BACKGROUND AND OBJECTIVE/OBJECTIVE:As most Prostate Imaging Reporting and Data System (PI-RADS) 5 lesions on MRI harbor Gleason grade (GG) group ≥2 disease on biopsy, optimal management of patients with imaging-biopsy discordance remains unclear. To estimate grade misclassification, we evaluated the incidence of Gleason upgrading among patients with GG1 disease in the setting of a PI-RADS 5 lesion. METHODS:We conducted a single-institution retrospective analysis to identify patients with GG1 prostate cancer on fusion biopsy with MRI demonstrating ≥1 PI-RADS 5 lesion. Primary study outcome was identification of ≥GG2 disease on subsequent active surveillance (AS) biopsy or radical prostatectomy (RP). We used multivariable models to examine factors associated with reclassification. RESULTS:We identified 110 patients with GG1 disease on initial biopsy and ≥1 PI-RADS 5 lesion. There were 104 patients (94.6%) initially managed with AS and 6 (5.5%) received treatment. Sixty-one patients (58.7%) on AS underwent additional biopsies. Of these, 43 (70.5%) patients had tumor upgrading, with 32 (74.4%) upgraded on first surveillance biopsy. Forty-four (40%) patients ultimately received treatment, including prostatectomy in 15 (13.6%) and radiation in 25 (22.7%). Two patients (1.8%) developed metastases. In multivariable models, genomic classifier score was associated with upgrading. Limitations include a lack of multi-institutional data and long-term outcomes data. CONCLUSIONS:Most patients diagnosed with GG1 prostate cancer on MRI-Ultrasound fusion biopsy in the setting of a PI-RADS 5 lesion were found to have ≥GG2 disease on subsequent tissue sampling, suggesting substantial initial misclassification and reinforcing the need for confirmatory testing.

Loeb, Stacy; Cheng, Heather H; Paller, Channing J; Weg, Emily; Johnson, Jennifer; Gross, Laura; Keith, Scott W; Russo, Jessica; Hathaway, Feighanne; Rivera, Adrian; Giri, Veda N
BACKGROUND:Germline testing is important in prostate cancer and evaluation can be complex. METHODS:We instituted a monthly multi-disciplinary virtual genetics tumor board (7/2021-3/2022). Participants and panelists were surveyed on usefulness and acceptability. RESULTS:101 participants attended a session, and 77 follow-up surveys were completed. Over 90% participants and 100% panelists endorsed usefulness of the case discussions and usability of the technology. The majority felt it provided new information they will use. CONCLUSIONS:A multidisciplinary genetics board was successfully developed to address complexity in prostate cancer genetics. The virtual platform may enhance dissemination of expertise where there are regional gaps.

Artificial intelligence and patient education
Paluszek, Olivia; Loeb, Stacy
PURPOSE OF REVIEW/OBJECTIVE:Artificial intelligence (AI) chatbots are increasingly used as a source of information. Our objective was to review the literature on their use for patient education in urology. RECENT FINDINGS/RESULTS:There are many published studies examining the quality of AI chatbots, most commonly ChatGPT. In many studies, responses from chatbots had acceptable accuracy but were written at a difficult reading level without specific prompts to enhance readability. A few studies have examined AI chatbots for other types of patient education, such as creating lay summaries of research publications or generating handouts. SUMMARY/CONCLUSIONS:Artificial intelligence chatbots may provide an adjunctive source of patient education in the future, particularly if prompted to provide results with better readability. In addition, they may be used to rapidly generate lay research summaries, leaflets or other patient education materials for final review by experts.

BACKGROUND AND OBJECTIVE/OBJECTIVE:Innovations have improved outcomes in advanced prostate cancer (PC). Nonetheless, we continue to lack high-level evidence on a variety of topics that greatly impact daily practice. The 2024 Advanced Prostate Cancer Consensus Conference (APCCC) surveyed experts on key questions in clinical management in order to supplement evidence-based guidelines. Here we present voting results for questions from APCCC 2024. METHODS:Before the conference, a panel of 120 international PC experts used a modified Delphi process to develop 183 multiple-choice consensus questions on eight different topics. Before the conference, these questions were administered via a web-based survey to the voting panel members ("panellists"). KEY FINDINGS AND LIMITATIONS/UNASSIGNED:Consensus was a priori defined as ≥75% agreement, with strong consensus defined as ≥90% agreement. The voting results show varying degrees of consensus, as discussed in this article and detailed in the Supplementary material. These findings do not include a formal literature review or meta-analysis. CONCLUSIONS AND CLINICAL IMPLICATIONS/CONCLUSIONS:The voting results can help physicians and patients navigate controversial areas of clinical management for which high-level evidence is scant or conflicting. The findings can also help funders and policymakers in prioritising areas for future research. Diagnostic and treatment decisions should always be individualised on the basis of patient and cancer characteristics, and should incorporate current and emerging clinical evidence, guidelines, and logistic and economic factors. Enrolment in clinical trials is always strongly encouraged. Importantly, APCCC 2024 once again identified important gaps (areas of nonconsensus) that merit evaluation in specifically designed trials.

Urology on a changing planet: links between climate change and urological disease
Cole, Alexander P; Qian, Zhiyu; Gupta, Natasha; Leapman, Michael; Zurl, Hanna; Trinh, Quoc-Dien; Sherman, Jodi D; Loeb, Stacy; Iyer, Hari S
Urological diseases and their varied forms of management warrant special attention in the setting of climate change. Regarding urological cancers, climate change will probably increase the incidence and severity of cancer diagnoses through exposures to certain environmental risk factors, while simultaneously disrupting cancer care delivery and downstream outcomes. Regarding benign urological diseases, a burgeoning body of work exists on climate-related heat waves, dehydration, urolithiasis, renal injury and infectious and vector-borne diseases. Adding to the potential effect on disease pathogenesis, many patients with urological diseases undergo high-tech, resource-intensive interventions, such as robotic surgery, and entail intensive longitudinal assessments over many years. These features incur a considerable carbon footprint, generate substantial waste, and can introduce vulnerabilities to climate-related weather events. Links exist between planetary health (the health of humans and the natural systems that support our health), climate change and urological disease and urological care providers face many challenges in the era of anthropogenic climate change. The next steps and priorities for research, management, and health care delivery include identification and prioritization of health care delivery strategies to minimize waste and carbon emissions, while supporting climate resilience. Examples include supporting telemedicine, limiting low-value care, and building resilience to minimize impacts of climate-related disasters to prepare for the challenges ahead.

Phosphorus Content of Several Plant-Based Yogurts
Babich, John S; Patel, Jason; Dupuis, Léonie; Goldfarb, David S; Loeb, Stacy; Borin, James; Joshi, Shivam
OBJECTIVE:In people with chronic kidney disease (CKD), hyperphosphatemia is a risk factor for mortality. Though unproven, dietary phosphorus control is considered essential in CKD. Although dietary and serum phosphorus are correlated, phosphorus from plant foods rich in phytate is less bioavailable than from animal and processed foods. Yogurt, valued for its low phosphorus and high protein, may be detrimental in CKD due to animal protein content. Plant-based yogurts (PBYs) might offer similar benefits without the downsides of animal protein, but little is known about their phosphorus content. DESIGN AND METHODS/METHODS:Protein contents and phosphorus additives were gathered from nutrition labels of several PBYs, including almond, cashew, oat, coconut, and soy substrates. Phosphorus content was measured via emission spectrometry by Eurofins (Madison, WI), and the phosphorus-to-protein ratio (PPR) was calculated for each PBY. RESULTS:Phosphorus content was highest in Silk Soy Strawberry, Silk Almond Strawberry, and Siggi's Coconut Mixed Berries, while it was lowest in So Delicious Coconut Strawberry, Oatly Oat Strawberry, Forager Cashew Strawberry, and Kite Hill Almond Strawberry. Ingredient labels revealed that Silk Soy Strawberry, Silk Almond Strawberry, and Oatly Oat Strawberry contained phosphorus additives, and Siggi's Coconut Mixed Berries contained pea protein additives. Though from the same substrate class, So Delicious Coconut Strawberry and Siggi's Coconut Mixed Berries showed significant differences in phosphorus and protein contents. All seven PBYs had higher PPR ratios than dairy yogurts like Stonyfield Organic Oikos Strawberry, Chobani Nonfat Strawberry, and Yoplait Greek Strawberry. CONCLUSION/CONCLUSIONS:Low-PPR foods are important for CKD patients. Siggi's Coconut Mixed Berries had the lowest PPR, making it potentially the most desirable for CKD patients. However, there is high variability in PPR among PBYs with the same substrate; therefore, Delicious Coconut Strawberry had the highest PPR, highlighting the importance of product selection for patients with CKD.
