Prostatic Differentiation Markers - PSA is a cytoplasmic antigen believed to be present almost exclusively in prostatic glandular epithelium and carcinomas arising in the prostate. Antibodies to PSA mark the great majority ( 95%) of prostatic adenocarcinomas. Application of PSA is particularly useful in the separation of carcinomas of prostatic origin from those of transitional cell when this separation cannot be made on the basis of histologic features only.
A protein that serves as a marker for prostate cancer or benign prostatic hyperplasia. PSA levels can be used to help detect prostate cancer, to monitor its treatment, and to warn of possible recurrence.
