Filter by:This is a prospective, multi-center observational study designed to address patient-reported nasal outcomes in adults undergoing endoscopic and microscopic surgical removal of pituitary tumors. The primary objective of this study is to determine the difference in nasal outcomes by using the Anterior Skull Base (ASK) Nasal survey between patients treated with endoscopic surgical technique and those treated with microscopic surgical technique. Patients will be given the ASK Nasal survey to assess their nasal functioning and overall health before their surgery, and at post-operative visits 1-2 weeks, 3 months, and 6 months.
Background: - Cushing s disease can be caused by a tumor of the pituitary gland, a small gland about the size of a pea located at the base of the brain. These tumors produce high levels of hormones, which cause obesity, diabetes, and growth problems. The cure for this type of Cushing s disease is to have surgery that removes the tumor but leaves the pituitary gland alone. Currently, magnetic resonance imaging scans are the best way to find these tumors. However, many of these tumors do not show up on the scan. - Positron emission tomography (PET) scans use radioactive chemicals to light up parts of the body that are more active, such as tumors. Researchers want to try to make the small Cushing s disease tumors more active to help them show up on the scans. A special hormone will be given before the scan to make the tumors more active. Objectives: - To test the use of hormone stimulation to improve brain scans for Cushing s disease tumors. Eligibility: - Individuals at least 8 years of age who will be having surgery to remove Cushing s disease tumors. Design: - Participants will be screened with a medical history, physical exam, blood and urine tests, and imaging studies. - They will have three brain scans before surgery. The first scan is a magnetic resonance imaging scan to show a full picture of the brain. The second and third scans are PET scans. - The first PET scan will be given without the special hormone. The second PET scan will be done more than 24 hours but less than 14 days after the first PET scan. The second PET scan will be given with the special hormone. - Participants will have tumor removal surgery through another study protocol.
This study will assess the effectiveness and safety of pasireotide long-acting release in patients who have rare tumors of neuroendocrine origin.
The purpose of this study is to investigate the treatment and natural history of acromegaly. We have a longstanding interest in acromegaly treatment, and a cohort that has been followed for 30 years, or more in some cases. We will continue to follow patients and recruit new patients for treatment and follow-up. Blood and pituitary tumor tissue (when available through clinical care) will be saved for future analyses related to acromegaly.
The purpose of this study is to compare the efficacy of Sandostatin LAR® (Registered Trademark) Depot to transsphenoidal surgery in previously untreated acromegalic patients with macroadenomas. The primary goal is to normalize insulin-like growth factor-1 (IGF-1) levels. Secondary goals are to compare Sandostatin LAR® (Registered Trademark) Depot treatment and transsphenoidal surgery to achieve the following goals: suppress growth hormone levels to less than or equal to 2.5 ng/mL, relieve the clinical signs and symptoms of acromegaly, reduce the size of the macroadenomas, produce few side effects, assess the prognostic value of baseline pituitary adenoma size, extension and baseline growth hormone level on post-treatment growth hormone and IGF-1 levels, and assess the resource utilization of each treatment type.
Presently, patients with primary malignant brain tumors have a life expectancy of 15 weeks following surgery unless they receive additional types of therapy (chemotherapy, radiotherapy, and/or immunotherapy). Patients that receive additional therapy can increase life expectancy to 50 weeks. The statistics on the life expectancy and survival have increased efforts among researchers to develop new treatments for primary malignant brain tumors. This research project involves the growth and study of human brain tumor cells outside the body in the laboratory as part of an attempt to better understand these tumors and to develop more effective treatments for them.
