Functional outcomes after localized prostate cancer treatment.
The objective of this observational cohort study was to compare rates of adverse functional outcomes between specific treatments for localized prostate cancer. Researchers used data from five U.S. Surveillance, Epidemiology, and End Results Program registries. Participants were patients treated for localized prostate cancer in 2011-2012. The results indicated that radical prostatectomy was associated with worse urinary incontinence, but not with worse sexual function, at 10-year followup when compared with radiotherapy or surveillance. Among patients with unfavorable-prognosis disease, external beam radiotherapy with androgen deprivation therapy was associated with worse bowel and hormone function at 10-year followup compared with radical prostatectomy.

Prostate volume, baseline urinary function, and their association with treatment choice and post-treatment urinary function in men treated for localized prostate cancer.
The purpose of this study was to assess the relationship between prostate volume (PV) and baseline urinary function with treatment choice and post-treatment urinary function among men with localized prostate cancer. The researchers identified 1,647 patients from CEASAR, a multicenter population-based, prospective cohort study of men with localized prostate cancer. The primary study outcomes were treatment choice and health-related quality of life (HRQOL) assessed at pre-specified intervals up to 5 years. The study found that median baseline PV was 36 mL (IQR 27-48), and baseline urinary irritative/obstructive domain score was 87 (IQR 75-100). The study did not find any observed clinically meaningful relationship between PV and treatment choice or post-treatment urinary function. In participants with poor baseline urinary function, treatment with radiation or surgery was related with statistically and clinically significant improvement in urinary function at 6 months which endured through 5 years.

Association between hospital competition and quality of prostate cancer care.
The purpose of this retrospective study was to explore the relationship between hospital competition and outcomes in elderly with localized prostate cancer (PCa). The researchers also evaluated whether race moderated the relationship. The researchers applied the Hirschman-Herfindahl index (HHI) to measure hospital competition. The study outcomes were emergency room (ER) visits, hospitalizations, Medicare expenditure and mortality assessed in acute survivorship phase (two years post-PCa diagnosis), and long-term mortality. The study found that among 253,176 patients, percent change in incident rate of ER visit was 17% higher for one unit increase in HHI. Incident rate of ER was 24% higher for whites and 48% higher for African Americans. For one unit increase in HHI, hazard of short-term all-cause mortality was 7% higher for whites and 11% lower for African Americans. The hazard of long-term all-cause mortality was 10% higher for whites and 13% higher for African Americans.

Telehealth use and perceptions among prostate cancer survivors.
Researchers surveyed a sociodemographically diverse population-based cohort of prostate cancer survivors about their usage and perceptions of telehealth during the COVID-19 pandemic. While less than a third of survivors used telehealth at the time of survey and only 10% thought telehealth care was comparable an in-person visit, more than half felt telehealth was a good option for initial consultations or basic care. Survivors with lower education had marginally lower use of telehealth. The researchers concluded that differences in survivor perceptions of telehealth by education level highlighted underlying disparities in telehealth use and offered potential targets for interventions.

In-office dispensing of oral targeted agents by urology practices in men with advanced prostate cancer.
Researchers investigated the dispensing oral targeted agents for advanced prostate cancer treatment directly to patients in urologists’ offices, and whether this delivery model improves access to these agents especially for Black men who are historically undertreated. Their retrospective cohort study used national Medicare data for men with advanced prostate cancer managed by urology practices with and without in-office dispensing. They concluded that this model of delivery could improve access to this class of medications.

Continuity of care and advanced prostate cancer.
This study’s objective was to assess the association of provider continuity of care with outcomes among Medicare fee-for-service beneficiaries with advanced prostate cancer and its variation by race. This retrospective study used SEER-Medicare data of African American and white Medicare beneficiaries aged 66 or older and diagnosed with advanced prostate cancer between 2000 and 2011. The authors used at least 5 years of follow-up data. Short-term outcomes examined were emergency room (ER) visits, hospitalizations, and cost during acute survivorship phase (2-year post-diagnosis), and mortality (all-cause and prostate cancer-specific) during the follow-up period. They calculated continuity of care using Continuity of Care Index (COCI) and Usual Provider Care Index (UPCI), for all visits, oncology visits, and primary care visits in acute survivorship phase. They performed similar analysis for continuity of care in the 2-year period following acute survivorship phase. They found that a one unit increase in COCI was associated with reduction in short-term ER visits (incidence rate ratio [IRR] = 0.65), hospitalizations (IRR = 0.65), and cost (0.64) and lower hazard of long-term mortality. The benefits of higher continuity of care were greater for African Americans than white patients.

Understanding the role of urology practice organization and racial composition in prostate cancer treatment disparities.
This study examined the associations between urology practice organization and racial composition and treatment patterns for Medicare beneficiaries with incident prostate cancer. The authors used a 20% sample of national Medicare data to identify beneficiaries diagnosed with prostate cancer between January 2010 and December 2015 and followed them through 2016. They then linked urologists to their practices with tax identification numbers and patients to their practices based on their primary urologist. They identified 54,443 patients with incident prostate cancer, with most (87%) White and 9% Black. They found wide variation in racial practice composition and practice segregation. Patients in practices with the highest proportion of Black patients had the lowest socioeconomic status (43.1%), highest comorbidity (9.9% with comorbidity score ≥ 3), and earlier age at prostate cancer diagnosis (33.5% age 66-69 years). Black patients had lower odds of definitive therapy and underwent less treatment than White patients in every practice context. Black patients had lower predicted probability of treatment (66%) than White patients (69%).

Understanding the sexual health perceptions, concerns, and needs of female partners of prostate cancer survivors.
The adverse effects of prostate cancer (PCa) and its treatment can critically undermine the sexual well-being of patients and couples. However, limited research has been dedicated to understanding the influence of PCa-induced sexual dysfunction on the female partners of survivors. The purpose of this study was to carry out a qualitative investigation to comprehensively capture the perceptions of female partners regarding the repercussions of PCa on their sex lives, and their partners’ sexual health concerns and unfulfilled needs. The researchers conducted semi-structured telephonic interviews concerning sexual health and unfulfilled needs with female partners of PCa survivors. Participants were recruited from multiple clinical sites and PCa caregivers' support groups from September 2021 to March 2022. Interviews were recorded, transcribed, and independently coded. The study outcomes were on the sexual health concerns and unfulfilled needs of the female partners. Of the 12 participants, the median age was 65 (between 53 and 81), nine identified as White, the median duration since their partner's PCa diagnosis was 2.25 years (ranging from 11 months to 20 years), and most reported their partner had undergone radical prostatectomy, radiation, and/or hormonal therapy. Major themes emerging from the study concerned the substantial effect of age- and PCa-related sexual dysfunction on the sexual quality of life for women, the joint nature of sexual dysfunction and recovery, the partner's role in managing and adapting to sexual dysfunction, communication barriers regarding sexual dysfunction within an intimate relationship, the absence of sexual health counseling and support from physicians, and the advantage of peer interactions and proactive information seeking in addressing unfulfilled sexual health needs. The study concluded that female partners perceive PCa-related sexual dysfunction as a shared issue for couples, express sorrow due to age- and PCa-related sexual losses, and experience a void in physician-led sexual health counseling and information.

Cardiovascular disease prevention and management of pre-existent cardiovascular disease in a cohort of prostate cancer survivors.
This study examined receipt of preventive care and management of pre-existing cardiovascular disease (CVD) in a prospective cohort of men newly diagnosed with prostate cancer between 2011 and 2013 throughout North Carolina linked to Medicare and private insurance claims and clinical data from the Veterans Affairs (VA). Primary outcome for patients with pre-existent CVD was a composite measure of annual preventive care (blood glucose screening, cholesterol level testing, and ≥ 1 primary care provider visit). The sample comprised 492 patients successfully linked to insurance claims and/or VA data, among whom 103 (20.9%) had pre-existent CVD. Receipt of preventive care declined from 52.7% during the first year after prostate cancer diagnosis to 40.8% during the third year. Among patients with pre-existent CVD, only 23.4% saw a cardiologist in all 3 years. Black men were more likely than White men to visit a cardiologist during the first year after diagnosis.

Association between adherence to radiation therapy quality metrics and patient reported outcomes in prostate cancer.
Researchers evaluated the impact of compliance with nationally recognized radiation therapy quality measures on patient-reported health-related quality of life outcomes in the Comparative Effectiveness Analysis of Surgery and Radiation (CEASAR) population-based, prospective cohort study of men with localized prostate cancer. Eight quality measures were identified based on national guidelines. In multivariable analyses, no clinically significant associations were discovered between compliance with evaluated radiation therapy quality measures and patient-reported outcomes such as urinary irritation, urinary incontinence, bowel, sexual or hormonal function. The researchers concluded that further work would be needed to identify patient-centered quality measures of prostate cancer care.

Sleep disturbances are underappreciated in prostate cancer survivorship.
Limited research exists on the prevalence of sleep issues in prostate cancer (PCa) survivors and the degree of urologist involvement in addressing sleep-related concerns. The researchers conducted a survey with PCa survivors (n = 167) and urologists (n = 145) to examine sleep problems and survivorship care practices. The study found a significant number of PCa survivors experienced sleep difficulties, with 50.9% reporting suboptimal sleep quality, 18.0% suffering from moderate/severe insomnia, and 36.5% at an elevated risk for sleep apnea. However, only a small number of urologists consistently screened for sleep disruptions, as advised in national cancer survivorship guidelines.

Patient-reported outcomes after external beam radiotherapy with low dose rate brachytherapy boost vs radical prostatectomy for localized prostate cancer: five-year results from a prospective comparative effectiveness study.
The purpose of this study was to compare patient reported outcomes through 5 years following radical prostatectomy or external beam radiation therapy with low dose rate brachytherapy boost for localized prostate cancer. The researchers enrolled men 80 years of age or under who had localized prostate adenocarcinoma and followed them longitudinally from 2011 to 2012. The study found that when compared with radical prostatectomy, external beam radiation therapy with low dose rate brachytherapy boost was related with clinically meaningful worse urinary irritative/obstructive and better urinary incontinence function through 5 years. Urinary function bother was similar between groups. Treatment with external beam radiation therapy with low dose rate brachytherapy boost was associated with worse bowel function through 5 years compared to radical prostatectomy. Treatment with external beam radiation therapy with low dose rate brachytherapy boost was associated with better sexual function at 1 year compared to radical prostatectomy, but there was insufficient evidence to reject the supposition that no difference was seen at 3 or 5 years. The researcher concluded that external beam radiation therapy with low dose rate brachytherapy boost was related with clinically meaningful worse urinary irritative/obstructive and bowel functions but better urinary incontinence function through 5 years after treatment compared to radical prostatectomy.

Unmet sexual health needs of patients and female partners following diagnosis and treatment for prostate cancer.
This study’s objective was to perform a qualitative study to identify unmet sexual needs of patients and female partners after prostate cancer diagnosis. The authors conducted a qualitative study of posts to the Inspire Us TOO Prostate Cancer Online Support and Discussion Community. They identified 6,192 posts in the Sexual Health & Intimacy forum of the community, of which 661 posts were from female authors. A random sample of 10% of posts from female partners and an equal number of randomly selected posts from male patients were analyzed. Multiple themes emerged that were unique to female partners of prostate cancer survivors including included expanding the sexual repertoire, feeling invisible, contextualizing sexual intimacy within the broader picture of survival, and addressing relationship concerns. Patients and their partners had common concerns, including not receiving sufficient information from healthcare providers regarding sexual side effects from prostate cancer and its treatment. A limitation may be that members of the online community may not be representative of all couples facing prostate cancer. This study also does not examine sexual health needs among gay and bisexual couples.

Systematic review of the impact of a plant-based diet on prostate cancer incidence and outcomes.
The objective of this study was to perform a systematic review of plant-based diets and prostate cancer. Findings showed that interventional studies displayed generally favorable results of lifestyle modifications incorporating a plant-based diet with prostate cancer outcomes as well as improvements in nutrition and general health. Further, observational studies demonstrated either a lower risk of prostate cancer or no significant difference.

The influence of practice structure on urologists' treatment of men with low-risk prostate cancer.
Researchers examined the influence of type of practice structure, and by implication the financial incentives associated with each structure, on treatment received among men newly diagnosed with low-risk prostate cancer. They found that physician practice structure attributes were significantly associated with type of treatment received but few studies controlled for such factors. Their findings - coupled with the observation that urologist practice structure shifted substantially over this time period due to mergers of small urology groups - provided one explanation for the limited uptake of active surveillance among men with low-risk disease in the US.

Risk of metabolic and cardiovascular adverse events with abiraterone or enzalutamide among men with advanced prostate cancer.
Investigators examined the association between the use of abiraterone or enzalutamide and the risk of metabolic or cardiovascular adverse events while on treatment for advanced prostate cancer. They found that, compared with men not receiving abiraterone, men receiving abiraterone were at increased risk of both a major composite adverse event and a minor composite adverse event. Compared with men not receiving enzalutamide, men receiving enzalutamide were at an increased risk of a major composite adverse event but not a minor composite adverse event. They recommended careful monitoring and management of men on abiraterone or enzalutamide through team-based approaches.

Association between treatment for localized prostate cancer and mental health outcomes.
Researchers conducted a prospective population-based analysis using the Comparative Effectiveness Analysis of Surgery and Radiation (CEASAR) study to compare mental health outcomes for men undergoing treatment for localized prostate cancer. Results showed that there were no clinically important differences in mental health outcomes; however, the researchers identified a number of characteristics associated with worse mental health outcomes. These included: older age, poorer health, and being unmarried.

In this study, the investigators sought to compare functional outcomes for men receiving prostate and pelvic versus prostate-only radiotherapy, longitudinally over 5 years. The investigators concluded that there were no clinically important differences in disease-specific or general health-related quality of life with the addition of pelvic irradiation to prostate radiotherapy, supporting the use of pelvic radiotherapy when it may be of clinical benefit, such as men with increased risk of nodal involvement.

Documenting horizontal integration among urologists who treat prostate cancer.
The purpose of this study was to create and employ a methodology to document changes in physician practice structure resulting from horizontal mergers among urology groups. To identify all urologists who treated men with prostate cancer, the researchers integrated cancer registry records from four large states with Medicare Part B claims. Information from SK & A surveys and extensive internet searches was added to assign a practice structure to each urologist-year from 2005-2014. The study found that horizontal merging among small urology groups resulted in a strong increase in the percentage of urologists who belong to large urology practices with ownership in anatomical pathology services and/or intensity modulated radiation therapy. By 2014, small percentages (7%-16%) of New Jersey, Florida and Texas urologists were employed by a health system, whereas more than half of New Jersey urologists and about 43% of urologists in Florida and Texas were members of large practices. This is compared to California urologists of which only 17.5% had ownership in intensity modulated radiation therapy and/or pathology services. The researchers highlighted that the study indicators of market share of urologists connected with each practice structure type were highly correlated with indicators of market share based on quantity of prostate cancer events treated by each type of practice structure.

Sexual function outcomes of radiation and androgen deprivation therapy for localized prostate cancer in men with good baseline function.
This retrospective review study sought to compare sexual function through 5 years for men undergoing radiation treatment for localized prostate cancer with and without systemic androgen deprivation therapy. Out of a cohort of 167 patients, 73 underwent radiation alone and 94 received androgen therapy deprivation therapy plus radiation. Androgen deprivation therapy was associated with worse sexual function through the first year regardless of disease risk. By 3 years the difference was no longer significant for the 51 patients with intermediate-risk disease. Worse sexual function for high-risk disease patients who received androgen deprivation therapy was shown at 3 years but not at 5 years.

Association of treatment modality, functional outcomes, and baseline characteristics with treatment-related regret among men with localized prostate cancer.
Treatment-related regret is an integrative, patient-centered measure that accounts for morbidity, oncologic outcomes, and anxiety associated with prostate cancer diagnosis and treatment. The objective of this study was to assess the association between treatment approach, functional outcomes, and patient expectations and treatment-related regret among patients with localized prostate cancer. The investigators concluded that the findings of their cohort study suggested that more than 1 in 10 patients with localized prostate cancer experienced treatment-related regret.

Continuity of care in acute survivorship phase, and short and long-term outcomes in prostate cancer patients.
This study examined the association between continuity of care and outcomes in Medicare beneficiaries with localized prostate cancer, and the moderating effect of race using SEER – Medicare data between 2000 and 2016. Continuity of care was defined as visits dispersion and density in the acute survivorship phase. Outcomes measured were emergency room visits, hospitalizations, and cost during the acute survivorship phase and mortality over the follow-up phase. Higher continuity of care was associated with improved outcomes. The interaction between race and continuity of care was significant.

Mapping the Memorial Anxiety Scale for Prostate Cancer to the SF-6D.
The purpose of this study was to create a crosswalk that predicts Short Form 6D (SF-6D) utilities from Memorial Anxiety Scale for Prostate Cancer (MAX-PC) scores. Findings showed that this study provided a crosswalk that converts MAX-PC scores to SF-6D utilities for economic evaluation of clinically significant prostate cancer-related anxiety treatment options for prostate cancer survivors.

Prospects for daily online adaptive radiotherapy via ethos for prostate cancer patients without nodal involvement using unedited CBCT auto-segmentation.
This study’s objective was to assess the new online adaptive radiation therapy technology called Ethos for treating prostate cancer. Twenty-five prostate patients previously treated at the author’s clinic were re-planed using an Ethos emulator. Clinical margins of 3 mm posterior, 5 mm left/right/anterior, and 7 mm superior/inferior were used. Dose metrics were compared to unadapted plans to evaluate clinical target volumes (CTV) and online adaptive radiation (OAR) dose changes. Overall, 96% of fractions required auto-segmentation edits, although they were mostly minor. Adaptation improved CTV 98% for the 24 patients with minor auto-segmentation corrections. However, for one in 25 patients, large contour edits were required.
