Patients and Methods. We studied 64 patients with multiple primary lung cancer who underwent surgical treatment. Results. The average age at initial treatment was 64.3 years old.

There were two adenocarcinomas in different locations in 27 patients, two squamous cell carcinomas in 14, and the combination of an adenocarcinoma and a squamous cell carcinoma in 11. Thirty-five patients had two lesions diagnosed as p-stage I. Fourteen patients had a p-stage I lesion and a p-stage II lesion. In synchronous lung cancer, 14 patients underwent operation simultaneously, 11 patients underwent operation in two stages. Of 43 patients who underwent operations twice or more, 27 patients underwent lobectomies on the first operation. On the other hand, 28 patients underwent limited surgery on the second operation. Four patients underwent a lobectomy twice for metachronous bilateral lesions and three patients underwent completion pneumonectomy at the second operation. We encoun-1 2 3 870-8511 476
