Abstract

Background: Rural areas have higher cardiovascular disease (CVD) incidence and age-adjusted mortality rates in the general population. However, the impact of rurality on CVD development and outcomes in patients with prostate cancer (PC) remains unclear.

Patients and methods: This retrospective cohort study used the SEER-Medicare database to analyze males aged ≥65 years diagnosed with PC between 2009 and 2017. The primary exposures were patient rurality status (metropolitan, urban, or rural) and patient-provider rurality, which combined the provider's status (metropolitan vs nonmetropolitan) with the patient's rurality. The primary outcomes included post-PC CVD (comprising heart failure, atrial fibrillation, acute myocardial infarction, peripheral artery disease, and ischemic stroke), cardiovascular mortality (CVDm), prostate cancer-specific mortality (PCSm), and all-cause mortality. Multivariable Fine-Gray and extended Cox models were used to assess the impact of rurality impact on these outcomes.

Results: A total of 103,327 older men were included in the study, of whom 3,631 were from rural areas and 1,857 were rural patients with nonmetropolitan providers. Compared with metropolitan patients, those from rural areas had a 28% higher risk of PCSm (subdistribution hazard ratio [SHR], 1.28; 95% CI, 1.14-1.44) and a 15% higher risk of all-cause mortality (adjusted hazard ratio [aHR], 1.15; 95% CI, 1.07-1.23). Compared with urban patients, rural patients had a 7% higher risk of CVD (SHR, 1.07; 95% CI, 1.01-1.13). No significant differences were observed in CVDm. Among patients receiving androgen deprivation therapy (n=16,811), rurality was associated with a 27% higher risk of PCSm (SHR, 1.27; 95% CI, 1.07-1.51) and a 29% higher risk of all-cause mortality (aHR, 1.29; 95% CI, 1.12-1.49). Rural patients who received care from nonmetropolitan providers had higher risks of PCSm and all-cause mortality compared with those treated by metropolitan providers.

Conclusions: Rurality is associated with higher risks of CVD, PCSm, and all-cause mortality compared with metropolitan and urban patients. Provider rurality further increases these risks, underscoring the critical role of health care access and quality in rural health disparities.

期刊介绍: JNCCN—Journal of the National Comprehensive Cancer Network is a peer-reviewed medical journal read by over 25,000 oncologists and cancer care professionals nationwide. This indexed publication delivers the latest insights into best clinical practices, oncology health services research, and translational medicine. Notably, JNCCN provides updates on the NCCN Clinical Practice Guidelines in Oncology® (NCCN Guidelines®), review articles elaborating on guideline recommendations, health services research, and case reports that spotlight molecular insights in patient care. Guided by its vision, JNCCN seeks to advance the mission of NCCN by serving as the primary resource for information on NCCN Guidelines®, innovation in translational medicine, and scientific studies related to oncology health services research. This encompasses quality care and value, bioethics, comparative and cost effectiveness, public policy, and interventional research on supportive care and survivorship. JNCCN boasts indexing by prominent databases such as MEDLINE/PubMed, Chemical Abstracts, Embase, EmCare, and Scopus, reinforcing its standing as a reputable source for comprehensive information in the field of oncology.
