Recurrence is not uncommon in both low-grade and malignant childhood brain tumors
and may occur many years after initial treatment.[1] Disease may occur at the
primary tumor site or, especially in malignant tumors, at noncontiguous central
nervous system (CNS) sites. Systemic relapse is rare but may occur. At time of
recurrence, a complete evaluation for extent of relapse is indicated for all
malignant tumors and, at times, for lower-grade lesions. Biopsy or surgical
re-resection may be necessary for confirmation of relapse; other entities,
such as secondary tumor and treatment-related brain necrosis, may be clinically
indistinguishable from tumor recurrence. The need for surgical intervention
must be individualized based on the initial tumor type, the length of time
between initial treatment and the reappearance of the lesion, and the clinical
picture.
Childhood Central Nervous System (CNS) Atypical Teratoid/Rhabdoid Tumor
Refer to the PDQ summary on Childhood Central Nervous System Atypical Teratoid/Rhabdoid Tumor Treatment for more information.
Childhood Brain Stem Glioma
Childhood brain stem gliomas include:
- Diffuse intrinsic pontine gliomas.
- Focal or low grade brain stem gliomas.
Refer to the PDQ summary on Childhood Brain Stem Glioma Treatment for more
information.
Current Clinical Trials
Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with recurrent childhood brain stem glioma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
CNS Tumors in Children Aged 3 Years and Younger
Studies have addressed the treatment of infants who have progressive disease in
spite of chemotherapy. Approaches that have been used include further surgery,
chemotherapy, local and/or craniospinal radiation therapy, high-dose chemotherapy
supported by autologous stem cell rescue, or combinations of chemotherapy and
radiation therapy. Overall salvage rates have been less than optimal, but a
subgroup of children, primarily those with localized disease at the time of
relapse, may experience prolonged disease control and possible cure with
treatment after recurrence.[2-7] For children aged 2 years and younger, the use of high-dose craniospinal irradiation has been associated with poor neurocognitive outcome. Treatment for young children with multiple
recurrent and/or disseminated brain tumors is even more problematic and entry
into phase I and phase II trials is indicated to identify more effective and less
toxic agents.
Childhood CNS Embryonal Tumors
Childhood CNS embryonal tumors include:
Refer to the PDQ summary on Childhood Central Nervous System Embryonal Tumors Treatment for more information.
Childhood CNS Germ Cell Tumors
Childhood CNS germ cell tumors include:
- Germinomas.
- Embryonal yolk sac tumors.
- Choriocarcinomas.
- Immature teratomas.
- Mature teratomas.
- Teratomas with malignant transformation.
- Mixed germ cell tumors.
- Nongerminomatous germ cell tumors.
Germ cell tumors may be chemoresponsive. Patients may benefit from the types
of agents that are used to treat germ cell tumors in other locations; these agents include cisplatin, etoposide, and cyclophosphamide. Patients with recurrent germ cell tumors for whom the
standard chemotherapy options have failed may be entered into phase I and phase
II studies that are designed to determine the activity and toxic effects of
agents new to the treatment of this tumor.
Current Clinical Trials
Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with childhood central nervous system germ cell tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

Childhood Ependymoblastoma
Refer to the PDQ summary on Childhood Central Nervous System Embryonal Tumors Treatment for more information.
Childhood Low-Grade Glial Tumors
Surgical resection, radiation therapy (especially if not previously given),
and chemotherapy may result in prolonged disease stabilization for children
with recurrent low-grade tumors. Resection is an option for those patients
with a surgically accessible lesion and has the advantage of documenting the
histology of the recurrent tumor. Radiation therapy, if not previously given,
may result in tumor shrinkage and long-term disease control.
Chemotherapy with drugs such as carboplatin and vincristine has recently been
shown to result in tumor shrinkage and disease control for children with
low-grade glial neoplasms.[8] Similar results have been demonstrated for
hypothalamic and chiasmatic tumors treated with etoposide.[9] Entry into phase
I and phase II trials is indicated to identify more effective and less toxic
agents.
Childhood Medulloblastoma

Childhood Spinal Cord Tumors
At the time of recurrence, low-grade spinal cord glial tumors can be
treated with re-resection with or without the use of radiation therapy.
Recurrent low-grade and high-grade tumors which cannot be re-resected can be
treated on protocols designed for histologically similar brain tumors.
