Adolescents and Young Adults with Primary Brain Tumor: Description of the Care Pathway of Patients Diagnosed in Grenoble Between 2013 and 2019.

Purpose: This study was undertaken to describe the Adolescents and Young Adults' (AYA-aged patients') neuro-oncology care pathways at Grenoble Alpes University Hospital according to the French health recommendations. Methods: A retrospective monocentric observational study was conducted between 2020 and 2021, on patients 13-29 years of age, diagnosed from January 2013 to 2019 in our institute with a primary brain tumor, excluding meningiomas, schwannomas, and neurinomas. The detailed analysis took into account the type of care unit (adult or pediatric), whether or not a dedicated AYA support team was involved, and various pretherapeutic actions. Results: Sixty patients were included in this study. Three of the 9 key stages of the care process were completed regardless of the type of management. Management in a pediatric oncology department seems to improve multidisciplinary discussions and access to the AYA team. Collaboration with an AYA team seems to improve the recourse to pediatric advice and supportive care. Conclusions: Increased vigilance at all key steps as defined in the recommendations of the Directorate General of Healthcare Services would significantly improve the overall quality of care for this specific population. In the absence of a dedicated AYA hospitalization unit, interdisciplinary cooperation between the different professionals of the adult and pediatric services is essential, and the involvement of the AYA mobile team is a factor that favors links and exchanges and ultimately an overall improvement in patient care and life. We propose our vision of an ideal AYA neuro-oncology care pathway.
