BACKGROUND: We conducted two phase II trials evaluating the combination of 5-fluorouracil/folinic acid, oxaliplatin and irinotecan (FOLFOXIRI) as first-line treatment in 74 metastatic colorectal cancer patients. Results were very promising with an overall response rate of 71% and 72%, a median PFS of 10.4 and 10.8 months and an overall survival of 26.5 and 28.4 months, respectively. A concern about the use of all three active agents up-front is the possibility that this might limit, after progression, disease control with second-line treatments. Therefore, we conducted the present analysis to evaluate the outcome of second-line treatments in these 74 patients.
METHODS: Among the 71 patients so far progressed 54 (76%) received second line chemotherapy (23: FOLFIRI, 17: FOLFOXIRI, five: 5-FU protracted infusion, three: FOLFOX, three: 5-FU+MMC, two: CPT-11, one: CPT-11+LOHP, one: raltitrexed). Seventeen patients (24%) did not receive second line treatments: 10 because of deterioration of performance status (PS), four because of patient refusal and three because of death. Patients' characteristics at the time of second-line treatment were: M/F 36 of 18 patients, median age 64 yrs (range 44-75), ECOG PS>or=1 21 (39%) patients, multiple sites of disease 33 (61%) patients.
RESULTS: A median of 4.1 months of second-line chemotherapy per patient were administered (range 1-8). Overall response rate (52 out of 54 evaluable patients) was 33% and stable disease were 19 (37%). Median duration of response was 8.1 months. At a median follow up of 15.1 months from the start of salvage chemotherapy median PFS and overall survival were respectively 6.7 and 15.2 months.
CONCLUSIONS: First-line FOLFOXIRI does not impair the possibility to obtain objective responses and delay tumor progression with second line treatments containing the same agents used in first-line.
