[A case of gastric cancer completely responding to sequential methotrexate and 5-fluorouracil therapy]

A case of an 81-year-old male with Borrmann II type was reported. The lesion was diagnosed histologically as undifferentiated adenocarcinoma. Biochemically modulated chemotherapy preceded by administration of Methotrexate (MTX) and followed by 5-fluorouracil (5-FU) was given to him. The procedure was weekly intermediate-dose therapy consisting of MTX 100 mg (i.v.) followed 3 hours later by 5-FU 600 mg (i.v.) with leucovorin rescue in the following 2 days. After this treatment was repeated 6 times, advanced gastric cancer disappeared on endoscopic and histological findings, so the patient was regarded as showing a complete response. Ths, this biochemically modulated chemotherapy was thought to be in effective method against gastric cancer.
