Risk Factors for Re-Excision Following Breast-Conserving Surgery

Area of Science:

• Oncology
• Surgical Oncology
• Health Services Research

Background:

• Breast-conserving surgery (BCS) is a common treatment for breast cancer.
• Re-excision after BCS can lead to increased patient morbidity and healthcare costs.
• Identifying predictors of re-excision is essential for optimizing surgical outcomes.

Purpose of the Study:

• To identify novel factors predicting re-excision after BCS.
• To evaluate the feasibility of using breast density data for predictive modeling in BCS outcomes.

Main Methods:

• Retrospective analysis of 244 patients undergoing BCS from 2011-2012.
• Data sourced from cancer registry and electronic health records (EHRs).
• Univariate (chi-square) and logistic regression analyses were performed.

Main Results:

• Three key factors accurately predicted re-excision with 87% accuracy.
• Younger age (<60), wire localization, and timely surgery post-diagnosis were associated with lower re-excision rates.
• Breast density data feasibility for predictive modeling was assessed.

Conclusions:

• Specific patient and surgical factors can significantly reduce the likelihood of re-excision after BCS.
• Accurate and thorough documentation in EHRs is vital for nursing research and improving patient care.
• Nurses play a key role in facilitating timely surgical intervention for breast cancer patients.
