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.

Receipt of cancer screening is a predictor of life expectancy.
The researchers sought to determine the association between receipt of screening mammography or PSA and overall survival. They found that the subjects with prior cancer screening had actual median survivals higher than those who were not screened, with differences ranging from 1.7 to 2.1 years for women and 0.9 to 1.1 years for men.

Impact of adherence to quality measures for localized prostate cancer on patient-reported health-related quality of life outcomes, patient satisfaction, and treatment-related complications.
Given the small number of narrowly focused measures in prostate cancer care, the researchers sought to determine whether adherence to any of the available payer-driven quality measures influences patient-centered outcomes, including health-related quality of life (HRQOL), patient satisfaction, and treatment-related complications. They concluded that compliance with available nationally endorsed quality indicators was not associated with clinically important changes in patient-centered outcomes (HRQOL, satisfaction, or complications) within 1-year.

Economic analysis of prostate-specific antigen screening and selective treatment strategies.
The researchers evaluated the potential cost-effectiveness of plausible prostate-specific antigen (PSA) screening strategies and assessed the value added by increased use of conservative management among low-risk, screen-detected cases. They found that, with contemporary treatment, only strategies with biopsy referral for PSA levels higher than 10.0 ng/mL or age-dependent thresholds were associated with increased quality-adjusted life-years (QALYs), and only quadrennial screening of patients aged 55 to 69 years was potentially cost-effective in terms of cost per QALY. They concluded that, for PSA screening to be cost-effective, it needs to be used conservatively and ideally in combination with a conservative management approach for low-risk disease.

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.

Cardiovascular effects of androgen deprivation therapy for the treatment of prostate cancer: ABCDE steps to reduce cardiovascular disease in patients with prostate cancer.
Since cardiovascular disease risk may be increased by the use of androgen deprivation therapy (ADT), the researchers have adapted the five-step "ABCDE" algorithm for prostate cancer survivors. Its treatment recommendations come under the following headings: awareness and aspirin, blood pressure, cholesterol and cigarettes, diet and diabetes, and exercise. The algorithm is illustrated by a hypothetical case study.

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.

Resource use in the last year of life among patients who died with versus of prostate cancer.
The researchers conducted a retrospective analysis of Surveillance, Epidemiology, and End Results-Medicare data of men with prostate cancer. Patients who died of prostate cancer rather than from other causes had more hospice and outpatient use, less inpatient and ICU use, and lower overall costs. Efforts to shift care toward outpatient settings might provide more efficient and judicious care for patients during the end of life.

The comparative harms of open and robotic prostatectomy in population based samples.
Using population cohort data,the researchers examined sexual and urinary function in men undergoing open radical prostatectomy vs those undergoing robotic assisted radical prostatectomy. They found that men undergoing robotic assisted radical prostatectomy likely experience less decline in early urinary continence and sexual function than those undergoing open radical prostatectomy.

Therapeutic substitutions in the midst of new technology diffusion: the case of treatment for localized prostate cancer.
The authors studied the impact of the fast diffusion of robotic surgical systems on the overall treatment pattern of localized prostate cancer. They found that the density of robotic systems at state-level had a significantly positive impact on the rate of surgery and a significantly negative impact on the rate of radiation therapy. They concluded that part of the increase in the rate of surgery was driven by substitution across treatment types with a large proportion originating from the younger population.

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.
