Two hundred and eight patients with a clinical stage I endometrial carcinoma were studied (164 fulfilled the inclusion criteria). High risk was defined as nonendometrioid, or endometrioid tumors grade 3 (G3), or G2 with any or G1 with deep (>1/2) myometrial infiltration. The low-risk group consisted of the remaining patients. Surgical staging in the high-risk group included pelvic lymphadenectomy with para-aortic lymphadenectomy in selected cases. Twelve percent of the high-risk patients had nodal metastasis. Patients with low-risk (group A, n = 85) and high-risk disease confined to the uterus (group B, n = 57) did not receive adjuvant radiotherapy. Patients with nodal metastases (group C, n = 10) received postoperative irradiation. The total recurrence rate of the entire population was 12.5%, and the actuarial overall survival, disease-specific survival, and disease-free survival were 90%, 94%, and 88%, respectively. All patients with only vaginal relapse (n = 9) were cured locally with salvage radiotherapy until the date of analysis. The pelvic relapse rate was low as only one patient of group B recurred in the pelvis. In conclusion, lymphadenectomy remains indicated to better select patients at high risk of pelvic recurrence that may benefit from postoperative radiotherapy.
