Abstract
PURPOSE To test the efficacy and safety of cross-linked hyaluronic acid application for filling buttocks and cellulite depressions and its permanence over time. METHODS For a period of a year, 25 patients were applied redensified cross-linked hyaluronic acid in the gluteal area. These patients were all 23-45-year-old women with little fat to be removed. The product used is composed of hyaluronic acid with high cross-linking and redensification which allows it to maintain shape and durability over time. All patients underwent tumescent anesthesia with neuroleptic sedation in the operating room. The procedure was regarded as minimal (container, sterile gloves, and surgical field). The amount applied for gluteal augmentation varied from 50 to 100 ml per application area and according to the patient's needs. For the filling of cellulite depressions, the application was up to 3 cc per depression and up to a total of 40 ml. The maximum volume used per patient in the buttocks did not exceed 200 ml, and it did not exceed 40 ml in cellulite depressions. RESULTS A group of patients was treated in the upper and middle third of the buttocks in superficial and deep subcutaneous layers and in cellulite depressions. Very good results have been obtained without any major complications. CONCLUSIONS The use of redensified cross-linked hyaluronic acid of non-animal origin is therefore an option for gluteal augmentation and cellulite depressions. Although the product degrades over time, after 12 months, 44% of treated patients rated their results as highly or very much improved, 36% as improved, 16% rated the improvement as poor, and one patient (4%) was dissatisfied.

Abstract
BACKGROUND Autologous fat grafting has become a vital component of breast reconstruction. However, concerns remain regarding the safety of fat grafting after oncological resection and breast reconstruction. The purpose of the study was to evaluate the association of fat grafting after breast reconstruction with metastasis and death in breast cancer patients. METHODS A retrospective, population-based cohort study was conducted using deidentified claims data from 2001 to 2018 and included privately insured patients with breast cancer who underwent breast reconstruction after surgical resection. Breast reconstruction patients who underwent fat grafting were compared with those not undergoing fat grafting, evaluating metastasis and death up to 15 years after reconstruction. One-to-one propensity score matching was used to account for selection bias on patient risk factors comparing those with and without fat grafting. RESULTS A total of 4709 patients were identified who underwent breast reconstruction after lumpectomy or mastectomy, of which 368 subsequently underwent fat grafting. In the propensity score-matched patients, fat grafting was not associated with an increased risk of lymph node metastasis (9.7% fat-grafted vs 11.4% in non-fat-grafted, P = 0.47) or distant metastasis (9.1% fat-grafted vs 10.5% in non-fat-grafted, P = 0.53). There was no increased risk of all-cause mortality after fat grafting for breast reconstruction (3.9% fat-grafted vs 6.6% non-fat-grafted, P = 0.10). CONCLUSIONS Among breast cancer patients who subsequently underwent fat grafting, compared with no fat grafting, no significant increase was observed in distant metastasis or all-cause mortality. These findings suggest that autologous fat grafting after oncologic resection and reconstruction was not associated with an increased risk of future metastasis or death.

Abstract
BACKGROUND Lipomodelling (LM) is an increasingly used technique to reconstruct or correct an aesthetic defect linked to a loss of substance. In France, the Haute Autorité de santé (HAS) published recommendations in 2015 and 2020 concerning the conditions of use of LM on the treated and contralateral breast. These appear to be inconsistently followed. METHODS Twelve members of the Senology Commission of the Collège national des gynécologues-obstétriciens français (French College of Gynecologists and Obstetricians) reviewed the carcinological safety of LM and the clinical and radiological follow-up of patients after breast cancer surgery, based on French and international recommendations and a review of the literature. The bibliographic search was conducted via Medline from 2015 to 2022, selecting articles in French and English and applying PRISMA guidelines. RESULTS A total of 14 studies on the oncological safety of LM, 5 studies on follow-up and 7 guidelines were retained. The 14 studies (6 retrospective, 2 prospective and 6 meta-analyses) had heterogeneous inclusion criteria and variable follow-up, ranging from 38 to 120 months. Most have shown no increased risk of locoregional or distant recurrence after LM. A retrospective case-control study (464 LMs and 3100 controls) showed, in patients who had no recurrence at 80 months, a subsequent reduction in recurrence-free survival after LM in cases of luminal A cancer, highlighting the number of lost to follow-up (more than 2/3 of luminal A cancers). About follow-up after LM, the 5 series showed the high frequency after LM of clinical mass and radiological images (in ¼ of cases), most often corresponding to cytosteatonecrosis. Most of the guidelines highlighted the uncertainties concerning oncological safety of LM, due to the lack of prospective data and long-term follow-up. DISCUSSION AND PERSPECTIVES The members of the Senology Commission agree with the conclusions of the HAS working group, in particular by advising against LM "without cautionary periods", excessively, or in cases of high risk of relapse, and recommend clear, detailed information to patients before undergoing LM, and the need for postoperative follow-up. The creation of a national registry could address most questions regarding both the oncological safety of this procedure and the modalities of patient follow-up.

Abstract
BACKGROUND Autologous fat grafting (AFG) is often used to reconstruct defects after breast conservation therapy (BCT). However, concerns exist about the possibility of AFG-related recurrence or metastasis. This study aims to evaluate the literature to evaluate oncologic outcomes in patients undergoing AFG at the time of BCT. METHODS A systematic review of articles related to AFG based reconstruction at the time of BCT from 1970 to 2021 was performed via PubMed. Patients were grouped based on the presence or lack of AFG usage at the time of BCT, and oncologic outcomes and complications were compared. RESULTS Of the 146 articles identified, 15 were included. Nine hundred patients underwent BCT alone and 1063 patients underwent BCT with AFG patients. Similar average follow-up time was observed between the groups, 58.7 months (BCT only) and 55.2 months (BCT with AFG). On pooled analysis, no difference was identified in local recurrence 4.8% (43 patients) of the BCT group and 3% (32 patients) in the AFG group (P = 0.8), metastasis 4.8% (43 patients) of the BCT group and 6.9% (73 patients) in the AFG group (P = 0.3), or fat necrosis (P = 0.44). Meta-analysis additionally did not identify any statistically significant odds ratios between the BCT only group and BCT with AFG group when evaluated for total recurrence, local recurrence, metastasis or fat necrosis. CONCLUSIONS The results show no significant difference in cancer recurrence or metastasis in the BCT only group versus BCT and AFG, showing that fat grafting has safe outcomes.

Abstract
UNLABELLED Autologous fat grafting (FG) is increasingly used as an adjunctive reconstruction technique to augment volume, achieve symmetry, and improve contour deformities. This study aims to characterize the oncologic and surgical safety of FG in women undergoing autologous breast reconstruction (ABR) or implant-based reconstruction (IBR). METHODS A retrospective chart review was performed for all patients undergoing FG at a multi-site single health system between 2015 to 2018. A total of 228 eligible breasts from 155 patients were identified using Current Procedural Terminology codes. Patients were divided by reconstructive technique. Bivariate analyses compared baseline characteristics and post-FG outcomes. RESULTS Mean age for patients undergoing ABR (129 breasts) was 52.8 years compared to 48.6 years for those undergoing IBR (99 breasts; P = 0.002). A heavier volume of fat was grafted per ABR breast (143.8mL) than per IBR breast (102.2mL; P = 0.002). Forty-seven (20.6%) breasts required FG revision, more frequently in ABR breasts (31.0%) than IBR breasts (7.1%; P < 0.001). Following FG, 17.5% of patients experienced a palpable mass, and 18.9% of breasts underwent nonroutine diagnostics or procedures, with no difference between ABR and IBR groups. Most biopsies noted benign findings such as fat necrosis (2.2%) or a benign mass (0.9%), with recurrence only noted in two patients (0.9%). Mean follow-up was 20.4 months. CONCLUSION FG is a safe, surgically simple procedure more commonly performed in ABR breasts. FG use in ABR and IBR breasts is oncologically safe, with no impairment in breast surveillance and low rates of locoregional recurrence, but possibly increased incidence of nonroutine imaging and biopsies.

Abstract
BACKGROUND The American Society of Plastic Surgeons and The Plastic Surgery Foundation launched GRAFT, the General Registry of Autologous Fat Transfer, in October of 2015. This web-accessible registry addresses the need for prospective and systematic data collection, to determine the rates of unfavorable outcomes (complications) of fat grafting. Understanding and avoiding the factors that lead to complications can help establish safe practices for fat grafting. METHODS Data collected between October of 2015 and November of 2019 were summarized for age, sex, indications, processing techniques, and fat graft volume. Rates of complications for fat grafting to various anatomical areas were calculated. RESULTS The General Registry of Autologous Fat Transfer collected data on 7052 fat grafting procedures from 247 plastic surgery practices. The mean age of the patients in the registry was 51 years (range, 1 to 89 years), 94 percent were female, and 64 percent of the procedures were for aesthetic indications. Whereas the overall complication rate was low (5.01 percent), the complication rates for fat grafting to the breast and buttocks (7.29 percent and 4.19 percent, respectively) were higher than those for face and other areas (1.94 percent and 2.86 percent, respectively). Oil cysts (2.68 percent) and infections (1.64 percent) were the most common complications of breast fat grafting, whereas seroma (1.84 percent) and palpable mass (1.33 percent) were most common for fat grafting to buttocks. Palpable mass (0.54 percent) and infections (0.54 percent) were most common for fat grafting to face. CONCLUSIONS The General Registry of Autologous Fat Transfer provides a valuable tool for prospective tracking of fat grafting techniques and complications. Data collected in the registry show low rates of complications for all recipient areas treated with fat grafting. CLINICAL RELEVANCE STATEMENT GRAFT collects real world data on complications of autologous fat grafting procedures. The data collected over 4 years shows low rates of complications for fat grafting. The benchmarking tools available in GRAFT can help enhance techniques and safety of fat grafting. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Abstract
Background Lipofilling techniques are widespread in clinical practice as a complement to breast reconstruction, despite posing some risk. Punctual implant rupture following a fat transfer is one of the possible complications, which has not been properly reported yet and is probably being underdiagnosed. The aim of this paper is to report key facts for appropriate diagnosis of this clinical chart. Case Report We present the case of a 47-year-old woman with a bilateral prosthetic breast reconstruction who was treated with autologous fat graft for upper pole enhancing and scar improvement. The patient developed an early unilateral breast capsular contracture after the fat graft procedure, with normal radiological exploration. Surgical findings showed intraprosthetic fat deposits and a punctual implant rupture. Conclusions Punctual breast implant rupture is a possible complication of lipofilling that is usually not suspected at first consultation and might be underdiagnosed based on radiological findings, so investigating clinical signs should necessarily be a prerequisite to diagnosis.

Abstract
INTRODUCTION Autologous fat grafting (AFG) is a promising breast reconstruction technique, following surgery. However, fat necrosis after AFG can cause palpable nodules, inducing anxiety and prompting additional investigations. We aimed to determine the occurrence rate and to identify the risk factors of palpable nodules in breast cancer patients prompting complementary explorations. MATERIALS AND METHODS We retrospectively reviewed the computerized files of consecutive breast cancer patients who underwent AFG after mastectomy or breast conservative treatment (BCT) at our center from January 2013 to December 2016. We collected data regarding palpable nodule incidences and suspicious breast imaging findings that led to additional explorations. RESULTS Of the 252 patients reviewed, 222 (88%) underwent AFG for breast reconstruction, while 30 (12%) underwent AFG for correction of defects after BCT. The follow-up period ranged from 0 to 74 months (median: 27 months), and 201 patients had follow-ups beyond 1 year. Of the 252 patients, 66 (26.2%) underwent at least one control imaging and 24 (10%) underwent a biopsy, including 6 (2.4%) locoregional recurrence. Sixty patients (24%) were diagnosed with nodules during follow-ups. Among them, 52 (87%) patients had additional imaging, and 17 patients (28%) had a biopsy, including 82% benign histology. Patients with BCT had significantly more palpable nodules at 1 year than patients who underwent total mastectomy (odds ratio = 2.50, 95% confidence interval: 1.04. 6.03, p = 0.04). CONCLUSION This study underlines the importance of preoperative patient information. This intervention and its follow-up should be reserved for experienced teams to limit unnecessary additional explorations.

Abstract
Fat grafting is a well‐established method in plastic surgery. Despite many technical advances, standardised recommendations for the use of prophylactic antibiotics in fat grafting are not available. This retrospective multicentre study aims to analyse the use of prophylactic antibiotics in fat grafting and to compare complication rates for different protocols. A retrospective medical chart review of 340 patients treated with fat grafting of the breast from January 2007 to March 2019 was performed in three plastic surgery centres. Complications, outcomes, and antibiotic regimes were analysed. The Clavien‐Dindo classification was applied. All patients received perioperative antibiotic prophylaxis: 33.8% (n = 115) were treated with a single shot (group 1), 66.2% (n = 225) received a prolonged antibiotic scheme (group 2). There was no significant difference in the number of sessions (P = .475). The overall complication rate was 21.6% (n = 75), including graft resorption, fat necrosis, infection, and wound healing problems. Complication rates were not significantly different between groups. Risk factors for elevated complication rates in this specific patient group are smoking, chemotherapy, and irradiation therapy. The complication rate for lipografting of the breast is low, and it is not correlated to the antibiotic protocol. The use of prolonged prophylactic antibiotics does not lower the complication rate.

Abstract
Autologous fat grafting, first described in the 1890s, has since undergone many modifications to optimize safety and efficacy. These changes have resulted in the technique that we now consider standard of care, one that is applied to reconstruction and cosmetic enhancement of the breast and the face both independently and in conjunction with surgical treatment. There is a growing body of evidence that this application has positive outcomes for patient satisfaction, surgeon satisfaction, and overall aesthetic appearance. This article summarizes the body of literature regarding these outcomes, reviews complications of fat grafting in the face and breast, and discusses controversies including radiologic imaging changes and longevity of grafting. Level of Evidence: 4.

Int J Mol Sci 2021; 22:ijms22073737. [PMID: 33916703 PMCID: PMC8038405 DOI: 10.3390/ijms22073737] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 03/30/2021] [Accepted: 03/31/2021] [Indexed: 02/08/2023] Open
Abstract
Lipofilling (LF) is a largely employed technique in reconstructive and esthetic breast surgery. Over the years, it has demonstrated to be extremely useful for treatment of soft tissue defects after demolitive or conservative breast cancer surgery and different procedures have been developed to improve the survival of transplanted fat graft. The regenerative potential of LF is attributed to the multipotent stem cells found in large quantity in adipose tissue. However, a growing body of pre-clinical evidence shows that adipocytes and adipose-derived stromal cells may have pro-tumorigenic potential. Despite no clear indication from clinical studies has demonstrated an increased risk of cancer recurrence upon LF, these observations challenge the oncologic safety of the procedure. This review aims to provide an updated overview of both the clinical and the pre-clinical indications to the suitability and safety of LF in breast oncological surgery. Cellular and molecular players in the crosstalk between adipose tissue and cancer are described, and heterogeneous contradictory results are discussed, highlighting that important issues still remain to be solved to get a clear understanding of LF safety in breast cancer patients.

Abstract
BACKGROUND Patients who are suffering from invasive breast cancer may require post-mastectomy radiation therapy (PMRT). PMRT improves outcomes in breast cancer patients in terms of locoregional recurrence. Preliminary studies indicate that fat injections reduce post-radiation damage of soft tissue and implants. OBJECTIVES The aim of this study was to demonstrate the safety and effectiveness of prophylactic fat injections on radiated implanted breasts. METHODS The authors randomly assigned 60 female patients to either Group A or B. Group A patients received 3 breast fat injections, according to Coleman's technique, after radiotherapy and before expander removal with definitive implant insertion. Group B patients underwent surgery without lipofilling. At each surgical operation, skin biopsies were performed in a specific breast area to evaluate adipose tissue thickness, and a statistical analysis of the thickness variations was performed with the Wilcoxon's sum test. Disability was assessed according to the Late Effects of Normal Tissues-Subjective Objective Management Analytic scale. RESULTS The study demonstrates a qualitative and quantitative improvement about tissues after fat injection. This is highlighted by the significant increase in thickness after lipofilling. CONCLUSIONS The study, which is based on both clinical and histological findings and is supported by the comparison of a control group with a 1-year follow-up, demonstrates that fat injections reduce tissue radio damage, improving reconstructive surgery outcomes and quality of life.

Abstract
BACKGROUND The purpose of this study was to compare the commonly used fat grafting techniques-Telfa rolling and a closed washing system-in breast reconstruction patients. METHODS Consecutive patients undergoing fat grafting were retrospectively reviewed and grouped by technique. Patients with less than 180 days of follow-up were excluded. Demographics, operative details, and complications were compared using univariate analysis with significance set at p < 0.05. RESULTS Between January of 2013 and September of 2017, 186 women underwent a total of 319 fat grafting procedures. There was no difference in demographics, number of procedures performed, volume of fat grafted, and number of days after reconstruction that fat grafting was performed between groups (p > 0.05). Telfa rolling patients had longer operative times for second fat grafting procedures (implant exchange often completed prior) [100.0 minutes (range, 60.0 to 150.0 minutes) versus 79.0 minutes (range, 64.0 to 94.0 minutes); p = 0.03]. Telfa rolling breasts had more palpable masses requiring imaging (26.0 percent versus 14.4 percent; p = 0.01) and an increased incidence of fat necrosis (20.6 percent versus 8.0 percent; p < 0.01). The closed washing system was found to be an independent predictor of decreased rates of imaging-confirmed fat necrosis (OR, 0.29; p = 0.048). There was no difference in fat necrosis excision or cancer recurrence between the groups. CONCLUSION The closed washing system was independently associated with decreased rates of imaging-confirmed fat necrosis compared to Telfa rolling without an increase in other complications.

Abstract
Variation in numbers and functions of cells in fat tissues may affect therapeutic outcomes and adverse events after autologous fat tissue grafting in postmastectomy breast cancer patients; however, the relevant information regarding cellular components is still incomplete. Phenotypic characterization of heterogeneous cell subsets in stromal vascular fraction (SVF) isolated from fat tissues by flow cytometry was also limited to a combination of few molecules. This study, therefore, developed a polychromatic staining panel for an in-depth characterization of freshly isolated SVF and expanded adipose-derived stem cells (ADSC) from the patients. ADSC were found predominant in SVF (~65% of CD45− cells) with a homogenous phenotype of CD13+CD31−CD34+CD45−CD73+CD90+CD105−CD146− (~94% of total ADSC). Endothelial progenitor cells (EPC) and pericytes were minor (~18% and ~11% of CD45− cells, respectively) with large heterogeneity. Downregulation of CD34 and upregulation of CD105 in ADSC were profound at passage 3, showing a phenotype similar to the classical mesenchymal stem cells from the bone marrow. Results from this study demonstrated that fat tissue collected from patients contains ADSC with a highly homogenous phenotype. The in vitro culture of these cells maintained their homogeneity with modified CD34 and CD105 expression, suggesting the expansion from a single population of ADSC.

Abstract
IMPORTANCE Autologous fat grafting (AFG), or lipofilling, has been used for immediate reconstruction at the time of breast-conserving surgery in order to achieve a satisfactory cosmetic outcome in patients with breast cancer and an unfavorable tumor-to-breast volume ratio or unfavorable tumor location. However, the oncologic safety of this technique is still unclear. OBJECTIVE To determine whether AFG performed simultaneously with breast-conserving surgery is associated with differences in local relapse rates and disease-free survival. DESIGN Matched retrospective cohort study. SETTING Tertiary referral center. PARTICIPANTS Patients undergoing breast-conserving surgery with or without AFG between 2004 and 2016 were retrospectively enrolled and matched for age, staging, grade, tumor histology, and tumor immunohistochemical profile. MAIN OUTCOME(S) AND MEASURE(S) The cumulative incidence of locoregional recurrence (LRR) and disease-free survival were the primary end points, while distant recurrence and overall survival were the secondary end points. RESULTS A total of 320 patients were followed. Cases were matched with controls at a 1:4 ratio. There was no difference in LRR or distant recurrence of breast cancer between the two groups. The annual LRR rate was 0.86% in patients who received immediate AFG vs. 0.7% in patients undergoing breast-conserving surgery alone (p ≥ 0.05). Number of lymph nodes was the sole independent risk factor for local recurrence (p = 0.045). No significant differences in disease-free survival rates were found between the groups. CONCLUSIONS AND RELEVANCE At a mean follow-up of 5 years, no significant differences in locoregional recurrence rates were found between patients who received immediate AFG and those who underwent breast-conserving surgery alone. These findings corroborate previous research demonstrating the oncological safety of immediate AFG reconstruction, further suggesting that this technique as a safe, effective way to achieve optimal cosmetic outcomes in primary breast cancer surgery without jeopardizing oncologic outcomes.

Abstract
AbstractLipofilling has recently gained popularity as a tool in primary treatment of breast cancer, and its association with two-stage implant breast reconstruction is considered as standard treatment in many centers. However, no data are available about the long-term results of the association of lipofilling in combination with expander-implant reconstruction. A retrospective analysis was conducted on patients treated between January 2010 and December 2014. Two groups were compared. Group 1 had a standard expander-implant two-stage reconstruction. Group 2 underwent hybrid breast reconstruction (HBR). Patient characteristics, hospitalization, outcomes, reoperation details, outpatient visits, and evaluation questionnaires were taken into consideration. Intergroup comparison was performed using Wilcoxon Mann-Whitney U test and Pearson’s chi-square test or Fisher’s exact test for categorical variables. Two hundred fourteen patients were evaluated: 130 patients in group 1 and 84 patients in group 2. Group 2 showed significant benefits over group 1 in terms of capsular contracture rate, breast pain, and displacement/rotation of the implant (p = 0.005). The HBR protocol is associated with lower rate of capsular contracture, less breast pain at long follow-up times, and lower overall rates of revision surgery compared to standard expander-implant reconstruction. A specific cost analysis will help further clarify the advantages of this protocol over a standard procedure.Level of Evidence: Level III, risk/prognostic, therapeutic study.

Abstract
Autologous fat injection was first described roughly a century ago and has been used in surgery ever since. In addition to its use in many surgical fields, it is also frequently used for both aesthetic and reconstructive purposes in breast surgery. Since the application of fat grafting in breast surgery has steadily increased, studies investigating its reliability have simultaneously become increasingly common. Previous studies have reported that the use of fat grafting in breast surgery is reliable, but some pending questions remain about its routine use. In order to use fat grafts successfully in breast surgery, it is necessary to be familiar with the structure and content of adipose tissue, the efficacy of adipose stem cell-enriched fat grafts, the oncological safety of fat grafts, and the problems that may occur in the radiological follow-up of patients who undergo fat grafting procedures. In this literature review, we aim to discuss the use of fat grafts in breast surgery by investigating these common problems.

Abstract
Background Autologous fat grafting has broad applications in reconstructive and aesthetic breast surgery as a natural filler and for its regenerative purposes. Despite the widespread use of fat grafting, there remains no shared consensus on what constitutes the optimal fat grafting technique and its oncological safety. For this reason, the authors of this study have organized a Survey and an International Consensus Conference that was held at the Aesthetic Breast Meeting in Milan (December 15, 2018). Methods All studies on fat grafting, both for breast aesthetic and reconstructive purposes, were electronically screened. The literature review led to 17 "key questions" that were used for the Survey. The authors prepared a set of 10 "key statements" that have been discussed in a dedicated face-to-face session during the meeting. Results The 10 key statements addressed all the most debated topics on fat grafting of the breast. Levels of evidence for the key statements ranged from III to IV with 2 statements (20%) supported by a level of evidence III and 6 statements (60%) by level of evidence IV. Overall consensus was reached for 2 statements (20%) with >75% agreement reached for 7 statements. Conclusions The survey demonstrated a diversity of opinion and attitude among the panelists with regard to technique. Clear recommendations for evidence-based clinical practice for fat grafting use both in aesthetic and reconstructive breast surgery could not be defined due to the scarcity of level 1 or 2 studies.

Abstract
OBJECTIVE The aim of our systematic meta-analysis was to find out if lipofilling to the breast alters follow-up imaging procedures and leads to an increased number of biopsies because of suspicious findings. METHODS We conducted a systematic meta-analysis of the literature including all prospective and retrospective studies focusing on imaging outcomes in patients with a history of breast cancer who have received one or more lipofilling procedures after oncologic surgery to the breast. RESULTS Twelve studies met the inclusion criteria, comprising 1711 patients and at least 2261 lipofilling procedures. 564 patients (33%) were followed up only with ultrasound, 735 patients (43%) only received mammography, 273 (16%) had a combination of ultrasound, mammography and MRI, and 37 patients (2.1%) were followed up via ultrasound and mammography. A collective of 102 patients making up a matched-cohort study received ultrasound, mammography, MRI, and PET/CT, while only 51 of them made up the investigation group who had autologous fat grafting (3%). Biopsy rates were 1%-24% with a medium of 6.5% over all groups. Medium follow-up was 18.8 months (range 6-50 months). The rate of local oncologic events among the patients with lipofilling procedures detected during the study periods was 0.7%. CONCLUSION Lipofilling to the breast after oncologic operations appears to be a safe procedure with overall low biopsy and local recurrence rate. Suspicious imaging occurs in most cases out of physiologic remodeling and inflammation processes at the operation site and needs to be distinguished from malignant focusses. The amount of required biopsies stands in relation to the used imaging method and the time to follow-up.

Abstract
BACKGROUND Autologous fat transplantation is used after breast reconstruction to improve the breast profile. There are a variety of different methods used for fat harvesting, preparation, and reinjection. This study describes the specific techniques we used in this series of autologous fat transplantations in breast reconstruction patients and reports their outcomes compared with other studies in the literature. PATIENTS AND METHODS At the University Hospital of Parma between May 2012 and December 2016, we performed 53 autologous fat transplantations for secondary breast reconstruction patients with an average age of 49 years (range: 34-65 y). A tumescent fluid (NaCl, epinephrine, and a local anaesthetic) was injected, and the lipoaspirate was harvested using a closed aspiration-injection system connected to a 50 ml syringe, a 4 mm infiltration cannula, and a -650 mmHg vacuum. The average amount of lipoaspirate obtained was 100 ml (range: 50-200 ml). Centrifugation of the lipoaspirate (3000 rpm for 3 min) was performed to isolate the adipose tissue (average amount obtained, 80 ml; range: 30-180 ml). Under local anaesthesia, the retrograde injection of thin layers of fat graft in multiple tunnels was performed in the subcutaneous and/or subglandular planes. RESULTS Average follow-up was six months. Comparable to other studies, our complication rate was 7.4% (n = 4/53) and included cyst formation at the injection site (n = 1/53) and hematoma at the donor site (n = 3/53). Repeat fat grafting was performed in 28.3% of patients (n = 15/53) due to fat graft resorption. CONCLUSIONS Autologous fat transplantation is a useful procedure for correcting irregularities in the breast contour in secondary breast reconstruction.

Abstract
BACKGROUND To overcome unpredictable fat graft resorption, cell-assisted lipotransfer using stromal vascular fraction (SVF) has been introduced. However, its effect on cancer growth stimulation and its oncological safety are debatable. We investigated the effect of SVF on adjacent breast cancer and transplanted fat in a mouse model. METHODS A breast cancer xenograft model was constructed by injecting 2 × 106 MDA-MB-231-luc breast cancer cells into the right lower back of 40 NOD/SCID mice. Two weeks later, cancer size was sorted according to signal density using an in vivo optical imaging system, and 36 mice were included. Human fat was extracted from the abdomen, and SVFs were isolated using a component isolator. The mice were divided into four groups: A, controls; B, injected with 30 μl SVF; C, injected with 0.5 ml fat and 30 μl saline; group D, injected with 0.5 ml fat and 30 μl SVF. Magnetic resonance imaging and three-dimensional micro-computed tomography volumetric analysis were performed at 4 and 8 weeks. RESULTS Tumor volume was 43.6, 42.3, 48.7, and 42.4 mm3 at the initial time point and 6780, 5940, 6080, and 5570 mm3 at 8 weeks in groups A, B, C, and D, respectively. Fat graft survival volume after 8 weeks was 49.32% and 62.03% in groups C and D, respectively. At 2-month follow-up after fat grafting in the xenograft model, SVF injection showed an increased fat survival rate and did not increase the adjacent tumor growth significantly. CONCLUSION Fat grafting with SVF yields satisfactory outcome in patients who undergo breast reconstruction surgery.

Abstract
Breast cancer represents the main malignancy in women and autologous fat grafting is a diffuse procedure in the management of post-surgical breast defects causing patients’ psychosocial problems, with high costs for the public health. Recently, beneficial effects of fat grafting during post-surgical breast reconstruction have been amplified from the enrichment with human adipose-derived stem cells (ASCs) present in the stromal vascular fraction (SVF) of adult adipose tissue isolated during intraoperatory procedures. The major concern about the ASC enrichment during post-surgery breast reconstruction depends on their potential ability to release growth factors and hormones that can promote proliferation of residual or quiescent cancer cells, with the risk of de novo cancer development or recurrence. The recent description that adult stem cells primed in vitro may be vehicle for anti-cancer drug delivery offers a new vision concerning the role of ASCs in breast reconstruction after cancer surgery. Paclitaxel (PTX) is a chemotherapeutic agent acting as a microtubule-stabilizing drug inhibiting cancer cell mitotic activity. We optimized PTX loading and release in cultured ASCs and then analyzed the effects of PTX-loaded ASCs and their conditioned medium on CG5 breast cancer survival, proliferation and apoptosis in vitro, and inCG5 xenograft in vivo. We documented that ASCs can uptake and release PTX in vitro, with slight cytotoxic effects. Interestingly, PTX-loaded ASCs in co-culture, as well as conditioned medium alone, inhibited CG5 cell proliferation and survival in vitro and xenograft tumor growth in vivo. The antitumor effect of PTX-loaded ASCs may offer a new perspective concerning the use of ASCs during breast reconstruction becoming an additional local preventive chemotherapeutic agent against tumor recurrence. However, further experiments in vitro and in vivo are needed to collect more evidence confirming the efficacy and safety in cancer patients.

Abstract
BACKGROUND Autologous fat grafting (AFG) to the breast is a frequent procedure in aesthetic and reconstructive surgery. Despite pure volume gain, questions remain regarding the engraftment rate, quality, and longevity. Little is known about the role of recipient tissue or innervation of the grafted area. OBJECTIVES The goal of this study was to determine the optimal recipient layer and muscular pretreatment of AFG. METHODS Fat was grafted to the breast, pectoralis muscle, or adjacent subcutaneous tissue of 42 rats. Nerve treatment included excision of a nerve segment, botulinum toxin (BTX) injection, or no treatment. Magnetic resonance imaging (MRI) and histological workup were carried out after 2 and 6 weeks. RESULTS Six weeks after AFG, the proportion of viable fat cells within the grafted fat stayed high (median, [IQR]: 81% [72% to 85%]). The signs of inflammation decreased over time. Intramuscular grafting with intact nerves had a decreasing effect on the viability of the grafted cells compared with subcutaneous treatment (-10.21%; 95% confidence interval [-21.1 to 0.68]). CONCLUSIONS If utilized on an intact nerve, intramuscular injection may lead to inferior results. If the nerve was cut or treated with BTX; however, intramuscular injection tends to be superior. These findings may prove interesting for future studies and eventual clinical application.

Abstract
Objective to evaluate local and systemic recurrence of breast cancer in patients submitted to autologous fat grafting in the immediate reconstruction after conservative surgery for breast cancer. Methods this is a historical cohort study comparing 167 patients submitted to conservative surgery without reconstruction (conservative surgery group) with 27 patients submitted to conservative treatment with immediate graft reconstruction, following the Coleman's technique (lipofilling group). All patients had invasive carcinoma and were operated by a single surgeon from 2004 to 2011. The postoperative follow-up time was 36 months. Results the overall incidence of local recurrence was 2.4%. No patient in the lipofilling group had local recurrence during the study period. For systemic recurrence, the rates obtained were 3.7% (one patient) for the fat grafting group and 1.8% (three patients) for the conservative surgery group without reconstruction. Conclusion there was no significant difference for local or systemic recurrence in the groups studied. Immediate autologous fat grafting appears to be a safe procedure.

Abstract
Adipose-derived stem cells (ADSCs) are rapidly becoming the gold standard cell source for tissue engineering strategies and hold great potential for novel breast reconstruction strategies. However, their use in patients with breast cancer is controversial and their oncological safety, particularly in relation to local disease recurrence, has been questioned. In vitro, in vivo, and clinical studies using ADSCs report conflicting data on their suitability for adipose tissue regeneration in patients with cancer. This review aims to provide an overview of the potential role for ADSCs in breast reconstruction and to examine the evidence relating to the oncologic safety of their use in patients with breast cancer.

Abstract
BACKGROUND Autologous fat transplantation (AFT) to the breast can correct defects and be a part of a breast reconstruction to achieve a better aesthetic result. The impact of AFT on the radiological evaluation and detection of cancer remains unclarified. The aim of this study is to investigate whether AFT induces lasting modifications. METHODS In the present study, a valuation was performed of 44 breasts from 37 patients examined with mammography and ultrasound before and after autologous fat transplantation. Breast radiologists evaluated the images using a study specific protocol. RESULTS AFT did not hinder post-operative assessment of mammograms or ultrasound. No detectable changes with serious clinical impact were found after injections of mean 177 ml (34-516) of fat in one to four sessions. The rate of oil cysts was significantly higher after AFT than pre-operatively (2.3 vs. 34.1 % p = 0.0013). Significantly more post-operative oil cysts were detected after injection of larger volumes of fat (144 vs. 243 ml, p = 0.013). No significant differences were found in the post-operative images regarding age at surgery, follow-up time, or time from previous breast surgery. CONCLUSION AFT does not impair assessment of mammograms and ultrasound in patients who have a history of breast cancer surgery or prophylactic mastectomy.

Abstract
INTRODUCTION The use of autologous fat transplantation to correct volume and contour defects, scars, and asymmetry after breast cancer surgery has increased over the past 20 years. Many developments and refinements in this technique have taken place in recent years, and several studies of the safety of lipofilling in the breast have been published. PRESENTATION OF CASE We performed a literature review of this technique, highlighting the crucial role of lipofilling in breast cancer reconstruction. DISCUSSION The efficacy of the fat graft transplantation depends on the experience and the technique used by the surgeon. The ASCs (adipose-derived stem cells) contained in the fat graft has proven to be crucial for breast reconstruction by mean the regeneration of tissue, through the chemotactic, paracrine, and immunomodulatory activities and their in situ differentiation. CONCLUSION The role of lipofilling for breast reconstruction could be more significant with the application of the findings of experimental research on tissue engineering and ASCs.

Abstract
OBJECTIVES Oncological concerns have risen around the safety of adipose fat transfer (AFT) after breast cancer surgery. In this article, we present the clinical and molecular evidences, and discuss the current contradiction between them. MATERIALS AND METHODS Every clinical trial and experimental study on AFT and its oncological influences was screened. Between September 2014 and September 2016, 856 articles from four databases were found. 105 core articles were selected. RESULTS A total of 18 clinical studies have been published. The loco-regional recurrence (LRR) incidence rates range between 0 and 3.90% per year. For the mastectomy and breast conservative therapy group separately, a LRR per year between 0 and 1.62% and 0-3.90 has been reported, respectively. Some studies included a matched control group and found no significant difference between cases and controls, with the exception of a subgroup of patients with intraepithelial breast carcinoma. Adipose derived mesenchymal stem cells have a potential oncogenic effect on residual cancer cells after breast cancer surgery. Numerous signalling proteins and pathways have been described that can stimulate tumour initiation and growth. CONCLUSION There is a contradiction between experimental and clinical findings. Numerous adipokines have been discovered that could potentially promote tumour initiation and growth, but clinical studies fail to point out a significant increase in LRR in patients who receive AFT after breast cancer surgery. More prospective studies are needed with a sufficient follow-up time and analysis of some critical factors, such as adjuvant radiotherapy and hormonal therapy, the origin and volume of the injected fat, and genetic influences.

Abstract
BACKGROUND Autologous fat grafting is widely used for refinements in postmastectomy breast reconstruction. However, there are few studies evaluating outcomes in this patient population. The purpose of this study was to assess outcomes of autologous fat grafting after breast reconstruction in postmastectomy patients. METHODS We retrospectively reviewed the records of consecutive postmastectomy patients who underwent autologous fat grafting after breast reconstruction at a university center over a 5-year period. Patients with at least 6 months of follow-up were included. Medical records were reviewed for demographics, operative details, complications, incidence of palpable masses, and/or suspicious breast imaging findings requiring biopsy, and locoregional cancer recurrence. Descriptive statistics were generated. RESULTS Between January 2008 and July 2013, 108 women and a total of 167 breast reconstructions underwent autologous fat grafting for revision of postmastectomy breast reconstruction. Their ages ranged from 22 to 71 years (mean, 48 years). Fat grafts were harvested, processed, and injected using the Coleman technique. The mean number of fat grafting procedures was 1.3 (range, 1-4) per breast. Follow-up ranged from 6 to 57 months (mean, 20.2 months). Fifty-three (31.7%) breasts underwent imaging after autologous fat grafting. Suspicious imaging findings requiring biopsy were discovered in 4 (2.4%) breasts, and clinically palpable lesions combined with suspicious imaging findings requiring biopsy were present in another 4 (2.4%) breasts. All 8 biopsies showed fat necrosis, scar, or oil cysts without evidence of malignancy. One (0.6%) local complication (a wound infection at the recipient site requiring oral antibiotics) after autologous fat grafting was reported. During the limited follow-up period, there were no locoregional cancer recurrences. CONCLUSIONS Autologous fat grafting in conjunction with breast reconstruction resulted in a biopsy rate of 4.8%, and no cases of locoregional cancer recurrence were observed. Based on these preliminary findings, autologous fat grafting appears to be a relatively safe procedure for refinement of the reconstructed breast in postmastectomy patients.

Abstract
Autologous fat grafting (AFG) or lipofilling is nowadays a popular technique for breast reconstruction after breast cancer surgery. There is debate regarding the oncological safety and risks of this procedure in breast cancer patients. A systematic review of the literature published between January first 1995 and October first 2016 was conducted regarding the efficacy, safety and complications of this technique in breast cancer patients after their cancer treatment. The databases PubMed, Science Direct and Thomson Reuters Web of Science were used to search for qualified articles. Inclusion criteria were women with a personal history of breast cancer and at least one lipofilling procedure. Only studies containing a minimum of 20 patients were included in this systematic review. The search yielded a total of 23 suitable articles: 18 case series, 4 retrospective cohort studies and one prospective cohort study. The systematic review encompassed a total of 2419 patients. Medical imaging was used in the majority of the studies to assess the follow-up. Mammography was the most popular technique (65.2%), followed by ultrasound (47.8%) and MRI (30.4%). The prevalence of complications was the following: fat necrosis in 5.31%, benign lesions, like cysts or calcifications in 8.78%, infections in 0.96% and local cancer recurrence in 1.69%. AFG or lipofilling appears to be an oncological safe technique with a low morbidity in women with a history of breast cancer. In order to have a better understanding and evidence of the oncological safety a randomised controlled trial is urgently needed. We further recommend that all AFG be registered in the cancer register.

Abstract
Background: For years, the safety and effectiveness of autologous fat grafting (AFG) for breast reconstruction have been in question, with particular concern over fat necrosis, calcifications, cyst formation, and interfering with the detection of breast cancer. However, increasing evidence suggests that the complication rates and clinical results are generally acceptable to both clinicians and patients. The emerging challenge is the numerous AFG techniques and systems, where there are limited knowledge and data. The objective of this study was to conduct a literature review that focuses on the safety, effectiveness, and efficiency of various AFG techniques as applied to the breast. Methods: A PubMed search using terms related to AFG was performed over a 5-year period (April 1, 2010–April 30, 2015). Original articles focused on AFG to the breast, with outcomes on safety, effectiveness, and efficiency, were included. Results: Five hundred ninety-eight articles were identified with 36 articles included (n = 4306 patients). Satisfaction rates were high although the prevalence of complications was low—similar to previous findings. Seven studies reported average operating room time with an overall mean of 125 minutes (range: 40–210). The mean volume of fat harvested was 558 mL (range: 120–1299), and fat injected was 145 mL (range: 20–607). A positive association between injection volume and operating time was observed. Conclusions: This review validates previous findings on the safety and effectiveness of AFG to the breast and highlights its efficiency. The efficiency data available, although limited, suggest that there is an opportunity to achieve time and cost savings while not sacrificing safety and effectiveness.

Abstract
Fat grafting is increasingly popular and is becoming a common practice in plastic surgery for postmastectomy breast reconstruction and aesthetic breast augmentation; however, concerns over the oncologic safety remains a controversial and hot topic among scientists and surgeons. Basic science and laboratory research repeatedly show a potentially dangerous effect of adipose-derived stem cells on breast cancer cells; however, clinical research, although limited, continually fails to show an increase in breast cancer recurrence after breast fat grafting, with the exception of 1 small study on a subset patient population with intraepithelial neoplasm of the breast. The aim of this review is to summarize the recent conflicting basic science and clinical data to better understand the safety of breast fat grafting from an oncological perspective.

Abstract
Fat grafting in the surgical treatment of breast cancer has become popular in a short period of time because of the rising expectations of good esthetic results by the patients as well as the simplicity of the technique; however, the oncological safety for breast cancer patients remains a matter of debate. The procedure raises many questions considering that recent in-vitro studies have shown that fat grafting could promote tumor recurrence through diverse mechanisms, or even facilitate distant metastasis. We present a review of the currently available experimental and clinical data in order to describe and discuss patient selection criteria following breast cancer surgery.

Abstract
The evolution of breast reconstruction and management of breast cancer has evolved significantly since the earliest descriptions in the Edwin Smith Papyrus (3,000 BC). The development of surgical and scientific expertise has changed the way that women are managed, and plastic surgeons are now able to offer a wide range of reconstructive options to suit individual needs. Beyond the gold standard autologous flap based reconstructions, regenerative therapies promise the elimination of donor site morbidity whilst providing equivalent aesthetic and functional outcomes. Future research aims to address questions regarding ideal cell source, optimisation of scaffold composition and interaction of de novo adipose tissue in the microenvironment of breast cancer.

Autologous fat grafting in onco-plastic breast reconstruction: A systematic review on oncological and radiological safety, complications, volume retention and patient/surgeon satisfaction. J Plast Reconstr Aesthet Surg 2016; 69:742-764. [PMID: 27085611 DOI: 10.1016/j.bjps.2016.03.019] [Citation(s) in RCA: 81] [Impact Index Per Article: 10.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2015] [Revised: 03/12/2016] [Accepted: 03/19/2016] [Indexed: 12/24/2022]
Abstract
OBJECTIVE This study presents an up-to-date overview of the literature on autologous fat grafting (AFG) in onco-plastic breast reconstruction, with respect to complications, oncological and radiological safety, volume retention and patient/surgeon satisfaction. BACKGROUND Although AFG is increasingly being applied in onco-plastic breast reconstruction, a comprehensive overview of the available evidence for this procedure is still lacking. METHODS A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement was conducted. Case series, cohort studies and randomized controlled trials (RCTs) reporting on relevant outcomes of breast reconstruction with supplemental AFG were included. RESULTS In total, 43 studies were included reporting on 6260 patients with a follow-up period ranging from 12 to 136 months. The average locoregional and distant oncological recurrence rates after breast reconstruction with AFG were 2.5% (95% confidence interval (CI) 1.7-3.7) and 2.0% (95% CI 1.1-3.5), respectively. Fewer cysts and calcifications were seen on radiological images for this procedure than for other types of breast surgery. However, more biopsies were performed based on radiological findings (3.7% vs. 1.6%), and more cases of fat necrosis (9.0% vs 4.7%) were seen after treatment with AFG. The total complication rate of 8.4% (95% CI 7.6-9.1) is lower than those reported following other reconstructive breast procedures. The mean volume retention was 76.8% (range 44.7-82.6%) with a satisfaction rate of 93.4% for patients and 90.1% for surgeons. CONCLUSIONS AFG in breast reconstruction is a promising technique. Safety is not compromised as cancer recurrence and complications are not observed. Whether AFG interferes with radiological follow-up remains to be elucidated. Randomized trials with sound methodology are needed to confirm these conclusions.

Abstract
Obesity is a complex, multifactorial disease that has been extensively researched in recent times. Obesity is characterized by excess deposition of adipose tissue in response to surplus energy. Despite the negative connotations of adipose tissue (AT), it serves as a critical endocrine organ. Adipose tissue is a source of several adipokines and cytokines which have been deemed important for both normal metabolic function and disease formation. The discoveries of metabolically active brown AT in adult humans and adipose tissue derived stem cells (ADSC) have been key findings in the past decade with potential therapeutic implications. ADSCs represent an enticing pool of multipotent adult stem cells because of their noncontroversial nature, relative abundance, ease of isolation, and expandability. A decade and a half since the discovery of ADSCs, the scientific community is still working to uncover their therapeutic potential in a wide range of diseases. In this review, we provide an overview of the recent developments in the field of ADSCs and examine their potential use in transplantation and cell-based therapies for the regeneration of diseased organs and systems. We also hope to provide perspective on how to best utilize this readily available, powerful pool of stem cells in the future.
