BACKGROUND
Nipple adenomas (NAs) are rare benign proliferative tumors presenting as palpable nodules, erosive lesions, or nipple discharge, mimicking other conditions. This systematic review categorizes cases into sole NA (ONA) or co-diagnoses with other conditions (CONA) to enhance clinical recognition, diagnosis, and treatment efficacy.
METHODS
Following PRISMA guidelines, a PubMed search was conducted for NA. Inclusion criteria covered original research, excluding reviews or other breast diseases. Bias risk was assessed through a thorough search, authors independently evaluated studies, and data were synthesized using varied measures. Subgroups ONA and CONA were formed. Analyses were conducted in Excel and R, complemented by a qualitative review due to case report predominance. Biases in case reports were transparently addressed.
RESULTS
Of the 86 studies, 387 cases were analyzed, showing 10.34% with co-diagnoses of malignant or premalignant conditions. Mean age was 44, with a female predominance (97%). ONA (347 cases) and CONA (40 cases) subgroups exhibited variations in symptoms, physical findings, and imaging. Treatment modalities included excision (51.39%), biopsy alone (11.1%), and mastectomy (8.6%). Mean follow-up of 56.73 months revealed recurrence (2.87%) and malignancy development (1.79%), notably in CONA cases (33.33%).
CONCLUSIONS
This study provides insights into the broader age range of NA and its associations. Higher co-diagnosis rates were correlated with older age, highlighting the necessity for thorough investigation, with excision as the primary treatment. Follow-up emphasizes the significance of identifying and monitoring CONA cases, which pose a higher malignancy risk. Recurrence is presumed to be linked to proper lesion excision and co-diagnosis.

BACKGROUND
Breast reconstruction is a standard procedure in postmastectomy plastic surgery. The necessity of routine histological examinations for mastectomy scars during delayed reconstruction remains a topic of debate. We evaluated the need for histological examination of scars during delayed breast reconstruction.
METHODS
We conducted a systematic review using PubMed, TDnet, and Cochrane Central in August 2023. Inclusion criteria involved delayed breast reconstruction with histological scar analysis and malignancy reporting. Exclusion criteria encompassed noncancerous breast diseases, prophylactic mastectomies, articles lacking relevant information, case reports, technique descriptions, and reviews. We independently assessed articles. Differences in recurrence rates were determined using a Z-test for proportions. A linear regression model explored the relationship between reconstruction timing and pathological results. The number needed to treat was calculated based on the literature. The Wilcoxon test was used to compare mean reconstruction times and postreconstruction follow-up between groups.
RESULTS
Our analysis covered 11 retrospective observational studies published between 2003 and 2018, including 3754 mastectomy scars. The malignancy recurrence rate was 0.19%, consistent with previous reports, with a number needed to treat of 144.93-188.68 patients. The timing of breast reconstruction postmastectomy averaged 19.9 months, without statistically significant association between reconstruction timing and recurrence rates. Postreconstruction follow-up periods ranged from 60 to 87 months. The postreconstruction adverse outcomes ratio was 2.21%.
CONCLUSIONS
Assessing the necessity of histological examination in breast reconstruction is complex. Based on the literature and this study, we do not recommend routine histological examination of mastectomy scars during delayed reconstruction. A selective approach based on risk factors may be beneficial, warranting further research.

Meta-Analysis
INTRODUCTION
Venous thromboembolism (VTE) events are a preventable complication for patients undergoing surgery for breast cancer. However, there is a lack of consistency in the existing literature regarding the potential risk factors affecting these individuals.
METHODS
This study aimed to investigate the potential risk factors associated with an increased risk of VTE following surgery for breast cancer. Data on patient characteristics such as age, body mass index (BMI), existing comorbidities, smoking history, surgical interventions, duration of hospitalization, and post-operative complications were recorded and analyzed.
RESULTS
Thirty-one studies investigating the incidence of VTE following surgical interventions for breast cancer were included. This study included 22,155 female patients with a mean age of 50.8 ± 2.9 years. The weighted mean length of surgery and hospital stay were 382.1 ± 170.0 min and 4.5 ± 2.7 days, respectively. The patients were followed-up for a weighted mean duration of 13.8 ± 21.2 months. The total incidence of VTE events was 2.2% (n = 489). Meta-analysis showed that patients with post-operative VTE had a significantly higher mean age and BMI, as well as longer mean length of surgery (P < 0.05). Comparing the techniques of autologous breast reconstruction showed that the risk of post-operative VTE is significantly higher with deep inferior epigastric perforator (DIEP) flaps, compared with the transverse rectus abdominus myocutaneous and latissimus dorsi myocutaneous flaps (P < 0.05). Compared with delayed reconstruction, immediate reconstruction was associated with a significantly higher incidence of VTE (P < 0.05). Smoking history, length of hospital stay, and Caprini score did not correlate with increased incidence of post-operative VTE.
CONCLUSION
The incidence rate of VTE events in patients receiving surgical treatment for breast cancer is 2.2%. Risk factors for developing post-operative VTE in this patient population were found to be older age, increased BMI, extended length of surgical procedures, and DIEP flap reconstruction.

Review
BACKGROUND
Exclusive fat grafting is an alternative method to implant- or flap- based reconstruction techniques following mastectomies or breast conservation therapies. Its efficacy has been explored before but new data has come to light, resulting in previous results becoming outdated. Concerns have also been raised about the oncological safety of this procedure which must be evaluated alongside the efficacy to gain a comprehensive understanding of the merits of this alternative technique.
METHODS
We queried the PubMed electronic database from its inception until August 2023 for studies evaluating the efficacy and oncological safety of exclusive fat grafting breast reconstruction following cancer-related mastectomy or breast conservation therapy. Results of the analysis were pooled and presented as means or valid proportions. Results of the analysis were pooled using a random-effects model and presented with 95% confidence intervals (95% CIs) where appropriate.
RESULTS
41 studies were included in our analysis. Pooled results show that on average, 1.7 sessions of exclusive fat grafting were required to complete reconstruction in Breast Conservation Therapy (BCT) patients, with an average volume of 114.2 ml being injected. For mastectomy patients with irradiated breasts, 4.7 sessions were needed on average with 556.8 ml being required to complete reconstruction, compared to their non-irradiated Counterparts requiring only 2.6 sessions and 207.2 ml to complete reconstruction. Oncological recurrence events were found in 29/583 non-irradiated mastectomy patients (p = 0.014) and in 41/517 BCT patients (p = 0.301) CONCLUSION: Exclusive fat grafting is an oncologically safe and reasonably efficacious alternative to more common methods of breast reconstruction. More data is needed to fully characterize the oncological safety of this procedure in irradiated and non-irradiated mastectomy patients.

Meta-Analysis
BACKGROUND
Breast-conserving surgery with adjuvant radiotherapy and mastectomy are currently offered as equivalent surgical options for early-stage breast cancer based on RCTs from the 1970s and 1980s. However, the treatment of breast cancer has evolved and recent observational studies suggest a survival advantage for breast-conserving surgery with adjuvant radiotherapy. A systematic review and meta-analysis was undertaken to summarize the contemporary evidence regarding survival after breast-conserving surgery with adjuvant radiotherapy versus mastectomy for women with early-stage breast cancer.
METHODS
A systematic search of MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL), and Embase that identified studies published between 1 January 2000 and 18 December 2023 comparing overall survival after breast-conserving surgery with adjuvant radiotherapy versus mastectomy for patients with unilateral stage 1-3 breast cancer was undertaken. The main exclusion criteria were studies evaluating neoadjuvant chemotherapy, rare breast cancer subtypes, and specific breast cancer populations. The ROBINS-I tool was used to assess risk of bias, with the overall certainty of evidence assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool. Studies without critical risk of bias were included in a quantitative meta-analysis.
RESULTS
From 11 750 abstracts, 108 eligible articles were identified, with one article including two studies; 29 studies were excluded from the meta-analysis due to an overall critical risk of bias, 42 studies were excluded due to overlapping study populations, and three studies were excluded due to reporting incompatible results. A total of 35 observational studies reported survival outcomes for 909 077 patients (362 390 patients undergoing mastectomy and 546 687 patients undergoing breast-conserving surgery with adjuvant radiotherapy). The pooled HR was 0.72 (95% c.i. 0.68 to 0.75, P < 0.001), demonstrating improved overall survival for patients undergoing breast-conserving surgery with adjuvant radiotherapy. The overall certainty of the evidence was very low.
CONCLUSION
This meta-analysis provides evidence suggesting a survival advantage for women undergoing breast-conserving surgery with adjuvant radiotherapy for early-stage breast cancer compared with mastectomy. Although these results should be interpreted with caution, they should be shared with patients to support informed surgical decision-making.

BACKGROUND
Implant-based breast reconstruction after nipple-sparing mastectomy (NSM) presents unique benefits and challenges. The literature has compared outcomes among total submuscular (TSM), dual-plane (DP), and prepectoral (PP) planes; however, a dedicated meta-analysis relevant to NSM is lacking.
METHODS
We conducted a systematic review of studies on immediate breast reconstruction after NSM using TSM, DP, or PP prosthesis placement in PubMed, Embase, and Cochrane databases. In total, 1317 unique articles were identified, of which 49 were included in the systematic review and six met inclusion criteria for meta-analysis. Pooled descriptive outcomes were analyzed for each cohort for all 49 studies. Fixed-effects meta-analytic methods were used to compare PP with subpectoral (TSM and DP) reconstructions.
RESULTS
A total of 1432 TSM, 1546 DP, and 1668 PP reconstructions were identified for descriptive analysis. Demographics were similar between cohorts. Pooled descriptive outcomes demonstrated overall similar rates of reconstructive failure (3.3%-5.1%) as well as capsular contracture (0%-3.9%) among cohorts. Fixed-effects meta-analysis of six comparative studies demonstrated a significantly lower rate of mastectomy flap necrosis in the PP cohort compared with the subpectoral cohort (relative risk 0.24, 95% confidence interval [0.08-0.74]). All other consistently reported outcomes, including, hematoma, seroma, infection, mastectomy flap necrosis, nipple -areola complex necrosis, and explantation were comparable.
CONCLUSIONS
A systematic review of the literature and meta-analysis demonstrated the safety of immediate prepectoral breast reconstruction after NSM, compared with submuscular techniques. Submuscular reconstruction had a higher risk of mastectomy flap necrosis, though potentially influenced by selection bias.

Review
INTRODUCTION
Transition-related surgery is an effective treatment for gender dysphoria, but the perioperative analgesic management of transgender patients is nuanced and potentially complicated by higher rates of mood and substance use disorders. Regional anesthetic techniques are known to reduce pain severity and opioid requirements; however, little is known regarding the relative analgesic effectiveness of regional anesthesia for transgender patients undergoing transition-related surgery.
METHODS
We performed a systematic review of the literature to evaluate original reports characterizing the analgesic effectiveness of regional anesthetic techniques for patients undergoing chest and/or genital transition-related surgery. Our primary outcomes were pain severity and opioid requirements on the first postoperative day.
RESULTS
Of the 1863 records identified, 10 met criteria for inclusion and narrative synthesis. These included two randomized controlled trials, three cohort studies, and five case reports/series, comprising 293 patients. Four reports described 243 patients undergoing chest surgery, of whom 86% were transgender men undergoing mastectomy with pectoralis nerve blocks or local anesthetic instillation devices. The remaining six reports comprised 50 patients undergoing genital surgery, of whom 56% were transgender women undergoing vaginoplasty with erector spinae plane blocks or epidural anesthesia. Three studies directly compared regional techniques to parenteral analgesia alone. Two of these studies reported lower pain scores and opioid requirements on the first postoperative day with nerve blocks compared with none while the third study reported no difference between groups. Complications related to regional anesthetic techniques were rare among patients undergoing transition-related surgery.
DISCUSSION
Despite the ever-growing demand for transition-related surgery, the relative analgesic effectiveness of regional anesthesia for transgender patients undergoing transition-related surgery is very understudied and insufficient to guide clinical practice. Our systematic review of the literature serves to underscore regional anesthesia for transition-related surgery as a priority area for future research.

Review
BACKGROUND
Outcomes of immediate breast reconstructions can be influenced by postoperative radiotherapy. However, there is no clarity on the use of prepectoral or subpectoral breast reconstruction in the setting of postmastectomy radiation therapy (PMRT). We reviewed evidence on the complication rates of prepectoral and subpectoral breast reconstruction in women undergoing PMRT.
METHODS
PubMed, Web of Science, and Embase databases were scanned for studies comparing complication rates of prepectoral and subpectoral breast reconstruction with PMRT. All complications were pooled in a random-effect meta-analysis to obtain odds ratio (OR).
RESULTS
Eight observational studies were included. Meta-analysis showed no difference in the risk of infections (OR: 1.22 95% CI 0.79, 1.88 I=0%), implant loss (OR: 0.86 95% CI 0.50, 1.50 I=14%), seroma (OR: 1.01 95% CI 0.43, 2.34 I=50%), hematoma (OR: 0.44 95% CI 0.12, 1.71 I=0%), wound dehiscence (OR: 0.95 95% CI 0.42, 2.17 I=0%), and skin necrosis (OR: 0.61 95% CI 0.21, 1.75 I=36%), contracture (OR: 0.46 95% CI 0.15, 1.48 I=54%) and the need for revision surgeries (OR: 0.85 95% CI 0.45, 1.60 I=15%) between the prepectoral and subpectoral groups.
CONCLUSIONS
Data from observational studies indicates that in appropriately selected patients there may not be any difference in the risk of early complications with prepectoral or subpectoral breast reconstruction with PMRT. Current evidence is limited by the small number of studies, short follow-up and selection bias. There is a need for randomized controlled trials comparing the two approaches to obtain robust evidence on long-term outcomes.

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.

Review
Nowadays, multimodal cancer therapy results in very high survival rates of early-stage breast cancer and microsurgical flap-based breast reconstruction has become safe and reliable, with gradually increasing demand because of its durable and aesthetically pleasing results. This study aimed to explore the impact of different flap shaping and inset techniques on patient-reported outcome measures (PROMs) with regard to the aesthetic result in abdominal flap-based breast reconstruction. A systematic review was performed screening Pubmed, Cochrane Library and Web of Science for original articles reporting flap inset strategies, concomitantly providing PROMs on the aesthetic result. Of 319 studies identified, six met the inclusion criteria. The studies described different flap rotation options according to the patient's morphology, different inset planes, and avoidance of the monitoring skin paddle, and suggested that a higher flap-to-mastectomy mass ratio was associated with better aesthetic results. In two comparative studies, according to the PROMs (BREAST-Q, Likert scale) and independent observer judgement, both higher patient satisfaction and superior aesthetic results were observed with the newly described techniques. Emphasis on the aesthetic outcome in terms of breast shape and symmetry, providing an individualized approach of flap inset, considering the contralateral breast's shape and volume, results in higher satisfaction scores.
