AIMS AND BACKGROUND: Irinotecan (CPT-11) has been tested as a single agent in several studies, and response rates of 18-23% have been reported in first-line gastric cancer therapy. In the present study we report the safety and efficacy results combining CPT-11 with 5-fluorouracil (5-FU) and folinic acid (FA). PATIENTS AND METHODS: Thirty consecutive patients with metastatic gastric cancer, considered in poor clinical condition, were treated with CPT-11 and 5-FU/FA according to the FOLFIRI regimen. All enrolled cases were evaluable for toxicity and drug activity. RESULTS: The main grade 3-4 toxicity (according to the NCI-CTC criteria) was neutropenia (16%, grade 4 in 1 patient); non-hematological grade 3 toxicity consisted mainly in vomiting and diarrhea reported in 1 patient. No treatment-related serious adverse events were observed. Response was obtained in 12 patients (40%), stable disease in 2 patients (7%), while progression was documented in 16 patients (53%). CONCLUSIONS: These results are very promising, and suggest that the combination of CPT-11 plus 5-FU/FA is active and well tolerated and can be considered as useful treatment in patients with metastatic gastric cancer in poor clinical condition.
