Prophylactic Lymphatic Reconstruction Reduces Lymphedema Risk in Gynecologic Cancer

Lower extremity lymphedema remains a frequent consequence of inguinal lymphadenectomy, with prevalence rates reaching 30.96% (95% CI: 21.08 to 40.84) in patients treated for vulvar malignancies [1]. This chronic accumulation of protein-rich fluid leads to progressive limb enlargement, recurrent cellulitis, and a substantial decline in patient-reported quality of life [2, 3]. While delayed interventions such as vascularized lymph node transfer (the transplantation of healthy lymph nodes to an affected area to restore drainage) can reduce excess limb volume by approximately 25%, they rarely provide a definitive cure once the lymphatic architecture has collapsed [4, 5]. Consequently, clinical interest has shifted toward primary prevention through immediate lymphatic reconstruction at the time of initial cancer surgery [6]. A recent controlled study evaluates the efficacy of prophylactic lymph node-to-vein anastomosis (the surgical connection of lymph nodes to the venous system) in patients undergoing radical pelvic and inguinal clearance, reporting a reduction in lymphedema incidence from 49% to 8% at one year (p < 0.001) [7].
