A Clinical Study of Synchronous Multiple Primary Lung Cancer

Abstract

Nine patients with synchronous multiple primary lung cancer were reported. They consisted of 8 men and 1 woman with a mean age of 67.4 years (rang 45 to 83 years). Of them, 7 patients had ipsilateral masses and 2 had bilateral masses. The incidence of synchronous multiple primary lung cancer among all resected lung cancers was 2.2%. There was some difficulty in differentiating synchronous lung cancer from metastatic lesions by using only conventional criteria. Even in case of bilateral disease, good results can be expected by successful management by combining surgery with systemic chemotherapy and transbronchoscopic procedures.
