Radiation therapy for acromegaly is usually reserved for patients who have tumor remaining after surgery. These patients often also receive medication to lower GH levels. Radiation therapy may be given in divided doses over four to six weeks. This treatment lowers GH levels by about 50 percent over two to five years.
In selected patients, radiation therapy may be given as highly focused, single or multiple treatments. CyberKnife, proton beam, or gamma knife radiosurgery may be used for such treatment. Radiation therapy may cause a gradual loss of pituitary hormone levels over time, resulting in hypopituitarism. Loss of vision and brain injury, which have been reported, are very rare complications of radiation treatments.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
