title: [5-year survival of resected bronchial cancer. Multifactorial analysis of its prognosis].
abstract: Prognosis in patients having undergone surgery for a bronchial carcinoma (oat cell. carcinoma excluded) was studied by comparing, with two statistical methods, a group of 178 patients surviving five years and more (group I) and a group of 178 patients who died within five years (group II). The two groups had undergone treatment during the same period. Comparison of the two groups suggested that the following factors were indicators of a good prognosis: ratio weight-height within normal limits without recent weight loss, fortuitous detection of the carcinoma; normal aspect on bronchoscopy; T1 N0 type without vascular extension, limited exeresis. Recurrences of the carcinoma were generally observed in group II but could be present in group I. The differential prognosis between pulmonary metastases and a "new" bronchial carcinoma was difficult. Survival was finally determined by the frequency of recurrences and metastases. By a correspondences factorial analysis it was possible to separate and to define the main characteristics of the patients with a good prognosis and a long survival and of those with a poor prognosis and a short survival. However this proved to be exact in only 30% of the individual cases because occurrence of metastases was generally unforeseable. From these data it appears that surgery alone is indicated in only one kind of tumours; T1 N0 carcinomas detected by routine examinations.
