The N-LVA Study: RCT Comparing LVA vs. Sham Surgery in Cancer-related

Status Recruiting

Clinical Trial Summary

The goal of this randomized controlled trial is to compare the effectiveness and cost-effectiveness of lymphaticovenous anastomosis (LVA) with sham surgery for patients suffering from unilateral cancer-related lymphedema in either the upper or lower extremity. It aims to answer whether LVA is more effective than sham surgery in terms of improvement in Lymph-ICF score. A total of 110 participants will be allocated randomly into two groups at a 1:1 ratio. The first group will receive lymphaticovenous anastomosis (LVA), while the second group will undergo sham surgery.

Clinical Trial Description

One of the most debilitating side effects of cancer treatment is cancer-related lymphedema (CRL), with an overall incidence of 15.5%. To date, there is no definite cure for lymphedema. Conservative therapy, namely complex decongestive therapy is the golden standard for the treatment. Lymphaticovenous anastomosis (LVA) might be a promising treatment modality for patients with CRL, but available studies are small and the quality is lacking. No large-scale prospective or randomized studies have been published on the efficacy of LVA. The main objective of this randomized controlled trial is to assess whether LVA is more effective than sham surgery in terms of improvement in Lymph-ICF score, volume reduction, reduction of complex decongestive therapy, and cost-effectiveness. The study will take place in three centers in the Netherlands: Maastricht University Medical Center, Radboud University Medical Center, and Erasmus University Medical Center. The patients will be randomly distributed into two groups: the LVA group or the Sham group. Both procedures are performed under local anesthesia. Patients in both groups are subject to minor surgical complications (wound infection, bleeding, wound dehiscence). Special care will be taken to prevent damage to lymphatic vessels in the Sham group, to allow a future LVA operation once the study ends. The follow-up moments will be at 3, 6, 12, 18, and 24 months. Additionally, a subset of patients will partake in an annual extended follow-up, ongoing until the start of the analysis. Each follow-up moment will last 45 minutes in total. The patient also receives two digital questionnaires at each follow-up moment. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
