Recurrence of craniopharyngioma occurs in approximately 35% of patients regardless of primary therapy. Management is determined in large part by prior therapy. Repeat attempts at gross total resection are difficult and long-term disease control is less often achieved.[Level of evidence: 3iiiDi] Complications are more frequent than with initial surgery.[Level of evidence: 3iiiDi] External-beam radiation therapy is an option if this has not been previously employed, including consideration...
Radiation therapy for postsurgical recurrence, which offers a high likelihood of local control.[1,2]
Reirradiation, which provides long-term local control and control of visual symptoms.
The question and selection of further treatment for patients who relapse is dependent on many factors, including the specific type of pituitary tumor, prior treatment, visual and hormonal complications, and individual patient considerations.
Treatment Options Under Clinical Evaluation for Recurrent Pituitary Tumors
Treatment options under clinical evaluation for recurrent pituitary tumors include the following:
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with recurrent pituitary tumor. 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.
