ABSTRACT Purpose: Prostate cancer (PCa) is the second most common oncologic disease among men. Radical treatment with curative intent provides good oncological results for PCa survivors, although definitive therapy is associated with significant number of serious side-effects. In modern-era of medicine tissue-sparing techniques, such as focal HIFU, have been proposed for PCa patients in order to provide cancer control equivalent to the standard-of-care procedures while reducing morbidities and complications. The aim of this systematic review was to summarise the available evidence about focal HIFU therapy as a primary treatment for localized PCa. Material and methods: We conducted a comprehensive literature review of focal HIFU therapy in the MEDLINE database (PROSPERO: CRD42021235581). Articles published in the English language between 2010 and 2020 with more than 50 patients were included. Results: Clinically significant in-field recurrence and out-of-field progression were detected to 22% and 29% PCa patients, respectively. Higher ISUP grade group, more positive cores at biopsy and bilateral disease were identified as the main risk factors for disease recurrence. The most common strategy for recurrence management was definitive therapy. Six months after focal HIFU therapy 98% of patients were totally continent and 80% of patients retained sufficient erections for sexual intercourse. The majority of complications presented in the early postoperative period and were classified as low-grade. Conclusions: This review highlights that focal HIFU therapy appears to be a safe procedure, while short-term cancer control rate is encouraging. Though, second-line treatment or active surveillance seems to be necessary in a significant number of patients.

ABSTRACT Purpose: To describe the use of endocavitary ultrasound probe as an auxiliary tool when performing partial nephrectomy in cases of endophytic renal tumors, to standardize the method, and to report the preliminary results achieved with this technique. Methods: Fifteen patients diagnosed with completely endophytic underwent partial nephrectomy with the use of an endocavitary ultrasound probe. This article describes the technique involved in partial nephrectomy and details the preparation of the endocavitary ultrasound probe to ensure its safe use. Results: All the patients had a RENAL score between 8 and 11. The median time of warm ischemia was 26 and 18 minutes for laparoscopic or robot-assisted surgery, respectively. The median duration of surgery was 150 minutes, and the median console time was 145 minutes for the laparoscopic and robot-assisted surgery groups, respectively. The median estimate of blood loss was 200 mL. Only three patients in the laparoscopic group had focal positive surgical margins. There were no cases of infection at the site of probe entry. Conclusions: Intraoperative use of an endocavitary ultrasound probe for partial nephrectomy is possible and a safe alternative to the excision of endophytic tumors when neither robotic probes nor laparoscopic probes are available.

ABSTRACT Introduction: The health-related QoL is a patient-centered evaluation covering several aspects. This evaluation seems to be particularly important in patients submitted to radical cystectomy (RC) and urinary diversion with ileal conduit (IC) or a neobladder (NB). Objective: Review all recent data comparing QoL outcomes after radical cystectomy with NB and IC diversions. Evidence Acquisition: A systematic search in PubMed/Medline, Embase, and Cochrane databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement in December 2018. All articles published from January 01, 2012 to December 31, 2018, were included. A study was considered relevant if it compared QoL outcomes using validated questionnaires (EORTC QLQ C30, FACT-G, FACT-BL, FACT-VCI, and BCI). Evidence Synthesis: In 11 included studies, a total of 1389 participants were accounted (730 NB and 659 IC cases). The studies were conducted in 8 different countries, two were prospective, and none was randomized. There were two studies favoring results with a neobladder, 3 with incontinent diversion and 6 with no differences. The EORTC-QLQ-C30 was the most used instrument (5 studies) followed by FACT VCI and BCI (3 studies each). Given the heterogeneity of data and lack of prospective studies, a meta-analysis was not performed. Conclusion: No superiority of one urinary diversion was characterized. It seems that the choice must be individualized with an extensive preoperative orientation of the patient and their relatives. That will probably influence how the patient accepts the new condition.

ABSTRACT Background Radical prostatectomy (RP) has been used as the main primary treatment for prostate cancer (PCa) for many years with excellent oncologic results. However, approximately 20-40% of those patients has failed to RP and presented biochemical recurrence (BCR). Prostatic specific antigen (PSA) has been the pivotal tool for recurrence diagnosis, but there is no consensus about the best PSA threshold to define BCR until this moment. The natural history of BCR after surgical procedure is highly variable, but it is important to distinguish biochemical and clinical recurrence and to find the correct timing to start multimodal treatment strategy. Also, it is important to understand the role of each clinical and pathological feature of prostate cancer in BCR, progression to metastatic disease and cancer specific mortality (CSM). Review design A simple review was made in Medline for articles written in English language about biochemical recurrence after radical prostatectomy. Objective To provide an updated assessment of BCR definition, its meaning, PCa natural history after BCR and the weight of each clinical/pathological feature and risk group classifications in BCR, metastatic disease and CSM.

ABSTRACT Introduction: Prostate cancer is one of the tumors with higher incidence and mortality among men in the World. Epidemiological data are influenced by life expectancy of population, available diagnostic methods, correct collection of data and quality of health services. Screening of the disease is not standardized around the World. Up till now there is no consensus about the risks versus benefits of early detection. There are still missing data about this pathology in Latin America. Objective: to revise current epidemiologic situation and early diagnosis policies of prostate cancer in Brazil and Latin America. Materials and Methods: Medline, Cochrane Library and SciELO databases were reviewed on the subject of epidemiology and screening of prostate cancer. Screening research was performed in websites on national public health organizations and Latin America. Screening recommendations were obtained from those governmental organizations and from Latin American urological societies and compared to the most prominent regulatory agencies and societies of specialists and generalists from around the World. Results: Brazil and Latin America have a special position in relation to incidence and mortality of prostate cancer. In Brazil, it occupies the first position regarding incidence of cancer in men and the second cause of mortality. Central America has the highest rate of mortality of the continent with lower incidence/mortality ratios. Screening recommendations are very distinct, mainly among regulatory organs and urological societies. Conclusion: prostate cancer epidemiology is an important health public topic. Data collection related to incidence and mortality is still precarious, especially in less developed countries. It is necessary to follow-up long term screening studies results in order to conclude its benefits.
