Elution of cell-bound anti-prostatic epithelial antibodies after multiple cryotherapy of carcinoma of the prostate

Antibodies reactive with the cytoplasmic membrane or intercellular areas of autologous human and monkey prostatic secretory epithelial cells have been demonstrated by immunofluorescence in an eluate prepared from prostatic tissue obtained from a patient with metastatic adenocarcinoma of the prostate (CaP) after multiple cryotherapy of his primary prostatic tumour. While limited to the study of one patient, elution of anti-prostatic antibodies offers further documentation to previous studies pointing toward the participation of immunologic processes in CaP.
