Abstract: Objective To explore the association between pulmonary tuberculosis (PTB) and carcinoma, and study the clinical diagnosis and treatment of PTB complicated with carcinoma.Methods Eighty-nine PTB patients complicated with carcinoma were analyzed retrospectively. Results All patients were non-small cell lung cancer (81), and SCLC (8), the stage of NSCLC was Ⅰ(11), Ⅱ(4), Ⅲa (15), Ⅲb and Ⅳ (51). In all patients, 49 cases were treated by anti-tuberculosis ,9 cases quitted the treatment, and in 81 patients of NSCLC, 26 patients accepted operation. In 53 patients in late stage of NSCLC, 30 cases accepted mainly chemotherapy with synthetic method, 23 cases quitted the treatment. Conclusions PTB complicated with carcinoma is prone to miss diagnosis or misdiagnosis, because PTB is similar to carcinoma in clinical manifestation and chest radiological study. If the effective treatment could be chosen, the patients would survive longer.
