We investigated the association between creatinine clearance (Ccr), a marker of renal function, and the toxicity and efficacy of oxaliplatin in patients with metastatic colorectal cancer (mCRC). Patients and Methods: Patients with mCRC who received oxaliplatin-based chemotherapy as first-line treatment were included in this study. Primary outcome was peripheral neuropathy (Grade ≥2), while secondary outcomes included neutropenia (Grade ≥3), thrombocytopenia (Grade ≥2) and overall survival (OS). Results: A total of 145 patients with mCRC were eligible. Incidence rates of peripheral neuropathy (Grade ≥2), neutropenia (Grade ≥3) and thrombocytopenia (Grade ≥2) were 30.3%, 37.2% and 16.6%, respectively, and median OS was 29.1 months. Cox proportional hazards analysis indicated that there was no significant relationship between Ccr and any adverse event, or between Ccr and OS. Conclusion: Dose reduction of oxaliplatin based on Ccr is not recommended in patients with mCRC.
