Few predictive models aimed at predicting the presence of lymph node invasion (LNI) in patients with prostate cancer (PCa) treated with extended pelvic lymph node dissection (ePLND) are available to date. ⋯ We report the first update of a nomogram predicting the presence of LNI in patients treated with ePLND. The nomogram maintained high accuracy, even in more contemporary patients (87.6%). Because percentage of positive cores represents the foremost predictor of LNI, its inclusion should be mandatory in any LNI prediction model. Based on our model, those patients with a LNI risk<5% might be safely spared ePLND.

With the increasing use of laparoscopic and robotic radical cystectomy (RC), there are perceived concerns about the adequacy of lymph node dissection (LND). ⋯ High extended PLND during laparoscopic or robotic RC is technically feasible. Longer survival data in a larger cohort of patients are necessary to determine the proper place for robotic and laparoscopic surgery in patients undergoing RC for high-risk bladder cancer.

Prostate cancer screening is highly controversial, including the age to begin prostate-specific antigen (PSA) testing. Several studies have evaluated the usefulness of baseline PSA measurements at a young age. ⋯ Baseline PSA measurements at a young age are significant predictors of later prostate cancer diagnosis and disease-specific outcomes. Thus baseline PSA testing may be used for risk stratification and to guide screening protocols.

Prostate cancer (PCa) patients have many options within the realms of surgery or radiation therapy (RT). Technical advancements in RT planning and delivery have yielded different approaches, such as external beam, brachytherapy, and newer approaches such as image-guided tomotherapy or volumetric-modulated arc therapy. The selection of the optimal RT treatment for the individual is still a point of discussion, and the debate centres on two important outcomes-namely, cancer control and reduction of side-effects. ⋯ In the future, further improvement in RT planning and delivery will decrease side-effects and permit administration of higher doses. Related to the anatomy of the prostate, these higher doses may favour rectal sparing while not readily sparing the urethra and bladder neck. As a consequence, there may be a future shift from dose-limiting long-term rectal morbidity towards long-term urinary morbidity. In the absence of prospective randomised trials comparing different types of surgical and RT-based treatments in PCa, the introduction of validated tools for reporting functional and clinical outcomes is crucial for evaluating and identifying each individual's best treatment choice.
