Correlation between clinical and histopathologic risk factors and lymph node metastases in early endometrial cancer (a multivariate analysis of 183 cases).
This study includes 183 patients with clinical stage I endometrial cancer subjected to peritoneal cytology, total abdominal hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic and para-aortic lymphadenectomy and omental biopsy during a 12-year period in a single institution. The factors analyzed were age, menopausal state, cell type, grade, mitotic activity, myometrial invasion, lymphovascular space invasion, cervical involvement, microscopic vaginal metastases, adnexal metastases, peritoneal cytology, presence of concomitant endometrial hyperplasia and lymph node status. The overall incidences of pelvic and para-aortic lymph node metastases were found to be 15.3% (28/183) and 9.3% (17/183), respectively. In five of 17 patients (29.4%) with para-aortic nodal metastases, pelvic nodes were free of tumor. The most significant prognostic factors for positive pelvic and/or para-aortic nodes were found to be the depth of myometrial invasion, grade of tumor and age.
