To clarify the characteristics of a cancer of the gastric remnant, clinicopathological findings were compared with those of a primary cancer located in the upper third of the stomach. Twenty-two patients had a laparotomy under a diagnosis of a newly appearing cancer of the gastric remnant 6 years and 6 months to 27 years after distal gastrectomy. The distal gastrectomies had been performed for cancer in 13 cases, for a peptic ulcer in 6 cases and for an other benign disease in 3 cases. A newly appearing cancer of the gastric remnant is defined as one in a patient who has survived for more than 10 years after the first distal gastrectomy or when the cancer is considered to have nothing to do with the first gastric lesion even if the second operation is performed within 10 years after the first operation. A lower resectability rate, a more advanced stage due to deeper serosal invasion and more frequent lymph node involvement especially in n3-4 and a poorer prognosis were indicated in patients with a newly appearing cancer of the gastric remnant than in 268 patients with a primary cancer located in the upper third of the stomach. In the histological classification, the differentiated type was more frequent in a newly appearing cancer of the gastric remnant than in the patients with primary cancer.
