Abstract
PURPOSES Breast deformity occurring in the lower pole after breast conserving surgery (BCS) is known as bird's beak (BB) deformity. This retrospective study evaluated the outcomes in breasts reconstructed with a conventional closing procedure (CCP) and a downward-moving procedure (DMP), respectively, after BCS. METHODS In CCP, the inferomedial and inferolateral portions of breast tissues were reapproximated toward the midline after wide excision to repair the breast defect. In DMP, the retro-areolar breast tissue was detached from the nipple-areolar complex after wide excision, and the upper pole breast tissue was moved downward to refill the breast defect. RESULTS CCP was performed in 20 patients (Group A), and DMP was performed in 28 patients (Group B). Although retraction of the lower part of the breast was postoperatively observed in 13 (72%) of 18 patients from Group A, it was observed in 7 (28%) of 25 patients in Group B (p < 0.05). The downward pointing of the nipple was observed in 8 (44%) of 18 patients from Group A and in 4 (16%) of 25 patients in Group B (p < 0.05). CONCLUSIONS DMP is more useful for preventing BB deformity than CCP.

Abstract
Breast conservative treatment (BCT) is currently accepted as the standard treatment option for breast cancer. Targeted ultrasound helps detect recurrent lesions, postoperative changes, and scarring tissue. In this pictorial essay, we review the ultrasound features of benign (seroma, hematoma, fat necrosis, traumatic neuroma, fibrosis/scarring) and malignant (recurrence, new primary cancer) causes of palpable lumps after BCT and provide images from our patients to illustrate some typical findings of common pathologies. Ultrasound, especially as an adjunct to mammography, can make a specific diagnosis in most cases.

Abstract
BACKGROUND Heparin prophylaxis for venous thromboembolism can be used in microsurgery. If vein anastomosis is performed before the artery, heparin irrigation into the artery can be performed locally without systematic effect. This study aimed to introduce this "intraflap perfusion procedure" in autologous breast reconstruction. METHODS Among the 220 patients with unilateral breast cancer who had received the free abdominal flap, we retrospectively compared those that had undergone the intraflap perfusion procedure (n = 108) and those who did not (n = 112). A 10 mL injection of heparinized physiological saline solution (100 units/mL) was administered into the deep inferior epigastric artery. Intraflap perfusion was performed before, during, and after vein anastomosis, without the vessel clip of the vein. Artery anastomosis was performed without the use of a vein clamp. Further, vein anastomosis was performed tightly to prevent leakage from the vein anastomosis site during artery anastomosis. RESULTS The rates of superficial inferior epigastric vein (SIEV) superdrainage (18.5% vs. 42.0%, P < 0.001), and intraoperative flap congestion (0.9% vs. 8.0%, P = 0.01) were significantly lower in patients undergoing this procedure. There were no significant differences regarding other factors (age, BMI, laterality, comorbidities, and other operative details). CONCLUSIONS Intraflap perfusion prevented long-term stasis at the venous anastomosis site and capillary level. It could reduce flap congestion. SIEV superdrainage was performed to manage flap congestion, particularly in patients who did not undergo this procedure. Consequently, it can be inferred that this procedure reduces the rate of superdrainage.

Use of polysaccharide hemostatic agent (HaemoCer™) in breast cancer surgery to reduce postoperative complications: A randomised controlled trial. Int Wound J 2023; 20:925-934. [PMID: 36448255 PMCID: PMC10031209 DOI: 10.1111/iwj.13939] [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: 06/05/2022] [Revised: 08/08/2022] [Accepted: 08/09/2022] [Indexed: 12/05/2022] Open
Abstract
Postoperative wound-site bleeding, tissue inflammation and seroma formation are well-known complications in the field of breast surgery. Hemostatic agents consisting of polysaccharides may be used intra-operatively to minimise postoperative complications. We conducted a prospective randomised-controlled, single-centre study including 136 patients undergoing breast-conserving surgery for invasive or intraductal breast cancer. Of these, 68 patients were randomised to receive an absorbable polysaccharide hemostatic agent into the wound site during surgery, while 68 patients were randomised to the control group and did not receive any hemostatic agent. Primary outcome was the total volume of postoperative drained fluid from the surgical site. Secondary outcomes were the number of days until drain removal and rate of immediate postoperative surgical site infection Patients in the intervention group had significantly higher drainage output volumes compared with the control group 85 mL (IQR 46.25-110) versus 50 mL (IQR 30-75), respectively; (P = .003). Univariable linear regression analyses showed a significant association between the surgical specimen and the primary outcome (P < .001). After multivariable analysis, the use of absorbable polysaccharide hemostatic product was no longer significantly associated with a higher drainage output and only the size of the surgical specimen remained a significant predictor. The number of days until drainage removal and the postoperative seroma formation were higher in the intervention group (P = .004) and (P = .003), respectively. In our study, intraoperative application of polysaccharide hemostatic agent during breast-conserving surgery did not decrease postoperative fluid production. Only the size of the surgical specimen was significantly associated with postoperative drainage volume.

Treating Pain and Fat Necrosis after Breast Cancer Surgery with Fat Grafting: Is one Session Enough? Aesthetic Plast Surg 2022; 46:2677-2688. [PMID: 35804155 DOI: 10.1007/s00266-022-02983-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 06/04/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND Chronic pain after breast cancer surgery is affecting up to 60% of patients, causing significant morbidity to patients. Lately, fat grafting has been applied as a therapy for chronic neuropathic pain. METHODS We report a series of eighteen patients, who were treated for pain after breast cancer surgery. Twelve patients had a breast conserving therapy, two a mastectomy and four an autologous flap-based reconstruction. While most presented with neuropathic pain, six patients had fat necrosis in their history. Most patients presented with severe pain (77%) and were treated with fat grafting sessions, performed by water-assisted liposuction. RESULTS All patients responded to the interventions; the median number of fat grafting sessions was 2, the median duration of the interventions was 4 months, and the median follow-up period was 56.5 months. The median pain prior to the fat grafting procedure had an intensity of 8 (range 7-9) numeric rating scale points; after the first intervention, this was reduced to 4 (range 2.3-5.8); and after the second intervention, it was down to 2 (range 0.8-3.3). Patients with pain intensities of 4-5 had a good chance of achieving analgesia after one session. CONCLUSIONS Fat grafting could be a new treatment modality for symptomatic fat necrosis: complete or partial suction of the necrosis and/or fat grafting around the necrosis to reduce inflammation and pain. Fat grafting proved a valuable tool, reducing pain or even achieving analgesia after breast cancer surgery presenting with a highly favorable risk-benefit ratio.

Abstract
BACKGROUND Flap blood glucose (FBG) measurement is proposed as a monitoring technique. A cause of long-lasting fever could be derived from fat necrosis. If the findings of low FBG correlated with fat necrosis, it could predict the poor cosmetic result and a source of fever. However, this correlation remained unsolved. The purpose of this study was to clarify this correlation in breast reconstruction. METHODS In the 180 unilateral breast cancer patients (mean age = 49.8 years) performed free abdominal flap, we retrospectively compared the group where fat necrosis occurred with the group where it did not occur (45 patients with fat necrosis vs. 135 patients without). We compared the average of FBG in each postoperative day. RESULTS The average FBG was significantly lower in patients with fat necrosis in the second postoperative day (115.3 ± 27.3 vs. 126.3 ± 13.7 mg/dl, p = .026) and the third postoperative day (111.1 ± 22.1 vs. 118.8 ± 13.8 mg/dl, p = .036). Mean BMI and inserted total flap weight were significantly higher in patients with the fat necrosis group (24.8 vs. 22.9 kg/m2 , p = .005) (617 vs. 478 g, p = .006). The multivariate analysis revealed early FBG (OR = 0.96, p = .0002) and laterality (right side) (OR = 0.46, p = .043) were independently significant predictors. There were no significant between-group differences regarding other factors (age, systemic blood glucose, comorbidities and operative details). CONCLUSIONS The possibility of fat necrosis was high for patients with low FBG in the early postoperative day.

Abstract
BACKGROUND There is little information on the risk factors for fat necrosis after breast-conserving surgery using an inframammary adipofascial flap (IAF). METHODS We conducted a retrospective cohort study from a single institution evaluating the risk factors for fat necrosis after breast-conserving surgery using an IAF (n = 41) performed from 2005 to 2020 for newly diagnosed stage 0-2 breast cancer or phyllodes tumor. RESULTS Age (≥50 years of age vs. <50 years of age), mammographic density (fatty vs. other) and operation period (before vs. after revision of surgical procedure and patient indication) were significantly associated with fat necrosis (p = 0.006, p = 0.04 and p = 0.02, respectively). CONCLUSION Our study suggested that the use of an IAF with crescent dermis and selection of appropriate cases for IAF after breast-conserving surgery may be useful for the purpose of reducing fat necrosis. Further study is needed.

Abstract
Fat necrosis of the breast is a benign non-suppurative inflammation of the adipose tissue and often mimics breast cancers, posing a diagnostic challenge for the clinician and radiologist. It has a myriad of appearances on different imaging techniques, ranging from the pathognomic oil cyst and benign dystrophic calcifications to indeterminate focal asymmetries, architectural distortions, and masses. A combination of different modalities can assist a radiologist in reaching a logical conclusion to avoid unnecessary interventions. The aim of this review article was to provide a comprehensive literature on the various imaging appearances of fat necrosis in the breast. Although a purely benign entity, the imaging appearances on mammography, contrast-enhanced mammography, ultrasound, and magnetic resonance imaging can be quite misleading, especially in post-therapy breasts. The purpose is to provide a comprehensive and all-inclusive review on fat necrosis with a proposed algorithm allowing a systematic approach to diagnosis.

Abstract
The development of multifunctional biomaterials as both tissue regeneration and drug delivery devices is currently a major focus in biomedical research. Tannic Acid (TA), a naturally occurring plant polyphenol, displays unique medicinal abilities as an antioxidant, an antibiotic, and as an anticancer agent. TA has applications in biomaterials acting as a crosslinker in polymer hydrogels improving thermal stability and mechanical properties. We have developed injectable cell seeded collagen beads crosslinked with TA for breast reconstruction and anticancer activity following lumpectomy. This study determined the longevity of the bead implants by establishing a degradation time line and TA release profile in vivo. Beads crosslinked with 0.1% TA and 1% TA were compared to observe the differences in TA concentration on degradation and release. We found collagen/TA beads degrade at similar rates in vivo, yet are resistant to complete degradation after 16 weeks. TA is released over time in vivo through diffusion and cellular activity. Changes in mechanical properties in collagen/TA beads before implantation to after 8 weeks in vivo also indicate loss of TA over a longer period of time. Elastic moduli decreased uniformly in both 0.1% and 1% TA beads. This study establishes that collagen/TA materials can act as a drug delivery system, rapidly releasing TA within the first week following implantation. However, the beads retain TA long term allowing them to resist degradation and remain in situ acting as a cell scaffold and tissue filler. This confirms its potential use as an anticancer and minimally invasive breast reconstructive device following lumpectomy.

Abstract
BACKGROUND Oncoplastic breast-conserving surgery (O-BCS) involves removing the tumour in the breast and using plastic surgery techniques to reconstruct the breast. The adequacy of published evidence on the safety and efficacy of O-BCS for the treatment of breast cancer compared to other surgical options for breast cancer is still debatable. It is estimated that the local recurrence rate is similar to standard breast-conserving surgery (S-BCS) and also mastectomy, but the aesthetic and patient-reported outcomes may be improved with oncoplastic techniques. OBJECTIVES Our primary objective was to assess oncological control outcomes following O-BCS compared with other surgical options for women with breast cancer. Our secondary objective was to assess surgical complications, recall rates, need for further surgery to achieve adequate oncological resection, patient satisfaction through patient-reported outcomes, and cosmetic outcomes through objective measures or clinician-reported outcomes. SEARCH METHODS We searched the Cochrane Breast Cancer Group's Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (via OVID), Embase (via OVID), the World Health Organization's International Clinical Trials Registry Platform and ClinicalTrials.gov on 7 August 2020. We did not apply any language restrictions. SELECTION CRITERIA We selected randomised controlled trials (RCTs) and non-randomised comparative studies (cohort and case-control studies). Studies evaluated any O-BCS technique, including volume displacement techniques and partial breast volume replacement techniques compared to any other surgical treatment (partial resection or mastectomy) for the treatment of breast cancer. DATA COLLECTION AND ANALYSIS Four review authors performed data extraction and resolved disagreements. We used ROBINS-I to assess the risk of bias by outcome. We performed descriptive data analysis and meta-analysis and evaluated the quality of the evidence using GRADE criteria. The outcomes included local recurrence, breast cancer-specific disease-free survival, re-excision rates, complications, recall rates, and patient-reported outcome measures. MAIN RESULTS We included 78 non-randomised cohort studies evaluating 178,813 women. Overall, we assessed the risk of bias per outcome as being at serious risk of bias due to confounding; where studies adjusted for confounding, we deemed these at moderate risk. Comparison 1: oncoplastic breast-conserving surgery (O-BCS) versus standard-BCS (S-BCS) The evidence in the review found that O-BCS when compared to S-BCS, may make little or no difference to local recurrence; either when measured as local recurrence-free survival (hazard ratio (HR) 0.90, 95% confidence interval (CI) 0.61 to 1.34; 4 studies, 7600 participants; very low-certainty evidence) or local recurrence rate (HR 1.33, 95% CI 0.96 to 1.83; 4 studies, 2433 participants; low-certainty evidence), but the evidence is very uncertain due to most studies not controlling for confounding clinicopathological factors. O-BCS compared to S-BCS may make little to no difference to disease-free survival (HR 1.06, 95% CI 0.89 to 1.26; 7 studies, 5532 participants; low-certainty evidence). O-BCS may reduce the rate of re-excisions needed for oncological resection (risk ratio (RR) 0.76, 95% CI 0.69 to 0.85; 38 studies, 13,341 participants; very low-certainty evidence), but the evidence is very uncertain. O-BCS may increase the number of women who have at least one complication (RR 1.19, 95% CI 1.10 to 1.27; 20 studies, 118,005 participants; very low-certainty evidence) and increase the recall to biopsy rate (RR 2.39, 95% CI 1.67 to 3.42; 6 studies, 715 participants; low-certainty evidence). Meta-analysis was not possible when assessing patient-reported outcomes or cosmetic evaluation; in general, O-BCS reported a similar or more favourable result, however, the evidence is very uncertain due to risk of bias in the measurement methods. Comparison 2: oncoplastic breast-conserving surgery (O-BCS) versus mastectomy alone O-BCS may increase local recurrence-free survival compared to mastectomy but the evidence is very uncertain (HR 0.55, 95% CI 0.34 to 0.91; 2 studies, 4713 participants; very low-certainty evidence). The evidence is very uncertain about the effect of O-BCS on disease-free survival as there were only data from one study. O-BCS may reduce complications compared to mastectomy, but the evidence is very uncertain due to high risk of bias mainly resulting from confounding (RR 0.75, 95% CI 0.67 to 0.83; 4 studies, 4839 participants; very low-certainty evidence). Data on patient-reported outcome measures came from single studies; it was not possible to meta-analyse the data. Comparison 3: oncoplastic breast-conserving surgery (O-BCS) versus mastectomy with reconstruction O-BCS may make little or no difference to local recurrence-free survival (HR 1.37, 95% CI 0.72 to 2.62; 1 study, 3785 participants; very low-certainty evidence) or disease-free survival (HR 0.45, 95% CI 0.09 to 2.22; 1 study, 317 participants; very low-certainty evidence) when compared to mastectomy with reconstruction, but the evidence is very uncertain. O-BCS may reduce the complication rate compared to mastectomy with reconstruction (RR 0.49, 95% CI 0.45 to 0.54; 5 studies, 4973 participants; very low-certainty evidence) but the evidence is very uncertain due to high risk of bias from confounding and inconsistency of results. The evidence is very uncertain for patient-reported outcome measures and cosmetic evaluation. AUTHORS' CONCLUSIONS The evidence is very uncertain regarding oncological outcomes following O-BCS compared to S-BCS, though O-BCS has not been shown to be inferior. O-BCS may result in less need for a second re-excision surgery but may result in more complications and a greater recall rate than S-BCS. It seems that O-BCS may give better patient satisfaction and surgeon rating for the look of the breast, but the evidence for this is of poor quality, and due to lack of numerical data, it was not possible to pool the results of different studies. It seems O-BCS results in fewer complications compared with surgeries involving mastectomy. Based on this review, no certain conclusions can be made to help inform policymakers. The surgical decision for what operation to proceed with should be made jointly between clinician and patient after an appropriate discussion about the risks and benefits of O-BCS personalised to the patient, taking into account clinicopathological factors. This review highlighted the deficiency of well-conducted studies to evaluate efficacy, safety and patient-reported outcomes following O-BCS.

Porcine Acellular Dermal Matrix Increases Fat Survival Rate after Fat Grafting in Nude Mice. Aesthetic Plast Surg 2021; 45:2426-2436. [PMID: 33959783 PMCID: PMC8481189 DOI: 10.1007/s00266-021-02299-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Accepted: 04/10/2021] [Indexed: 11/05/2022]
Abstract
Background Autologous fat grafts have been widely in use for reconstruction, contour abnormalities, and cosmetic surgeries. However, the grafted fat one-year survival rate is unpredictable and always low (20%–80%). Standardizing the existing transplantation technology is difficult due to the limiting conditions. Scaffold materials or drugs are unsuitable to employ because of legal restrictions, complex production, and undetermined hazards. Therefore, a simpler and more effective approach to improve grafted fat survival rate is using commercial products as additives. Earlier studies proved that porcine acellular dermal matrix (PADM), a biomaterial clinically used for wound repair, could work as a scaffold for lipo-implantation. This study aimed at investigating the hitherto unclear effect of PADM on transplanted fat survival. Methods Thirty-two 8-week-old female nude mice were divided into two groups. Control mice received a 300 μl fat injection, while the PADM group mice were injected with a 300 μl PADM-fat mixture. After a 4-week treatment, fat weight and liquefaction ratio were assessed. Histological changes were quantified via hematoxylin & eosin (H&E) staining. Macrophage infiltration and vascular regeneration were revealed using an anti-CD34 antibody. Mouse and human mRNA expression levels were gauged via RNA-sequencing. On the third day post implantation, the mRNA expression levels of inflammatory genes Mcp-1 and Tnf-α were measured by qRT-PCR. Results The weight of surviving grafted fat did not differ between the control and the PADM group. However, adding PADM significantly decreased fat liquefaction. H&E-stained sections showed that PADM decreased fat necrosis, increased fat tissue regeneration, and raised CD34 levels in the regenerated tissue. RNA-sequencing showed that, compared to controls, fats from PADM-added group expressed more mouse-related mRNA but less human-related mRNA. The following GO and KEGG analysis showed that added PADM increased extracellular matrix (ECM) genes expression levels. The qRT-PCR showed that adding PADM increased Mcp-1 and Tnf-α mRNA expression levels. Conclusions In summary, PADM addition increased fat survival rate by reducing fat liquefaction through an increased macrophage infiltration, ECM regeneration, and revascularization. Therefore, PADM addition is a workable application in autologous fat grafting. No Level Assigned This journal requires that authors assign a level of evidence to each article.

Abstract
Many benign breast entities have a clinical and imaging presentation that can mimic breast cancer. The purpose of this review is to illustrate the wide spectrum of imaging features that can be associated with benign breast diseases with an emphasis on the suspicious imaging findings associated with these benign conditions that can mimic cancer. As radiologic-pathologic correlation can be particularly challenging in these cases, the radiologist’s familiarity with these benign entities and their imaging features is essential to ensure that a benign pathology result is accepted as concordant when appropriate and that a suitable management plan is formulated.

Abstract
Background In general, breast pain is one of the most common causes for referral to breast units; treatment-related breast pain is frequently seen in clinical practice but not well addressed in the literature. While our primary objective was to identify the incidence of persistent breast pain following breast-conserving surgery and possible risk factors, our secondary aim was to assess the possibility of using a breast ultrasound scan to detect parenchymal changes that can contribute to breast pain. Methods We have conducted a prospective study including patients who had wide local excision for primary breast cancer treatment between January 2017 and January 2019. Patients’ demographics, including age, BMI, breast volume, and tumour characteristics, were noted. All patients had a clinical assessment and were asked standard questions about their breast pain each visit; they also had an ultrasound scan of the breast and axilla 6 and 12 months after surgery to look for parenchymal changes. Results A total of 239 female breast cancer patients were included in our analysis. The mean age was 43.9 years, mean weight was 72.8 kg, mean BMI was 27.4 and mean breast volume was 1173 ml. In total, 38.5% had standard wide local excision, and 61.5% had oncoplastic resection; the mean specimen weight was 74.6 grams. All patients had adjuvant whole breast radiotherapy. We found that patients with younger age, larger breast size, high BMI, oncoplastic resections, and persistent parenchymal changes are associated with an increased incidence of postoperative breast pain while the type of axillary procedure and adjuvant chemotherapy had no significant effect. Conclusion Persistent postoperative breast pain was noted in 33% of our patients. We have also indicated that younger patients, patients with larger breast, those with high BMI, with preoperative breast pain, who had oncoplastic resections, and patients with persistent parenchymal changes, as fat necrosis and scarring, are associated more with persistent breast pain.

Abstract
Background Although fat necrosis is a minor postoperative complication after breast reconstruction, occasionally it mimics to tumor recurrence in patients with breast cancer. Therefore, the surgeon should distinguish between benign fat necrosis and true local recurrence. The authors evaluated the clinical characteristics of fat necrosis after breast reconstruction and investigated the natural course of fat necrosis. Methods Between 2007 and 2013, a total of 362 patients underwent breast reconstruction after partial or total mastectomy for breast cancer in Kyungpook National University Hospital. Clinicopathologic characteristics and the occurrence of fat necrosis were assessed during surveillance for 10 years of mean follow-up period. Results There were 42 cases (11.6%) of fat necrosis after breast reconstruction with partial or total mastectomy which were confirmed by needle or excision biopsy. The fat necrosis was resolved after a mean period of 45.9 months (SD, ± 42.1) and 26 cases (61.9%) of fat necrosis were almost completely resolved (less than 5 mm) during 10-year follow-up period. Conclusion Based on the natural course of fat necrosis, the fat necrosis after breast reconstruction can be only monitored, if pathologic confirmation was done. More than half of the cases will be resolved within 2–3 years. Supplementary Information The online version contains supplementary material available at 10.1186/s12885-021-07881-x.

Abstract
Breast cancer is the most commonly diagnosed cancer among women worldwide. Surgical removal of tumors is often necessary and many patients suffer complications due to subsequent breast reconstruction. A safe and effective breast reconstructive material is needed for patients recovering from surgical removal of small breast cancer tumors. Our lab has developed injectable collagen/tannic acid beads seeded with patient-derived preadipocytes for regeneration of healthy breast tissue in patients post-lumpectomy. Previous research indicates that the inclusion of tannic acid in the matrix imparts an anticancer property. This research seeks to determine the variables needed to control collagen/tannic acid bead diameter and seeded cell attachment, which are essential to proper bead implantation and function. We found that as tannic acid concentration increases within the beads, cell attachment decreases. Bead diameter is controlled by bead generator voltage, solution osmolality, the degree of cell attachment, and tannic acid concentrations. Higher voltages resulted in significant decrease in bead diameter. Collagen/tannic acid beads decreased in diameter when placed in solutions of increasing osmolality. Higher degrees of cell attachment across the surface of the beads were associated with a significant decrease in diameter. In beads made with high concentrations of tannic acid, bead diameter was found to decrease. Collagen/TA beads are a promising subdermal tissue regenerative matrix with anticancer activity as an alternative to simple lipofilling in breast reconstructive procedures. This study was conducted to better understand the properties of collagen/TA beads in order to improve injection efficacy and tissue regenerative activity.

Abstract
Plastic surgical principles are incorporated with breast conservation surgery (BCS) for cancer to improve aesthetic outcomes. In developing countries, average tumour size is larger at presentation resulting in larger resections often, including overlying skin. LD flap has been the workhorse of partial breast reconstruction. We present an easy and effective alternative to LD flap for carefully selected cases of outer quadrant breast tumours. We report 41 cases of local transposition flap from the lateral chest wall for oncoplastic restoration post BCS, performed between January 2016 and February 2020, at our institution. The median age was 49 years (28-63). Twenty-six patients underwent upfront surgery and 15 after neoadjuvant chemotherapy (NACT). The average pathological tumour size was 2.9 cm (median 2.7 and range 1.1-6) and 1.5 cm (median 1.8 and range 0-3.5) for upfront and post-NACT groups, respectively. The median volume of the resected specimen was 277.8 ml and 253.2 ml for upfront and post-NACT groups, respectively. Three patients (7.5%) had a microscopic positive margin requiring margin revision. Three (7.5%) patients had post-operative minor wound complications and were managed conservatively. At a median follow-up of 14 months (1-36), only 2/19 (10.5%) patients had clinical fat necrosis. Local transposition flap from the lateral chest wall based on dermal and subdermal plexus, carefully designed in selected patients, can be used effectively for the reconstruction of outer quadrant breast defects. It is easy to learn, offers good cosmetic outcome, avoids the morbidity and time of LD flap and saves LD flap for future use.

Abstract
OPINION STATEMENT Oncoplastic surgery (OPS) expands the indications and possibilities of breast-conserving surgery (BCS) by allowing for a wider cancer resection than lumpectomy. Ongoing investigation and reporting of OPS outcomes along with improvements in comprehensive training in breast surgical oncology will impact on awareness and lead to increased adoption of these techniques. Indications for OPS include concern about clear margins, poor tumor location (upper inner pole and lower quadrant), multifocality, need for skin excision, and poor candidacy for mastectomy and reconstruction. OPS has been proven to be oncological safe with comparable rates of complications, positive margins, and re-excisions with BCS. Additionally, OPS has a positive impact on the quality of life and self-esteem when compared with those patients that underwent BCT.

Abstract
INTRODUCTION This report details a case of a preseptal fat necrosis in a 55-year old female, following a revision endoscopic dacryocystorhinostomy (DCR). CASE DESCRIPTION Upon initial examination, significant right eyelid swelling, tenderness, and pain in the peritrochlear area, was observed. An overlying skin edema was noted in the supero-medial portion of the right upper eyelid. This edema was palpable, firm, and tender. Orbital computed tomography revealed heterogeneous infiltration including an ill-defined margin in the preseptal regions of the clinically evident location. Marked, soft tissue edema and thickening in the inner preseptal area were demonstrated through magnetic resonance images (MRI). An excision biopsy was required as the lesion did not respond to medical treatment. A necrosis of adipose tissue surrounded by abundant foamy macrophages and inflammatory infiltrates, was exposed. CONCLUSION This is an exceptionally rare case of orbital fat necrosis following a DCR. Four possible mechanisms for the development of fat necrosis are discussed.

Abstract
PURPOSE This study reports predictive dosimetric and physiologic factors for fat necrosis after stereotactic-partial breast irradiation (S-PBI). METHODS AND MATERIALS Seventy-five patients with ductal carcinoma-in situ or invasive nonlobular epithelial histologies stage 0, I, or II, with tumor size <3 cm were enrolled in a dose-escalation, phase I S-PBI trial between January 2011 and July 2015. Fat necrosis was evaluated clinically at each follow-up. Treatment data were extracted from the Multiplan Treatment Planning System (Cyberknife, Accuray). Univariate and stepwise logistic regression analyses were conducted to identify factors associated with palpable fat necrosis. RESULTS With a median follow-up of 61 months (range: 4.3-99.5 months), 11 patients experienced palpable fat necrosis, 5 cases of which were painful. The median time to development of fat necrosis was 12.7 months (range, 3-42 months). On univariate analyses, higher V32.5-47.5 Gy (P < .05) and larger breast volume (P < .01) were predictive of any fat necrosis; higher V35-50 Gy (P < .05), receiving 2 treatments on consecutive days (P = .02), and higher Dmax (P = .01) were predictive of painful fat necrosis. On multivariate analyses, breast volume larger than 1063 cm3 remained a predictive factor for any fat necrosis; receiving 2 treatments on consecutive days and higher V45 Gy were predictive of painful fat necrosis. Breast laterality, planning target volume (PTV), race, body mass index, diabetic status, and tobacco or drug use were not significantly associated with fat necrosis on univariate analysis. CONCLUSIONS Early-stage breast cancer patients treated with breast conserving surgery and S-PBI in our study had a fat necrosis rate comparable to other accelerated partial breast irradiation modalities, but S-PBI is less invasive. To reduce risk of painful fat necrosis, we recommend not delivering fractions on consecutive days; limiting V42.5 < 50 cm3, V45 < 20 cm3, V47.5 < 1 cm3, Dmax ≤ 48 Gy and PTV < 100 cm3 when feasible; and counseling patients about the increased risk for fat necrosis when constraints are not met and for those with breast volume >1000 cm3.

Abstract
Background Several studies have reported the use of acellular dermal matrix in breast reconstruction. However, the primary role of acellular dermal matrix in these studies was to support the implant; there are no reports on the use of acellular dermal matrix exclusively as volume replacement. Thus, we aimed to evaluate the safety and effectiveness of filling of the defect with acellular dermal matrix in oncoplastic breast-conserving surgery. Methods We prospectively recruited 120 adult breast cancer patients who were scheduled to undergo oncoplastic breast-conserving surgery with acellular dermal matrix filling from 2017 to 2018. Intraoperatively, diced human acellular dermal matrix measuring 3–5 mm was used on each side to fill in the excisional defect immediately. After 6 months, satisfaction of the patients and surgeons with overall and cosmetic outcomes was evaluated with a survey using a 10-point scale. Postoperative complications were assessed at 2 weeks and 6 months postoperatively. Results Of the 117 patients who were evaluated for their satisfaction, 94.0% were strongly satisfied with the cosmetic outcomes and 90.4% were strongly satisfied overall. Patient overall satisfaction scores were higher than surgeon satisfaction scores (p < 0.001). Of the 117 patients who underwent evaluation of complications 6 months postoperatively, six (5.1%) had hematoma and seven (6.0%) had seroma. The overall reoperation rate due to complications was 8.5%. Only two patients needed acellular dermal matrix removal due to hematoma and inflammation. Conclusion Oncoplastic breast-conserving surgery with acellular dermal matrix filling of defects can be performed safely with high cosmetic satisfaction.

Abstract
BACKGROUND Oncoplastic breast conserving surgery had been challenged to achieve both of local control and the cosmetic appearance of preserved breast. We developed the lateral thoracoaxillar dermal-fat flap (LTDF) as an oncoplastic procedure to fill the defect of breast-conserving surgery in 1999. METHODS A total of 2338 breast cancer patients underwent surgery from January, 2000 to December, 2017. Mastectomy was performed in 706 patients (30%), and breast conservative surgery (BCS) was performed in 1634 patients (70%). The LTDF was adopted in 487/1634 (30%) of BCS cases to fill the large defect left by partial resection. we divided all patients into 3 groups: breast total mastectomy (BT group), the breast partial resection (BP) with LTDF (LTDF group), and Bp without LTDF (BP group) and compared the clinical characteristics, and recurrence rate. RESULTS The Indications for LTDF increased up to 40% in 2010, while they decreased to 20%-30% in the most recent period, in accordance with the frequency of breast reconstruction increased. Patients who underwent BP + LTDF (LTDF group) included significantly higher proportions of stage II diseases and cases treated by neoadjuvant chemotherapy than those in BP or BT groups.. We found no marked difference of local recurrence and distant metastases between the LTDF and Bp groups. However, the rate of distant metastasis was significantly higher in BT group than in the Bp or LTDF group. Concerning the complications of LTDF, we experienced a few complications of Grade 3-4 requiring surgical management, namely one case of dislocation of the LTDF, three cases of bleeding, and five cases each of skin necrosis and fat necrosis. CONCLUSIONS We reported satisfying long-term outcomes of 487 cases treated by LTDF. LTDF is a suitable oncoplastic technique for BCS.
