From: An update on the clinical diagnostic value of β-hCG and αFP for intracranial germ cell tumors
Scatter diagrams representing the relationship between synchronously sampled tumor markers in the cerebrospinal fluid (CSF) and serum. The tumors are classified as germinoma (GERM, red marks) and NGGCTs (green marks ). a Relationship between β-subunit of human chorionic gonadotropin (β-hCG) levels (n = 40, r = 0.852, P < 0.05). b Relationship between alpha fetoprotein (αFP) levels (n = 39, r = 0.788, P < 0.05)
