Is a standard definition of disease freedom needed for prostate cancer : undetectable prostate specific antigen compared with the American Society of Therapeutic Radiology and Oncology consensus definition?
The definition of freedom from prostate cancer significantly affects treatment results. A standard definition is needed and a PSA cutoff of 0.2 ng./ml. is suggested as the standard for all curative treatments for localized prostate cancer.
Proportion of MED & C-C may provide useful prognostic information about patients with moderately-differentiated, Gleason sum 5-7, prostate cancer treated with androgen-withdrawal endocrine therapy.
