Objective: Evaluate the survival and prognostic factors in EGFR mutation non-small cell lung cancer (NSCLC) patients treated with tyrosine inhibitors (TKI) in a Peruvian reference hospital. Methods: Retrospective cohort analytical observational study was conducted in NSCLC patients from 2009-2015. Kaplan-Meier curve was presented. For the bivariate analysis, the association between independent variables and survival is analyzed using the Long-Rank test. For the multivariate analysis, the Cox proportional hazards method is used to calculate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) using time-to-event outcomes. Results: Were included 72 patients, following for a total of 1144 months. Predominantly female gender (61.11%), never smoked patients (62.50%), histological adenocarcinoma subtype (76.38%). The most frequent EGFR mutation was the deletion of exon 19 (65.27%). The history of smoking was 37.5%. The majority of patients present with comorbidities (77.78%), hypertension being the most frequent. Almost all patients were found in stage IV. 65 (90.28%) cases died. It was estimated that the median survival was 9.3 months CI = 95% (7.01-16.93). When comparing the survival curves using Long Range Test, it was found that histological type (p = 0.01), place of mutation (p = 0.06), hemoglobin (p = 0.01) and age (p = 0.01) were significant for overall survival. In the multivariate analysis significant characteristicsthe were age (HR = 1.02, CI = 1-1.04, p = 0.009) and hemoglobin (HR = 0.70, CI = 0.55-0.89, p = 0.003). Conclusion: The median overall survival of positive EGFR mutation NSCLC patients treated with TKI was 9.3 months. An association was found between a younger age and an a higher hemoglobin level with a longer survival.
