OBJECTIVE: This study aimed at comparing the efficacy of FLEP chemotherapy in the treatment of stage IV AFP-producing gastric cancer and stage IV non-AFP-producing gastric cancer. METHODS: Between 1989 and 2002, 57 patients with stage IV inoperable gastric cancer were given a combination of chemotherapy with 5-fluorouracil (5-FU), leucovorin (LV), etoposide (VP-16) and cis-diamminedichloroplatinum (CDDP) (designated as FLEP). In the two groups classified histologically according to AFP positivity, the rate of response and conversion to surgery, disease-free and overall survival were compared. The disease-free and overall survival in the two groups was compared by a log-rank test. RESULTS: Patients of the AFP-producing group had a significantly better response rate (70 vs. 31.9%, p = 0.03) and a better conversion rate (40 vs. 12.8%, p = 0.04) than those of the non-AFP-producing group. Patients of the AFP-producing group also had a significantly better disease-free and overall survival (p = 0.02) than those of the non-AFP-producing group. AFP-producing gastric cancer was identified as an independent prognostic factor. CONCLUSION: FLEP chemotherapy was more effective for stage IV AFP-producing gastric cancer than in stage IV non-AFP-producing gastric cancer. Preoperative FLEP chemotherapy improved the prognosis of AFP-producing gastric cancer because of downstaging. Copyright 2004 S. Karger AG, Basel
