[Endorectal Doppler echography of prostate cancer. Potential role in therapeutic evaluation. A case report]

The use of serial transrectal duplex sonography of the prostate in a patient treated for prostatic carcinoma is reported. Pre-treatment transrectal duplex sonography revealed abnormal Doppler signals in the prostate. After multiple-agent chemotherapy and bilateral orchiectomy, the prostate volume decreased by 65% and no abnormal Doppler signal could be recorded. Transrectal Doppler sonography of the prostate is expected to provide additional, original data on the response of prostatic tumors to endocrine manipulation or chemotherapy.
