, in combination with conventional antineoplastic, may be an efficient treatment strategy. HD was started at a point in time one hour after the completion of each CBDCA administration, and performed for 5 hours in each course. Blood samples were collected during the first 3 courses of chemotherapy to measure the plasma concentration of free-platinum.
The o-AUC in the first course was lower than that in the second course. Partial response was achieved after two courses of the CBDCA and paclitaxel combination chemotherapy , with adverse events of Grade 3 neutropenia and Grade 3 peripheral neuropathy observed in each course after the second course of chemotherapy. Convection enhanced delivery of carboplatin in combination with radiotherapy for the treatment of brain tumors. The purpose of this study was to further evaluate the therapeutic efficacy of convection enhanced delivery CED of carboplatin in combination with radiotherapy for treatment of the F98 rat glioma.
Tumor cells were implanted stereotactically into the brains of syngeneic Fischer rats, and 13 or 17 d. Other groups of rats received either carboplatin or X-irradiation alone. Rats bearing small tumors, treated with carboplatin and X-irradiation, had a mean survival time MST of There was no microscopic evidence of residual tumor in the brains of all long-term survivors.
Not surprisingly, rats with large tumors had much shorter MSTs. Only modest increases in MSTs were observed in animals that received either oral administration or CED of temozolomide plus X-irradiation The present survival data, and those previously reported by us, are among the best ever obtained with the F98 glioma model. Initially, they could provide a platform for a Phase I clinical trial to evaluate the safety and potential therapeutic efficacy of CED of carboplatin in patients with recurrent glioblastomas, and ultimately a Phase II trial of carboplatin in combination with radiation therapy.
Comparison of carboplatin and doxorubicin-based chemotherapy protocols in dogs after amputation for treatment of appendicular osteosarcoma. Many chemotherapy protocols have been reported for treatment of canine appendicular osteosarcoma OSA , but outcome comparisons in a single population are lacking.
To evaluate the effects of protocol and dose intensity DI on treatment outcomes for carboplatin and doxorubicin-based chemotherapy protocols. Four hundred and seventy dogs with appendicular OSA. A retrospective cohort study was performed comprising consecutive dogs treated with amputation followed by 1 of 5 chemotherapy protocols: Adverse events AE and DI were evaluated.
Kaplan-Meier survival curves and Cox proportional hazards regression were used to compare disease-free interval DFI and survival time ST among protocols. DI was not associated with development of metastases or death. After adjustment for baseline characteristics and prognostic factors, none of the protocols provided a significant reduction in risk of development of metastases or death.
Although choice of protocol did not result in significant differences in DFI or ST, the CARBO6 protocol resulted in a lower proportion of dogs experiencing AEs, which could be advantageous in maintaining high quality of life during treatment.
DI was not a prognostic indicator in this study. Phase I study of carboplatin combined with pemetrexed for elderly patients with advanced non-squamous non-small cell lung cancer. Dose escalation was decided according to whether dose-limiting toxicity occurred in the first cycle of chemotherapy.
A total of 20 patients 6 at Level 1, 14 at Level 2 were enrolled. Among a total of 14 patients in Level 2, only 1 patient experienced dose-limiting toxicity: Grade 3 febrile neutropenia and urticaria. The major toxicities were neutropenia, thrombocytopenia and anemia. Liver dysfunction, fatigue and anorexia were also common, but generally manageable. The median progression-free survival period was 4. A phase I report of paclitaxel dose escalation combined with a fixed dose of carboplatin in the treatment of head and neck carcinoma.
New combined modality treatment strategies are being tested to improve survival. New chemotherapy combinations are being developed and administered simultaneously with, or sequenced with, radiation and surgery.
This article reports the Phase I results of administering paclitaxel and carboplatin preoperatively. The authors' objective was to develop an outpatient chemotherapy that would downstage tumors and allow organ preservation with equal or improved survival as compared with standard therapy. All patients had lesions that were measurable in perpendicular planes. Premedication was used to avoid acute hypersensitivity reactions. Carboplatin was administered intravenously over 1 hour at a constant dose calculated with the Calvert formula area under the curve, 7.
Other observed adverse effects included pruritus, myalgia, arthralgia, alopecia, nausea, and vomiting. Phase II studies of this combination are warranted in the treatment of these carcinomas. A phase I and pharmacologic study of sequences of the proteasome inhibitor, bortezomib PS, Velcade , in combination with paclitaxel and carboplatin in patients with advanced malignancies. Bortezomib, a selective inhibitor of the 20S proteasome with activity in a variety of cancers, exhibits sequence-dependent synergistic cytotoxicity with taxanes and platinum agents.
Two different treatment schedules of bortezomib in combination with paclitaxel and carboplatin were tested in this phase I study to evaluate the effects of scheduling on toxicities, pharmacodynamics and clinical activity.
Patients with advanced malignancies were alternately assigned to receive schedule A paclitaxel and carboplatin IV d1 followed by bortezomib IV d2, d5, d8 or schedule B bortezomib IV d1, d4, d8 followed by paclitaxel and carboplatin IV d2 on a day cycle. Fifty-three patients A 25, B 28 were treated with a median of 3 cycles range for schedule A and 3.
Non-hematologic treatment related adverse events were fairly mild primarily grades 1 and 2. The maximum tolerated dose and the recommended doses for future phase II trials are bortezomib 1. Similar proteasome inhibition was achieved at MTD for both schedules. Administration of sequential bortezomib followed by chemotherapy schedule B was well tolerated and associated with an encouraging number of objective responses in this small group of patients.
Further studies with this administration schedule are warranted. Usefulness of antiemetic therapy with aprepitant, palonosetron, and dexamethasone for lung cancer patients on cisplatin-based or carboplatin -based chemotherapy. The purpose of the study is to investigate the usefulness of the triplet regimen comprising aprepitant, palonosetron, and dexamethasone in patients treated with highly emetogenic chemotherapy HEC and moderately emetogenic chemotherapy MEC. Patients with lung cancer aged The antiemetic regimen for both types of chemotherapy consisted of aprepitant, palonosetron, and dexamethasone based on the May guidelines prepared by the Japan Society of Clinical Oncology.
The incidence of chemotherapy -induced nausea and vomiting CINV and the use of salvage treatment were assessed. The primary endpoints were the percentage of patients with a complete response CR: Most of the patients could ingest food throughout the entire period after chemotherapy. Assessment of various risk factors for acute and delayed CINV gender, age, prior vomiting due to antineoplastic therapy, prior experience of motion sickness, and history of drinking revealed no significant influence of these factors on the CR rate for the entire period in patients receiving either carboplatin -based or cisplatin-based chemotherapy.
The present triple therapy can be recommended for supporting both carboplatin -based and cisplatin-based chemotherapy regimens. The effects of taurolidine alone and in combination with doxorubicin or carboplatin in canine osteosarcoma in vitro.
The disease usually arises in the appendicular skeleton and metastasizes to the lung. Dogs with localized appendicular disease benefit from limb amputation and chemotherapy but most die within months despite these treatments. Taurolidine, a derivative of taurine, has anti-tumor and anti-angiogenic effects against a variety of cancers. The following in vitro studies tested taurolidine as a candidate for adjuvant therapy for canine OS.
Tests for p53 protein status and caspase activity were used to elucidate mechanisms of taurolidine-induced cell death. Taurolidine was cytotoxic to osteosarcoma cells and increased the toxicity of doxorubicin and carboplatin in vitro.
Taurolidine cytotoxicity appeared caspase-dependent in one cell line; with apparent mutant p53 protein. This cell line was the most sensitive to single agent taurolidine treatment and had a taurolidine-dependent reduction in accumulated p53 protein suggesting taurolidine's effects may depend on the functional status of p53 in canine OS.
Taurolidine's cytotoxic effect appears dependent on cell specific factors which may be explained, in part, by the functional status of p Taurolidine initiates apoptosis in canine OS cells and this occurs to a greater extent at lower concentrations. Mechanisms of cell death induced by higher concentrations were not elucidated here. Taurolidine combined with doxorubicin or carboplatin can increase the toxicity of these chemotherapy drugs and warrants further investigation in dogs with osteosarcoma.
Patient demographics were not significantly different between both groups. Nine toceranib-treated and 11 control dogs completed the study without evidence of metastatic disease 1-year following amputation. Toceranib-treated dogs experienced more episodes of diarrhea, neutropenia and weight loss than control dogs, although these toxicities were low-grade and typically resolved with supportive care.
The addition of toceranib to metronomic piroxicam. Characterization and carboplatin loaded chitosan nanoparticles for the chemotherapy against breast cancer in vitro studies. Aim of the studies to synthesized chitosan nanoparticles by an ionic interaction procedure. The average particle size of chitosan and carboplatin nanoparticles was found to be The maximum entrapment of carboplatin in nanoparticles was a spherical shape with a positive charge.
The nanocarboplatin was better blood compatibility as compared to chitosan nanoparticles. Finally, the cytotoxic effects of the carboplatin loaded chitosan nanoparticles were tested in-vitro against breast cancer MCF-7 cell lines.
Our studies showed that the chitosan nanoparticles could be used as a promising candidate for drug delivery for the therapeutic treatment of breast cancer. Metronomic chemotherapy has translated into favorable toxicity profile and capable of delaying tumor progression. Despite its promise, conventional injectable chemotherapeutics are not meaningful to use as metronomic due to the necessity of frequent administration for personalized therapy in long-term cancer treatments.
This study aims to exploit the benefits of the oral application of carboplatin as metronomic therapy for non-small cell lung cancer NSCLC. We developed an orally active carboplatin by physical complexation with a deoxycholic acid DOCA.
The dose dependent antitumor effects of oral carboplatin were evaluated in SCC7 and A tumor xenograft mice. Hyperthermic intraperitoneal chemotherapy HIPEC involves the continuous heating and circulation of chemotherapy throughout the abdominal cavity in an attempt to enhance cytotoxicity.
Despite the potential of this chemotherapy procedure, there are scant anatomical temperature distribution studies reporting on this therapeutic process. We prospectively evaluated the temperature of select anatomical e. The lowest observed mean composite temperature was During the various time intervals we also ascertained that the lowest composite temperature was We also discerned that uniform temperature distribution throughout the abdominal cavity was facilitated when the abdomen was both maximally distended with fluid and a high flow rate was maintained.
To evaluate the efficacy of prolonged intracerebral i. Seven days after stereotactic implantation of F98 glioma cells into the brains of Fischer rats, carboplatin was administrated i. Rats were treated at the European Synchrotron Radiation Facility with a single Gy X-ray dose, either given alone or 24 h after administration of carboplatin. Our data demonstrate that i. They provide strong support for the approach of concomitantly administering chemo- and radiotherapy for the treatment of brain tumors.
A phase I trial was conducted to determine the maximally tolerated dose MTD of afatinib in combination with carboplatin and paclitaxel as induction chemotherapy IC. Afatinib was started at a dose of 20mg daily and dose escalated using a modified Fibonacci design. Seven of nine patients completed afatinib lead-in and IC.
Five patients had partial response and two patients had stable disease after IC. Dose level 1 afatinib 20mg was well tolerated with one grade 3 ALT elevation and one grade 4 neutropenia toxicities. However, dose level 2 afatinib 30mg was not well tolerated with nine grade 3 pneumonia, abdominal pain, diarrhea, pancytopenia, and UTI , two grade 4 sepsis and one grade 5 death toxicities.
Combination of afatinib at doses higher than 20mg with carboplatin and paclitaxel should be administered with caution due to the toxicities. Pharmacokinetics and pharmacodynamics of carboplatin administered in a high-dose combination regimen with thiotepa, cyclophosphamide and peripheral stem cell support. Exposure to carboplatin was studied in treatment days by measuring the area under the carboplatin plasma ultrafiltrate pUF concentration vs time curve AUC.
The AUC was obtained by using a previously validated limited sampling model. A total of 31 patients was studied who received one, two or three courses of this high-dose chemotherapy regimen. The unbound, plasma ultrafiltrate carboplatin was almost completely cleared from the body before each next treatment day in a course; the day-to-day AUC variation was 3.
The mean cumulative AUC over 4 days was In 97 treatment days the carboplatin dose was calculated using the Calvert formula with the creatinine clearance as the measure for the glomerular filtration rate GFR. There were no relationships found between toxicity and the AUC of carboplatin , which may be due to the influence of overlapping toxicities of cyclophosphamide and thiotepa.
However, the ototoxicity was strongly related to the cumulative carboplatin AUC. This toxicity was dose limiting for carboplatin in this schedule. It appeared that the carboplatin pharmacokinetics in these regimens were similar to those reported at conventional dosages.
To reduce the inter-patient variation, the carboplatin dose can be calculated using the Calvert-formula with the creatinine clearance as the measure for the GFR. Concurrent chemotherapy and radiation therapy RT are used to treat patients with esophageal cancer. The optimal combination of chemotherapeutic agents with RT is not well established. After completion, the disease was restaged and patients were evaluated for surgery. Secondary objectives included determination of non-DLTs, as well as preliminary radiographic and pathologic response rates.
Twelve patients were enrolled 11 men, 1 woman. All were assessable for toxicity and efficacy. Of these 6 patients, 4 underwent esophagectomy and none achieved a pathologic complete response.
Esophagectomy was performed in 3 patients, with 2 achieving a pathologic complete response. In this small study, this regimen appears active, but toxic. We retrospectively analysed 59 patients with relapse or refractory DLBCL 38 male patients and 21 female patients presenting between June and June The 2-year overall survival rate was The 2-year progression free survival rate was Combination of paclitaxel and carboplatin as second-line therapy for patients with metastatic melanoma.
Patients with metastatic melanoma MM have very few therapy options. Data regarding patients treated with PC were abstracted from medical records. Clinical outcomes as determined by the treating oncologist were used for this analysis. Thirty-one patients with MM were treated with PC. The median time to disease progression for the entire group was 3 months range, mos , with a median overall survival of 7.
The clinical benefit derived by the 14 patients, which lasted for a median of 5. At the time of last follow-up, eight patients continued to receive PC therapy.
Further evaluation of this regimen, alone or as a 'backbone' for other agents, needs to be considered. Rationale for combining immunotherapy with chemotherapy. Immunotherapy has usually been considered as an alternative to more traditional modalities. Moreover, it has previously been felt that chemotherapy is inherently immunosuppressive and not suitable for combining with immunotherapy. In this review, the concept of combining different modalities that result in cell death, such as radiotherapy and chemotherapy , with immunotherapy is explored.
Additionally, several chemotherapy agents at low doses selectively inhibit regulatory and suppressor cells. In phase 2, a total of 94 and 47 evaluable patients were assigned to arms 1 and 2, respectively. No difference in median progression-free survival was observed between arms 1 and 2 6. A total of 21 patients had a treatment-emergent adverse event leading to death 18 in arm 1 and 3 in arm 2 ; for 10 individuals, this was an infection pneumonia or sepsis deemed to be related to the study drug.
Published by Elsevier Inc. Dose-related nephrotoxicity of carboplatin in children. This study investigated changes and the time course of these changes in renal function in children following treatment with carboplatin , and identified risk factors for nephrotoxicity. Glomerular and proximal renal tubular function were investigated before and up to 2 years after treatment in 23 children who received carboplatin.
The main findings were reduced glomerular filtration rate GFR , and increased renal tubular loss of magnesium, manifested by a low serum magnesium S Mg. No patient had a clinically important reduction in GFR, and only one patient had symptomatic hypomagnesaemia. GFR and S Mg did not change over time after completion of treatment. Dose intensity DI of carboplatin was not shown to be related to S Mg following treatment.
High CDs of carboplatin may be associated with evidence of renal damage qualitatively similar to but less severe than that caused by cisplatin. GFR and SMg should be carefully monitored when high CDs of carboplatin are used, or if carboplatin is combined with other nephrotoxic chemotherapy. The epidermal growth factor receptor EGFR tyrosine kinase inhibitor gefitinib was initially approved in Japan in for the treatment of advanced or metastatic non-small-cell lung cancer NSCLC ; however, the optimal order of conventional cytotoxic chemotherapy carboplatin and paclitaxel and gefitinib administration has not been determined.
We conducted a randomized phase II study of carboplatin and paclitaxel followed by gefitinib vs. Carboplatin and paclitaxel were administered in 4 cycles every 3 weeks; gefitinib was continued until disease progression or development of unacceptable toxicity. The primary endpoint was overall survival; the secondary endpoints were response rate and adverse event prevalence.
The median overall follow-up was The major toxicities were hematological carboplatin and paclitaxel or skin rash, diarrhea and hepatic dysfunction gefitinib. Interstitial lung disease was observed in 1 patient from each arm.
In arms A and B, the carboplatin and paclitaxel response rate, gefitinib response rate, and median survival durations were Arm A was selected for a subsequent phase III study. In this clinical trial, researchers will test whether the addition of the drug combination vincristine, topotecan, and cyclophosphamide to a standard chemotherapy regimen improves overall survival in patients with extracranial Ewing. Combination studies of platinum II -based metallointercalators with buthionine-S,R-sulfoximine, 3-bromopyruvate, cisplatin or carboplatin.
With current chemotherapeutic treatment regimes often limited by adverse side effects, the synergistic combination of complexes with anticancer activity appears to offer a promising strategy for effective cancer treatment. Synergistic relationships were observed, indicating a potential to decrease dose-dependent toxicity and improve therapeutic efficacy.
Feasibility of adjuvant chemotherapy with S-1 plus carboplatin followed by single-agent maintenance therapy with S-1 for completely resected non-small-cell lung cancer: This multicenter study evaluated the feasibility of novel adjuvant chemotherapy with S-1 plus carboplatin followed by single-agent, long-term maintenance with S-1 in patients with completely resected stage II-IIIA non-small-cell lung cancer NSCLC.
Patients unable to continue S-1 plus carboplatin because of severe toxicity converted to single-agent S-1 maintenance. Eighty-nine patients were enrolled, of whom 87 were eligible and assessable.
The treatment completion rate was There were no treatment-related deaths. The 2-year relapse-free survival rate was We concluded that adjuvant chemotherapy with S-1 plus carboplatin followed by single-agent maintenance therapy with S-1 is feasible and tolerable in patients with completely resected NSCLC. In the present work an attempt was made to gain greater therapeutic effect of diazane coupled with adriamycin and sarcolysin.
Leucemias L and La served as a model. In leucosis La diazane was injected once in 5 days. Either an additional injection of adriamycin two days prior to diazane injection or sarcolysin injected simultaneously with diazane enabled the authors to obtain a distinct synergestic effect. In leucemia L a simultaneous administration of diazane and sarcolysin also contributes to considerably longer survival of leucemic animals.
Such combinations are likely to be promising in their clinical use. We evaluated the prevalence of and risk factors for hypersensitivity reactions related to carboplatin , which is commonly used to treat gynecological malignancies. All women with pathologically documented ovarian, fallopian tube, or primary peritoneal cancer treated with carboplatin alone or a carboplatin -based combination chemotherapy regimen at a single hospital between January and December were retrospectively recruited.
We analyzed the incidence, characteristics, risk factors, management, and outcomes of carboplatin -related hypersensitivity reactions among these patients. Among eligible women, 75 The annual incidence of carboplatin -related hypersensitivity reactions gradually increased from 0. Therefore, disease severity, histological type, malignant ascites, past drug allergies, and cumulative carboplatin dose are risk factors for carboplatin -related hypersensitivity reactions. Such reactions could potentially be reduced or prevented by slowing the infusion rate and using a desensitization protocol involving anti-allergy medications.
However, its applicability is restricted mostly to patients responding to salvage chemotherapy. Optimal salvage regimen for these patients is unclear. In this study, our aim was to compare the efficacy profiles of ifosfamide, carboplatin , and etoposide ICE and etoposide-steroid-cytarabine-cisplatin ESHAP cytosine arabinoside, cisplatin, and dexamethasone regimens in the salvage treatment of relapsed or refractory HD.
Of patients, 47 Response could be evaluated in patients. Carboplatin is in a class of medications Metastatic seminoma is a highly curable disease. Standard treatment comprises of combination chemotherapy. The short- and long-term toxicities of this treatment are increasingly recognised and the possibility of over treatment in such a curable disease should be considered.
We have therefore assessed the use of single agent carboplatin at a dose of AUC 10 in patients with good prognosis metastatic seminoma. Patients with good prognosis metastatic seminoma treated with carboplatin AUC 10 were identified at our institution and affiliated institutions.
Treatment was three weekly for a total of three or four cycles. Outcome and toxicities were analysed. Three-year survival was There were no treatment related deaths. Single agent carboplatin at a dose of AUC 10 is an effective treatment for good prognosis metastatic seminoma. The outcome compares favourably to previously published outcomes of combination chemotherapy.
Although haematological toxicity is a concern, single agent carboplatin treatment for good prognosis metastatic seminoma could be considered a treatment option and is associated with less toxicity than combination regimens currently used. Overview of different available chemotherapy regimens combined with radiotherapy for the neoadjuvant and definitive treatment of esophageal cancer.
Neoadjuvant chemoradiotherapy CTRT is the current standard of care for treatment of locally advanced cancer of the esophagus or gastroesophageal junction. Many efforts have been made over the last years to identify the best chemotherapy and radiotherapy combination regimen, but specific randomized trials addressing this issue are still lacking. A systematic review of the literature was performed searching in PubMed all published studies of combinations CTRT regimens for operable or unresectable esophageal cancer to describe activity and toxicity.
Studies considered were prospective series or clinical phase II-III trials including at least 40 patients and published in English language. Long-term results of CROSS trial have established RT combined with carboplatin plus paclitaxel chemotherapy as the preferred neoadjuvant treatment option for both squamous and adenocarcinoma of the esophagus.
More effective multimodal treatment strategies integrating novel biological agents including immunotherapy and based on an extensive molecular tumor characterization are eagerly awaited.
EMP combination chemotherapy and low-dose monotherapy in advanced prostate cancer. Many chemotherapeutic regimens combined with estramustine phosphate EMP have been elaborated for the treatment of hormone-refractory prostate cancer over 30 years. In addition, an interim report in 83 patients was presented. They were not consecutively enrolled but were treated on low-dose EMP monotherapy for previously untreated advanced prostate cancer in Department of Urology of Tokyo University and our 21 affiliated hospitals.
Overall PSA response rate was as high as However, overall toxicity rate was abnormally high The reason of low drug compliance may be attributed to gastrointestinal symptoms. To overcome the low drug compliance, appropriate patients for EMP administration should be selected by using gene analysis on the basis of sophisticated tailor-made medicine.
Background Sorafenib, a multikinase inhibitor of cell proliferation and angiogenesis, inhibits the mitogen-activated protein kinase pathway that is activated in most uveal melanoma tumors. This phase II study was conducted by the SWOG cooperative group to evaluate the efficacy of sorafenib in combination with carboplatin and paclitaxel CP in metastatic uveal melanoma.
Methods Twenty-five patients with stage IV uveal melanoma who had received 0—1 prior systemic therapy were enrolled. The primary endpoint was objective response rate ORR ; a two-stage design was used with the study to be terminated if no confirmed responses were observed in the first 20 evaluable patients. Conclusion In this study, the overall efficacy of CP plus sorafenib in metastatic uveal melanoma did not warrant further clinical testing when assessed by ORR, although minor tumor responses and stable disease were observed in some patients.
Efficacy of preoperative transcatheter arterial chemoembolization combined with systemic chemotherapy for treatment of unresectable hepatoblastoma in children.
The purpose of this study was to evaluate, retrospectively, the clinical efficacy of preoperative transcatheter arterial chemoembolization TACE combined with systemic chemotherapy for unresectable hepatoblastoma.
Five boys and three girls mean age Mean tumor diameter and mean alfa-fetoprotein AFP level were For all patients, preoperative systemic chemotherapy was administered before TACE.
At each TACE, carboplatin and adriamycin mixed with iodized oil were infused into the feeding arteries. Tumor response and prognosis after treatment were evaluated. Mean tumor shrinkage was In all cases TACE combined with systemic chemotherapy enabled subsequent safe and complete surgical resection.
Preoperative TACE combined with systemic chemotherapy was effective in inducing surgical resectability of unresectable hepatoblastoma. The genetic and clinical heterogeneity of breast cancer makes the identification of effective therapies challenging. We designed I-SPY 2, a phase 2, multicenter, adaptively randomized trial to screen multiple experimental regimens in combination with standard neoadjuvant chemotherapy for breast cancer.
The goal is to match experimental regimens with responding cancer subtypes. In this ongoing trial, women are eligible for participation if they have stage II or III breast cancer with a tumor 2.
Patients undergo adaptive randomization within each biomarker subtype to receive regimens that have better performance than the standard therapy. Regimens are evaluated within 10 biomarker signatures i.
Veliparib- carboplatin plus standard therapy was considered for HER2-negative tumors and was therefore evaluated in 3 signatures. The primary end point is pathological complete response. Tumor volume changes measured by magnetic resonance imaging during treatment are used to predict whether a patient will have a pathological complete response.
Regimens move on from phase 2 if and when they have a high Bayesian predictive probability of success in a subsequent phase 3 neoadjuvant trial within the biomarker signature in which they performed well.
A total of 72 patients were randomly assigned to receive veliparib- carboplatin , and 44 patients were concurrently assigned to receive control therapy; at the completion of chemotherapy , the estimated rates of pathological complete.
High-dose chemotherapy with haemopoietic stem-cell rescue improves event-free survival in patients with high-risk neuroblastoma; however, which regimen has the greatest patient benefit has not been established. We aimed to assess event-free survival after high-dose chemotherapy with busulfan and melphalan compared with carboplatin , etoposide, and melphalan. We did an international, randomised, multi-arm, open-label, phase 3 cooperative group clinical trial of patients with high-risk neuroblastoma at institutions in 18 countries that included an open-label randomised arm in which high-dose chemotherapy regimens were compared.
Patients age years with neuroblastoma were eligible to be randomly assigned if they had completed a multidrug induction regimen cisplatin, carboplatin , cyclophosphamide, vincristine, and etoposide with or without topotecan, vincristine, and doxorubicin and achieved an adequate disease response. Patients were randomly assigned 1: Doses of busulfan and melphalan were modified according to bodyweight.
Stem-cell rescue was given after the last dose of. Carboplatin -induced immediate hypersensitivity reactions are relatively common among patients with gynecological malignancies. Once this occurs, the patient might be at risk for future carboplatin -induced reactions.
This study evaluated the efficacy of allergic consultation, carboplatin skin testing and desensitization as a single intervention strategy in this population. Patients with a well-documented immediate reaction to carboplatin were offered allergy consultation, carboplatin skin testing and a desensitization plan in a single visit between scheduled chemotherapy sessions. Fifty-five patients with an immediate reaction were evaluated.
A total of carboplatin desensitization cycles were administered to 49 women. Among them, 10 patients had a mild immediate hypersensitivity reaction during desensitization. Five patients subsequently tolerated carboplatin administered in the prolonged desensitization protocol.
In the data presented, we propose a strategy that is both cost effective and very convenient for the patient. The diagnostic procedure, including allergist consultation and skin test, can be completed in less than 2 h. In most cases where carboplatin is indispensable, desensitization can be administered without overnight hospitalization.
The toxicity of radiotherapy RT combined with weekly carboplatin and adjuvant carboplatin and etoposide was prospectively assessed in a group of patients with high-risk Stage I and II Merkel cell carcinoma of the skin. Patients were eligible if they had disease localized to the primary site and lymph nodes, with high-risk features.
This was followed by three cycles of carboplatin and etoposide. A total of 18 patients were entered into the study, and their data were compared with the data from 53 patients entered into the Trans-Tasman Radiation Oncology Group Treatment was completed as planned in 16 patients.
The weekly carboplatin dose was delivered in 17 patients, and 15 were able to complete all three cycles of adjuvant carboplatin and etoposide. Grade 3 and 4 neutrophil toxicity occurred in 7 patients, but no cases of febrile neutropenia developed. The results of our study have shown that weekly carboplatin at this dosage is a safe way to deliver synchronous chemotherapy during RT for MCC and results in a marked reduction of febrile neutropenia and Grade 3 skin toxicity compared with the three weekly regimen.
Oxaliplatin-capecitabine OxCap and carboplatin -paclitaxel CarPac based neo-adjuvant chemoradiotherapy nCRT have shown promising activity in localised, resectable oesophageal cancer. A non-blinded, randomised 1: Surgery was performed weeks after nCRT. Primary end-point was pathological complete response pCR. Eighty five patients were randomised between October and February from 17 UK centres. Three of 85 3. Twelve of 41 Both regimens were well tolerated. Only CarPacRT passed the predefined p.
Carboplatin versus alternating carboplatin and doxorubicin for the adjuvant treatment of canine appendicular osteosarcoma: Despite numerous published studies describing adjuvant chemotherapy for canine appendicular osteosarcoma, there is no consensus as to the optimal chemotherapy protocol.
The purpose of this study was to determine whether either of two protocols would be associated with longer disease-free interval DFI in dogs with appendicular osteosarcoma following amputation. Dogs with histologically confirmed appendicular osteosarcoma that were free of gross metastases and underwent amputation were eligible for enrollment.
Dogs were randomized to receive either six doses of carboplatin or three doses each of carboplatin and doxorubicin on an alternating schedule. Fifty dogs were included. Toxicity was similar between groups. These results suggest that six doses of carboplatin may be associated superior DFI when compared to six total doses of carboplatin and doxorubicin.
Most patients are diagnosed at an advanced stage, palliative chemotherapy therefore being the only treatment option. This study was aimed at evaluating the health-related quality of life HRQoL of advanced-stage NSCLC patients receiving palliative chemotherapy with carboplatin and paclitaxel. Physical and cognitive functioning scale scores differed significantly among chemotherapy cycles, indicating improved and worsened HRQoL, respectively.
A phase I trial of the novel farnesyl protein transferase inhibitor, BMS, in combination with paclitaxel and carboplatin in patients with advanced cancer.
This phase I study was conducted to determine the toxicities, pharmacokinetics, and pharmacodynamics of BMS, a farnesyl transferase inhibitor, in combination with paclitaxel and carboplatin , in patients with advanced solid tumors. Patients with solid tumors received one of six escalating dose levels of BMS infused over 1 hour given following paclitaxel and carboplatin on the first day of a day cycle. Toxicities were graded by the National Cancer Institute common toxicity criteria and recorded as maximum grade per patient for each treatment cycle.
Inhibition of farnesyl transferase activity in peripheral blood mononuclear cells PBMCs was evaluated. Thirty patients received cycles of treatment through six dose levels. Dose-limiting toxicities were neutropenia, thrombocytopenia, nausea, and vomiting.
There was no pharmacokinetic interaction between BMS and paclitaxel. One measurable partial response was observed in a patient with taxane-resistant esophageal cancer. There was partial regression of evaluable disease in two other patients endometrial and ovarian cancer.
The combination of BMS with paclitaxel and carboplatin was well tolerated, with broad activity in solid tumors. Primary frontal sinus squamous cell carcinoma in three dogs treated with piroxicam combined with carboplatin or toceranib. To our knowledge, this is the first publication concerning canine pFS-SCC, diagnosed using histology or cytology and medical imaging, in three dogs.
The tumours extended into the orbit or brain cavity, without nasal involvement. Treatment was initiated with piroxicam- carboplatin. Prolongation of carboplatin delivery with a low dose intensity was performed on dogs with a favourable initial response. Dog 1 achieved a complete remission CR , but was euthanized days after start of therapy. Dog 2, still alive 3 years after start of therapy and in CR, received 14 carboplatin deliveries.
In dog 3, after changing the treatment protocol into piroxicam-toceranib, a significant tumour reduction occurred, but the dog was euthanized after days because of a relapse. Targeting chemotherapy -resistant leukemia by combining DNT cellular therapy with conventional chemotherapy. While conventional chemotherapy is effective at eliminating the bulk of leukemic cells, chemotherapy resistance in acute myeloid leukemia AML is a prevalent problem that hinders conventional therapies and contributes to disease relapse, and ultimately patient death.
We have recently shown that allogeneic double negative T cells DNTs are able to target the majority of primary AML blasts in vitro and in patient-derived xenograft models. Given the differences in the modes of action of DNTs and chemotherapy , we hypothesize that DNT therapy can be used in combination with conventional chemotherapy to further improve their anti-leukemic effects and to target chemotherapy -resistant disease.
Drug titration assays and flow-based cytotoxicity assays using ex vivo expanded allogeneic DNTs were performed on multiple AML cell lines to identify therapy-resistance. Primary AML samples were also tested to validate our in vitro findings.
Further, a xenograft model was employed to demonstrate the feasibility of combining conventional chemotherapy and adoptive DNT therapy to target therapy-resistant AML. Lastly, blocking assays with neutralizing antibodies were employed to determine the mechanism by which chemotherapy increases the susceptibility of AML to DNT-mediated cytotoxicity. Here, we demonstrate that KG1a, a stem-like AML cell line that is resistant to DNTs and chemotherapy , and chemotherapy -resistant primary AML samples both became more susceptible to DNT-mediated cytotoxicity in vitro following pre-treatment with daunorubicin.
Moreover, chemotherapy treatment followed by adoptive DNT cell therapy significantly decreased bone marrow engraftment of KG1a in a xenograft model. Our results demonstrate the feasibility and benefit of using DNTs as.
Carboplatin binding to histidine. An X-ray crystal structure showing the binding of purely carboplatin to histidine in a model protein has finally been obtained. This required extensive crystallization trials and various novel crystal structure analyses. Carboplatin is a second-generation platinum anticancer agent used for the treatment of a variety of cancers.
Previous X-ray crystallographic studies of carboplatin binding to histidine in hen egg-white lysozyme; HEWL showed the partial conversion of carboplatin to cisplatin owing to the high NaCl concentration used in the crystallization conditions.
Here, it is reported that a partial chemical transformation takes place but to a transplatin form. Thus, to attempt to resolve purely carboplatin binding at histidine, this study utilized co-crystallization of HEWL with carboplatin without NaCl to eliminate the partial chemical conversion of carboplatin. Tetragonal HEWL crystals co-crystallized with carboplatin were successfully obtained in four different conditions, each at a different pH value.
The structural results obtained show carboplatin bound to either one or both of the N atoms of His15 of HEWL, and this particular variation was dependent on the concentration of anions in the crystallization mixture and the elapsed time, as well as the pH used. The structural details of the bound carboplatin molecule also differed between them.
Overall, the most detailed crystal structure showed the majority of the carboplatin atoms bound to the platinum centre; however, the four-carbon ring structure of the cyclobutanedicarboxylate moiety CBDC remained elusive. The potential impact of the results for the administration of carboplatin as an anticancer agent are.
Pembrolizumab is a humanized monoclonal antibody which serves to enhance the antitumor immune response by targeting programmed cell death 1 receptor. However, numerous immune-mediated toxicities of pembrolizumab have been reported. Follow-up PET-CT scanning showed a very good response at the level of the tumor but new-onset activity in bilateral hilar and mediastinal lymph nodes.
Biopsy of these lymph nodes revealed a benign pathology with noncaseating granulomas consistent with immune-mediated sarcoidosis. The pathogenesis of immunotherapy-induced sarcoidosis is not yet known but has been reported in different cancers and using different checkpoint inhibitors.
To our knowledge, this case is the first in the literature displaying pulmonary sarcoidosis in a patient with NSCLC 4 months after having initiated chemotherapy plus pembrolizumab combination therapy. Background Pembrolizumab is a humanized monoclonal antibody which serves to enhance the antitumor immune response by targeting programmed cell death 1 receptor. Conclusion The pathogenesis of immunotherapy-induced sarcoidosis is not yet known but has been reported in different cancers and using different checkpoint inhibitors.
However, this regimen requires hospitalization to ensure proper hydration and continuous infusion of 5-FU, and causes severe nausea and anorexia. Primary end point was overall response rate. Secondary end points were safety, treatment completion rate, progression-free survival, overall survival, and clinical benefit rate. Planned sample size was 45 patients.
Forty-seven subjects were accrued from July to October Median overall survival was A potentially treatment-related death occurred in one patient with intestinal pneumonia. The PCE regimen shows promising. Consistent with the synergistic to additive antitumor activity the combination index ranging from 0. Removal of paclitaxel increased the repair of carboplatin -DNA adducts: Chemotherapy combinations for cancer treatments harbor immense therapeutic potentials which have largely been untapped.
Of all diseases, clinical studies of drug combinations are the most prevalent in oncology, yet their effectiveness is disputable, as complete tumor regressions are rare. Our research has been devoted towards developing delivery vehicles for combinations of chemotherapy drugs which elicit significant tumor reduction yet limit toxicity in healthy tissue.
Current administration methods assume that chemotherapy combinations at maximum tolerable doses will provide the greatest therapeutic effect -- a presumption which often leads to unprecedented side effects. Contrary to traditional administration, we have found that drug ratios rather than total cumulative doses govern combination therapeutic efficacy.
In this thesis, we have developed nanoparticles to incorporate synergistic ratios of chemotherapy combinations which significantly inhibit cancer cell growth at lower doses than would be required for their single drug counterparts. The advantages of multi-drug incorporation in nano-vehicles are many: To exploit these advantages for polychemotherapy delivery, two prominent nanoparticles were investigated: Liposomes represent the oldest class of nanoparticles, with high drug loading capacities and excellent biocompatibility.
Polymer-drug conjugates offer controlled drug incorporations through reaction stoichiometry, and potentially allow for delivery of precise ratios. Here, we show that both vehicles, when armed with synergistic ratios of chemotherapy drugs, significantly inhibit tumor growth in an aggressive mouse breast carcinoma model.
Furthermore, versatile drug incorporation methods investigated here can be broadly. Phase I study of the c-raf-1 antisense oligonucleotide ISIS in combination with carboplatin and paclitaxel in patients with previously untreated, advanced non-small cell lung cancer.
The carboplatin dose was then increased to AUC fp 6 mg. The maximum tolerated dose was established by toxicity during the first two day cycles of therapy. The pharmacokinetics of all three agents was determined before and during the ISIS infusion. Dose-limiting neutropenia occurred in two patients at dose level 3. Grade 3 and 4 nonhematologic toxicities were infrequent and limited to nausea and constipation.
The maximum tolerated doses were carboplatin AUC fp 6 mg. There were no objective responses and the concurrent infusion of ISIS did not alter the plasma pharmacokinetics of paclitaxel or total platinum. ISIS can be safely combined with standard doses of carboplatin and paclitaxel.
Combining cytotoxic chemotherapeutic agents with inhibitors of aberrant signal transduction mediated by Raf proteins produced no objective responses in the dose and schedule administered in this study. Combination chemotherapy is widely exploited for enhanced cancer treatment in clinic.
However, the traditional cocktail administration of combination regimens often suffers from varying pharmacokinetics among different drugs. The emergence of nanotechnology offers an unparalleled opportunity for developing advanced combination drug delivery strategies with the ability to encapsulate various drugs simultaneously and unify the pharmacokinetics of each drug.
This review surveys the most recent advances in combination delivery of multiple small molecule chemotherapeutics using nanocarriers. The mechanisms underlying combination chemotherapy , including the synergistic, additive and potentiation effects, are also discussed with typical examples. We further highlight the sequential and site-specific co-delivery strategies, which provide new guidelines for development of programmable combination drug delivery systems.
Clinical outlook and challenges are also discussed in the end. To explore the feasibility and activity of a histology-based induction combination chemotherapy for elderly patients with clinical stage III non-small cell lung cancer NSCLC.
