Despite the availability of healthcare and community services dedicated to cancer survivors, these remain underutilized by young adults living with cancer (YAC; aged 18-39). A workshop was organized in Montréal, Canada, to identify the needs of YAC during their post-treatment transition period and explore existing services dedicated to YAC. We recruited seventeen stakeholders (N = 17), including seven YAC, to participate in a one-day workshop to consult about best approaches and practices to meet the needs of YAC, post-treatment. All discussions were transcribed, and a thematic qualitative analysis was performed. Two main findings were identified: differences and similarities among stakeholders about perceptions of post-treatment needs; and suggestions to meet YAC needs following treatment. Results demonstrate the importance of collaboration among multiple stakeholders, including YAC, when designing services for YAC. Results include suggestions to improve services available through community or healthcare centres.
