Clinical studies of prostatic cancer imaging with radiolabeled antibodies against prostatic acid phosphatase

Conventional antibodies against prostatic acid phosphatase, labeled with iodine-131, have been administered to patients with prostatic carcinoma for the external scintigraphic imaging of tumors containing prostatic acid phosphatase (radioimmunodetection). The method has been found to be safe and reliable for imaging of primary tumors and non-bone metastases, even differentiating between lung tumors of prostatic and pulmonary origin.
