抄録

The authors evaluated the results of limited resection of lung cancer in 31 patients over 70 years old. Ages ranged from 70 to 84 (mean 75.9). The indications for limited operations were (1) peripherally located tumor with a diameter of less than 3 cm, (2) no hilar or mediastinal lymph node metastasis and no distant organ metastasis, and (3) poor cardiopulmonary reserve. Twenty-eight patients underwent segmentectomy and three wedge resection. In cancer of the right lung, resection of the anterior and posterior segments of the upper lobe was most commonly performed and in cancer of the left lung, the upper division segment of the upper lobe or apical segment of the lower lobe were most commonly resected. The pathological cell types were adenocarcinoma in 23 patients, squamous cell carcinoma in 6 and others in two.<BR>There was no operative death or hospital death. Postoperative complications occurred in 10 patients (32.3%). The overall 5-year survival rate of the patients who underwent limited resection was 43.5%, while that of stage I cases was 52.5%.<BR>Limited resection for lung cancer in patients over 70 years is effective in selected cases because of good curability and low mortality.
