Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 with infiltrating breast carcinoma, specifically triple negative or HER2-positive, who have undergone at least 12 weeks of neoadjuvant chemotherapy.

Probably not a fit

Patients with bilateral or multicentric tumors, or those with a history of previous breast cancer, may not benefit from this study.

What this trial studies

This study evaluates the safety and efficacy of using radiotherapy alone for patients with breast cancer who have achieved a complete pathological response after neoadjuvant chemotherapy. It involves histological confirmation of this response through vacuum-assisted biopsy or excision guided by ultrasound. The primary goal is to demonstrate that this non-surgical approach is not inferior to traditional surgical methods. By focusing on patients with specific types of breast cancer, the study aims to explore innovative treatment options that could potentially reduce the need for surgery.

Why it matters

Potential benefit: If successful, this approach could provide a less invasive treatment option for breast cancer patients, potentially improving their quality of life.

How similar studies have gone: While this approach is innovative, similar studies exploring non-surgical options for breast cancer have shown promise, indicating potential for success.
