FOXA1 is a highly sensitive diagnostic marker for prostate cancer including small cell carcinoma of the prostate

Histopathology, EarlyView.
FOXA1 is a highly sensitive diagnostic marker for prostate cancer. Besides prostatic adenocarcinoma, it is also expressed in 57%–80% of metastatic or primary prostatic small cell carcinomas, which lose traditional prostatic markers including NKX3.1. Although it is less specific than NKX3.1, it can serve as a valuable adjunct for confirming prostatic ...
