[Tuberculosis and lung cancer].

In the Wroclaw province in the years 1976-1980 basing on the analysis of 1,351 medical records pulmonary tuberculosis and lung cancer was coexistent in 224 cases (17%). Erroneous diagnosis of tuberculosis instead of lung cancer was made in 35 patients (1% of all tuberculosis cases). Out of 224 cases with coexistent tuberculosis and lung cancer, 38 were registered in the active tbc groups, while 82 in the non-active group. In 44% of the patients with the coexistent tbc and lung cancer and 34% of the patients with the erroneous diagnosis of tbc the first contact doctor (general practitioner) made the correct diagnosis. Patients from ambulatory care groups IIB, IA and non-active tbc are at high risk of developing lung cancer.
