Oncological control following partial gland ablation for intermediate-risk prostate cancer.

Oncological control following partial gland ablation for intermediate-risk prostate cancer. Urol Oncol. 2020 May 30;: Authors: Becher E, Lepor H Abstract Historically, the primary objection to partial gland ablation (PGA) for management of prostate cancer (CaP) has been disease multifocality and inability to localize significant disease. Improved disease localization and risk stratification with multiparametric magnetic resonance imaging and targeted biopsy, along with its minimal adverse impact on quality of life has enabled PGA to gain acceptance. Today, the primary barrier for adopting PGA is its unknown oncological outcomes. Objectives of this review are to provide a rationale for PGA for managing intermediate-risk (IR) CaP; review oncological outcomes following PGA for IR disease; and assess whether there is adequate data to justify PGA for management of IR CaP. There is no consensus how to assess or define oncological outcomes following PGA. We propose the following definitions for oncological outcomes: Oncological control (detection of any cancer following biopsy), oncological failure (detection of Gleason grade group >1 on follow-up biopsy), and oncological treatment failure (any disease that precipitate salvage treatment). There are only 3 reports in the literature where inclusion criteria specified pretreatment targeted biopsy and reflex prostate biopsy within 1 year of PGA in cohorts of men where >50% had Gleason gra...
