Summary of

Nongerminomatous Germ Cell Tumors (NGGCTs)

Primary CNS GCTs are a heterogeneous group of neoplasms that are more common in Japan and other Asian countries than in North America and Europe. In North America, they account for approximately 4% of all primary brain tumors, with a peak incidence from age 10 years to age 19 years and a male predominance in a pineal location.[1-3]

CNS GCTs are broadly classified as germinomatous and nongerminomatous germ cell tumors (NGGCTs) on the basis of clinicopathological and laboratory features, including tumor markers.[4,5] An alternative therapeutic classification in Japan distinguishes three groups on the basis of their prognostication: good prognosis (e.g., germinoma), intermediate prognosis (e.g., teratoma with malignant transformation), and poor prognosis (e.g., yolk sac tumor, choriocarcinoma, embryonal carcinoma, and mixed tumors of those entities).[4]

You can access processed data today here by simply logging in to PedcBioPortal
You can request raw data by completing this form. The review normally takes 1 week. Once approved you can access the raw data by creating cohorts of interest on the Kids First Data Resource Portal and performing analysis on the cloud in Cavatica

Flash frozen tissue is tissue from a surgical procedure where the tissue is frozen instantly in liquid nitrogen to ensure there is no degradation

Tissue in freezing media is tissue from a surgical procedure where the tissue is frozen 1 degree at a time over a 24-hour period to keep the tissue intact and compatible with regrowing the tumor for testing

Matched blood is blood that is collected from the patient in addition to tissue from the tumor. This blood provides researchers a direct comparison between normal and tumor specimens for this specific patient

Cerebral Spinal Fluid (CFS) is fluid taken from the the nervous system that researchers can use to study brain tumors

Paternal and maternal specimens are specimens taken from the biological parents of the subject. These specimens provide researchers with the ability to compare tumor and normal tissue and predispositions
