ALK gene rearrangement status in non-squamous non-small cell lung carcinoma in the Middle Eastern population.

Background: Worldwide, the frequency of ALK rearrangement ranges between 3-6%, however its prevalence in the Middle Eastern population has not been reported. The aim of this study is to determine the frequency of the ALK rearrangement, as well as the clinico-pathologic characteristics of Lebanese patients with ALK-rearranged lung adenocarcinoma.

Methods: 152 patients diagnosed with non-squamous non-small cell lung carcinomas (NSCLC), at Hôtel-Dieu de France University Hospital between February 2014 and July 2016, were included in the study.
