Oxaliplatin-related thrombocytopenia is considered rare and mostly self-limited. We present the first reported fatal case due to this complication. A 64-year-old patient with metastatic colon cancer was admitted for his 24th course of chemotherapy with oxaliplatin and 24-hour infusion of fluorouracil and leucovorin. Consciousness changed on the next evening and deteriorated to deep coma within ...
This study was conducted to identify tumor types warranting Phase II clinical trials of oxaliplatin using the human tumor cloning assay. Oxaliplatin was tested at concentrations ranging from 0.5 to 50.0 microg/ml in 1-h and 14-day continuous exposures along with 1.4 microg/ml carboplatin and 0.2 microg/ml cisplatin for comparison. We defined in vitro response as tumor growth inhibition >50% of ...
The development of resistance to platinum drugs in cancer cells severely reduces the efficacy of these drugs. Thus, the discovery of novel drugs or combined strategies to overcome drug resistance is imperative. In addition to our previous finding that combined D-penicillamine with platinum drugs exerts synergistic cytotoxicity, we recently identified a novel therapeutic strategy by combining an...
Oxaliplatin (4 mg/kg), cisplatin (2 mg/kg with 20 mg/kg mannitol) and ormaplatin (2 mg/kg) were administered i.p. twice weekly for 4.5 weeks. Lactose injections (0.9%) were used as a control for oxaliplatin and 0.9% saline injections were used as a control for cisplatin and ormaplatin. Morphometric changes to dorsal root ganglia L4-L6 were quantitated as a measure of neurotoxicity. Drug treatme...
BACKGROUND Oxaliplatin is used to treat patients with colorectal cancer (CRC); however, half the patients fail to benefit. The excision repair cross-complementing group-1 (ERCC1) gene was studied and it was hypothesized that its inducible expression contributes to cellular resistance. MATERIALS AND METHODS Thirty CRC cell lines were treated with oxaliplatin and sensitivity was determined by a...
Oxaliplatin displays a wide spectrum of antitumor activities and is widely used in the treatment of metastatic colorectal cancer (CRC). However, tumor responses to this agent are variable, and the underlying mechanisms are poorly understood. In the present study, oxaliplatin was found to strongly inhibit the growth of HCT116 cells harboring wild-type p53 but to only weakly inhibit SW480 cells, ...
Oxaliplatin is included in a number of effective combination regimens used as first and subsequent lines of therapy for metastatic colorectal cancer. Accumulating evidence indicates that autophagy plays a significant role in response to cancer therapy. However, the role of autophagy in oxaliplatin-induced cell death remains to be clarified. In this study, we showed that oxaliplatin induced cell...
Oxaliplatin-induced chronic painful neuropathy is the most common dose-limiting adverse event that negatively affects cancer patients' quality of life. However, the underlying molecular mechanisms are still unclear. In the present study, we found that the intraperitoneal administration of oxaliplatin at 4 mg/kg for five consecutive days noticeably upregulated the expression of CXC motif ligand ...
PURPOSE Oxaliplatin is active in colorectal cancer. Sensory neurotoxicity is its dose-limiting toxicity. It may come from an effect on neuronal voltage-gated Na channels, via the liberation one its metabolite, oxalate. We decided to use Ca and Mg as oxalate chelators. EXPERIMENTAL DESIGN A retrospective cohort of 161 patients treated with oxaliplatin + 5-fluorouracil and leucovorin for advanc...
