Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 with histologically proven invasive breast cancer, no more than 5 cm in size, and 1-2 positive sentinel lymph nodes.

Probably not a fit

Patients who have undergone axillary dissection, have distant metastases, or have severe comorbidities may not benefit from this study.

What this trial studies

This observational study focuses on patients with invasive breast cancer who have 1-2 sentinel lymph nodes with macrometastases and are scheduled for conservative surgery. It aims to assess the risk of developing arm lymphedema following hypofractionated intensity-modulated radiotherapy (IMRT) to the breast and axillary lymph nodes. By avoiding axillary dissection and using advanced radiotherapy techniques, the study seeks to improve patient outcomes and minimize side effects. Participants will be monitored for lymphedema development post-treatment.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of arm lymphedema in breast cancer patients, improving their quality of life.

How similar studies have gone: Previous studies have shown promising results with similar hypofractionated radiotherapy approaches, indicating potential for success.
