[Prognostic factors in resectable non-small-cell bronchial carcinoma]

This study represents the univariate and multivariate analysis of prognostic factors of resectable non small cell-lung cancer (NSCLC) that included 360 patients who underwent a surgical treatment because of primary (NSCLC) in the aforementioned institution in a period between 1985 and 1992. Patients with incomplete resection were rejected, perioperative deaths were not included in the analysis. In the analysed group there were 2931 (81.38%) males and 67(18.62%) females--M:F ratio 4.37:1. Age of the operated patients was 36-75 years with the mean age of 55.15 years. Right-sided tumours existed in 197(54.72%) patients, left-sided tumours in 163(45.28%) patients. Based on pTNM, 157, 65, 114, 18 and 6 patients were classified into stages I, II, IIIA, IIIB and IV respectively. In the univariate analysis, survival curves were obtained using the life table method, with the statistical analysis of the obtained data using the Gehan-Wilcoxon method. In the multivariate analysis--Cox regression analysis was performed. Multivariate analysis found only T-stage, N-stage and the stage of the disease as significant independent prognostic factors. Mode of influence of factors that were found significant in the univariate analysis (age 60 years, tumour diameter 60 mm, involvement of the visceral pleura, indirect tumour signs) is discussed and compared with literature data. Survival differences depending on other factors (tumour location, bronchoscopic aspect, extent of the resection), although without statistical significance, can be useful for the clinician, in the same time contributing to the better comprehension of informations obtained by basical investigations, especially of lymphatic spread of the disease and tumour pathology.
