What this trial studies

This Phase II clinical trial evaluates the feasibility and toxicity of using the PAPILLON +TM device for per-operative radiotherapy in patients with localized breast cancer who are 65 years or older. The study focuses on women with invasive ductal adenocarcinoma measuring 2 cm or less, and aims to determine the safety and effectiveness of this innovative treatment approach. Participants will be monitored for any adverse effects during the treatment process. The trial is multicentric and open for recruitment across specific locations in France.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 65 years or older with operable invasive ductal adenocarcinoma that is 2 cm or less in size.

Not a fit: Patients with metastatic disease, multifocal tumors, or those under 65 years of age will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a less invasive option for older women with localized breast cancer, potentially improving their quality of life and treatment outcomes.

How similar studies have performed: While this approach is innovative, similar studies using per-operative radiotherapy techniques have shown promise, suggesting potential for success.
