Aim. The aim this study is to determine the characteristics, survival, and factors affecting the survival of resected T3 non-small cell lung cancer.
Methods. The records of 97 cases were retrospectively reviewed with T3 non-small cell lung cancer patients that were operated between 1996-2001. Complete resection was achieved in 71 (73.2%) patient. The distribution of N status was 47.4%, 28.9%, and 23.7% for N0, N1 and N2 respectively. The evaluated prognostic factors in univariate and multivariate analyses were, histologic type, type of resection, N status, subgroups of pT3, resection margins and effect of adjuvant therapy.
Results. Overall 5-year survival rate was 24.3%. Median survival and 5-year survival of the patients whose tumors resected completely was 33 months and 31.5%, whereas 18 months and 7.3% for the patients resected incompletely (P=0.03). Median survival being not significantly different among the three subgroups: 25, 23, and 32 months (P=0.7) in the bronchial pT3, mediastinal pT3, and periheral pT3 subgroups, respectively. Histology (P=0.57), type of surgical resection (lobectomy versus pneumonectomy) (P=0.25), and use of adjuvant therapy (P=0.054) did not influence the survival significantly. However N status influenced the survival significantly (P=0.01). According to the multivariate analyses, two factors were selected as prognostic indicators: N2 status (P=0.03) and incomplete resection (P=0.03).
Conclusion. Three pT3 subgroups did not show survival differences. Complete resection and N2 status are the two most influencing factors in survival of the patients. Adjuvant theraphy effected the survival and the quality of life reversely.
