Primary CNS germ cell tumors are a heterogeneous group of neoplasms. The incidence of these tumors depends on the geographical location. The risk of CNS GCT is two to threefold higher in Asian / Pacific Islanders compared to Americans. Factors affecting the treatment and prognosis of diseases are the histological characteristics of the tumor, the presence or absence of distal metastases and the level of tumor markers in plasma and CSF. Currently, the most effective treatment option is neoadjuvant chemotherapy followed by a reduced dose and volume of radiation therapy. Depending on the histological characteristics of the tumor, treatment can provide a survival rate of up to 90%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
