We have shown previously that gamma-glutamyl transpeptidase (GGT) activity is essential for the nephrotoxicity of cisplatin. In this study we asked whether GGT activity was necessary for the antitumor activity of cisplatin. GGT was transfected into PC3 cells, a human prostate tumor cell line. Two independent GGT-positive cell lines were isolated and characterized. GGT cleaves extracellular glut...
Numerous studies have shown cisplatin-based chemotherapy to be effective in the treatment of head and neck cancer. Cisplatin/5-fluorouracil (5-FU) is the most frequently used combination regimen, but neurotoxicity, ototoxicity, and renal toxicity limit repeated dosing (for long-term treatment of responding patients) and dose intensification. In studies to date, the analogue carboplatin appears ...
PURPOSE Paclitaxel and cisplatin, active drugs in the treatment of non-small-cell lung cancer (NSCLC), have been found to be synergistic and less myelotoxic in combination when the paclitaxel is given 24 hr prior to the cisplatin. Their antitumor activity and toxicity in patients with advanced NSCLC has been evaluated herein. MATERIALS AND METHODS Seventy-four chemonaive patients, with advanc...
BACKGROUND This nonrandomized study compared 2 radiochemotherapy regimens for toxicity in 128 patients with stage III/IV head and neck cancer. METHODS Patients received conventionally fractionated radiotherapy. The total dose to primary tumor and involved lymph nodes did depend on preceding surgery. Patients received 66 to 70 Gy if surgery was not performed, 60 to 66 Gy after R0 resection, 66...
Cisplatin is an extremely effective cancer chemotherapeutic agent, but its use is often accompanied by toxicity. Second generation drugs such as carboplatin are becoming more widely used because of reduced toxicity. Since biotransformation products have been implicated in the toxic responses, we have begun to investigate the reactions of cisplatin and carboplatin with potential biological ligan...
Objective: The clinical use of cisplatin is highly restricted, because of its nephrotoxicity.In this study the protective effect of Nigella sativa (N. sativa) against cisplatin-induced nephrotoxicity was investigated in rats. Materials and Methods: In the current study, the effects of the administration of aqueous-ethanolic extract of N. sativa (100 and 200 mg/kg, BW) and vitamin E (100 mg/kg, ...
Cisplatin/gemcitabine association has been a standard of care for first-line regimen in advanced biliary tract cancer nevertheless oxaliplatin/gemcitabine regimen is frequently preferred. Because comparative effectiveness in clinical outcomes of cisplatin- versus oxaliplatin-containing chemotherapy is not available, a systematic review of studies assessing cisplatin/gemcitabine or oxaliplatin/g...
Cisplatin is one of the most effective chemotherapeutics, but its usefulness is limited by its toxicity to normal tissues, including cells of the kidney proximal tubule. The purpose of these studies was to determine the mechanism of cisplatin cytotoxicity. It was shown in vivo that cisplatin administration induces upregulation of the gene for the p21 cyclin-dependent kinase (cdk) inhibitor in k...
Cisplatin is a highly effective anti-cancer chemotherapeutic agent; however, its clinical use is severely limited by serious side effects, of which nephrotoxicity is the most important. In this study, we investigated whether Qiong-Yu-Gao (QYG), a popular traditional Chinese medicinal formula described 840 years ago, exhibits protective effects against cisplatin-induced renal toxicity. Using a m...
Ovarian cancer is one of the most common gynecologic malignancies (Suh et al., 2012). Because of rare specific symptoms and lack of feasible screening methods, more than two-thirds of patients with ovarian cancer are diagnosed at advanced-stage disease, which leads to poor prognosis. Taxanes and platinum-based chemotherapy after surgery has been established as the first line treatment by previo...
