Defining Intermediate-Risk Prostate Cancer Suitable for Active Surveillance
Loeb, Stacy; Folkvaljon, Yasin; Bratt, Ola; Robinson, David; Stattin, Pär
PURPOSE/OBJECTIVE:Active surveillance (AS) for intermediate-risk prostate cancer (PCa) is controversial. Many AS programs are limited to grade group (GG) 1 (Gleason 6) and PSA<10 ng/ml. However, recent guidelines state that AS can be considered for limited GG2 (Gleason 3+4), despite limited data on outcomes. Our objective was to compare prostatectomy outcomes between subgroups of intermediate-risk versus low-risk PCa. METHODS:We performed an observational study in the National Prostate Cancer Register (NPCR) of Sweden, including 98% of PCa nationwide. From 2009-2012, 5087 men with low-risk (GG1, PSA<10, and ≤cT2) and intermediate-risk PCa (GG2 or PSA 10-20, or T2) underwent radical prostatectomy. We compared upgrading and upstaging between groups, based on the UCSF Cancer of the Prostate Risk Assessment (CAPRA) scores and published AS criteria. Results were validated in an independent dataset of cases diagnosed 2013-2016. RESULTS:Men with GG1, PSA 10-15ng/ml and PSA density <0.15 had no significant difference in upgrading and adverse pathology compared to low-risk PCa. PSA>15 or GG2 were associated with a significantly greater risk of aggressive PCa. Men with low-risk CAPRA scores (0-2) and GG2 had almost a 3-fold increased risk of upgrading and 2-fold increased risk of adverse pathology compared to low-risk CAPRA GG1. CONCLUSIONS:Expanding the PSA threshold to 15 ng/ml for GG1 PCa would allow more men to choose AS and is unlikely to compromise outcomes, particularly if PSA density is low. By contrast, caution should be exercised in offering AS to men with PSA>15 or GG2.

Borgmann, Hendrik; Cooperberg, Matthew; Murphy, Declan; Loeb, Stacy; N'Dow, James; Ribal, Maria Jose; Woo, Henry; Rouprêt, Morgan; Winterbottom, Andrew; Wijburg, Carl; Wirth, Manfred; Catto, James; Kutikov, Alexander
CONTEXT/BACKGROUND:Social media (SoMe) has transformed communication among health care professionals by enabling rapid and global information exchange. Yet, the novelty of SoMe and concerns about potential risks continue to be barriers to adoption. OBJECTIVE:To encourage appropriate professional use of SoMe by physicians in concordance with best practices and to update practical guidelines for effective and professional use of these communication technologies. EVIDENCE AQUISITION/UNASSIGNED:The European Association of Urology (EAU; @Uroweb) brought together a committee of SoMe stakeholders in the urology field. PubMed and the grey literature were searched to identify SoMe position papers by other medical societies and organizations. EVIDENCE SYNTHESIS/RESULTS:Updated practical guidelines for effective and professional use of SoMe communication technologies. A core of 10 practical recommendations for the responsible, ethical, and constructive use of SoMe communication technologies was articulated. The guidelines are limited by their inherent subjective nature and lack of robust evidence supporting their utility. CONCLUSIONS:SoMe is reshaping the way the urological care providers communicate; however, appropriate engagement requires courtesy, professionalism, and honesty. Adherence to guidelines will help users harness the benefits of SoMe in a safe and effective manner. PATIENT SUMMARY/UNASSIGNED:Social media has transformed communication among health care professionals. This narrative review article provides an update of practical guidelines for effective and professional use of these communication technologies.

Prostate cancer and social media
Loeb, Stacy; Katz, Matthew S; Langford, Aisha; Byrne, Nataliya; Ciprut, Shannon
The use of social media is increasing globally and is employed in a variety of ways in the prostate cancer community. In addition to their use in research, advocacy, and awareness campaigns, social media offer vast opportunities for education and networking for patients with prostate cancer and health-care professionals, and many educational resources and support networks are available to patients with prostate cancer and their caregivers. Despite the considerable potential for social media to be employed in the field of prostate cancer, concerns remain - particularly regarding the maintenance of patient confidentiality, variable information quality, and possible financial conflicts of interest. A number of professional societies have, therefore, issued guidance regarding social media use in medicine. Social media are used extensively in other cancer communities, particularly among patients with breast cancer, and both the quantity and type of information available are expected to grow in the future.

A Multi-Institutional Prospective Trial Confirms Noninvasive Blood Test Maintains Predictive Value in African American Men
Punnen, Sanoj; Freedland, Stephen J; Polascik, Thomas J; Loeb, Stacy; Risk, Michael C; Savage, Stephen; Mathur, Sharad C; Uchio, Edward; Dong, Yan; Silberstein, Jonathan L
PURPOSE/OBJECTIVE:The 4Kscore® test accurately detects aggressive prostate cancer and reduces unnecessary biopsies. However, its performance in African American men has been unknown. We assessed test performance in a cohort of men with a large African American representation. MATERIALS AND METHODS/METHODS:Men referred for prostate biopsy at 8 Veterans Affairs medical centers were prospectively enrolled in the study. All men underwent phlebotomy for 4Kscore test assessment prior to prostate biopsy. The primary outcome was the detection of Grade Group 2 or higher cancer on biopsy. We assessed the discrimination, calibration and clinical usefulness of 4Kscore to predict Grade Group 2 or higher prostate cancer and compared it to a base model consisting of age, digital rectal examination and prostate specific antigen. Additionally, we compared test performance in African American and nonAfrican American men. RESULTS:Of the 366 enrolled men 205 (56%) were African American and 131 (36%) had Grade Group 2 or higher prostate cancer. The 4Kscore test showed better discrimination (AUC 0.81 vs 0.74, p <0.01) and higher clinical usefulness on decision curve analysis than the base model. Test prediction closely approximated the observed risk of Grade Group 2 or higher prostate cancer. There was no difference in test performance in African American and nonAfrican American men (0.80 vs 0.84, p = 0.32), The test outperformed the base model in each group. CONCLUSIONS:The 4Kscore test accurately predicts aggressive prostate cancer for biopsy decision making in African American and nonAfrican American men.

Health state utilities among contemporary prostate cancer patients on active surveillance
Loeb, Stacy; Curnyn, Caitlin; Walter, Dawn; Fagerlin, Angela; Siebert, Uwe; Mühlberger, Nick; Braithwaite, R Scott; Schwartz, Mark D; Lepor, Herbert; Sedlander, Erica
Background/UNASSIGNED:Active surveillance (AS) is the most rapidly expanding management option for favorable-risk prostate cancer (PCa). Early studies suggested substantial decrements in utility (quality of life weights) from disease-related anxiety. Our objective was to determine utilities for contemporary AS patients using different instruments. Methods/UNASSIGNED:We performed a systematic review of PubMed, PMC and OVID for utility measurements in modern AS patients. We then examined utilities among 37 men on AS participating in focus groups between 2015-2016 using the generic EurQol five dimensions questionnaire (EQ-5D-3L) and Patient Oriented Prostate Utility Scale (PORPUS), a PCa-specific instrument. Results/UNASSIGNED:The systematic review found previous studies with utilities for PCa treatment and historical watchful waiting populations, but none specifically in contemporary AS. In our AS population, the mean EQ-5D-3L score was 0.90±0.16 (median, 1.00; range, 0.21-1.00) and PORPUS was 0.98±0.03 (median, 0.99; range, 0.84-1.00). The Spearman correlation between the EQ-5D-3L and PORPUS was 0.87 (P<0.0001), and 38% of patients had a difference >0.1 between instruments. Conclusions/UNASSIGNED:Most contemporary AS patients had high utility scores suggesting that they perceive themselves in good health without a major decrement in quality of life from the disease. However, some patients had substantial differences in utility measured with generic versus disease-specific instruments. Further study is warranted into the optimal instrument for utility assessment in contemporary AS patients.

Purpose It is clinically challenging to integrate genomic-classifier results that report a numeric risk of recurrence into treatment recommendations for localized prostate cancer, which are founded in the framework of risk groups. We aimed to develop a novel clinical-genomic risk grouping system that can readily be incorporated into treatment guidelines for localized prostate cancer. Materials and Methods Two multicenter cohorts (n = 991) were used for training and validation of the clinical-genomic risk groups, and two additional cohorts (n = 5,937) were used for reclassification analyses. Competing risks analysis was used to estimate the risk of distant metastasis. Time-dependent c-indices were constructed to compare clinicopathologic risk models with the clinical-genomic risk groups. Results With a median follow-up of 8 years for patients in the training cohort, 10-year distant metastasis rates for National Comprehensive Cancer Network (NCCN) low, favorable-intermediate, unfavorable-intermediate, and high-risk were 7.3%, 9.2%, 38.0%, and 39.5%, respectively. In contrast, the three-tier clinical-genomic risk groups had 10-year distant metastasis rates of 3.5%, 29.4%, and 54.6%, for low-, intermediate-, and high-risk, respectively, which were consistent in the validation cohort (0%, 25.9%, and 55.2%, respectively). C-indices for the clinical-genomic risk grouping system (0.84; 95% CI, 0.61 to 0.93) were improved over NCCN (0.73; 95% CI, 0.60 to 0.86) and Cancer of the Prostate Risk Assessment (0.74; 95% CI, 0.65 to 0.84), and 30% of patients using NCCN low/intermediate/high would be reclassified by the new three-tier system and 67% of patients would be reclassified from NCCN six-tier (very-low- to very-high-risk) by the new six-tier system. Conclusion A commercially available genomic classifier in combination with standard clinicopathologic variables can generate a simple-to-use clinical-genomic risk grouping that more accurately identifies patients at low, intermediate, and high risk for metastasis and can be easily incorporated into current guidelines to better risk-stratify patients.
