Guide for use: | Record the depth of myometrial invasion in millimetres (mm). The depth of myometrial invasion is assessed on microscopic examination and is measured from the normal endometrium-myometrium interface (not the surface of the intracavity or exophytic tumour) to the deepest tumour infiltrative focus. The depth of myometrial invasion cannot exceed the myometrial thickness. Myometrial thickness ranges from 2 to 40 mm. A myometrial thickness of 5 mm or less is considered to be normal. Depth of myometrial invasion is a prognostic factor for endometrial cancer. The fractional myometrial invasion by tumour cells, i.e. the ratio of myometrial invasive depth to total normal myometrial thickness, is predictive of lymph node metastases in high risk endometrial cancers. |
