[PMID: 39124636 PMCID: PMC11313166 DOI: 10.3390/jcm13154369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2024] [Revised: 07/18/2024] [Accepted: 07/20/2024] [Indexed: 08/12/2024] Open
Abstract
Background: Autologous fat grafting (AFG) has emerged as a useful technique in breast reconstruction. Utilizing a patient's own fat from areas like the abdomen or thighs, AFG serves various reconstruction needs. Nevertheless, the oncological safety of AFG in breast cancer patients has become a contentious issue. Concerns about its influence on cancer recurrence and detention have led to significant clinical debate and the need for thorough investigation. Methods: To determine the impact of autologous fat grafting (AFG) on loco-regional recurrence (LRR) in breast cancer survivors undergoing reconstruction, a comprehensive search of databases including PubMed, Medline, Web of Science, and Cochrane libraries was conducted from November 2023 through March 2024. This search adhered to the PRISMA guidelines and aimed to identify all the relevant studies on AFG in the context of breast reconstruction post cancer treatment. A meta-analysis was performed. Results: Out of the studies reviewed, 40 met the inclusion criteria, with a total patient cohort of 14,078. The analysis revealed that AFG had no significant association with increased rates of LRR. Conclusions: According to the available literature, AFG is a safe reconstructive option for breast cancer patients and does not increase the risk of loco-regional recurrence. Nevertheless, further well-structured long-term prospective studies are required, since heterogeneity of available studies is high and requires standardization.

Endoscopic mastectomy followed by immediate breast reconstruction with fat grafting for breast cancer. Breast Cancer 2024; 31:476-484. [PMID: 38512534 DOI: 10.1007/s12282-024-01561-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 02/24/2024] [Indexed: 03/23/2024]
Abstract
BACKGROUND Although endoscopic mastectomy has been associated with good tolerance and enhanced patient satisfaction, limitations such as the implant or flap size for reconstruction with small incisions remain unresolved. Fat grafting (FG) can expand tissue volume with pinhole skin incisions. Herein, we evaluated the safety and efficacy of endoscopic mastectomy followed by immediate FG. METHODS Patients who underwent endoscopic mastectomy with immediate FG reconstruction from 2015 to 2021 were retrospectively evaluated to establish surgical outcomes and prognosis. RESULTS Twenty-three patients with clinical stage 0 or I breast cancer underwent unilateral endoscopic mastectomy with immediate FG. The median age was 45 years (41-55), and the median body mass index was 19.3 kg/m2 (15.8-26.6). Endoscopically performed procedures included skin-sparing mastectomies in 18 patients (78%) and nipple-sparing mastectomies in five patients (22%). The median procedure duration was 295 min (242-346). The median specimen weight was 133 g (71-334), and the median grafted fat volume was 200 mL (136-320). No patient required reoperation or additional procedures for complications. One patient experienced recurrence at a median follow-up of 56.1 months and underwent resection; the patient was alive without recurrence 54 months post-resection. CONCLUSION To the best of our knowledge, this is the first report of endoscopic mastectomy with immediate FG for reconstruction. When compared with other immediate autologous reconstructions, our strategy could minimize the skin incision and procedure duration, as well as limit complications. Further prospective investigations are needed to evaluate oncological safety, surgical outcomes, and patient satisfaction.

TRANSLATIONAL BREAST CANCER RESEARCH : A JOURNAL FOCUSING ON TRANSLATIONAL RESEARCH IN BREAST CANCER 2024; 5:14. [PMID: 38751673 PMCID: PMC11093078 DOI: 10.21037/tbcr-23-54] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 03/28/2024] [Indexed: 05/18/2024]
Abstract
Background Autologous fat transfer (AFT) is gaining popularity in breast surgery, offering a natural-looking and minimally invasive approach for augmentation, reconstruction, and contouring. However, concerns about its impact on breast cancer necessitate an understanding of the interplay between transplanted adipose-derived stem cells (ADSCs) and the breast tissue microenvironment. Renowned for regeneration, ADSCs raise questions about their role in cancer promotion. This systematic review delves into the complex relationship between AFT and breast cancer, exploring how ADSCs may influence development, growth, and metastasis. Methods A systematic search of electronic databases, including PubMed, Embase, and BVS was conducted to identify relevant studies. The search strategy employed a combination of keywords, including "breast augmentation", "fat grafting", "breast enhancement", "mammoplasty", "cancer", "neoplasm" and related terms. Two reviewers independently screened titles and abstracts. Full-text articles were then retrieved for further evaluation based on their potential contribution to the review objectives. Results Two hundred and forty records were identified. Among these, 104 duplicates were removed, resulting in 136 reports available for title and abstract screening. Subsequently, 54 papers were deemed potentially eligible for inclusion, and all reports were retrieved. Conclusions In vitro studies reveal ADSCs dual role in breast cancer, influencing proliferation, migration, and drug resistance through complex signaling pathways. Animal studies highlight distinct ADSC subpopulations impacting tumor growth via direct interactions and extracellular vesicle cargo. In vivo, ADSC-enriched fat grafting is generally safe, showing no increased cancer recurrence risk compared to other methods. Notably, cases of invasive breast carcinoma warrant special attention. ADSC-enriched fat grafts exhibit potential benefits in graft retention and survival rates. Despite promising evidence, further studies are needed to comprehensively understand the intricate relationship between ADSCs and breast cancer for optimized clinical applications and potential therapeutic innovations.

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 Initial results after autologous fat transfer for treatment of thumb carpometacarpal joint osteoarthritis have been promising. But long-term results have not yet been available. METHODS In a prospective study, 42 patients with thumb carpometacarpal joint osteoarthritis were observed for a mean time of 5 years after autologous fat transfer. Manual liposuction and centrifugation were performed. Pain rating according to numerous analogue pain scale; objective force of pinch grip and fist closure; and Disabilities of the Arm, Shoulder, and Hand questionnaire score (DASH score) before and after treatment were analysed. RESULTS The average pain preoperatively was 8.0 ± 1.6 and 4.0 ± 3.0 after 5 years overall. Force and pinch force of the treated hand improved from 71% and 60% preoperative in comparison to the non-treated hand to 100% and 96%, respectively, 5 years after fat transplantation. There were similar improvements for the parameters strength and DASH score. All improvements were statistically significant. No serious adverse events were observed. CONCLUSIONS Autologous fat transplantation is a real alternative to trapeziectomy even in the long term in basal joint osteoarthritis of the thumb. The low invasiveness of the procedure and early recovery of patients compared with classical procedures such as trapeziectomy, and the superior long-term results compared with classical injection therapy, make this approach feasible as a first-line therapy in basal joint osteoarthritis of the thumb as it offers stable results and warrants a high patient satisfaction rate.

Abstract
BACKGROUND Prepectoral implant-based breast reconstruction is often supplemented by autologous fat grafting to optimize aesthetic outcomes. This usually entails several rounds of modest fat transfer to minimize risk of necrosis; however, the limits of fat grafting at expander exchange are not known. METHODS A single-institution retrospective review from July 2016 to February 2022 was performed of all patients who underwent (1) mastectomy, (2) prepectoral tissue expander placement, (3) expander exchange for implant, and (4) at least one round of autologous fat transfer. Student t test and χ2 test were used. RESULTS A total of 82 breasts underwent a single round of fat grafting during implant placement (group 1); 75 breasts underwent fat grafting that occurred in multiple rounds and/or in delay to implant placement (group 2). Group 1 received more fat at the time of implant placement (100 mL; interquartile range, 55-140 mL; P < 0.001) and underwent fewer planned operative procedures compared with group 2 (1.0 vs 2.2, P < 0.001). Total fat volume in group 2 did not significantly exceed that of group 1 until after 3 rounds of fat transfer (128.5 mL; interquartile range, 90-130 mL; P < 0.01). There was no difference in the rate of fat necrosis between groups after the first round (15.9% vs 9.3%, P = 0.2) and final round (15.9% vs 12.0%, P = 0.5) of fat grafting. Complication rates were similar between groups (3.7% vs 8.0%, P = 0.2). CONCLUSIONS A 2-stage approach of prepectoral tissue expander placement with single round of larger volume fat transfer at expander exchange reduces overall number of operative procedures without increased risks.

Abstract
Although the number of patients with breast cancer continues to rise worldwide, survival rates for these patients have significantly improved. As a result, breast cancer survivors are living longer, and quality of life after treatment is of increasing importance. Breast reconstruction is an important component that affects quality of life after breast cancer surgery. With the development of silicone gel implants in the 1960s, autologous tissue transfer in the 1970s, and tissue expanders in the 1980s, breast reconstruction has advanced over the decades. Furthermore, the advent of perforator flaps and introduction of fat grafting have rendered breast reconstruction a less invasive and more versatile procedure. This review provides an overview of recent advances in breast reconstruction techniques.

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
Objective Adipose stem cells (ASCs) have been shown in many preclinical studies to be potent suppressors of the immune system. Prior studies suggest that ASCs may promote cancer progression and wound healing. However, clinical studies investigating the effects of native, or fat-grafted adipose tissue on cancer recurrence have generated mixed results. We investigated whether adipose content in reconstructive free flaps for oral squamous cell carcinoma (OSCC) is associated with disease recurrence and/or reduction in wound complications. Study Design Retrospective chart review. Setting Academic medical center. Methods We performed a review of 55 patients undergoing free flap reconstruction for OSCC over a 14-month period. Using texture analysis software, we measured the relative free flap fat volume (FFFV) in postoperative computed tomography scans and compared fat volume with patient survival, recurrence, and wound healing complications. Results We report no difference in mean FFFV between patients with or without recurrence: 13.47 cm3 in cancer-free survivors and 17.99 cm3 in cases that recurred (p = .56). Two-year recurrence-free survival in patients with high and low FFFV was 61.0% and 59.1%, respectively (p = .917). Although only 9 patients had wound healing complications, we found no trend in the incidence of wound healing complications between patients with high versus low FFFV. Conclusion FFFV is not associated with recurrence or wound healing in patients undergoing free flap reconstruction for OSCC, suggesting adipose content should not be of concern to the reconstructive surgeon.

Review of Autologous Fat Grafting in Postmastectomy Reconstruction Patients: Nonroutine Diagnostics and Oncologic Safety. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2022; 10:e4579. [PMID: 36320622 PMCID: PMC9616633 DOI: 10.1097/gox.0000000000004579] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Accepted: 08/16/2022] [Indexed: 06/16/2023]
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 Autologous fat transfer (AFT) has an important role in breast reconstructive surgery. Nevertheless, Some concerns remain with regards to its oncological safety. We present a single center case-matching study analysing the impact of AFT in cumulative incidence of local recurrences (LR). MATERIALS AND METHODS From a prospectively maintained database, we identified 902 patients who underwent 1025 breast reconstructions from 2005 to 2017. Data regarding demographics, tumor characteristics, surgery details and follow-up were collected. Exclusion criteria were patients with distant metastases at diagnosis, recurrent tumor or incomplete data regarding primary tumor, patients who underwent prophylactic mastectomies and breast-conserving surgeries. Statistical analysis was done to evaluate the impact of the variables on the incidence of LR. A p-value < 0.05 was considered statistically significant. RESULTS After 1:n case-matching, we selected 919 breasts, out of which 425 (46.2%) patients received at least one AFT session vs 494 (53.8%) control cases. LR had an overall rate of 6.8% and we found LR in 14 (3.0%) AFT cases and 54 (9.6%) controls. Statistical analysis showed that AFT did not increase risk of LR: HR 0.337 (CI 0.173-0.658), p=0.00007. Multivariate analysis identified IDC subtype and lymph node metastases to have an increased risk of local recurrences (HR > 1). Conversely, positive hormonal receptor status was associated with a reduced risk of events (HR < 1). CONCLUSIONS AFT was not associated with a higher probability of locoregional recurrence in patients undergoing breast reconstruction therefore it can be safely used for total breast reconstruction or aesthetic refinements.LEVEL OF EVIDENCE: 3.

Abstract
Adipose-derived stem or stromal cells (ASCs) possess promising potential in the fields of tissue engineering and regenerative medicine due to their secretory activity, their multilineage differentiation potential, their easy harvest, and their rich yield compared to other stem cell sources. After the first identification of ASCs in humans in 2001, the knowledge of their cell biology and cell characteristics have advanced, and respective therapeutic options were determined. Nowadays, ASC-based therapies are on the verge of translation into clinical practice. However, conflicting evidence emerged in recent years about the safety profile of ASC applications as they may induce tumor progression and invasion. Numerous in-vitro and in-vivo studies demonstrate a potential pro-oncogenic effect of ASCs on various cancer entities. This raises questions about the safety profile of ASCs and their broad handling and administration. However, these findings spark controversy as in clinical studies ASC application did not elevate tumor incidence rates, and other experimental studies reported an inhibitory effect of ASCs on different cancer cell types. This comprehensive review aims at providing up-to-date information about ASCs and cancer cell interactions, and their potential carcinogenesis and tumor tropism. The extracellular signaling activity of ASCs, the interaction of ASCs with the tumor microenvironment, and 3 major organ systems (the breast, the skin, and genitourinary system) will be presented with regard to cancer formation and progression.

Abstract
BACKGROUND Autologous fat grating has become increasingly popular as a breast reconstructive procedure. Nevertheless, preclinical studies show that fat transfer to a previous breast cancer site could activate latent cancer cells, creating a favourable environment for disease recurrence. A systematic review and meta-analysis was performed to investigate whether fat grafting increases the risk of locoregional recurrence in patients formerly treated for breast cancer. METHODS Based on PRISMA guidelines, a systematic review searching for randomised clinical trials and matched cohorts on the topic was performed in the electronic databases Pubmed, Embase, Web of Science, and Cochrane. The date of the last search was July 20, 2021. The meta-analysis assessed the comparison of locoregional recurrence between groups. RESULTS From a total of 558 publications, data from nine matched cohorts (1.6%) reporting on 4247 subjects (1590 and 2657 subjects, respectively, in lipofilling and control groups) were suitable for inclusion in the meta-analysis. Neither of the outcomes had a statistically significant difference for disease recurrence. For the primary outcome, comparing locoregional recurrence rates between groups, the incidence rate ratio was 0.92 (95% CI: 0.68-1.26; P = 0.620). CONCLUSION The present meta-analysis, which comprises the outcomes of the individual studies with the best current evidence on the topic so far, strengthens the evidence favouring the oncologic safety of lipofilling for breast reconstruction.

TFEB, SIRT1, CARM1, Beclin-1 expression and PITX2 methylation in breast cancer chemoresistance: a retrospective study. BMC Cancer 2021; 21:1118. [PMID: 34663249 PMCID: PMC8524961 DOI: 10.1186/s12885-021-08844-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Accepted: 10/06/2021] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Breast cancer chemoresistance is attributed to a wide variety of mechanisms, including autophagy. Transcription factor EB (TFEB) has been recently identified and characterized as one major regulator of autophagy and lysosomal genesis. OBJECTIVE This study aims to evaluate the prognostic impact of TFEB and its pathway in breast cancer chemoresistance. METHODS This retrospective study analyzes the expression of TFEB, CARM1, SIRT1, and Beclin-1 and the methylation of PITX2 in breast carcinoma. A group of breast cancer patients treated with chemotherapy, who relapsed within 12 months from treatment initiation, were compared to a sub-cohort of chemo-treated patients who did not recur within 12 months of follow-up. The expression of TFEB, CARM1, SIRT1, and Belcin-1 was analyzed using immunohistochemistry or RT-PCR on formalin-fixed paraffin-embedded samples. PITX2 methylation was tested with the diagnostic CE-marked kit Therascreen PITX2 RGQ PCR. In the final model, 136 cases of chemo-treated breast cancer were included. RESULTS A higher TFEB and Beclin-1 expression correlate with shorter survival in patients with chemo-treated invasive breast cancer (respectively HR 3.46, CI.95 1.27-9.47, p < 0.05 and 7.11, CI.95 2.54-19.9). TFEB, CARM1, and SIRT1 are positively correlated with Beclin-1. The protein expression of SIRT1 is significantly associated with TFEB and CARM1 so that a very low SIRT1 expression (lower than the first quartile of the H-score distribution) correlates with a low expression of TFEB and CARM1 and with longer survival. SIRT1 seems to have a lower H-score in the basal-like and HER2-enriched tumors than the luminal subtypes. Beclin-1 and TFEB seem to have a higher H-score in the basal-like and HER2-enriched tumors than the luminal subtypes. PITX2 methylation analysis was feasible only in 65% of the selected samples, but no significant differences between cases and controls were found, and there was also no correlation with the expression of the TFEB pathway. CONCLUSIONS TFEB, SIRT1, and Beclin-1 seem to have a potential prognostic significance in patients with chemo-treated breast cancer, likely because of their role in the regulation of autophagy. In addition, no correlation between TFEB and PITX2 methylation was found, likely because they perform two different roles within the autophagy process.

Abstract
Purpose The aim of our study was to examine the surgical outcome and complications (efficiency) as well as the incidence of locoregional recurrence and distant metastases (oncological safety) in patients who underwent autologous fat grafting (AFG) of the breast following breast cancer surgery. Methods In our monocentric cohort study, retrospective and prospective data were collected from all consecutive patients who underwent AFG after breast cancer between 2008 and 2020; a total of 93 patients met the inclusion criteria. Results Our long-term results showed no increase in tumor recurrence and distant metastases in the studied collective when compared to the available literature. We observed 1 local recurrence (1.1%), 2 distant metastases (2.2%), and 1 tumor-related death (1.1%). There was a high degree of patient satisfaction; 67.12% of patients reported adequate satisfaction with autologous fat grafting. Conclusion Currently, to our knowledge, this is the study with the longest follow-up time (mean 6.7 years after AFG and 11.5 years after tumor resection). The results of our clinical study will contribute to improve evidence in the broad field of AFG, adipose stem cell and tumor research. Consistent with our study, the literature review shows a clear tendency of clinical trial results with a low incidence rate of tumor recurrence and metastasis following the use of AFG. AFG seems to be a safe procedure also after breast cancer treatment.

Abstract
BACKGROUND Autologous fat grafting has been an increasingly popular procedure for remodeling the breast of patients undergoing breast cancer surgery. This study's objective was to investigate whether autologous fat grafting is associated with a higher risk of disease recurrence in the context of late breast reconstruction for patients diagnosed with breast cancer who have undergone either breast-conserving surgery or mastectomy. METHODS A retrospective matched cohort study was performed in a single tertiary health care center. Data were collected from 42 patients formerly treated for breast cancer who underwent the first session of autologous fat grafting between August of 2007 and June of 2016. A total of 126 patients with similar features, who did not undergo autologous fat grafting, were individually matched at a 1:3 ratio with the autologous fat grafting group. The primary endpoint was locoregional recurrence. Secondary outcomes were rates of local and distant recurrences, disease-free survival, and overall survival. RESULTS At a mean follow-up of 65 months after fat grafting, no significant differences were found between the lipofilling and control groups for locoregional recurrence (7.1 percent versus 6.3 percent; p = 0.856), local recurrence (7.1 percent versus 5.6 percent; p = 0.705), distant recurrence (14.3 percent versus 7.9 percent; p = 0.238), disease-free survival (21.4 percent versus 19.0 percent; p = 0.837), and overall survival (14.3 percent versus 7.1 percent; p = 0.181). CONCLUSIONS No evidence of increased risk in any of the survival outcomes was identified. Lipofilling seems to be a safe procedure for breast reconstruction after surgical treatment of breast cancer.

Abstract
INTRODUCTION Autologous fat grafting (AFG) is a popular and effective method of breast reconstruction after mastectomy; however, the oncological safety of AFG remains in question. The aim of this study was to determine whether AFG increases the risk of cancer recurrence in the reconstructed breast. METHODS A matched, case-control study was conducted from 2000 to 2017 at the senior author's institution. Inclusion was limited to female patients who underwent mastectomy and breast reconstruction with or without AFG. Data were further subdivided at the breast level. χ analyses were used to test the association between AFG status and oncologic recurrence. A Cox proportional-hazards model was constructed to assess for possible differences in time to oncologic recurrence. The probability of recurrence was determined by Kaplan-Meier analyses and confirmed with log-rank testing. RESULTS Overall, 428 breasts met study criteria. Of those, 116 breasts (27.1%) received AFG, whereas 312 (72.9%) did not. No differences in the rates of oncologic recurrence were found between the groups (8.2% vs 9.0%, P < 1.000). Unadjusted (hazard ratio = 1.03, confidence interval = 0.41-2.60, P < 0.957) and adjusted hazard models showed no statistically significant increase in time to oncologic recurrence when comparing AFG to non-AFG. In addition, no statistical differences in disease-free survival were found (P = 0.96 by log rank test). CONCLUSION Autologous fat grafting for breast reconstruction is oncologically safe and does not increase the likelihood of oncologic recurrence. Larger studies (eg, meta analyses) with longer follow-up are needed to further elucidate the long-term safety of AFG as a reconstructive adjunct.

Abstract
BACKGROUND Time and motion studies provide a reliable methodology to quantify efficiency and establish recommendations for best practices in autologous fat grafting. The purpose of this study was to compare the rate of graft processing of three frequently used systems for graft preparation. METHODS The authors conducted a prospective randomized comparison of three methods to prepare adipose tissue for autologous fat grafting: an active filtration system (Revolve; LifeCell Corporation, Branchburg, N.J.), a passive filtration system (PureGraft 250; Cytori Therapeutics, San Diego, Calif.), and centrifugation. An independent observer collected data according to the study's behavioral checklist. The primary outcome measure was rate of adipose tissue processed. RESULTS Forty-six patients (mean age, 54 years; mean body mass index, 28.6 kg/m2) were included in the study (15 per arm; one patient was included with intention to treat after a failed screening). The rate of adipose tissue preparation was greater for the active filtration system compared with the others (active filtration: 9.98 ml/min versus passive filtration: 5.66 ml/min versus centrifugation: 2.47 ml/min). Similarly, there was a significant difference in total grafting time (active: 82.7 ± 8.51 minutes versus passive: 152 ± 13.1 minutes, p = 0.0005; versus centrifugation: 209.9 ± 28.5 minutes, p = 0.0005); however, there was no difference in total operative time (p = 0.82, 0.60). CONCLUSIONS As the number of fat grafting procedures increases, there is interest in developing techniques to harvest, process, and inject fat to improve clinical outcomes and operative efficiency. The results of this study indicate that an active fat processing system is more time efficient at graft preparation than a passive system or centrifugation.

Abstract
Background Fat grafting is now a common procedure for breast reconstruction. Many clinical studies have reported its aesthetic efficacy and oncological safety, but some experimental studies raise about the recurrence risk because of its regenerating property. This study aims to investigate the possibility of cancer recurrence associated with fat grafting. Methods In this retrospective cohort study, we analyzed a total of 339 patients who had undergone immediate reconstructive surgery after nipple-sparing mastectomy (NSM) or skin-sparing mastectomy (SSM) in our institution between February 28, 2009 and March 23, 2019. Patients who had undergone breast conserving surgery, radical mastectomy, or delayed reconstruction were excluded. We used univariate and multivariate Cox proportional hazards regression models to evaluate the association between fat grafting and cancer recurrence. Results Among the 339 patients during a median follow-up of 52 months, 27 patients (8.0%) were confirmed to have recurrent cancer. Of 67 patients who had undergone fat grafting, 10 patients were confirmed to have cancer recurrence. In multivariate analyses, fat grafting [hazard ratio (HR), 2.52; 95% CI, 1.005-6.317; P=0.0488] was independently associated with cancer recurrence. Conclusions In population of breast cancer patient who underwent immediate reconstruction in our institution, fat grafting showed significant higher risk of cancer recurrence. Although these results are at odds with many existing studies, it suggests that more careful follow-up may be necessary for patients who had undergone fat grafting after reconstructive surgery.

Abstract
Recent developments in adipose-derived stromal/stem cell (ADSC) biology provide new hopes for tissue engineering and regeneration medicine. Due to their pluripotent activity, paracrine activity, and immunomodulatory function, ADSCs have been widely administrated and exhibited significant therapeutic effects in the treatment for autoimmune disorders, neurodegenerative diseases, and ischemic conditions both in animals and human clinical trials. Cell-assisted lipotransfer (CAL) based on ADSCs has emerged as a promising cell therapy technology and significantly improved the fat graft retention. Initially applied for cosmetic breast and facial enhancement, CAL has found a potential use for breast reconstruction in breast cancer patients. However, more challenges emerge related to CAL including lack of a standardized surgical procedure, the controversy in the effectiveness of CAL, and the potential oncogenic risk of ADSCs in cancer patients. In this review, we summarized the latest research and intended to give an outline involving the biological characteristics of ADSCs as well as the preclinical and clinical application of ADSCs.

Abstract
The procedural volume of autologous fat grafting (AFG) has risen over the past several years, specifically in the setting of breast reconstruction, despite controversy surrounding its oncologic safety. While some in vitro and animal models have cast doubt on the oncologic safety of AFG, there is no clinical evidence that AFG in breast reconstruction is associated with an increased risk of cancer development or recurrence or an inability to adequately assess changes in the breast. That being said, recommendations regarding surveillance and follow-up after AFG in breast reconstruction are largely surgeon directed and differ across practices. The purpose of this review is to summarize the current literature and provide evidence-based recommendations.

Effect of Breast Cancer and Adjuvant Therapy on Adipose-Derived Stromal Cells: Implications for the Role of ADSCs in Regenerative Strategies for Breast Reconstruction. Stem Cell Rev Rep 2020; 17:523-538. [PMID: 32929604 DOI: 10.1007/s12015-020-10038-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/04/2020] [Indexed: 12/14/2022]
Abstract
Tissue engineering using Adipose Derived Stromal Cells (ADSCs) has emerged as a novel regenerative medicine approach to replace and reconstruct soft tissue damaged or lost as a result of disease process or therapeutic surgical resection. ADSCs are an attractive cell source for soft tissue regeneration due to the fact that they are easily accessible, multipotent, non-immunogenic and pro-angiogenic. ADSC based regenerative strategies have been successfully translated to the clinical setting for the treatment of Crohn's fistulae, musculoskeletal pathologies, wound healing, and cosmetic breast augmentation (fat grafting). ADSCs are particularly attractive as a source for adipose tissue engineering as they exhibit preferential differentiation to adipocytes and support maintenance of mature adipose graft volume. The potential for reconstruction with an autologous tissue sources and a natural appearance and texture is particularly appealing in the setting of breast cancer; up to 40% of patients require mastectomy for locoregional control and current approaches to post-mastectomy breast reconstruction (PMBR) are limited by the potential for complications at the donor and reconstruction sites. Despite their potential, the use of ADSCs in breast cancer patients is controversial due to concerns regarding oncological safety. These concerns relate to the regeneration of tissue at a site where a malignancy has been treated and the impact this may have on stimulating local disease recurrence or dissemination. Pre-clinical data suggest that ADSCs exhibit pro-oncogenic characteristics and are involved in stimulating progression, and growth of tumour cells. However, there have been conflicting reports on the oncologic outcome, in terms of locoregional recurrence, for breast cancer patients in whom ADSC enhanced fat grafting was utilised as an alternative to reconstruction for small volume defects. A further consideration which may impact the successful translation of ADSC based regenerative strategies for post cancer reconstruction is the potential effects of cancer therapy. This review aims to address the effect of malignant cells, adjuvant therapies and patient-specific factors that may influence the success of regenerative strategies using ADSCs for post cancer tissue regeneration.

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
Background The transplantation of autologous fat is an increasingly common but not standardized procedure in aesthetic and reconstructive surgery. Until now only studies about the short-term results after transplantation with autologous fat have been published. In this publication we present our results of a long-term study after fat transplantation.Patients/Material and Methods 14 patients underwent an MRI investigation which was done before and 5-9 years (mean 6 years) years after aesthetic breast lipofilling according to BEAULI-protocol. The difference in volume was calculated with the open source software OsiriX. Two groups were analyzed separately to calculate the influence of body weight changes in final volume gain. In the first group patients with a stable BMI (increase of less than 1 kg/m2) were included. The second group includes patients with a BMI gain exceeding more than 1 kg/m2. The mean increase in BMI was 1,6 kg/m2 (minimum 0 - maximum 3,9). None of the patients lost weight.Results Depending on the desired amount of breast augmentation the patients underwent between one to four operations. An average of 176 ml fat was transplanted per breast and surgery. In the first group a mean volume survival of 74 % (IQR 58 % - 92 %) was observed. In the second group an increase of 135 % (IQR 105 % - 318 %) of the volume of transplanted fat was observed. After an intermediate weight loss one of the patients regained her initial weight.Conclusion In this study the transplantation of autologous fat renders good long-term results. There is a significant correlation between change of weight and fat transplant volume survival over the years. This also explains the very high increase in breast volume in some patients. Autologous fat transplantation seems to be a safe and efficient method for breast augmentation. For further statements studies with larger number of cases are necessary.

Abstract
BACKGROUND Autologous fat grafting is a useful adjunct following breast reconstruction. The impact of autologous fat grafting on oncologic safety and surveillance remains questionable, particularly following breast conservation therapy. METHODS The authors performed a retrospective review of patients who underwent delayed fat grafting following breast conservation therapy between 2006 and 2016. A control group of conservatively managed patients without grafting was matched for cancer stage, age, body mass index, and follow-up. Outcomes included locoregional recurrence and oncologic surveillance. RESULTS Seventy-two patients were identified per cohort. There were no differences in median age (50 years versus 51 years; p = 0.87), body mass index (28.2 kg/m versus 27.2 kg/m; p = 0.38), or length of follow-up (61.9 months versus 66.8 months; p = 0.144) between controls and grafted patients, respectively. Overall, four patients in each cohort experienced recurrence (5.6 percent; p = 1.00) with similar cumulative incidence estimates observed (log-rank test, p = 0.534). There were no significant differences in palpable mass (9.7 percent versus 19.4 percent; p = 0.1), fat necrosis (34.7 percent versus 33.3 percent; p = 0.86), calcifications (37.5 percent versus 34.7 percent; p = 0.73), or indication for breast biopsy (15.3 percent versus 22.2 percent; p = 0.23) between breast conservation and breast conservation therapy plus autologous fat grafting cohorts, respectively. CONCLUSIONS Overall, the authors found no difference in recurrence rates after breast conservation with or without delayed fat grafting. Furthermore, there were no differences in the rates of fat necrosis, palpable mass, and abnormal radiographic findings. This study represents the longest follow-up to date in in a large matched study of autologous fat grafting with breast conservation therapy demonstrating oncologic safety and no interference with follow-up surveillance.

Abstract
Autologous breast reconstruction historically required flaps that were invasive, required prolonged operative times and recoveries, and resulted in varying degrees of donor site morbidity. We present our early results with a minimally invasive completely autologous breast reconstruction technique utilizing buried dermato-cutaneous (DMC) flaps and immediate fat grafting. A 25-patient, 43-breast consecutive case series is presented.

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 Fat grafting is a powerful and increasingly used technique in breast reconstruction. However, fat necrosis can lead to palpable postoperative changes that can induce anxiety and lead to unplanned diagnostic studies. The authors' aim in this study was to evaluate the incidence, type, and timing of these unanticipated studies; the specialty of the ordering provider; and the factors that trigger the ordering process. METHODS A retrospective chart review was conducted for patients from 2006 to 2015 who underwent fat grafting as part of implant-based breast cancer reconstruction and had at least 1-year follow-up after fat grafting. RESULTS From 2006 to 2015, 166 patients underwent fat grafting as part of implant-based breast reconstruction. Forty-four women (26.5 percent) underwent at least one imaging procedure. Thirteen women (7.8 percent) underwent 17 biopsies. For a palpable mass, the initial imaging test most commonly ordered was ultrasound, followed by mammography/ultrasound. The percentage of patients with a diagnosis of fat necrosis on mammography, ultrasound, and biopsy was 4.2, 12.7, and 5.4 percent, respectively. Seven patients (4.2 percent) had distant metastases. Tissue diagnosis of local recurrence was never identified. Mean follow-up was 2.4 years. CONCLUSIONS Fat-grafting sequelae may lead to early unplanned invasive and noninvasive procedures initiated by a variety of providers. In this study, fat grafting had no impact on local recurrence rate. As use of fat grafting grows, communication among breast cancer care providers and enhanced patient and caregiver education will be increasingly important in optimizing the multidisciplinary evaluation and monitoring of palpable breast lesions.

Abstract
Adipose stem cells (ASCs) are a crucial element in bone tissue engineering (BTE). They are easy to harvest and isolate, and they are available in significative quantities, thus offering a feasible and valid alternative to other sources of mesenchymal stem cells (MSCs), like bone marrow. Together with an advantageous proliferative and differentiative profile, they also offer a high paracrine activity through the secretion of several bioactive molecules (such as growth factors and miRNAs) via a sustained exosomal release which can exert efficient conditioning on the surrounding microenvironment. BTE relies on three key elements: (1) scaffold, (2) osteoprogenitor cells, and (3) bioactive factors. These elements have been thoroughly investigated over the years. The use of ASCs has offered significative new advancements in the efficacy of each of these elements. Notably, the phenotypic study of ASCs allowed discovering cell subpopulations, which have enhanced osteogenic and vasculogenic capacity. ASCs favored a better vascularization and integration of the scaffolds, while improvements in scaffolds' materials and design tried to exploit the osteogenic features of ASCs, thus reducing the need for external bioactive factors. At the same time, ASCs proved to be an incredible source of bioactive, proosteogenic factors that are released through their abundant exosome secretion. ASC exosomes can exert significant paracrine effects in the surroundings, even in the absence of the primary cells. These paracrine signals recruit progenitor cells from the host tissues and enhance regeneration. In this review, we will focus on the recent discoveries which have involved the use of ASCs in BTE. In particular, we are going to analyze the different ASCs' subpopulations, the interaction between ASCs and scaffolds, and the bioactive factors which are secreted by ASCs or can induce their osteogenic commitment. All these advancements are ultimately intended for a faster translational and clinical application of BTE.

Abstract
There has been a shift in recent years toward a growing popularity of implant-based breast reconstruction, especially in the setting of increased frequency of concurrent contralateral prophylactic mastectomy. Advancements in implant safety and technology have also allowed for an expanding implant reconstruction practice across the country. The traditional approach is immediate two-stage implant reconstruction with placement of a tissue expander within a subpectoral pocket. The introduction of acellular dermal matrix has revolutionized implant-based breast reconstruction, allowing surgeons the opportunity to minimize morbidity while maximizing aesthetic outcomes. There have also been advances in the management of postoperative pain control as well as secondary revision surgery.

Abstract
Given the widespread utility and therapeutic potential of autogenous fat grafting, plastic surgeons should be familiar with its safety profile and associated adverse events. This article provides a critical review of the literature and delineates risk factors associated with various complications when grafting to the breast and gluteal regions. The majority of adverse events are related to fat necrosis and require minimal diagnostic or therapeutic intervention. Larger graft volumes, as in cosmetic augmentation, are associated with higher incidences of fatty necrosis. The oncologic safety of fat grafting is supported by multiple clinical studies with thousands of breast cancer patients, albeit predominantly retrospective in nature. Although less frequent, serious complications include fat emboli during gluteal augmentation. Identification of associated risk factors and implementation of proper surgical techniques may minimize the occurrence of life-threatening complications.

Abstract
Introduction In the surgical world of breast cancer reconstruction, fat grafting is commonly viewed as an oncogenic risk. Scientific studies add confusion, given the stark lack of clinical evidence suggesting pro-oncogenic links. Typically, classic migration assays (e.g., Boyden chamber) between adipose-derived stem cells and breast cancer cells define this cell relationship as pro-oncogenic. Objective We sought to develop a new migration model which better explains existing clinical data. Methods Silicon chambers were used to seed isolated populations of cells simultaneously in culture dish. Once cells had adhered, chambers were removed and cells were allowed to follow natural trophic cues. Multiple permutations of MDA-MB-231, MCF-7, HS-27, and ASCs were engineered. Cells were stained with MitoTracker for fluorescent visualization. A human cytokine array (RayBiotech) was performed on the media of migrating assays. Cellular tropism and blot intensity were quantitatively measured in Image J. Results An in vitro model was successfully constructed where ASCs reproducibly and freely migrated. Cytokine arrays reveal higher levels of IL-6 and CCL2 in the media of Boyden chambers containing ASCs and MDA-MB-231, compared to the novel assay, comprised of the same cell numbers, types, and incubation times. Conclusion These data collectively show for the first time the attraction of ASCs to malignant breast cancer cells; a phenomenon which many ASC studies infer. The cytokine profile of the novel system described is less oncogenic than the commonly described Boyden chamber. These data integrate better into the clinical data, which fail to link cancer recurrence with fat grafting.

Abstract
Growing importance has been attributed to interactions between tumors, the stromal microenvironment and adult mesenchymal stem cells. Adipose-derived stem cells (ASCs) are routinely employed in regenerative medicine and in autologous fat transfer procedures. To date, clinical trials have failed to demonstrate the potential pro-oncogenic role of ASC enrichment. Nevertheless, some pre-clinical studies from in vitro and in vivo models have suggested that ASCs act as a potential tumor promoter for different cancer cell types, and support tumor progression and invasiveness through the activation of several intracellular signals. Interaction with the tumor microenvironment and extracellular matrix remodeling, the exosomal release of pro-oncogenic factors as well as the induction of epithelial-mesenchymal transitions are the most investigated mechanisms. Moreover, ASCs have also demonstrated an elective tumor homing capacity and this tumor-targeting capacity makes them a suitable carrier for anti-cancer drug delivery. New genetic and applied nanotechnologies may help to design promising anti-cancer cell-based approaches through the release of loaded intracellular nanoparticles. These new anti-cancer therapies can more effectively target tumor cells, reaching higher local concentrations even in pharmacological sanctuaries, and thus minimizing systemic adverse drug effects. The potential interplay between ASCs and tumors and potential ASCs-based therapeutic approaches are discussed.

Making Sense of Stem Cells and Fat Grafting in Plastic Surgery: The Hype, Evidence, and Evolving U.S. Food and Drug Administration Regulations. Plast Reconstr Surg 2019; 143:417e-424e.

Abstract
Autologous fat grafting and adipose-derived stem cells are two distinct entities with two different risk profiles, and should be regulated as such. Autologous fat grafting prepared with the additional step of stromal vascular fraction isolation is considered a form of "stem cell therapy" given the high concentration of stem cells found in stromal vascular fraction. Much ambiguity existed in the distinction between autologous fat grafting and stromal vascular fraction initially, in terms of both their biological properties and how they should be regulated. The market has capitalized on this in the past decade to sell unproven "stem cell" therapies to unknowing consumers while exploiting the regulatory liberties of traditional fat grafting. This led to a Draft Guidance from the U.S. Food and Drug Administration in 2014 proposing stricter regulations on fat grafting in general, which in turn elicited a response from plastic surgeons, who have safely used autologous fat grafting in the clinical setting for over a century. After a series of discussions, the U.S. Food and Drug Administration released its Final Guidance in November of 2017, which established clear distinctions between autologous fat grafting and stromal vascular fraction and their separate regulations. By educating ourselves on the U.S. Food and Drug Administration's final stance on fat grafting and stem cell therapy, we can learn how to navigate the regulatory waters for the two entities and implement their clinical use in a responsible and informed manner.

Abstract
LEARNING OBJECTIVES After reading this article, the participant should be able to: 1. Develop a practical method for preoperative implant size selection. 2. List characteristics and examples of fourth- and fifth-generation silicone implants. 3. Recognize the differences in "profile" designations across implant manufacturers. 4. Recall updated statistics on breast implant-associated anaplastic large cell lymphoma and describe current guidelines on disease diagnosis and treatment. 5. Apply atraumatic and aseptic surgical techniques in primary breast augmentation. SUMMARY Modern primary breast augmentation requires an intimate knowledge of the expanding breast implant market, including characteristics of current generation silicone implants and "profile" types. Optimal implant size selection requires balancing patient desires with tissue qualities. Evidence and awareness of breast implant-associated anaplastic large cell lymphoma continue to grow, and patients and surgeons alike should be informed on the most updated facts of the disease entity. Atraumatic surgical technique and aseptic adjuncts are critical in reducing periprosthetic inflammation and contamination, both of which are known instigators of capsular contracture and potentially breast implant-associated anaplastic large cell lymphoma.

Abstract
Purpose Indications for nipple-sparing mastectomy (NSM) have broadened to include the risk reducing setting and locally advanced tumors, which resulted in a dramatic increase in the use of NSM. The Oncoplastic Breast Consortium consensus conference on NSM and immediate reconstruction was held to address a variety of questions in clinical practice and research based on published evidence and expert panel opinion. Methods The panel consisted of 44 breast surgeons from 14 countries across four continents with a background in gynecology, general or reconstructive surgery and a practice dedicated to breast cancer, as well as a patient advocate. Panelists presented evidence summaries relating to each topic for debate during the in-person consensus conference. The iterative process in question development, voting, and wording of the recommendations followed the modified Delphi methodology. Results Consensus recommendations were reached in 35, majority recommendations in 24, and no recommendations in the remaining 12 questions. The panel acknowledged the need for standardization of various aspects of NSM and immediate reconstruction. It endorsed several oncological contraindications to the preservation of the skin and nipple. Furthermore, it recommended inclusion of patients in prospective registries and routine assessment of patient-reported outcomes. Considerable heterogeneity in breast reconstruction practice became obvious during the conference. Conclusions In case of conflicting or missing evidence to guide treatment, the consensus conference revealed substantial disagreement in expert panel opinion, which, among others, supports the need for a randomized trial to evaluate the safest and most efficacious reconstruction techniques.

Abstract
Breast reconstruction proceeding cancer treatment carries risk, regardless of the type of surgery. From fat grafting, to flap placement, to implants, there is no guarantee that reconstruction will not stimulate breast cancer recurrence. Research in this field is clearly divided into two parts: scientific interventional studies and clinical retrospective evidence. The reconstructive procedure offers hypoxia, a wound microenvironment, bacterial load, adipose derived stem cells; agents shown experimentally to cause increased cancer cell activity. This is compelling scientific evidence which serves to bring uncertainty and fear to the reconstructive procedure. In the absence of clinical evidence, this laboratory literature landscape is now informing surgical choices. Curiously, clinical studies have not shown a clear link between breast cancer recurrence and reconstructive surgery. Where does that leave us? This review aims to analyze the science and the surgery, thereby understanding the oncological fear which accompanies breast cancer reconstruction.

Abstract
As surgical methods continue to evolve and patients become more educated consumers of their medical care, both oncologic breast surgeons and reconstructive plastic surgeons should understand the current options for surgical management of breast cancer. This review evaluates the current autologous breast reconstruction options following nipple sparing mastectomy (NSM). A comprehensive review of the current literature discussing autologous reconstruction after NSM was performed. Fat grafting alone has been used to reconstruct small to medium sized-breasts over multiple injection sessions. Goldilocks mastectomy-like reconstructions can be used for larger, more ptotic breasts. Pedicled latissimus dorsi (LD) flaps can be used, but usually need to be modified to ensure sufficient breast volume. While the lower abdominal tissue remains the most common donor site in free tissue transfer, other donor sites can be used if there is insufficient volume or inadequate perforators. Periareolar incisions are associated with the highest rates of overall complications and nipple areola complex necrosis. It has not been determined whether implant-based or autologous reconstructions have lower complication rates. Both prior radiation and large, ptotic breasts present unique challenges during reconstruction. Overall, there is a high rate of patient satisfaction with breast reconstruction following NSM. Autologous breast reconstruction after NSM is a safe method of breast cancer surgical management with aesthetically excellent results. Multiple techniques have been described along the reconstructive ladder. Special consideration should be given to choices of incision, previously irradiated breasts, and large, ptotic breasts.

Abstract
BACKGROUND Breast conserving surgery (BCS) and radiotherapy (RT) often lead to breast deformity. Reconstruction of these defects is a surgical challenge. Lately, the popularity of autologous fat grafting in these patients is growing. The purpose of this study was to assess clinical outcomes and aesthetic results of autologous fat grafting after BCS and RT. MATERIALS AND METHODS A database of all patients who underwent fat grafting after BCS and RT was prospectively maintained. Patient demographics, clinical and surgical characteristics and intra- and postoperative complications were analysed. Preoperative and 6-month postoperative photographs were evaluated by a four-member expert-panel assessing the aesthetic outcome (Harvard scale, five-point aesthetic scale and an overall score). RESULTS Between June 2008 and January 2016, 109 consecutive patients (114 breasts) underwent 222 fat grafting procedures. The mean clinical postoperative follow-up was 26 ± 19 months (range 10-97). The median number of fat grafting sessions sufficient for a satisfactory surgical result was two (range 1-6). Localized infections occurred in four patients, all treated effectively with oral antibiotics. Fat necrosis that required excision under local anaesthesia occurred once. The overall cosmetic appearance was rated 5.1/10 before and 7.2/10 after reconstruction (p < 0.01). A significant improvement was noted in breast symmetry, volume, shape and scarring. CONCLUSION Fat grafting after BCS and RT provides significant aesthetic improvement of the breast. It has a positive effect on the postsurgical scar and irradiated tissue and helps to restore the volume deficit, which makes it suitable as a reconstructive approach in this patient group.

Abstract
BACKGROUND To investigate the effect moderate intermittent negative pressure breast reconstructive model exerts on human triple negative breast cancer cell (TNBC) invasion and explore the related mechanism. METHODS The human TNBC cell line MDA-MB-231 was used. Cells in external volume expansion (EVE) group were exposed to an intermittent -25 mmHg for 12 h; the pressure for non-EVE group was constantly 0 mmHg. In vivo, MDA-MB-231 cell suspensions were injected subcutaneously into dorsal skin of nude mice (n = 27 mice/group). Tumors on mice in EVE group received -25 mmHg suction 3 h/day; while mice in non-EVE group were under normal pressure. Cell invasion assay, ELISA, RT-PCR, western blot analysis and immunohistochemistry were used to evaluate the inflammation, epithelial-mesenchymal transition (EMT) and angiogenesis between the two groups in both vitro and vivo experiments. RESULTS MDA-MB-231 cells in the EVE group were more invasive and had higher expressions of IL-8 (30.02 ± 10.44 pg/ml vs. 18.82 ± 9.26 pg/ml, P < 0.05) and TNF-α (20.59 ± 4.72 pg/ml vs. 14.10 ± 3.36 pg/ml, P < 0.05) than the non-EVE group. Grafted MDA-MB-231 tumors in EVE group showed a more obvious epithelial-mesenchymal transition at 2 week and better angiogenesis at 2 and 4 week, respectively. CONCLUSION Moderate intermittent negative pressure induces MDA-MB-231 cells to be more invasive. Future studies should figure out other effects this intervention may bring. Clinical studies should also be conducted to further evaluate its safety and optimize the clinical model.

Abstract
BACKGROUND Lipofilling is performed in breast cancer patients to optimize the aesthetic outcome following breast reconstruction after mastectomy. Despite its common usage worldwide, little is known about the interaction of the lipoaspirate and dormant cancer cells. Up to date, no risk factors that increase the risk for cancer recurrence have been established. This study aims to identify risk factors for lipofilling candidates after breast cancer and questions the oncological safety of lipofilling in lymph node positive disease. METHODS Matched retrospective cohort study: the disease-free survival (DFS) between 100 breast cancer patients undergoing a lipofilling after their DIEP-flap reconstruction and 100 matched control patients with no subsequent lipofilling was analyzed. Further, patients were subdivided according to risk factors, which were categorized as patient-dependent factors (PDFs) and tumor-dependent factors (TDFs). DFS and hazard ratios (HR) were compared to identify potential risk factors that may increase cancer recurrence. RESULTS Median follow-up was 76.5 months from the mastectomy, and 31 months from the startpoint to the end of follow-up. Seven and eleven patients had recurrence in the lipofilling and control group, respectively, presenting with comparable DFS rates and an insignificant HR =0.57, 95% confidence interval (CI): 0.22-1.47, P=0.24. According to subgroup survival analysis, lipofilling increased the risk of recurrence in women with a positive nodal status (P=0.035) and a high-grade neoplasia (P=0.049). CONCLUSIONS No general increased recurrence risk was observed between the lipofilling and control group. The subgroup analysis identified high-grade neoplasia and positive nodal status to be a risk factor for cancer recurrence. Patients with a known node positive disease have an increased risk of occult micrometastases in their lymph nodes. Further studies are necessary to clarify whether dormant breast cancer cells in form of micrometastases in the lymph nodes can be reactivated by the factors secreted by adipose derived stem cells.
