Postoperative Prophylactic Antibiotic Use in Breast Reduction Mammoplasty: A Single Centre Retrospective Cohort Study

Introduction: Breast reduction mammoplasty (BRM) is a common procedure performed by plastic surgeons treating patients with hypermastia. It is customary to give preoperative prophylactic intravenous antibiotics for BRM, followed by several days of postoperative prophylactic oral antibiotics, despite the lack of evidence of their effectiveness in preventing surgical site infections (SSIs). The purpose of this study is to determine if the addition of prophylactic postoperative antibiotics is more effective in preventing SSIs in comparison to a single dose of preoperative prophylactic antibiotics in BRM. Methods: A retrospective analysis of 124 elective BRM cases by a single senior plastic surgeon was completed. Two study groups were formed based on the location of surgery and each group was assigned a different antibiotic regimen. The first antibiotic regimen consisted of a single preoperative intravenous dose of antibiotics (group 1), while the second regimen consisted of a preoperative intravenous dose followed by a 5-day course of oral antibiotics (group 2). Results: Overall SSI rate was 5.6%. Infection rate in group 1 was 8.1% in comparison to 3.2% for group 2 (P value .44). Overall, the incidence of complications was 29.0%; 38.7% in group 1 and 19.4% in group 2 (P value .03). Complications consisted of 35 cases of delayed wound healing, 7 SSIs and 2 hematomas requiring evacuation. Conclusion: Study results demonstrated that the use of postoperative prophylactic antibiotics for BRM had no significant effect on the rate of SSIs.

Imaging the dense breast

The sensitivity of mammography reduces as breast density increases, which impacts breast screening and locoregional staging in breast cancer. Supplementary imaging with other modalities can offer improved cancer detection, but this often comes at the cost of more false positives. Magnetic resonance imaging and contrast-enhanced mammography, which assess tumour enhancement following contrast administration, are more sensitive than digital breast tomosynthesis and ultrasound, which predominantly rely on the assessment of tumour morphology.

Nipple-Sparing Mastectomy and Adequate Margins for Patients With Ductal Carcinoma In Situ

BACKGROUND

For patients with ductal carcinoma in situ (DCIS) undergoing breast conservation surgery (BCS), guidelines advise a margin width of at least 2 mm, with studies demonstrating decreased recurrence risk compared to narrower margins. However, limited data exist establishing if this margin is appropriate in mastectomies, and specifically for nipple-sparing mastectomy (NSM). Consequently, we evaluated the margins of DCIS patients undergoing NSM and resulting oncologic outcomes.

METHODS

A single-institution retrospective review was performed in patients with DCIS or DCIS with microinvasion (DCIS + MI) undergoing NSM from April 2010 to December 2021. Patient and tumor characteristics, margin status, treatment, and outcomes information were collected. The association between margins and local-regional (LRR) and distant recurrence (DR) were examined.

RESULTS

161 patients were included, comprising 284 NSM (164 therapeutic, 120 prophylactic). 153 patients had DCIS and 8 had DCIS + MI. Most patients had hormone sensitive, 123 (76.4%), and nuclear grade 2, 72 (44.7%), disease. In total, 35 (21.7%) patients had positive or <2 mm margins. Of these, 21 (60%) involved the anterior margin. At a median follow-up of 45 months (range 0-151), 2.5% (n = 4) had a LRR and .6% (n = 1) had a DR. Of patients with a recurrence, only 2 had positive or <2 mm margins, 1 had received endocrine therapy, and none received adjuvant radiation.

DISCUSSION

No specific margin status was found to correlate with recurrence for patients with DCIS or DCIS + MI undergoing NSM, with an altogether low recurrence risk. Overall, this suggests that recommended DCIS margins in BCS doesn't necessarily apply in NSM, where margins of <2 mm may be acceptable.

Navigating changes: A qualitative study exploring the health-related quality of life of breast cancer survivors during the coronavirus disease 2019 pandemic

AIMS

To explore the impact of the coronavirus disease 2019 pandemic on the health-related quality of life (HRQoL) of breast cancer survivors.

DESIGN

We utilized a qualitative descriptive approach to facilitate interviews among 25 participants, all of whom are survivors of breast cancer and have received treatment in Hong Kong within the preceding 3 years.

METHODS

Content analysis was performed to understand how patients' HRQoL views and experiences changed during coronavirus disease 2019 pandemic.

RESULTS

The results included six themes delineating the impact of the coronavirus disease 2019 pandemic: (i) survivor sensitivities in pandemic times, (ii) coping and conditioning in pandemic times, (iii) transforming work and home dynamics in pandemic times, (iv) cognitive resilience and adaptation to the COVID-19 protective measures, (v) social resilience in pandemic times and (vi) healthcare adaptation and coping in pandemic times.

CONCLUSION

This study provides insights into the experiences and challenges of breast cancer survivors during the coronavirus disease 2019 pandemic. Some survivors had new physical and psychological symptoms, including fear and anxiety, isolation, pain, lymphoedema and burnout, which potentially have long-term impact upon HRQoL.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

This study highlights the unique challenges faced by breast cancer survivors during the coronavirus disease 2019 pandemic, including accessing healthcare services and the impact of social isolation. Healthcare providers should consider the holistic needs of breast cancer survivors in the provision of health care and develop supportive interventions, including telehealth services and online support groups, to address these challenges and improve their HRQoL.

IMPACT

Surgery aimed at treating breast cancer or reducing its risk generally influences the appearance of breast areas and donor sites. The continuing effects of these changes on body image and HRQoL are well-reported, although studies have ineffectively examined the initial experiences of women regarding their postoperative appearance, particularly during the pandemic.

REPORTING METHOD

The checklist of consolidated criteria for reporting qualitative research (COREQ) was utilized.

PATIENT OR PUBLIC CONTRIBUTION

A small selection on breast cancer survivors contributed to the design of this study, in particular the content of the semi-structured interviews.

Use of artificial intelligence in breast surgery: a narrative review

Background and Objective

We have witnessed tremendous advances in artificial intelligence (AI) technologies. Breast surgery, a subspecialty of general surgery, has notably benefited from AI technologies. This review aims to evaluate how AI has been integrated into breast surgery practices, to assess its effectiveness in improving surgical outcomes and operational efficiency, and to identify potential areas for future research and application.

Methods

Two authors independently conducted a comprehensive search of PubMed, Google Scholar, EMBASE, and Cochrane CENTRAL databases from January 1, 1950, to September 4, 2023, employing keywords pertinent to AI in conjunction with breast surgery or cancer. The search focused on English language publications, where relevance was determined through meticulous screening of titles, abstracts, and full-texts, followed by an additional review of references within these articles. The review covered a range of studies illustrating the applications of AI in breast surgery encompassing lesion diagnosis to postoperative follow-up. Publications focusing specifically on breast reconstruction were excluded.

Key Content and Findings

AI models have preoperative, intraoperative, and postoperative applications in the field of breast surgery. Using breast imaging scans and patient data, AI models have been designed to predict the risk of breast cancer and determine the need for breast cancer surgery. In addition, using breast imaging scans and histopathological slides, models were used for detecting, classifying, segmenting, grading, and staging breast tumors. Preoperative applications included patient education and the display of expected aesthetic outcomes. Models were also designed to provide intraoperative assistance for precise tumor resection and margin status assessment. As well, AI was used to predict postoperative complications, survival, and cancer recurrence.

Conclusions

Extra research is required to move AI models from the experimental stage to actual implementation in healthcare. With the rapid evolution of AI, further applications are expected in the coming years including direct performance of breast surgery. Breast surgeons should be updated with the advances in AI applications in breast surgery to provide the best care for their patients.

Delayed Diagnosis of Inflammatory Breast Cancer Presenting as Acute Mastitis in a Patient One Month Postpartum

Inflammatory breast cancer (IBC) is a rare yet aggressive form of invasive ductal carcinoma, with a poor prognosis and decreased 5-year survival rates. Characteristic findings for IBC include rapid onset of breast edema, peau d'orange appearance, and involvement of the breast skin. Additionally, diagnosis is confirmed with a skin punch biopsy. With such nonspecific features, IBC can be mistaken for benign etiologies, causing delays in diagnosis and treatment. This patient is a 44-year-old woman presenting with left breast swelling while concurrently breastfeeding. Following antibiotic treatment but no symptom resolution, the patient was referred out for further follow-up. Despite multiple imaging studies, suggesting benign findings, clinical suspicion prompted continued evaluation and finally diagnosis of triple-negative inflammatory breast cancer with distant metastases. Further awareness of the presentation of IBC and its mimicking of other disease processes such as mastitis is paramount to earlier detection and improved outcomes in future patients.

Avoiding unnecessary sentinel lymph node biopsy with the use of superparamagnetic iron oxide mapping agents (Magtrace®) in breast surgery

BACKGROUND

Superparamagnetic iron oxide (SPIO) (Magtrace®) is a non-radioactive liquid tracer that can stay in the sentinel lymph nodes for 30 days. Injection of SPIO at time of primary breast surgery where upfront sentinel lymph node biopsy (SLNB) is not immediately indicated allows for a return to theatre if pathology then identifies invasive disease. SLNB is associated with paraesthesia, pain, seroma formation and lymphoedema risk. Hence, our study aims to assess the use of SPIO to avoid upfront SLNB in breast surgery for ductal carcinoma in situ (DCIS) and prophylaxis.

METHODS

Retrospective single-centre study of consecutive patients who underwent injection of SPIO tracer at time of primary breast surgery to avoid upfront SLNB at Chris O'Brien Lifehouse, Sydney, NSW, Australia over a 10-month period.

RESULTS

SPIO was injected 38 times, with 34 at time of mastectomy and four cases at time of wide local excision. The indication for surgery was DCIS in 18 cases, risk reduction in 17 cases and other indications in three patients. Six cases (15.8%) required delayed SLNB (D-SLNB) due to the finding of invasive disease on post-operative histopathology. All patients who underwent D-SLNB had nodes successfully localized with SPIO.

CONCLUSION

In our cohort, 84.2% of cases were able to avoid upfront SLNB, and hence avoid the associated complications of SLNB. SPIO injection was successful in localizing the SLN in all cases at time of surgery for D-SLNB. This technique was safe with few associated complications.

Opioid prescribing practices in breast oncologic surgery-A retrospective cohort study

BACKGROUND

In breast oncologic surgery, 75% of patients receive a postoperative opioid prescription at discharge, and 10%-20% will develop persistent opioid use. To inform future institutional guidelines, the objective of this study was to determine baseline opioid prescribing patterns in a single high-volume, referral-based breast center. We hypothesized that opioid prescribing practices varied between procedures and operating surgeons.

METHODS

A retrospective analysis of all women undergoing breast cancer surgery between January and December 2019. Opioid prescriptions at discharge were converted to morphine milligram equivalents (MME). The primary outcome of interest was MME prescribed at discharge. Multiple linear regression was used to identify factors independently associated with MME prescribed.

RESULTS

392 patients met inclusion criteria; 68.3% underwent partial mastectomy. Median age was 61 (interquartile range [IQR] 51-70). Median MME prescribed at discharge was 112.5 (IQR 75-150); 83.9% of patients were prescribed co-analgesia. The prescriber was a trainee in 37.7% of cases. 15 patients (3.8%) required opioid renewal. On multivariate analysis, axillary procedure was associated with increased MME (ß = 17, 95% CI 5.5-28 and ß = 32, 95% CI 17-47, for sentinel node and axillary dissection, respectively). However, the factor with the greatest impact on MME was operating surgeon (ß = 72, 95% CI 58-87). Residents prescribed less MME compared to attending surgeons (ß = 11, 95% CI -22; -0.06).

CONCLUSION

In a tertiary care center, the operating surgeon had the greatest influence on opioid prescribing practices, and trainees tended to prescribe less MME. These findings support the need for a standardized approach to optimize prescribing and reduce opioid-related harms after oncologic breast surgery.

Anatomic Areas of Lipoframing in Breast Surgery

Breast lipoframing is a concept in breast surgery that encompasses the often-overlooked aspects of the mammary glands, such as the surrounding structures and adipose tissue within the thorax. By acknowledging the interplay between these components and recognizing the need for their simultaneous treatment, breast lipoframing aims to optimize surgical aesthetic outcomes. This article proposes a comprehensive definition of the surrounding mammary fat tissue by delineating the specific areas of the breast involved in the lipoframing technique. It presents a retrospective analysis of 554 female patients, revealing only one case of seroma and three cases of hematoma. Furthermore, we explore the application of liposuction as a means to effectively treat these areas and achieve superior results.

The effect of music on the operating surgeon: a pilot randomized crossover trial (the MOSART study)

OBJECTIVE

The experience of stress is common among surgeons while working in the operating theatre (OT). Understanding and finding ways to mitigate this stress is important for optimizing surgical quality and maintaining clinician wellbeing. In this pilot study, we tested the feasibility and reported the outcomes of measuring the effect of background music on intra-operative surgeon stress in the clinical environment.

METHODS

The effect of Music on the Operating Surgeon: A pilot Randomized crossover Trial (the MOSART study) was conducted over a 9-month period in a single-centre. Vascular and general surgeons acting as primary operators (POs) performing elective, general anaesthetic operations were included. The intervention was surgeon-selected music, and the control was the absence of music. Outcome measures were feasibility (recruitment rate, practicability, and completeness of data), heart rate variability (HRV) indices, the Six-Item State-Trait Anxiety Inventory (STAI-6), and the Surgical Task-load Index (SURG-TLX).

RESULTS

Five POs performed 74 eligible randomized cases. The protocol was well tolerated, and no cases were abandoned. Data was incomplete in 8% of cases. The overall mean (SD) operative SURG-TLX score was 48 (±22). Mean HR increased and RMSSD decreased significantly from baseline, suggesting reduced parasympathetic activity while operating. The presence of intra-operative music was not found to affect the psychological or physiological outcomes.

CONCLUSIONS

A music interventional study of this nature is feasible in the operating theatre environment, though no difference was found between in the music and non-music conditions. Follow-up research in a simulated environment with intensive physiological monitoring could be considered.

Patterns of completion axillary dissection for patients with cT1-2N0 breast cancer undergoing total mastectomy with positive sentinel lymph nodes

BACKGROUND AND OBJECTIVES

The ACOSOGZ0011 trial found that overall survival (OS) for patients with 1-2 positive nodes undergoing sentinel lymph node biopsy-alone (SLNB) was noninferior to completion axillary lymph node dissection (ALND), but excluded patients undergoing mastectomy. Our study examined patterns of ALND and its relationship with OS for SLNB-positive patients undergoing mastectomy.

METHODS

The National Cancer Database was queried (2010-2017) for patients with cT1-2N0 breast cancer undergoing mastectomy with positive sentinel lymph nodes. Clinical data were compared.

RESULTS

Of 20 001 patients, 11 574 (57.9%) underwent SLNB + ALND, and 8427 (42.1%) had SLNB-alone. The SLNB + ALND group had more positive nodes (mean 2.6 vs. 1.3, p < 0.001) and more frequently received nodal radiation (33.4% vs. 28.9%, p < 0.001). Patients diagnosed in later years were less likely to undergo ALND (2010: reference; 2017: odds ratio: 0.29, 95% confidence interval [CI]: 0.25-0.33, p < 0.001). ALND (hazard ratio [HR]: 0.97, 95% CI: 0.89-1.06, p = 0.49) and nodal radiation (HR: 0.92, 95% CI: 0.83-1.02, p = 1.06) were not independently associated with OS. Propensity-score matched 5-year OS was similar (SLNB + ALND: 90.9% vs. SLNB-alone: 90.3%, p = 0.65).

CONCLUSION

For patients undergoing mastectomy for cT1-2N0 breast cancer with positive SLNB, SLNB-alone was common and increased over time. Axillary radiation was not routinely delivered in the SLNB-alone group. Completion ALND and nodal radiation were not associated with improved survival.

The Relationship Between Breast Density and Breast Cancer Surgical Outcomes: A Systematic Review

This study aims to investigate the relationship between mammographic breast density and the surgical outcomes of breast cancer. PubMed, SCOPUS, Web of Science, Science Direct, and the Wiley Library were systematically searched for relevant literature. Rayyan QRCI was employed throughout this comprehensive process. Our results included ten studies with a total of 5017 women diagnosed with breast cancer. The follow-up duration ranged from 1 year to 15.1 years. Eight out of the twelve included studies reported that low mammographic breast density was significantly associated with no local recurrence, metachronous contralateral breast cancer, and fewer challenges in the preoperative and intraoperative phases. On the other hand, four studies reported that mammographic breast density is not linked to disease recurrence, survival, re-excision, or an incomplete clinical and pathological response. There is a significant association between low mammographic breast density and reduced challenges in the preoperative and intraoperative phases, as well as no local recurrence and fewer mastectomy cases. However, the link between mammographic breast density and disease recurrence, survival, re-excision, and incomplete clinical and pathological response is less clear, with some studies reporting no significant association. The findings suggest that mammographic breast density may play a role in certain aspects of breast cancer outcomes, but further research is needed to fully understand its impact.

Pre-emptive paracetamol reduces intra-operative opioid use in patients undergoing day-case oncologic breast surgery

Minimization of intra-operative opioid use is an area of ongoing research interest with several potential benefits to the patient. Pre-emptive analgesia, defined as the administration of an analgesic before surgery to prevent establishment of central sensitization of pain, is one avenue that has been explored to achieve this. A retrospective observational study was undertaken to examine the effect of pre-emptive paracetamol on intra-operative opioid requirements. The medical and operative data of 156 patients who underwent day-case wide local excision and sentinel lymph node biopsy with and without regional block surgery at our center between October 2019 and May 2022 was carried out. Data were collected on demographics, total intra-operative and immediate post-operative opioid consumption. 57 patients did not receive pre-emptive paracetamol while 90 did. Baseline characteristics were similar. Our results showed a statistically significant reduction in morphine (p <0.029) and remifentanil (p <0.007) consumption in patients who received a regional block and pre-emptive paracetamol. Those who did not receive a regional block and were given pre-emptive paracetamol had a decrease in OxyNorm (p <0.022) requirements. A combination of general anesthesia (GA), regional block and pre-emptive paracetamol reduced intra-operative consumption of Fentanyl, OxyNorm, diclofenac, dexketoprofen, and clonidine (P <0.001) when compared to just GA alone. Use of pre-emptive paracetamol in reduction of intra-operative opioid requirements showed promising results but larger studies may strengthen the evidence for this association. A multimodal analgesic approach that utilizes pre-emptive paracetamol can be a viable method to decrease intra-operative of analgesic requirements.

Radioactive seed localization is a safe and effective tool for breast cancer surgery: an evaluation of over 25,000 cases

Radioactive seed localization (RSL) provides a precise and efficient method for removing non-palpable breast lesions. It has proven to be a valuable addition to breast surgery, improving perioperative logistics and patient satisfaction. This retrospective review examines the lessons learned from a high-volume cancer center's RSL program after 10 years of practice and over 25 000 cases. We provide an updated model for assessing the patient's radiation dose from RSL seed implantation and demonstrate the safety of RSL to staff members. Additionally, we emphasize the importance of various aspects of presurgical evaluation, surgical techniques, post-surgical management, and regulatory compliance for a successful RSL program. Notably, the program has reduced radiation exposure for patients and medical staff.

Efficiency Assessment of Breast Clinics for Patients Under 35: A Comparative Analysis of Targeted Models in a University Hospital

Despite the higher incidence of breast cancer in older age groups, it remains pertinent not to overlook breast cancer occurrence in those aged 35 years and below. Recent transitions toward targeted under-35 clinics in England aim to enhance efficiency and meet referral standards. Three models were planned, and we assessed the efficiency of each model. This study, conducted for five months within a single National Health Service (NHS) trust, analyzed data from the following clinics: the General One-Stop Clinic, the Under 35 One-Stop Clinic with ultrasound services (USS), and the Under 35 Clinic without USS services. Of the 300 patients recruited (100 consecutive patients from each clinic), 94.3% were female. The average age at presentation was 27.53 years. The most frequently encountered age group was between 26 and 30 years, and the majority of patients had palpable lumps (78, 51.6%). Out of 300 patients who attended the clinics, 151 had USS, and of these, 15 biopsies were performed. Fibroadenomas (32, 21.2%) and cysts (22, 14.6%) were the most common radiological findings. We found that more breast imaging was being undertaken for under-35 patients who attended the general one-stop clinics compared to the specific under-35 clinics. Targeted breast clinics for individuals 35 years and below offer an effective approach in terms of resource allocation and meeting cancer targets.

A Novel Surgical Technique for Gynecomastia: Air-Assisted Minimally Invasive Surgery With Single Axillary Incision

BACKGROUND

Gynecomastia is a benign condition that develops due to the proliferation of breast tissue in men. Surgical excision is the most effective treatment method. Minimally invasive techniques can be used to avoid visible scarring. We evaluated the efficacy and safety of air-assisted subcutaneous mastectomy in the treatment of gynecomastia.

PATIENT AND METHODS

10 patients with gynecomastia underwent air-assisted subcutaneous mastectomy and liposuction through a single axillary incision, between June 2022 and February 2023. Demographic and clinical data of the patients, duration of surgery, and complications were recorded. The satisfaction levels of the patients regarding physical appearance, mental status, and social environment were measured. The body Q questionnaire was performed preoperatively and in the postoperative third month.

RESULTS

The median age was 26 (range, 18-54). Surgical excision was measured as a median of 69 gr (range, 41-177), and liposuction volume was measured as a median of 210 ccs (range, 63-400). The median operation time was 50 minutes (range, 21-60) for excision and 21 minutes (range, 20-75) for liposuction. Body, chest, and nipples related appearance satisfaction levels were measured preoperatively as a median of 44 (range, 36.5-52), 31 (range, 27.5-39), and 51.5 (range, 21-69.8) points vs postoperatively as 92 (range, 92-100), 93 (range, 93-94.8) and 90 (range, 90-100) points, respectively. The patients had a median follow-up of 6 months (range, 3-11). No complications were observed during the follow-up period.

CONCLUSION

Air-assisted subcutaneous mastectomy and liposuction is a feasible technique that may provide good cosmetic outcomes by avoiding anterior chest wall scarring.

Delayed complications from polyacrylamide gel breast fillers: a case report

In the late nineties, polyacrylamide gel (PAAG) gained popularity in China as a soft tissue filler for breast augmentation and contouring, but was banned 10 years later due to the increasing incidence of complications. We report a case of PAAG complication that occurred 20 years after the initial injection, where the patient had significant unilateral breast swelling and an intracapsular lesion. Surgical removal of the breast filler and immediate breast reconstruction was successfully performed, and histology confirmed a benign breast lesion. These findings highlight the importance of clinical awareness of PAAG breast filler complications.

Racial disparities in surgical outcomes after mastectomy in 223 000 female breast cancer patients: a retrospective cohort study

BACKGROUND

Breast cancer mortality and treatment differ across racial groups. It remains unclear whether such disparities are also reflected in perioperative outcomes of breast cancer patients undergoing mastectomy.

STUDY DESIGN

The authors reviewed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2008-2021) to identify female patients who underwent mastectomy for oncological purposes. The outcomes were stratified by five racial groups (white, Black/African American, Asian, American Indian/Alaska Native, and Native Hawaiian/Pacific Islander) and included 30-day mortality, reoperation, readmission, surgical and medical complications, and non-home discharge.

RESULTS

The study population included 222 947 patients, 68% ( n =151 522) of whom were white, 11% ( n =23 987) Black/African American, 5% ( n =11 217) Asian, 0.5% ( n =1198) American Indian/Alaska Native, and 0.5% ( n =1018) Native Hawaiian/Pacific Islander. While 136 690 (61%) patients underwent partial mastectomy, 54 490 (24%) and 31 767 (14%) women received simple and radical mastectomy, respectively. Overall, adverse events occurred in 17 222 (7.7%) patients, the largest portion of which were surgical complications ( n =7246; 3.3%). Multivariable analysis revealed that being of Asian race was protective against perioperative complications [odds ratio (OR)=0.71; P <0.001], whereas American Indian/Alaska Native women were most vulnerable to the complication occurrence (OR=1.41; P <0.001). Black/African American patients had a significantly lower risk of medical (OR=0.59; P <0.001) and surgical complications (OR=0.60; P <0.001) after partial and radical mastectomy, respectively, their likelihood of readmission (OR=1.14; P =0.045) following partial mastectomy was significantly increased.

CONCLUSION

The authors identified American Indian/Alaska Native women as particularly vulnerable to complications following mastectomy. Asian patients experienced the lowest rate of complications in the perioperative period. The authors' analyses revealed comparable confounder-adjusted outcomes following partial and complete mastectomy between Black and white races. Their findings call for care equalization in the field of breast cancer surgery.

Paget's Presentation of High-Grade Ductal Carcinoma In Situ (DCIS) in a Very Young Female With Breast Cancer 2 (BRCA2) Mutation

This is a case of a previously healthy 29-year-old female with erythema and skin excoriations of the left breast nipple-areolar complex (NAC). After a repeat trial and failure of topical hydrocortisone, a diagnostic mammogram and nipple biopsy revealed Paget's disease (PD) of the nipple with ductal carcinoma in situ (DCIS). A subsequent genetic analysis found a breast cancer 2 (BRCA2) gene mutation. Treatment consisted of a left breast skin-sparing simple mastectomy with sentinel lymph node (SLN) biopsy and immediate tissue expander placement for implant reconstruction. Further management involved right breast short-interval surveillance with annual mammography and magnetic resonance imaging (MRI) with the possibility of prophylactic surgery along with oophorectomy after childbearing.

Redefining the Axillary Aesthetic: Surgical Management of Axillary Tissue Hypertrophy

Background and Objectives: Axillary tissue hypertrophy consists of ectopic breast tissue and occurs in up to six percent of women. Women complain of pain, interference with activity, and dissatisfaction with appearance. While it is recommended that accessory breast tissue be removed via surgical excision, there is lack of consensus on the best technique for the surgical management of axillary tissue hypertrophy. In this study, the senior authors (BC and NT) review outcomes and complications as they pertain to the surgical treatment of axillary tissue hypertrophy and axillary contouring. Materials and Methods: A retrospective review of all patients (n = 35), from two separate institutions, who presented with axillary tissue hypertrophy between December 2019 and August 2021 was conducted. All patients underwent a technique that included direct crescentic dermato-lipectomy and glandular excision with axillary crease obliteration. Tissue was sent for histological analysis after removal. During a six-month follow-up period, all patient outcomes were recorded. Results: The authors treated 35 women with axillary tissue hypertrophy. All patients complained of aesthetic deformity with significant discomfort leading to the desire for surgery. Histologically, all specimens contained benign breast and adipose tissue. Hypertrophic scarring, seroma, and axillary cording were noted complications. Conclusions: Detailed is the surgical management and optimal technique that can be used to treat both adipose and fibroglandular axillary tissue hypertrophy while simultaneously providing a favorable axillary aesthetic.

Impact of Primary Breast Surgery on Overall Survival of Patients With De Novo Metastatic Breast Cancer: A Systematic Review and Meta-Analysis

BACKGROUND

Breast surgery in cases of de novo metastatic breast cancer (MBC) is associated with improved outcomes in retrospective studies, although the results of randomized controlled trials (RCTs) are conflicting. We aimed to investigate whether surgery in this context prolongs patient survival.

METHODS

We performed a systematic review of the literature to identify RCTs comparing surgery of primary breast cancer to no surgery in patients with de novo MBC. Cochrane Library, Embase, Medline (OVID), and Web of Science were searched with latest update in July 2023, while conference proceedings were manually searched. Data concerning patient and tumor characteristics, as well as outcomes, were extracted. A meta-analysis with random effects models was performed considering heterogeneity between trials.

RESULTS

Overall, 3255 entries were identified and 5 RCTs fulfilled all inclusion criteria, which had enrolled 1381 patients. The overall estimation in the intention-to-treat population showed no benefit for patients who had surgical excision of the primary breast tumor (HR = 0.93; 95% CI, 0.76-1.14). No subgroups in terms of receptor status or patterns of metastasis seemed to benefit from surgery, except for younger/premenopausal patients (HR = 0.74, 95% CI, 0.58-0.94). Breast surgery was associated with improved local progression-free survival (HR = 0.37, 95% CI, 0.19-0.74).

CONCLUSION

Surgery of the primary tumor in patients with de novo MBC does not prolong survival, except possibly in younger/premenopausal patients. Breast surgery should be offered within the context of well-designed clinical trials examining the issue.

Dermatofibrosarcoma protuberans of the breast in pregnancy

Dermatofibrosarcoma Protuberans (DFSP) is a rare, locally aggressive fibroblastic mesenchymal neoplasm, typically derived from the dermis, with the intramammary subtype being seen infrequently. We present a case of a 40-year-old woman whom was diagnosed with an intramammary DFSP during pregnancy, whom underwent successful surgical management during her second trimester. Our case demonstrates the importance of increased clinical awareness in the diagnosis and treatment of breast DFSP with careful multidisciplinary consideration.

Multiple Thoracic Wall Blocks for Awake Breast Surgery: A Case Report

Awake breast surgeries under nerve blocks have been a challenge for anaesthesiologists, and different block combinations have been used for surgery under sedation. Thoracic paravertebral block (TPVB) was thought to be sufficient alone for surgical anaesthesia of the breast. We performed a combination of TPVB, pectoralis nerve I block, and serratus anterior plane block for awake breast surgery in an elderly patient with serious comorbidities. Surgical anaesthesia was achieved, excluding skin incision. Any regional anaesthesia technique alone is not sufficient; rather, multiple thoracic wall blocks are needed for surgical anaesthesia of the breast.

Physician Characteristics Associated With Opioid Prescribing After Same-Day Breast Surgery in Ontario, Canada: A Population-Based Cohort Study

Background and Objectives

Opioid overprescribing in patients undergoing breast surgery is a concern, as evidence suggests that minimal or no opioid is needed to manage pain. We sought to describe characteristics of opioid prescribers and determine associations between prescriber's characteristics and high opioid prescribing within 7 days of same-day breast surgery.

Methods

Patients ≥18 years of age who underwent same-day breast surgery in Ontario, Canada from 2012 to 2020 were identified and linked to prescriber data. The primary outcome was current high opioid prescribing defined as >75th percentile of the mean oral morphine equivalents (OME; milligrams). Prescriber characteristics including age, sex, specialty, years in practice, practice setting, and history of high (>75th percentile) opioid prescribing in the previous year were captured. Associations between prescriber characteristics and the primary outcome were estimated in modified Poisson regression models.

Results

The final cohort contained 56,434 patients, 3469 unique prescribers, and 58,656 prescriptions. Over half (1971/3469; 57%) of prescribers wrote ≥1 prescription that was >75th percentile of mean OME of 180 mg, of which 50% were family practice physicians. Adjusted mean OMEs prescribed varied by specialty with family practice specialties prescribing the highest mean OME (614 ± 38 mg) compared to surgical specialties (general surgery [165 ± 9 mg], plastic surgery [198 ± 10 mg], surgical oncology [154 ± 14 mg]). Whereas 73% of first and 31% of second prescriptions were provided by general surgery physicians, family practice physicians provided 2% of first and 51% of second prescriptions. Prescriber characteristics associated with a higher likelihood of high current opioid prescribing were family practice (risk ratio [RR], 1.56; 95% confidence interval [CI], 1.35-1.79 compared to general surgery), larger community practice setting (RR, 1.34; 95% CI, 1.05-1.71 compared to urban), and a previous high opioid prescribing behavior (RR, 2.28; 95% CI, 2.06-2.52).

Conclusions

While most studies examine surgeon opioid prescribing, our data suggest that other specialties contribute to opioid overprescribing in surgical patients and identify characteristics of physicians likely to overprescribe.

Efficacy of Electronic Reminders in Increasing the Enhanced Recovery After Surgery Protocol Use During Major Breast Surgery: Prospective Cohort Study

BACKGROUND

Enhanced recovery after surgery (ERAS) protocols are patient-centered, evidence-based guidelines for peri-, intra-, and postoperative management of surgical candidates that aim to decrease operative complications and facilitate recovery after surgery. Anesthesia providers can use these protocols to guide decision-making and standardize aspects of their anesthetic plan in the operating room.

OBJECTIVE

Research across multiple disciplines has demonstrated that clinical decision support systems have the potential to improve protocol adherence by reminding providers about departmental policies and protocols via notifications. There remains a gap in the literature about whether clinical decision support systems can improve patient outcomes by improving anesthesia providers' adherence to protocols. Our hypothesis is that the implementation of an electronic notification system to anesthesia providers the day prior to scheduled breast surgeries will increase the use of the already existing but underused ERAS protocols.

METHODS

This was a single-center prospective cohort study conducted between October 2017 and August 2018 at an urban academic medical center. After obtaining approval from the institutional review board, anesthesia providers assigned to major breast surgery cases were identified. Patient data were collected pre- and postimplementation of an electronic notification system that sent the anesthesia providers an email reminder of the ERAS breast protocol the night before scheduled surgeries. Each patient's record was then reviewed to assess the frequency of adherence to the various ERAS protocol elements.

RESULTS

Implementation of an electronic notification significantly improved overall protocol adherence and several preoperative markers of ERAS protocol adherence. Protocol adherence increased from 16% (n=14) to 44% (n=44; P<.001), preoperative administration of oral gabapentin (600 mg) increased from 13% (n=11) to 43% (n=43; P<.001), and oral celebrex (400 mg) use increased from 16% (n=14) to 35% (n=35; P=.006). There were no statistically significant differences in the use of scopolamine transdermal patch (P=.05), ketamine (P=.35), and oral acetaminophen (P=.31) between the groups. Secondary outcomes such as intraoperative and postoperative morphine equivalent administered, postanesthesia care unit length of stay, postoperative pain scores, and incidence of postoperative nausea and vomiting did not show statistical significance.

CONCLUSIONS

This study examines whether sending automated notifications to anesthesia providers increases the use of ERAS protocols in a single academic medical center. Our analysis exhibited statistically significant increases in overall protocol adherence but failed to show significant differences in secondary outcome measures. Despite the lack of a statistically significant difference in secondary postoperative outcomes, our analysis contributes to the limited literature on the relationship between using push notifications and clinical decision support in guiding perioperative decision-making. A variety of techniques can be implemented, including technological solutions such as automated notifications to providers, to improve awareness and adherence to ERAS protocols.

Relationship between the change in tumour-infiltrating lymphocyte level and residual tumour after neoadjuvant chemotherapy in patients with locally advanced breast cancer

To evaluate the tumour-infiltrating lymphocyte (TIL) rates in breast tissue before and after neoadjuvant chemotherapy (NAC) and their impact on survival, eighty-four patients with locally advanced breast cancer (LABC) were assessed. Pre- and post-NAC TIL levels were determined using biopsy and surgical specimens, respectively. The median TIL rate was significantly different before (17.5%) and after (5%) NAC. Pre- and postoperative Ki-67 index, molecular subtype, pre- and post-NAC TIL concentration, and preoperative residual-cancer-burden TIL were significantly associated with pathological complete response (pCR). Specifically, higher pre-NAC TIL levels were associated with higher pCR rates. Postoperative Ki-67 index and pCR, and postoperative Ki-67 index were significant predictors of disease-free (DFS) and overall survival, respectively. The independent prognostic factors for DFS were postoperative Ki-67 score (hazard ratio [HR]: 6.16; p = 0.012), post-NAC TIL score (HR: 0.42; P = 0.041), and pCR (HR: 0.10; P = 0.038). Our study confirms that higher pre-NAC and lower postoperative TIL levels may be surrogate factors for longer DFS, and postoperative TIL rate may predict post-NAC pCR in patients with LABC.

Oncoplastic surgery for breast cancer: Global perspectives and trends

Oncoplastic surgery (OPS) is a form of breast conservation that combines definitive oncologic resection with optimal aesthetic outcomes. Various definitions exist, with most focusing on volume displacement techniques to close the lumpectomy defect and redistribute the remaining breast volume over the preserved breast. Although its oncologic safety has been well demonstrated, uptake into practice varies globally. This article details the definition, safety, training opportunities, and practice patterns of OPS on a global scale.

Use of artificial intelligence to identify patients to be assessed in a breast clinic on 2-week wait: a retrospective cohort study

Background

The number of urgent referrals from primary care to specialist one stop breast clinics continues to rise beyond the capacity of the 2-week wait service. This study aims to use artificial intelligence (AI) to identify patients with new breast symptoms requiring a biopsy to identify those who should be prioritised for urgent breast clinic assessment.

Methods

Data were collected retrospectively for patients attending one stop triple assessment breast clinic at Broomfield hospital between 1 June and 1 October 2021. PHP machine learning software was used to run AI on the data to identify patients who had a core biopsy in clinic.

Results

A total of 794 cases were referred to one stop breast clinic for new breast symptoms-37 male (4.6%) and 757 female (95.3%). The average age of the patients included was 43.2 years. Five hundred thirty-six patients (67.5%) presented with a breast lump, 180 (22.7%) with breast pain, 61 (7.7%) with changes to shape or skin and 13 (1.6%) with a lump identified by their general practitioner. The patients who had a biopsy were of increased age [52.8 (SD 17.9) vs. 44.1 (SD 16.8), P<0.001], and had previous mammogram [n=21, (31.8%) vs. n=148 (20.3%), P 0.03], previous benign breast disease [n=9 (13.6%) vs. n=23 (3.1%), P<0.001], and increased use of HRT [n=13 (19.7%) vs. n=53 (6.4%), P<0.001]. The sensitivity and specificity of AI with neural network algorithms were 84% and 90%, respectively.

Conclusion

AI was very effective at predicting the presenting symptoms that are likely to result in biopsy and can therefore be used to identify patients who need to be seen urgently in breast clinic.

Metastasis-directed therapy for oligometastases in breast cancer

The concept of oligometastases was first proposed to describe a disease state between localized cancer and extensive metastasis. After the emergence of variations in the definition of oligometastasis, in April 2020 the European Society for Radiotherapy and Oncology and the European Organization for Research and Treatment of Cancer defined oligometastases as the presence of one to five metastatic lesions that can be safely treated. However, the pathogenesis of oligometastases remains unknown, and it is uncertain which patients will benefit from metastasis-directed therapy. Breast cancer with oligometastases is generally managed with systemic therapy. Retrospective studies have suggested that the addition of metastasis-directed therapy, such as surgery, radiofrequency ablation and stereotactic body radiation therapy, may increase overall survival in breast cancer patients with oligometastases, but as yet there have been no prospective studies. Phase II trials of stereotactic body radiation therapy or fractionated irradiation for oligometastases of breast cancer have demonstrated impressive rates of local control and overall survival. Although the efficacy of stereotactic body radiation therapy in the SABR-COMET was largely anticipated, it is noteworthy that only 18% of the patient population had breast cancer. For this reason, various trials were planned or are being conducted globally to investigate the efficacy of metastasis-directed therapy for oligometastases of breast cancer. Metastasis-directed therapy for oligometastases has been shown to be effective, and stereotactic body radiation therapy and other therapies are commonly used internationally and are considered to be safe. However, the efficacy of metastasis-directed therapy for oligometastases has not yet been proven. The results of future clinical trials are thus eagerly awaited.

Radiation-induced angiosarcoma of the breast: a case report

Introduction

Breast angiosarcoma is a rare, aggressive tumour affecting adult women. It can occur in two forms, primary form and secondary forms or radiation-induced breast angiosarcoma affecting patients with history of breast or chest radiotherapy.

Case presentation

The authors report a new case of breast angiosarcoma in 52-year-old women, with history of invasive ductal carcinoma, and reporting a discoloration of her breast skin. The patient did undergo a mastectomy of right breast and adjuvant chemotherapy.

Conclusion/discussion

Surgery with total excision associated or not to adjuvant chemotherapy remains the treatment of choice in breast angiosarcoma.

Prediction of negative axillary node clearance by sentinel node-positive to total node ratio: a retrospective cohort study

Introduction

Increasing evidence suggests that de-escalation of axillary surgery is safe, without significantly impacting patient outcome. Obtaining positive lymph nodes at a sentinel lymph node biopsy (SNB) can guide decisions toward the requirement of axillary nodal clearance (ANC). However, methods to predict how many further nodes will be positive are not available. This study investigates the feasibility of predicting the likelihood of a negative ANC based on the ratio between positive nodes and the total number of lymph nodes excised at SNB.

Methods

Retrospective data from January 2017 to March 2022 was collected from electronic medical records. Patients with oestrogen receptor (ER) positive and HER2 negative receptor disease were included in the study. ER-negative and HER2-positive disease was excluded, alongside patients who had chemotherapy before ANC.

Results

Of 102 patients, 58.8% (n=60) had no macrometastasis at ANC. On average, 2.76 lymph nodes were removed at SNB. A higher SNB ratio of positive to total nodes [OR 11.09 (CI 95% 2.33-52.72), P=0.002] had a significant association with positive nodes during ANC. SNB ratio less than or equal to 0.33 (1/3) had a specificity of 79.2% in identifying cases that later had a negative completion ANC, with a 95.8% specificity of no further upgrade of nodal staging.

Conclusion

A low SNB ratio of less than 0.33 (1/3) has a high specificity in excluding the upgradation of nodal staging on completion of ANC, with a false-negative rate of less than 5%. This may be used to identify patients with a low risk of axillary metastasis, who can avoid ANC.

The clinical impact of pectoral nerve block in an 'enhanced recovery after surgery' program in breast surgery

Background: Pectoral nerve block (PECS) is increasingly performed in breast surgery. Aim: The study evaluated the clinical impact of these blocks in the postoperative course. Patients & methods: In this case-control study, patients undergoing breast surgery with 'enhanced recovery after surgery' pathways were divided into group 1 (57 patients) in whom PECS was performed before general anesthesia, and group 2 (57 patients) in whom only general anesthesia was effected. Results: Postoperative opioid consumption (p < 0.002), pain at 32 h after surgery (p < 0.005) and the length of stay (p < 0.003) were significantly lower in group 1. Conclusion: Reducing opioid consumption and pain after surgery, PECS could favor a faster recovery with a reduction in length of stay, ensuring a higher turnover of patients undergoing breast surgery.

Evaluation of the Efficacy of Pectoral Nerve-2 Block (PECS 2) in Breast Cancer Surgery

This study aimed to evaluate the efficacy of the pectoral nerves interfacial plane block (PECS II) in breast cancer surgery focusing on postoperative pain management and patient satisfaction. A prospective study was conducted, including 200 patients scheduled for breast cancer surgery. The participants were randomly assigned to the PECS II block and control groups. The PECS II block group received a preoperative interfascial plane block, while the control group received standard analgesia. Postoperative pain scores at 4 h intervals for the first 3 postoperative days, as well as opioid consumption and patient-reported satisfaction, were measured and compared between both groups. The PECS II block group demonstrated significantly lower postoperative pain scores at all measured time points (p < 0.001). Additionally, the PECS II block group showed reduced opioid consumption (p < 0.001), reported higher levels of patient satisfaction compared to the control group, and had a notably shorter stay in the postoperative care unit (p < 0.001). Integrating the PECS block with general anesthesia in breast cancer surgeries enhances pain management, reduces opioid use, and shorten postanesthesia care unit stay. The evident benefits suggest PECS as a potential standard in breast surgeries. Future research should further investigate its long-term impacts and broader applications.

Extensively infarcted breast cancer

This is a case of a tumour that appeared largely unviable after near complete infarction. The lesion presented as a regular shaped mass with cystic appearance lacking definitive malignant radiological signs. Together with the initial non-diagnostic histological result, this could have easily led to a missed diagnosis of cancer.

Effects of Perioperative Hypothermia on Extubation, Recovery Time, and Postoperative Shivering in Breast Surgery

Women undergoing breast surgery seem to be under the risk for hypothermia (central body temperature <36°) due to the uncertainty caused by the preoperative preparation time and the variety of operations, leading to neglect of warming precautions. The study examines the perioperative hypothermia (PH) in breast surgery and the relationships between the depth of decrease in body temperature and individual or clinical variables. This prospective, cross-sectional, observational study includes 120 female patients 18-65 years of age who were given general anesthesia for breast surgery. The incidence of hypothermia was 68.1%. The given patients were discriminated as body temperature <36°, hypothermia was significantly related with lower weight, body mass index, American Society of Anesthesiology (ASA) score, baseline body temperatures, higher extubation, and recovery times. When patients' temperature decreases by >1 or 1.5°, lower age and longer durations of operation and anesthesia were also significant variables. The incidence of shivering is quite high at temperatures below 36°C or at 1 and 1.5°C reductions from baseline (72.7%, 84%, 94.1%, respectively). Body temperature changes of the patients had no effect on nausea-vomiting and pain scores. It turned out that the incidence of PH and shivering is high in women who underwent breast surgery. We think that the depth of decrease in body temperature should be taken into account when evaluating the predictors or clinical consequences of hypothermia, except for the 36°C limit for body temperature.

Use of Artificial Intelligence in the Advancement of Breast Surgery and Implications for Breast Reconstruction: A Narrative Review

BACKGROUND

Breast reconstruction is a pivotal part of the recuperation process following a mastectomy and aims to restore both the physical aesthetic and emotional well-being of breast cancer survivors. In recent years, artificial intelligence (AI) has emerged as a revolutionary technology across numerous medical disciplines. This narrative review of the current literature and evidence analysis explores the role of AI in the domain of breast reconstruction, outlining its potential to refine surgical procedures, enhance outcomes, and streamline decision making.

METHODS

A systematic search on Medline (via PubMed), Cochrane Library, Web of Science, Google Scholar, Clinical Trials, and Embase databases from January 1901 to June 2023 was conducted.

RESULTS

By meticulously evaluating a selection of recent studies and engaging with inherent challenges and prospective trajectories, this review spotlights the promising role AI plays in advancing the techniques of breast reconstruction. However, issues concerning data quality, privacy, and ethical considerations pose hurdles to the seamless integration of AI in the medical field.

CONCLUSION

The future research agenda comprises dataset standardization, AI algorithm refinement, and the implementation of prospective clinical trials and fosters cross-disciplinary partnerships. The fusion of AI with other emergent technologies like augmented reality and 3D printing could further propel progress in breast surgery.

Advances in the Management of Early-Stage Triple-Negative Breast Cancer

Triple-negative breast cancer (TNBC) is a subtype of breast cancer with both inter- and intratumor heterogeneity, thought to result in a more aggressive course and worse outcomes. Neoadjuvant therapy (NAT) has become the preferred treatment modality of early-stage TNBC as it allows for the downstaging of tumors in the breast and axilla, monitoring early treatment response, and most importantly, provides important prognostic information that is essential to determining post-surgical therapies to improve outcomes. It focuses on combinations of systemic drugs to optimize pathologic complete response (pCR). Excellent response to NAT has allowed surgical de-escalation in ideal candidates. Further, treatment algorithms guide the systemic management of patients based on their pCR status following surgery. The expanding knowledge of molecular pathways, genomic sequencing, and the immunological profile of TNBC has led to the use of immune checkpoint inhibitors and targeted agents, including PARP inhibitors, further revolutionizing the therapeutic landscape of this clinical entity. However, subgroups most likely to benefit from these novel approaches in TNBC remain elusive and are being extensively studied. In this review, we describe current practices and promising therapeutic options on the horizon for TNBC, surgical advances, and future trends in molecular determinants of response to therapy in early-stage TNBC.

Neoadjuvant therapy for HER2-positive acantholytic squamous cell breast carcinoma: a case report

HER2-positive acantholytic squamous cell carcinoma (ASCC) of the breast is exceptionally rare, and its clinicopathologic features are poorly understood. The impact of neoadjuvant therapy on HER2-positive breast ASCC is unclear. Here we report on a 58-year-old woman who was diagnosed with HER2-positive ASCC of the right breast, who underwent neoadjuvant treatment with albumin-paclitaxel, carboplatin, and trastuzumab, and surgery. Neoadjuvant therapy was effective, with no recurrence or metastasis after 1.5 years of postoperative follow-up.

Benchmarking Excellence: Evaluating Advanced Breast Carcinoma Care in Pakistan's Largest Cancer Hospital Against the National Institute for Health and Care Excellence (NICE) Guidelines

Introduction Breast cancer is the most common type of cancer worldwide, and even with all the screening and education, great numbers of diagnoses are made in advanced stages. Additionally, patients in remission always remain at risk of relapse and metastasis. Pakistan has the highest incidence of breast cancer among Asian countries. The purpose of this clinical audit was to compare data from the largest cancer hospital in Pakistan with international standards to provide room for quality improvement. Methods A retrospective review of patients with advanced breast carcinoma over a period of six months was done. Permission was obtained from the Quality Assurance and Patent Safety Department before the commencement of the audit. Standards Data obtained were audited against nine standards of four different categories from the National Institute for Health and Care Excellence (NICE) guidelines on advanced breast carcinoma. Results For the diagnosis and assessment category, for which a target of 100% was set, 99.66% was achieved; for disease monitoring, for which a target of 100% was set, 91.8% was achieved; for systemic disease-modifying therapy, for which the majority was the target, only 1% was achieved; for managing complications, for which a target of 100% was set, 71.8% was achieved. Conclusion Continuous research and breakthrough advancements have made health care an ever-evolving field. Clinical audits like these that compare international standards with local data are beneficial and lead to quality improvement. They highlight issues that may be overlooked otherwise, raise questions that may never be asked, and may inspire prospective research studies. Limitations of the audit were that this clinical audit was conducted outside of the NHS where NICE guidelines are not followed and local guidelines differ from NICE guidelines.

[Update and Trends in Breast Reconstruction After Mastectomy]

Due to refinements in operating techniques, autologous breast reconstruction has become part of standard care. It has become more difficult to advise patients due to the expansion of oncologic options for mastectomy, radiation therapy and the variety of reconstructive techniques. The goal of reconstruction is to achieve oncologically clear margins and a long-term aesthetically satisfactory result with a high quality of life. Immediate reconstruction preserves the skin of the breast and its natural form and prevents the psychological trauma associated with mastectomy. However, secondary reconstructions often have a higher satisfaction, since here no restitutio ad integrum is assumed. Alloplastic, i. e., implant-based, breast reconstruction and autologous breast reconstruction are complementary techniques. This article provides an overview of current options for breast reconstruction including patients' satisfaction and quality of life following breast reconstruction. Although immediate reconstruction is still the preferred choice of most patients and surgeons, delayed reconstruction does not appear to compromise clinical or patient-reported outcomes. Recent refinements in surgical techniques and autologous breast reconstruction include stacked-flaps, as well as microsurgical nerve coaptation to restore sensitivity, which lead to improved outcomes and quality of life. Nowadays Skin-sparing and nipple-sparing mastectomy, accompanied by improved implant quality, allows immediate prosthetic breast reconstruction as well as reemergence of the prepectoral implantation. The choice of breast reconstruction depends on the type of mastectomy, necessary radiation, individual risk factors, as well as the patient's habitus and wishes. Overall, recent developments in breast reconstruction led to an increase in patient satisfaction, quality of life and aesthetic outcome with oncological safety.

New Robotic Platforms in General Surgery: What's the Current Clinical Scenario?

Background and Objectives: Robotic surgery has been widely adopted in general surgery worldwide but access to this technology is still limited to a few hospitals. With the recent introduction of new robotic platforms, several studies reported the feasibility of different surgical procedures. The aim of this systematic review is to highlight the current clinical practice with the new robotic platforms in general surgery. Materials and Methods: A grey literature search was performed on the Internet to identify the available robotic systems. A PRISMA compliant systematic review was conducted for all English articles up to 10 February 2023 searching the following databases: MEDLINE, EMBASE, and Cochrane Library. Clinical outcomes, training process, operating surgeon background, cost-analysis, and specific registries were evaluated. Results: A total of 103 studies were included for qualitative synthesis after the full-text screening. Of the fifteen robotic platforms identified, only seven were adopted in a clinical environment. Out of 4053 patients, 2819 were operated on with a new robotic device. Hepatopancreatobiliary surgery specialty performed the majority of procedures, and the most performed procedure was cholecystectomy. Globally, 109 emergency surgeries were reported. Concerning the training process, only 45 papers reported the background of the operating surgeon, and only 28 papers described the training process on the surgical platform. Only one cost-analysis compared a new robot to the existing reference. Two manufacturers promoted a specific registry to collect clinical outcomes. Conclusions: This systematic review highlights the feasibility of most surgical procedures in general surgery using the new robotic platforms. Adoption of these new devices in general surgery is constantly growing with the extension of regulatory approvals. Standardization of the training process and the assessment of skills' transferability is still lacking. Further studies are required to better understand the real clinical and economical benefit.

Interpreting the BREAST-Q for Breast-Conserving Therapy: Minimal Important Differences and Clinical Reference Values

BACKGROUND

The BREAST-Q is an important tool for evaluating patient satisfaction and quality of life in breast-conserving therapy (BCT) patients, but its clinical utility is limited by the lack of guidance on score interpretation. This study determines reference values and the minimal important difference (MID) for the BREAST-Q BCT module.

METHODS

A retrospective review of BCT patients at Memorial Sloan Kettering Cancer Center from January 2011 to December 2021 was performed. Descriptive statistics were used to summarize median BREAST-Q scores. Distribution-based analyses estimated MIDs based on 0.2 standard deviation of baseline BREAST-Q scores and 0.2 standardized response mean of the difference between baseline and 1-year postoperative BREAST-Q scores. MIDs for different clinical groupings based on body mass index, radiation, and reexcision also were estimated.

RESULTS

Overall, 8060 patients were included for determining reference values, and 5673 patients were included for estimating MIDs. Median BREAST-Q scores trended upwards and stabilized by 2 years after surgery for all domains except Physical Well-Being of the Chest, which decreased and stabilized by 2 years. A score interpretation tool, the Real-Time Engagement and Communication Tool, was created based on 25th percentile, median, and 75th percentile scores trajectories. All MID estimates ranged from 3 to 5 points; 4 points was determined to be appropriate for use in clinical practice and research.

CONCLUSIONS

Reference values and MIDs are crucial to BREAST-Q score interpretation, which can lead to improved clinical evaluation and decision making and improved research methodology. Future research should validate this study's findings in different patient cohorts.

The Efficacy of Antiseptic Treatment of Surgical Drains on Bacterial Colonisation and Surgical Site Infection Post Breast Surgery: A Systematic Review and Meta-Analysis

Surgical site infection (SSI) is a common complication in women with post-operative drains following breast surgery, with the risk being as high as 19%. The authors aimed to conduct the first meta-analysis to determine the efficacy of antiseptic treatment of drains to reduce the incidence of infections by comparing it to drains with no antiseptic coating. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed with an extensive search of the electronic databases retrieving 114 articles. Four articles met the inclusion criteria. The primary outcome measure was the incidence of SSIs and secondary outcome measures included the incidence of bacterial colonisation in the bulb fluid and drain tube. The incidence of SSIs was significantly lower in the antiseptic group compared to the control (CI 95% 0.09 - 0.82, p = 0.02). In addition, there was a lower incidence of colonisation from both the bulb fluid and drain tube with P values of < 0.00001 and P < 0.0001 respectively. The authors report the first meta-analysis within the literature showing the efficacy of antiseptic treatment of surgical drains on colonisation and SSIs following breast surgery. More high-quality trials are recommended to further the current evidence base.

Complete Decongestive Therapy Effect on Breast Cancer Related to Lymphedema: A Systemic Review and Meta-Analysis of Randomized Controlled Trials

PURPOSE

To review and analyze critically the available evidence for Complete Decongestive Therapy Effect on Breast Cancer Related to Lymphedema.

DATA SOURCES

Publications were retrieved from the major database search engines, included  Google scholar, EBSCO host, and PubMed database. The search terms including: "Complete decongestive therapy (CDT)", "breast cancer", "Breast cancer related to lymphedema (BCRL)" "breast surgery" and "mastectomy".

STUDY SELECTION

The studies were initially selected based on keywords associated with inclusion criteria. Then, articles were chosen based on their titles. Then, based on the fill text and design, randomized control with a comprehensive description of the outcomes. The authors analyzed 3,181 articles, of which 15 randomized controlled trials met inclusion criteria with no publication date constraint.

DATA EXTRACTION

Each article's authors, nations, participants, outcomes variables, measuring instruments, intervention technique and follow-up, outcomes, and results were retrieved. After reaching consensus among authors, study quality was evaluated using the Jadad scale, and risk of bias was determined using the Cochrane Rob2 tool.

DATA SYNTHESIS

The levels of evidence were of excellent quality. The retrieved articles were of "high" methodological caliber. The major outcome variables were in QOL, pain, ROM and edema. The effect size of CDT on QOL was 2.347 (95% CI: -1.41, 6.11) (p=0.22). Pain was -0.068 (95% CI: -35.21) (p=0.64). ROM was 0.324 (95% CI: -0.44,0.09) (p=0.41) and edema was -2.9 (95% -1.53,1.11) (p=0.76).

CONCLUSIONS

The CDT is still recommended as the primary therapy for BCRL and is regarded the most practical and cost-effective treatment for BCRL. This result recommends patients to perform CDT to improve their QOL, ROM, and to lessen pain and edema volume. To improve the body of evidence supporting the effectiveness of the CDT on BCRL, additional trials with bigger sample sizes, longer follow-ups, blindness outcomes, and patient compliance evaluations are required.

Optimizing Acellular Dermal Matrix Integration in Heterologous Breast Reconstructive Surgery: Surgical Tips and Post-Operative Management

Background and Objective: Prepectoral implant placement in breast reconstruction is currently a must-have in the portfolios of breast surgeons. The introduction of new tools and conservative mastectomies is a game changer in this field. The prepectoral plane usually goes hand-in-hand with the ADM wrapping of the implant. It is a cell-free dermal matrix comprising a structurally integrated basement membrane complex and an extracellular matrix. The literature reports that ADMs may be useful, but proper patient selection, surgical placement, and post-operative management are essential to unlock the potential of this tool, as these factors contribute to the proper integration of the matrix with surrounding tissues. Materials and Methods: A total of 245 prepectoral breast reconstructions with prostheses or expanders and ADMs were performed in our institution between 2016 and 2022. A retrospective study was carried out to record patient characteristics, risk factors, surgical procedures, reconstructive processes, and complications. Based on our experience, we developed a meticulous reconstruction protocol in order to optimize surgical practice and lower complication rates. The DTI and two-stage reconstruction were compared. Results: Seroma formation was the most frequent early complication (less than 90 days after surgery) that we observed; however, the majority were drained in outpatient settings and healed rapidly. Secondary healing of wounds, which required a few more weeks of dressing, represented the second most frequent early complication (10.61%). Rippling was the most common late complication, particularly in DTI patients. After comparing the DTI and two-stage reconstruction, no statistically significant increase in complications was found. Conclusions: The weakness of prepectoral breast reconstruction is poor matrix integration, which leads to seroma and other complications. ADM acts like a graft; it requires firm and healthy tissues to set in. In order to do so, there are three key steps to follow: (1) adequate patient selection; (2) preservative and gentle handling of intra-operative technique; and (3) meticulous post-operative management.

Limberg flap in mastectomy T-junction necrosis: an underutilised technique

The Wise-pattern skin-sparing mastectomy (SSM) is well known for its efficacy in large ptotic breasts, and its safety in facilitating immediate breast reconstruction. An unfortunate sequalae for all SSM techniques is mastectomy skin flap necrosis (MSFN) with a reported range of occurrence of 5%-30%. For the Wise pattern, the common area of wound dehiscence or necrosis is the T-junction. Different techniques have been described in the management of MSFN-ranging from primary closure to local and distant flaps. Full thickness MSFN results in wound breakdown and can expose a prosthesis, subsequently closure must be obtained with potential for the prosthesis to be explanted. To date, there has been no reports in the literature of the usage of a rhomboid flap in an SSM with immediate prepectoral implant. We discuss our experience in the usage of this local cosmetic flap to avoid prosthesis loss and have reviewed the literature regarding MSFN, the application of the rhomboid (Limberg) flap in breast surgery and its applicability in MSFN to preserve underlying prosthesis.

Perioperative intravenous lidocaine for postoperative pain in patients undergoing breast surgery: a meta-analysis with trial sequential analysis of randomized controlled trials

Background

The effectiveness of intravenous lidocaine infusion in managing acute and chronic pain following breast surgery has been a topic of debate. This meta-analysis aims to assess the impact of perioperative intravenous lidocaine on the relief of postoperative pain among patients undergoing breast surgery.

Methods

A systematic search of databases was conducted to identify randomized controlled trials (RCTs) that compared the effects of intravenous lidocaine infusion with placebo or routine care in patients undergoing breast surgery. The primary outcome of interest was the occurrence of chronic post-surgical pain (CPSP) at the longest follow-up. Meta-analyses, incorporating trial sequential analysis, were performed using a random-effects model to assess the overall effect.

Results

A total of twelve trials, involving 879 patients, were included in the analysis. Perioperative intravenous lidocaine demonstrated a significant reduction in the incidence of CPSP at the longest follow-up (risk ratio [RR] 0.62, 95% confidence interval [CI] 0.48-0.81; P = 0.0005; I2 = 6%). Trial sequential analysis (TSA) indicated that the cumulative z curve crossed the trial sequential monitoring boundary for benefit, providing sufficient and conclusive evidence. Furthermore, intravenous lidocaine was associated with decreased opioid consumption and a shorter length of hospital stay.

Conclusion

Perioperative intravenous lidocaine is effective in relieving acute and CPSP in patients undergoing breast surgery.

Study on effectiveness analysis of multi-media combined with PBL teaching in breast surgery

Objective

To explore the effectiveness of multi-media combined with PBL teaching in breast surgery.

Methods

56 interns who came to our hospital for breast surgery from January 2019 to December 2020 were randomly divided into two groups: traditional teaching control group (n = 28) and multi-media PBL teaching observation group (n = 28). Two groups' theoretical knowledge, skill operation, teaching quality, student's evaluation and satisfaction with the teaching model were compared before ending the internship.

Results

The total scores of breast examination, differential diagnosis, imaging reading, diagnosis and treatment scheme and total scores of the students in the observation group were higher than those of the students in the control group, and the total scores of body position, surgical site selection, disinfection and local anesthesia, surgical operation, postoperative treatment and clinical operation skills were also higher than those of the students in the control group (P < 0.05), but there was no significant difference between the two groups in medical history collection, professional knowledge and preoperative preparation (P > 0.05). The teaching quality of the students in the observation group was also significantly higher than that in the control group (P < 0.05). In addition, the students' satisfaction with the teaching method, the teaching effect and the overall satisfaction in the observation group were significantly higher than those in the control group (P < 0.05).

Conclusion

Multi-media combined with PBL teaching can effectively improve students' professional knowledge theory level, operation skills, enhance students' enthusiasm and initiative, develop good clinical thinking habits, and have high teaching satisfaction. It is worthy of being popularized in the clinical teaching of breast surgery.

Nagor Impleo Round Silicone Gel Breast Implants: Early Outcome Analysis after 340 Primary Breast Augmentations

For decades, implant-based breast augmentation has been one of the most performed surgical procedures for cosmetic purposes around the world. Hence, novel manufactured implants should be critically investigated to prove them safe and effective. Here, the authors describe the first independently conducted clinical study on Nagor Impleo textured round breast implants. For this retrospective study, outcomes of 340 consecutive female patients undergoing primary cosmetic breast augmentation were analyzed. Demographic and surgical data as well as outcomes and complications were evaluated. Furthermore, a survey concerning effectiveness and aesthetic satisfaction after breast augmentation was examined. All 680 implants were placed in a submuscular plane with incisions at the inframammary fold. The main indications for surgery were hypoplasia and hypoplasia with asymmetry. The mean implant volume was 390 cc and the main type of projection was high profile. The most common complications were hematoma and capsular contracture (0.9 percent, respectively). The overall revision rate for complications was 2.4%. Additionally, almost all patients showed increased quality of life and aesthetic satisfaction after a breast augmentation. Hence, all patients would undergo breast augmentation again with these newly launched devices. Nagor Impleo implants demonstrate a low complication rate and high safety profile. Although high aesthetic satisfaction and quality of life results were achieved, analysis of an even larger series over a longer period of time would be beneficial to evaluate the reliability of this implant.

Outcomes of a Multidisciplinary Team in the Management of Patients with Early-Stage Breast Cancer Undergoing Neoadjuvant Chemotherapy at a Community Cancer Center

Background: The utilization of neoadjuvant chemotherapy (NAC) remains highly variable in clinical practice. The implementation of NAC requires coordination of handoffs between a multidisciplinary team (MDT). This study aims to assess the outcomes of an MDT in the management of early-stage breast cancer patients undergoing neoadjuvant chemotherapy at a community cancer center. Methods: We conducted a retrospective case series on patients receiving NAC for early-stage operable or locally advanced breast cancer coordinated by an MDT. Outcomes of interest included the rate of downstaging of cancer in the breast and axilla, time from biopsy to NAC, time from completion of NAC to surgery, and time from surgery to radiation therapy (RT). Results: Ninety-four patients underwent NAC; 84% were White and mean age was 56.5 yrs. Of them, 87 (92.5%) had clinical stage II or III cancer, and 43 (45.8%) had positive lymph nodes. Thirty-nine patients (42.9%) were triple negative, 28 (30.8%) were human epidermal growth factor receptor (HER-2)+, and 24 (26.2%) were estrogen receptor (ER) +HER-2-. Of 91 patients, 23 (25.3%) achieved pCR; 84 patients (91.4%) had downstaging of the breast tumor, and 30 (33%) had axillary downstaging. The median time from diagnosis to NAC was 37.5 days, the time from completion of NAC to surgery was 29 days, and the time from surgery to RT was 49.5 days. Conclusions: Our MDT provided timely, coordinated, and consistent care for patients with early-stage breast cancer undergoing NAC as evidenced by time to treatment outcomes consistent with recommended national trends.
