Patient: Description of condition (onset, main symptoms, hospital visited, etc.): The patient is a female, 55 years old, previously in good health, and at the end of April this year, she was examined by a doctor for endometriosis (precancerous lesion) and underwent a total hysterectomy after a review to confirm the disease. This time, the examination showed that there was a slight heart disease and diabetes (which could be controlled). Total hysterectomy was performed after review and confirmation of the disease. Diagnostic findings: high-grade intraepithelial neoplasia of the endometrium, small focal carcinoma, chronic cervicitis, phosphorylation of the glandular glands, chronic tubal inflammation with adnexa, and white bodies visible in the ovaries. After excision, the specimen was examined: the uterus was grayish red, the uterus was 10*9*5cm, the cervix was 4.5*3cm, the endometrial thickness of the uterus was 0.1cm, and there were no obvious masses on the cut surface. Is it possible to determine from the above that chemotherapy is necessary? Hospital: From the above situation, chemotherapy should not be necessary. My judgment is based on the following: 1. High-level endometrial intraepithelial neoplasia and small focal carcinoma: I deduce that the lesion should be highly differentiated and confined to the endometrial layer. I can borrow pathological slides for consultation in our hospital. 2, chronic cervicitis with phosphorylation of glands: the cervix is not invaded and phosphorylation of glands is inflammation 3, no report of lymph node and ascites cytology: incomplete staging According to the above analysis, it is endometrial cancer stage Ia grade I. NCCN (international authoritative cancer treatment guidelines) suggests that incomplete staging of endometrial cancer stage Ia G1 can be observed.
