Summary
Certain breast cancer patients need wider surgical margins during breast-conserving therapy (BCT) to avoid repeat surgeries. Identifying high-risk tumor and patient profiles helps surgeons optimize BCT outcomes.
Area of Science:
- Oncology
- Surgical Oncology
- Breast Cancer Research
Background:
- Breast-conserving therapy (BCT) is a common treatment for breast cancer.
- Identifying patients at higher risk for re-excision after BCT is crucial for improving outcomes.
- Predicting the need for wider surgical margins can reduce secondary procedures.
Purpose of the Study:
- To identify subgroups of women undergoing BCT at increased risk for secondary surgical procedures.
- To determine tumor and patient profiles that predict the need for larger surgical margins.
Main Methods:
- Study included 100 female patients with palpable, invasive breast carcinomas undergoing primary BCT.
- A subgroup of 25 patients with incomplete or questionable resections required re-excision.
Main Results:
- Multifocal disease, ductal carcinoma in situ, lymph node involvement, high-grade cancer (Grade 3), lympho-vascular invasion, and negative hormone receptor status were associated with incomplete tumor removal.
- These factors significantly increased the likelihood of requiring secondary surgery.
Conclusions:
- Clinical and pathological predictors can identify breast cancer patients needing larger safety margins during BCT.
- Optimizing margin size based on these predictors can minimize re-excision rates.
