parametrial involvement
Extension of cervical cancer into the lateral connective tissue surrounding the cervix and upper vagina.
Full Definition
Parametrial involvement refers to the lateral extension of cervical carcinoma beyond the cervix into the parametrium, the connective tissue that surrounds the cervix and upper vagina. This finding indicates locally advanced disease and significantly impacts staging and treatment planning. Parametrial invasion can be assessed clinically through pelvic examination, though MRI provides more accurate evaluation of the extent of parametrial infiltration.
Usage
Usage note: Critical for FIGO staging; distinguish from paracervical structures.
