摘要：

Background. Increases in the detection of early gastric cancer have indisputably, improved long-term survival. The aim of this study was to establish the value of periodic gastric endoscopy and the appropriate intervals for its performance. Methods. We compared, retrospectively, the clinicopathologic characteristics and outcomes of two groups of patients who had undergone surgical treatment for gastric cancer. Of a total of 361 patients, 106 had undergone endoscopic examination within 2 years before the detection of gastric cancer (group 1), and 255 had either undergone no endoscopic examination or had had endoscopic examination more than 2 years before the detection of gastric cancer (group 2). For the evaluation of survival rate, the patients in each group were classified into two subgroups: group Ia, endoscopic examination within 1 year before detection; group lb, endoscopic examination more than 1 year and within 2 years; group 2a, endoscopic examination more than 2 years and within 4 years before detection; and group 2b, endoscopic examination more than 4 years before detection, or no endoscopic examination. Results. Gastric cancer in group 1 was characterized by small tumor size, no tumor invasion beyond the submucosa, few instances of lymphatic and vascular permeation, and few lymph node metastases. The 5-year survival rate for group 1 patients (96.5%) was significantly higher than that for group 2 patients (71.0%; P < 0.01). The survival rates for group 1a patients and group lb patients were not significantly different (P = 0.4595). The survival rate for patients in group 2a was significantly lower than that for those in group 1a (P < 0.05). Conclusion. Periodic gastric endoscopy enables early detection of cancer, thereby improving survival. The optimal interval for periodic examination appears to be 2 years.
