Lessons Learned from Three Different Acellular Dermal Matrices in Direct-to-Implant Breast Reconstruction

The aim of the study was to show significant differences regarding postoperative complications and outcomes using three different Acellular Dermal Matrices (ADM), namely Epiflex®, Strattice® and Braxon®, in immediate implant-based subpectoral breast reconstruction cases. Background: The use of Acellular Dermal Matrices for implant-based breast reconstruction cases continues to evolve. There is a wide variety of products which differ significantly in their biological features. It remains unclear if and how these differences manifest in clinical practice. Methods: 82 cases of primary breast reconstruction in the Department of Plastic and Aesthetic Surgery of HELIOS Clinics Schwerin, Germany between 2010 and 2018 were analyzed. 25 patients received Strattice® acellular dermal matrix (SADM), 22 cases Epiflex® acellular dermal matrix (EADM) and the remaining 35 cases Braxon® acellular dermal matrix (BADM). The mean follow-up was 1.8 years. Cases were analyzed regarding minor or major complications and rate of capsular contracture grade III or IV (Baker Classification). Results: The overall complication rate was 34.1% for all groups (SADM = 40%, EADM = 50%, BADM = 20%, p-value = 0.051). Of all cases, 6 patients underwent implant exchange or secondary autologous reconstruction due to capsular contracture (7.3%). The mean time between revision due to capsular contracture and reconstruction was 35.8 ± 14.4 months. 50% of patients, who developed capsular contracture, received postoperative radiation. Mean hospitalization time was 8.2 ± 3 days (SADM = 8 ± 3.2 days, EADM = 10 ± 2.8 days, BADM = 6 ± 1.3 days). There were no significant differences between all three groups for demographics, overall complication rate or capsular contracture. However, patients receiving Braxon® matrix showed significantly fewer minor complications (p-value = 0.01). Moreover, patients receiving Braxon® ADM showed a significantly lower time of hospitalization (p < 0.001). Conclusion: No significant differences regarding the overall complication rate were found between the three groups. Different biological features of ADM showed a weak influence on overall results. However, patients receiving Braxon® ADM showed significantly lower minor complication rates and hospitalization time. In addition, these matrices showed a trend towards lower capsular contracture rates. The low rate of capsular contracture hints at possible advantages of ADM-use in direct-to-implant cases.

A prospective study comparing endoscopic subcutaneous mastectomy plus immediate reconstruction with implants and breast conserving surgery for breast cancer

Background Breast conserving surgery （BCS） has been the standard surgical procedure for the treatment of early breast cancer. Endoscopic subcutaneous mastectomy （ESM） plus immediate reconstruction with implants is an emerging procedure. The objective of this prospective study was to evaluate the clinical outcomes of these two surgical procedures in our clinical setting. Methods From March 2004 to October 2007, 43 patients with breast cancer underwent ESM plus axillary lymph node dissection and immediate reconstruction with implants, while 54 patients underwent BCS. The clinical and pathological characteristics, surgical safety, and therapeutic effects were compared between the two groups. Results There were no significant differences in the age, clinical stage, histopathologic type of tumor, operative blood loss, postoperative drainage time, and postoperative complications between the two groups （P 〉0.05）. The postoperative complications were partial necrosis of the nipple and superficial skin flap in the ESM patients, and hydrops in the axilla and residual cavity in the BCS patients. There was no significant difference in the rate of satisfactory postoperative cosmetic outcomes between the ESM （88.4%, 38/43） and BCS （92.6%, 50/54） patients （P 〉0.05）. During follow-up of 6 months to 4 years, all patients treated with ESM were disease-free, but 3 patients who underwent BCS had metastasis or recurrence -- one of these patients died of multiple organ metastasis. Conclusions After considering the wide indications for use, high surgical safety, and favorable cosmetic outcomes, we conclude that ESM plus axillary lymph node dissection and immediate reconstruction with implants -- the new surgery of choice for breast cancer -- warrants serious consideration as the prospective next standard surgical procedure.

Immediate nipple-areola-sparing mastectomy reconstruction: An update on oncological and reconstruction techniques

Nipple-sparing mastectomy(NSM) is a safe technique in patients who are candidates for conservation breast surgery. However, there is worry concerning its oncological safety and surgical outcome in terms of postoperative complications. The authors reviewed the literature to evaluate the oncological safety, patient selection, surgical techniques, and also to identify the factors influencing postoperative outcome and complication rates. Patient selection and safety related to NSM are based on oncological and anatomical parameters. Among the main criteria, the oncological aspects include the clinical stage of breast cancer, tumor characteristics and location including small, peripherally located tumors, without multicentricity, or for prophylactic mastectomy. Surgical success depends on coordinated planning with the oncological surgeon andcareful preoperative and intraoperative management. In general, the NSM reconstruction is related to autologous and alloplastic techniques and sometimes include contra-lateral breast surgery. Choice of reconstructive technique following NSM requires accurate consideration of various patient related factors, including: breast volume, degree of ptosis, areola size, clinical factors, and surgeon's experience. In addition, tumor related factors include dimension, location and proximity to the nipple-areola complex. Regardless of the fact that there is no unanimity concerning the appropriate technique, the criteria are determined by the surgeon's experience and the anatomical aspects of the breast. The positive aspects of the technique utilized should include low interference with the oncological treatment, reproducibility, and long-term results. Selected patients can have safe outcomes and therefore this may be a feasible option for early breast cancer management. However, available data demonstrates that NSM can be safely performed for breast cancer treatment in selected cases. Additional studies and longer follow-up are necessary to define consistent selection criteria for NSM.

Current status of ultrasound-guided surgery in the treatment of breast cancer

The primary goal of breast-conserving surgery(BCS) is to obtain tumour-free resection margins. Margins positive or focally positive for tumour cells are associated with a high risk of local recurrence, and in the case of tumour-positive margins, re-excision or even mastectomy are sometimes needed to achieve definite clear margins. Unfortunately, tumour-involved margins and re-excisions after lumpectomy are still reported in up to 40% of patients and additionally, unnecessary large excision volumes are described. A secondary goal of BCS is the cosmetic outcome and one of the main determinants of worse cosmetic outcome is a large excision volume. Up to 30% of unsatisfied cosm-etic outcome is reported. Therefore, the search for better surgical techniques to improve margin status, excision volume and consequently, cosmetic outcome has continued. Nowadays, the most commonly used localization methods for BCS of non-palpable breast cancers are wire-guided localization(WGL) and radioguided localization(RGL). WGL and RGL are invasive procedures that need to be performed pre-operatively with technical and scheduling difficulties. For palpable breast cancer, tumour excision is usually guided by tactile skills of the surgeon performing "blind" surgery. One of the surgical techniques pursuing the aims of radicality and small excision volumes includes intraoperative ultrasound(IOUS). The best evidence available demonstrates benefits of IOUS with a significantly high proportion of negative margins compared with other localization techniques in palpable and non-palpable breast cancer. Additionally, IOUS is non-invasive, easy to learn and can centralize the tumour in the excised specimen with low amount of healthy breast tissuebeing excised. This could lead to better cosmetic results of BCS. Despite the advantages of IOUS, only a small amount of surgeons are performing this technique. This review aims to highlight the position of ultrasoundguided surgery for malignant breast tumours in the search for better oncological and cosmetic outcomes.

Histopathological Features of Invasion of Breast Invasive Ductal Carcinoma and Safety of Breast-conserving Surgery

In order to investigate the relationship between the extent of tumor invasion and the tumor size, axillary lymph nodes metastasis, Her-2 gene overexpression, and histologic grading in breast invasive ductal carcinoma as well as the optimal extent of excision during the breast-serving surgery, the clinical data of 104 patients with breast invasive ductal carcinoma who had received modified radical mastectomy were analyzed. The correlation analysis on invasive extent, which was evaluated by serial sections at an interval of 0.5 cm from 4 different directions taking the focus as the centre, and the tumor size, axillary lymph nodes metastasis, Her-2 gene overexpression, and his- tologic grading was processed. There was a significant correlation between invasive extent and tumor size （r=-0.766, P〈0.01）, and lymph nodes metastases 0=0.574, P〈0.01）, but there was no significant correlation between invasive extent and Her-2 expression （r=-0.106, P〉0.05）, and histologic grading （r=-0.228, P〉0.05）. The 100% negative rate of infiltration in patients without nipple discharge with tumor size 〈2, 2-3 and 〉3 cm was obtained at 1.5, 2.0 and 2.5 cm away from the tumor respectively. It is concluded that the performance of breast-serving surgery in patients with breast invasive ductal carcinoma should be evaluated by tumor size in combination with axillary lymph nodes involvement to decide the possibility of breast-serving and the secure excision extent.

Evolving role of skin sparing mastectomy

Skin sparing mastectomy(SSM) can facilitate immediate breast reconstruction and is associated with an excellent aesthetic result. The procedure is safe in selected cases; including invasive tumours < 5 cm, multi-centric tumours, ductal carcinoma in situ and for risk-reduction surgery. Inflammatory breast cancers and tumours with extensive involvement of the skin represent contraindications to SSM due to an unacceptable risk of local recurrence. Prior breast irradiation or the need for post-mastectomy radiotherapy do not preclude SSM, however the aesthetic outcome may be compromised. Preservation of the nipple areola complex is safe for peripherally located node negative tumours. An intraoperative frozen section protocol for the retro-areolar tissue should be considered in these cases. The advent of acellular tissue matrix systems has enhanced the scope of implant-based immediate reconstruction following SSM. Cell-assisted fat transfer is emerging as a promising technique to optimise the aesthetic outcome.

Oncologic Outcomes of Breast Cancer Patients Treated with Oncoplastic Surgery

Background: The impact of breast appearance after breast cancer surgical treatment on patients’ quality of life led to the development of the oncoplastic approach. However, studies reporting oncologic results associated with this treatment strategy are scarce. This cross-sectional study was designed to assess oncologic outcomes among patients who underwent oncoplastic surgery. Methods: A total of 190 breast cancer patients who underwent breast-conserving surgery were enrolled. Fifty of them underwent oncoplastic surgery and 140 had none breast reconstruction procedure (control group). All surgeries were performed by the same surgical team. Results: Groups were similar with regard to staging, histological type, grade of the tumor, presence of intraductal component, hormone receptors and nodal commitment. Patients in oncoplastic surgery group had larger tumors (ρ = 0.001) and more lymphovascular invasion (ρ = 0.047). Further, a higher proportion of them underwent chemotherapy (ρ = 0.030). Follow-up time of control group was longer (ρ = 0.05), and these patients also had a longer relapse-free survival time (ρ = 0.001). Local recurrence rate was 5.8% (11/190) and it was significantly greater in the oncoplastic surgery group (8/11, ρ = 0.001). Time to local recurrence after surgery was longer in oncoplastic surgery group (ρ = 0.002). Overall, patients in oncoplastic surgery group were younger (ρ = 0.001), but at the time of local recurrence, patients in oncoplastic surgery group were older than those in control group (ρ = 0.0002). Conclusions: Among the studied patients, local recurrence rate was greater in those who underwent oncoplastic surgery.
