title: [Surgical indication based on prognostic factors in pT1 tumors of the lung].
abstract: Among 385 patients of surgical resected lung cancer, 88 (22.8%) were pT1 tumors. The overall five year survival rate of these patients was 75.8%. There was statistically significant difference in survival rate depending on the pTNM staging, degree of differentiation and cytological atypia (CAT). Among these prognostic factors, CAT was most important. CAT may be an indicator to predict the postoperative prognosis of the patients and may contribute to the determination of the surgical indication.
