Expression of epithelial cadherin and cavernous sinus invasion in human pituitary adenomas.
Pituitary adenomas generally are regarded as benign tumors, although some invade the cavernous sinus and recur. We examined the epithelial cadherin (E-CD) expression in 30 pituitary adenomas (6 with cavernous sinus invasion and 24 without). Immunoreactivity of E-CD were found in all pituitary adenomas but they were very various. The presence of an association between E-CD expression and cavernous sinus invasion was assessed. There were no significant differences in E-CD expression between invasive and noninvasive adenomas. These results suggest that E-CD expression is not associated with cavernous sinus invasion in pituitary adenomas.
