Large-area Low-level Laser Therapy for Breast Cancer-related Lymphedema: a Randomized, Placebo-controlled Study

Not applicable Interventional National Taiwan University Hospital · NCT05725265

This study is testing whether a larger area of low-level laser therapy can help women with breast cancer-related swelling in their arms feel better compared to standard treatment.

What this trial studies

This study compares the effectiveness of large-area versus conventional low-level laser therapy (LLLT) in treating breast cancer-related lymphedema (BCRL) following mastectomy. It aims to measure changes in the severity of lymphedema through circumference and skin thickness assessments using ultrasound, while also evaluating clinical symptoms such as pain, shoulder mobility, and hand function. The study targets female patients with unilateral BCRL and will monitor their progress over time to determine the best therapeutic approach.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 20 and older with unilateral breast cancer who have undergone lumpectomy or mastectomy and lymph node dissection, and who exhibit stage I or II lymphedema.

Not a fit: Patients with metastatic cancer, pregnancy, or other conditions that could complicate lymphedema treatment will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly alleviate symptoms and improve the quality of life for patients suffering from breast cancer-related lymphedema.

How similar studies have performed: Previous studies have shown promising results with low-level laser therapy for lymphedema, suggesting this approach may be effective.
