[Intra-aortic infusion therapy with sequential methotrexate (MTX) and 5-FU in advanced gastric carcinoma]

Fifteen patients with advanced gastric carcinoma were treated by intraaortic infusion therapy with sequential MTX and 5-FU. Intraaortic bolus injection with 50-100 mg/body MTX was followed 3 hours later with 500-750 mg/body 5-FU and 24 hours later with 30 mg/body leucovorin. Treatment was repeated weekly. Of these 15 patients who were evaluated, 4 had PR and 3 had MR. Response rate was 27%. Two patients had WBC nadir of less than 3,000 cells/mm and other two had a platelet count nadir of less than 10/mm. Gastrointestinal symptoms such as nausea and vomiting were mild. Three patients had diarrhea and 3 had mucositis. No other toxicity was seen. This regimen has been well tolerated for long periods.
