Childhood Extracranial Germ Cell Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Pediatric GCT Biology


There is very little data about the potential genetic or environmental factors associated with childhood extracranial GCTs. Patients with Klinefelter syndrome [22,23,24] are at increased risk for mediastinal GCTs, while patients with Swyer syndrome [25,26] are at increased risk for gonadoblastomas and germinomas.
