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.

Association between pelvic nodal radiotherapy and patient-reported functional outcomes through 5 years among men undergoing external-beam radiotherapy for prostate cancer: an assessment of the Comparative Effectiveness Analysis of Surgery and Radiation (C
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.

Have screening harms become newsworthy? News coverage of prostate and colorectal cancer screening since the 2008 USPSTF recommendation changes.
The researchers aimed to determine whether newspapers portrayed screening for prostate and colorectal cancers differently after the 2008 USPSTF recommendation changes. In US newspapers from 2005 to 2012, they found that benefits in prostate cancer screening articles and harms and benefits in colonoscopy articles did not change over time, but mentions of prostate cancer screening harms increased after 2008. They concluded that consumers, especially lay consumers, are receiving unbalanced information on cancer screening.

A peripheral circulating TH1 cytokine profile is inversely associated with prostate cancer risk in CLUE II.
The authors evaluated the association between peripheral-cytokine concentrations and prostate cancer. They found that men with a prediagnostic circulating TH1 profile and higher IL6 may have a lower risk of prostate cancer, including aggressive disease. They concluded that identifying specific inflammatory cytokines associated with prostate cancer may lead to improved prevention and treatment strategies.

Health-care utilization by prognosis profile in a managed care setting: using the Surveillance, Epidemiology and End Results Cancer Survival Calculator SEER*CSC.
The authors described health service utilization patterns of subgroups of prostate cancer and colorectal cancer (CRC) patients with different relative probabilities of dying of their cancer or other conditions. They found that although a new diagnosis of cancer increased utilization of cancer-related services for an extended time period, the timing of cancer diagnosis did not appear to affect other types of utilization.

The Surveillance, Epidemiology, and End Results Cancer Survival Calculator SEER*CSC: validation in a managed care setting.
The researchers externally validate the nomograms for prostate and colorectal cancer using data from Kaiser Permanente Colorado. Their results indicated that the colorectal and prostate cancer nomograms are reliable tools for physicians and patients to use to obtain information on prognosis and assist in establishing priorities for both treatment of the cancer and other conditions, particularly when a patient is elderly and/or has significant comorbidities.

Toward better use of bone scans among men with early-stage prostate cancer.
This study evaluated the performance of published guidelines compared with that of current practice for radiographic staging of men with newly diagnosed prostate cancer. It found that, based on current practice patterns, more uniform application of existing guidelines would ensure that bone scans are performed for almost all men with bone metastases, while avoiding many negative imaging studies.

Perceptions of prostate cancer fatalism and screening behavior between United States-born and Caribbean-born Black males.
The purpose of this study was to compare perceptions of prostate cancer (CaP) fatalism and predictors of CaP screening with Prostate Specific Antigen (PSA) testing between U.S.-born and Caribbean-born African-American males. In their study of 211 U.S.-born and Caribbean-born Black males between ages 39–75, the researchers found that nativity was not a significant predictor of CaP screening with PSA testing within the last year.

Factors associated with adoption of robotic surgical technology in US hospitals and relationship to radical prostatectomy procedure volume.
The authors aimed to identify the factors associated with hospitals' decisions to adopt robotic technology and the consequences of these decisions. They found that hospitals in areas where a higher proportion of other hospitals had already acquired a robot were more likely to acquire one, as were those with more than 300 beds and teaching hospitals. They also found a significant association between years with a robot and the change in the number of radical prostatectomies. They concluded that local area robot competition was associated with the rapid spread of robot technology in the United States.
