Impact of systematic shaving on tumor margins in breast cancer surgery

Reduction of Affected Margins in Conservative Surgery for Breast Cancer: Impact of Systematic Shaving in the Operating Room

Not applicable Interventional Hospital Universitari de Bellvitge · NCT05782686

This study tests if a new shaving technique during breast cancer surgery can help reduce the chances of leftover cancer cells and the need for more surgeries.

What this trial studies

This clinical trial aims to evaluate the effectiveness of a systematic shaving technique during breast-conserving surgery to reduce positive margins in patients with breast cancer. Patients are randomized into two groups: one receiving the shaving intervention and the other undergoing standard surgery. The primary goal is to compare the outcomes in terms of definitive pathology and the need for additional interventions due to margin issues. This approach seeks to improve surgical outcomes and minimize the likelihood of further surgeries.

Who should consider this trial

Good fit: Ideal candidates are women undergoing breast-conserving surgery for breast cancer with a confirmed diagnosis of carcinoma in situ or infiltrating.

Not a fit: Patients who may not benefit include men, those with a history of breast cancer, or those requiring mastectomy.

Why it matters

Potential benefit: If successful, this technique could lead to fewer positive margins and reduce the need for additional surgeries in breast cancer patients.

How similar studies have performed: While the specific approach of systematic shaving is novel, similar studies focusing on margin management in breast cancer surgery have shown promising results.
