ABSTRACT
Sixty patients with proven lung cancer were retrospectively studied to determine whether postoperative radiation therapy improves survival. Patterns of treatment failure and 5 year survival were assessed according to extent of tumor spread, histology, type of operation, positive resection margin and radiation dose. Of the 60 patients, excluding 5 patients who received incomplete treatment of poor pulmonary function, 55 patients received postoperative radiation therapy following curative resection. The overall survivial at 5 years was 39%. The hilar and mediasinal lymph node involvement had an influence on survival. The authors recommend that patients with resectable lung cancer involving the hilar and mediastinal lymph nodes may require postoperative radiotherapy to reduce the local recurrence and improve survival.
Key Words: Postoperative radiation therapy, Lung cancer, Lymph node
