Abstract
Purpose: Microsurgical reconstruction, including vascularized lymph node transfer (VLNT) and lymphaticovenous anastomosis (LVA), have emerged as promising treatment options for chronic breast cancer-related lymphedema (BCRL). Despite their clinical relevance, the precise timelines for patient improvement following these interventions remain rather unexplored. Therefore, the goal of this study was to compare the long-term outcomes and improvement patterns over time of VLNT versus LVA to lay open potential differences and aid in personalized counseling of future patients.
Methods: A prospectively maintained, encrypted database was analyzed for patients with chronic BCRL treated with either VLNT or LVA with a minimum follow-up of one year. Patient-specific variables, such as body weight and circumferential arm measurements at distinct locations on both arms were documented preoperatively and on regular postoperative outpatient follow-ups.
Results: This study comprised 112 patients, of which 107 patients fully completed the one-year follow-up period. Both VLNT and LVA achieved significant arm size reductions. LVA showed an early peak in effectiveness within the first three months, followed by a subsequent decrease and eventual stabilization. Contrarily, VLNT exhibited a distinct pattern with two significant peaks at three and eighteen months.
Conclusions: VLNT and LVA are both effective in long-term lymphedema management, yet they demonstrate marked differences in the timing of improvement. VLNT shows a delayed but more durable response, in contrast to the greater but shorter-lasting surge in effectiveness achieved by LVA. Interestingly, VLNT demonstrates an earlier onset of therapeutic impact than previously understood.
期刊介绍:
Breast Cancer Research and Treatment provides the surgeon, radiotherapist, medical oncologist, endocrinologist, epidemiologist, immunologist or cell biologist investigating problems in breast cancer a single forum for communication. The journal creates a "market place" for breast cancer topics which cuts across all the usual lines of disciplines, providing a site for presenting pertinent investigations, and for discussing critical questions relevant to the entire field. It seeks to develop a new focus and new perspectives for all those concerned with breast cancer.
