ALK translocation renal cell carcinoma, also ALK-rearranged renal cell carcinoma and ALK-positive renal cell carcinoma, is a type of renal cell carcinoma recognized by the WHO.

General

  • Extremely rare.
    • One case was identified in 829 consecutively screened Korean patients.[1]
    • A second series described 8 in 276 cases on a microarray.[2]
    • In 2016, less than 17 cases reported.[3]
  • May respond to ALK inhibitors such as alectinib[4] or crizotinib.[3]
