Abstract

Introduction: Lung cancer epidemiology focuses on understanding the distribution, causes, and consequences of this disease.

Objective: The study aimed to analyze how staging, radiotherapy, and chemotherapy are related to the survival of lung cancer patients in the population of Tulcan during the period 2021-2022.

Methods: The study corresponded to the predictive level and was observational, retrospective, and longitudinal. The population was 64 patients with lung cancer in a hospital in Tulcán, Ecuador. Cox regression analysis was performed.

Results: Of the 64 patients, 27 (42.2 %) died and 57.8 % (N=37) did not. Goodness-of-fit tests for the Cox regression model showed that the model was adequate, and the exogenous variables did not have a significant impact on the model fit. Chemotherapy was the only variable that was statistically significant in the model. Conclusions: Although exogenous variables did not significantly influence the Cox regression model, chemotherapy emerged as an important factor in improving patient survival. These findings suggest the importance of considering chemotherapy as an integral part of treatment for patients with lung cancer and underscore the need for further research to better understand its impact in different patient subgroups.
