PURPOSE To generate and present survey results on important issues relevant to treatment and follow-up of localized and locally advanced, high-risk prostate cancer (PCa) focusing on developing countries. METHODS A panel of 99 PCa experts developed more than 300 survey questions of which 67 questions concern the main areas of interest of this article: treatment and follow-up of localized and locally advanced, high-risk PCa in developing countries. A larger panel of 99 international multidisciplinary cancer experts voted on these questions to create the recommendations for treatment and follow-up of localized and locally advanced, high-risk PCa in areas of limited resources discussed in this article. RESULTS The panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer. These answers are based on panelist opinion and not on a literature review or meta-analysis. For questions that refer to an area of limited resources, the recommendations considered cost-effectiveness as well as the possible therapies with easier and greater access. Each question had five to seven relevant answers including two nonanswers. Results were tabulated in real time. CONCLUSION The voting results and recommendations presented in this article can guide physicians managing localized and locally advanced, high-risk PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for treatment of localized and locally advanced, high-risk PCa in developing countries have not been defined, this article will serve as a point of reference when confronted with this disease.

Abstract Introduction: While early radiotherapy (eRT) after radical prostatectomy (RP) has shown to improve oncologic outcomes in patients with high-risk prostate cancer (PCa) in a recent clinical trial, controversy remains regarding its benefit. We aimed to illustrate national trends of post-RP radiotherapy and compare outcomes and toxicities in patients receiving eRT vs. observation with or without late radiotherapy (lRT). Methods: Utilizing the Surveillance, Epidemiology and End Results (SEER)-Medicare data from 2001 to 2011, we identified 7557 patients with high-risk pathologic features after RP (≥ pT3N0 and/or positive surgical margins). Our study cohort was consisted of patients receiving RT within 6 months of surgery (eRT), those receiving RT after 6 months (IRT), and those never receiving RT (observation). Another subcohort, delayed RT (dRT), encompassed both IRT and observation. Trends of post-RP radiotherapy were compared using the Cochran-Armitage trend test. Cox regression models identified factors predictive of worse survival outcomes. Kaplan-Meier analyses compared the eRT and the dRT groups. Results: Among those with pathologically confirmed high-risk PCa after RP, 12.7% (n=959), 13.2% (n=1710), and 74.1% (n=4888) underwent eRT, lRT, and observation without RT, respectively. Of these strategies, the proportion of men on observation without RT increased significantly over time (p=0.004). Multivariable Cox regression model demonstrated similar outcomes between the eRT and the dRT groups. At a median follow up of 5.9 years, five-year overall and cancer-specific survival outcomes were more favorable in the dRT group, when compared to the eRT group. Radiation related toxicities, including urinary incontinence, erectile dysfunction, and urethral stricture, were higher in the eRT group when compared to the lRT group. Conclusions: Our results suggest that a blanket adoption of the eRT in high-risk PCa based on clinical trials with limited follow up may result in overtreatment of a significant number of men and expose them to unnecessary radiation toxicity.

PURPOSE To present a summary of the treatment and follow-up recommendations for the biochemical recurrence in castration-sensitive prostate cancer (PCa) acquired through a questionnaire administered to 99 PCa experts from developing countries during the Prostate Cancer Consensus Conference for Developing Countries. METHODS A total of 27 questions were identified as related to this topic from more than 300 questions. The clinician's responses were tallied and presented in a percentage format. Topics included the use of imaging for staging biochemical recurrence, treatment recommendations for three different clinical scenarios, the field of radiation recommended, and follow-up. Each question had 5-7 relevant response options, including “abstain” and/or “unqualified to answer,” and investigated not only recommendations but also if a limitation in resources would change the recommendation. RESULTS For most questions, a clear majority (> 50%) of clinicians agreed on a recommended treatment for imaging, treatment scenarios, and follow-up, although only a few topics reached a consensus > 75%. Limited resources did affect several areas of treatment, although in many cases, they reinforced more stringent criteria for treatment such as prostate-specific antigen values > 0.2 ng/mL and STAMPEDE inclusion criteria as a basis for recommending treatment. CONCLUSION A majority of clinicians working in developing countries with limited resources use similar cutoff points and selection criteria to manage patients treated for biochemically recurrent castration-sensitive PCa.
