[Systematic recording of malignant bronchopleuropulmonary tumors: value and limitations].

Abstract

A systematic recording of primary cancer of the bronchi, pleura or lung would be of descriptive, etiological and operational interest if the collected data were exhaustive, if it were possible to resolve the problems set by epidemiological surveys (the only kind of study to be considered) and finally if an effective means to fight against these cancers were available.
