BACKGROUND: Lymphedema is a chronic, debilitating disease that often requires life-long management. Predicting clinical manifestations and prognosis is crucial in clinical practice because the treatment of lymphedema should be individualized for best clinical outcome. The aim of this study is to explore the location and severity of lymphedema secondary to inguinal and/or iliac lymph node dissection (LND) in patients with melanoma.
METHODS: Patients with melanoma who received LND at a single tertiary medical center between 1 January 2010 and 31 September 2022 were retrospectively reviewed. Patient who received inguinal LND only were designate as the inguinal group while those who received both ilioinguinal LND were included in the ilioinguinal group. Volumetric measurement was used to objectify the severity and location of lymphedema. Clinical data was acquired for 12-15 months of follow-up.
RESULTS: Among 81 patients, 43 (53%) had developed lymphedema in the lower extremities at an average of 33 days after the surgery. Initially, patients manifested with medial thigh lymphedema in the inguinal group while patients were presented with whole leg lymphedema in the ilioinguinal group. Lower leg volume of the ilioinguinal group was significantly higher than the inguinal group. After more than 12 months of lymphedema treatment, upper leg volume was higher in the ilioinguinal group than the inguinal group (12.7% vs 5.4%, p < 0.05).
CONCLUSION: Lymphedema developed in early post-op period. The ilioinguinal group presented with a larger volume of lymphedema in the distal area of the legs. Even after sufficient treatment, predominant lymphedema remained in the proximal leg for the ilioinguinal group. Patients with both inguinal and iliac LND were associated with more severe lymphedema. Based on the dissection sites, the clinical manifestations and prognosis of leg lymphedema can vary widely. Thus, clinicians should consider the dissection site when approaching melanoma patients with lymphedema.
