ABSTRACT
Preserving nipple-areola complex (NAC) in breast-conserving surgery and nipple-areola complex-sparing mastectomy (NSM) can achieve good tumor safety and breast aesthetics under the premise of appropriate case selection. However, there are still many doubts about the local anatomy of the nipple and NAC and how to preserve the NAC and reshape the shape of the nipple on the basis of selecting cases to achieve individualized treatment and complete tumor resection. In this paper, the NAC, internal nipple and posterior nipple anatomy are described in detail; Combined with the operation of NAC during NSM operation, the treatment of breast duct bundle inside the nipple and behind the nipple were introduced with author′s experience and pictures. The pathologic evaluation of preserving NAC, NAC conservation in breast cancer patients with nipple discharge and radiotherapy after NAC conservation were discussed. In fact, the current situation in our country is that too many patients may be suitable for immediate breast reconstruction or delayed breast reconstruction after NSM. It is very important to be familiar with the local anatomical characteristics of nipples and NAC for standardized breast conserving surgery and NSM. Therefore, more patients with breast cancer can safely retain NAC and breast, and breast reconstruction can be further accomplished on the basis of preserving NAC.
ABSTRACT
Objective:To investigate the efficacy and clinical value of two-stage implant-based breast reconstruction after total mastectomy for breast cancer patients.Methods:Thirty-two patients with breast cancer, who underwent nipple-sparing mastectomy or skin-sparing mastectomy, primary skin expander implantation, and permanent implant replacement after radiotherapy from January 2018 to December 2020 in the Breast Center, Beijing Tongren Hospital, Capital Medical University were analyzed retrospectively. Record the operation time of the patient, the interval between replacement surgery and radiotherapy, prosthesis volume, the difference between the volume of 0.9% sodium chloride solution in the dilator and the volume of the prosthesis, the retention time of the postoperative drainage tube, the satisfaction of the breast shape and the complications after the replacement.Results:The average operation time was (67.81±19.71) min; the average time interval between replacement surgery and radiotherapy was (9.88±2.00) months; the average volume of 0.9% sodium chloride solution in the dilator was (225.47±56.83) mL, and the average prosthesis volume was (259.06±70.88) mL, the average difference between the volume of the prosthesis and the volume of 0.9% sodium chloride solution in the dilator was (33.59±14.88) mL; the volume of the prosthesis is increased by an average of (13.65±5.19)% compared with the dilator; the average time of drainage tube retained after the operation was (9.03±1.40) d; satisfaction with breast shape after replacement: excellent in 23 cases (71.9%), general in 8 cases (25.0%), poor in 1 case (3.1%); postoperative complications: incision fat liquefaction 1 case of dehiscence (3.1%), 2 cases of seroma (6.3%), no serious complications such as external exposure and removal of the prosthesis.Conclusions:For patients with breast cancer, who need breast reconstruction after mastectomy, the two-stage implant-based breast reconstruction in which the replacement operation will be carried out more than 6 months after radiotherapy is safe. Moreover, achieve better symmetry and aesthetic effect by releasing the capsule, reconstructing the inframammary fold, and necessary plastic surgery of the contralateral breast.
ABSTRACT
Nipple-areola complex-sparing mastectomy (NSM) is a surgical procedure that allows the preservation of the skin and nipple-areola complex (NAC) in mastectomy. The use of NSM for breast cancer is still controversial. The appropriate standard for selecting patients with low risk of NAC involvement has not been well established. The clinicopathologicity characteristics of primary tumor (e.g., tumor-to-nipple distance, tumor location, tumor size, multicentricity, lymph node metastasis, lymphovascular invasion, grade, HER-2 status) have been reported to be associated with NAC involvement. Clinical evaluation of NAC, retroareolar tissue biopsy and evaluation of clinicopathologic characteristics of primary tumor are helpful to patient selection in current clinical practice of NSM. Further studies are still needed to establish uniform selection criteria for NSM in breast cancer patients.
ABSTRACT
With the development of surgical techniques, the use of nipple-areola complex (NAC)-sparing mastectomy (NSM) has been increasing. Except for oncologic safety, the aesthetic outcome of surgery is greatly concerned by clinicians and patients. So far, there has been no consensus on the incision of NSM. This article reviewed the literature so as to provide some evidence for the selection of NSM incision.
ABSTRACT
Nipple-areola complex (NAC)-sparing mastectomies (NSM) have gained acceptance in the ifeld of breast oncology. The superior aesthetic outcomes of NSM explain their increased use and rising popularity. Technical considerations and challenges of this procedure are centered on nipple ischemia and necrosis. Patient selection, reconstructive strategies and incision placement have lowered ischemic complication rates. An understanding of the NAC vascular anatomy is, therefore, clinically relevant beyond NSM. In this paper, the relevant clinical anatomy is described, mainly focusing on the anatomy of the NAC. This article also covers how to identify and classify the in vivo blood supply to the NAC using breast MRI exams which provide valuable information for assessing vascular anatomy of the NAC. This includes the arterial iflling phase, venous drainage phase and 3-dimensional reconstructed maximum intensity projection (MIP) images. Finally, the indocyanine green (ICG) and a specialized infrared camera-computer system provide surgeons with a practical tool to assess real-time breast skin and NAC perfusion. Intraoperative evaluation of skin perfusion allows surgeons to detect ischemia and modify the operative approach to reduce the risk of nipple ischemia and necrosis.
ABSTRACT
The technique of nipple-areola complex (NAC)-sparing mastectomy (NSM) facilitates the breast reconstruction due to preserving the skin and NAC of breast in the treatment of breast cancer. Key issues still remain controversial in NSM, in terms of the role of radiotherapy combined with NSM and sequence of radiotherapy and NSM, which arise from the consideration of the oncology safety. Some investigations addressed that post-NSM external beam irradiation and intra-operative radiotherapy (IORT) combined with NSM could reduce the local recurrence rate. Based on the appropriate patient selection and good quality of surgery, radiotherapy would be applied in different strategies of combination with NSM according to the risk of local recurrence of the cancer.
