Abstract INTRODUCTION Videoteleconference in neurooncology is feasible and sustainable. The well-established 20 years’ Sickkids/KHCC teleconferencing is an example. Since 2018, several regional centers joined these meetings to discuss their patients’ management plans. We aimed to evaluate the impact of this experience. METHODS We retrospectively reviewed the 56 meetings’ minutes (9/2018-12/2023) and compared the pre-conference suggested plans with the post-conference recommendations. We recorded if the recommendations were implemented and the impact perceived. RESULTS In total, 251 patients were discussed: KHCC (137) and non-KHCC (114). Four of the regional participating oncologists had dedicated pediatric neuro-oncology training. Patients were selected for discussion due to challenges in their management (i.e. with relapsed tumors, rare diagnoses, unexpected tumor behavior). Main diagnoses were: Low-grade-glioma (28%), High-grade-glioma (21%), and Medulloblastoma (17%). Of the 227 patients where the local team suggested a care plan, the teleconference recommendations concurred with the proposed plan in 50% of the cases, agreed on but provided an alternative plan option in 18% and disagreed on in 32% of the cases. The difference in recommendations mostly affected the proposed treatment modality (15%). In 64% of the discordant plans and 50% of the alternative plans, the treating team applied the recommendations. Challenges to apply the recommendations were mainly linked to patients’ factors (53%, plan refusal, traveling abroad, clinical deterioration), local multidisciplinary team consensus on a different plan (29%) or logistic difficulties (18%, e.g. drug access). CONCLUSIONS Improvement in patients’ care was likely achieved with the continuous effort of the local teams to implement the recommendations. Participating oncologists valued the shared educational experience learned from each other’s case discussions, especially those related to molecular-testing and implications on treatment. Joining such regional teleconferences is of particular importance to small-volume centers or those lacking a pediatric neurooncologist. Regional and international collaborations are a necessity when it comes to improving the care of children with CNS tumors.
