Abstract
Recently, the number of patients with lung cancer and pulmonary mycobacteriosis has been increasing. Over the last 10 years, we operated on 10 patients with lung cancer and active pulmonary mycobacteriosis, including atypical mycobacteriosis, at Toneyama National Hospital. All cases were male, with a mean age of 61 years. All of them had a history of smoking. Histological types of lung cancer were squamous cell carcinoma in 7 cases and adenocarcinoma in 3 cases. Clinical stages were stage IA in 4 cases, stage IB in 2 cases, stage IIB in 1 case and stage IIIA in 3 cases. Either before or after the operation, 4 cases had multiple primary cancers. In all cases, the operation was performed after adequate chemotherapy for pulmonary mycobacteriosis. The operative procedure was lobectomy in 7 cases, lobectomy and chest wall resection in 1 case, pneumonectomy in 1 case, and partial resection in 1 case. In the postoper ative period, no recurrence of pulmonary mycobacteriosis was found.
It is reported that lung cancer is more frequent among patients with pulmonary mycobacteriosis than healty individuals; thus, patients with pulmonary mycobacteriosis must be carefully followed up.
