Summary

Stereotactic radiosurgery (SRS) offers a noninvasive treatment for Cushing disease, achieving remission in up to 90% of patients. While effective, potential complications include hypopituitarism, though SRS is comparable to surgery.

Area of Science:

  • Neurosurgery
  • Endocrinology
  • Radiation Oncology

Background:

  • Cushing disease, caused by pituitary adenomas, leads to hypercortisolism.
  • Current treatments include surgery, conventional radiotherapy, and stereotactic radiosurgery (SRS).

Purpose of the Study:

  • To review the indications, outcomes, and complications of SRS for Cushing disease.

Main Methods:

  • Review of literature on stereotactic radiosurgery for Cushing disease.

Main Results:

  • SRS achieves disease remission in up to 90% of patients.
  • Biochemical cure may be delayed up to 3 years; hypopituitarism is the most common complication (up to 50%).
  • SRS is noninvasive, with a low incidence of diabetes insipidus compared to surgery.

Conclusions:

  • SRS is an effective treatment for Cushing disease, with cure rates comparable to microsurgery.
  • SRS offers a noninvasive alternative to surgery, though long-term monitoring for hypopituitarism is necessary.
