Consensus on diagnosis and management of non-metastatic castration resistant prostate cancer in Brazil: focus on patient, selection, treatment efficacy, side effects and physician's perception according to patient comorbidities

Background: Non-metastatic castration resistant prostate cancer (MO CRPC) has seen important developments in drugs and diagnostic tools in the last two years. New hormonal agents have demonstrated improvement in metastasis free survival in MO CRPC patients and have been approved by regulatory agencies in Brazil. Additionally, newer and more sensitive imaging tools are able to detect metastasis earlier than before, which will impact the percentage of patients staged as MO CRPC. Based on the available international guidelines, a group of Brazilian urology and medical oncologyexperts developed and completed a survey on the diagnosis and treatment of MO CRPC in Brazil. These results are reviewed and summarized and associated recommendations are provided. Objective: To present survey results on management of MO CRPC in Brazil. Design, setting, and participants: A panel of six Brazilian prostate cancer experts determined 64 questions concerning the main areas of interest: 1) staging tools, 2) treatments, 3) side effects of systemic treatment/s, and 4) osteoclast-targeted therapy. A larger panel of 28 Brazilian prostate cancer experts answered these questions in order to create country-specific recommendations discussed in this manuscript. Outcome measurements and statistical analysis: The panel voted publicly but anonymously on the predefined questions. These answers are the panelists' opinions, not a literature review or meta-analysis. Therapies not yet approved in Brazil were excluded from answer options. Each question had five to seven relevant answers including two non-answers. Results were tabulated in real time. Conclusions: The results and recommendations presented can be used by Brazilian physicians to support the management of MO CRPC patients. Individual clinical decision making should be supported by available data, however, for Brazil, guidelines for diagnosis and management of MO CRPC patients have not been developed. This document will serve as a point of reference when confronting this disease stage.

Automated summary

Brazilian experts conducted a survey on the management of non-metastatic castration resistant prostate cancer (MO CRPC) and provided relevant recommendations in this field. The results and recommendations can be used by Brazilian physicians to support the management of MO CRPC patients, serving as a reference point for dealing with this disease stage.
