title: [Effect of prior and co-existing lung diseases on the determination of the degree of spread of lung cancer].
abstract: The results of preoperative evaluation of tumor expansion and regional lymph node involvement were checked during surgery in 2 groups of lung cancer patients. Group 1 included 247 cases with preexisting and concomitant pulmonary pathology, while group 2-another 247 patients without such diseases. Errors in preoperative evaluation of tumor expansion were significantly more frequent in patients with concomitant pathology. Errors in assessing the nodal status were significantly more frequent in cases of preexisting and concomitant pulmonary diseases. The results may be useful in the choice of a surgical procedure for lung cancer.
