Summary

The ability of genomic biomarkers to Measuring tumour aggressiveness, and facilitate the selection of therapies in patients who had salvage radical prostatectomy after focal therapy and predict the risk of biochemical recurrence BCR after focal therapy or RP.

Detailed description

Between 2007 and 2017, 30 patients underwent salvage radical prostatectomy SRP for recurrent localized PCa at our institution (Institute Mutual Montsouris). Primary radiotherapy, brachytherapy and whole-gland treatments were excluded, as to evaluate the true spectrum of morphologic changes caused by the focal emerging ablative modalities. Thirteen SRP after focal ablative therapies FAT (cryotherapy or high intensity focused ultrasound- HIFU or vascular-targeted photodynamic therapy- VTP) were identified from our prospective collected database. Genitourinary pathologists were provided clinical information related to prior therapies and immunohistochemical (IHC) markers were used in the diagnosis of limited primary PC on needle biopsy when necessary. Prostatectomy specimens were processed and the number of tumor foci, size of the dominant focus and pathological stage were recorded. Residual disease was graded according to the Gleason grading system. Treatment-related histologic changes were examined.
