Correlation of ROS1 (D4D6) Immunohistochemistry with ROS1 Fluorescence In Situ Hybridization Assay in a Contemporary Cohort of Pulmonary Adenocarcinomas. (PubMed, South Asian J Cancer)
Conclusion   ROS1 IHC has high sensitivity at a cost of lower specificity for the detection of ROS1 gene rearrangement. All IHC positive cases should undergo a confirmatory FISH test as this testing algorithm stands as a reliable and economic tool to screen ROS1 rearrangement in lung adenocarcinomas.

Different Prevalence of Molecular Alterations for Non-Small Cell Lung Cancer in Mexican Cohort of 200 Patients (USCAP 2022)
"Three differences of prevalence are observed in our study for mexican population with lung AC: EGFR 32.7%, 13.9% KRAS and ALK 6.7%. According to recent NGS studies in Mexico, EGFR has a prevalence of 36.7% and 20% for KRAS. In Mexico and Latin America (LA) the mutational frequency is inverse compared to Caucasian population, with KRAS (20-25%) being more frequent than EGFR (10-15%) and ALK (4.5-5%)."
