What is this trial about?

The goal of this clinical study is to explore whether preoperative application of 3D printing technology to evaluate breast blood supply can improve the occurrence of ischemic complications in the flap and nipple areola complex after surgery.

What are the participation requirements?

Yes

Inclusion Criteria

- Pathologically confirmed diagnosis of breast cancer

- Age: 18 to 70 years old

- No infiltration of the nipple-areola complex and negative histopathology of the nipple basal margins;

- Patients who meet the indications for breast conserving surgery require total mastectomy and reconstruction;

No

Exclusion Criteria

- Inability to tolerate surgery or subjective desire not to undergo nipple-sparing mastectomy;

- Patients with clinical or imaging evidence of preoperative involvement of the nipple/areolar region, including Paget's disease, nipple spillage, inflammatory breast cancer, and/or imaging findings suggesting malignant involvement of the nipple or subareolar tissues, according to the 2023 NCCN guideline recommendations, where retaining the NAC fails to yield negative margins;
