Özet

Objectives: The tumor size is an important prognostic factor in non-small cell lung cancer (NSCLC). However, a criterion for tumor size has remained unchanged for the last 25 years in TNM classification. The purpose of this study was to determine the relationship between tumor size and survival in patients with non-small cell lung cancer. Method: Of 550 consecutive patients who underwent operation for NSCLC between 1994 and 1998, we reviewed the medical record of 509 patients. There were 470 men and 39 women. Survivals were compared according to groups of tumor size (Group 1: less than or equal to3 cm, Group II: 3.1-4 cm, Group III: 4.1-5 cm, Group IV: >5 cm, Group A (II + III): 3.1-5 cm, and Group B (IV): >5 cm). The Cox proportional hazard model was used with same variables.
