Core Tip

Core Tip: Colorectal adenomas are benign, but premalignant lesions of the large intestine, as dysplasia may progress over time and result in the occurrence of colorectal carcinoma. The risk of progression is increased in adenomas with high-grade dysplasia. There are several risk factors for adenomas with high-grade dysplasia, of which energy imbalance and metabolic syndrome are increasing in importance because of their rising prevalence. Ghrelin is an adipokine important in energy balance and its expression was investigated in different tumors and tissues. With this prospective observational study we gained new insight on the expression and role of ghrelin and ghrelin receptor in colorectal adenomas.
