摘要: While 5-fluorouracil used as single agent in patients with metastatic colorectal cancer has an objective response rate around 20%, the administration of combinations irinotecan 5-fluorouracil/folinic acid or oxaliplatin results significantly increased rates and improved survival. However, side effects systemic therapy such myelotoxicity, neurotoxicity gastrointestinal toxicity may lead to life-threatening complications have a major impact on quality life patients. Therefore, biomarkers that would be instrumental choice optimal type, combination dose drugs for individual patient are urgently needed. The efficacy anticancer tumor cells is determined by effective concentration cells, healthy tissues presence quantity drug targets. Enzymes active metabolism transport represent important determinants therapeutic outcome. aim this review was summarize published data associations gene protein expression, genetic variability putative 5-fluorouracil/leucovorin/oxaliplatin 5-fluorouracil/leukovorin/irinotecan regimens. Gaps knowledge identified aid design future research clinical trials.
