Comparing surgical and conservative treatments for chronic lymphedema after breast cancer

The LYMPH Trial - Comparing Microsurgical With Conservative Treatment of Chronic Breast Cancer Associated Lymphedema: Study Protocol of a Pragmatic Randomized International Multicentre Superiority Trial

Not applicable Interventional University Hospital, Basel, Switzerland · NCT05890677

This study is testing whether surgery can help improve the quality of life for people with chronic lymphedema after breast cancer compared to just using physical therapy.

What this trial studies

This study aims to evaluate whether lymphatic surgery improves quality of life for patients with chronic breast cancer-related lymphedema compared to conservative treatment alone. Participants will be randomly assigned to receive either surgical intervention or conservative complex physical decongestion therapy, which includes manual lymphatic drainage and compression. The effectiveness of these approaches will be assessed using a specific quality of life questionnaire 15 months after randomization. This multicentric randomized controlled trial seeks to provide evidence for the most effective treatment options for this condition.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a history of breast cancer and chronic lymphedema persisting for more than three months.

Not a fit: Patients with primary congenital lymphedema or those who have previously undergone surgical treatment for lymphedema on the affected side may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options and quality of life for patients suffering from chronic lymphedema after breast cancer.

How similar studies have performed: While conservative treatment is currently the standard, this study is novel as it is the first multicentric randomized controlled trial to compare surgical techniques directly against conservative treatment.
