Abstract :

Introduction In Ecuador, lung cancer ranks eighth in men and ninth in women. The objective of the present investigation is to determine in a descriptive analysis a relationship between EGFR mutation and laterality. Methods 37 histopathological samples were analyzed during the years 2015–2016 using descriptive analysis of frequency as well as crossing of variables. Results Of the 37 patients, EGFR mutation could be determined in 18 samples (48.6%) while 19 did not present a mutation (51.4%) with a distribution of pulmonary lobes with a certain predisposition to be found in the upper lobes and in the right lung. Conclusion The distribution of lung cancer in our research is similar to that demonstrated in international studies in which right lung cancer occurs more frequently than the left one, as well as the upper lobe above the lower one, having to recommend that we should start prospective studies and evaluate survival according to laterality.
