For adjuvant radiation decision making purposes, how is the "Lower Uterine Segment" (LUS) defined?
Is this a clinical/radiographic or strictly pathologic diagnosis?
Specifically, what is considered the superior/top border of LUS?
Answer from: Radiation Oncologist at Community Practice
We have always used the pathologist's description of LUS (fundus, body, LUS, and cervix). That being said, I don’t use LUS as risk factor for deciding adjuvant treatment except in borderline cases where may lean towards brachytherapy if otherwise a candidate for observation.
