Presentation
The present review summarizes the current knowledge on clinical presentation, diagnosis and prognosis. Tumors secreting GHRH are neuroendocrine tumors, usually well differentiated and mainly from pancreatic or bronchial origin. [semanticscholar.org]

Colonoscopy
- Polyps
Most studies suggest that as many as 30% of patients may have a premalignant colon polyp at diagnosis and that as many as 5% may have a colonic malignancy. [21] In studies, polyps were generally multiple and proximal to the splenic flexure, making them [emedicine.medscape.com]
As colon cancer may be the consequence of colon polyps degeneration, many studies have been done to assess the prevalence of colon polyps in patients with acromegaly. [ncbi.nlm.nih.gov]

Prognosis
The present review summarizes the current knowledge on clinical presentation, diagnosis and prognosis. Tumors secreting GHRH are neuroendocrine tumors, usually well differentiated and mainly from pancreatic or bronchial origin. [semanticscholar.org]
(See Prognosis, Treatment, and Medication .) [emedicine.medscape.com]
High GH/IGF-I concentrations, arterial hypertension, and cardiomyopathy are factors in a poor prognosis, while the duration of symptoms and other factors (diabetes, lipid disorders and cancer) are less important [ 30 ]. [ncbi.nlm.nih.gov]
Etiology
(See Pathophysiology and Etiology .) GH acts indirectly, by stimulating the formation of IGF hormones (also called somatomedins). [emedicine.medscape.com]
Etiology [ 34, 35 ] Acromegaly of pituitary origin More than 95% of patients with acromegaly have a benign monoclonal pituitary adenoma which develops from the somatotrope cells that normally produce GH in the pituitary. [ncbi.nlm.nih.gov]

Treatment is aimed at correcting (or preventing) tumor compression by excising the disease-causing lesion, and at reducing GH and IGF-I levels to normal values. Transsphenoidal surgery is often the first-line treatment. [ncbi.nlm.nih.gov]
