Myoepithelial carcinoma of the head and neck is a rare malignant tumor that usually arises from the salivary glands but rarely from the larynx. Here, we describe 11 cases (one treated by us and 10 previously published) of laryngeal myoepithelial carcinoma. Our patient was a 60-year-old male who initially presented with hoarseness and throat pain. The patient had suffered from continuing hoarseness and throat pain for one month before he consulted an otorhinolaryngologist. Computed tomography (CT) scan showed a polypoid tumor involving the right vocal cords. Biopsy was performed, and the disease was pathologically diagnosed as myoepithelial carcinoma of the larynx by hematoxylin-eosin and immunohistochemical staining. The total follow-up period was 15 months. Repeated laryngoscopies or CT scans revealed no recurrence or residual lesion during the post-surgical course.

Review
The presence of tumor-infiltrating lymphocytes (TIL) in the tumor microenvironment has been demonstrated to be of prognostic value in various cancers. In this systematic review and meta-analysis, we investigated the prognostic value of TIL in laryngeal squamous cell carcinoma (LSCC). We performed a systematic search in PubMed for publications that investigated the prognostic value of TIL in LSCC. A meta-analysis was performed including all studies assessing the association between TIL counts in hematoxylin-eosin (HE)-stained sections, for CD8+ and/or CD3+/CD4+ TIL and overall survival (OS) or disease-free survival (DFS). The pooled meta-analysis showed a favorable prognostic role for stromal TIL in HE sections for OS (HR 0.57, 95% CI 0.36-0.91, = 0.02), and for DFS (HR 0.56, 95% CI 0.34-0.94, = 0.03). High CD8+ TIL were associated with a prolonged OS (HR 0.62, 95% CI 0.4-0.97, = 0.04) and DFS (HR 0.73, 95% CI 0.34-0.94, = 0.002). High CD3+/CD4+ TIL demonstrated improved OS (HR 0.32, 95% CI 0.16-0.9, = 0.03) and DFS (HR 0.23, 95% CI 0.10-0.53, = 0.0005). This meta-analysis confirmed the favorable prognostic significance of TIL in LSCC. High stromal TIL evaluated in HE sections and intra-tumoral and stromal CD3+, CD4+ and/or CD8+ TIL might predict a better clinical outcome.

Head & Neck Jul 2021In this systematic review, we aim to identify prognostic imaging variables of recurrent laryngeal or hypopharyngeal carcinoma after chemoradiotherapy. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
In this systematic review, we aim to identify prognostic imaging variables of recurrent laryngeal or hypopharyngeal carcinoma after chemoradiotherapy.
METHODS
A systematic search was performed in PubMed and EMBASE (1990-2020). The crude data and effect estimates were extracted for each imaging variable. The level of evidence of each variable was assessed and pooled risk ratios (RRs) were calculated.
RESULTS
Twenty-two articles were included in this review, 17 on computed tomography (CT) and 5 on magnetic resonance imaging (MRI) variables. We found strong evidence for the prognostic value of tumor volume at various cut-off points (pooled RRs ranging from 2.09 to 3.03). Anterior commissure involvement (pooled RR 2.19), posterior commissure involvement (pooled RR 2.44), subglottic extension (pooled RR 2.25), and arytenoid cartilage extension (pooled RR 2.10) were also strong prognostic factors.
CONCLUSION
Pretreatment tumor volume and involvement of several subsites are prognostic factors for recurrent laryngeal or hypopharyngeal carcinoma after chemoradiotherapy.

Meta-Analysis Review
: To assess the prognostic utilities of various risk factors for laryngeal squamous cell carcinoma. : Six databases were searched to January 2022. Hazard ratios for overall survival and disease-free survival were collected and study characteristics were recorded. The risk of bias was evaluated using the Newcastle-Ottawa scale. : Twenty-eight studies involving 32,128 patients were finally included. In terms of overall survival, older age, a history of alcohol consumption, a high Charlson comorbidity index score, a high TNM stage (III and IV), a high tumor stage (III and IV), nodal involvement, poor pathological differentiation, primary chemoradiotherapy and radiotherapy were associated with increased risks of death. In terms of disease-free survival, older age (≥60 years), TNM stages III and IV, tumor stages III and IV, supraglottic tumors, and nodal involvement all increased the risk of death. : The TNM stage importantly predicts overall survival, and tumor location predicts the disease-free survival of patients with laryngeal squamous cell carcinoma. Of patients with risk factors, the Charlson comorbidity index usefully predicts overall survival.

Review
Narrow-band imaging (NBI) represents a valid aid in laryngeal squamous cell carcinoma (LSCC) diagnosis for detecting vascular changes. However, LSCC and laryngeal papillomatosis (LP) show similar vascular patterns that may lead to misdiagnosis and improper treatment. This review aims to deepen this NBI limit in order to stress a careful preoperative evaluation of laryngeal lesions. The research was carried out on PubMed, Web of Science and Scopus databases using specific keywords. The topic of research was assessed by these parameters: accuracy, sensitivity, specificity, and positive and negative predictive values. This review included only five articles: they demonstrated that NBI is better than white-light endoscopy in detecting LSCC and LP. They also reported that LP is frequently mistaken for LSCC, resulting in high rates of false positives using NBI. This is the first review that emphasized this NBI limitation in distinguishing between LP and LSCC in cases of a type V pattern of intraepithelial papillary capillary loop. Although NBI application increased the rate of early cancer detection, LP reduces NBI accuracy. This drawback may lead to misdiagnosis and improper treatment. Our advice is to be careful in cases of type V pattern on NBI and to research LP epithelial and clinical features because it could be a pitfall.

Review
OBJECTIVE
To investigate epidemiological, clinical and oncological outcomes of patients with laryngeal verrucous carcinomas (LVC).
METHODS
Two independent authors investigated PubMed, Scopus and Cochrane Library for studies dedicated to epidemiological, clinical and oncological outcomes of patients with LVC. The following outcomes were investigated with PRISMA criteria: age; gender; tobacco/alcohol consumption; HPV infection; anatomical, pathological, therapeutic and survival outcomes. Studies were analyzed for bias through a validated clinical tool.
RESULTS
Of the 212 identified articles, 15 retrospective studies and one prospective uncontrolled study met our inclusion criteria. Three studies reported findings from national databases. The males/females ratio is 9/1. Mean age was 60.3 years, which was younger compared to other laryngeal malignancies. The alcohol, cigarette overuse and the HPV status of patients were lacking in most studies. Glottis and supraglottis were the most common anatomical locations, corresponding to 78.7% and 12.4% of cases, respectively. The main therapeutic approaches consisted of surgery, radiotherapy, surgery followed by radiotherapy. Treatments reported 5-year overall survival and disease-specific survival of 86.3 and 90.8, respectively. The 5- and 10-year local control rate were 83.6 and 72.6, respectively. The 10-year disease-specific survival was 80.2. Heterogeneity between studies was found for inclusion criteria, comorbidity data, and treatments.
CONCLUSION
LVC is a rare laryngeal cancer associated with better survival and recurrence outcomes than laryngeal squamous cell carcinoma. The role of radiotherapy in the treatment regimen needs to be investigated in future prospective controlled studies.

Meta-Analysis Review
BACKGROUND
Tea and coffee are the most commonly consumed beverages in the worldwide. The relationship between tea and coffee consumption on the risk of laryngeal cancer was still unclear.
METHODS
Relevant studies were identified by searching electronic database (Medline and EMBASE) and reviewing the reference lists of relevant articles until Oct. 2013. Observational studies that reported RRs and 95% CIs for the link of tea and coffee consumption on the risk of laryngeal cancer were eligible. A meta-analysis was obtained to combine study-specific RRs with a random-effects model.
RESULTS
A total of 2,803 cases and 503,234 controls in 10 independent studies were identified. The overall analysis of all 10 studies, including the case-control and cohort studies, found that tea drinking was not associated with laryngeal carcinoma (RR = 1.03; 95% CI: 0.66-1.61). However, coffee consumption was significantly associated with the laryngeal carcinoma (RR = 1.47; 95% CI: 1.03-2.11). A dose-response relationship between coffee intake and laryngeal carcinoma was detected; however, no evidence of dose-response link between tea consumption and laryngeal carcinoma risk was detected.
CONCLUSIONS
The results from this meta-analysis of observational studies demonstrate that coffee consumption would increase the laryngeal cancer risk, while tea intake was not associated with risk of laryngeal carcinoma.

Review
BACKGROUND
Laryngeal carcinoma is a primary malignant tumor originating from the laryngeal mucosa, and its pathogenesis is not fully understood. It is a rare type of cancer that shows a downward trend in the 5-year survival rate. In clinical practice, dysregulated microRNAs are often observed in patients with laryngeal cancer. In recent years, an increasing number of studies have confirmed that the strong biomarker potential of microRNAs. We conducted a systematic review and meta-analysis to identify and highlight multiple microRNAs as biomarkers for disease prognosis in patients with laryngeal cancer.
METHODS
We actively searched the systematic reviews in PubMed, Embase, Web of Science and The Cochrane Library to select the studies that met the proposed guidelines. A total of 5307 patients with laryngeal cancer were included in this study to evaluate the association between microRNAs expression levels and patient outcomes. For overall survival in the clinical stage, a hazard ratio (HR) and corresponding 95% confidence interval (CI) are calculated to assess the effect of survival.
RESULTS
A total of 36 studies on microRNAs and laryngeal cancer recovery were included in this meta-analysis. The selected endpoints for these studies included overall survival (OS) and disease-free survival (DFS).The comorbidities of overexpression and underexpression of microRNAs were 1.13 (95% CI 1.06-1.20, P < 0.05) and 1.10 (95% CI 1.00-1.20, P < 0.05), respectively.
CONCLUSION
MiRNA-100, miRNA-155, miRNA-21, miRNA-34a, miRNA-195 and miR-let-7 are expected to be potential noninvasive and simple markers for laryngeal cancer.

BACKGROUND
Head and neck (H&N) squamous cell carcinoma (SCC) is a significant contributor to worldwide mortality and morbidity. Human papillomavirus (HPV) has been linked with H&N cancer and HPV-positive H&N SCC have been shown to have better survival outcomes.
OBJECTIVE
To evaluate the effect of human papillomavirus (HPV) on laryngeal carcinoma (LSCC) survival outcomes and prognosis.
METHOD
A systematic review and meta-analysis were performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. LSCC was confirmed based on histopathology, and HPV status was confirmed by either polymerase chain reaction, immunohistochemistry, and/or in-situ hybridization.
RESULTS
There were 1214 studies which were identified, of which 14 studies were eligible for our review. A total of 2,578 cases of LSCC were included in analysis with 413 (16.0%) HPV-positive. Overall survival (OS) was not significant for HPV-positive LSCC in first five years (year one: OR 1.44 p=0.13; year two: OR 1.24 p=0.30; year three: OR 1.01 p=0.97; year four: OR 1.13 p=0.63; year five: OR 1.01 p=0.98). Disease-free survival (DFS) was similarly not significant for HPV-positive LSCC (year one: OR 1.08 p=0.68; year two: OR 1.22, p=0.31; year three: OR 1.13, p=0.69; year four: OR 0.93, p=0.80 and year five: OR 1.42, p=0.30). When studies are sub-divided into global regions, Chinese studies had better HPV-positive survival compared to North American studies in year five (OR 1.84 vs OR 0.46, p=0.04).
CONCLUSION
This is the first study of its kind to evaluate the survival impact of HPV-positive LSCC patients. Unlike oropharyngeal cancer, HPV status does not make a difference to OS or DFS in LSCC. This supports data that HPV is not a prognostic factor in squamous carcinoma of the larynx.

Meta-Analysis Review
BACKGROUND
The role of open conservation (partial) laryngeal surgery in radiorecurrent laryngeal cancers is unclear, and the procedure is not widely accepted or practiced. The objective of this review was to assess the oncologic and functional outcomes of partial laryngectomy in radiorecurrent tumors of the larynx reported in the literature.
METHODS
The systematic review was performed using independently developed search strategies and included Medline, Embase, Zetoc, conference proceedings, and, when appropriate, a manual search. Inclusion criteria for the articles were set a priori. All included articles were subjected to quality assessment. Pooled estimates of local control at 24 months and of disease-free and overall survival rates were calculated using both a fixed-effects model (inverse square) and a random-effects model (DerSimonian-Laird).
RESULTS
The search identified 401 publications, of which 26 studies satisfied all inclusion criteria. Ten studies had a quality score ≥6 (good), and 16 had a score of 4 or 5 (fair). The pooled estimates of oncologic outcomes using the random-effects model were as follows: The local control rate at 24 months for 560 patients was 86.9% (95% CI, 84%-89.5%), the disease-free survival rate for 352 patients was 91.2% (95% CI, 88.2%-93.9%), and the overall survival rate for 360 patients was 83.1% (95% CI, 79.1%-86.7%). Decannulation of tracheostomy occurred in 95.1% (95% CI, 92.6%-97.2%) of the patients who were analyzed (n = 315), whereas the pooled mean larynx preservation rate was 83.9% (95% CI, 80.7%-87%; n = 502)
CONCLUSIONS
The current results indicated that open partial laryngectomies are oncologically sound procedures in the salvage setting and have a high larynx preservation rate.
