This study was designed to assess the treatment of patients in whom a second primary lung cancer developed after the resection of primary lung cancer. ⋯ Surgical resection is feasible and effective in the management of second primary lung cancer, and sublobar resection may be adequate. Long-term surveillance of more than 5 years is essential for early detection to increase the chance of resection of a second primary lung cancer.
