Surveillance for Pancreatic Cancer: Knowledge, Motivations, Barriers, and Preferences Among High-Risk Individuals and...

IntroductionSurveillance of at-risk populations for pancreatic ductal adenocarcinoma (PDAC) is a potential strategy to reduce its incidence and improve its prognosis. However, there is considerable debate about who should participate and relatively little information about how people perceive different testing options.MethodsUsing the Health Belief Model as a framework, this qualitative, observational study including eleven focus groups and seven interviews, summarizes the knowledge, motivations, barriers and preferences for PDAC surveillance in underserved populations with low cancer screening rates and for high-risk individuals (HRI).ResultsHRIs have a high motivation to participate in PDAC screening and perceive few barriers to engage. Participants from underserved populations had little knowledge of PDAC and surveillance, but they were interested in surveillance for PDAC based on their perception of the benefits of cancer screenings. The main barriers for participation in PDAC surveillance programs were cost, distrust of the larger medical system, discomfort associated with the testing, lack of a provider's recommendation, and fear of a positive result. These barriers varied based on a person's race/ethnicity and geographic location (urban vs. rural). Preferences expressed by underserved populations suggest that tests for early PDAC detection will need to be accurate, no or low cost, minimally invasive, and convenient to access. There was a correlation between a person's self-perceived susceptibility for PDAC and their willingness to tolerate more invasive and less convenient methods. In addition, participants were motivated to participate in early detection programs with clear guidelines accompanied by their doctor's recommendations.ConclusionThere appears to be an association between actual and perceived risk of PDAC and patient willingness to participate in an early detection program. For populations lower along the risk spectrum, there is limited knowledge about pancreatic cancer or its risk factors, and potentially significant barriers to participate in an early detection program if deemed eligible.
