A study of Johann et al. (2018), also endorsed by other researchers (Baiano et al., 2022; FUKUDA et al., 2021) proposed that sellar ATRT in adults resembles the ATRT-MYC pediatric profile which gives the opportunity of therapy individualization and supports the notion of sellar ATRT being a unique entity. This evidence concerns the gene MYC and atypical teratoid rhabdoid tumor.
