研究组 & 干预措施
Uni- or Bilateral Ductal Carcinoma in Situ (DCIS) or Invasive Breast Cancer
This retrospective, single-center study included 313 surgical procedures performed on 304 patients between January 2020 and December 2023. The patients underwent breast-conserving surgery (BCS) for unilateral or bilateral ductal carcinoma in situ (DCIS) or invasive breast cancer. All surgeries were performed by a single surgeon.
结局指标
主要结局

时间窗: 3 years
In this retrospective study, R1 resections were defined as cases requiring a follow-up surgery due to incomplete tumor removal.
次要结局
- Weight of main specimen(Day of excision)
- Duration of surgery(During surgery)
