Objetives: Retrospectively to analyse the influence of clinical and histo-pathological characteristics in the local recurrence after non-small cell lung cancer surgery. Method: 146 patients were included and studied during a minimum of two years. The free survival of disease function (FSD) was constructed according to the Kaplan-Meier method. The univariante comparison of the FSD by Mantel-Haenszel means of logarithmic ranks test and the multivariante analysis by Cox regression model. Results: In the univariante analysis 20 months of FSD and the following predicting factors of a smaller FSD: Radiological contact of the tumour with the pleura (p = 0.005), peritumoral margin affectation (p = 0.001), pleural affectation (p = 0.006), T stratification factor (p = 0.04) and N factor (p = 0.002). Other factors like age, initial symptoms, second neoplasias, radiological spiculaciones or cavitations, transtoracic puncion, type of surgery, peribronquial affectation, so large margin tumorlike and histological type, did not show statistically significant differences in the FSD. In the multivariante study they maintain its value prognosis the pleural affectation (p = 0.0014), ganglionary affectation (p = 0.02) and degree of differentiation (p = 0.03). Conclusions: The most important prognosis factor of local recurrence after surgery in these patients were the infiltration of the pleura, followed of the hilio-mediastínica ganglionary affectation and the degree of histological differentiation.
