In a clinical trial of paclitaxel (Taxol) and carboplatin in combination, the severity of thrombocytopenia was less than would be expected with an equivalent dose of carboplatin alone. To determine whether a pharmacokinetic interaction was responsible for this observation, the effect of pretreatment with Taxol on the pharmacokinetics of carboplatin was examined in 11 patients. Each patient was ...

Purpose: Carboplatin-based regimens have proven efficacy in children with cancer. However, the development of hypersensitivity reactions (HSRs) may have a negative impact on treatment intensity and patients' outcome. The aim of this review is to summarize the incidence and the clinical features of HSRs occurring in children with cancer treated with carboplatin and their impact on treatment effi...

Intravitreal corticosteroids in the treatment of bacterial endophthalmitis remain controversial. We utilized an experimental rabbit model of methicillin-resistant Staphylococcus epidermidis endophthalmitis (i) to calculate the intravitreal vancomycin concentration in rabbit eyes receiving intravitreal vancomycin alone or in combination with intravitreal dexamethasone and (ii) to determine wheth...

OBJECTIVES The incidence of hypersensitivity reactions (HR) is increased in patients treated with multiple courses of carboplatin. The purposes of this investigation were to evaluate the effectiveness of a 12-step desensitization protocol and to characterize the immune mechanism of carboplatin HR. METHODS We analyzed 10 consecutive patients who had documented HR to carboplatin and in whom con...

BACKGROUND Wilms tumor (WT) is the most common pediatric malignant primary renal tumor. One of the main drugs used in treatment is actinomycin-D. This was not readily available in Turkey at one time. Carboplatin was used in the primary treatment of WT in order to prevent delays in treatment. The aim of this study is to present the results of patients with WT receiving carboplatin or actinomycin...

BACKGROUND. Since its clinical introduction in 1981, carboplatin has proved a feasible alternative to cisplatin for the treatment of many solid tumors, especially ovarian cancer. Because the pharmacokinetics and, ultimately, the pharmacodynamics of carboplatin are highly dependent on the status of renal function, fixed dosing based on body surface area has led to carboplatin overdosing or, espe...

Ovarian cancer is the fourth most ordinary cause of cancer-related deaths in women. In recent, combination chemotherapy with carboplatin and docetaxel was developed as first-line drug to treat ovarian carcinoma. However, the detailed molecular mechanism, which accounts for the cells to apoptosis induced by administration of carboplatin and docetaxel, was unrecognized. In present study, we provi...

BACKGROUND/AIMS SMAD7 is a key inhibitor of transforming growth factor β (TGFβ) receptor signaling, which regulates the alteration of cancer cell invasiveness through epithelial-mesenchymal cell conversion. Carboplatin is a commonly used drug in the chemotherapy for non-small cell lung cancer (NSCLC). Nevertheless, the molecular mechanisms underlying its suppressive effects on the NSCLC cell in...

Carboplatin, [Pt(NH3)2(CBDCA-O,O')], 1, where CBDCA is cyclobutane-1,1-dicarboxylate, is used against ovarian, lung, and other types of cancer. We recently showed (Di Pasqua et al. (2006) Chem. Res. Toxicol. 19, 139-149) that carboplatin reacts with carbonate under conditions that simulate therapy to produce carbonato carboplatin, cis-[Pt(NH3)2(O-CBDCA)(CO3)]2-, 2. We use 13C and 1H NMR and UV-...

The goal of our study was two-fold: (i) develop a robust 3D colony assay methodology to interrogate drug combinations using GelCount and (ii) to develop 2-drug combinations that might be useful in the clinic for the treatment of high-grade gliomas. We used three glioma cell lines (U251MG, SNB19, and LNZ308) and two adenocarcinoma cell lines (MiaPaCa and SW480) grown as colonies in a two-tiered ...
