Abstract

PURPOSE: The PREVENT randomized trial assessed progression to chronic breast cancer-related lymphedema (cBCRL) after intervention triggered by bioimpedance spectroscopy (BIS) or tape measurement (TM). This secondary analysis identifies cBCRL risk factors on the basis of axillary treatment.

METHODS: Between June 2014 and September 2018, 881 patients received sentinel node biopsy (SNB; n = 651), SNB + regional node irradiation (RNI; n = 58), axillary lymph node dissection (ALND; n = 85), or ALND + RNI (n = 87). The primary outcome was the 3-year cBCRL rate requiring complex decongestive physiotherapy (CDP).

RESULTS: After a median follow-up of 32.8 months (IQR, 21-34.3), 69 of 881 patients (7.8%) developed cBCRL. For TM, 43 of 438 (9.8%) developed cBCRL versus 26 of 443 (5.9%) for BIS (

CONCLUSION: The extent of axillary treatment is a significant risk factor for cBCRL. Increasing BMI, rurality, SCF radiation, and taxane chemotherapy also increase risk. These results have implications for a proposed risk-based lymphedema screening, early intervention, and treatment program.
