A randomized, double-blind, placebo-controlled intervention trial involving 100 treated subjects undergoing endonasal trans-sphenoidal (ENTS) resection of pituitary lesion. Subjects will be randomized into two groups: 50 treated in the opioid-sparing arm and 50 treated in the standard post-operative medication arm.

Several studies showed that radiotherapy as brain tumors treatment may affect cognition. It was observed that durable memory impairments could arise at irradiated patients if radiotherapy is applied on medial temporal lobes. However, results concerned studies of anterograde memory and none, this day, estimates the impact of radiotherapy on autobiographical memory which also involves hippocampus. The aim of this study is to evaluate effects of cavernous sinus or sellar region irradiation on autobiographical memory. Thirty 35 to 65 years old patients, with cavernous sinus meningioma or pituitary adenoma for who radiotherapy is indicated will be recruited.

Delayed post-operative hyponatremia occurs in 5-20% of patients following pituitary surgery and typically occurs on post-operative day 5-10.This decline in sodium can occur rapidly and have serious consequences such as altered mental status, seizures, coma, and even death. Despite significant research into patient demographics and risk factors, the investigators have not been able to predict which patients will suffer from delayed post-operative hyponatremia to date. At the Barrow Neurological Institute, physicians currently utilize an outpatient screening protocol to monitor patients' sodium levels after surgery, but this has yet to be effective for reducing readmissions following pituitary surgery. The etiology of delayed post-operative hyponatremia has been linked to water and sodium dysregulation in the post-operative period. It has been shown that post-operative day 1-2 sodium levels are statistically lower in patients who develop delayed hyponatremia, however, the numerical differences are not large enough to guide clinical management. The investigators propose that a water load on post-operative day 1 may expose underlying sodium/water dysregulation in the early post-operative period. This would improve physicians' understanding of the pathophysiology of post-operative hyponatremia, and it may help to serve as a screening tool for these patients in the future.

A number of studies have compared the effects of total intravenous anesthesia(TIVA) versus inhalational anesthesia on perioperative period during transsphenoidal surgery. However, they have limitations especially for the phase of recovery after anesthesia: a fragmentary assessment. Quality of Recovery 40 (QoR-40) questionnaire was multi-dimensionally designed to assess the degree of recovery, specially after anesthesia and surgery. In this study, the investigators aim to compare the quality of recovery after inhalational anesthesia and after TIVA through QoR-40 questionnaire in patients undergoing transsphenoidal surgery for pituitary tumor under general anesthesia.

Many types of cancers overexpress a receptor for the vitamin folate (Folate Receptor). This Phase 2 study will utilize a standard imaging radionuclide, technetium-99m, conjugated to a ligand (EC20) designed to bind to the folate receptor. The study is designed as an open-label, baseline-controlled study.

This is a randomized, multicenter trial with stratification done by a single radiologist at the coordinating center (NYU), and patients with comparable disease will be randomized to Sandostatin LAR treatment administered 1 time per month by IM injection for 3 months before (Arm A) or, for non-cured patients, after (Arm B) surgery. All patients will undergo transsphenoidal hypophysectomy. The impact of surgical debulking on responsiveness to Sandostatin LAR will be evaluated.The primary objective of this trial will be to determine whether surgery (debulking of pituitary adenomas) improves the response of patients with acromegaly to treatment with Octreotide LAR, when compared to Octreotide LAR therapy alone.

To study the in vivo expression of dopamine D2 receptors in nonfunctioning pituitary adenoma and the predictive role of dopamine dopamine D2 receptors PET-MR imaging in the therapeutic effect of dopamine agonists（DA）.

Headache is a very common main complaint of patients with GH pituitary tumor, which has seriously affected the normal work and life of patients. Although the current surgery and drugs have a certain effect on patients with headache, the overall effect is not satisfied. However, the use of COX-2 inhibitors, non-steroidal anti-inflammatory drugs and other analgesics are only effective for some patients with headaches, and long-term use has adverse reactions. Therefore, it is necessary to seek new treatments for postoperative headaches in patients with GH pituitary tumors. Transcranial magnetic stimulation (TMS) modulates the excitability of the underlying cerebral cortex by applying a rapidly changing magnetic field on the surface of the scalp. It is a relatively simple and safe method. It is currently approved for treating depression, migraine, obsessive-compulsive disorder, and Alzheimer's disease. Several small clinical studies have proven that rTMS can be used to prevent and treat Headache. Therefore, this study aims to observe the efficacy and safety of TMS in the treatment of postoperative headache in patients with GH pituitary tumors.

The purpose of this study is to collect information from medical records to see what effects proton beam radiation has on pituitary tumors and analyze possible side effects.
