Abstract
INTRODUCTION Post-mastectomy radiotherapy (PMRT) improves local control rates and survival in patients with adverse prognostic features. The dose coverage to target volumes is critical to yield maximum benefit to treated patients, increasing local control and reducing risk of toxicity. This study aims to assess patterns of breast cancer relapse in patients treated with mastectomy, breast reconstruction and PMRT. METHODS Breast cancer patients treated with PMRT between 1992 and 2017 were retrospectively reviewed. Clinical and pathological characteristics of patients were collected. Recurrences were defined as "in field," "marginal" or "out of field." Survival analyses were performed in relation to progression-free survival (PFS) and overall survival (OS). Correlation between baseline features was explored. RESULTS Data of 140 patients are collected. After a median follow-up time of 72 months, median PFS and OS of 63 and 74 months were detected, respectively. Neoadjuvant chemotherapy, lympho-vascular space invasion (LVI) and size of primary tumor were all significantly associated with worst PFS and OS. Ten patients developed local recurrence: 30% "in field," 30% marginal recurrences, 20% "out of field" and 20% both "in field" and "out of field." No recurrence was detected under the expander, 80% above the device and 20% patients relapsed on IMN chain. The mean distant relapse-free survival was 39 months. Overall, 39 of 140 patients developed distant metastases. CONCLUSIONS The onset of local-regional relapses occurred mainly above the expander/prosthesis, underlying the importance of inclusion of the subcutaneous tissues within the target volume. In order to refine new contouring recommendations for PMRT and breast reconstruction, future prospective studies are needed.

A Phase II Study Evaluating the Effect of Intensity Modulated Postmastectomy Radiation Therapy on Implant Failure Rates in Breast Cancer Patients With Immediate, 2-Stage Implant Reconstruction With an MRI Imaging Correlative Substudy. Int J Radiat Oncol Biol Phys 2024:S0360-3016(24)00451-6. [PMID: 38570168 DOI: 10.1016/j.ijrobp.2024.03.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 03/11/2024] [Accepted: 03/20/2024] [Indexed: 04/05/2024]
Abstract
PURPOSE Postmastectomy radiation therapy is a mainstay in the adjuvant treatment of node-positive breast cancer, but it poses risks for women with breast reconstruction. Multibeam intensity-modulated radiation therapy improves dose conformality and homogeneity, potentially reducing complications in breast cancer patients with implant-based reconstruction. To investigate this hypothesis, we conducted a single-arm phase 2 clinical trial of breast cancer patients who underwent mastectomy/axillary dissection and prosthesis-based reconstruction. METHODS AND MATERIALS The primary endpoint was the rate of implant failure (IF) within 24 months of permanent implant placement, which would be considered an improvement over historical controls if below 16%. IF was defined as removal leading to a flat chest wall or replacement with another reconstruction. Patients were analyzed in 2 cohorts. Cohort 1 (RT-PI) received radiation therapy to the permanent implant. Cohort 2 (RT-TE) received radiation therapy to the TE. IF rates, adverse events, and quality of life were analyzed. Follow-up/postradiation therapy assessments were compared with the baseline/preradiation therapy assessments at 3 to 10 weeks after exchange surgery. A subgroup underwent serial magnetic resonance imaging (MRI) sessions to explore the association between MRI-detected changes and capsular contracture, a known adverse effect of radiation therapy. RESULTS Between June 2014 and March 2017, 119 women were enrolled. Cohort 1 included 45 patients, and cohort 2 had 74 patients. Among 100 evaluable participants, 25 experienced IF during the study period. IF occurred in 8/42 (19%) and 17/58 (29%) in cohorts 1 and 2, respectively. Among the IFs, the majority were due to capsular contracture (13), infection (7), exposure (3), and other reasons (2). Morphologic shape features observed in longitudinal MRI images were associated with the development of Baker grade 3 to 4 contractures. CONCLUSIONS The rate of IF in reconstructed breast cancer patients treated with intensity-modulated radiation therapy was similar to, but not improved over, that observed with conventional, 3-dimensional-conformal methods. MRI features show promise for predicting capsular contracture but require validation in larger studies.

Abstract
OBJECTIVES To describe the usage and advantages of bovine pericardium mesh (Tutopatch®) in breast reconstruction and to compare different mesh materials used in immediate breast reconstruction. METHODS Our study involved a single-center, retrospective analysis of 103 patients (comprising 114 breasts) who underwent immediate implant-based breast reconstruction using bovine pericardium bovine matrix. The procedures were performed by the same surgical team between April 2018 and May 2023. RESULTS The rates of early and late complications were examined after a median follow-up period of 30.2 ± 5.5 months. The results revealed that the rates of early complications stood at 9.7%, while late complications were observed in 14.5% of the cases. The most common late complication was seroma formation (7.7%) which six were resolved without any surgical intervention. CONCLUSION Tutopatch® can be used as an extension of the muscle to cover the prosthesis. It forms an extra layer over the silicone implant that helps to decrease the complications as capsular contracture and implant exposure. It also represents a significant 85 % reduction in cost when compared to a similar-sized mesh materials.

Abstract
Our study aims to identify the risk factors and dosimetry characteristics associated with capsular contracture. METHODS We retrospectively analyzed 118 women with breast cancer who underwent PMRT following an IBR between 2010 and 2022. Patients were treated with PMRT of 50.0-50.4 Gy in 25-28 fractions. Capsular contracture was categorized according to the Baker Classification for Reconstructed Breasts. RESULTS After a median follow-up of 22 months, the incidence of clinically relevant capsular contracture (Baker III-IV) was 22.9%. Overall, capsular contracture (Baker I-IV) occurred in 56 patients (47.5%) after a median of 9 months after PMRT. The rate of reconstruction failure/implant loss was 25.4%. In the univariate analysis, postoperative complications (prolonged pain, prolonged wound healing, seroma and swelling) and regional nodal involvement were associated with higher rates of capsular contracture (p = 0.017, OR: 2.5, 95% CI: 1.2-5.3 and p = 0.031, respectively). None of the analyzed dosimetric factors or the implant position were associated with a higher risk for capsular contracture. CONCLUSION Postoperative complications and regional nodal involvement were associated with an increased risk of capsular contracture following breast reconstruction and PMRT, while none of the analyzed dosimetric factors were linked to a higher incidence. Additional studies are needed to identify further potential risk factors.

Abstract
INTRODUCTION Capsular contracture remains the most common complication following device-based breast reconstruction, occurring in up to 50% of women who also undergo adjuvant radiotherapy either before or after device-based reconstruction. While certain risk factors for capsular contracture have been identified, there remains no clinically effective method of prevention. The purpose of the present study is to determine the effect of coating the implant with the novel small molecule Met-Z2-Y12, with and without delayed, targeted radiotherapy, on capsule thickness and morphologic change around smooth silicone implants placed under the latissimus dorsi in a rodent model. METHODS Twenty-four female Sprague Dawley rats each had 2 mL smooth round silicone breast implants implanted bilaterally under the latissimus dorsi muscle. Twelve received uncoated implants and twelve received implants coated with Met-Z2-Y12. Half of the animals from each group received targeted radiotherapy (20 Gray) on postoperative day ten. At three and 6 months after implantation, the tissue surrounding the implants was harvested for analysis of capsular histology including capsule thickness. Additionally, microCT scans were qualitatively analyzed for morphologic change. RESULTS Capsules surrounding Met-Z2-Y12-coated implants were significantly thinner (P = 0.006). The greatest difference in capsule thickness was seen in the irradiated 6-month groups, where mean capsule thickness was 79.1 ± 27.3 μm for uncoated versus 50.9 ± 9.6 μm for Met-Z2-Y12-coated implants (P = 0.038). At the time of explant, there were no capsular morphologic differences between the groups either grossly or per microCT. CONCLUSIONS Met-Z2-Y12 coating of smooth silicone breast implants significantly reduces capsule thickness in a rodent model of submuscular breast reconstruction with delayed radiotherapy.

Abstract
Breast remodelling is a major therapeutic choice in radical mastectomy. Breast reconstruction is regarded as a promising option for the treatment of breast cancer. The purpose of this meta-analysis was to investigate the effect of Post mastectomy radiotherapy (PMRT) on postoperative wound complications in breast carcinoma. A comprehensive review of documents was conducted between the date of establishment and the 28th of August 2023. In all of the trials, patients were treated with breast cancer. The researchers chose 11 publications out of 8068 related studies. Two researchers examined these publications to satisfy the inclusion criteria. Among the 516 patients who had received radiation therapy in the course of the operation, 1772 had not received radiation therapy. The impact of radiation therapy and non-radiation therapy in breast cancer patients after breast reconstruction was reported in 8 studies, and the incidence of postoperative wound infection in non-radiation group was significantly lower (OR, 1.95; 95% CI, 1.26-3.02 p = 0.003). In nine studies, There is not considered to have achieved statistical significance between radiation therapy and non-radiation treatment for post-operation wound dehiscence in breast cancer patients who had received chemotherapy (OR, 1.61; 95% CI, 0.70-3.72 p = 0.27). The results of six trials demonstrated that radiation therapy and non-radiation therapy had no statistical significance on post-operation haemorrhage in breast cancer patients (OR, 1.02; 95% CI, 0.42-2.47 p = 0.96). The results of 7 trials demonstrated that radiation therapy and non-radiation therapy had no significant impact on the post-operation of skin necrosis (OR, 1.22; 95% CI, 0.66-2.28 p = 0.53). Two trials demonstrated that those without radiation therapy were less likely than those who received radiation therapy in skin contracture in patients (OR, 7.24; 95% CI, 1.80-29.10 p = 0.005). Regarding the incidence of wound infection and cutaneous contraction was higher in the radiation group.

Abstract
BACKGROUND This study was performed to evaluate the hypothesis that capsule formation varies according to the radiation dose in muscle tissues; chest wall tissues, including the ribs; and acellular dermal matrices (ADM) that are in contact with the silicone implant. METHODS In this study, 20 Sprague-Dawley rats underwent submuscular plane implant reconstruction using ADM. They were divided into four groups: an unradiated control group ( n = 5), nonfractionated radiation at a dose of 10 Gy ( n = 5), nonfractionated radiation at a dose of 20 Gy ( n = 5), and fractionated radiation at a dose of 35 Gy ( n = 5). Three months after surgery, hardness was measured, and histologic and immunochemical analyses of the capsule tissues of the ADM, muscle tissues, and chest wall tissues were analyzed. RESULTS As the radiation dose increased, the silicone implant became harder, but no significant difference in capsule thickness according to the radiation dose was observed. Based on the tissue in contact with the silicone implant, ADM had a thinner capsule thickness than the muscle tissues, as well as less inflammation and less neovascularization compared with the other tissues. CONCLUSIONS This study describes a new rat model of clinically relevant implant-based breast reconstruction using a submuscular plane and ADM with irradiation. The ADM in contact with the silicone implant, even after irradiation, was protected from radiation compared with the other tissues. CLINICAL RELEVANCE STATEMENT These research results could support the use of ADM in implant-based breast reconstruction for prevention of the capsular contracture, even after radiation.

Abstract
BACKGROUND The body responds to prosthetic materials with an inflammatory foreign body response and deposition of a fibrous capsule, which may be deleterious to the function of the device and cause significant discomfort for the patient. Capsular contracture (CC) is the most common complication of aesthetic and reconstructive breast surgery. The source of significant patient morbidity, it can result in pain, suboptimal aesthetic outcomes, implant failure, and increased costs. The underlying mechanism remains unknown. Treatment is limited to reoperation and capsule excision, but recurrence rates remain high. In this study, the authors altered the surface chemistry of silicone implants with a proprietary anti-inflammatory coating to reduce capsule formation. METHODS Silicone implants were coated with Met-Z2-Y12, a biocompatible, anti-inflammatory surface modification. Uncoated and Met-Z2-Y12-coated implants were implanted in C57BL/6 mice. After 21, 90, or 180 days, periprosthetic tissue was removed for histologic analysis. RESULTS The authors compared mean capsule thickness at three time points. At 21, 90, and 180 days, there was a statistically significant reduction in capsule thickness of Met-Z2-Y12-coated implants compared with uncoated implants ( P < 0.05). CONCLUSIONS Coating the surface of silicone implants with Met-Z2-Y12 significantly reduced acute and chronic capsule formation in a mouse model for implant-based breast augmentation and reconstruction. As capsule formation obligatorily precedes CC, these results suggest contracture itself may be significantly attenuated. Furthermore, as periprosthetic capsule formation is a complication without anatomical boundaries, this chemistry may have additional applications beyond breast implants, to a myriad of other implantable medical devices. CLINICAL RELEVANCE STATEMENT Coating of the silicone implant surface with Met-Z2-Y12 alters the periprosthetic capsule architecture and significantly reduces capsule thickness for at least 6 months postoperatively in a murine model. This is a promising step forward in the development of a therapy to prevent capsular contracture.

Decreasing Time Intervals in Recurring Capsular Contracture? A Single Center Retrospective Study over 6 Years. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2023; 11:e4872. [PMID: 36910725 PMCID: PMC10005826 DOI: 10.1097/gox.0000000000004872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 01/26/2023] [Indexed: 03/12/2023]
Abstract
Although breast implants of the current generation can, in principle, remain in the body for life, follow-up operations of the augmented or reconstructed breasts are regularly necessary. Capsular contracture is the leading cause for revisional surgery. The aim of this study was to evaluate indications and changes in time intervals between consecutive implant replacements with a focus on capsular contracture. Methods In the period from 2012 to 2017, all patients with breast implant replacements or removals at our institution were identified. From the medical file, the time of the first implantation and earlier replacements were analyzed for indication and timing of surgery. Results A total of 498 operations for implant replacement or removal were analyzed in 323 patients. Including prior operations, 717 procedures could be evaluated. If capsular contracture was the indication, revision surgery was performed on average 14.3 years or 8.4 years in aesthetic or reconstructive cases, respectively. In patients with more than one implant removal or replacement, we saw a reduction in the time interval between the first, second, and third follow-up operation. Conclusions The main indication to perform implant replacements or removals was capsular contracture recurring at increasingly shorter intervals. Patients must be informed about this possible progression when changing implants, but also before the first operation. If capsular contracture occurs after a rather short time period in reconstructive cases, the opportunity of an alternative approach (eg, autologous reconstruction) instead of a renewed implant change should be discussed with the patient.

Abstract
INTRODUCTION Short course regimen has become the major trend in the field of adjuvant radiotherapy for patients with breast cancer. Hypofractionated radiotherapy (HF-RT) regimen of 40-42.5 Gy in 15-16 fractions has been established as a preferred option for whole breast irradiation. However, few evidences of hypofractionated regional nodal irradiation (RNI), especially involving internal mammary nodes (IMNs), could be available during the era of intensity-modulated radiation therapy (IMRT). Against this background, we design this trial to explore the hypothesis that HF-RT regimen involving RNI (including infraclavicular, supraclavicular nodes and IMNs) will be non-inferior to a standard schedule by using IMRT technique. METHODS AND ANALYSIS This is an open-label randomised, non-inferior, multicentre phase III trial. Patients with breast cancer with an indication for RNI after breast conserving surgery or mastectomy are randomised at a ratio of 1:1 into the following two groups: hypofractionated regimen of 2.67 Gy for 16 fractions or conventional regimen of 2 Gy for 25 fractions. The dose was prescribed to ipsilateral chest wall or whole breast and RNI (including infraclavicular, supraclavicular nodes and IMNs, lower axilla if indicated). The trial plans to enrol a total of 801 patients and all patients will be treated using IMRT technique. The primary endpoint is 5-year locoregional recurrence. The secondary endpoints include 5-year distant metastasis free survival, invasive recurrence-free survival, overall survival, accumulative acute radiation-induced toxicity and accumulative late radiation-induced toxicity, cosmetic outcomes and quality of life. ETHICS AND DISSEMINATION The study has been approved by the Ethical Committee of Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine (version 2018-95-3) and approvals from ethical committee of each participating centre have also been obtained. Research findings will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT03829553.

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
AIM To evaluate reconstruction failure (RF) rate in patients receiving implant-based immediate breast reconstruction (IBR) and hypofractionated (HF) postmastectomy radiation therapy (PMRT). MATERIALS AND METHODS Stage II-III breast cancer patients, treated with HF-PMRT using intensity modulated radiotherapy were stratified in two groups according to IBR: single-stage direct-to-implant (DTI-group) and two-stage expander and implant (TE/I-group). Irradiated patients were matched with non-irradiated ones who underwent the same IBR during the same period. Prescription dose was 40.05 Gy/15 fractions to chest wall and infra/supraclavicular nodal region. Primary endpoint was RF defined as the need of major revisional surgery (MaRS) for implant removal or conversion to autologous reconstruction. Secondary endpoint was the rate of minor revisional surgeries (MiRS) including implant repositioning or substitution with another implant. RESULTS One hundred and seven irradiated patients (62 in TE/I-group, 45 in DTI-group) were matched with 107 non-irradiated subjects. Median follow-up was 4.2 years (0.1-6.1) In the TE/I setting, MaRS was performed in 8/62 irradiated patients (12.9%) of the irradiated TE/I group compared to 1/62 (1.6%) non-irradiated subjects (p = 0.015). In the DTI setting, MaRs occurred in 3/45 irradiated patients (6.7%) compared to 1/45 non-irradiated ones (2.2%) (p = 0.35). Overall MaRS rate was 10.3% in the irradiated group. MiRS was performed in 35.6% and 31.1% of the irradiated and non-irradiated DTI-groups (p = 0.65), respectively, and in 12.9% and 8.1% of the irradiated and non-irradiated TE/I groups (p = 0.38), respectively. CONCLUSIONS Compared to the non-irradiated counterparts, the TE/I group showed higher rate of RF, while no statistically significant difference was observed for the DTI group. The use of hypofractionation and IMRT to implant-based IBR did not seem to increase the risk of RF which appeared to be in line with the literature.

Abstract
BACKGROUND/AIM For women who have undergone a mastectomy, breast reconstruction provides psychological as well as aesthetic benefits. Thus, many patients ask for an immediate breast reconstruction (IBR). The present study focuses on risk factors assiociated with complications after IBR. PATIENTS AND METHODS A national prospective study (2007-2009) was conducted on 404 patients who underwent an unilateral IBR: 205 implants alone (IA) including 46 tissue expanders, 91 latissimus dorsi musculocutaneous flaps with implant (LDI), 78 autologous latissimus dorsi musculocutaneous flaps (LD), and 30 autologous transverse rectus abdominis musculocutaneous flaps (TRAM). Outcomes concerned major and minor complications, as well as early and late complications. RESULTS Related risks of complications were different according to the IBR technique. Major complications rate remained moderate and concerned 15% of patients. Obesity and diabetes significantly increased the incidence of major complications. CONCLUSION To reduce complication rate, the risk factors associated with each type of IBR should be taken into account.

Abstract
BACKGROUND Results regarding immediate prosthetic breast reconstruction after postmastectomy radiation therapy (PMRT) have been inconsistent. OBJECTIVES The authors aimed to assess the efficacy and safety of PMRT before immediate prosthetic breast reconstruction for patients with breast cancer. METHODS Electronic databases (PubMed, EmBase, and the Cochrane Library) were systematically searched to identify eligible studies from their inception until March 2020. The pooled odds ratio (OR) with 95% confidence intervals (CIs) was applied as an effect estimate and calculated using the random-effects model. RESULTS Nineteen studies including a total of 6757 patients were selected for final meta-analysis. The pooled OR showed that PMRT was associated with a higher incidence of reconstruction failure (OR = 2.57; 95% CI =1.55-4.26; P < 0.001), capsular contracture (OR = 5.99; 95% CI = 3.12-11.47; P < 0.001), and overall complications (OR = 2.52; 95% CI = 1.68-3.79; P < 0.001). It was also associated with a lower incidence of patient satisfaction (OR = 0.29; 95% CI = 0.16-0.52; P < 0.001) and good aesthetic results (OR = 0.25; 95% CI = 0.12-0.52; P < 0.001) compared with those who did not undergo PMRT. These significant associations could be affected by study design, mean age, stage of immediate breast reconstruction, follow-up, and study quality. CONCLUSIONS Although PMRT is the standard adjuvant therapy for mastectomy patients treated with immediate implant-based breast reconstruction, PMRT for patients undergoing immediate implant-based breast reconstruction has been associated with high risks of reconstruction failure, capsular contracture, and overall complications as well as low incidences of patient satisfaction and good aesthetic results.

Abstract
PURPOSE Capsular contracture (CC) is a troublesome complication after breast surgery with breast implants, and the risk increases in breast cancer patients after radiotherapy. Studies investigating leukotriene antagonists (eg, montelukast, zafirlukast) found that the acellular dermal matrix (ADM) can help prevent CC. We aimed to compare the effects of ADM and montelukast on CC after irradiation. METHODS Eighteen New Zealand white rabbits were randomly divided into 3 groups of 6 each. Miniature cohesive gel implants were inserted into the pocket under the latissimus dorsi muscle. The lateral part was uncovered by the latissimus dorsi muscle. Six animals were included in the control group. In experimental group A (EG-A) (n = 6), the site was partially wrapped with ADM but not covered with muscle. Montelukast (Singulair, 0.2 mg/kg) was administered in experimental group B (EG-B) (n = 6) daily. Groups were irradiated at postoperative day 21 with Co-60 γ rays (25 Gy, single fraction) at the peri-implant area. Rabbits were sacrificed 12 weeks after surgery; implants with peri-implant capsule were harvested. Capsule thickness, collagen pattern, myofibroblast, and transforming growth factor (TGF) β1/2 levels in the peri-implant capsule were evaluated. RESULTS On histological evaluation, the capsule was thinner on the lateral aspect (covered with ADM) in EG-A (P = 0.004) and the entire capsule in EG-B (P = 0.004) than in the control group. However, there was no significant difference between EG-A and EG-B (P = 0.073). The collagen distribution pattern was more parallel with low density in the lateral capsular aspect in EG-A, but in the entire capsule in EG-B. The myofibroblast amount (EG-A, P = 0.031; EG-B, P = 0.016) and levels of TGF-β1 and TGF-β2 were reduced in the experimental groups (TGF-β1, EG-A, P = 0.019; TGF-β1, EG-B, P = 0.045; TGF-β2, EG-A, P = 0.018; TGF-β2, EG-B, P = 0.022). There was no significant difference between EG-A and EG-B (myofibroblast, P = 0.201; TGF-β1, P = 0.665; TGF-β2, P = 0.665). CONCLUSIONS Acellular dermal matrix and montelukast have a prophylactic effect for CC even when the breast is irradiated. There was no significant difference between ADM and montelukast in preventing capsular formation. The difference is that ADM will only have the effect of covering the capsular formation with ADM and montelukast can cause systemic effects or complications.

The Use of Local Perforator Flaps in Delayed or Secondary Breast Reconstruction. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2020; 8:e3263.

Abstract
Supplemental Digital Content is available in the text. Local perforator flaps are used as immediate volume replacement techniques in breast conserving surgery. Here, we describe a case series of local perforator flaps used in the delayed setting to correct defects following previous breast surgery, including previous breast conservation surgery or mastectomy with reconstruction. All cases were performed in a tertiary referral breast unit between 2014 and 2020. Cases were identified using a prospectively maintained database. Indications, type of perforator flap used, immediate post-operative complications, and longer term outcomes were recorded. Fifteen cases were identified: 8 following previous breast conserving surgery and radiotherapy, 6 following mastectomy and reconstruction, and 1 for developmental breast asymmetry following childhood radiotherapy. Indications included volume deficit, contour defect, asymmetry, and capsular contracture. One patient a major complication requiring return to theater due to implant-related infection. There were no flap losses. Longer term, 2 patients underwent lipomodeling to further augment breast volume as part of a planned, staged revision. One patient subsequently elected to have bilateral breast implant exchange to increase volume. Our series shows the versatility of local perforator flaps in the correction of complex breast defects that can occur following previous breast surgery. Delayed local perforator flaps are associated with low morbidity, and further revision surgery is not commonly required.

Abstract
BACKGROUND Acellular dermal matrices have been introduced to optimize direct-to-implant breast reconstruction. We selected a bovine pericardium noncross-linked matrix. METHODS The study consists in the retrospective analysis of 123 patients (141 breasts) who underwent conservative mastectomy and immediate implant-based breast reconstruction with bovine pericardium matrix Veritas® from March 2012 to October 2017. RESULTS The overall rates of early and late complications, after a median follow-up of 51.84 months, were, respectively, 37.6% and 24.1%. The most noticeable early complications were flap ischemia [n = 39 (27.7%)], hematoma [n = 5 (3.6%)], marginal skin flap necrosis [n = 5 (3.6%)] and dehiscence of the surgical wound [n = 2 (1.4%)]. The most common late complications were rippling [n = 18 (12.7%)] and seroma [n = 4 (2.8%)]. The rate of clinically relevant capsular contracture was low: 12.1% (n = 17) presented grade II and only 2.1%% (n = 3) grade III. Implant substitution became necessary for five patients (3.6%). Early complications occurred more frequently in patients undergoing therapeutic mastectomy (p = 0.031). Patients undergoing preoperative radiotherapy more frequently developed late complications (p = 0.012). A clinically relevant capsular contracture (grade II-III) was found in higher average patients age (p = 0.0019). The left side developed less frequently late complications except for rippling (p = 0.002). Rippling occurred more frequently in patients who sustained a nipple skin-sparing mastectomy (p = 0.035). CONCLUSION Our results further support the safety of Veritas® in immediate implant-based breast reconstruction.

Immediate Breast Reconstruction after mastectomy with polyurethane implants versus textured implants: A retrospective study with focus on capsular contracture. Breast 2020; 54:127-132. [PMID: 33010626 PMCID: PMC7529839 DOI: 10.1016/j.breast.2020.09.009] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 09/06/2020] [Accepted: 09/22/2020] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Capsular contracture (CC) is the most common complication following Immediate Breast Reconstruction (IBR) with breast implants. Different implant surfaces were developed aiming to reduce the incidence of CC. We evaluated the incidence and degree of CC after Direct-to-Implant (DTI) IBR with insertion of textured (TE) or polyurethane (PU) covered implants. METHODS A retrospective review of consecutive patients treated at our Institution with mastectomy and one-stage IBR and implant reconstruction between 2013 and 2018, with or without post mastectomy radiation therapy (PMRT), was conducted. Immediate breast reconstruction was performed by implanting 186 PU covered implants and 172 TE implants. RESULTS Three-hundred-twelve women underwent 358 DTI IBR with PU or TE implants, were analyzed with a median follow-up time of 2.3 years (range 1.0-3.0). The overall rate of CC Baker grade III and IV was 11.8% (95%CI: 8.4-16.3), while, after PU and TE implant placement it was 8.1% (95% CI: 4.1-15.7) and 15.8% (95% CI: 4.1-15.7) [p = 0.009]), respectively. Irradiated breasts developed CC more frequently rather than non-irradiated breasts (HR = 12.5, p < 0.001), and the relative risk was higher in the TE group compared with the PU group (HR = 0.3, p = 0.003). CONCLUSIONS After mastectomy and one-stage IBR, the use of PU covered implants is associated with a lower incidence of CC compared to TE implants. This advantage is amplified several folds for patients who necessitate PMRT.

Hypofractionated Radiotherapy With Volumetric Modulated Arc Therapy Decreases Postoperative Complications in Prosthetic Breast Reconstructions: A Clinicopathologic Study. Front Oncol 2020; 10:577136. [PMID: 33282731 PMCID: PMC7705232 DOI: 10.3389/fonc.2020.577136] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Accepted: 10/20/2020] [Indexed: 11/13/2022] Open
Abstract
Background Emerging radiation technologies are expected to provide a positive impact on the reduction in postoperative complications in patients receiving prosthetic breast reconstruction. This study aimed to determine whether hypofractionated radiation therapy(RT) with volumetric modulated arc therapy(VMAT) is superior to conventional RT in the setting of prosthetic reconstruction. Methods From retrospective data collections, postoperative complications were compared for all patients with mastectomy and staged prosthetic reconstruction without RT, with hypofractionation using 40 Gy in 15 fractions with VMAT (Hypo-VMAT) or conventional RT (50 Gy over 5 weeks). After harvesting subpectoral capsules from patients with informed consents, histologic analysis including immunohistochemistry and immunofluorescence for collagen type I, α-smooth muscle actin, CD34 and CD31 expression was performed. Results A total of 288 reconstructions without RT, 55 reconstructions with Hypo-VMAT, and 29 reconstructions with conventional RT were examined. During average follow-up period of 34.8 months, rates of overall complications were 6.3% in the no-radiation group, 18.2% in Hypo-VMAT group and 44.8% in conventional-RT group with significant differences (no-RT vs Hypo-VMAT: p=0.006; Hypo-VMAT vs conventional-RT: p=0.012). Levels of myofibroblasts and tissue fibrosis were lower in the Hypo-VMAT group than in conventional-RT group (p=0.016 and p=0.040, respectively), while those of progenitor cells and microvessel density were higher in the Hypo-VMAT group than in conventional-RT group (p<0.001 and p<0.001, respectively). Conclusion We demonstrated that hypofractionated RT with VMAT served to reduce radiation-related morbidities in prosthetic reconstruction from a clinicopathologic perspective, compared to conventional RT. It may offer a practical strategy to mitigate radiation-related complications in clinical settings.

Abstract
PURPOSE The aim of this study was to determine the complications, incidence, and predictors of implant-based reconstruction failure (RF) among patients treated with mastectomy for breast cancer. METHODS We retrospectively reviewed 108 patients who underwent mastectomy, tissue expander, and implant-based breast reconstruction with or without radiation therapy (RT) at our institution (2000-2014). Descriptive statistics determined complication incidences, with major complications defined as any complications requiring surgical intervention or inpatient management. Chi square and Fisher's exact tests determined differences in RF incidences, defined as implant loss. Logistic regression analyses identified predictors of RF. RESULTS Median follow-up was 42.5 months. Sixty patients (55.6%) experienced major complications. Overall, 27 patients (25%) experienced RF. Incidences of RF were significantly increased in patients who had any major complication (43.3% vs. 2.1%; p < 0.0001), especially infection (61.3% vs. 10.4%; p < 0.0001), delayed wound healing (83.3% vs. 21.7%; p = 0.004), and implant exposure (80.0% vs. 19.4%; p = 0.0002). Receiving RT, but not timing of RT, significantly predicted RF [odds ratio (OR) 4.00, 95% confidence interval (CI) 1.11-14.47; p = 0.03]. On multivariable analysis, infection (OR 7.69, 95% CI 2.12-27.89; p = 0.002) and delayed wound healing (OR 17.86, 95% CI 1.59-200.48; p = 0.02) independently predicted for RF. Our newly developed classification tree, which includes stepwise assessment of major infection, delayed wound healing, implant exposure, age ≥ 50 years, and total number of lymph nodes removed ≥ 10, accurately predicted 74% of RF events and 75% of non-RF events. CONCLUSIONS Infection or delayed wound healing requiring surgical intervention or hospitalization and receipt of RT, but not radiation timing, were significant predictors of RF. Our classification tree demonstrated > 70% accuracy for stepwise prediction of RF.

Abstract
BACKGROUND Breast capsular contracture is a major problem following implant-based breast reconstruction, particularly in the setting of radiation therapy. Recent work has identified a fibrogenic fibroblast subpopulation characterized by CD26 surface marker expression. OBJECTIVES This work aimed to investigate the role of CD26-positive fibroblasts in the formation of breast implant capsules following radiation therapy. METHODS Breast capsule specimens were obtained from irradiated and nonirradiated breasts of 10 patients following bilateral mastectomy and unilateral irradiation at the time of expander-implant exchange, under institutional review board approval. Specimens were processed for hematoxylin and eosin staining as well as for immunohistochemistry and fluorescence activated cell sorting for CD26-positive fibroblasts. Expression of fibrotic genes and production of collagen were compared between CD26-positive, CD26-negative, and unsorted fibroblasts. RESULTS Capsule specimens from irradiated breast tissue were thicker and had greater CD26-postive cells on immunofluorescence imaging and on fluorescence activated cell sorting analysis than did capsule specimens from the nonirradiated breast. Compared with CD26-negative fibroblasts, CD26-positive fibroblasts produced more collagen and had increased expression of the profibrotic genes IL8, TGF-β1, COL1A1, and TIMP4. CONCLUSIONS CD26-positive fibroblasts were found in a significantly greater abundance in capsules of irradiated compared with nonirradiated breasts and demonstrated greater fibrotic potential. This fibrogenic fibroblast subpopulation may play an important role in the development of capsular contracture following irradiation, and its targeted depletion or moderation may represent a potential therapeutic option.

Abstract
BACKGROUND In immediate breast reconstruction, the plastic surgeon must strive to create an aesthetically pleasing result while minimizing complications. The latissimus dorsi (LD) myocutaneous flap has long been used a workhorse flap in breast reconstruction. Often times, it is used a salvage flap after other methods of breast reconstruction have failed. In this study, we review the use of this flap in conjunction with prosthetic devices, regardless of the need for adjuvant radiation, to determine the safety and efficacy of this approach as a primary method of reconstruction. METHODS A single surgeon practice with a standardized reconstructive algorithm was reviewed. This compromises a 2-stage approach involving the use of LD myocutaneous flaps and tissue expanders for immediate reconstruction after mastectomy, followed by exchange for implants at a secondary surgery. A retrospective chart review was performed on 201 patients (376 breast reconstructions) who met inclusion criteria. Patient demographics and outcomes were compared based on radiation status. The primary outcome, reconstructive success, was defined as no need for further autologous reconstruction beyond the 2-stage approach utilized. RESULTS Statistical analysis was performed on both patient demographics, complications, and reconstructive outcomes. Demographics were equivalent between the 2 groups. When analyzing complications and outcomes, there was no difference between nonradiated patients and radiated patients except when looking at reconstructive loss, which was 3.6% in the nonradiated group and 16.6% in the radiated group (P = 0.03). However, one third of the patients in the radiated group who had reconstructive losses were due to reasons not related to radiation therapy. Taking this into account, overall reconstructive success showed no statistical significance between the 2 groups. CONCLUSIONS The findings from this study show that immediate reconstruction with LD myocutaneous flaps in conjunction with prosthetic devices is a reliable and safe option, even in the setting of adjuvant radiation therapy, as the autologous tissue mitigates many sequelae of radiation therapy. Not only does this type of reconstruction provide an aesthetically pleasing result in 2 stages, but also has a favorable complication profile and success rate.

Abstract
This systematic review with meta-analysis addressed late locoregional complications associated with adjuvant radiotherapy (RT) in breast cancer. Among 2120 titles, ten comparative studies in patients undergoing surgery vs surgery and radiotherapy reporting complications were evaluated. RT was associated with an increased risk of capsular contracture and decreased the mobility of the upper limb. A borderline association of lymphedema risk using RT was noted in the random-effects model but was significant in the fixed-effects model.

Higher reconstruction failure and less patient-reported satisfaction after post mastectomy radiotherapy with immediate implant-based breast reconstruction compared to immediate autologous breast reconstruction. Breast Cancer 2019; 27:435-444.

Abstract
PURPOSE To improve shared decision making, clinical- and patient-reported outcomes between immediate implant-based and autologous breast reconstruction followed by postmastectomy radiotherapy (PMRT) were compared. METHODS All women with in situ and/or invasive breast cancer who underwent skin sparing mastectomy with immediate breast reconstruction (IBR) (autologous- or implant based, one- or two staged) followed by PMRT in the Utrecht region between 2012 and 2016 were selected from the Netherlands Cancer Registry, of which 112 (59%) agreed to participate. The primary outcome was reconstruction failure after the start of radiotherapy, and secondary outcomes were patient-reported outcomes measured with BREAST-Q. RESULTS 109 patients underwent skin-sparing mastectomy, of which 29 (27%) underwent immediate autologous reconstruction and 80 (73%) received immediate implant-based reconstruction. After PMRT, reconstruction failure occurred in 17 patients (21%) with implant-based reconstruction, while no failure was seen in the autologous group (p = 0.04). Mean patient-reported 'Satisfaction with Breasts' (50.9 vs. 63.7, p = 0.001) and 'Sexual Well-being' (46.0 vs. 55.5, p = 0.037) were lower after implant-based reconstruction compared to autologous reconstruction. Thirteen patients with autologous flaps underwent surgical cosmetic corrections compared to ten patients in the implant group (45 vs. 13%, p = 0.001). IBR and PMRT in this study resulted in a high rate of severe capsular contraction in implant-based reconstruction (16.9%) and fibrosis in autologous reconstruction (13.8%). CONCLUSIONS Patients treated with PMRT and one or two stage immediate implant-based reconstruction were at greater risk of developing reconstruction failure and were less satisfied when compared to one or two stage immediate autologous reconstruction. Since fairly high complication rates in both reconstruction methods after PMRT are observed, it raises the question whether immediate breast reconstruction should be considered at all when PMRT is indicated. Patients considering or potential candidates for IBR should be informed about the consequences of PMRT and especially when opting for autologous reconstruction one should possibly perform reconstruction in a secondary setting.

Abstract
Capsular contracture is a devastating complication that occurs in patients undergoing implant-based breast reconstruction. Ionizing radiation drives and exacerbates capsular contracture in part by activating cytokines, including transforming growth factor-beta (TGF-β). TGF-β promotes myofibroblast differentiation and proliferation, leading to excessive contractile scar formation. Therefore, targeting the TGF-β pathway may attenuate capsular contracture. METHODS A 20,000 small molecule library was screened for anti-TGF-β activity. Structurally diverse anti-TGF-β agents were identified and then tested on primary human capsular fibroblasts. Fibroblasts were irradiated or not, and then treated with both TGF-β and candidate molecules. Resulting cells were then analyzed for myofibroblast activity using myofibroblast markers including alpha-smooth muscle actin, collagen I, Thy1, and periostin, using Western Blot, quantitative real-time polymerase chain reaction, and immunofluorescence. RESULTS Human capsular fibroblasts treated with TGF-β showed a significant increase in alpha-smooth muscle actin, collagen I, and periostin levels (protein and/or mRNA). Interestingly, fibroblasts treated with latent TGF-β and 10 Gy radiation also showed significantly increased levels of myofibroblast markers. Cells that were treated with the novel small molecules showed a significant reduction in myofibroblast activation, even in the presence of radiation. CONCLUSIONS Several novel small molecules with anti-TGF-β activity can effectively prevent human capsular fibroblast to myofibroblast differentiation in vitro, even in the presence of radiation. These results highlight novel therapeutic options that may be utilized in the future to prevent radiation-induced capsular contracture.

Background Little is known with regard to patient-reported outcomes (PROs) in the setting of implant-based reconstruction (IBR) with post-mastectomy radiation therapy (PMRT). Methods We identified patients who underwent immediate IBR from a prospectively compiled database. The Breast Reconstruction Satisfaction Questionnaire (BRECON-31) was scored and compared between patients with and without PMRT. Results Sixty-four women met the study criteria. Forty-eight did not receive PMRT and 16 did. Nine women had an unanticipated indication for PMRT. The PMRT group was similar to the control group with regard to baseline characteristics (ie, age, marital status, body mass index, tobacco use, and comorbidities). However, treatment and oncologic characteristics (eg, diagnosis, tumour characteristics, systemic therapy use) differed. Of all complications, only capsular contracture rates differed (1.2% vs 13%; P = .01). Of the 9 subscales, 7 showed no difference in satisfaction between the groups. Radiated women scored lower in the arm concerns and breast appearance subscales. Scores were similar whether the indication for PMRT had been anticipated or not. Discussion Women with immediate IBR scored similarly to their nonradiated counterparts across 7 of 9 domains of satisfaction. Arm concerns and breast appearance scores are lower with PMRT, likely secondarily to more extensive nodal procedures in higher stage patients and to the side effect profile of radiotherapy. Our findings are in line with the few available studies using other PRO tools to evaluate the impact of PMRT on patient satisfaction and studies objectively measuring the effect of PMRT on arm morbidity and cosmetic outcomes.

Influence of Radiation Dose to Reconstructed Breast Following Mastectomy on Complication in Breast Cancer Patients Undergoing Two-Stage Prosthetic Breast Reconstruction. Front Oncol 2019; 9:243. [PMID: 31024845 PMCID: PMC6465567 DOI: 10.3389/fonc.2019.00243] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2018] [Accepted: 03/18/2019] [Indexed: 12/16/2022] Open
Abstract
Purpose: This study investigated the association between radiation dose and complication rate in patients who underwent breast reconstruction to understand the role of radiation hypofractionated regimen, boost radiation therapy (RT), and RT techniques. Methods: We retrospectively evaluated 75 patients treated with post-mastectomy adjuvant RT for breast cancer in the setting of two-stage prosthetic breast reconstruction. Near maximum radiation dose (Dmax) in the 2 or 0.03 cc of reconstructed breast or overlying breast skin was obtained from dose-volume histograms. Results: Post-RT complications occurred in 22.7% of patients. Receiver operating characteristic analysis showed that all near Dmax parameters were able to predict complication risk, which retained statistical significance after adjusting other variables (odds ratio 1.12 per Gy, 95% confidence interval 1.02–1.23) with positive dose-response relationship. In multiple linear regression model (R2 = 0.92), conventional fractionation (β = 11.7) and 16 fractions in 2.66 Gy regimen (β = 3.9) were the major determinants of near Dmax compared with 15 fractions in 2.66 Gy regimen, followed by utilization of boost RT (β = 3.2). The effect of bolus and dose inhomogeneity seemed minor (P > 0.05). The location of hot spot was not close to the high density metal area of the expander, but close to the surrounding areas of partially deflated expander bag. Conclusions: This study is the first to demonstrate a dose-response relationship between risk of complications and near Dmax, where hypofractionated regimen or boost RT can play an important role. Rigorous RT-quality assurance program and modification of dose constraints could be considered as a critically important component for ongoing trials of hypofractionation. Based on our findings, we initiated a multi-center retrospective study (KROG 18-04) and a prospective study (NCT03523078) to validate our findings.

Abstract
INTRODUCTION Capsular contracture (CC) is the most common complication of breast implantation, with an incidence of nearly 50% in patients undergoing breast reconstruction with subsequent radiotherapy. Although the move toward submuscular (SM) device placement led to a decreased incidence of CC, subcutaneous (SQ) implantation has seen a resurgence. The purpose of this study was to use a rodent model of breast reconstruction with smooth silicone implants and delayed radiotherapy to assess the occurrence of CC in SQ versus SM implantation. METHODS Custom 2 mL smooth round silicone implants were placed bilaterally into 12 female Sprague Dawley rats that were randomized into 4 groups of 3, with each group differing by implantation plane (SQ vs SM) and irradiation status (irradiated vs nonirradiated). Rats from the SQ group received implants bilaterally underlying the skin on the flank. Rats in the SM groups received implants bilaterally under the latissimus dorsi muscle. Irradiated rats received 20 Gy localized to each implant on postoperative day 10. One rat from each group was imaged with a micro-computed tomography scanner at baseline and at explant 3 months later, whereupon capsules from all rats were examined histologically. RESULTS Rats in the SQ group showed evidence of contracture on gross examination and greater evidence of morphologic disruption per micro-computed tomography scan. There was no evidence of contracture or morphologic disruption in either SM group. Mean ± SD capsule thickness was 39.0 ± 9.0 μm in the SQ versus 37.6 ± 9.8 μm in the SM nonirradiated groups and 43.9 ± 14.9 μm in the SQ versus 34.3 ± 8.3 μm in the SM irradiated groups (all P > 0.05). CONCLUSIONS In a rodent model of smooth silicone breast implantation and delayed radiotherapy, although there did not appear to be differences in capsule thickness regardless of device placement plane, SQ implants demonstrated gross evidence of CC. These data indicate that capsule thickness is only part of a larger pathogenetic picture, which should take into consideration the contribution from all peri-implant tissue.

Abstract
BACKGROUND Implant-based breast augmentation is one of the most frequently performed operations in plastic surgery worldwide, for aesthetic and reconstructive reasons. Capsular fibrosis is the most common long-term foreign body response after breast implant augmentation. OBJECTIVE To compare the occurrence of capsular contracture in aesthetic and reconstructive-cancer patients, including those patients who received radiotherapy prior to breast reconstruction with implants. METHODS We conducted a retrospective evaluation of 319 patients who underwent breast implant revision between Jan 2000 and Oct 2016. The patient group was comprised of 175 reconstructive-cancer patients and 144 patients who underwent operation for aesthetic reasons. The occurrence of capsular fibrosis, other complications and the time-period between implantation of breast implants and revision surgery (TP) was analyzed. RESULTS For all 319 patients the mean TP was 7.9 years (7.86±0.45). The most common complication in all revisions was capsular fibrosis (65.1% of all revisions). In aesthetic patients with capsular fibrosis the mean TP was 11.9 years (11.89±0.95, p < 0.001). This mean TP was significantly higher than the mean TP of 6.1 years (6.13±0.56, p < 0.001) in breast cancer patients with capsular fibrosis. Preoperatively irradiated cancer patients had a mean TP of 6.2 years (6.17±0.95), compared to a mean TP of 5.1 years (5.07±0.19, p = 0.051) in non-irradiated cancer patients, which was not significantly different. CONCLUSIONS We found that aesthetic patients exhibit a significantly higher mean TP compared to breast cancer patients, suggesting that reconstructive-cancer patients in general develop capsular fibrosis earlier. Despite the literature, we did not find a significant influence of preoperative radiotherapy on the occurrence of capsular fibrosis in reconstructive-cancer patients. Further clinical studies need to be conducted to identify methods to decrease the risk of developing capsular fibrosis.

Abstract
Background Capsular contracture remains one of the major complications after breast implantation surgery. The extent of capsular contraction is scored using the Baker scale. The aim of this study was to compare intra-individual Baker-I with Baker-IV capsules, and in particular the prevalence and histological properties of the inner capsule layer. Methods Twenty capsules from ten patients were included after bilateral explantation surgery due to unilateral capsular contracture (Baker-IV) after cosmetic augmentation with textured implants. All capsules underwent (immune-)histochemical analysis: haematoxylin–eosin (morphology), CD68 (macrophages), cytokeratin (epithelial cells) and vimentin (fibroblasts), and were visually scored for cell density and the presence of an inner layer and measured for thickness. Results Baker-IV (n = 10) capsules were significantly thicker compared to Baker-I (n = 10) capsules (P = 0.004). An inner layer was present in 8 Baker-I capsules. All Baker-I capsules were vimentin and CD68-positive and cytokeratin-negative. Positive vimentin was seen throughout the inner layer, and CD-68 staining was observed adjacent to the intermediate capsule layer. In contrast, only 2 Baker-IV capsules had an inner layer, of which only 1 showed the same profile as Baker-I capsules (P = 0.016). No cytokeratin positivity was seen in any capsule. In Baker-IV capsules, outer layers showed more positivity for both vimentin and CD68. Conclusion The inner layer is morphologically consistent with synovial metaplasia and is more prevalent in healthy, uncontracted Baker-I capsules. This inverse relation between the presence of the inner layer and higher Baker classification or pathological contracture could indicate a protective role of the inner layer against capsular contracture formation.

Abstract
BACKGROUND Immediate prosthetic breast reconstruction produces a satisfactory aesthetic result with high levels of patient satisfaction. However, with the broader indication for postmastectomy adjuvant radiation therapy, many patients are advised against immediate breast reconstruction because of concerns of implant loss and infection, particularly as most patients also require chemotherapy. This retrospective cohort study examines outcomes for patients who underwent immediate two-stage prosthetic breast reconstruction after mastectomy with or without adjuvant chemotherapy or radiotherapy. METHODS Between 1998 and 2010, 452 patients undergoing immediate two-stage prosthetic breast reconstruction involving a total of 562 breasts were included in this study. Stage 1 was defined as insertion of the temporary expander, and stage 2 was defined as insertion of the final silicone implant. Postoperative adjuvant radiotherapy was recommended with a tissue expander in situ for 114 patients. Complications, including loss of prosthesis, seroma, and infection, were recorded and analyzed. Cosmetic result was assessed using a four-point scale. RESULTS Postoperative prosthesis loss was 2.7 percent, 5.3 percent for patients undergoing adjuvant chemotherapy and increasing to 11.3 percent for patients receiving chemotherapy plus radiotherapy. Chemotherapy and radiotherapy independently were the main, statistically significant risk factors for expander or implant loss [incidence rate ratio, 13.85 (p = 0.012) and 2.23 (p = 0.027), respectively]. Prosthesis loss for patients undergoing combination chemotherapy plus radiotherapy was also significant [incidence rate ratio, 4.791 (p < 0.001)]. CONCLUSIONS These findings serve to better inform patients on risk in weighing treatment options. Postmastectomy radiation therapy doubles the risk of prosthesis loss over and above adjuvant chemotherapy but is an acceptable option following immediate two-stage prosthetic breast reconstruction in a multidisciplinary setting.

Abstract
The purpose of this study was to model the metallic port in breast tissue expanders and to improve the accuracy of dose calculations in a commercial photon treatment planning system (TPS). The density of the model was determined by comparing TPS calculations and ion chamber (IC) measurements. The model was further validated and compared with two widely used clinical models by using a simplified anthropomorphic phantom and thermoluminescent dosimeters (TLD) measurements. Dose perturbations and target coverage for a single postmastectomy radiotherapy (PMRT) patient were also evaluated. The dimensions of the metallic port model were determined to be 1.75 cm in diameter and 5 mm in thickness. The density of the port was adjusted to be 7.5 g/cm3 which minimized the differences between IC measurements and TPS calculations. Using the simplified anthropomorphic phantom, we found the TPS calculated point doses based on the new model were in agreement with TLD measurements within 5.0% and were more accurate than doses calculated based on the clinical models. Based on the photon treatment plans for a real patient, we found that the metallic port has a negligible dosimetric impact on chest wall, while the port introduced significant dose shadow in skin area. The current clinical port models either overestimate or underestimate the attenuation from the metallic port, and the dose perturbation depends on the plan and the model in a complex way. TPS calculations based on our model of the metallic port showed good agreement with measurements for all cases. This new model could improve the accuracy of dose calculations for PMRT patients who have temporary tissue expanders implanted during radiotherapy and could potentially reduce the risk of complications after the treatment.

Abstract
The aim of this study was to evaluate the dosimetry and toxicity of hypofractionation in postmastectomy radiotherapy (PMRT) with intensity-modulated radiotherapy (IMRT) in breast cancer (BC) patients. Stage II-III BC patients with implant-based immediate breast reconstruction received PMRT to the chest wall (CW) and to the infra/supraclavicular nodal region (NR) using a 15-fraction schedule (2.67 Gy/fraction) and helical IMRT (Tomotherapy® System, Accuray Incorporated, Sunnyvale, CA). A score was assigned to each treatment plan in terms of planning target volume (PTV) coverage of CW and NR and the sparing of the organs at risk (OARs). The total score for each plan was calculated. Toxicity was prospectively assessed according to validated scales. Data from 120 consecutive patients treated in the period 2012-2015 were analysed with a median follow-up from the end of radiotherapy of 13.2 months (range 0.0-35 months). 70.8% (85/120) of the plans had high total scores as a result of an optimal coverage of both CW and RN and optimal sparing of all OARs. The maximum acute toxicity was of grade 2 in 36.7% of the cases. Early late toxicity was mild in the majority of cases. In the study population, helical tomotherapy-based IMRT produced optimal treatment plans in most cases. Acute and late toxicity was mild/moderate. Hypofractionated helical IMRT appears to be safe and feasible in the moderate term for PMRT.

Abstract
OBJECTIVE The controversy remains as to whether immediate prosthetic breast reconstruction with postmastectomy radiation therapy (PMRT) is associated with acceptable complications and aesthetic outcomes. The aim of this meta-analysis was to provide a pooled analysis of comparative clinical studies that evaluated breast cancer patients who were treated with a mastectomy and an immediate prosthetic breast reconstruction to compare the complications and satisfaction of those who underwent or did not undergo PMRT. METHODS According to the recommendations of the Cochrane Collaboration, we established a rigorous study protocol. We performed a systematic electronic search of the PubMed and Embase databases to identify articles for inclusion in our meta-analysis. Reconstruction failure, overall complications, capsular contracture, and patient satisfaction were analyzed individually. RESULTS Fifteen controlled trials were included, comprising 5314 patients (1069 PMRT vs 4245 non-PMRT). Primary outcomes revealed a statistically significant increase in overall complications [odds ratio (OR) 3.45; 95% confidence interval (95% CI) 2.62-4.54; P < .00001], reconstruction failure (OR: 2.59; 95% CI 1.46-4.62; P = .001), and capsular contracture (OR: 5.26, 95% CI: 2.73-10.13, P < .00001) after receiving PMRT. CONCLUSION Our review found that PMRT for patients who underwent immediate implant-based breast reconstruction led to higher risks of reconstruction failure, overall complications, and capsular contracture. However, it is still the standard adjuvant therapy for mastectomy patients who have opted for immediate implant-based breast reconstruction.

Abstract
BACKGROUND Breast reconstruction is an essential component in the treatment of breast cancer. Postoperative complications after breast reconstruction are common and affect patient satisfaction. Determining independent risk factors using patient characteristics could be advantageous for patient assessment and counseling. METHODS We retrospectively enrolled 623 consecutive patients who underwent reconstruction with a deep inferior epigastric perforator flap (DIEP), latissimus dorsi flap (LD), lateral thoracodorsal flap (LTDF), or tissue expander with a secondary implant (EXP) in this study. Information on demographic and perioperative factors was collected, as well as information on all postoperative complications. Logistic regression was used to analyze associations between possible patient-related risk factors and postoperative complications. RESULTS Smoking was associated with the highest number of early overall complications [odds ratio (OR) 2.05, 95% confidence interval (CI) 1.25-3.37, P=0.0005], followed by body mass index (BMI) (OR 1.07, 95% CI 1.01-1.13, P=0.017). High BMI was associated with the highest number of late overall postoperative complications (OR 1.06, 95% CI 1.00-1.11, P=0.042), followed by history of radiotherapy (OR 1.66, 95% CI 1.01-2.74, P=0.046). When the risk factors were combined, the risk for postoperative complications rose exponentially. CONCLUSIONS Our results provide evidence that patients should cease smoking and overweight patients should lose weight before undergoing breast reconstruction. Additionally, if the patient has received radiotherapy, the reconstruction method should be carefully chosen. High BMI, history of radiotherapy, and smoking are independent risk factors for many types of both early and late postoperative complications in breast reconstructive surgery. Combining these risk factors multiplies the risk of postoperative complications.

The Effect of the Timing of Radiotherapy on Clinical and Patient-Reported Outcomes After Latissimus Dorsi Breast Reconstruction: A 10-Year Study. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2017; 5:e1348. [PMID: 28740767 PMCID: PMC5505828 DOI: 10.1097/gox.0000000000001348] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2016] [Accepted: 04/07/2017] [Indexed: 11/26/2022]
Abstract
Background: Breast reconstruction (BR) is considered to be adversely affected by radiotherapy (RT), particularly when an implant is used. The aim of this study was to compare clinical and patient-reported outcomes after expander-assisted latissimus dorsi breast reconstruction depending on the timing of RT. Methods: Patients undergoing BR over a 10-year period (follow-up mean, 56 [14–134] months) were divided into 3 groups. Group 1, RT after mastectomy and BR, Group 2, RT before mastectomy and BR, and Group 3, RT after mastectomy but before BR. The primary endpoints were early and late surgical interventions. Validated questionnaires were circulated to all study patients and matched controls. Results: Three hundred thirteen patients underwent 389 BRs. One hundred eighteen patients received RT, of which 65 had undergone expander-assisted latissimus dorsi breast reconstruction. Both use and timing of RT influenced clinical outcomes. Overall, use of RT resulted in a 3-fold increase in complications (P = 0.003). Postreconstruction RT resulted in more than double the number of complications compared with prereconstruction RT (P = 0.008) and delaying BR until after mastectomy and RT reduced complications to levels observed in control patients (P = nonsignificant). Complications were halved in patients undergoing autologous LD reconstruction (P = 0.0001). Patient-reported outcomes were similar for emotional well-being, satisfaction, and shoulder symptoms, although a nonsignificant increase in chronic breast symptoms was reported by the RT group. Conclusion: The timing and type of LD reconstruction chosen by patients receiving RT has a significant impact on the risk of subsequent complications and unplanned interventions but has little impact on longer term patient well-being or satisfaction.

Abstract
The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 45-year-old premenopausal woman presented with multifocal cancer in the right breast, with lesions at 1:00 and 4:00, the largest measuring approximately 3 cm on exam, and multiple palpable right axillary lymph nodes. A core biopsy confirmed invasive ductal carcinoma, grade 2 of 3, that was estrogen receptor positive, progesterone receptor positive, and HER2 negative. Fine needle aspiration of a right axillary node confirmed metastatic carcinoma. A positron emission tomography (PET)/ computed tomography done before starting chemotherapy demonstrated an absence of metastatic disease with expected avidity in two separate breast masses and multiple conglomerated 1-2 cm level I and II axillary lymph nodes. She received neoadjuvant chemotherapy with doxorubicin plus cyclophosphamide, followed by paclitaxel, and had a complete clinical response with resolution of the breast and axillary masses on exam. A repeat PET/computed tomography demonstrated reduced size of the breast and axillary disease, and no significant residual PET avidity. Her breast surgeon recommended a right mastectomy with axillary node dissection. As part of her multidisciplinary treatment plan, she consulted with two plastic surgeons to discuss reconstruction options. Plastic Surgeon A advised placement of an implant at the time of mastectomy while Surgeon B contrasted the pros and cons of an autologous transverse rectus abdominis muscle flap reconstruction with an implant based reconstruction. Surgeon B believed that autologous reconstruction would yield the best long-term cosmetic outcome. Before making her surgery decision, the patient consulted with a radiation oncologist to discuss the effect radiation may have on her reconstruction outcome.

Abstract
BACKGROUND AND PURPOSE Radiation oncology guidelines favour hypofractionated whole-breast radiotherapy (HWBRT) over more conventional schemes in the conservative treatment of breast cancer, but its adoption still varies in clinical practice. This study assessed the patterns of HWBRT adoption in Catalonia (Spain). MATERIAL AND METHODS We used a mixed-methods approach based on an explanatory sequential design, first collecting and analysing quantitative data on HWBRT use (>2.5Gy per fraction) in 11 public radiotherapy centres (2005-2015) and then performing 25 semi-structured interviews with all department heads and reference radiation oncologist/s. RESULTS Of the 34,859 patients fulfiling the study criteria over the study period, just 12% were hypofractionated, reaching a percentage of 29% in 2015 (p<0.001). Our analysis showed a narrowing age gap between patients receiving conventional fractionation and hypofractionation in centres leading adoption. However, there were important differences in clinicians' interpretation of evidence (e.g. regarding the perceived risk of long-term toxicity) and selection of patients for specific indications, both within and between departments. CONCLUSIONS Differences observed in the rate of adoption of HWBRT could not be tackled only using a rational, evidence-based approach. Factors related to the management of radiotherapy departments play a major role in the diffusion of therapeutic strategies.

Abstract
BACKGROUND Immediate breast reconstruction (IBR) after mastectomy has shown to be oncologically safe and to improve quality of life in breast cancer patients. However, most women undergoing mastectomy do not undergo IBR. In this study, we aim to identify breast surgeon-related factors in considering IBR and factors affecting patients' decision to choose for IBR. METHODS Retrospective analysis of the records of breast cancer patients who underwent mastectomy with or without IBR between 2010 and 2013. We documented all information whether or not a patient underwent IBR after mastectomy. RESULTS Of 437 patients, 97 (22.2%) underwent IBR, 89.8% of which received tissue expanders. Patient who did not undergo IBR had a higher age (62.2 versus 51.9 years, P<0.001) and higher body mass index (BMI) (27.0 versus 24.3, P<0.001). Hundred three patients declined IBR, mainly because considering reconstruction as too much trouble. In 128 cases the breast surgeon did not offer IBR, mostly because of the predicted need for post mastectomy radiation. Approximately 11% of the patients were not informed about IBR. CONCLUSIONS Anticipated radiation therapy, higher age and higher BMI were important breast surgeon-related factors in refraining from IBR. Almost one third of all patients declined IBR. In almost 10% of all patients, IBR was not discussed.

Abstract
BACKGROUND Capsular contracture (CC) is a major complication of breast surgery with smooth and textured implants. Polyurethane (PU) foam-coated breast implants were developed to decrease the incidence of CC. OBJECTIVES The authors determined the incidence of CC following 2-stage breast reconstruction using PU foam-covered implants, with and without radiation therapy. METHODS The records of 92 patients who received 115 PU implants were retrospectively reviewed. The rates of CC over time were compared for irradiated and nonirradiated groups with a Kaplan-Meier analysis and log-rank test. CC rates also were analyzed with respect to age. RESULTS The median follow-up time for patients was 103.3 months. Nine patients experienced unilateral Baker grade III or IV fibrous CC, including 6 patients from the irradiated group and 3 patients from the nonirradiated group. The overall cumulative incidence of CC at 9 years was 8.1%. In the irradiated and nonirradiated groups, the 9-year cumulative incidence was 10.7% and 5.5%, respectively. CC occurred within 3 years in the irradiated group and within 7 years in the nonirradiated group. The incidence of CC appeared to be higher among younger patients. CONCLUSIONS Radiation therapy increases the risk of high-grade CC with textured or smooth implants. PU implants are associated with a much lower cumulative incidence of CC following 2-stage breast reconstruction, even when radiotherapy is performed. LEVEL OF EVIDENCE 3.

Abstract
Aims. This paper describes a UK survey of the choice of radiotherapy regime for the reconstructed chest wall in breast cancer patients. Questions focused on which fractionation regime consultants choose, their reasons for this, whether the type of reconstruction influences their choice, and whether bolus is used in patients who have undergone immediate reconstructive surgery. Materials and Methods. Between July 2014 and July 2015 a survey was sent by email to UK consultant radiation oncologists treating breast cancer. Results. The response rate was 73%. 67% of respondents use 40 Gray (Gy) in 15 fractions, with 22% using 50 Gy in 25 fractions and 7% using other regimes. For 90% of consultants the type of reconstruction did not influence their decision regarding choice of fractionation. 83% of respondents do not usually use a bolus for chest wall radiotherapy in patients who have had immediate reconstructive surgery. Conclusions. This survey illustrates there is variation in practice in the management of patients with breast cancer who have undergone immediate reconstructive surgery in the UK. There is a need for further research to determine which fractionation regime is optimal, whether the type of surgery is relevant, and whether bolus should be added.

Abstract
PURPOSE Capsular contracture (CC) is a serious complication in patients receiving implant-based reconstruction for breast cancer. Currently, no objective methods are available for assessing CC. The goal of the present study was to identify image-based surrogates of CC using magnetic resonance imaging (MRI). METHODS AND MATERIALS We analyzed a retrospective data set of 50 patients who had undergone both a diagnostic MRI scan and a plastic surgeon's evaluation of the CC score (Baker's score) within a 6-month period after mastectomy and reconstructive surgery. The MRI scans were assessed for morphologic shape features of the implant and histogram features of the pectoralis muscle. The shape features, such as roundness, eccentricity, solidity, extent, and ratio length for the implant, were compared with the Baker score. For the pectoralis muscle, the muscle width and median, skewness, and kurtosis of the intensity were compared with the Baker score. Univariate analysis (UVA) using a Wilcoxon rank-sum test and multivariate analysis with the least absolute shrinkage and selection operator logistic regression was performed to determine significant differences in these features between the patient groups categorized according to their Baker's scores. RESULTS UVA showed statistically significant differences between grade 1 and grade ≥2 for morphologic shape features and histogram features, except for volume and skewness. Only eccentricity, ratio length, and volume were borderline significant in differentiating grade ≤2 and grade ≥3. Features with P<.1 on UVA were used in the multivariate least absolute shrinkage and selection operator logistic regression analysis. Multivariate analysis showed a good level of predictive power for grade 1 versus grade ≥2 CC (area under the receiver operating characteristic curve 0.78, sensitivity 0.78, and specificity 0.82) and for grade ≤2 versus grade ≥3 CC (area under the receiver operating characteristic curve 0.75, sensitivity 0.75, and specificity 0.79). CONCLUSIONS The morphologic shape features described on MR images were associated with the severity of CC. MRI has the potential to further improve the diagnostic ability of the Baker score in breast cancer patients who undergo implant reconstruction.
