Critical evaluation of results of extension of indication for surgery for primary bronchogenic carcinoma

Abstract

Among 3,120 surgically resected cases (1957-1983) in Shanghai Chest Hospital, 1,476 resections (47.3%) were performed under extended indication. Six categories--(1) aged 70-87 years (102), (2) associated with severe impairment of pulmonary function (25), (3) small-cell anaplastic type (143), (4) stage III lesion (1,145), (5) invading carina (29), (6) with disseminated pleural metastasis and effusion (32)--were critically evaluated. For the first four categories, long-term survival rates were very encouraging, whereas only technical advancement and short-term results were discussed for the last two. The authors present strategic points significant in availing higher overall operability and hence the overall survival rate, shedding light on the increase of curative potential for lung cancer.
