Current Clinical Applications of the In-capromab Pendetide Scan (ProstaScint(R) Scan, Cyt-356).

Prostate-specific antigen (PSA) has been extremely helpful in the detection of new or recurrent prostate cancer. However, localization of the recurrent tumor has been challenging with currently available radiographic modalities. The (111)In-capromab pendetide scan was developed to diagnose accurately and, more importantly, localize and stage a new or recurrent prostate cancer. Studies suggest that the (111)In-capromab pendetide scan can provide more accurate staging of clinically localized prostate cancer prior to staging lymphadenectomy or definitive therapy. It can also provide valuable information when local adjuvant radiation therapy is considered in men with biochemical cancer recurrence following radical prostatectomy.
