Abstract
The risk of developing multiple primary lung carcinoma is rare (1.07%) but increases with time following resection of the first primary lesion. Eight well-documented cases are reported along with a review of 351 cases reported in the literature. The interval between metachronous lesions ranged from 9 months to 17 years. Surgical resection remains the preferred treatment of resectable nonsmall cell carcinoma, with 5 year survival of 11%. All patients with lung carcinoma should be followed-up for the rest of their lives because of the possible occurrence of a second primary.
