TRK fusion proteins: oncogenic drivers in a variety of tumors across adult and pediatric cancers

TRK fusion proteins are oncogenic drivers that occur in a broad range of tumor types with varying frequency and across both pediatric and adult patients.1,2

Estimated frequency of NTRK gene fusion in specific tumor types

TRK fusion proteins


Frequencies reported from isolated studies that used variable methodologies to detect these genetic alterations.

a Papillary thyroid carcinoma.2,5
b Lung adenocarcinoma that did not contain other common oncogenic alterations.2,7
