Meta-Analysis
BACKGROUND
Early-stage breast cancer is among the most common cancer diagnoses. Adjuvant radiotherapy is an essential component of breast-conserving therapy, and several options exist for tailoring its extent and duration. This study assesses the comparative effectiveness of partial-breast irradiation (PBI) compared with whole-breast irradiation (WBI).
METHODS
A systematic review was completed to identify relevant randomized clinical trials and comparative observational studies. Independent reviewers working in pairs selected studies and extracted data. Randomized trial results were pooled using a random effects model. Prespecified main outcomes were ipsilateral breast recurrence (IBR), cosmesis, and adverse events (AEs).
RESULTS
Fourteen randomized clinical trials and 6 comparative observational studies with 17 234 patients evaluated the comparative effectiveness of PBI. PBI was not statistically significantly different from WBI for IBR at 5 years (RR = 1.34, 95% CI = 0.83 to 2.18; high strength of evidence [SOE]) and 10 years (RR = 1.29, 95% CI = 0.87 to 1.91; high SOE). Evidence for cosmetic outcomes was insufficient. Statistically significantly fewer acute AEs were reported with PBI compared with WBI, with no statistically significant difference in late AEs. Data from subgroups according to patient, tumor, and treatment characteristics were insufficient. Intraoperative radiotherapy was associated with higher IBR at 5, 10, and over than 10 years (high SOE) compared with WBI.
CONCLUSIONS
Ipsilateral breast recurrence was not statistically significantly different between PBI and WBI. Acute AEs were less frequent with PBI. This evidence supports the effectiveness of PBI among selected patients with early-stage, favorable-risk breast cancer who are similar to those represented in the included studies.

Meta-Analysis Review
STUDY OBJECTIVE
Due to conflicting results published in the literature regarding the analgesic superiority between the paravertebral block and the PECS block, the study objective is to determine which one should be the first line analgesic treatment after radical mastectomy.
DESIGN
Systematic review, meta-analysis and trial sequential analysis.
SETTING
Operating room, postoperative recovery area and ward, up to 24 postoperative hours.
PATIENTS
Patients scheduled for radical mastectomy under general anaesthesia.
INTERVENTIONS
We searched five electronic databases for randomized controlled trials comparing any PECS block with a paravertebral block.
MEASUREMENTS
The primary outcome was rest pain score (0-10) at 2 postoperative hours, analyzed according to the combination with axillary dissection or not, to account for heterogeneity. Secondary outcomes included rest pain scores, cumulative intravenous morphine equivalents consumption and rate of postoperative nausea and vomiting at 24 postoperative hours.
MAIN RESULTS
Eight trials including 388 patients were identified. Rest pain scores at 2 postoperative hours were decreased in the PECS block group, with a mean difference (95%CI) of -0.4 (-0.7 to -0.1), I = 68%, p = 0.01, and a significant subgroup difference observed between radical mastectomy with (mean difference [95%CI]: 0.0 [-0.2 to 0.2], I = 0%, p = 1.00), or without axillary dissection (mean difference [95%CI]: -0.7 [-1.1 to -0.4], I = 40%, p < 0.001; p for subgroup difference < 0.001). All secondary pain-related outcomes were similar between groups. The overall quality of evidence was low.
CONCLUSIONS
There is low quality evidence that a PECS block provides marginal postoperative analgesic benefit after radical mastectomy at 2 postoperative hours only, when compared with a paravertebral block, and not beyond. Clinical trial number: PROSPERO - registration number: CRD42019131555.

Review
INTRODUCTION
Less than 1% of all breast cancers are diagnosed in males. In females, postmastectomy breast reconstruction is associated with increased patient satisfaction. However, there is a paucity of literature describing reconstructive options for postmastectomy deformity in the male chest. The purpose of this systematic review was to evaluate postmastectomy reconstruction outcomes in males with breast cancer.
METHODS
A systematic review was performed in accordance with PRISMA guidelines. Ovid MEDLINE, Embase, Cochrane, and Web of Science were queried for records pertaining to the study question using medical subject heading (MeSH) terms such as "male breast cancer," "mastectomy," and "reconstruction." No limitations were placed on the year of publication, country of origin, or study size. Study characteristics and patient demographics were collected. Primary outcomes of interest included postoperative complications, recurrence rate, and mortality rate.
RESULTS
A total of 11 articles examining 29 male patients with breast cancer who underwent postmastectomy reconstruction were included for analysis. Literature was most commonly available in the form of case reports. The average age was 59.6 +/-11.4 years. Reconstruction methods included fat grafting ( = 1, 3.4%), silicone implants ( = 1, 3.4%), and autologous chest wall reconstruction with local flaps ( = 26, 89.7%). Postoperative complications occurred in two patients (6.8%), including partial nipple necrosis ( = 1) and hypertrophic scarring ( = 1). Of the studies reporting patient satisfaction, all patients were pleased with the aesthetic appearance of their chest.
CONCLUSION
This systematic review revealed the limited availability of research regarding postmastectomy chest reconstruction in males with breast cancer. Nevertheless, the evidence available suggests that reconstruction can restore a patient's body image and, thus, should be regularly considered and discussed with male patients. Larger studies are warranted to further shed light on this population.

Journal of Gynecology Obstetrics and... Dec 2022We performed a systematic review in order to describe the clinical presentation, therapeutic management and outcomes of malignant myoepitelioma of the breast.
OBJECTIVES
We performed a systematic review in order to describe the clinical presentation, therapeutic management and outcomes of malignant myoepitelioma of the breast.
SEARCH STRATEGY
A systematic search of MEDLINE and EMBASE references from January 1980 to Marsh 2020 was performed. We included articles that reported cases of malignant breast myoepithelioma. Data from eligible studies were independently extracted onto standardized forms by two reviewers.
RESULTS
31 articles including 47 cases of malignant breast myoepithelioma and 3 other unpublished cases managed in our establishment were included in this systematic review. The average age at diagnosis was 60.7 years old [range 30-81]. The average size of the tumor was 46mm [range 10 -230]. 30 patients had a partial mastectomy and 18 a total mastectomy. Only 15% of patient (7/48) had an axillary sentinel lymph node biopsy of whom one was positive. 33% of patients (16/48) had an axillary lymph node dissection which was positive for one patient. 19% (n=9) had adjuvant radiotherapy and 15% (n=7) had adjuvant chemotherapy. 33% (n=10) of patients with partial mastectomy had at least one recurrence, versus 5.5% (n=1) after a total mastectomy. The average time between the diagnosis and the first recurrence was 25.4 months [range: 1-50]. 64% (n=7) had a second partial mastectomy and only 18% (n=2) had a total mastectomy. 27% of patient had chemotherapy after their first recurrence and 27% had radiotherapy if it was not received in first line treatment. 40% (n=4/10) of patients with partial mastectomy who recurred have had at least 2 breast recurrences. 28% (n=14) of all patients had distant metastases. 20% of patients (n=10) died whose 80% (n=8) had distant metastatic disease.
CONCLUSIONS
This systematic review provided a precise summary of the clinical characteristics and treatment of patients presenting with Malignant breast myoepithelioma in the past 40 years. We anticipate that these results will help inform current investigations and treatment.

BACKGROUND
Surgical learning curves reflect the trainee's rate of progress in gaining skills and competence for new procedures. Complex interventions such as free tissue transfers, with various linked skills and competences, transferred to one procedure are likely to have steep learning curves. This work aimed to report influence of learning curves on outcomes such as success rate, operative time, and complication rates in plastic surgery procedures.
METHODS
The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A systematic database literature search (PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trails) was performed. Articles were included when reporting effects of learning curves on outcomes in plastic surgery procedures.
RESULTS
Twenty-nine articles focusing on learning curves in plastic surgery procedures were included. Studies reported on non-free flap breast reconstruction, mastectomy, and free flap reconstruction in general and for breast reconstruction and did not allow for pooling of the data because of heterogeneity. Most common outcomes for measuring improvements were success rate, operation time, and complication rate, which demonstrated improvements in almost all studies. Plateaus were reached in 45 to 100 cases for breast reconstructions and were not reported for other procedures. Only 2 studies did not find associations between surgical experience and clinical outcomes.
CONCLUSIONS
There are sparse data on learning curves in plastic surgery. Existing studies draw a heterogeneous picture, but especially free flap breast reconstructions seem to undergo learning curves with improvements in operative time, complication rates, and success rates. However, well-designed studies with clearly defined outcomes and comparison between surgeons of different levels over time should be performed.Systematic review registration: PROSPERO: CRD42018108634.

Review
UNLABELLED
Oncoplastic surgery consists a new approach for extending breast conserving surgery possibilities This manuscript aimed to systematically review data on the oncological outcome of oncoplastic breast surgery. Electronic databases were searched with the appropriate search term up to and included April 2013.
INCLUSION CRITERIA
full publications including at least 10 patients and providing evidence on at least one of the following outcomes: margin involvement, local recurrence, metastatic disease, death number. Forty studies including 2830 patients, met inclusion criteria; twenty one studies investigated volume displacement techniques; fifteen studies investigated volume replacement techniques; four studies presented data on various oncoplastic techniques. Study quality was low. The majority of studies were observational studies. The length of follow up was relatively short, with only two studies reporting a median duration longer than 60 months. Only seven studies including more than 100 patients. There was great variation in the frequency of margin involvement ranging between 0% and 36% of patients. Local recurrence was observed in 0-10.8% of patients. Distant metastasis was observed in 0-18.9% of patients. In conclusion, long term oncological outcome of oncoplastic surgery for breast cancer is not adequately investigated. Further research efforts should focus on Level I evidence on oncological outcome of oncoplastic surgery.

Meta-Analysis Review
BACKGROUND
Indocyanine green angiography (ICG-A) has been widely applied for intraoperative flap assessment in DIEP flap breast reconstruction. However, the beneficial effect of ICG-A in DIEP flap breast reconstruction is still uncertain and no standardized protocol is available. This study aims to analyze the clinical outcome and comprehensively review protocols of this field.
METHODS
A systematic review was conducted in MEDLINE, EMBASE, and Cochrane CENTRAL databases until September 15, 2022. Studies on the utility of intraoperative ICG-A in DIEP breast reconstruction were included. Data reporting reconstruction outcomes were extracted for pooled analysis.
RESULTS
A total of 22 studies were enrolled in the review, among five studies with 1021 patients included in the meta-analysis. The protocols of ICG-A assessment of DIEP flap varied among studies. According to the pooled results, the incidence of postoperative fat necrosis was 10.89% (50 of 459 patients) with ICG-A and 21.53% (121 of 562 patients) with clinical judgment. The risk for postoperative fat necrosis was significantly lower in patients with intraoperative ICG-A than without (RR 0.47 95% CI 0.29-0.78, p = .004, I = 51%). Reoperation occurred in 5 of 48 patients (10.42%) in the ICG-A group and in 21 of 64 patients (32.82%) in the control group summarized from reports in two studies. The risk for reoperation was lower in the ICG-A group than in the control group (RR 0.41 95% CI 0.18-0.93, p = .03, I = 0%). Other complications, including flap loss, seroma, hematoma, dehiscence, mastectomy skin necrosis, and infection, were comparable between the two groups. Heterogeneities among studies were acceptable. No significant influence of specific studies was identified in sensitivity analysis.
CONCLUSIONS
ICG-A is an accurate and reliable way to identify problematic perfusion of DIEP flaps during breast reconstruction. Protocols of ICG-A differed in current studies. Intraoperative ICG-A significantly decreases the rate of fat necrosis and reoperation in patients undergoing DIEP breast reconstruction. The synthesized results should be interpreted sensibly due to the sample size limitation. RCTs on the outcomes and high-quality studies for an optimized ICG-A protocol are still needed in the future.

Review
INTRODUCTION
Breast cancer affects at least 1 in 10 women in the UK, but most present with primary operable disease, which has an 80% 5-year survival rate overall.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of interventions after breast-conserving surgery for ductal carcinoma in situ? What are the effects of treatments for primary operable breast cancer? What are the effects of interventions in locally advanced breast cancer (stage IIIB)? We searched: Medline, Embase, The Cochrane Library and other important databases up to February 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 79 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: adding chemotherapy (cyclophosphamide/methotrexate/ fluorouracil and/or anthracycline and/or taxane-based regimens), or hormonal treatment to radiotherapy; adjuvant treatments (aromatase inhibitors, adjuvant anthracycline regimens, tamoxifen); axillary clearance; axillary dissection plus sentinel node dissection; axillary radiotherapy; axillary sampling; combined chemotherapy plus tamoxifen; chemotherapy plus monoclonal antibody (trastuzumab); extensive surgery; high-dose chemotherapy; hormonal treatment; less extensive mastectomy; less than whole breast radiotherapy plus breast conserving surgery; multimodal treatment; ovarian ablation; primary chemotherapy; prolonged adjuvant combination chemotherapy; radiotherapy (after breast-conserving surgery, after mastectomy, plus tamoxifen after breast-conserving surgery, to the internal mammary chain, and to the ipsilateral supraclavicular fossa, and total nodal radiotherapy); sentinel node biopsy; and standard chemotherapy regimens.

Meta-Analysis Review
BACKGROUND
This systematic review and meta-analysis aimed to synthesize the evidence on the preoperative characteristics, operative outcomes, and postoperative complications of simple and complex segmentectomy for lung cancer.
METHODS
A systematic review of EMBASE (through Ovid), MEDLINE (via PubMed), and Cochrane CENTRAL (January 1990 - January 2023) was done. We included studies to compare simple versus complex segmentectomies for lung cancer in terms of characteristics and operative and postoperative outcomes.
RESULTS
There was a statistically significant difference regarding higher operative time in favor of simple segmentectomies (Mean Difference, MD = 15.76, 95% Confidence Interval, CI: 2.46 - 29.07, p = 0.02). The incidence of postoperative complications did not change between the two groups (Risk Ratio, RR = 0.86, 95% CI: 0.66 - 1.13, p = 0.27). There were no significant differences regarding postoperative length of hospital stay between simple or complex segmentectomies (MD = -0.02, 95% CI: 0.56 - 0.51, p = 0.93).
CONCLUSIONS
Simple and complex segmentectomies have comparable postoperative outcomes; in particular, postoperative complication rates and length of hospital stay were similar. Complex segmentectomies were associated with a longer operative time.

BACKGROUND
The goal of mastectomy is remove all of the glandular breast tissue (BGT) without compromising skin flaps viability. The purpose of this systematic review was to localize and/or estimate the amount of residual BGT (rBGT) after mastectomy and to identify factors that could be related to rBGT and/or residual disease.
METHODS
We conducted a PubMed search. The report was subdivided according to the method used to evaluate the presence of rBGT. A total of 16 publications were included in our final report. Two main methods for identifying rBGT included imaging (i.e., MRI scan) and histological evaluation at the time of mastectomy.
RESULTS
The rate of rBGT was reported in up to 100% of the patients and was found to be associated mainly with the type of surgical resection, indication, and surgeon's expertise. Residual breast tissue can be found in all areas of the remaining chest wall, mostly in the skin-flaps, and more frequently underneath the nipple-areola complex.
