title: [A case of gastric carcinoma disappearing after short-term preoperative chemotherapy].
abstract: A 58-year-old male visited the Kochi Municipal Central Hospital on May 17, 1984. A barium meal study and endoscopy revealed a huge crater surrounded by a thick embankment on the posterior wall of the stomach body. Biopsy specimens taken from the lesion revealed tubular adenocarcinoma, UFT (600 mg/day) and anti-tuberculous drugs were administered due to the complication of pulmonary tuberculosis. Endoscopic examination on August 6, 1984, revealed a remarkable improvement, showing a shallow irregular depression with converging folds. The patient underwent surgery on August 7, 1984, because from the endoscopic appearance, residual cancer was highly suspect, and also tuberculosis had improved. The histology of the surgically resected specimen showed a chronic peptic ulcer, the base of which was covered with regenerating mucosa. No cancer nests were demonstrated even by serial tissue sections.
