DIEP flap breast reconstruction combined with vascularized lymph node transfer for patients with breast cancer-related lymphedema.

[INTRODUCTION] Lymphedema is a condition which heavily impacts patients QoL. For patients who desire autologous breast reconstruction, lymph nodes can be included in the Deep Inferior Epigastric Artery (DIEP) flap combining vascularized lymph node transfer and autologous breast reconstruction.

[MATERIAL AND METHODS] Patients who received autologous breast reconstruction with a DIEP flap in combination with vascularized lymph nodes were included in this study. Volume measurements pre and post-surgery were analyzed and surveys including two versions of the ULL-27 questionnaire to measure QoL before and after surgery were send.

[RESULTS] In total, 45 out of 64 patients returned the questionnaires. The average follow up was 51 months. The total ULL-27 score increased with 12.6 points on average (p = 0.00). The subdomain scores (physical, psychological and social) also significantly increased (p = 0.00). In addition 69% of patients were able to decrease physiotherapy, 63% of patients were able to decrease compression garment usage and the incidence of skin infections decreased in 6 patients out of 7 patients who had recurrent skin infections prior to surgery. The volume difference between the affected and the healthy arm did not significantly change (407 ml-406 ml, p = 0.988).

[CONCLUSIONS] Vascularized lymph node transfer in combination with DIEP flap breast reconstruction can cause a significant improvement on lymphedema related QoL, even when a volume difference decrease is absent. It can also decrease compression garment usage and reduce the need for physiotherapy. Future prospective studies should evaluate these findings and identify patients that benefit most from such procedures.
