Is this trial a fit for you?

Likely a 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.

Probably 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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

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 gone: 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.
