The LYMPH Trial - Microsurgical Versus Conservative Treatment of Chronic Breast Cancer Associated Lymphedema

PROCEDURE

Surgical Intervention

LVA (Lymphovenous Anastomosis) and VLNT (Vascularised Lymph Node Transfer) are two advanced microsurgical techniques that are increasingly implemented in clinical practice in specialized centers and that are already carried out after health insurance application according to local standard of care. They have been studied in their respective mode of action as well as in their effectiveness in treating chronic BCRL (Breast Cancer-Related Lymphedema) in a multitude of mostly observational and single center studies with highly encouraging results. Patients in the interventional arm A will receive surgery with one of the two approaches or a combination of both, in a one or two-stage method, at the discretion of the treating surgeon. Depending on local standards one or both of the above might be combined with liposuction to the affected arm in a one or two-stage approach as well.

PROCEDURE

Conservative Complex Physical Decongestion Therapy

Patients randomized to the control arm will receive CDT (Conservative Complex Physical Decongestion Therapy), which currently is considered as the best available standard of care. For this, patients will be referred to one of the dedicated LE (physical/skin) therapy clinics, if not already treated by one, according to their place of residence for continuation of standard conservative therapy. Recommendations to the procedures and treatment frequency of the conservative therapy will be made, but CDT will be done at the discretion of the treating physiotherapist.

Change in Quality of Life Questionnaire (Lymph-ICF-UL)

Time frame: two time assessment at baseline and 15 month after randomization

The LYMPH-ICF-UL-Questionnaire (Lymphedema Functioning Disability and health questionnaire for upper limb lymphedema) is a widely used, rigorously developed, and validated patient-reported outcome (PRO) instrument for chronic breast cancer-related lymphedema. It assesses the impairments in function, activity limitations and participation restrictions of patients with upper limb lymphedema (LE). Consisting of 29 items (questions) across five different domains, each item is scored on a VAS (visual analog scale) ranging from 0 to 10. The total score on the LYMPH-ICF is equal to the sum of the item scores divided by the total number of answered items. A higher score on the Lymph-ICF indicates a greater impact on the functioning in daily life related to upper limb LE. This questionnaire helps determine if lymphatic surgery improves quality of life and patient satisfaction compared to conservative therapy.

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
