Standard treatment options:
A total abdominal hysterectomy and bilateral salpingo-oophorectomy should be done if the tumor:
Selected pelvic lymph nodes may be removed. If they are negative, no postoperative treatment is indicated. Postoperative treatment with a vaginal cylinder is advocated by some clinicians.
For all other cases and cell types, a periaortic and selective pelvic node sampling should be combined with the total abdominal hysterectomy and bilateral salpingo-oophorectomy, if there are no medical or technical contraindications. One study found that node dissection per se did not significantly add to the overall morbidity from hysterectomy. While the radiation therapy will reduce the incidence of local and regional recurrence, improved survival has not been proven and toxic effects are worse.[3,4,5,6] Results of two randomized trials on the use of adjuvant radiation therapy in patients with stage I disease did not show improved survival but did show reduced locoregional recurrence (3%–4% vs. 12%–14% after 5–6 years' median follow-up, P < .001) with an increase in side effects.[6,7,8][Level of evidence: 1iiDii]
If the pelvic nodes are positive and the periaortic nodes are negative, total pelvic radiation therapy, including the common iliac nodes, should be given. The incidence of bowel complications is approximately 4%, and it can be even higher if the radiation therapy is given after pelvic lymphadenectomy. If the surgery is done using a retroperitoneal approach, the toxic effects are lessened. If the periaortic nodes are positive, the patient is a candidate for clinical trials that could include radiation therapy and/or chemotherapy. Patients who have medical contraindications to surgery should be treated with radiation therapy alone, but inferior cure rates below those attained with surgery may occur.[1,10,11]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage I endometrial carcinoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
