Barriers and facilitators of germline genetic evaluation for prostate cancer

Loeb, Stacy; Li, Randall; Sanchez Nolasco, Tatiana; Byrne, Nataliya; Cheng, Heather H; Becker, Daniel; Leader, Amy E; Giri, Veda N
BACKGROUND:Genetic counseling and germline testing have an increasingly important role for patients with prostate cancer (PCa); however, recent data suggests they are underutilized. Our objective was to perform a qualitative study of the barriers and facilitators of germline genetic evaluation among physicians who manage PCa. METHODS:We conducted semi-structured interviews with medical oncologists, radiation oncologists, and urologists from different U.S. practice settings until thematic saturation was achieved at n = 14. The interview guide was based on the Tailored Implementation in Chronic Diseases Framework to identify key determinants of practice. Interview transcripts were independently coded by ≥2 investigators using a constant comparative method. RESULTS:The decision to perform or refer for germline genetic evaluation is affected by factors at multiple levels. Although patient factors sometimes play a role, the dominant themes in the decision to conduct germline genetic evaluation were at the physician and organizational level. Physician knowledge, coordination of care, perceptions of the guidelines, and concerns about cost were most frequently discussed as the main factors affecting utilization of germline genetic evaluation. CONCLUSIONS:There are currently numerous barriers to implementation of germline genetic evaluation for PCa. Efforts to expand physician education, to develop tools to enhance genetics in practice, and to facilitate coordination of care surrounding genetic evaluation are important to promote guideline-concordant care.

An Evaluation of the Readability and Content-Quality of Pelvic Organ Prolapse YouTube Transcripts

Herbert, Amber S; Nemirovsky, Amy; Hess, Deborah S; Walter, Dawn; Abraham, Nitya E; Loeb, Stacy; Malik, Rena D
OBJECTIVE:To evaluate the readability, quality, and accuracy of pelvic organ prolapse (POP) YouTube transcripts. METHODS:We analyzed the readability of written transcripts for the first 100 YouTube videos about "Pelvic Organ Prolapse." Transcripts were excluded if they lacked narration in English or contained both no text and no audio. Readability was evaluated using an online software (www.readabilityformulas.com) to determine reading grade levels. The quality of videos was scored using the DISCERN quality criteria and the Patient Education Materials Assessment Tool. Accuracy was assessed by comparing content to accepted POP treatment guidelines. RESULTS:The median grade level of all 100 videos was 12.6. High quality transcripts or transcripts that discuss the benefits, risk, alternative treatments, and quality of life had a median readability score of 12.5. Transcripts with low misinformation (85%) had a higher median readability index (12.6), than transcripts containing high misinformation (12.2). More than 20% of transcripts discussed shared decision-making. The median readability index for videos with a high Patient Education Materials Assessment Tool score (>75%) for understandability and actionability were both 12.6. CONCLUSION/CONCLUSIONS:Transcripts of POP YouTube videos are written at difficult levels with many transcripts exceeding the reading capabilities of the American population. The majority of good transcripts or transcripts with high quality content, low misinformation, shared decision-making, no commercial bias, and understandable and actionable content were written at a high school level or above. Efforts should be made to avoid complex terms when creating patient focused content and helping patients navigate to content of appropriate literacy online.

Active Surveillance Strategies for Low-Grade Prostate Cancer: Comparative Benefits and Cost-effectiveness

Kang, Stella K; Mali, Rahul D; Prabhu, Vinay; Ferket, Bart S; Loeb, Stacy
Background Active surveillance (AS) is the recommended treatment option for low-risk prostate cancer (PC). Surveillance varies in MRI, frequency of follow-up, and the Prostate Imaging Reporting and Data System (PI-RADS) score that would repeat biopsy. Purpose To compare the effectiveness and cost-effectiveness of AS strategies for low-risk PC with versus without MRI. Materials and Methods This study developed a mathematical model to evaluate the cost-effectiveness of surveillance strategies in a simulation of men with a diagnosis of low-risk PC. The following strategies were compared: watchful waiting, prostate-specific antigen (PSA) and annual biopsy without MRI, and PSA testing and MRI with varied PI-RADS thresholds for biopsy. MRI strategies differed regarding scheduling and use of PI-RADS score of at least 3, or a PI-RADS score of at least 4 to indicate the need for biopsy. Life-years, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios were calculated by using microsimulation. Sensitivity analysis was used to assess the impact of varying parameter values on results. Results For the base case of 60-year-old men, all strategies incorporating prostate MRI extended QALYs and life-years compared with watchful waiting and non-MRI strategies. Annual MRI strategies yielded 16.19 QALYs, annual biopsy with no MRI yielded 16.14 QALYs, and watchful waiting yielded 15.94 QALYs. Annual MRI with PI-RADS score of at least 3 or of at least 4 as the biopsy threshold and annual MRI with biopsy even after MRI with negative findings offered similar QALYs and the same unadjusted life expectancy: 23.05 life-years. However, a PI-RADS score of at least 4 yielded 42% fewer lifetime biopsies. With a cost-effectiveness threshold of $100 000 per QALY, annual MRI with biopsy for lesions with PI-RADS scores of 4 or greater was most cost-effective (incremental cost-effectiveness ratio, $67 221 per QALY). Age, treatment type, risk of initial grade misclassification, and quality-of-life impact of procedural complications affected results. Conclusion The use of active surveillance (AS) with biopsy decisions guided by findings from annual MRI reduces the number of biopsies while preserving life expectancy and quality of life. Biopsy in lesions with PI-RADS scores of 4 or greater is likely the most cost-effective AS strategy for men with low-risk prostate cancer who are younger than 70 years. © RSNA, 2021 Online supplemental material is available for this article.

The Association of Veterans' PSA Screening Rates with Changes in USPSTF Recommendations

Becker, Daniel J; Rude, Temitope; Walter, Dawn; Wang, Chan; Loeb, Stacy; Li, Huilin; Ciprut, Shannon; Kelly, Matthew; Zeliadt, Steven B; Fagerlin, Angela; Lepor, Herbert; Sherman, Scott; Ravenell, Joseph E; Makarov, Danil V
BACKGROUND:In 2012, the United States Preventative Services Task Force (USPSTF) formally recommended against all Prostate Specific Antigen (PSA) screening for prostate cancer. Our goal was to characterize PSA screening trends in the Veterans Health Administration (VA) before and after the USPSTF recommendation, and to determine if PSA screening was more likely to be ordered based on a Veteran's race or age. METHODS:Using the VA Corporate Data Warehouse, we created 10 annual groups of PSA-eligible men covering 2009-2018. We identified all PSA tests performed in the VA to determine yearly rates of PSA screening. All statistical tests were two-sided. RESULTS:The overall rate of PSA testing in the VA decreased from 63.3% in 2009 to 51.2% in 2018 (p<.001). PSA screening rates varied markedly by age group during our study period, with men aged 70-80 having the highest initial rate and greatest decline (70.6% in 2009 to 48.4% in 2018, p<.001). Men aged 55-69 saw a smaller decline (65.2% in 2009 to 58.9% in 2018, p<.001) while the youngest men, aged 40-54, had an increase in PSA screening (26.2% in 2009 to 37.8 in 2018, p<.001). CONCLUSIONS:In this analysis of PSA screening rates among veterans before and after the 2012 USPSTF recommendation against screening, we found that overall PSA screening decreased only modestly, continuing for more than half of the men in our study. Veterans of different races had similar screening rates, suggesting that VA care may minimize racial disparities. Veterans of varying age experienced significantly different trends in PSA screening.

Gender Bias in Medicine: Does it Exist at AUA Plenary Sessions?

Davuluri, Meenakshi; Barry, Emily; Loeb, Stacy; Watts, Kara
OBJECTIVE:To determine if gender bias exists at the plenary sessions of the American Urologic Association (AUA) annual conference by evaluating variations in the use of a professional title (PT) during speaker introductions at these sessions. METHODS:We retrospectively reviewed video archives of all plenary sessions from the American Urologic Association annual conferences from 2017-2019. Videos that included both plenary introducer and speaker were included for analysis. The following data were collected: conference year, gender and academic rank of 'introducer' and of 'speaker', and use of PT (ie: doctor) during speaker introduction. Variations in use of PT for introductions of speakers based on gender of introducer and of speaker were analyzed by chi-square tests. RESULTS:414 videos were reviewed; 195 (47%) with a composite 622 introducer/speaker pairs were reviewed and analyzed. Only 8.7% of introducers and 14.6% of speakers were female (Table 1). Overall, there was no difference in the use of PT for introductions of female versus male speakers (61.5% vs 60.8%, p = 0.90). However, male speakers were more likely to be introduced as doctor when introduced by a female versus a male (75.60% vs 59.60%, p=0.04). Female speakers were equally likely to be introduced as doctor regardless of introducer gender. CONCLUSIONS:Men represented the majority of presenters and speakers in the plenary session at American Urological Association meetings. However, there is not a significant difference in the use of professional title for AUA plenary speaker introductions based on gender.

Leveraging Social Media as a Thermometer to Gauge Patient and Caregiver Concerns: COVID-19 and Prostate Cancer

Loeb, Stacy; Mihalcea, Rada; Perez-Rosas, Veronica; Xu, Alex; Taylor, Jacob; Byrne, Nataliya; Walter, Dawn; Ness, Marina; Robbins, Rebecca; Zhang, Sylvia; Killeen, Trevor; Natesan, Divya; Borno, Hala T
The COVID-19 pandemic dramatically impacted society and health care on a global scale. To capture the lived experience of patients with prostate cancer and family members/caregivers during the COVID-19 pandemic, we performed a mixed-methods study of posts to two online networks. We compared all 6187 posts to the Inspire Us TOO Prostate Cancer online support and discussion community from December 2019 to April 2020, to 6926 posts from the same interval in 2019, applying a linguistic ethnography method. A similar analysis was performed using data from the Reddit discussion website (246 posts from 2019 and 260 posts from 2020). Manual qualitative analysis was performed for all 207 posts that mentioned COVID, COVID-19, or coronavirus. The computational linguistic ethnography analysis revealed a more collective tone in 2020, with increased concern about death. Our qualitative analysis showed that patients with prostate cancer and caregivers have concern about a variety of COVID-19-related impacts on care, including delays in testing and treatment. There was also substantial concern about the impact of having cancer on COVID-19 risk and access to COVID-19 care. Misinformation was present in 7% of COVID-19-related posts. In conclusion, online networks provide a useful source of real-world data from patients and their families, and analysis of these data highlighted a substantial impact of COVID-19 on prostate cancer care.

Prostate cancer

Rebello, Richard J; Oing, Christoph; Knudsen, Karen E; Loeb, Stacy; Johnson, David C; Reiter, Robert E; Gillessen, Silke; Van der Kwast, Theodorus; Bristow, Robert G
Prostate cancer is a complex disease that affects millions of men globally, predominantly in high human development index regions. Patients with localized disease at a low to intermediate risk of recurrence generally have a favourable outcome of 99% overall survival for 10 years if the disease is detected and treated at an early stage. Key genetic alterations include fusions of TMPRSS2 with ETS family genes, amplification of the MYC oncogene, deletion and/or mutation of PTEN and TP53 and, in advanced disease, amplification and/or mutation of the androgen receptor (AR). Prostate cancer is usually diagnosed by prostate biopsy prompted by a blood test to measure prostate-specific antigen levels and/or digital rectal examination. Treatment for localized disease includes active surveillance, radical prostatectomy or ablative radiotherapy as curative approaches. Men whose disease relapses after prostatectomy are treated with salvage radiotherapy and/or androgen deprivation therapy (ADT) for local relapse, or with ADT combined with chemotherapy or novel androgen signalling-targeted agents for systemic relapse. Advanced prostate cancer often progresses despite androgen ablation and is then considered castration-resistant and incurable. Current treatment options include AR-targeted agents, chemotherapy, radionuclides and the poly(ADP-ribose) inhibitor olaparib. Current research aims to improve prostate cancer detection, management and outcomes, including understanding the fundamental biology at all stages of the disease.

Clinical Implications of Germline Testing in Newly Diagnosed Prostate Cancer

Loeb, Stacy; Giri, Veda N
CONTEXT/BACKGROUND:Germline testing (GT) is increasingly impacting prostate cancer (PCa) management and screening, with direct effects in urology, medical oncology, and radiation oncology. The majority of testing indications and recommendations center on men with metastatic disease, although guidelines now encompass newly diagnosed, early-stage PCa and entail assessment of personal history, pathologic features, and family history to determine eligibility for testing. OBJECTIVE:To describe current guidelines on GT for men with PCa and the impact on management. An additional objective was to review the literature on current uptake of GT across practice settings. EVIDENCE ACQUISITION/METHODS:A nonsystematic review was performed of current guidelines on GT in PCa from professional societies and consensus conferences, detailing supporting evidence for these recommendations. This was supplemented by a literature review of uptake of GT and precision medicine in practice. EVIDENCE SYNTHESIS/RESULTS:Multiple guidelines and consensus panels recommend GT for men with metastatic PCa. Guidelines endorse BRCA2 testing in metastatic PCa because of strong evidence for PCa risk, aggressiveness, and PARP inhibitor candidacy. Testing of additional DNA repair genes in metastatic disease is also endorsed across guidelines. Immunotherapy with pembrolizumab is an option in some guidelines for men with DNA mismatch repair deficiency. In localized disease, GT is recommended on the basis of histologic features and family history; criteria vary between guidelines. GT for localized disease informs hereditary cancer risk and will probably impact future PCa management. Practice gaps exist regarding utilization of GT. CONCLUSIONS:Germline evaluation is increasingly important in the management of men with metastatic PCa and may also affect the prognosis for men with localized disease. The presence of germline mutations has important hereditary cancer implications for men and their families. Uptake of germline evaluation may be underutilized in some practice settings, so strategies for optimization are required. PATIENT SUMMARY/UNASSIGNED:Patients with prostate cancer should talk to their doctor about the pros and cons of genetic testing, with attention to family history and cancer features. Genetic testing can have important implications for treatment, cancer screening, and family cancer risk.
