TrkB-Pathway Prostate Panel (BDNF/TrkB/p75 IHC tissue test)

A standardized immunohistochemistry panel measuring BDNF, TrkB, and p75 in prostate biopsy or prostatectomy tissue, returning a 'TrkB-pathway activity score' that flags prostate cancers running a neurotrophin-driven growth program for closer management and pathway-targeted trial referral.
