Abstract
BACKGROUND Prepectoral breast reconstruction has become popularized with the concurrent use of acellular dermal matrix (ADM). The authors sought to compare 3-month postoperative complication rates and explantation rates for first-stage, tissue-expander-based, prepectoral breast reconstruction with and without the use of ADM. METHODS A single-institution retrospective chart review was performed to identify consecutive patients undergoing prepectoral tissue-expander-based breast reconstruction from August of 2020 to January of 2022. Chi-square tests were used to compare demographic categorical variables, and multiple variable regression models were used to identify variables associated with 3-month postoperative outcomes. RESULTS The authors enrolled 124 consecutive patients. Fifty-five patients (98 breasts) were included in the no-ADM cohort and 69 patients (98 breasts) were included in the ADM cohort. There were no statistically significant differences between the ADM and no-ADM cohorts with regard to 90-day postoperative outcomes. On multivariable analysis, there were no independent associations between seroma, hematoma, wound dehiscence, mastectomy skin flap necrosis, infection, unplanned return to the operating room, or explantation in the ADM and no-ADM groups after controlling for age, body mass index, history of diabetes, tobacco use, neoadjuvant chemotherapy, and postoperative radiotherapy. CONCLUSIONS The authors' results reveal no significant differences in odds of postoperative complications, unplanned return to the operating room, or explantation between the ADM and no-ADM cohorts. More studies are needed to evaluate the safety of prepectoral, tissue expander placement without ADM. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

How Porcine Acellular Dermal Matrix Influences the Development of the Breast Capsule 1 Year after Implantation: A Histopathological Analysis. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2023; 11:e5400. [PMID: 38025625 PMCID: PMC10656090 DOI: 10.1097/gox.0000000000005400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 09/20/2023] [Indexed: 12/01/2023]
Abstract
Background In prepectoral breast reconstruction (PPBR) the acellular dermal matrix (ADM)'s integration capacity into the tissue is known. The aim of this study was to analyze the effect of the ADM on development and composition of the peri-implant breast capsule in a dynamic setting of breast tissue expansion during two-stage prepectoral breast reconstruction. Methods This is a prospective single-center study in which 50 patients who underwent mastectomy and breast reconstruction with prepectoral tissue expander and Braxon ADM (group A) and submuscular tissue expander (group B) were enrolled. One-year post implantation hematoxylin & eosin (H&E) staining and immunohistochemistry analyses were done on capsule tissue samples. Results The analysis conducted on H&E-stained samples showed a significant reduction of cellular density and a decrease of the cellular infiltration in capsules of ADM-covered expanders compared with naked expander capsules (P < 0.05). The immunohistochemical analyses showed that group A capsules presented significantly less M1 CD68+ macrophages (P < 0.05), lower alfa-SMA expression levels, and a lower number of myofibroblasts (P < 0.05) compared with group B capsules. Presence of lymphatic vessels was minimally detected in both groups. Conclusions The ADM presence around the prepectoral tissue expander influences the development of the peri-implant capsule, causing a significant reduction of the number of cells and inflammatory infiltrate, especially M1 macrophages and myofibroblasts. The ADM Braxon is therefore effective in creating a noninflamed capsule around the implant and in dynamic tissue conditions, and such an environment is maintained in time.

Should Acellular Dermal Matrices Be Used for Implant-based Breast Reconstruction after Mastectomy? Clinical Recommendation Based on the GRADE Approach. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2023; 11:e4821. [PMID: 36845868 PMCID: PMC9946425 DOI: 10.1097/gox.0000000000004821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Accepted: 12/20/2022] [Indexed: 02/24/2023]
Abstract
Acellular dermal matrices (ADMs) entered the market in the early 2000s and their use has increased thereafter. Several retrospective cohort studies and single surgeon series reported benefits with the use of ADMs. However, robust evidence supporting these advantages is lacking. There is the need to define the role for ADMs in implant-based breast reconstruction (IBBR) after mastectomy. Methods A panel of world-renowned breast specialists was convened to evaluate evidence, express personal viewpoints, and establish recommendation for the use of ADMs for subpectoral one-/two-stage IBBR (compared with no ADM use) for adult women undergoing mastectomy for breast cancer treatment or risk reduction using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Results Based on the voting outcome, the following recommendation emerged as a consensus statement: the panel members suggest subpectoral one- or two-stage IBBR either with ADMs or without ADMs for adult women undergoing mastectomy for breast cancer treatment or risk reduction (with very low certainty of evidence). Conclusions The systematic review has revealed a very low certainty of evidence for most of the important outcomes in ADM-assisted IBBR and the absence of standard tools for evaluating clinical outcomes. Forty-five percent of panel members expressed a conditional recommendation either in favor of or against the use of ADMs in subpectoral one- or two-stages IBBR for adult women undergoing mastectomy for breast cancer treatment or risk reduction. Future subgroup analyses could help identify relevant clinical and pathological factors to select patients for whom one technique could be preferable to another.

Abstract
BACKGROUND Direct-to-implant (DTI) breast reconstruction is one of the immediate implant-based breast reconstruction methods. If the amount of soft tissue (eg, muscle or fascia) is insufficient to completely cover the implant, biological scaffold or acellular dermal matrix can be safely used for implant coverage. In this study, we used an acellular porcine small intestinal submucosa (SIS) mesh (Biodesign; Cook Medical Inc, Bloomington, IN) for DTI reconstruction to explore the impact of its use on breast reconstruction results. METHODS We retrospectively assessed cases involving DTI reconstruction at Taipei Veterans General Hospital from 2015 to 2019. Women, 18 years or older, who underwent immediate DTI reconstruction after mastectomy were included in the study. Mastectomy may have been performed because of therapeutic or prophylactic reasons. Patients who did and did not use SIS mesh for reconstruction were studied separately, and the 2 groups were compared in terms of clinical outcomes and complications. The validated, self-administered BREAST-Q Reconstruction Module version 2.0 survey was used to evaluate health-related quality of life and satisfaction among patients who underwent breast reconstruction. RESULTS A total of 30 DTI breast reconstructions were enrolled. The mean age was 49.2 years, and the mean body mass index was 22.3 kg/m2. The mean postoperative follow-up duration was 17.1 months. Nipple-sparing mastectomy was performed for 26 cases (86.7%), and DTI breast reconstructions using SIS mesh for implant coverage were done in 14 cases (46.7%). The overall complication rate was 53.3% in 30 reconstructions, with nipple complications being the most common complication. The non-SIS and SIS-using groups had a similar overall complication rate postoperatively. As for the quality-of-life assessment, the SIS group obtained a higher score on BREAST-Q than those for whom SIS was not used. CONCLUSIONS Porcine SIS mesh might be a safe and effective alternative to biological scaffolds in immediate 1-stage implant-based breast reconstruction to improve the quality of life after surgery.

BROWSE: A multicentre comparison of nine year outcomes in acellular dermal matrix based and complete submuscular implant-based immediate breast reconstruction-aesthetics, capsular contracture and patient reported outcomes. Eur J Surg Oncol 2021; 48:73-81. [PMID: 34836730 DOI: 10.1016/j.ejso.2021.10.026] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 10/21/2021] [Accepted: 10/27/2021] [Indexed: 12/14/2022] Open
Abstract
Approximately 60% of implant-based breast reconstructions (IBBR) are performed with an acellular dermal matrix (ADM), for which, reliable, good quality long-term outcome data is limited. In a retrospective multicentre cohort study, we aimed to determine long-term aesthetic and quality of life outcomes of IBBR with ADM (Strattice™) compared to a submuscular technique. METHODS Capsular contracture (Baker III/IV capsule) was determined by clinical examination by an independent researcher. Quality of life was assessed using BREAST-Q and aesthetic outcome by photographic assessment from a breast surgeon, breast care nurse and lay person, blinded to reconstruction type. RESULTS We recruited 117 (51 bilateral) patients with ADM reconstructions, median follow-up 62 months (range 29-113) and 49 patients (16 bilateral) with submuscular reconstructions, median follow-up 76 months (range 38-111). 17 (10.1%) ADM reconstructions were Baker 3/4 compared to six (9.2%) submuscular (p = 0.85). Of the Baker 1/2 reconstructions six (3.6%) ADM and eight (13.6%) submuscular had previously undergone revision surgery to correct capsular contracture (p = 0.01). Combining both findings gave an estimated rate of capsular contracture of 13.6% in the ADM group and 21.2% in the submuscular (p = 0.14). A higher mean score for satisfaction with breasts was demonstrated when comparing ADM to submuscular (62 and 55, respectively; p = 0.01) but no significant difference in other BREAST-Q domains. The mean 'general satisfaction' score was higher in the ADM group for all three photograph assessors. CONCLUSION This study provides evidence of improved aesthetic outcome and reduction in capsular contracture with ADM reconstruction when compared to submuscular, consistent over long-term follow-up.

Abstract
BACKGROUND Capsular contracture is a well-recognized complication following prosthetic breast reconstruction. It has been the authors' observation that some patients undergoing breast reconstruction experience contracture specifically of the acellular dermal matrix placed at the time of their tissue expander insertion. The goal of the authors' study was to identify clinical and histologic findings associated with the development of acellular dermal matrix-associated contracture. METHODS The authors performed a retrospective cohort study of all patients undergoing bilateral implant-based breast reconstruction performed by the senior author (M.S.A.). Patients were excluded if they had radiation therapy to the breast. Patients with suspected acellular dermal matrix-associated contracture were identified by clinical photographs and review of operative notes. Histologic analysis was performed on specimens taken from two patients with acellular dermal matrix contracture. RESULTS The authors included a total of 46 patients (92 breasts), of which 19 breasts had suspected acellular dermal matrix-associated contracture. Acellular dermal matrix contracture was less common in direct-to-implant reconstruction (4.2 percent versus 26.5 percent; p = 0.020) and more common in breasts that had seromas (0 percent versus 15.8 percent; p = 0.001) or complications requiring early expander replacement. Contracted acellular dermal matrix had less vascularity and a lower collagen I-to-collagen III ratio, and was twice as thick as noncontracted acellular dermal matrix. CONCLUSIONS The authors have described a distinct phenomenon of acellular dermal matrix-associated contracture that occurs in a small subset of breasts where acellular dermal matrix is used. This merits further investigation. Future work will be required to better characterize the clinical factors that make acellular dermal matrix-associated contracture more likely to occur.

Abstract
Background and objectives: Breast cancer treatment has deeply changed in the last fifty years. Acellular dermal matrices (ADMs) were introduced for breast reconstruction, with encouraging results, but with conflicting reports too. The present paper aims to summarize the current data on breast reconstruction using acellular dermal matrices. Materials and Methods: We reviewed the literature regarding the use of ADM-assisted implant-based breast reconstruction. Results: The main techniques were analyzed and described. Conclusions: Several authors have recently reported positive results. Nevertheless, an increased complications' rate has been reported by other authors. Higher cost compared to not-ADM-assisted breast reconstruction is another concern.

Radiat Oncol 2020; 15:52. [PMID: 32111228 PMCID: PMC7049187 DOI: 10.1186/s13014-020-01499-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Accepted: 02/18/2020] [Indexed: 12/11/2022] Open
Abstract
Background Three-dimensional Surface Imaging (3DSI) is a well-established method to objectively monitor morphological changes in the female breast in the field of plastic surgery. In contrast, in radiation oncology we are still missing effective tools, which can objectively and reproducibly assess and document adverse events in breast cancer radiotherapy within the framework of clinical studies. The aim of the present study was to apply structured-light technology as a non-invasive and objective approach for the documentation of cosmetic outcome and early effects of breast radiotherapy as a proof of principle. Methods Weekly 3DSI images of patients receiving either conventionally fractionated radiation treatment (CF-RT) or hypofractionated radiation treatment (HF-RT) were acquired during the radiotherapy treatment and clinical follow-up. The portable Artec Eva scanner (Artec 3D Inc., Luxembourg) recorded 3D surface images for the analysis of breast volumes and changes in skin appearance. Statistical analysis compared the impact of the two different fractionation regimens and the differences between the treated and the contralateral healthy breast. Results Overall, 38 patients and a total of 214 breast imaging sessions were analysed. Patients receiving CF-RT showed a significantly higher frequency of breast erythema compared to HF-RT (93.3% versus 34.8%, p = 0.003) during all observed imaging sessions. Moreover, we found a statistically significant (p < 0.05) volumetric increase of the treated breast of the entire cohort between baseline (379 ± 196 mL) and follow-up imaging at 3 months (437 ± 224 mL), as well as from week 3 of radiotherapy (391 ± 198 mL) to follow-up imaging. In both subgroups of patients undergoing either CF-RT or HF-RT, there was a statistically significant increase (p < 0.05) in breast volumes between baseline and 3 months follow-up. There were no statistically significant skin or volumetric changes of the untreated healthy breasts. Conclusions This is the first study utilizing 3D structured-light technology as a non-invasive and objective approach for the documentation of patients receiving breast radiotherapy. 3DSI offers potential as a non-invasive tool to objectively and precisely monitor the female breast in a radiooncological setting, allowing clinicians to objectively distinguish outcomes of different therapy modalities.
