The purpose of this study is to observe predictors of pituitary tumor recurrence and markers of persistent disease activity in patients harboring pituitary mass lesions of all types.
There is a variety of tumors affecting the pituitary gland in childhood; some of these tumors (eg craniopharyngioma) are included among the most common central nervous system tumors in childhood. The gene(s) involved in the pathogenesis of these tumors are largely not known; their possible association with other developmental defects or inheritance pattern(s) has not been investigated. The present study serves as a (i) screening/training, and, (ii) a research protocol. As a screening and training study, this protocol allows our Institute to admit children with tumors of the hypothalamic-pituitary unit to the pediatric endocrine clinics and wards of the NIH Clinical Center for the purposes of (i) training our fellows and students in the identification of genetic defects associated with pituitary tumor formation, and (ii) teaching our fellows and students the recognition, management and complications of pituitary tumors As a research study, this protocol aims at (i) developing new clinical studies for the recognition and therapy of pituitary tumors; as an example, two new studies have emerged within the context of this protocol: (a) investigation of a new research magnetic resonance imaging (MRI) tool and its usefulness in the identification of pituitary tumors, and (b) investigation of the psychological effects of cortisol secretion in pediatric patients with Cushing disease. Continuation of this protocol will eventually lead to new, separate protocols that will address all aspects of diagnosis of pituitary tumors and their therapy in childhood. (ii) Identifying the genetic components of pituitary oncogenesis; those will be investigated by (a) studying the inheritance pattern of pituitary tumors in childhood and their possible association with other conditions in the families of the patients, and (ii) collecting tumor tissues and examining their molecular genetics. As with the clinical studies, the present protocol may help generate ideas for future studies on the treatment and clinical follow up of pediatric patients with tumors of the pituitary gland and, thus, lead to the development of better therapeutic regimens for these neoplasms....
The researchers are doing this study to find out whether pasireotide is an effective treatment for people with prolactinoma who cannot receive dopamine agonist therapy. Another purpose of this study is to find out whether pasireotide is a safe treatment for people with prolactinoma.
This is a prospective, single-blinded, multicenter study evaluating the benefit of sinonasal irrigations following endoscopic pituitary surgery. The goal of this study is to create practice changing guidelines with objective data highlighting the importance of irrigations on postoperative outcomes for pituitary surgery.
This is a prospective longitudinal study to access postoperative 2-year quality of life in patients who undergo endonasal endoscopic approach surgeries of the skull base.
Background: Pituitary tumors can cause problems by secreting hormones in the body. They can also problems by growing large and pushing on organs near the pituitary gland. The best treatment for such tumors is to remove them by surgery. But that may be sometimes difficult. Some tumors maybe too small to see. Some other tumors maybe so large that portions maybe left behind during surgery. The endosphenoidal coil (ESC) is a new magnetic resonance imaging (MRI) device. It fits in a small space made during surgery near the pituitary. Researchers want to see if it helps transmit MRI signals during surgery to make better images of the pituitary gland and tumors. Objective: To test the safety of using a new coil device to improve MRI imaging of pituitary tumors during surgery. Eligibility: Adults 18-85 years old who are having pituitary tumor surgery at NIH Design: Participants will be screened with: * Medical history * Physical exam * Review of prior brain scans * Blood and pregnancy tests All participants will have MRI of pituitary gland. They will lie on a table that slides into a metal cylinder in a strong magnetic field. They will lie still and get earplugs for loud sounds. A dye will be inserted into an arm vein by needle. Participants will stay in the hospital for about 1 week. They will repeat screening tests. Participants will have standard pituitary surgery. They will get medicine to go to sleep. The surgeon will create a path to the pituitary gland from under the lip. During surgery, the ESC will be placed through the path to near the pituitary. Then an MRI will be done during surgery. Then the ESC will be removed and standard surgery will continue. Participants will get standard post-operative care under another protocol.
The primary objective of this study is to evaluate the diagnostic performance of the CONVIVO confocal endomicroscope in discriminating between normal and abnormal tissue in vivo during brain tumor surgery. The interpretation of intraoperative images obtained in situ will be tested against conventional histologic evaluation of targeted biopsies from imaged tissue. The study team hypothesize that there will be a high degree of correlation between images obtained with the CONVIVO system and conventional histologic interpretation.
Pleuropulmonary blastoma (PPB) is a rare malignant neoplasm of the lung presenting in early childhood. Type I PPB is a purely cystic lesion, Type II is a partially cystic, partially solid tumor, Type III is a completely solid tumor. Treatment of children with PPB is at the discretion of the treating institution. This study builds off of the 2009 study and will also seek to enroll individuals with DICER1-associated conditions, some of whom may present only with the DICER1 gene mutation, which will help the Registry understand how these tumors and conditions develop, their clinical course and the most effective treatments.
