Background The aim of this study was to determine the risk of para-aortic lymph node metastasis in surgically staged patients presenting with preoperative grade 1 endometrial cancer and to assess the impact of para-aortic lymphadenectomy. Materials and methods A total of 131 consecutive patients diagnosed with preoperative grade 1 endometrial cancer from 2004 to 2009 were analyzed. We included women with endometrial cancer that was thought preoperatively to be confined to the uterine corpus, and all patients had complete staging operation including total hysterectomy, bilateral salpingo-oophorectomy, peritoneal washings, pelvic lymphadenectomy, and para-aortic lymphadenectomy. Results Of 131 patients, 6 (4.6%) had positive para-aortic lymph nodes and only 2 (1.5%) had isolated para-aortic nodal metastasis with negative pelvic nodes. In comparison of preoperative and postoperative histology, 6.8% of patients were upgraded, with 5.3% grade 2 and 1.5% grade 3. Advanced stage disease was found in 12.9%. Deep myometrial invasion by MRI and CA 125 levels of ?1 U/ml were found to be independent preoperative risk factors for para-aortic lymph node metastasis. Conclusions Some patients with preoperative grade 1 endometrial cancer are found to have upgraded disease and para-aortic nodal metastasis. Para-aortic lymphadenectomy should be considered in patients presenting with preoperative grade 1 endometrial cancer, especially in the setting of preoperative CA 125 levels of >31?U/ml and deep myometrial invasion by MRI.
