Summary
Brief summary (as posted)
Because ALK-positive lung cancer constitutes less than 5% of all lung cancers, it is critically important to select those patients who are more likely to have the ALK mutation. Clinical characteristics of patients with mutations in the target gene should also be known, so that the incidence of a given target mutation is established in a specific population. There is not incidence known in Mexican population, but it is believed it is greater.

- ALK-BREAK APART
- description
- We reviewed 230 consecutive cases of NSCLC that were retrieved from oncologic molecular laboratory and diagnostic pathology unit at the Instituto Nacional de Cancerologia, Mexico city, between 2011 and 2014. Samples were sent to the unit of pathological anatomy, a Pathologist confirmed the histologic diagnosis. The only inclusion criterion was the availability of tissue for biomarker studies. Clinical and pathologic details of these patients were included in a database, obtained from medical records. For ALK fusion testing, we applied dual-color, break-apart FISH, RT-qPCR, and immunohistochemistry. Interpretation of the results was done in double-blind manner without knowing the results by other methods.
