The contribution of discrimination analysis to the diagnostic decision in patients with lung carcinoma.

A set of 620 patients was examined. Out of them, 245 suffered from lung carcinoma of different type and stage, 28 suffered from other malignant tumors, 37 were affected with benign tumors, and 166 were suffering from a nonmalignant respiratory disease (tuberculosis, nonspecific pneumonia, chronic bronchitis, abscesses, cysts, asthma, lung fibrosis, bronchiectasis and sarcoidosis). In addition to these patients, 144 blood donors were examined who represented the control group of healthy individuals.

Serum esterase activity during the surgical therapy of bronchogenic carcinoma.

Serum esterase activity was estimated in 148 patients with bronchogenic carcinoma and in 19 patients with pulmonary tuberculosis before operation, 1 week and 3 weeks after operation. We failed to prove significant differences between the patients with malignant and nonmalignant lung diseases. We failed also to prove significant differences between the mean esterase activity findings regarding to the extent of surgery.
