Prostate cancer is the second most common cancer in U.S. men, with higher incidence and mortality among African Americans and those with genetic or familial risk. Despite guidelines promoting early detection, prostate-specific antigen (PSA) screening in primary care remains inconsistent. We assessed PSA screening patterns and the association between risk factors and testing. A retrospective analysis was conducted on men aged ≥40 seen at primary care clinics from 2020 to 2022. Risk scores were created based on the number of prostate cancer risk factors. Univariate and multivariate analyses assessed associations between the risk scores, PSA screening, and cancer diagnosis. Of 176,326 patients, 31.4% underwent PSA testing, rising to 78.1% with a risk score of 4. The predictive model was significant (χ 2 = 19,527.021, df = 11, p < .001). PSA testing odds were higher with Medicaid or commercial insurance (vs. Medicare) and lower for self-pay patients. Former and never smokers were more likely to be tested than current smokers. Age, African American race, and family history increased the odds of receiving PSA testing. Prostate cancer diagnosis reached 25% at a risk score of 5, with significant predictors including older age, African American race, family history, and mention of “prostate” in clinical notes. PSA screening remains underused in primary care, even among high-risk patients. More risk factors were linked to higher testing rates, but African American and low-income groups were under-tested. Provider education and decision-support tools may improve guideline adherence and equity.

Abstract Purpose In 2019, the National Comprehensive Cancer Network (NCCN) recommended genetic testing for all patients with pancreatic ductal adenocarcinoma (PDAC). To evaluate the status of implementation of these guidelines in a loco-regional setting, we performed a retrospective, observational study among patients with newly diagnosed PDAC who received oncologic care at Northeast Georgia Medical Center in Georgia. Methods Chart abstraction of patients with newly diagnosed PDAC from January 1, 2020 to December 31, 2021, was performed to include information on genetic testing recommendation and completion, and time from diagnosis to testing. The deidentified dataset was then analyzed using appropriate descriptive and associative statistical testing. Results Of the cohort of 109 patients, 32 (29.4%) completed genetic screening; 16 (14.7%) were screened within 10 days of diagnosis. Among the 77 (70.6%) patients who did not receive genetic screening, 45 (41.3%) were not recommended genetic screening despite treatment intent with standard of care therapy. However, 32 (29.4%) were not recommended genetic screening in conjunction with a desire to pursue palliative care/hospice/or due to terminal illness. Conclusions The study highlighted the gap in implementation of NCCN guideline-directed genetic testing in PDAC patients as only a third underwent testing suggesting the need for systematic processes to facilitate testing. The test was more likely to be completed if done early in the course, especially soon after the diagnosis. Research is needed to explore discussing genetic testing for the large proportion of patients who are terminally ill at diagnosis where genetic screening would potentially benefit the family members.
