The Patient Centered Outcomes Research Institute (PCORI) requires engagement of patient stakeholders. There is limited description of both the context and the processes used to engage patients effectively. This paper discusses engagement activities, roles and responsibilities, value of a Patient Advisory Board (PAB), and lessons learned. Data include program notes, research team reflections, PCORI reporting, and an advisor survey.Facilitators of meaningful engagement included creating a learning community, co-defining clear roles, reimbursing advisors, establishing clear avenues for communication, and welcoming unique contributions. Lessons learned were the value of time, the importance of building trust, and the benefits of diverse perspectives. The approach to meaningful engagement of patient advisors in research has the potential to enhance the relevance and usefulness of research for improving lives.Tumor immunity is closely associated with the prognosis of tumors, including osteosarcoma (OS). The aim of the present study was to construct an immune-related prognostic index (PI) to predict the prognosis of OS. Herein, OS expression data were sourced from the Therapeutically Applicable Research to Generate Effective Treatments (TARGET) database. We divided the OS patients into nonmetastatic and metastatic groups, allowing differentially immune-related genes (DIRGs) to be selected. After DIRGs were further investigated by enrichment analysis, four keys prognostic IRGs (CD79A, CSF3R, MTNR1B and NPPC) were identified using a Cox proportional hazards model. Then, an immune-related prognostic index was constructed. Finally, gene set enrichment analysis (GSEA) was employed to further explore the underlying mech
