Roach's Mathematical Equations in Predicting Pathological Stage in Men with Clinically Localized Prostate Cancer

Abstract

The equations represent a practical and effective instrument for preoperative clinical staging in patients with localized prostate cancer. By means of these mathematical formulas, one can assess the correct prognosis and--above all--plan the best therapeutic approach.

Predicting the Risk of Pelvic Node Involvement in Men With Prostate Cancer in the Contemporary Era: Change You Can Believe?: In Regard to Yu, et al. (Int J Radiat Oncol Biol Phys in Press)

“…Since then, three updates of the Partin nomograms have been published (3)(4)(5), necessitated by significant stage migration (6). As more patients present with early stage disease, the prediction of lymph node involvement requires a tool with more precision within this group.…”

“…As more patients present with early stage disease, the prediction of lymph node involvement requires a tool with more precision within this group. Therefore, although Hayes et al express concern that we exclude cT3 disease and prostate-specific antigen (PSA) values .26, they highlight an important point: in the era of Radiation Therapy Oncology Group 9413 and the RF, these findings were more commonplace (5-6% of patients) (3,6), whereas in the contemporary era, these findings are so rare that the most recent version of the Partin tables excludes these patients (3). Our approach is therefore consistent with that employed in these revised Partin tables.…”
