GERM-20. NEUROENDOSCOPIC BIOPSY OF INTRACRANIAL GERM CELL TUMORS: ACCURACY AND COMPLICATIONS

Intracranial germ cell tumors.

Intracranial germ cell tumors are a heterogeneous group of lesions which occur in children and adults. Within the classification of intracranial germ cell tumors, there are a variety of different tumor types which carry different prognoses. The diagnosis of an intracranial germ cell tumor usually requires histological information, but a subgroup of tumors will secrete specific tumor markers, in...

CT of pineal tumors and intracranial germ-cell tumors.

We reviewed 59 cases of pineal tumors and intracranial germ-cell tumors. Most pineal tumors occurred in the first three decades of life, with the exception of pineocytomas, which were seen at a mean age of 34. A male preponderance was noted in the various pineal tumors, except for pineocytomas. The most common tumor of the pineal region was germinoma, which usually showed high density with homo...

Diagnostic Imaging of Intracranial Germ Cell Tumors: A Review

genetics of testicular germ cell tumors

testicular germ cell tumor (tgct) is the most solid tumor in 20-40 years old man. tgct account for 95% of testicular tumors and represent a unique type of human cancer from several different perspectives. tgct arise by transformation of germ cells. the transformed germ cells exhibit ploripotentially to differentiate into embryonic. extra-embryonic, and somatic tissue types, and are highly sensi...

Germ Cell Tumors Gc-01. the Treatment for Histologically Unconfirmed Intracranial Germ Cell Tumors: Experience of 38 Cases

Between May 2002 and August 2010, a total of 38 patients, who were clinically diagnosed as, but without surgical biopsy confirmation, intracranial germ cell tumors (GCTs) were treated at our Cancer Center. The patients were grouped into chemotherapy(n 1⁄4 21 ), radiotherapy(n 1⁄4 5), and stereotactic radiotherapy (n 1⁄4 12) based on the primary treatment. Median age of the patients at diagnosis...
