every patient into the same basket. One risk with the
presented nomogram is that it includes androgen deprivation
therapy use as a factor
—
a subjective measure which is a
surrogate for other disease factors not measured in the
nomogram. Postoperative PSA velocity is not taken into
account. These patients come from a long-time period, much
of which was a different era in terms of the clinical risk
groups of patients undergoing prostatectomy. The study
offers valuable insight that not all men with a residual PSA
after prostatectomy require immediate additional treatment,
but they still require complex consideration of many
variables in making a recommendation for or against salvage
radiotherapy.
