Abstract:
Objective Controversies exist as to the influences of the characteristics of lymph node metastasis ( LNM) on the prognosis of low-grade endometrial carcinoma ( LGEC) .The aim of this study was to investigate the risk factors of LNM and their im-pact on the prognosis of LGEC. Methods This study included 218 LGEC patients treated by retroperitoneal lymph node dissection. We analyzed the pathologic characteristics of LNM and its relationship with the survival rate of the patients. Results LNM was ob-served in 37 of the 218 patients (16.97%), including 20 cases of pelvic (54.05%), 6 cases of para-aortic (16.22%), and 11 ca-ses of both pelvic and para-aortic ( 29.73%) LNM.Independent risk factors of LNM included deep myometrial infiltration ( OR:5.21, 95%CI:2.77-9.81), cervical stromal involvement (OR:3.15, 95% CI:1.12-8.35), lymphovascular invasion (OR:1.15, 95%CI:1.02-1.30), and abnormally high serum CA125 (OR:3.46, 95%CI:1.56-7.67) (P<0.05).There were sig-nificant differences in the 3-year survival rate between the patients with LNM and those without LNM (83.8%vs 95.0%, P<0.05) as well as in the 3-year tumor-free survival rate (73.0% vs 90.1%, P<0.05). Conclusion Deep myometrial infiltration, cervical stromal involvement, lymphovascular invasion, and abnormally high serum CA125 are the risk factors of LNM in LGEC patients, and LNM affects the prognosis of the LGEC patients.
