The impact of immunotherapy education on GI cancers.

Abstract

479 Background: Gastrointestinal (GI) cancers are a heterogeneous group of cancers with varying underlying pathophysiology and distinct treatment paradigms. Immunotherapy (IO) is unique in each of the subtypes and biomarkers utility varies. With the expansion of IO in each cancer subtypes, education remains essential to optimize patient outcomes through integration of the latest evidence-based data at point of care. Through the partnership between Medscape Oncology and the Society for Immunotherapy of Cancer, 2 educational activities were designed to increase the knowledge and competence of oncologists surrounding the role of IO in patients with advanced GI cancers. Methods: The 2 educational activities included a text based online activity with 3 chapters focused on gastroesophageal cancers, colorectal cancers, and hepatocellular carcinoma (HCC) and a 30-minute online, video discussion with 3 faculty and synchronized slides on HCC. Educational effectiveness was assessed with repeated paired pre/post assessment where learners served as their own controls. A chi-square test was used to identify statistical significance in proportion of correct responses. The first activity launched 11/27/2019 and the second activity launched on 5/8/20. Data were collected and reported through 8/25/2020. Results: A total of 8433 learners, including 1543 oncologists, participated from 11/2019 through 8/2020. Participation in education resulted in significant relative improvements among oncologist learners on IO in GI cancers in (n = 641): 110%: role or eligibility of immune checkpoint inhibitors (ICIs) (p < .001) 38%: clinical trial data of ICIs (p < .001) Subsequent education on unresectable HCC demonstrated a significant relative improvement in both knowledge and competence for oncologist learners (n = 902): 19%: regarding clinical trial data in unresectable HCC (p = .073) 19%; competence identifying role of ICIs in unresectable HCC (p < .05) 59%: competence managing irAEs in unresectable HCC (p < .001). Conclusions: These 2 online CME-certified educational activities resulted in statistically significant gains in oncologist knowledge surrounding the use of IO in advanced GI cancers Follow-up education on HCC demonstrated the value and benefit of multi-modal and sequential activities on improving competence among oncologists caring for patients with unresectable HCC There remains a need for continuous education as more oncologists utilize IO in their practice while the understanding and availability of clinical data continues to expand and evolve in the varying GI cancer subtypes. More than 50% of learners continued to demonstrate a need in understanding the clinical trial data or role of IO in metastatic GI cancers with more than 40% of the learners demonstrating continued need on clinical trial data or role of IO in HCC specifically.
