Empowering multidisciplinary teams in cancer survivorship: Results from the ASCO Project ECHO survivorship program in Brazil.

11096 Background: As the number of cancer survivors increases in Brazil, access to structured survivorship education for health professionals remains limited. ASCO Project ECHO Survivorship Program was implemented to strengthen survivorship knowledge and care coordination among multidisciplinary teams. Methods: This longitudinal, virtual, case-based education series was conducted from September to December 2025. Intended audience included oncologists, general physicians, nurses, psychologists, and other professionals involved in survivorship care. Program consisted of 08 distinct, self-contained sessions, beginning with an introductory session on core survivorship principles, followed by cancer-specific survivorship topics delivered through short didactics and case discussions. Participants were encouraged to attend all sessions; however, each session was designed to be independent. Attendance was tracked, and final post-program survey assessed satisfaction and self-reported impact on clinical practice. Analyses focused on participants attending ≥4 sessions (≥50%), which was the criterion for certification and a pragmatic threshold to ensure meaningful engagement. Results: 161 health professionals attended at least one session, and 65 (40.4%) participated in ≥4 sessions. Participants represented diverse disciplines, including physicians and oncologists (31%), psychologists (13.7%), nutritionists (8.7%), pharmacists (6.2%), nurses (11.2%), and other professionals. Subsequent analyses were limited to participants attending ≥4 sessions. Among these,final survey response rate was 66.2%. Reported practice changes and satisfaction outcomes were collected through the post-program survey. Respondents described increased confidence in identifying and managing late and long-term physical effects, addressing psychosocial and sexual health concerns, improving interdisciplinary collaboration, and supporting transitions to post-treatment care. Overall satisfaction was high, with 97.7% reporting being satisfied or very satisfied. Despite high satisfaction, attendance declined across sessions, highlighting the need to better understand factors influencing sustained participation in longitudinal virtual education programs. Conclusions: ASCO Project ECHO Survivorship Program in Brazil demonstrated strong engagement and meaningful self-reported integration of survivorship principles into clinical practice among a multidisciplinary workforce. This flexible, scalable educational model supports survivorship capacity-building across diverse professional roles in middle-income settings. Further evaluation is needed to better understand factors associated with decreased attendance over time and to inform strategies that optimize sustained engagement in longitudinal survivorship education programs.
