Association between androgen deprivation therapy use and diagnosis of dementia in men with prostate cancer.
The purpose of this study was to analyze the association between androgen deprivation therapy (ADT) exposure and diagnosis of Alzheimer disease or dementia among elderly men with prostate cancer. Results showed that, among elderly patients with prostate cancer, ADT exposure was associated with subsequent diagnosis of Alzheimer disease or dementia over a follow-up period of at least 10 years.

Castration remains despite decreasing definitive treatment of localized prostate cancer in the elderly: a case for de-implementation.
In this editorial, the authors discuss a study by Yang, et al., published in 2017 in Cancer, in which they used the National Cancer Data Base to examine definitive therapy (prostatectomy or radiotherapy) among 400,000 patients who were diagnosed with intermediate-risk or high-risk prostate cancer between 2004 and 2012.

Racial and ethnic disparities in substance use disorders and outcomes in elderly prostate cancer patients.
This study used Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data to identify prevalence of substance use among patients with advanced-stage prostate cancer. There are racial and ethnic disparities between substance use and outcomes. A multidisciplinary coordinated care approach is recommended to address these disparities.

Falls and frailty in prostate cancer survivors: current, past, and never users of androgen deprivation therapy.
This study compared the prevalence of and association between falls and frailty of prostate cancer survivors (PCSs) who were current, past or never users of androgen deprivation therapy (ADT). It concluded that current and past exposure to ADT is linked to higher risk of falls and frailty than no treatment.

Utilization and predictors of expectant management among elderly men with low-and intermediate-risk localized prostate cancer in U.S. urological practice.
Researchers assessed the use and predictors of expectant management (EM) to understand its uptake in U.S. practice. In U.S. practice, the utilization of EM steadily increased in low-risk prostate cancer and remained low in the intermediate-risk group over time. While patients with advanced age or comorbidities were more likely to receive EM, its use varied substantially by geographic region.

Association between metformin use and cancer stage at diagnosis among elderly Medicare beneficiaries with preexisting Type 2 diabetes mellitus and incident prostate cancer.
The researchers examined the association between metformin use and cancer stage at diagnosis among elderly men with preexisting diabetes mellitus and incident prostate cancer. They found a significantly lower percentage of metformin users were diagnosed with advanced prostate cancer as compared to nonusers (4.7 percent versus 6.7 percent.

Association between types of chronic conditions and cancer stage at diagnosis among elderly Medicare beneficiaries with prostate cancer.
The current retrospective observational study was conducted to examine the association between types of chronic conditions and cancer stage at diagnosis among elderly Medicare beneficiaries with prostate cancer. It found that those with none of the 3 types of chronic conditions (cardiometabolic, mental health, and respiratory) were 44 percent more likely to be diagnosed with advanced prostate cancer compared to men with all 3 types of chronic conditions.

Association between age, substance use, and outcomes in Medicare enrollees with prostate cancer.
The authors analyzed the association between age, substance use, and outcomes in fee-for-service Medicare enrollees with advanced prostate cancer. As they found age-specific results, they recommend an integrated and multidisciplinary approach to screen, refer, and treat substance use in patients with prostate cancer to improve outcomes and reduce costs.

Types of chronic conditions combinations and initial cancer treatment among elderly Medicare beneficiaries with localised prostate cancer.
The authors sought to examine the association between types of chronic conditions combinations and initial cancer treatment among elderly Medicare beneficiaries with localised prostate cancer. They found that a significant proportion of elderly men with chronic conditions have received aggressive initial cancer treatment, and they suggested a conservative approach for the initial prostate cancer treatment among elderly men with significant chronic conditions and localised prostate cancer.

Impact of prostate cancer diagnosis on noncancer hospitalizations among elderly Medicare Beneficiaries with incident prostate cancer.
The authors analyzed the impact of cancer diagnosis on noncancer hospitalizations (NCHs) by comparing these hospitalizations between the precancer and postcancer periods. They found that the rate of NCHs was higher during the postcancer period compared with the precancer period. They suggested that their study highlights the need to design interventions for reducing the excess NCHs after prostate cancer diagnosis among elderly men.

Downstream tests, treatments, and annual direct payments in older men cared for by primary care providers with high or low prostate-specific antigen screening rates using 100 percent Texas U.S. Medicare public insurance claims data: a retrospective cohort
The investigators assessed the tests, treatments, and payments for prostate cancer care in men aged 75 or older who have primary care physicians (PCPs) with high or low prostate specific antigen (PSA) testing rates. They found that older men seeing PCPs with high rates of PSA testing undergo more testing and treatments for prostate cancer, with higher Medicare insurance payments.

Infective endocarditis and cancer in the elderly.
The researchers investigated the magnitude of the association between infective endocarditis and cancer, and the natural history of cancer patients with concomitant diagnosis of infective endocarditis. They found that in this elderly population, the incidence of infective endocarditis around a colorectal cancer diagnosis was substantially higher than around the diagnosis of lung, breast and prostate cancers.

Prostate cancer screening practices and diagnoses in patients age 50 and older, Southeastern Michigan, pre/post 2012.
This study investigated the regional impact of the 2012 U.S. Preventive Services Task Force (USPSTF) recommendation against the use of prostate specific antigen (PSA) screening for prostate cancer. PSA utilization significantly increased during the pre-period, but significantly decreased in the post-period. Prostate biopsies decreased before the 2012 recommendation and did not change afterwards.

Use of forecasted assessment of quality of life to validate time-trade-off utilities and a prostate cancer screening decision-analytic model.
The researchers sought to determine whether the forecasted assessment of how someone would feel in a future health state can be predictive of utilities (e.g. as elicited by the time-trade-off method) and also predictive of optimal decisions as determined by a decision-analytic model. They concluded that anticipated difficulty adjusting to adverse health effects were highly related to preferences and could be used as a proxy measure of utility.

Understanding the racial and ethnic differences in cost and mortality among advanced stage prostate cancer patients (STROBE).
The aims of the study were to understand the racial/ethnic differences in cost of care and mortality in Medicare elderly with advanced stage prostate cancer. It found that relationship between race/ethnicity, cost of care, and mortality is intricate. For non-Hispanic black men, disparity in mortality can be attributed to treatment differences.
