Results of surgical treatment of synchronous multiple primary lung carcinomas.

Four male patients with synchronous multiple lung carcinoma were operated on. In one patient both tumours were adenocarcinomas; both were bronchioloalveolar carcinomas in a second patient. In a third patient the tumours were adenocarcinoma and bronchioloalveolar carcinoma while in the fourth patient an adenocarcinoma and a squamous cell carcinoma were present. One patient was asymptomatic and free from carcinoma at follow-up examination 11 years and 7 months after the operation. The other three died of pulmonary carcinoma 11 months, 1 year 3 months and 9 years 8 months postoperatively.
