Forty-eight aged patients over 75 years old operated on for primary lung cancer, which represented 12.6% of all resected patients for the same disease, were retrospectively studied for surgical outcomes. There were 37 males and 11 females. The eldest patients was 86 years old and 14 patients were over 80. Twenty-five patients were in stage I, 8 in stage II, 11 in stage IIIA, 3 in stage IIIB, and one in stage IV. Histologically 48 resected specimens included each 17 adenocarcinomas and squamous cell carcinomas and 14 other cell types. Pneumonectomy was carried out in 3, lobectomy in 41, segmentectomy in 1, and partial resection of the lung in 3 cases. The cumulative 5 year-survival rate was 20.7% as a whole, showing no histological difference. It is considered that poor surgical outcomes might be lie in frequent occurrence of postoperative complications, and predominance of cases (as much as 31) of relative non-curative resection. Pulmonary functional studies were not helpful in predicting postoperative pulmonary complications. Preoperative general evaluation including intellectual mental function, performance status, and positiveness in daily life, as well as pulmonary function are necessary in aged patients. The elderly patients in performance status 2 and 3 had a tendency to increase complications than those in P.S. 0 and 1. Five-year survival rate of 20.6% in relative non-curative resection cases was not significantly differ from that (16.7%) in absolute non-curative resection cases. Pulmonaly resection with R2 should be performed ever in the aged patients as a rule. |
