Summary
Acromegaly patients have a significantly higher risk of developing colorectal polyps and cancer. Regular colonoscopies are recommended for early detection of these neoplastic lesions in the large bowel.
Area of Science:
- Endocrinology
- Gastroenterology
- Oncology
Background:
- Acromegaly is associated with an increased incidence of colorectal neoplastic lesions.
- Studies indicate a 3-fold higher prevalence of intestinal polyps and a 4-fold increased risk of colorectal cancer in acromegalic individuals.
Purpose of the Study:
- To highlight the increased risk of colorectal neoplasms in acromegaly.
- To emphasize the importance of early detection and surveillance for these lesions.
Main Methods:
- Prospective studies utilizing colonoscopy.
- Pancolonoscopy as the diagnostic procedure of choice for large bowel neoplasms.
Main Results:
- Acromegalic subjects exhibit a higher prevalence of both hyperplastic and adenomatous polyps.
- These polyps can be multiple, distributed throughout the colon, and sometimes associated with intestinal carcinomas.
- Pancolonoscopy demonstrates superior sensitivity and specificity compared to barium enema, fecal occult blood tests, and CEA levels.
Conclusions:
- Pancolonoscopy is recommended for surveillance in acromegaly patients for early detection of neoplastic lesions.
- Despite potential challenges in completion due to colonic anatomy, pancolonoscopy is crucial for managing colorectal cancer risk in this population.
