Abstract

ProstaScint® (CYT-356 or capromab pendetide, Cytogen) is an 111in-labeled monoclonal mouse antibody specific for prostate-specific membrane antigen, a prostate transmembrane glycoprotein that is upregulated in prostate adenocarcinoma. ProstaScint scans are US Food and Drug Administration approved for pretreatment evaluation of metastatic disease in high-risk patients. They are also approved for post-prostatectomy assessment of recurrent disease in patients with a rising prostate-specific antigen level. This review explores the literature on ProstaScint and its use in guiding the treatment of prostate cancer. A novel technique for identifying areas of cancer within the prostate using ProstaScint images fused with pelvic computed tomography scans is also described. The identification of areas of high antibody signal provides targets for radiotherapeutic dose escalation, with the overall goals of improving treatment outcome while preserving adjacent tissue structures and decreasing treatment morbidity.
