Sequential moderate-dose methotrexate and 5-fluorouracil in advanced gastric adenocarcinoma.

A total of 23 patients with advanced gastric adenocarcinoma were treated with a combination of moderate-dose methotrexate (MDMTX), 250 mg/m2 i.v., with folinic acid rescue and 5-fluorouracil (5-FU) 600 mg/m2 i.v. Therapy was given every 7 days for 4 courses and then at 14-day intervals. All patients were evaluable for response. No complete responses occurred, but five patients (22%) had partial remissions (95% confidence limit, 5%-39%). The median duration of remission was 6 months, with a median survival of 11 months amongst responding patients. In all, six patients (26%) had stable disease for a median period of 5 months. The overall median survival was 6 months. Therapy was generally well tolerated, with principal toxicities consisting of neutropenia, nausea and vomiting, mucositis and diarrhoea. In terms of activity or survival in advanced gastric carcinoma, the combination of moderate-dose MTX and 5-FU does not appear to offer an advantage over single-agent therapy.
