title: Carcinoma of the stomach in atomic bomb survivors. A comparison of clinicopathologic features to the general population.
abstract: The results of surgical treatment of gastric cancer were reviewed retrospectively for 135 atomic bomb survivors and 377 control patients. The mean age was significantly higher in the survivors than in the controls. Otherwise, both groups were quite comparative especially in terms of the stage of the disease. Histopathologically, the rates of poorly differentiated or undifferentiated types of carcinoma and secondary lymph node involvements were significantly lower in the survivors than in the controls. There were no significant difference between the two groups in postoperative morbidity and mortality rates and long-term survival rate. The incidence of second primary malignancies, however, was apparently higher in the survivors than in the controls.
