Abstract: Objective To investigate the clinical characteristics and surgical treatment of pulmonary tuberculosis complicated with lung cancer.
Methods The clinical data，surgical methods，pathological types，tumor stages，postoperative treatment strategies and related complications of 52 patients with lung cancer complicated with pulmonary tuberculosis admitted to our department from January 2015 to December 2017 were retrospectively analyzed.
Results There were 40 cases of stable tuberculosis and 12 cases of active tuberculosis.There were 40 cases of lobectomy，4 cases of compound lobectomy and 8 cases of total pulmonary resection.Twelve patients received anti-tuberculosis treatment before operation，and 25 patients received anti-tuberculosis and chemoradiotherapy simultaneously after operation.Perioperative complications occurred in 7 cases，and there were no perioperative deaths.
Conclusion Surgical resection is the first choice for lung cancer patients with pulmonary tuberculosis.Patients with lung cancer combined with active pulmonary tuberculosis should be anti-tuberculous for at least 2 weeks before surgery.Patients with lung cancer complicated with stable pulmonary tuberculosis should receive anti-tuberculosis treatment at the same time after radiotherapy and chemotherapy，both of which can be carried out at the same time.
