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.
