[Results of pulmonary resections in elderly patients with primary lung cancer].
Forty-one patients over the age of 70 years, who had been operated upon for a primary lung cancer during 13 years until August, 1988, were reviewed. There were 32 males and 9 females, among whom the oldest was an 85-year-old male. These patients composed of 28.7% of the patients who had undergone a resectional lung surgery due to a primary lung cancer during the same period of time. These included 26 patients of stage I, 11 of IIIA, 3 of IIIB and 2 of IV. Twenty-two of them were with a squamous cell carcinoma, 18 with an adenocarcinoma, and one with a small cell carcinoma. Thirty-two patients underwent a lobectomy, including two undergoing a sleeve lobectomy. Three patients underwent a left pneumonectomy, and seven underwent a segmentectomy or a wedge resection. A combined chest wall resection was done in 5 of them. One patient underwent the second surgery for a metastasis to the contralateral lung following a left pneumonectomy. Our safety criteria of pulmonary functions for surgery were as follows; a predicted postoperative %VC greater than 40% for any type of pulmonary resection, a preoperative FEV1.0 greater than 1,000 ml for lobectomy and that greater than 1,300 ml for left pneumonectomy. These criteria were identical to those for patients younger than 70 years of age. But some patients even with respiratory functions slightly less than these lower limits did tolerate lobectomies or pneumonectomies. The latter patients, however, cleared what we call "one-flight test" as well as the other patients did.(ABSTRACT TRUNCATED AT 250 WORDS)
