Introduction: Medulloblastomas are the most common solid tumors of childhood and classified into 4 molecular subgroups: WNT, SHH, Group 3 and Group 4. Many studies seek to develop new chemotherapy drugs for medulloblastomas by identifying genes whose expression is new molecular targets for drugs, such as membrane receptors associated with cell replication. Objective: To evaluate the association of CD114 expression with mortality in patients with medulloblastoma. Methods: Review carried out collecting information published on virtual platforms in Portuguese and English. Initially, a search was carried out for descriptors related to the topic - neurosurgery, surgical oncology, molecular targeted therapy and medulloblastoma, with AND or OR search, considering the title and/or summary. Afterwards, only those that were most related to the topic were included, and the texts read in full. Finally, 23 articles were referred. Results: There is a difference in the expression of the CD114 membrane receptor between Group 3 and the other molecular groups, in addition to a difference between the SHH γ molecular subtype and the Group 3 α and Group 3 β molecular subtypes. There was no statistically significant difference between the other groups and subtypes. Regarding mortality, this review did not demonstrate statistical significance in the relationship between low and high expressions of this gene and mortality. Conclusion: There is no direct relationship between the expression of the CD114 membrane receptor and mortality in patients with medulloblastoma. However, additional studies are needed on the intracellular signaling pathways associated with this receptor and its gene, CSF3R.
