Evolution, controversies and the future of prostate cancer grading.

Pathol Int 2019 Feb 29;69(2):55-66. Epub 2019 Jan 29.

Aquesta Uropathology and University of Queensland, Brisbane, Queensland, Australia.

Histological grading of prostate cancer is one of the most important tissue-based parameters for prediction of outcome and treatment response. Gleason grading remains the foundation of prostate cancer grading, but has undergone a series of changes in the past 30 years, often initiated by consensus conference decisions. This review summarizes the most important modifications that were introduced by the 2005 and 2014 International Society of Urological Pathology (ISUP) revisions of Gleason grading and discusses the impact that these have had on current grading practices.

Current controversies on the role of lymphadenectomy for prostate cancer.

Urol Oncol 2019 03 19;37(3):219-226. Epub 2018 Dec 19.

The Smith Institute for Urology, Zucker School of Medicine Hofstra/Northwell, New Hyde Park, NY. Electronic address:

Lymph node dissection is part of the standard treatment protocol for various cancers, but its role in prostate cancer has been debatable for some time. Pelvic lymphadenectomy has been shown to better help stage prostate cancer patients, but has yet to be definitively proven to be of any benefit for survival. Various templates for lymph node dissections exist, and though some national guidelines have endorsed an extended pelvic node dissection, the choice of template is still controversial. Read More

Concomitant bladder cancer and prostate cancer: challenges and controversies.

Nat Rev Urol 2017 Oct 16;14(10):620-629. Epub 2017 Aug 16.

Institute of Pathological Anatomy and Histopathology, Polytechnic University of the Marche Region (Ancona), School of Medicine, United Hospitals, Via Conca 71, 60126 Torrette, Ancona, Italy.

Radical cystoprostatectomy (RCP) followed by bilateral pelvic lymphadenectomy and urinary diversion remains the gold-standard therapy for men with localized muscle-invasive bladder cancer (MIBC). Prostate cancer might be incidentally detected at the time of RCP with a reported prevalence of 24-51%. Typically, these patients are considered to have clinically insignificant disease, but data from emerging series challenge this assumption and suggest that some of these tumours might be aggressive, or somehow increase the aggressiveness of the associated MIBC, and can negatively influence the patient's overall survival outcomes.
