Pineoblastoma
Pineoblastoma is a rare aggressive tumor of the pineal region of the brain. It can obstruct cerebrospinal fluid and spread within the central nervous system. Molecular subtype and age influence treatment and prognosis.
Other names and abbreviations
pinealoblastoma, pineal PNET, primitive neuroectodermal tumor of the pineal region, Pinealoblastoma, previously grouped with CNS primitive neuroectodermal tumours
In short
- Pineoblastoma is a rare, aggressive tumor in the pineal area of the brain that mainly affects children and can block brain fluid flow or spread within the brain and spine.
- Treatment generally combines surgery, chemotherapy and radiation suited to age, and very young children may get chemotherapy plans meant to delay radiation.
- Some intensive chemotherapy plans, especially for young children or tumors that come back, use a return of the patient's own stem cells, so no donor is normally needed.

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. is used in selected intensive chemotherapy protocols, particularly in young children or recurrent disease. It supports The soft, spongy tissue in the center of most bones. Red bone marrow holds the blood-forming stem cells that make red blood cells, white blood cells and platelets. recovery using the patient’s own cells; a registry donor is not normally part of treatment.
Treatment depends on the exact diagnosis, disease stage, prior treatment and the person’s health.
Key facts
- Who it affects
- Pineoblastoma mainly affects children, with age patterns varying by molecular subtype.
- Usual treatment
- Treatment generally combines surgery, chemotherapy and age-appropriate radiation. Very young children may receive chemotherapy approaches intended to delay radiation, and some protocols use high-dose chemotherapy.
- 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 pineoblastoma 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.
