This paper describes a clinical review of cases of gastric cancer treated surgically at the Department of Surgery of the Shirakawa Kosei General Hospital, the core medical institution in the southern part of Fukushima Prefecture.
During the period of 20 years from January 1981 through December 2000, a total of 1, 132 cases were operated on for gastric carcinoma. Surgical resection cases totaled 1, 023 (resection ratio: 90.4%); curative resection cases, 894 (curative resection ratio: 79.0%); 5-year survival rate for resection cases, 68.3%; and 5-year survival rate for curative resection cases, 75.6%. When the cases were divided into those treated during the first half of the 20 years nad those treated during the latter half of the 20 years, the number or resection cases was smaller during the latter than during the first half but the resection ratio was larger. The early stomach cancer cases in terms of the degree of progress, histological classification, depth and metastasis to lymph nodes have been increasing and the 5-year survival rate has been on the rise.

During the period of 25 years from January 1978 through December 2002, a total of 808 colorectal cancer cases were operated on in Shirakawa Kosei General Hospital. The number of sugical resection cases came to 713 (ratio : 88.25%). Curative resection was performed on 593 cases (ratio : 73.4%). The total number of cases was broken down into 446 cases of cancer of the colon and 369 cases of cancer of the rectum (7 multiple cancer cases included). By sex, male cases numbered 329 and female cases 379. Clinically or histologically, many cases were diagnosed as stage IIIa or stage II cancer. The 5-year-survival rate for the resection cases was calculated at 67.2% and that for the cure resection cases, at 79.5%.
