[The role of oxaliplatin in the therapy for advanced colorectal carcinoma].
The role of oxaliplatin in the therapy for advanced colorectal carcinoma. Preclinical models and numerous phase I to III trials have demonstrated the efficacy of oxaliplatin (l-OHP) for colorectal carcinoma. In previously untreated patients, response rates with l-OHP plus 5-fluorouracil and leucovorin (5-FU/LV) have been shown to be more than twice as high as compared with 5-FU/LV alone, and progression-free intervals have been significantly increased. Nevertheless, overall-survival was similar in both treatment arms, that was possibly due to the cross-over-design of these studies. Moreover, the combination regimens with l-OHP and 5-FU/LV often have shown activity in 5-FU-resistant or 5-FU- refractory patients. Furthermore, treatment of previously unresectable liver metastases from colorectal carcinoma with l-OHP in combination with 5-FU/LV has provided promising results. Dose-limiting toxicity is a peripheral sensory neuropathy, that was found to be mostly completely reversible within a few months. Gastrointestinal toxicities have been demonstrated to be mild. Compared to other anticancer drugs currently used in the treatment for colorectal carcinoma, l-OHP not only shows a different mechanism of action but displays synergistic anti-tumor activity as well as minimal hematologic toxicity making this agent interesting for combination chemotherapy protocols. In conclusion, the development of l-OHP has essentially increased the therapeutical possibilities of treatment for colorectal carcinoma.
