Abstract

Objective: To identify predictors of extensive lymphatic dissemination and distant recurrences in node-positive endometrial cancer (EC). Methods: Clinicopathologic data were collected of patients who had fully staged EC with at least 1 positive lymph node. Permanent sections of metastatic lymph nodes were reviewed; metastases were characterized according to size (≤2 mm and >2 mm) and location in the lymph node (intra- vs extracapsular). Risk of occurrence of multiple pelvic and para-aortic lymph node dissemination was calculated by combining risk factors identified at multivariate analysis. Results: Of 96 patients, 85 had positive pelvic nodes, of whom 71 (83.5%) had high-volume metastases. In the presence of both macrometastasis in the pelvic basin (odds ratio [OR], 13.42; [95% CI, 2.44–73.83]) and uterine serosal involvement of the tumor at final pathologic evaluation (OR, 11.84 [95% CI, 1.22–115.11]), multiple pelvic node dissemination occurred in 91.7% of cases (vs 7.7% in the absence of both). Concomitant presence of pelvic macrometastasis, lymphovascular space invasion (LVSI), and extracapsular invasion led to 85.7% occurrence of para-aortic involvement (vs 11.1% if no factors present). LVSI was independently associated with nonvaginal recurrences (hazard ratio, 2.62 [95% CI, 1.33–5.16]). Conclusions: Presence of high-volume metastases in the pelvic lymph nodes is associated with concomitant presence of multiple positive pelvic nodes, as well as para-aortic node involvement. LVSI is associated with both para-aortic node involvement and occurrence of nonvaginal relapses. In this era of sentinel lymph node mapping, these factors may help predict the extent of lymphatic dissemination in EC.
