Conditions

BRCA1/2 Mutation, Breast-conserving Surgery

Brief summary

The investigators matched BCS and mastectomy group using propensity scores and analyzed the recurrence and survival among the evenly matched patients in breast cancer patients with BRCA 1/2 mutations.

Detailed description

The purpose of study is to assess the oncologic safety of BCS in patients carrying BRCA1/2 mutations by comparing long-term outcomes with mastectomy. The investigators matched BCS and mastectomy group using propensity scores and analyzed the recurrence and survival among the evenly matched patients. By providing insights into the feasibility of BCS for patients with BRCA1/2 mutations, the investigators aim to present evidence to aid in surgical decision-making for the care of these patients.

Interventions

PROCEDUREBreast-conserving surgery

Breast-conserving surgery, also known as breast-conserving therapy or lumpectomy, is a surgical procedure used to treat breast cancer while preserving as much of the breast tissue as possible. During this procedure, the surgeon removes the cancerous tumor along with a surrounding margin of normal tissue. The goal is to remove the cancerous cells while maintaining the appearance and function of the breast as much as possible.
