AIMS AND BACKGROUND: Soon after the approval of irinotecan for second-line therapy of advanced gastric cancer, the FOLFIRI regimen represented a possible treatment choice in clinical practice. However, there was still scarce data on the efficacy of irinotecan in this setting. We retrospectively evaluated the efficacy of FOLFIRI as second-line treatment in advanced gastric cancer patients progressing after platinum-based chemotherapy. METHODS: Patients with metastatic gastric cancer progressing after platinum-based chemotherapy who received FOLFIRI as second-line chemotherapy were included in our analysis. RESULTS: Thirty patients were consecutively treated (20 males and 10 females). Median age was 62 years (range, 36-78). All patients had metastatic disease. In 17 cases (56.6%), peritoneal tumor diffusion was present. Six patients (20%) had previously received 5-fluorouracil-based adjuvant chemotherapy. The median number of cycles administered was 4 (range, 1-12). Partial remission was obtained in 1 case (3%) and stable disease in 8 patients (27%). Median progression-free survival and overall survival were 2.7 months and 5.5 months, respectively. The most common toxicities (grade 2-3) observed were neutropenia (13.3%), diarrhea (10%) and vomiting (30%). Ten patients (10%) received 3 or less courses of chemotherapy. In these cases, treatment was stopped before scheduled for accelerated worsening of clinical conditions. CONCLUSIONS: FOLFIRI resulted scarcely active in metastatic gastric cancer patients pre-treated with platinum-based chemotherapy. In this setting, the real benefit of a second-line chemotherapy with the FOLFIRI regimen should be carefully re-considered, especially according to the clinical condition of the patient and possible treatment-related side effects.
