The primary aims of this study were activity and toxicity evaluation of a new raltitrexed and oxaliplatin-based regimen, as a first-line chemotherapy, in patients with metastatic colorectal cancer (MCC). Survival evaluation was considered a secondary endpoint.


Forty-four patients were enrolled into this phase II trial. Treatment consisted of raltitrexed 3 mg/m2 iv on d 1 and oxaliplatin 70 mg/m2 iv on d 1 and d 8 every 3 wk.


Twenty patients (45.5%) achieved a response [95% confidence interval (CI): 30.1% to 54.1%], 18 (40.9%) had stable disease, and only 6 (13.6%) developed progressive disease. After a median follow-up time of 14.7 mo (range 6.3-18.6 mo), the median time to disease progression was 6 mo (range 2.0-16.7) (95% CI: 4.4-7.6) and the overall survival was 14.8 mo (range 3-23) (95% CI: 11.2-18.4). Neutropenia was the most common hematological side effect, while transient AST/ALT increase, neurotoxicity, asthenia, and diarrhea were the most common nonhematological side effects.


Our data confirmed that oxaliplatin administered weekly plus raltitrexed is an active combination in newly diagnosed patients with advanced colorectal carcinoma that merits further investigation versus the classic schedule in a randomized, phase III trial.
