چکیده

AIM To determine if the drug doses and administration schedules of carboplatin and gemcitabine combination affect antitumor effects. MATERIALS AND METHODS The inhibition of cell viability was measured by MTT assay. Median effect analysis was conducted to determine the cytotoxicity activity of carboplatin and gemcitabine combination. Cell cycle changes were analyzed by flow cytometry. RESULTS Synergism was observed when the bladder cancer cell line 5637 cells were treated with gemcitabine followed by carboplatin or concurrent carboplatin/gemcitabine. In contrast, moderate antagonism was observed when cells were treated with carboplatin followed by gemcitabine. Cell cycle analysis showed that the combined effect of these two drugs was cell cycle disturbance. CONCLUSION Different doses and administration schedules affect the antitumor effect of carboplatin/gemcitabine combination that may have clinical significance in the treatment for bladder cancer.

Pretreatment with dexamethasone increases antitumor activity of carboplatin and gemcitabine in mice bearing human cancer xenografts: in vivo activity, pharmacokinetics, and clinical implications for cancer chemotherapy.

PURPOSE The present study was undertaken to determine the effects of dexamethasone (DEX) pretreatment on antitumor activity and pharmacokinetics of the cancer chemotherapeutic agents carboplatin and gemcitabine. EXPERIMENTAL DESIGN Antitumor activities of carboplatin and gemcitabine with or without DEX pretreatment were determined in six murine-human cancer xenograft models, including cancers...

Gemcitabine/carboplatin combination regimens: importance of dose schedule.

Platinum compounds, either cisplatin (Platinol) or carboplatin (Paraplatin), in combination with a number of new chemotherapeutic agents, have demonstrated improved response or survival compared to cisplatin alone or older platinum-based regimens. Gemcitabine (Gemzar)-platinum combinations are of particular interest because of their interactive mechanisms of action, demonstrated preclinical syn...

Gemcitabine-containing regimens vs others in first-line treatment of NSCLC.

Standard first-line chemotherapy regimens in advanced non-small-cell lung cancer (NSCLC) include carboplatin (Paraplatin)/paclitaxel, cisplatin/docetaxel (Taxotere), cisplatin/gemcitabine (Gemzar), and cisplatin/vinorelbine (Navelbine). An informal meta-analysis of 13 randomized trials of these regimens in NSCLC indicates no marked differences in terms of response rates or survival, but toxicit...

Gemcitabine in combination with trastuzumab and/or platinum salts in breast cancer cells with HER2 overexpression.

Trastuzumab (Herceptin) is an effective treatment in patients with HER2-overexpressing metastatic breast cancer. Risk of trastuzumab-induced cardiotoxicity raises concerns regarding combined use with anthracyclines or other potentially cardiotoxic agents following anthracycline treatment. We characterized interactions between trastuzumab and gemcitabine (Gemzar) and the combination of gemcitabi...
