Communicating the components of informed treatment decision-making in patients with pancreatic cancer receiving preoperative therapy.

147 Background: Preoperative therapy for localized pancreatic cancer represents an emerging treatment paradigm with the potential to provide significant benefits, yet with complex risks. Research is lacking about whether clinicians effectively communicate key components of informed decision-making for patients considering this treatment. Methods: From 2017-2019, we conducted a two-part, mixed methods study. In part 1, we conducted interviews with clinicians (medical/radiation/surgical oncology, n = 13) and patients with pancreatic cancer who had received preoperative therapy (n = 18) to explore perceptions of information needed to make informed decisions about preoperative therapy, from which we generated a list of key elements. In part 2, we audio recorded the initial multidisciplinary visits of patients with pancreatic cancer eligible for preoperative therapy (n = 20). Two coders (94% concordance) independently identified whether clinicians discussed key elements from part 1. Patients also completed a post-visit survey reporting whether clinicians discussed the key elements. We explored discordance between audio recordings and patient reports using qualitative, explanatory themes. Results: In part 1, we identified 13 key elements of informed treatment decision-making, including treatment logistics, alternatives, and potential risks/benefits. In part 2, recordings showed that most visits included discussions about logistics, such as the chemotherapy schedule (n = 20) and use of a port-a-cath (n = 20), whereas few included discussions about risks, such as the potential for hospitalizations (n = 7), urgent visits (n = 6), or needing help with daily tasks (n = 6). Patients reported hearing about potential benefits, such as likelihood of achieving surgery (n = 10) and cure (n = 7), even when these were not discussed. Qualitative themes across these discordant cases included clinician optimism regarding present day results versus historical findings and mentions of positive outcomes from prior patients without citing specific data or potential adverse outcomes. Conclusions: We identified key elements of information patients with pancreatic cancer need to make informed decisions about preoperative therapy. Although clinicians frequently disclosed much of this information, we found multiple cases of patient-clinician discordance for certain key elements, which underscores the need for interventions to enhance patient-clinician communication regarding pancreatic cancer treatment decisions.
