Occult blood in stool was discovered in 54. 1%. 87.9% (525 cases) was operable, among´525 cases of operated patients, 58.0% (306 cases, was resected. and 47.5% (249 cases) was curatively resected. In spite of mass palpable in the epigastric area resectability was 56%.
In the group of stomach cancer with pyeoric stenosis, hyperacidity and peptic ulcer like symptoms and older age, resectability were high.
On the location of tumors, 66.7% found in pylorus and antrum(350 cases), 17.2% in bqdy(91 cases) 6.6% in cardia and fundus(34, cases), 9.5% in the almost entire stomach wall(50 cases)
