Abstract:

Lymph node (LN) metastasis is among the important prognostic factors for survival in endometrial cancer (EC). This study aimed to evaluate the occurrence of lymphatic complications following lymphadenectomy in patients with EC.EC patients were retrospectively evaluated. Lower extremity lymphedema (LEL) and pelvic lymphocele (PL) were evaluated according to the International Society of Lymphology guidelines and the National Cancer Institute Common Terminology Criteria for Adverse Events, respectively.A total of 289 patients were enrolled. Surgery was performed via laparotomy and laparoscopy in 200 (69.2%) and 89 (30.8%) patients, respectively. LEL and PL occurred in 43 (14.9%) and 33 (11.4%) patients, respectively. In multivariate logistic regression analysis, circumflex iliac node (CIN) removal (odds ratio [OR]: 3.22; 95% CI: 1.43-7.98; P = 0.004) was an independent risk factor for LEL, while the surgical approach (OR: 4.46; 95% CI: 1.13-29.9; P = 0.004) was an independent risk factor for PL.CIN dissection was a significant risk factor for LEL, while laparotomy was an independent risk factor for PL compared to laparoscopy in EC patients. This suggests that laparoscopic surgery combined with sentinel lymph node navigation surgery will prevent lymphatic complications in low-risk EC patients.
