ABSTRACT: PURPOSE:Irinotecan, in combination with leucovorin/5-fluorouracil (FU) or with cisplatin, is known to be active for treating advanced gastric cancer (AGC). This pilot study evaluated a novel three-drug combination of irinotecan, leucovorin/FU and cisplatin as a first-line treatment of AGC. The primary endpoint was to assess the feasibility in anticipation of conducting a larger phase II study. MATERIALS AND METHODS:Chemotherapy-naive AGC patients received irinotecan 150 mg/m(2) on day 1, and leucovorin 200 mg/m(2) and a 22-h infusion of FU 1000 mg/m(2) on days 1 and 2. Cisplatin 30 mg/m(2) was administered on day 2. Treatment was repeated every 2 weeks until disease progression or unacceptable toxicity. RESULTS:Of the 17 eligible patients, two patients had an ECOG performance status of 2 and their median age was 48 years (range: 31 to 69). A total of 117 chemotherapy cycles were delivered (median: 6, range: 1 to 12). The causes of treatment discontinuation were disease progression in 9 patients (53%), refusal (35%) and toxicity (12%). Although grade 3 or 4 neutropenia (41% of patients) was the major toxicity that required dose adjustments, only one episode of febrile neutropenia occurred. Grade 3 or 4 nausea and vomiting, diarrhea and fatigue were observed in 35%, 35% and 29% of patients, respectively. None of the patients died of toxicity during treatment. Of the 16 patients who were evaluable for response, 7 (44%) experienced a partial response. CONCLUSION:This novel multi-drug combination was tolerated well in patients with AGC. Based on the encouraging efficacy and tolerability, a randomized phase II study is ongoing in this disease setting.
