Surgery of gastric cancer in patients over 80 years old.

A retrospective study on postoperative complications and factors affecting prognosis was performed on elderly patients with gastric cancer. We studied the correlation of age, pathological depth, preoperative laboratory data, physical status, duration of surgery, volume of blood loss, blood transfusion, curability, and extent of lymph node dissection to postoperative complications and prognosis in 47 patients with gastric cancer over 80 years old. Preoperative function of lung and liver frequently showed abnormal data. Postoperative complications were noted in 47% of patients, especially in the pulmonary system, liver and heart. Curability and extent of lymph node dissection were the significant factor affecting survival. Some mortalities caused by initial malignancy were recognized in the conservative lymph node dissection in the stage I. The incidence of postoperative complications was not significantly different according to extent of lymph node dissection. Blood transfusion was the only significant factor for the incidence of postoperative complication. The most frequent cause of death was the initial malignancy. We recommend that a low grade lymph node dissection should not be readily chosen for elderly patients in early cases.
