Carcinoembryonic antigen and human chorionic gonadotrophin in breast carcinoma and prostatic specific acid phosphatase in prostate carcinoma.

ABSTRACT

Tumour markers viz carcinoembryonic antigen (CEA), human chorionic gonadotrophin (HCG) in 30 cases of carcinoma breast and prostatic specific acid phosphatase (PSAP) in 30 cases of carcinoma prostate were studied by peroxidase antiperoxidase technique in paraffin blocks of tissue. Twenty three (76.7%) and 20 (66.7%) cases were positive for CEA and HCG respectively. No correlation was observed between CEA and HCG status, and histological differentiation of the tumours. All the 29 cases (100%) of adenocarcinoma prostate were PSAP positive while a single case, negative for PSAP, was of transitional cell carcinoma.
