简要总结
The investigators propose a randomized controlled superiority trial of standard breast-conserving surgery (BCS) versus BCS with cavity shave margins (CSM). The main objectives of this trial will be to evaluate prospectively the impact of routine standardized CSM on margin status following primary surgery for early stage breast cancer (Stage 0 - II), on post-operative patient satisfaction and cosmetic outcomes, and on general intraoperative time and operative costs. A parallel group format will be implemented to compare this modified surgical therapy - BCS with CSM - with BCS alone, which is the current standard of care.

结局指标
主要结局
Compare intraoperative NIR fluorescence from goggle system with pathologic tissue exam results
时间窗: Completion of surgery for all enrolled patients (approximately 60 months)
Patient perceptions of the surgery as measured by BREAST-Q questionnaire and novel 3-dimensional breast imaging
时间窗: 6-12 months post-surgery or post-radiation therapy, whichever is later)
* The BREAST-Q questionnaire consists of 13 sections. * The sections ask the patient questions about how they feel about how their breast area looks, how they feel emotionally, any physical side effects, and sexual side effects. * Some of the sections ask the patients to answer a question on a scale of None of the Time (equals=1) to All of the Time (equals=5) * Some of the sections ask the patients to answer a question on a scale of Very Dissatisfied (equals=1) to Very Satisfied (equals=4)
Proportion of patients with positive margins on pathological specimen analysis
时间窗: Completion of surgery for all enrolled patients (approximately 60 months)
次要结局
- Tumor characteristics associated with cancer biomarkers(Completion of surgery for all enrolled patients (approximately 60 months))
- Relationship between CSM and volume of tissue excised in association iwth post-operative aesthetic outcomes(6-12 months post-surgery or post-radiation therapy, whichever is later))
- Cost-effectiveness of routine CSM in BCS as measured by operative time, specimen processing, and resource usage(Completion of surgery for all enrolled patients (approximately 60 months))
- Disease status associated with cancer biomarkers(Completion of surgery for all enrolled patients (approximately 60 months))
