Endometrial carcinoma Stage IB refers to tumors localized to the body of the uterus, where tumor infiltration is less than half of the myometrium. Surgical treatment is feasible for this stage and involves a slightly extensive total hysterectomy coupled with bilateral adnexectomy. During the surgery, a frozen section pathology test should be conducted. If the pathology report from the frozen section indicates special types of endometrial-like cancer, including papillary serous adenocarcinoma, clear cell carcinoma, squamous cell carcinoma, carcinosarcoma, and undifferentiated carcinoma, additional procedures are required. Moreover, if enlarged para-aortic or common iliac lymph nodes are palpated during the surgery, lymphadenectomy of the pelvic and para-aortic lymph nodes should be performed.
