BACKGROUND: There is no standard treatment for patients with colorectal cancer (CRC) progressing after irinotecan and oxaliplatin treatment. Here we aimed to retrospectively evaluate the efficacy and tolerability of raltitrexed in combination with oral 5-fluoropyrimidine (uracil tegafur-UFT) or mitomycin C as salvage therapy in mCRC patients.
MATERIALS AND METHODS: A total of 62 patients who had received raltitrexed combined with UFT or mitomycin C were identified between December 2008 and June 2013. They were given raltitrexed 2.6 mg/m2 (max 5 mg) i.v. on day 1 in combination with either oral UFT 500 mg/day on days 1-14 every 3 weeks (group A) or mitomycin C 6 mg/m2 i.v. on day every 3 weeks (group B).
RESULTS: Forty-two patients (67.7%) were in group A and 20 (32.2%) in group B. In 15 patients (24%) grade 3/4 toxicity was observed, resulting in dose reduction, and in 13 patients (20.9%) dose delay was necessary. The median progression free survival (PFS) was 3 months (95%CI 2.65-3.34) and median overall survival (OS) was 6 months (95%CI 2.09-9.90) in the whole group. Median PFS was 3 months (95%CI 2.60-3.39) in group A vs 3 months (95%CI 1.64-4.35) in group B (p=0.90). Median OS was 6 months (95%CI 2.47-9.53) in group A vs 12 months (95%CI 2.83-21.1) in group B (p=0.46).
CONCLUSIONS: The combination of raltitrexed with UFT or mitomycin C seem to be a salvage therapy option due to safety profile and moderate clinical activity in heavily-pretreated mCRC patients.
