SHORT DURATION OF UPPER EXTREMITY LYMPHEDEMA CORRELATES WITH A FAVORABLE CYTOKINE RESPONSE AFTER LYMPH NODE TRANSFER SURGERY

---

Abstract

Vascularized lymph node transfer surgery (VLNT) can provide benefit to lymphedema patients. Cytokines may play a role in the development of lymphedema and in the regeneration of lymphatic vessels after VLNT. Our primary aim was to investigate whether the VLNT patients have a specific cytokine profile. Our secondary aim was to see whether the preoperative lymphedema or severity affects the postoperative cytokine response. Wound exudate was gathered from 18 patients undergoing VLNT on the first and sixth postoperative day (POD). The concentrations of IL-10, TNF-α, TGF-β1 and VEGF-C were analyzed using enzyme-linked immune-sorbent assays. A general score was generated to assess the benefit of the surgery. The changes in cytokine concentrations (1st POD-6th POD) were correlated with the pre- and postoperative lymphedema related factors. A shorter duration of lymphedema preoperatively correlated with an increase in the concentration of IL-10 and TNF-β during the first six PODs (IL-10: r=0.495, p=0.051; TNF-α: r=0.737, p=0.006) and a decrease in the concentration of TGF-s1 (r= -0.613, p=0.020). The increase of the concentration of TNF-α during the first six PODs also correlated with a greater total general score (r=0.775, p=0.005) and hence indicated a better response to the surgery. The patients with a shorter duration of lymphedema preoperatively had a more favorable cytokine response during the first six PODs after VLNT.
