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.
