| Popis: | Prognosis of patients with non small cell lung cancer (NSCLC) remains difficult to assess, even after adjustment for pathological stage. Prognostic value of numerous biological markers has been evaluated, with conflicting results. Data of 86 patients with NSCLC treated by surgery were collected with clinical characteristics, histopathological data including tumor differentiation and status of blood and lymphatic vessel invasion and evaluation by immunohistochemistry of Rb, Bcl-2 and Ki-67 expression. Prognostic values for overall survival (OS) and event-free survival (EFS) were analyzed by the log tank test and the multivariable Cox model. Using univariable analyses, pT, pN, poor differentiation or large cell subtype were associated with a poor OS, while lymphatic and/or blood vessel invasion were associated with a short EFS. None of the molecular markers had a significant prognostic value for either outcome. In multivariable analyses, only stage remained of prognostic value for OS. Interestingly, the presence of blood vascular invasion in the tumor was significantly predictive for subsequent metastatic occurrence in stages I and II. This feature might, therefore, be relevant for administration of adjuvant therapy in completely resected NSCLC. |
