Background: Thirty-four patients with gastric cancer in stage II and III were enrolled, after curative resection, in a pilot study to assess the feasibility and the impact on relapse of a double modulation of 5-Fluorouracil (5FU) by Methotrexate (MTX) and 1-Leucovorin (LFA) as adjuvant chemotherapy.
Methods: The schedule was: MTX 500 mg/m2d. 1, LFA 250 mg/m2d.2, 5FU 600 mg/m2d.2. Cycles were repeated every two weeks for 16 times. Quality of life during treatment was evaluated with the EORTC QLQ-C30.
Results: At a median follow-up of 24 months, 21 (61%) patients treated with postoperative chemotherapy, were disease-free. Toxicity was primarily gastrointestinal, but its intensity was usually mild. The feasibility of treatment was also confirmed from the results of QLQ-C30 questionnaire.
Conclusions: This study demonstrates that the schedule tested is feasible as postoperative treatment in curatively resected gastric cancer patients and prompts the initiation of a randomized trial with a no-treatment control arm.
