[Tuberculosis and cancer: primary lung cancer cases after treatment with anti-tuberculous drugs].

Out of 939 primary lung cancer cases (histologically confirmed), 54 cases had received treatment with anti-tuberculous drugs before diagnosis of lung cancer was made. Fifty-one percent of the cases were detected by the mass survey and 55.6% of them were adenocarcinoma. The duration of treatment for tuberculosis was less than 3 months in 63.0% and more than 13 months in 5.6% of the cases. Surgery for lung cancer was performed in 25 cases (46.3%). The ratio of surgical intervention for patients previously treated with anti-tuberculous drugs was not different from that for patients who had received no anti-tuberculous drugs.
