Abstract
BACKGROUND: The purpose is to determine the rate of lymph node metastases in women with endometrioid adenocarcinoma of the endometrium (EAE) undergoing systematic lymphadenectomy. METHODS: Patients (349) underwent a complete pelvic and para-aortic lymphadenectomy from caudal to the median circumflex to the level of the renal vessels. RESULTS: Grade 1 tumors accounted for 32.7% of the tumors and 31.0% of the positive nodes, grade 2 accounted for 47.3% of the tumors (37.9% of positive nodes), and grade 3 accounted for 20.1% of the tumors and 31.0% of the positive nodes (P>0.05). Positive nodes were found in 15.8% of grade 1 tumors, 13.3% of grade 2 tumors and 25.7% of grade 3 tumors (P>0.05). Isolated para-aortic involvement without pelvic nodal involvement occurred in 29% of patients with positive nodes. CONCLUSIONS: When complete lymphadenectomies are performed in EAE, positive lymph nodes (including isolated para-aortic lymph nodes) are common in all grades.
