Childhood Craniopharyngioma Treatment (PDQ®)

Recurrent Childhood Craniopharyngioma Treatment

Treatment Options for Recurrent Childhood Craniopharyngioma

Recurrence of craniopharyngioma occurs in approximately 35% of patients regardless of primary therapy.[1]

Treatment options for recurrent childhood craniopharyngioma include the following:

  1. Surgery.
  2. Radiation therapy, including radiosurgery.
  3. Intracavitary instillation of radioactive P-32, bleomycin, or interferon-alpha, for those with cystic recurrences.
  4. Systemic interferon.

The management of recurrent craniopharyngioma is determined largely by previous therapy. Repeat attempts at gross-total resections are difficult, and long-term disease control is less often achieved.[2][Level of evidence: 3iiiDi] Complications are more frequent than with initial surgery.[3][Level of evidence: 3iiiDi] If not previously employed, external-beam radiation therapy is an option, to include consideration of radiosurgery in selected circumstances.[4][Level of evidence: 3iiiDiii]

Cystic recurrences may be treated with intracavitary instillation of varying agents via stereotactic delivery or placement of an Ommaya catheter.[5] These agents have included radioactive P-32 or other radioactive compounds,[6,7]; [8][Level of evidence: 2A], bleomycin,[9]; [10][Level of evidence: 3iiiDiii] or interferon-alpha.[11]; [12][Level of evidence: 3iiiB] These strategies have been found to be useful in certain cases, and a low risk of complications has been reported. However, none of these approaches have shown efficacy against solid portions of the tumor.

Although systemic therapy is generally not utilized, a small series has shown that the use of subcutaneous pegylated interferon alpha-2b to manage cystic recurrences can result in durable responses.[13][Level of evidence: 3iiiDiii]

Treatment Options Under Clinical Evaluation for Recurrent Childhood Craniopharyngioma

The following is an example of a national and/or institutional clinical trial that is currently being conducted. Information about ongoing clinical trials is available from the NCI Web site.

  • PBTC-039 (NCT01964300) (Peginterferon Alfa-2b in Treating Younger Patients With Craniopharyngioma That is Recurrent or Cannot Be Removed By Surgery): This is a phase II clinical trial evaluating how well peginterferon alfa-2b works in treating children with craniopharyngioma that is recurrent or cannot be removed by surgery. This trial follows a small (N = 5) single-institution experience with peginterferon alfa-2b, in which prolonged complete responses were observed in some patients.[13]
