Review
OBJECTIVES
In this systematic review, we aimed to evaluate the clinicopathological and prognosis data of patients with salivary gland myoepithelial carcinoma.
MATERIALS AND METHODS
MEDLINE/PubMed, Scopus, and Embase search was performed with the keywords "myoepithelial carcinoma" "malignant myoepithelioma," and "salivary glands." Primary salivary glands myoepithelial carcinoma that fulfilled the World Health Organization diagnostic criteria were included. The Joanna Briggs Institute tool was used to assess the risk of bias.
RESULTS
Forty-three studies (71 patients) met the inclusion criteria. The patients showed a mean age of 56.4 ± 19.6 years with no sex predilection. The parotid was the most affected gland (49.3%). The tumor presented as an asymptomatic (65.1%) mass (84%). The most common histological findings were the presence of clear tumor cells (39.7%) and multinodular growth patterns (60.7%). Multivariate analysis showed plasmacytoid cell type (p = 0.010) and solid growth pattern (p = 0.003) were related to decreased disease-free survival. Surgery alone was the most used treatment (53.5%). Patients with a combination of treatments showed a longer disease-free survival (p = 0.049). The 2-year and 5-year overall survival rates were 67.5% and 46.1%, respectively.
CONCLUSION
Salivary gland myoepithelial carcinoma showed no sex predilection, with a higher incidence in the parotid gland. Cell type, growth pattern, and treatment type may be related to a lower disease-free survival. Overall, salivary gland myoepithelial carcinoma presented low recurrence and metastasis rates. Registration and protocol: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist and registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42022311512).

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31 articles including 47 cases of malignant breast myoepithelioma and 3 other unpublished cases managed in our establishment were included in this systematic review.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.

Meta-Analysis Review
This study is a systematic review and meta-analysis to assess the overexpression rate of HER2 in patients with salivary gland tumors. We included peer-reviewed publications from 1995 to 2020, indexed in medical databases, using search terms such as "human epidermal growth factor receptor 2 (HER2)" and "salivary gland tumors", and extracted relevant data. The extracted data were analyzed with RevMan 5.3 software. Intra-and intergroup post hoc analyses of outcome variables were performed using t-tests, and the rates of HER2 positivity among studies were evaluated. 80 studies were included in the analysis. The positive rates of HER2 ranged from 3.3% to 84.0% and 1% to 9% in malignant and benign subtypes, respectively. The highest HER2 overexpression rate among malignant tumors was in salivary ductal carcinomas (SDC), with a 45% positive rate (CI 95%: 21.9-70.3%). Mucoepidermoid carcinoma (MEC) had the highest positive rate of 84% (CI 95%: 74.1-90.0%). Among benign salivary gland tumors, the highest rate was found in myoepithelioma, with a positive rate of 9% (CI 95%: 1.7-33.6%). The highest rate of HER2 overexpression is present in malignant subtypes of salivary gland tumors, more specifically in salivary ductal carcinoma, mucoepidermoid carcinomas, salivary duct carcinoma in situ, and carcinoma ex pleomorphic adenoma.

Review
Epithelial-myoepithelial carcinoma of the maxillofacial and sinonasal region: a systematic review of presenting characteristics, treatment modalities, and associated outcomes.
Epithelial-myoepithelial carcinoma (EMC) is a rare salivary gland malignancy. Controversy exists in the literature regarding the effectiveness of treatment modalities employed in the management of EMC. This systematic review was undertaken to understand the presenting characteristics of EMC and identify the most common treatment modalities and their associated outcomes, in order to help guide an evidenced-based approach to the algorithm of care. The MEDLINE (PubMed) and Embase databases were searched (up to February 23, 2022), and the review was performed in accordance with the PRISMA statement. Fifty-seven studies (51 case reports and six case series) describing 91 cases of EMC were included in this review. In the included studies, a slow-growing painless mass was the most common presenting clinical feature. EMC was most frequently treated with surgery alone (65%). Local disease recurrence occurred in 24% of the cases and metastatic disease in 11%. A positive surgical margin was found to be associated with a higher risk of recurrence (P < 0.001), while adjuvant radiotherapy was associated with a decreased risk of local disease recurrence (P = 0.034). Metastatic disease and multimodal therapy were found to be associated with decreased disease-free and overall survival (all P < 0.05). The current literature supports surgery with clear margins as the mainstay of treatment for EMC of the salivary and seromucous glands of the head and neck. In certain situations, radiotherapy may improve disease-free survival.

INTRODUCTION
Myoepithelial carcinoma (MEC) is an extremely rare low grade salivary gland neoplasm [1-4]. A surgical resection is considered as corner stone of therapy. Role of adjuvant therapy is not clear.
METHODOLOGY
We performed systematic review and individual patient data analysis of 691 patients to look into the impact of adjuvant therapy and different prognostic variable for MEC.
RESULTS
Data of 691 individual patients were retrieved from 340 publications. Median age of presentation was 56 years (Range: 0-103 years) with a trend of increasing incidence for increase in age. Major salivary glands (36.4%) were the commonest sub-site followed by minor salivary glands, skin and soft tissue, and breast. Median PFS and OS of entire cohort was 48 months (95% CI: 30-65 months) and 167 months (95% CI: 82-251 months). In univariate analysis A R0 resection was associated with significantly better PFS and OS. Median PFS and OS were significantly worse for patients with tumour size >5 cm compared to smaller tumours and for patients with a mitotic index >10/10 high power field (hpf) compared to lower mitotic index. Adjuvant radiation was found to reduce loco-regional recurrence. Adjuvant radiation and chemotherapy both were associated with negative impact on survival in univariate analysis. This negative impact on survival was lost in multivariate analysis.
CONCLUSION
MEC appears to be a low grade malignancy with good survival outcome. A R0 resection should be the standard of care. Adjuvant radiation should be considered for patients with adverse risk features to improve loco-regional disease control.

BACKGROUND
Myoepithelioma of the soft tissue (MES) is a rare neoplasm, and available literature includes few studies with small sample sizes, thus limiting the comprehension of this disease. Hence, a systematic review was performed to summarize the available information on MES patients evaluated for surgical treatment.
METHODS
The MEDLINE/PubMed, EMBASE and SCOPUS databases were reviewed for eligible studies in January 2019. Inclusion criteria were: patients with MES; indication for wide resection or amputation; observational studies; articles published from 1997 to 2018; English language; reporting of outcome measures such as overall survival (OS), disease-free survival (DFS), recurrence, metastases. Studies not including humans were excluded. Quality appraisal was performed using the Methodological Index for Non-Randomized Studies (MINORS) tool. A narrative synthesis of included studies was conducted, a formal meta-analysis being unfeasible.
RESULTS
Overall, 10 eligible studies including 233 MES patients were identified. The most frequent tumor sites were the limbs and trunk. Most patients underwent surgical treatment, with R0 resection margin rates ranging from 24% to 78%. During follow-up, local recurrence rates ranged from 17% to 50, and distant metastasis rates varied 8%-48%. At 5 years, OS rates ranged from 8% to 94% and DFS rates from 11% to 40%. The average MINORS score was 9.1 (range: 6-11).
CONCLUSIONS
Surgical resection was often sub-optimal. The long-term prognosis was poor, with a non-negligible rate of disease recurrence and metastasis. On average, the quality of available information is moderate. The centralization of patient information in large international registries is warranted to provide a better understanding of MES biology and ultimately improve patient outcomes.
