Background:. Acellular dermal matrices (ADMs) entered the market in the early 2000s and their use has increased thereafter. Several retrospective cohort studies and single surgeon series reported benefits with the use of ADMs. However, robust evidence supporting these advantages is lacking. There is the need to define the role for ADMs in implant-based breast reconstruction (IBBR) after mastectomy. Methods:. A panel of world-renowned breast specialists was convened to evaluate evidence, express personal viewpoints, and establish recommendation for the use of ADMs for subpectoral one-/two-stage IBBR (compared with no ADM use) for adult women undergoing mastectomy for breast cancer treatment or risk reduction using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Results:. Based on the voting outcome, the following recommendation emerged as a consensus statement: the panel members suggest subpectoral one- or two-stage IBBR either with ADMs or without ADMs for adult women undergoing mastectomy for breast cancer treatment or risk reduction (with very low certainty of evidence). Conclusions:. The systematic review has revealed a very low certainty of evidence for most of the important outcomes in ADM-assisted IBBR and the absence of standard tools for evaluating clinical outcomes. Forty-five percent of panel members expressed a conditional recommendation either in favor of or against the use of ADMs in subpectoral one- or two-stages IBBR for adult women undergoing mastectomy for breast cancer treatment or risk reduction. Future subgroup analyses could help identify relevant clinical and pathological factors to select patients for whom one technique could be preferable to another.

Objective: Nerve injury is one of the most common complications of varicose vein surgery and is a frequent cause for litigation but its incidence following lower limb arterial surgery has not been well documented. This study was undertaken to determine the incidence of nerve injury following lower limb arterial surgery. This was addressed in relation to long saphenous or femoral vein harvesting, or re-operative surgery.Materials and Methods: A total of one hundred patients who had undergone lower limb arterial reconstruction in the previous five years were invited to participate in this study. Seventy-eight patients responded, of which 44 patients (66 operated legs) agreed to participate. They underwent neurological assessment of the lower limbs.Results: 66.7% of limbs had objective evidence of sensory deficit following lower limb arterial surgery but none had motor deficit. Redo surgery or superficial femoral vein harvest had no influence on the incidence of nerve injury. Below knee incisions had a higher incidence of nerve injury than other approaches. Long saphenous vein harvest significantly increased the rate of nerve injury.Conclusions: There is a high incidence of sensory nerve damage following lower limb arterial surgery. In the present climate of increasing litigation it is important to know the likely incidence of post-operative nerve damage so that patients can be counselled appropriately during the process of obtaining informed consent.

Clinical trials have demonstrated conclusively the non-inferiority of breast-conserving surgery followed by breast radiation therapy (BCT) compared with mastectomy for the treatment of early-stage invasive breast cancer (BC). The definition of the required surgical margin to ensure adequate removal of the cancer by BCT to obtain an acceptable low local recurrence (LR) rate remains controversial. Meta-analyses published by Houssami et al. in 2010 and 2014 demonstrated significantly lower LR rates for patients with a negative margin compared with those with positive (ink on tumour) or close (defined as ≤1 mm or ≤2 mm) margins. Neither meta-analysis addressed whether 'no ink on tumour' was adequate to define a negative margin because of a lack of data. Nevertheless, in 2014, the Society of Surgical Oncology (SSO) and the American Society for Radiation Oncology (ASTRO) with advice from pathologists reviewed these data together and published guidelines recommending that a margin of 'no ink on tumour' was sufficient to define a clear margin in BCT. Subsequently, clinical practice has varied with some national and international bodies endorsing 'no ink on tumour', whilst others have recommended a ≥1 mm margin as acceptable margins for BCT. A more recent meta-analysis conducted by Bundred and colleagues in 2022 did have sufficient data to compare 'no ink on tumour' and 1 mm and concluded that 1 mm rather than 'no ink on tumour', should be used as a minimum negative margin, and recommended that international guidelines be revised. The current review presents a balanced assessment of the evidence relating margin width and local recurrence after BCT. This review concludes that guidelines should consider re-defining a negative margin as ≥1 mm rather than 'no ink on tumour' in the context of BCT, recognising there will be variation to tailor therapy for any individual patient situation to ensure optimal patient care., Competing Interests: Declaration of competing interest None All authors declare that no financial and personal relationships with other people or organizations that could inappropriately influence (bias) this work., (Copyright © 2024 The Author(s).

Background: Breast cancer is the most common cancer worldwide, with remarkable advances in early diagnosis, systemic treatments, and surgical techniques. Robotic nipple-sparing mastectomy has been trialled; however, the complication rates, surgical outcomes, and oncological safety of this approach remain obscure., Methods: A systematic search of the literature was conducted from conception until September 2022. Studies examining complications and operative variables where robotic nipple-sparing mastectomy was compared with conventional nipple-sparing mastectomy were included. Primary study outcomes were complications (Clavien-Dindo grade III complications, skin or nipple necrosis, seroma, haematoma, infection, implant loss, and wound dehiscence) and oncological safety (recurrence and positive margins). The secondary outcomes included operative variables, length of stay, cost-effectiveness, learning curve, and aesthetic outcome., Results: A total of seven studies of overall fair quality, involving 1674 patients, were included in the systematic review and meta-analysis. Grade 3 complications were reduced in robotic nipple-sparing mastectomy without statistical significance (OR 0.60 (95 per cent c.i. 0.35 to 1.05)). Nipple necrosis was significantly reduced in robotic nipple-sparing mastectomy (OR 0.54 (95 per cent c.i. 0.30 to 0.96); P = 0.03; I2 = 15 per cent). Operating time (mean difference +58.81 min (95 per cent c.i. +28.19 to +89.44 min); P = 0.0002) and length of stay (mean difference +1.23 days (95 per cent c.i. +0.64 to +1.81 days); P < 0.0001) were significantly increased in robotic nipple-sparing mastectomy, whereas the opposite was true for blood loss (mean difference -53.18 ml (95 per cent c.i. -71.78 to -34.58 ml); P < 0.0001)., Conclusion: Whilst still in its infancy, robotic breast surgery may become a viable option in breast surgery. Nonetheless, the oncological safety of this approach requires robust assessment., (© The Author(s) 2023. Published by Oxford University Press on behalf of BJS Society Ltd.)

Background: Chronic pain after breast cancer surgery affects up to 60% of patients. Evidence supports the fact that pain outwith the surgical site is a significant issue. This systematic review and meta-analysis sought to evaluate the prevalence of non-surgical site pain (NSSP) in women after breast cancer surgery at 6 months post-operatively., Methods: Adult women with a confirmed breast cancer diagnosis who had undergone breast cancer surgery were identified. The outcome pursued was pain outwith the surgical site measured on either NRS/VRS or VAS rating scale. CENTRAL, Embase, PubMed, MEDLINE, CINAHL, PsycInfo, Web of Science, and Scopus were searched to identify studies that examined NSSP after breast cancer surgery at 6 months. Data were gathered via pre-piloted Excel forms and analysed both quantitively and qualitatively. Meta-analysis was carried out using a random-effects model to assess risk difference with 95% confidence interval (CI)., Results: A total of sixteen studies were identified for inclusion. Eleven studies failed to provide sufficient data and consequently were analysed qualitatively. Five studies were adequate for quantitative analysis, including a total of 995 patients. Meta-analysis identified a risk difference of 18% (95% CI: 5-31%) between patients who had breast cancer surgery and a reference, however, this is low-quality evidence., Conclusion: This review has highlighted that breast cancer surgery increases the risk of pain outwith the surgical site postoperatively. It was additionally identified that NSSP data are often gathered in research yet rarely presented in results or highlighted as a primary outcome. As the quality of evidence was low, research specifying NSSP as a primary outcome is required to provide more certainty., Competing Interests: Patrice Forget received fees from Grunenthal for an educational activity not related to any product.

Background: Volume replacement using chest wall perforator flaps (CWPFs) is a promising technique to reduce mastectomy rates without sacrificing function or aesthetics. Owing to limited availability of the technique, only a minority of patients currently have access to CWPF procedures., Methods: An international web-based survey was disseminated through social media, dedicated webpages, and national and international societies for breast surgery. The survey explored surgeons' attitudes towards CWPFs and their perceived training needs., Results: Of 619 respondents, 88.4 per cent agreed that CWPF surgery was desirable, with one-third offering it and performing a median of 10 (i.q.r. 5-15) procedures annually. They were more likely to be senior (OR 1.35, 95 per cent c.i. 1.18 to 1.55; P < 0.001), with formal oncoplastic training (OR 4.80, 3.09 to 7.48; P < 0.001), and working in larger units (OR 1.18, 1.03 to 1.35; P = 0.018) with a free-flap (OR 1.62, 1.06 to 2.48; P = 0.025) or CWPF (OR 3.02, 1.87 to 4.89; P < 0.001) service available. In cluster and latent class analysis, none showed high cohesion with performance of CWPF surgery., Conclusion: There is a discrepancy between perceived importance and availability of CWPF surgery, indicating that optimal training is needed., (© The Author(s) 2023.

Introduction: Patients are increasingly turning to other sources for their health information. Social media has become mainstream, and the easy access to online communities, health professionals, and shared experiences of other patients has made social media a place where many patients turn to., Methods: In this qualitative report, 2 patients who have had breast cancer describe the reasons why they use social media, what they perceive the advantages and disadvantages are, and what the impact of social media has been through their cancer treatment and beyond., Results: The reasons why patients turn to social media are varied. These can include information gathering, peer support, shared experiences, and advocacy. There appear to be advantages and disadvantages; however, overall, the impact seems to be a positive one when used judiciously., Discussion: It is clear that social media has a role to play in healthcare, whether by providing meaningful social connections, delivery of information, or psychological support. Healthcare professionals perhaps should consider the importance of social media in their practice., Competing Interests: The authors have no conflicts of interest to declare., (© 2023 S.

Background: Early detection along with improved locoregional and systemic therapies have decreased breast cancer mortality and allowed for the clinical implementation of breast conserving surgical options, in turn reducing the clinical and psychosocial impact of mastectomy. To what extend this has been successfully conveyed through social media for breast cancer awareness, has not been previously investigated., Methods: This study presents a content and social network cross-sectional descriptive study of Twitter and Google trends data worldwide from platform launch (2006 and 2004 respectively) until May 15th, 2022, in agreement with the STROBE guidelines. Tweets associated with the hashtags #Breastcancer, #Breastsurgery, #Oncoplasticsurgery, #Mastectomy, #Breastreconstruction, #Breastconservingsurgery were licensed and downloaded through the Vincitas and Tweetbinder online platforms. Associated available demographics, namely username, biography, location, date and language of post, were extracted from the Twitter dataset while interest percentage, location and language of search were extracted from the Google trends dataset., Results: A total of 390111 unique tweets were generated by 127284 unique users, with 2 users engaging with all six hashtags. Original tweets constituted on average 39.1% [Min 30.7% to max 47.2%] of the total. Hashtag frequency increased on Twitter for all six searches during October, the breast-cancer awareness month, but not on Google trends. Cancer survivors engaged much more often with the hashtag #Breastcancer and #Mastectomy, whereas #Breastsurgery, #Oncoplasticsurgery, #Breastconservingsurgery, #Breastreconstruction were mostly used by health professionals., Conclusion: In this large qualitative and quantitative dataset, geo-temporal oscillations on Twitter and Google trends for hashtags relevant with breast cancer provide preliminary insights on information flow and user engagement. Understanding the effective use of social media platforms may provide the niche for disseminating evidence and promoting education on the surgical options of patients with breast cancer., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2023 The Authors.

Background: Female breast cancer (BC) is the most diagnosed cancer and the leading cause of malignancy-related death worldwide. With the widespread utilisation of the Internet, social media has presented an invaluable yet underemployed tool in the context of BC medical information dissemination, support hub formation, and patient empowerment., Summary: In this narrative review, we explore the untapped potential of social media in this context, caveats, and future directions that may aid in formulating a new era of patient led, in addition to patient-centred care., Key Messages: Social media represents a powerful tool with significant potential to enable the seeking and sharing of BC-related information, and enhance patient education, communication, engagement, and empowerment. However, its use is associated with a number of limitations, including confidentiality and addiction issues, excessive and inaccurate information, and a possibility of jeopardising the patient-doctor relationship. Further research is needed to shed more light on this topic., Competing Interests: No conflict within the scope of the present work. Advisory Board for Resitu AB.

Globally, BC is the most frequently diagnosed cancer in women. The aim of this study was to identify novel secreted biomarkers that may indicate progression to high-grade BC malignancies and therefore predict metastatic potential. A total of 33 studies of breast cancer and 78 of other malignancies were screened via a systematic review for eligibility, yielding 26 datasets, 8 breast cancer secretome datasets, and 18 of other cancers that were included in the comparative secretome analysis. Sequential bioinformatic analysis using online resources enabled the identification of enriched GO&#95;terms, overlapping clusters, and pathway reconstruction. This study identified putative predictors of IDC grade progression and their association with breast cancer patient mortality outcomes, namely, HSPG2, ACTG1, and LAMA5 as biomarkers of in silico pathway prediction, offering a putative approach by which the abovementioned proteins may mediate their effects, enabling disease progression. This study also identified ITGB1, FBN1, and THBS1 as putative pan-cancer detection biomarkers. The present study highlights novel, putative secretome biomarkers that may provide insight into the tumor biology and could inform clinical decision making in the context of IDC management in a non-invasive manner.

Background: Sentinel Lymph Node Biopsy (SLNB) is used to stage the axilla, but there is limited data in patients with prior ipsilateral breast cancer. This study compares redo-SLNB (reSLNB) and Axillary node sample (ANS) in this sub-cohort of patients., Materials and Methods: This is a retrospective study looking at patients with a new ipsilateral primary or recurrence with history of breast-conserving surgery. Planned and performed surgery, patient demographics and previous treatments were recorded. Node positivity and success rate of reSLNB was analyzed., Results: A total of 86 patients were identified that had mastectomy for ipsilateral recurrent disease with radiologically negative axilla. Out of the 48 that had reSLNB, 35(72.9%) were successful. Nineteen percent of the reSLNB had positive axillae and 20% of the ANS patients. reSLNB success rate was significantly lower amongst patients with previous axillary surgery (P = .014) and previous positive nodes(P = .001)., Conclusion: reSLNB should be considered to restage the axilla in patients with previous history of ipsilateral cancer especially that there is growing evidence showing good identification rate., (Copyright © 2022 The Authors.

Background: Radiotherapy after breast surgery decreases locoregional recurrence and improves survival. This is not without risks from radiation exposure and could have implications in clinical practice. Our study investigates the correlation between tumour location and radiation dose to the heart., Methods: Left-sided breast cancer patients who had radiotherapy at Aberdeen Royal Infirmary in 2010 were identified. Tumour location was established from notes and imaging. Radiotherapy planning scans were reviewed, and cardiac doses calculated. The mean cardiac dose, maximum dose and volume of the heart in the field, along with V5-V40, were determined., Results: 40 patients had mastectomies and 118 breast conserving surgery. The median percentage of the heart in the field and the Interquartile Range was 0.59% (0.03-1.74) for all patients, with the highest for lower inner quadrant (LIQ) tumours 1.20% (0.29-2.40), followed by mastectomy 0.94% (0.02-1.82). The mean heart dose showed a higher median for mastectomies 1.59 Gy (1.00-1.94), followed by LIQ tumours 1.58 Gy (1.31-2.28), with an overall median of 1.42 Gy (1.13-1.95). The median percentage of the heart in the field, the mean cardiac dose and V5-V30 did not reach statistical significance, however, V40 and the maximum dose did., Conclusions: The benefits of radiotherapy after breast cancer surgery are established, but with potential harm from cardiac exposure. Our cohort showed higher radiation exposure to the heart in patients with LIQ tumours and mastectomies but reached significance only for V40 and maximum dose. This highlights tumour location as a potentially important risk factor for cardiac exposure with breast radiotherapy.

Chyle leak following oncological breast and axillary surgery is a rare complication with small number of reported cases in the literature and little formal guidance regarding management. We present a review of the current literature and further related guidance from other specialties, along with suggested strategies for identification, diagnosis and management of this uncommon but potentially significant complication., Competing Interests: Declaration of Competing Interest There are no financial or other relationships in regard to this submission that might lead to a conflict of interest.

Aims: Pleomorphic lobular carcinoma in situ (PLCIS) is a relatively newly described pathological lesion that is distinguished from classical LCIS by its large pleomorphic nuclei. The lesion is uncommon and its appropriate management has been debated. The aim of this study is to review data from a large series of PLCIS to examine its natural history in order to guide management plans., Materials and Methods: Comprehensive pathology data were collected from two cohorts; one from a UK multicentre audit and the other a series of PLCIS cases identified from within the GLACIER study cohort. 179 cases were identified of whom 176 had enough data for analysis., Results: Out of these 176 cases, 130 had invasive disease associated with PLCIS, the majority being of lobular type (classical and/or pleomorphic). A high incidence of histological grade 2 and 3 invasive cancers was noted with a predominance of ER positive and HER-2 negative malignancy. When PLCIS was the most significant finding on diagnostic biopsy the upgrade to invasive disease on excision was 31.8%, which is higher than pooled data for classical LCIS and DCIS., Conclusion: The older age at presentation, high grade of upgrade to invasive cancer, common association with higher grade tumours suggest that PLCIS is an aggressive form of insitu disease. These findings support the view that PLCIS is a more aggressive form of lobular in situ neoplasia and supports the tendency to treat akin to DCIS., (Copyright © 2017 Elsevier Ltd.

Background: Pleomorphic Lobular Carcinoma in Situ (PLCIS) is a pathological variant of Lobular Carcinoma in Situ (LCIS) with distinct features. Since first described over a decade ago there are only few papers published about this condition., Methods: Medline and Pubmed based literature overview was done with the aim of describing the different histopathological, radiological and clinical features of this pathological entity to highlight the different clinicopathological presentations and modalities of treatment described., Results: PLCIS has different biological features when compared to LCIS. It is more likely to be associated with invasive disease and the immuno-histochemical profile shows it is less likely to be ER and PR positive with higher positivity of HER2, Ki-67and p53. It has been suggested that PLCIS should be treated more aggressively than LCIS and surgically excised in similar fashion to DCIS., Conclusion: PLCIS is a more aggressive variant of LCIS that needs to be managed differently. Surgical excision with clear margins is advised. Further adjuvant treatments have been described in the literature with little evidence to support their use., (Copyright © 2013 Elsevier Ltd.

Inflammatory breast cancer (IBC) is a rare entity that makes up 1-3% of breast cancers. As the diagnosis of IBC is mainly clinical, for the inexperienced the clinical appearance can mimic mastitis leading to diagnostic delay and it is often associated with a poor prognosis. Very few cases of bilateral IBC are reported in the literature, all of which have been synchronous. We report an unusual case of bilateral metachronous IBC each with complete clinico-pathological response after treatment with neoadjuvant chemotherapy and surgery on both occasions.

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used worldwide, and their complications in the upper gastrointestinal tract are well described in the literature and well known to clinicians. However, complications in the large bowel are being increasingly recognized and reported. This review aims to address the different aspects of NSAIDs-associated colopathy., Methods: This is a review article addressing NSAIDs colopathy. A Medline-based search was performed for articles published between 1950 and 2008 on this condition. Keywords detailed were colonic disease, ulcers, strictures and/or diaphragm strictures. Only articles in the English language were considered., Results: The articles identified included letters to the editors, case reports, case series, review articles and few original research papers. The review was structured in a narrative style in different sections addressing pathophysiology, clinical presentation and management., Conclusions: NSAIDs colopathy is a rare benign condition. Current evidence only suggests an association with prolonged use of the NSAIDs, however, there are no studies to support the direct causation. The presentation is non-specific, and the commonest findings on endoscopy are ulceration and diaphragm-like strictures. The importance of identifying this condition is to prevent complications and also to be able to differentiate it from other conditions such as inflammatory bowel disease (IBD) and malignancy.

Objective: This study investigates whether methylene blue (MB), patent blue V (PBV), and indigo carmine (IDC) commonly used in sentinel node biopsy cause DNA damage to breast epithelial cells in vitro., Methods: MCF-7 and HB-2 cells were exposed for 5 minutes to the above dyes at the same concentrations used in clinical practice. Following exposure, the comet assay was performed to detect DNA damage. The enzyme, Fapy-DNA glycosylase (FpG) was incorporated to enable the detection of additional oxidative damage., Results: Both PBV and MB stimulated DNA strand breaks in both MCF-7 and HB2 cell lines (P < 0.05). Levels were elevated over 3-fold (P < 0.05) in MCF-7 and HB2 cells treated with 2.5% PBV and 1% MB, compared with untreated control cells. In contrast, IDC did not stimulate DNA strand break damage at clinically relevant concentrations in either cell line. Addition of Fapy-DNA glycosylase enzyme also revealed significantly (P < 0.05) increased levels of oxidative DNA lesions (ODL) in MCF-7 cells treated with PBV (17.6% ODL) compared with control cells (5.9% ODL)., Conclusions: This study shows, for the first time, that certain dyes (MB and PBV) commonly used in SLNB have genotoxic effects on breast cells at clinically relevant concentrations in vitro. In vivo studies are now warranted to assess and minimize DNA damage caused by these dyes during SLNB.

Neoadjuvant chemotherapy (NACT) is a useful approach in the treatment of many breast cancers. One of the main advantages of NACT is the possibility of breast conservation surgery in patients who would otherwise require a mastectomy. Most literature on NACT focuses on the effectiveness of different chemotherapy regimen and subsequent mastectomy rates. There is little guidance in the literature on aspects of individual patient management and decision making during NACT. This paper considers practical management advice where NACT is considered and adopted.

Background: Vascular injuries following cholecystectomy are a known entity though the incidence is low. More frequently we are seeing cases of right hepatic artery pseudo aneurysm post cholecystectomy after the advent of the laparoscopic approach., Methods: We report a case of multiple right hepatic artery aneurysms as a complication of cholecystectomy in a 71-year-old patient., Results: The diagnosis was confirmed by angiogram, and the patient was treated successfully with coil embolisation., Conclusion: Though it is a rare complication, early diagnosis and treatment of postoperative pseudo aneurysm is essential to prevent life threatening bleeding.

Hepatocellular carcinoma is the most common primary tumour of the liver. Metastasis is frequent in these aggressive tumours and is commonly to the lungs, regional lymph nodes, or bone. Metastasis as a discrete subcutaneous nodule has not been described before. We report a case of hepatocellular carcinoma with a solitary subcutaneous metastatic deposit identified 18 months after the initial hepatic surgery.

This is a case report of an 85-year old patient who presented with abdominal pain, nausea and vomiting associated with altered liver function test. The plain X-rays and CT scan showed pneumobilia with an ectopic gallstone. The patient was diagnosed with Bouveret syndrome and managed surgically. The report is followed by a discussion about Bouveret syndrome.
