ABSTRACT
Introduction: Lung cancer is one of the main health problems in Cuba and worldwide. Genetic differences due to single nucleotide polymorphisms are important factors involved in the genetic susceptibility to this disease. In Cuba, there are scarce data available on single nucleotide polymorphisms and their possible influence on the incidence and prognosis of cancer.Objective: To expose the importance of the study of single nucleotide polymorphisms in DNA damage repair genes in lung cancer.
Results: Smoking is the main risk factor for developing lung cancer, however, approximately 15 % of smokers will develop the disease. Single nucleotide polymorphisms are important factors involved in genetic predisposition to diseases. The presence of polymorphic variants can modify the efficacy of repair systems, favoring the occurrence of genotoxicity and/or mutagenesis. They can also modify the response to oncological treatments and patient´s survival. Therefore, in addition to being susceptibility markers, polymorphisms are considered individual prognostic markers of response to therapy. This work emphasizes the usefulness of evaluating single nucleotide polymorphisms as clinical and susceptibility biomarkers in the Cuban population.
Conclusions. The study of single nucleotide polymorphisms will allow a personalized approach to oncological diseases, which could contribute to define groups of individuals at high risk of getting lung cancer, therefore, early disease detection.
