Choroid Plexus Tumors

A choroid plexus tumor is a serious condition that needs to be treated by a multi-disciplinary team consisting of neurosurgeons, neuro-oncologists and radiation oncologists. Even with appropriate treatment, a fraction of patients die from this disease.

As with most tumors, our treatments are limited to three modalities: surgery, radiation and chemotherapy.


Surgical removal is the most effective treatment for choroid plexus tumors. Surgery often cures choroid plexus papillomas, and patients with choroid plexus carcinomas have improved outcomes when the tumors can be completely removed.

Choroid plexus tumors often contain many blood vessels. In some circumstances, surgery can be made safer if the blood supply to the tumor is closed, using a technique called embolization, before the actual surgery.


Aggressive chemotherapy, with or without high dose chemotherapy with stem cell rescue, is often used in patients with choroid plexus carcinomas. Several small studies appear to show this improves outcomes, especially in patients who were unable to have the tumor completely removed with surgery.


Radiation can be an effective treatment for choroid plexus carcinomas. However, high doses can be toxic to the developing brains of young children. Radiation therapy is often reserved for patients whose tumors have recurred after initial treatment, or for those with metastatic disease who do not respond to chemotherapy.
