CNS germinoma (brain germinoma)
Also called Central nervous system germinoma
A CNS germinoma is a germ-cell tumor arising in the brain, often near the pineal or suprasellar regions. Its location can affect fluid circulation, vision or hormone function. It is treated differently from nongerminomatous CNS germ-cell tumors.
Other names and abbreviations
CNS germinoma, intracranial germinoma, pineal germinoma, brain germ cell tumor, Intracranial germinoma, suprasellar germinoma
In short
- A CNS germinoma is a germ cell tumor in the brain, often near the pineal gland or above the pituitary, that can affect vision, hormones or brain fluid flow.
- It is usually treated with radiation, often with chemotherapy to help tailor how much radiation is given, plus hormone replacement or other support when needed.
- For some tumors that come back, high-dose chemotherapy may be followed by a return of the patient's own stem cells, which does not need a donor.

Where transplant fits
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. may be used with 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. for selected recurrent disease. It returns the patient’s own cells and is not routine first-line Coming from another person. In an allogeneic, or donor, transplant, the stem cells come from a relative or an unrelated volunteer whose cells are a close enough match to the patient's..
Treatment depends on the exact diagnosis, disease stage, prior treatment and the person’s health.
Key facts
- Who it affects
- CNS germinomas mainly affect children, adolescents and young adults.
- Usual treatment
- Treatment commonly uses radiotherapy, often with chemotherapy to help tailor radiation exposure. Tumor extent, markers and response guide the regimen. Hormone replacement and other neurological support may also be needed.
- 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 germinoma (brain germinoma) 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.
