简要总结
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.
详细描述
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 Irving Medical Center.

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.

结局指标
主要结局
Percentage of patients that have received surgery as first line therapy
时间窗: At 5 years of therapy
Frequency of each type of acromegaly therapy and rates of treatment by surgery alone, somatostatin analog, pegvisomant, radiotherapy and combinations of each of these therapies in the cohort will be recorded and determined. The expected result is that more than 90% of our cohort has received surgery as first line therapy and only a minority has received primary medical therapy.
次要结局
- Number of patients with IGF-1 levels remaining elevated(At 5 years of therapy)
- Sleep Apnea Rate(At 5 years of therapy)
- Hypertension Rate(At 5 years of therapy)
- Diabetes Mellitus Rate(At 5 years of therapy)
