Outcomes of Universal Point-of-Care Genetic Testing in Diverse Patients With Pancreatic Ductal Adenocarcinoma
PURPOSE: Guidelines recommend all patients with pancreatic ductal adenocarcinoma (PDAC) undergo germline genetic testing (GT). Rates of recommendation and completion of GT among diverse patients with PDAC are not known. The aim was to determine rates of recommendation and completion of point-of-care GT in diverse patients with PDAC.
METHODS: A retrospective review of patients with PDAC seen at an academic center between April 2019 and December 2020 was performed. Recommendation, completion and results of point-of-care GT, and demographic and clinical factors were recorded. Univariate and multivariate analyses of GT were performed using the chi-square test and logistic regression.
RESULTS: In total, 579 patients with PDAC were included. The median age at diagnosis was 67 years; 52% were male; 63% were non-Hispanic White (NHW) patients, and 20% were African American (AA) patients. GT was performed in 216 (37%) patients. Of those tested, 47 (22%) had a pathogenic/likely pathogenic variant identified of which 25 (12%) were in PDAC-associated genes. On multivariate analysis, age, NHW race, personal and family cancer history, medical oncology visit, and number of visits were independent predictors of GT completion. AA patients had significantly lower rates of recommendation and completion of GT compared with NHW patients.
CONCLUSION: Point-of-care GT in patients with PDAC is unacceptably low, especially among AA patients. Testing disparity might be due to lack of provider recommendation more than patient uptake. Lack of testing leads to missed opportunities for potential targeted therapies, improved outcomes, and identification of at-risk family members who could potentially benefit from surveillance.
