This is a human, prospective and retrospective, single-center study of patients who have undergone treatment for acromegaly in New York City since 1981. The project will characterize, among other factors, the treatment methods received by patients, who administered the treatments and the success of this therapy in terms of biochemical control.
The first phase of this study will be to contact all subjects in the cohort by a mailing introducing them to the study. This will be followed by a phone call and administration of a questionnaire by phone or by mail. The questionnaire will collect current information on acromegaly treatment, morbidities other relevant history. Subjects will provide verbal consent to participate in this questionnaire part of the study and review of their medical records by the Principal Investigator (PI) and study staff.
In the second phase of the study, subjects will be invited to come for a visit that will be conducted by the PI and study staff at the Pituitary Center of Columbia University Medical Center. At this visit written informed consent will be obtained. The investigators will review the subjects' medical history that is obtained from the subject and review any records and laboratory test results provided by the subject and conduct clinical and laboratory assessments. Although all subjects participating in Phase 1 will be invited to participate, it is estimated that 120 of the subjects invited will come for the one visit over the 2-year time frame of this study.
In the third phase of the study a chart review for collection will be conducted and all data will be compiled. All subjects agreeing to participate, both in person and by mail, a chart review of all relevant patient data including demographic, clinical, biochemical, surgical and follow up information. Data from questionnaires and record reviews will be compiled for analysis.

We will compare the features of 3D stereophotography of acromegaly patients with that of healthy people. We hope to develop a computerized model to help screening acromegaly patients for e...
The aim of the study is to investigate sleep apnea, circulation and metabolism in acromegaly before and after surgery and/or medical treatment.
The purpose of this study is to investigate whether 6 months preoperative treatment with the somatostatin analogue octreotide improves the surgical outcome in patients with acromegaly.
Currently, the first line treatment for acromegaly is surgery, in order to remove the adenoma causing overproduction of growth hormone which leads to acromegaly. Octreotide LAR is approved...
Prevalence of sleep apnea syndrome in patients with acromegaly is about 70%. It seems that comorbidities of arterial hypertension or type 2 diabetes are more severe in patients with acrome...
Acromegaly is a chronic systemic disease with many complications and is associated with increased mortality when not adequately treated. Significant advances in acromegaly treatment, as well as in the...
Acromegaly has been associated with increased risk of cancer morbidity and mortality, but research findings remain conflicting and population-based data are scarce. We therefore examined whether patie...
Uncontrolled acromegaly is associated with increased morbidity and mortality. Despite multimodal therapeutic options, adequate control can be challenging and lead to prolonged exposure to growth hormo...
Diabetes and hypertension are frequent comorbidities of acromegaly.
Prevalence of papillary thyroid cancer (PTC) is increased in patients with acromegaly. We aimed to determine the protein expression of BRAF, RAS, RET, insulin like growth factor 1(IGF1), Galectine 3, ...
The presence of an excessively large tongue, which may be congenital or may develop as a result of a tumor or edema due to obstruction of lymphatic vessels, or it may occur in association with hyperpituitarism or acromegaly. It also may be associated with malocclusion because of pressure of the tongue on the teeth. (From Jablonski, Dictionary of Dentistry, 1992)
A pituitary tumor that secretes GROWTH HORMONE. In humans, excess HUMAN GROWTH HORMONE leads to ACROMEGALY.
A condition caused by prolonged exposure to excessive HUMAN GROWTH HORMONE in adults. It is characterized by bony enlargement of the FACE; lower jaw (PROGNATHISM); hands; FEET; HEAD; and THORAX. The most common etiology is a GROWTH HORMONE-SECRETING PITUITARY ADENOMA. (From Joynt, Clinical Neurology, 1992, Ch36, pp79-80)
A benign tumor, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes. Such pituitary tumors may give rise to excessive secretion of growth hormone, resulting in gigantism or acromegaly. A specific type of acidophil adenoma may give rise to nonpuerperal galactorrhea. (Dorland, 27th ed)
A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES.
