CNS nongerminomatous germ cell tumor (NGGCT)
Also called Central nervous system nongerminomatous germ cell tumor
CNS nongerminomatous germ-cell tumors are a varied group of brain tumors that includes several germ-cell histologies and mixed tumors. Imaging, tissue when appropriate and tumor markers distinguish them from pure germinoma and other brain tumors.
Other names and abbreviations
CNS NGGCT, NGGCT, intracranial non-germinomatous germ cell tumor, CNS non-germinoma, brain germ cell tumor, Intracranial nongerminomatous germ cell tumour
In short
- CNS nongerminomatous germ cell tumors are a varied group of brain tumors, told apart from pure germinoma by scans, tumor marker tests and sometimes a tissue sample.
- Treatment usually combines several chemotherapy drugs with radiation, plus surgery for tumor that remains in some cases, based on markers, spread, tumor type and response.
- For some tumors that come back, or in specialist plans, high-dose chemotherapy may be followed by a return of the patient's own stem cells, with no donor needed.

Where transplant fits
Very strong drug treatment given in large doses, often to kill cancer cells. It also destroys the bone marrow and can cause other serious side effects. A stem cell transplant usually follows to rebuild the marrow. followed by Coming from the patient's own body. In an autologous transplant, the patient's own stem cells are collected and stored, then given back after high-dose treatment. It does not use a donor. can be considered in selected recurrent disease or specialist protocols. This uses the patient’s own cells; it does not require a registry donor, and benefit varies with disease context.
Treatment depends on the exact diagnosis, disease stage, prior treatment and the person’s health.
Key facts
- Who it affects
- These tumors mainly affect children, adolescents and young adults.
- Usual treatment
- Treatment usually combines multi-drug chemotherapy and radiotherapy, with surgery for selected residual disease. The plan depends on tumor markers, spread, response and the specific histology.
- Cells used in a transplant
- The patient’s own collected blood-forming cells for autologous stem cell rescue, when that procedure is appropriate.
- Where a donor fits
- Limited transplant role

Other patients are waiting for a match.
Most people with CNS nongerminomatous germ cell tumor (NGGCT) are treated without a registry donor. Many people with other blood cancers and blood disorders need a donor who is a stranger.
Join the registry
JBF points you to the official registry that serves your country. It explains who can join and what donation involves.
Help a family run a drive
If someone you love needs a donor, a registration drive can add many potential donors at once, for them and for others.
Support this work
Gifts to the Jada Bascom Foundation support donor-awareness education like this guide, community outreach, drive planning and referrals to official registries.
