No fertility needs, surgery is still needed for radical cure For patients who do not consider fertility or do not need to preserve fertility, do not hesitate to have surgery, as surgery is the main way to radically cure endometrial cancer. Removal of uterus, ovaries and lymph nodes is the basic scope Many patients are concerned about how much they need to be cut off in surgery. The scope of surgery for endometrial cancer is determined according to the stage of cancer and preoperative imaging results. The basic principle is “removal of visible lesions”, which usually requires removal of the entire uterus + both adnexa (ovaries and fallopian tubes) + pelvic and para-aortic lymph node dissection. Many patients do not understand why lymph node dissection is necessary, because the first stop of cancer cells metastasis is the adjacent lymph nodes, if they have metastasized to the lymph nodes without dissection, only the cancerous tissue will recur soon. Lymph nodes are the sentinels of the body, and they will be enlarged if there are viral or bacterial infections or cancer cell invasion. Although we have done imaging examinations such as ultrasound or CT or MRI before surgery, the lymph nodes may not be obviously enlarged and we cannot be 100% sure whether they have metastasis or not, so lymph node dissection is also done intraoperatively to clarify the staging and diagnosis. Of course, with the advancement of medicine, perhaps in the future, some patients may be able to accurately determine the status of lymph nodes before surgery and no longer need lymph node dissection, we are waiting to see. If the lesion is limited to the body of the uterus (endometrial cancer stage I), after hysterectomy + bilateral adnexal (ovarian and bilateral adnexal) resection + pelvic and para-abdominal aortic lymph node dissection, the 5-year survival rate of patients can reach more than 90%. If the lesion spreads to the cervix (stage II), pelvis or other organs in the abdominal cavity (stage III), the operation is further extended. For post-operative adjuvant treatment, including radiotherapy and chemotherapy, all of them are based on the stage of the lesion and all aspects of the patient’s body, and the treatment plan will be evaluated by the doctor, which will not be discussed here. The excised tissues are sent for pathological examination to determine whether the excision is clean. Many patients may also worry about how to determine whether their surgery is successful and whether the lesions are clean. After surgery, the surgeon will do pathological diagnosis on the excised tissues. One is to determine whether there is metastasis in the lymph nodes, and the other is to see whether the edges of the excised tissue are clean (i.e. normal tissue structure). If the result of the examination is that the edges are all normal, then it can be concluded that the operation is clean.
