Postoperative Lower Extremity Edema in Patients with Primary Endometrial Cancer.
Annals of Surgical Oncology 2016 January
PURPOSE: The goal of this study was to investigate clinical manifestations of lower extremity edema (LEE) after lymph node dissection in patients with primary endometrial cancer.
METHODS: Women with primary endometrial cancer who underwent staging surgery between November 2001 and March 2011 were included in the study. Medical records and/or responses to the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) were used for LEE evaluation.
RESULTS: All 154 patients underwent pelvic lymph node dissection, and 126 patients (81.8 %) underwent paraaortic LN dissection. The median age of the patients was 52 years, the majority had stage I cancer (78.6 %), and most had endometrioid histology (90.9 %). The most frequent GCLQ responses were "experienced swelling" (35.7 %), "experienced numbness" (30.5 %), "experienced heaviness" (29.9 %), and "experienced aching" (29.9 %). Sixty-four patients (41.6 %) had previous (9/64, 14.1 %) and/or current (55/64, 85.9 %) patient-reported LEE. Most patients developed LEE within 12 months after surgery (39/56, 69.6 %), and LEE lasted for more than 12 months in most patients (45/56, 80.4 %). Three patients reported recurrent LEE after recovery. Multivariate logistic regression identified the number of dissected pelvic lymph node (≥21) as a risk factor for LEE [odds ratio (OR) 3.28; 95 % confidence interval (CI) 1.058-10.136] and postoperative radiotherapy (OR 3.81, 95 % CI 1.67-8.69).
CONCLUSIONS: LEE developed in more than one-third of patients with endometrial cancer after surgery, and LEE lasted for more than 12 months in most patients. A high number of dissected pelvic lymph nodes and postoperative radiotherapy is associated with LEE.
