Long‐term surgical results of carcinoma of the gastric remnant: A statistical analysis of 613 patients from 98 institutions

Abstract

Abstract Based on a survey questionnaire sent to the 98 member institutions of the Japanese Research Society for Gastric Cancer, 613 cases of cancer of the gastric remnant, after resection for a variety of benign and malignant conditions, were collected and reviewed. This study includes both recurrences and newly developed cancers, although only cases with an accurate diagnosis and careful follow‐up were selected. An analysis of the time intervals between initial gastrectomy for cancer and second operation suggests that recurrences usually occur within 10 years of the first procedure, while those cancers developing after 10 years are likely to represent new lesions. The cumulative 5‐year survival rates of 48.7% after subtotal and 28.9% after resection for carcinoma of the gastric remnant are no worse than those for cancer resections in the stomach previously untreated surgically. An active approach based on early detection and aggressive surgical therapy of these lesions is recommended.
