3 Clinical Trials for Various Conditions
To learn if hypophysectomy (treatment of the pituitary gland) using a type of radiation treatment called stereotactic radiosurgery (SRS) can help to relieve cancer-related pain.
This is a prospective, randomized, blinded, sham controlled regional anesthetic (supra-orbital and infra-orbital nerve block) pain study to compare the systemic postoperative pain medication requirements in patients having Trans-sphenoidal Pituitary surgery. The patients will receive general anesthesia +/- regional anesthesia for trans-sphenoidal pituitary surgery and systemic pain medication during the intra-operative and postoperative (6hrs) period. The amount of systemic pain medication requirements will be compared between those patients receiving regional and general anesthesia versus general anesthesia alone.
This research is being done to see if a delivery of a single high dose of radiation therapy to a small area of the pituitary gland and pituitary stalk in a highly precise manner may be helpful in reducing intractable pain from bone metastases.
