Evaluating the Impact of Immediate Lymphatic Reconstruction for the Surgical Prevention of Lymphedema.

BACKGROUND

Breast cancer-related lymphedema affects one in five patients. Its risk is increased by axillary lymph node dissection and regional lymph node radiotherapy. The purpose of this study was to evaluate the impact of immediate lymphatic reconstruction or the lymphatic microsurgical preventative healing approach on postoperative lymphedema incidence.

METHODS

The authors performed a retrospective review of all patients referred for immediate lymphatic reconstruction at the authors' institution from September of 2016 through February of 2019. Patients with preoperative measurements and a minimum of 6 months' follow-up data were identified. Medical records were reviewed for demographics, cancer treatment data, intraoperative management, and lymphedema incidence.

RESULTS

A total of 97 women with unilateral node-positive breast cancer underwent axillary nodal surgery and attempt at immediate lymphatic reconstruction over the study period. Thirty-two patients underwent successful immediate lymphatic reconstruction with a mean patient age of 54 years and body mass index of 28 ± 6 kg/m2. The median number of lymph nodes removed was 14 and the median follow-up time was 11.4 months (range, 6.2 to 26.9 months). Eighty-eight percent of patients underwent adjuvant radiotherapy of which 93 percent received regional lymph node radiotherapy. Mean L-Dex change was 2.9 units and mean change in volumetry by circumferential measurements and perometry was -1.7 percent and 1.3 percent, respectively. At the end of the study period, we found an overall 3.1 percent rate of lymphedema.

CONCLUSION

Using multiple measurement modalities and strict follow-up guidelines, the authors' findings support that immediate lymphatic reconstruction at the time of axillary surgery is a promising, safe approach for lymphedema prevention in a high-risk patient population.
