Fluorouracil, doxorubicin, and mitomycin combination versus PELF chemotherapy in advanced gastric cancer: a prospective randomized trial of the Italian Oncology Group for Clinical Research.

Abstract

PURPOSE The combination of cisplatin, epirubicin, and leucovorin preceding fluorouracil (PELF) includes three novel agents compared with the standard combination of fluorouracil, doxorubicin, and mitomycin (FAM) in the treatment of advanced gastric carcinoma. We report the results of a prospective randomized comparison of the two combinations in previously untreated patients. PATIENTS AND METHODS One hundred thirty assessable patients were entered onto the trial; 52 received FAM and 85 PELF. A 1:2 unbalanced randomization in favor of the experimental treatment was chosen. Approximately 90% of patients had measurable tumor masses. RESULTS The overall response rates (complete responses [CRs] and partial responses [PRs]) were 15% and 43% for the FAM and the PELF regimens, respectively, with a statistically significant advantage for the experimental treatment (P = .001). Time to progression (median, 2.6 and 4.7 months), duration of response (median, 10.7 and 10.2 months), and survival durations (median, 5.6 and 8.1 months) were not significantly different between the FAM and PELF regimens, respectively. The PELF combination was more toxic compared with FAM, but generally tolerable. CONCLUSION This study showed that the PELF combination is about three times more effective than the FAM combination in inducing objective responses. Due to tolerability, it is not recommended for routine clinical use. However, it should be considered, among other second-generation chemotherapy combinations, in future randomized studies aimed to improve the therapeutic outcome in gastric carcinoma.
