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.

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.

Urology workforce changes and implications for prostate cancer care among Medicare enrollees.
The purpose of this study was to characterize national trends in urologist workforce, practice organization, and management of incident prostate cancer. The investigators characterized shifts in urologist membership from smaller, independent groups to larger, multispecialty or hospital-owned practices. They indicated that this trend coincided with higher utilization of observation and surgical treatment for prostate cancer.

Factors influencing treatment of veterans with advanced prostate cancer.
This study examined factors influencing treatment of veterans with metastatic castration-resistant prostate cancer (CRPC). Clinician and nonclinical factors associated with the first-line treatment for CPRC using data from the Veterans Health Administration was used. Almost 5000 patients who received abiraterone, enzalutamide, docetaxel, or ketoconazole from 2010 through 2017 were identified. Increasing age was associated with receipt of abiraterone or enzalutamide versus docetaxel. Greater preexisting comorbidity was associated with enzalutamide versus abiraterone. Patients with higher PSA values at the start of treatment were more likely to receive docetaxel than the other three treatments. African American men were more likely to receive ketoconazole.

Five-year outcomes from a prospective comparative effectiveness study evaluating external-beam radiotherapy with or without low-dose-rate brachytherapy boost for localized prostate cancer.
This retrospective cohort study’s objective was to determine if there were differences in treatment-related regret or survival between prostate cancer patients who received external-beam radiation therapy (EBRT) with or without a brachytherapy boost (EBRT-LDR), over a 5-year period. The cohort included 695 men who met inclusion criteria and received either EBRT (n=583) or EBRT-LDR (n=112). Men who received either treatment reported clinically worse urinary irritation and bowel function through 3 years but resolved after 5 years. Men who received EBRT-LDR continued to report moderate- to-big problems with urinary function bother and frequent urination at 5 years. There was no difference in treatment-related regret or survival between patients who received either treatment.

Reactions to recommendations and evidence about prostate cancer screening among White and Black male veterans.
This study looked at differences in attitudes about recommendations and evidence on prostate cancer screening among White and Black male veterans. The authors provided a draft educational pamphlet about the benefits and harms of Prostate Specific Antigen (PSA) screening to 44 men, ages 55-81 at a midwestern VA medical center in 2013 and 2015. The groups were divided into four White and two Black focus groups. Three universal themes were low baseline familiarity with prostate cancer, surprise and resistance to the guidelines not to test routinely, and negative emotions in response to ambiguity. Discussions in the White groups highlighted the potential benefits of screening, minimized the harms, and emphasized personal choice in screening decisions. Discussions in Black groups devoted almost no time to benefits, considered harms significant, and emphasized personal and collective responsibility for cancer prevention through diet, exercise, and alternative medicine. Discussion in Black groups also emphasized the history of racism and discrimination in healthcare and medical research.

Therapies for clinically localized prostate cancer: a comparative effectiveness review.
In this study, the investigators sought to identify new information evaluating clinically localized prostate cancer therapies. The investigators concluded that radical prostatectomy reduced mortality vs watchful waiting in clinically detected localized prostate cancer but caused more harms. Effectiveness may be limited to younger men and those with intermediate risk disease. Active monitoring resulted in little to no mortality difference vs radical prostatectomy or external beam radiation plus androgen deprivation.

Patient-reported financial toxicity associated with contemporary treatment for localized prostate cancer.
Contemporary treatment modalities for localized prostate cancer provide comparable overall and cancer-specific survival. However, the degree of financial burden imposed by treatment, the factors contributing to that burden, and how different treatments compare with regard to financial toxicity remain poorly understood. The investigators sought to explore these factors. They concluded that external beam radiotherapy was associated with the highest financial burden, even when controlling for age, education and income.

Cost-effectiveness of a biopsy-based 8-protein prostate cancer prognostic assay to optimize treatment decision making in Gleason 3 + 3 and 3 + 4 early stage prostate cancer.
A novel 8-protein prognostic assay generates a risk score at time of biopsy that is predictive of prostate cancer aggressiveness and can inform treatment decisions. The objective of this study was to evaluate the cost-effectiveness of using the assay to inform treatment decisions compared with usual care. The 8-protein assay strategy resulted in 0.04 more quality-adjusted life years and $700 less in costs compared with usual care.

The evolution of self-reported urinary and sexual dysfunction over the last two decades: implications for comparative effectiveness research.
This study evaluated differences in pretreatment urinary and sexual function in two population-based cohorts of men with prostate cancer enrolled nearly 20 yrs. apart. It concluded that reporting of pretreatment urinary incontinence and erectile dysfunction has increased over the past two decades. These findings may reflect sociological changes including heightened media attention and direct-to-consumer marketing, among other potential explanations.

Clinicians' perceptions of the benefits and harms of prostate and colorectal cancer screening.
The researchers sought to understand clinicians’ perceptions of the benefits and harms of two screening tests (colonoscopy and prostate-specific antigen (PSA) testing) that differ in their balance of potential benefits and harms. Clinicians perceived PSA testing to have a greater likelihood of harm as well as a lower likelihood of lengthening life relative to colonoscopy.

Quality of life and satisfaction among prostate cancer patients followed in a dedicated survivorship clinic.
The researchers integrated quality of lifer (QOL) assessments into a prostate cancer survivorship clinic and compared recovery and satisfaction among men managed in the survivorship clinic with those followed with more routine care. They concluded that patient QOL and satisfaction were higher among men managed in a survivorship program.

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.

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.
