[PMID: 39101350 DOI: 10.1002/ohn.932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 07/02/2024] [Accepted: 07/20/2024] [Indexed: 08/06/2024]
Abstract
OBJECTIVE Identify the proportion of patients undergoing elective neck dissection (END) in surgically managed supraglottic squamous cell carcinoma (SCCa), assess associations between patient, tumor, and treatment factors with END, and assess associations between neck management and overall survival (OS). STUDY DESIGN Retrospective study. SETTING National Cancer Database (NCDB) 2019 Participant User File. METHODS Patients with previously untreated, clinically node-negative (cN0) supraglottic SCCa treated with partial laryngectomy were queried from NCDB. Patients without known neck management and who underwent total laryngectomy were excluded. Patient and tumor factors associated with END were evaluated by logistic regression analysis. Univariable Cox proportional hazard analysis was used to examine associations between patient factors and OS, and factors with P < .05 were included on multivariable analysis. RESULTS A total of 1352 patients met eligibility criteria. Eight hundred eleven (60%) patients had END performed with occult nodal metastasis identified in 177 (22%) patients. END was more likely to be performed at academic centers than nonacademic centers (odds ratio: [1.66], 95% confidence interval [CI]: 1.32-2.09, P < .001). On multivariable analysis, patients who underwent adjuvant radiation had worse OS (hazard ratio [HR]: 1.45, 95% CI: 1.13-3.29, P = .017). END was associated with improved OS overall on univariable analysis (HR: 0.83, 95% CI: 0.69-0.98, P = .026), but not on multivariable analysis. CONCLUSION In this NCDB study, 22% of cN0 supraglottic SCCa patients had occult nodal metastatic disease. Despite this, 40% of patients do not receive END at the time of primary resection. Patients who receive END for supraglottic SCCa are more likely to avoid adjuvant radiation without impacting OS.

Abstract
Cancer is a persistent and urgent health problem that affects the entire world. Not long ago, regulatory biomolecules referred to as long noncoding RNAs (lncRNAs) might have value for their innate abundance and stability. These single-stranded RNAs potentially interfere with several physiological and biochemical cellular processes involved in many human pathological situations, particularly cancer diseases. Ferritin heavy chain1 pseudogene 3 (FTH1P3), a lncRNA that is ubiquitously transcribed and belongs to the ferritin heavy chain (FHC) family, represents a novel class of lncRNAs primarily found in oral squamous cell carcinoma. Further research has shown that FTH1P3 is involved in other malignancies such as uveal melanoma, glioma, esophageal squamous cell carcinoma, non-small cell lung cancer, breast cancer, laryngeal squamous cell carcinoma, and cervical cancer. Accordingly, FTH1P3 significantly enhances cancer symptoms, including cell proliferation, invasion, metastasis, chemoresistance, and inhibition of apoptosis through many specific mechanisms. Notably, the clinical data significantly demonstrated the association of FTH1P3 overexpression with poor prognosis and poor overall survival within the examined samples. Here, we summarize all the research published to date (13 articles) on FTH1P3, focusing on the biological function underlying the regulatory mechanism and its possible clinical relevance.

Sci Rep 2023; 13:9734. [PMID: 37322055 PMCID: PMC10272182 DOI: 10.1038/s41598-023-35627-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 05/21/2023] [Indexed: 06/17/2023] Open
Abstract
Most recent survival prediction has been based on TNM staging, which does not provide individualized information. However, clinical factors including performance status, age, sex, and smoking might influence survival. Therefore, we used artificial intelligence (AI) to analyze various clinical factors to precisely predict the survival of patients with larynx squamous cell carcinoma (LSCC). We included patients with LSCC (N = 1026) who received definitive treatment from 2002 to 2020. Age, sex, smoking, alcohol consumption, Eastern Cooperative Oncology Group (ECOG) performance status, location of tumor, TNM stage, and treatment methods were analyzed using deep neural network (DNN) with multi-classification and regression, random survival forest (RSF), and Cox proportional hazards (COX-PH) model for prediction of overall survival. Each model was confirmed with five-fold cross validation, and performance was evaluated using linear slope, y-intercept, and C-index. The DNN with multi-classification model demonstrated the highest prediction power (1.000 ± 0.047, 0.126 ± 0.762, and 0.859 ± 0.018 for slope, y-intercept, and C-index, respectively), and the prediction survival curve showed the strongest agreement with the validation survival curve, followed by DNN with regression (0.731 ± 0.048, 9.659 ± 0.964, and 0.893 ± 0.017, respectively). The DNN model produced with only T/N staging showed the poorest survival prediction. When predicting the survival of LSCC patients, various clinical factors should be considered. In the present study, DNN with multi-class was shown to be an appropriate method for survival prediction. AI analysis may predict survival more accurately and improve oncologic outcomes.

Lan L, Cao H, Zhao L, Cui W, Wang B. PTPN12 down-regulated by miR-146b-3p gene affects the malignant progression of laryngeal squamous cell carcinoma. Open Med (Wars) 2023; 18:20230727. [PMID: 37333450 PMCID: PMC10276617 DOI: 10.1515/med-2023-0727] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Revised: 03/31/2023] [Accepted: 05/07/2023] [Indexed: 06/20/2023] Open
Abstract
Laryngeal squamous cell carcinoma (LSCC) is a common malignancy among men in the anatomical position of head and neck. Hoarseness, pharyngalgia, and dyspnea are common symptoms. LSCC is a complex polygenic carcinoma that is caused by many factors involving polygenic alteration, environmental pollution, tobacco, and human papillomavirus. Classical protein tyrosine phosphatase nonreceptor type 12 (PTPN12) has been extensively studied to decipher its mechanism as a tumor suppressor gene in various human carcinomas; however, there is no comprehensive elucidation of the PTPN12 expression and its regulatory mechanisms in LSCC. As such, we expect to provide new insights for finding new biomarkers and effective therapeutic targets in LSCC. Immunohistochemical staining, western blot (WB), and quantitative real-time RT-PCR (qRT-PCR) were used for the messenger RNA (mRNA) and protein expression analyses of PTPN12, respectively. 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, clone formation, transwell migration, and transwell invasion assays were used to assess the proliferation, migration, and invasion ability of LSCC cells. Online prediction and design software tools (http://www.targetscan.org/ and http://www.microRNA.org) were used to predict associated miRNA. Studying the targeted regulatory relationship between miR-146b-3p and PTPN12 was based on dual luciferase reporter gene analysis. qRT-PCR was used to assess miR-146b-3p expression in LSCC. miR-146b-3p inhibitor and mimic were transfected, followed by qRT-PCR and WB assays to detect the expression of PTPN12. The gain and loss functional experiments were used to investigate the effects of miR-146b-3p transfection on the proliferation, migration, and invasion of tumor cells. Online bioinformatics prediction software (https://cn.string-db.org/ and https://www.genecards.org/) was used to determine potential downstream target genes of PTPN12. qRT-PCR and WB analyses were used to assess the mRNA and protein expression levels of target genes. Our study showed significantly decreased mRNA and protein expression levels of PTPN12 in LSCC compared with the adjacent normal tissues. The lower PTPN12 mRNA expression was correlated with pathological differentiation, and lower PTPN12 protein expression was correlated with the TNM stage in LSCC tissues. The subsequent in vitro functional analyses showed the inhibitory effect of PTPN12 over-expression on the proliferation, migration, and invasiveness abilities of LSCC cell line. Using online prediction and design software, miR-146b-3p was searched to target PTPN12. The miR-146b-3p was expressed at a high level in LSCC tissues and cell lines. Luciferase reporter assay exhibited that miR-146b-3p inhibited the luciferase activity of PTPN12 markedly. The functional analyses showed the tumor-promoting role of miR-146b-3p on the proliferation, migration, and invasiveness abilities of LSCC cell. Furthermore, co-transfection of cells with miR-146b-3p and PTPN12 significantly restored the inhibitory effect of PTPN12 on LSCC cell growth, migration, and invasiveness. This phenomenon unveiled that miR-146b-3p regulated the proliferation, migration, and invasion of LSCC cells by targeting PTPN12. EGFR and ERBB2 were selected as the downstream-regulation target genes. Up-regulation of PTPN12 significantly suppressed EGFR expression. Accordingly, the miR-146b-3p mimic significantly up-regulated the EGFR expression. However, up-regulation of PTPN12 and miR-146b-3p mimic suppressed ERBB2 protein expression but induced its gene expression. Down-regulation of PTPN12 is associated with up-regulation of miR-146b-3p in LSCC. Moreover, PTPN12 serves as a tumor suppressor gene through regulating the proliferation, migration, and invasion of LSCC cells. miR-146b-3p/PTPN12 axis is expected to be a novel therapeutic target in LSCC.

Abstract
Mitochondrial permeability transition (MPT)-driven necrosis, a type of programmed cell death, has recently gained much attention in a variety of tumor types. Few studies have been performed to explore the role of MPT-driven necrosis-related lncRNAs (MPTDNRlncRNAs) in laryngeal squamous cell carcinoma (LSCC). The purpose of our study is to screen MPTDNRlncRNAs with prognostic value and to explore their potential roles in LSCC. The RNA-sequencing data and the corresponding clinical data of LSCC patients were obtained from the TCGA database, and those MPT-driven necrosis-related genes were extracted from the Gene Set Enrichment Analysis (GSEA) database. We identified MPTDNRlncRNAs differentially expressed in LSCC. Also, we gained MPT-driven necrosis-related prognostic lncRNAs by univariate cox regression analysis. A novel MPTDNRlncRNAs signature was constructed by LASSO-COX. The accuracy and utility of the MPTDNRlncRNAs signature were evaluated via a variety of statistical methods. Multiple bioinformatics tools were used to explore the underlying difference in biological functions and signaling pathways between the different risk groups. The expressions levels of MPTDNRlncRNAs were analyzed using RT-qPCR in LSCC cell line. Finally, we identified A 5 MPTDNRlncRNAs signature in LSCC. Our prognostic model demonstrated an efficient ability to predict outcomes. The proportion difference of immune cells in the subgroups were significant, such as M0 macrophage and T follicular helper cells. The in vitro experiments suggested that our MPTDNRlncRNAs were significantly different. This 5 MPTDNRlncRNAs signature is a prognostic biomarker for LSCC. More importantly, the novel biologic prognostic model can be utilized for personalized immunotherapy in LSCC patients.

Laryngoscope Investig Otolaryngol 2022; 7:1951-1962.

Abstract
Introduction Laryngeal squamous cell cancer (LSCC) is a highly malignant tumor originating from the respiratory system. Circular RNAs have been reported to be associated with the treatment and prognosis of a variety of cancers, including LSCC. Methods The expression of circBFAR, miR-31-5p, and collagen type V alpha 1 chain (COL5A1) in LSCC tissues and cells was detected by quantitative real-time polymerase chain reaction. Cell counting kit 8 and 5-Ethynyl-2'-deoxyuridine assays were used to detect cell proliferation. Wound healing assay and transwell assay were used to test cell migration and invasion, respectively. The protein expression in LSCC cells was detected with western blot. The relationships between miR-31-5p and circBFAR or COL5A1 were identified by dual-luciferase reporter assay, RNA-pull down assay, and immunoprecipitation assay. The effect of circBFAR on tumor growth in vivo was detected by tumor xenograft mice experiment. The protein expression of COL5A1 and KI-67 in LSCC tissues was measured by immunohistochemistry assay. Results CircBFAR was increased in LSCC tissues and cells, and was related to advanced clinical stage and overall survival of LSCC patients. The cell viability and proliferation were inhibited by circBFAR knockdown and silencing of circBFAR blocked migration and invasion of LSCC cells. CircBFAR knockdown suppressed cell tube formation, and the protein expression of KI-67, matrix metallopeptidase 2 (MMP2), and vascular endothelial growth factor A (VEGFA) in LSCC cells. MiR-31-5p was the target of circBFAR, and the inhibitory effects of circBFAR deficiency on viability, proliferation, migration, invasion, tube formation and the protein expression of KI-67, MMP2, and VEGFA in LSCC cells were rescued by miR-31-5p downregulation. COL5A1 was negatively regulated by miR-31-5p, and was boosted in LSCC tissues and cells. COL5A1 overexpression reversed the inhibitory effects of miR-31-5p on LSCC cells. CircBFAR insufficiency hindered tumor growth in vivo. Conclusion CircBFAR, miR-31-5p, and COL5A1 in LSCC progression might provide novel therapeutic targets for LSCC clinical intervention.

Abstract
INTRODUCTION Federated learning has the potential to perfrom analysis on decentralised data; however, there are some obstacles to survival analyses as there is a risk of data leakage. This study demonstrates how to perform a stratified Cox regression survival analysis specifically designed to avoid data leakage using federated learning on larynx cancer patients from centres in three different countries. METHODS Data were obtained from 1821 larynx cancer patients treated with radiotherapy in three centres. Tumour volume was available for all 786 of the included patients. Parameter selection among eleven clinical and radiotherapy parameters were performed using best subset selection and cross-validation through the federated learning system, AusCAT. After parameter selection, β regression coefficients were estimated using bootstrap. Calibration plots were generated at 2 and 5-years survival, and inner and outer risk groups' Kaplan-Meier curves were compared to the Cox model prediction. RESULTS The best performing Cox model included log(GTV), performance status, age, smoking, haemoglobin and N-classification; however, the simplest model with similar statistical prediction power included log(GTV) and performance status only. The Harrell C-indices for the simplest model were for Odense, Christie and Liverpool 0.75[0.71-0.78], 0.65[0.59-0.71], and 0.69[0.59-0.77], respectively. The values are slightly higher for the full model with C-index 0.77[0.74-0.80], 0.67[0.62-0.73] and 0.71[0.61-0.80], respectively. Smoking during treatment has the same hazard as a ten-years older nonsmoking patient. CONCLUSION Without any patient-specific data leaving the hospitals, a stratified Cox regression model based on data from centres in three countries was developed without data leakage risks. The overall survival model is primarily driven by tumour volume and performance status.

Abstract
Laryngeal Squamous Cell Carcinoma (LSCC) is one of the most common malignancy in Head and neck cancer for which the mechanism underlying its metastasis is poorly understood. Myosin X, a molecular motor in cells has been demonstrated to play an important role in cell migration. However, whether Myosin X is involved in the metastasis of LSCC remains unclear. To investigate the expression of Myosin X and its implication in the metastasis of LSCC, we recruited 30 patients with LSCC and 6 patients with vocal cord polyp range from October 2016 to October 2018. Tissue samples were obtained during surgery and the expression of Myosin X, Cortactin, MMP2, MMP9, E-cadherin, and β-catenin in tissue samples were evaluated by RT-PCR, Western blot, immunohistochemistry or ELISA. Patients with LSCC were further followed-up 2 year after surgery for metastasis analysis. We found that the level of Myosin X, Cortactin, MMP2, and MMP9 was much higher in poorly differentiated LSCC compared to that in moderately and highly LSCC, as well as the control tissues. In contrast, the expression of epithelial-mesenchymal transition related marker, E-cadherin, and β-catenin, were much lower in poorly differentiated LSCC tissues compared to that in moderately and highly differentiated LSCC tissues, as well as the control tissues. Moreover, the expression of Myosin X was positively correlated with Cortactin, MMP2, and MMP9 levels. Increased expression of Myosin X in LSCC tissues was related to higher risk of metastasis. In conclusion, our findings showed that. Myosin X augments the expression of Cortactin, MMP2 and MMP9, which could upregulate the cell migration and the matrix degradation, and consequently reduce the expression of E-cadherin and β-catenin, thereby activating epithelial-mesenchymal transformation and promoting the metastasis of LSCC. Targeting Myosin X may have potential therapeutic effect in the metastasis of LSCC.

The Expression of the Long Noncoding RNA AFAP1-AS1 in Laryngeal Carcinoma Affects the Proliferation, Invasion, Migration, and Apoptosis of TU212 Cell Line. BIOMED RESEARCH INTERNATIONAL 2022; 2022:2337447. [PMID: 35968243 PMCID: PMC9371880 DOI: 10.1155/2022/2337447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 07/18/2022] [Accepted: 07/22/2022] [Indexed: 11/17/2022]
Abstract
Background. lncRNA AFAP1-AS1 has been linked to the pathogenesis of a wide range of tumors. Nevertheless, whether it plays a role in laryngeal carcinoma (LC) remains unclear. Methods. Twenty-nine pairs of LC and related normal tissues were collected for the detection of lncRNA AFAP1-AS1 using qRT-PCR. Correlation of lncRNA AFAP1-AS1 level and clinicopathological characters was assessed by the chi-square test. Impacts of lncRNA AFAP1-AS1 silencing on LC phenotypes were tested in vitro via CCK-8, clone formation, EdU staining, wound healing, flow cytometry, and Transwell assay. Results. Herein, a remarkable elevation of lncRNA AFAP1-AS1 was observed in LC patients. And higher lncRNA AFAP1-AS1 level was correlated to worse clinical pathological characteristics. Moreover, lncRNA AFAP1-AS1 silencing was revealed to repress TU212 malignant phenotypes. Conclusion. Our data suggested that lncRNA AFAP1-AS1 acts as an oncogene of LC in vitro.

Abstract
Objective Several studies were conducted to explore the clinical significance of cyclooxygenase-2 (COX-2) overexpression in laryngeal cancer. However, the associations between COX-2 overexpression and clinicopathological characteristics of laryngeal cancer patients remained unclear. Here, we performed a meta-analysis to eva-TY -40luate the role of COX-2 overexpression in the risk, clinical progression, and progno\sis of laryngeal cancer. Methods The eligible literature was obtained from PubMed, Embase, Web of Science, and China National Knowledge Infrastructure (CNKI) databases. Odds ratio (OR), risk ratio (RR), and 95% confidence interval (CI) were calculated to assess the strength of the associations, and I2 statistics were used to evaluate heterogeneity among studies. Publication bias was detected with Begg’s test and Egger’s test. Results A total of 47 eligible articles were included for the meta-analysis after screening. COX-2 expression levels in the laryngeal cancer patients were significantly higher than those in the normal controls (OR = 11.62, 95% CI: 6.96–19.40, P < 0.05). The pooled results also showed that there were significant correlations between COX-2 overexpression and clinicopathological characteristics (tumor stage, OR = 3.26, 95% CI: 2.13–4.98, P < 0.05; lymph node metastasis, in Asians, OR = 2.35, 95% CI: 1.53–3.60, P < 0.05; recurrence, OR = 10.71, 95% CI: 3.54–32.38, P < 0.05; T stage, in Asians, OR = 2.52, 95% CI: 1.66–3.83, P < 0.05). In addition, significant correlations between COX-2 overexpression and overall survival of laryngeal cancer were found both in Asians and in Caucasians (total, HR = 1.73, 95% CI: 1.23–2.24, P < 0.05; survival in Asians, HR = 2.59, 95% CI: 1.27–3.92, P < 0.05; survival in Caucasians, HR = 1.59, 95% CI: 1.03–2.14, P < 0.05). Conclusions The meta-analysis results suggested that COX-2 overexpression was significantly associated with the increased risk, worse clinicopathological progression, and poorer prognosis of laryngeal cancer.

Abstract
This article describes a method for non-contact local hyperthermal heating of patient's tissue using inductive electromagnetic radiation. Aim: The aim of the study was a theoretical and experimental assessment of the thermal and electromagnetic parameters of the proposed method based on heating of intraoperatively administered, personal, tissue-replacing applicator using induction magnetic field. Methods: Theoretical estimates of the thermal and electromagnetic parameters of this method were performed based on heat conduction equations. An experimental study of the process was carried out using originally designed laboratory inverter and confirmed theoretical calculations. Results: The performed assessments and calculations confirmed the possibility of creating clinically effective hyperthermia in the removed tumor bed by the method of local non-contact intraoperative hyperthermia. Conclusion: The proposed method can be used both independently and in combination with chemo- and radiotherapy, thus reducing the risk of recurrence for locally advanced forms of malignant tumors of the oropharyngeal region after surgical treatment.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is one of the most common malignant tumors of head and neck cancers. In the past decades, although the therapy strategies of LSCC have made considerable improvement, the terrible outcomes of LSCC still bring an enormous burden to the world health care system. Novel therapeutic targets for LSCC are urgently needed. lncRNAs exert important roles in various biological progressions, including LSCC. Here, we aimed to investigate the function of lncRNA PVT1 in LSCC progression and its underlying molecular mechanisms. By conducting multiple experiments, our results showed that lncRNA PVT1 was upregulated in LSCC cell lines and regulated LSCC cell proliferation, apoptosis, and its cell susceptibility to natural killer (NK) cells. Moreover, it was found that lncRNA PVT1 promotes MBNL1 expression to regulate LSCC cellular progression through sponging miR-1301-3p. Our study might provide novel targets for LSCC basic research or clinical management.

Abstract
Abnormal expression of circular RNA (circRNA) is closely related to the occurrence and development of many cancers. By screening the expression of circRNA, we identified a novel circRNA termed as has_circ_0023326 in laryngeal squamous cell carcinoma (LSCC). We verified the expression of circPPFIA1 and found that it was upregulated in LSCC tissues compared to the adjacent normal tissues. Functional studies were carried out to detect the effect of circPPFIA1 expression on the phenotype of LSCC cells. These results suggest that circPPFIA1 knockdown can suppress the proliferation, migration, and invasion of LSCC cells, while circPPFIA1 overexpression can promote these processes. Mechanistically, miR-340-3p was predicted to be the target miRNA sponged by circPPFIA1 as confirmed through the luciferase assay and rescue experiments. In addition, miR-340-3p was found to target ELK1 and inhibit its expression. Taken together, circPPFIA1 promotes the progression of LSCC via the miR-340-3p/ELK1 signaling axis, which may serve as a novel prognostic or therapeutic target for LSCC.

Abstract
Bacteria are among the important factors that play a role in the balance of human health, and their relationship with some tumors has been well established. However, the association between bacteria colonizing the vocal cords and glottic laryngeal squamous cell carcinoma (GLSCC) remains unclear. Here, we investigated whether bacterial communities of the vocal cord mucous membrane play a role in the development of GLSCC. We collected tumor tissue and normal adjacent tissue (NAT) samples from 19 GLSCC patients, and the bacterial communities were compared with control samples (control) from 21 vocal cord polyps using 16S rRNA high-throughput pyrosequencing. We detected 41 phyla, 93 classes, 188 orders, 373 families, and 829 genera in the vocal cord mucous membrane. A comparison of the bacterial communities in the NAT samples showed higher α‐diversity than in the tumor samples. In the tumor samples, seven groups of bacteria, i.e., the phylum Fusobacteria, the class Fusobacteriia, the order Fusobacteriales, the family Fusobacteriaceae, and the genera Fusobacterium, Alloprevotella, and Prevotella, were significantly enriched, as revealed by linear discriminant analysis coupled with effect size measurements (LEfSe). However, bacteria from the phylum Firmicutes were most significantly enriched in the vocal cord polyp tissues. These findings suggest alterations in the bacterial community structure of the vocal cord mucous membrane of GLSCC patients and that seven groups of bacteria are related to GLSCC, indicating that imbalances in bacterial communities increase the risk for the development of GLSCC.

Abstract
Laryngeal squamous cell carcinoma (LSCC), is the second most common malignant cancer of the head and neck after oral cavity cancer. Laryngeal cancer is associated with huge socio-economic burden worldwide. Studies have widely explored the role of non-coding RNAs, especially microRNAs and long non-coding RNAs in pathogenesis of laryngeal cancer. In addition, several studies have explored the mechanism and function of circRNAs. CircRNAs has higher stability and more extensive function models, including combining miRNA as sponge, modifying transcription, and even regulating protein translation have been developed. Therefore, circRNAs is applied as an excellent diagnostic tool and a promising candidate for development of cancer therapies. This study reviews the biogenesis and function of circRNAs, explores potential mechanism of circRNAs in LSCC, and implications and challenges in LSCC research.

Abstract
PURPOSE This study aimed to investigate the relationship between the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), and the systemic immune-inflammation index (SII) with the clinical and pathological parameters of 118 laryngeal cancer patients, as well as their effects on the survival of the disease. METHODS For the calculation of SII, PLR, and NLR, hemogram tests were conducted before treatment. Receiver-operating characteristic (ROC) analysis was used to calculate the cut-off value of SII, NLR, and PLR for overall survival (OS) and disease-free survival (DFS). RESULTS A statistically significant relationship was found between SII and lymphovascular invasion and between NLR and local recurrence, and lymphovascular invasion. In a univariate analysis, SII (p < 0.001) and NLR (p = 0.001) for OS and SII (p < 0.001), PLR (p = 0.043), and NLR (p < 0.001) for DFS were detected as prognostic factors. In a multivariate analysis for OS, SII (HR = 10.54, 95% CI 1.28-86.77; p = 0.029) and extracapsular extension (HR = 3.08, 95% CI 1.15-8.21; p = 0.024) were identified as independent prognostic factors. In a multivariate analysis for DFS, only an extracapsular extension presence (HR = 3.32, 95% CI 1.37-8.08; p = 0.008) was detected as an independent prognostic factor. CONCLUSION In laryngeal cancer, high SII values were determined as poor independent prognostic factors for OS. High SII, NLR, and PRL have been identified as poor prognostic factors in DFS. A correlation was found between NLR and local recurrence, and lymphovascular invasion and between SII with lymphovascular invasion positivity.

Abstract
Some studies state that laryngeal squamous cell carcinoma (LSCC) is associated with possible direct tumor cell seeding to percutaneous endoscopic gastrostomy (PEG) site. However, there is a lack of experimental proof that LSCC tumor tissue can adhere and grow in distant sites. Therefore, we aimed to investigate the growth pattern of LSCC implants on chicken embryo chorioallantoic membrane (CAM) and evaluate possible associations between clinical course of the disease and behavior of experimentally implanted LSCC tumors. Our results show that implanted LSCC tissue survives on CAMs in 95% of cases while retaining essential morphologic characteristics and proliferative capacity of the original tumor. We identified the increased CAM vascularization, an infiltrative growth pattern of the implant and formation of distant isolated metastatic nodes on the CAMs. LSCC tumors with worse differentiation degree (G2 or G3) adhered to the experimental CAMs significantly better than G1. These results facilitate the understanding of tumor biology and allow hypothetisezing that dissemination and direct implantation of LSCC cells into the stomal wall during the pull PEG procedure might be possible.

Abstract
Laryngeal carcinoma is a common head and neck malignancy, however, the molecular mechanism of the disease has not yet been elucidated. The present study aimed to investigate the role of IGF1R antisense imprinted non-protein coding RNA (IRAIN) long non-coding (lnc)RNA in laryngeal carcinoma. In total, specimens of healthy pharynx tissue from 6 healthy individuals, carcinoma tissue and paracancerous tissue from 37 patients with laryngeal carcinoma were used in this study. The single nucleotide polymorphism (SNP) rs8034564 was used to distinguish the two parental alleles of IRAIN. DNA and RNA were extracted from tissue specimens and the IRAIN allelic gene was sequenced. Reverse transcription-quantitative PCR was used to determine the expression levels of IRAIN and Insulin-like growth factor 1 receptor (IGF1R) in laryngeal carcinoma and paracancerous tissue. Bisulfite genomic sequencing was used to determine IRAIN promoter DNA methylation status in laryngeal carcinoma tissue. The expression of IRAIN was di-allelic in healthy pharynx tissue, laryngeal carcinoma tissue and paracancerous tissue. Moreover, IRAIN expression in laryngeal carcinoma tissue was lower compared with paracancerous tissue (P<0.05). IRAIN expression was not associated with age, histological type, tumor stage and grade and lymph node metastasis. IRAIN allelic expression imbalance was present in laryngeal carcinoma and paracancerous tissue, but not in healthy pharynx tissue. SNP analysis (rs8034564) indicated there was an allelic-switch of the two parental alleles. Furthermore, epigenetic analysis revealed no extensive DNA methylation of CpG islands in the IRAIN gene promoter of laryngeal carcinoma. Therefore, it was suggested that IRAIN allele was non-imprinted in laryngeal carcinoma and healthy pharynx tissue. It was also demonstrated that IRAIN may be a potential tumor suppressor in laryngeal carcinoma, and that DNA methylation is not involved in the regulation of IRAIN gene immobilization in laryngeal carcinoma tissue. Thus, detection of IRAIN allelic expression imbalance and aberrant allele-switch may serve as an early diagnostic marker of laryngeal carcinoma.

Accumulating evidence suggests that circular RNAs (circRNAs) may be a key contributor to oncogenesis. Yet, the function of circRNAs in laryngeal squamous cell carcinoma (LSCC) is still not clear. In this study, we examined the function of circRNA_103862 in LSCC progression by analyzing the tissue specimens collected from a patient with LSCC by using different LSCC cell models in vitro and an LSCC xenograft model in nude mice. We found that circRNA_103862 was frequently upregulated in the tissues of LSCC and was correlated with metastasis and prognosis of LSCC patients. Furthermore, circRNA_103862 downregulation could reduce proliferation, migration, and invasion ability of LSCC cells. In terms of mechanism exploration, miR-493-5p was sponged by circRNA_103862. Rescue experiments also showed that circRNA_103862 could achieve a carcinogenic effect by regulating miR-493-5p. Moreover, a luciferase reporter analysis showed that Golgi membrane protein 1 (GOLM1) is a downstream effector of miR-493-5p. In conclusion, our data suggested that circRNA_103862 promotes the proliferation of LSCC through targeting the miR-493-5p/GOLM1 axis, and it might serve as a potential prognosis marker and therapy target for LSCC.

Abstract
OBJECTIVES The purpose of this study was to evaluate the potential predictor of tumor size on rates of overall and disease-free survival (OS and DFS) as determined by postoperative pathologic examination in patients with glottic carcinoma. STUDY DESIGN Retrospective cohort study. SETTING Tertiary care university hospital. SUBJECTS AND METHODS In this study, 1337 consecutive patients with glottic carcinoma who underwent surgical treatment from 2005 to 2010 were retrospectively reviewed. The influence of tumor size that was evaluated by tumor area (tumor length × tumor width) on OS and DFS outcomes was assessed by Cox regression analyses. RESULTS In all, 1303 (97.5%) patients were male, and 34 (2.5%) were female, with a mean ± SD age of 60.4 ± 10 years. The 10-year OS and DFS rates were 72.9% and 69.9%, respectively. The tumor area cutoff values that best discriminated OS and DFS rates were both 1.80 cm2. Patients with glottic carcinoma with a larger tumor area had inferior OS and DFS rates. Based on the results of multivariate analyses, tumor area was an independent prognostic factor for rates of OS (hazard ratio, 1.87; 95% CI, 1.37-2.56; P < .001) and DFS (hazard ratio, 1.79; 95% CI, 1.34-2.38; P < .001) in patients with glottic carcinoma. CONCLUSIONS The results of this study indicate that patients with glottic carcinoma with a tumor area >1.8 cm2 have inferior survival outcomes, and this factor independently predicts survival outcomes in these patients.

Abstract
Background Long noncoding RNA (lncRNA) LINC00152 (CYTOR) has been reported to be upregulated and to serve as a diagnostic biomarker in multiple types of cancers, including laryngeal squamous cell cancer (LSCC). However, the functional role and molecular mechanisms of LINC00152 in LSCC progression need to be further investigated. Methods LINC00152 levels in LSCC and adjacent normal tissues were measured by quantitative real-time polymerase chain reaction (qRT-PCR). Gene knockdown of LINC00152 was achieved in LSCC cells by use of small interfering RNA (siRNA). Cell proliferation, apoptosis, migration and invasion were examined by a series of methods. The micoRNA (miRNA) interaction with LINC00152 was screened by starBase v2.0 and confirmed by luciferase reporter activity. Results LINC00152 levels in LSCC tissues were significantly higher than those in adjacent normal tissue, and patients with lymph node metastasis or an advanced clinical stage displayed higher LINC00152 expression. Moreover, siRNA-mediated LINC00152 knockdown significantly inhibited the proliferation, migration and invasion of LSCC cells and induced apoptosis in those cells. Mechanistically, LINC00152 functioned as a competing endogenous RNA (ceRNA) sponging miR-613. The inhibitory effect of LINC00152 knockdown on malignant behavior was abrogated by inhibiting miR-613. Conclusion LINC00152 exerts an oncogenic effect on the tumorigenesis of LSCC by sponging miR-613 and may serve as a potential target for treating LSCC.

Abstract
In this article, we aimed to discuss the role of total laryngectomy (TL) in the management of patients with larynx cancer (LC) in the era of organ preservation. Before the 1990s, TL followed by radiotherapy (RT) was the standard treatment for patients with locally advanced LC. Over the last 30 years, various types of larynx preservation (LP) programs associating induction or concurrent chemotherapy (CT) with RT have been developed, with the aim of treating locally advanced LC patients while preserving the larynx and its functions. Overall, more than two-thirds of patients included in a LP program will not require total laryngectomy (TL) and will preserve a functional larynx. However, despite these advances, the larynx is the only tumor site in the upper aero-digestive tract for which prognosis has not improved during recent decades. Indeed, none of these LP protocols have shown any survival advantage compared to primary radical surgery, and it appears that certain LC patients do not benefit from an LP program. This is the case for patients with T4a LC (extra-laryngeal tumor extension through the thyroid cartilage) or with poor pretreatment laryngeal function and for whom primary TL is still the preferred therapeutic option. Moreover, TL is the standard salvage therapy for patients with recurrent tumor after an LP protocol.

Abstract
Prostate cancer (PCa) is one of the most common types of cancer in men. In several recent studies, chromosomal deletions in the q arm of chromosome 2, where ING5 resides within, have been identified in various cancer types including PCa. In this study, we investigate the role of ING5 as a tumor suppressor in PCa. We examined the expression level of ING5 in tissue samples and cell lines using quantitative real-time polymerase chain reaction and western blot analysis. We tested the in vitro tumor suppressor potential of ING5 in PC3 and LNCaP cells stably overexpressing it using cell viability, colony formation, migration, invasion, and apoptosis assays. We then investigated the effects of ING5 on the Akt and p53 signaling using western blot analysis. We show that ING5 is significantly downregulated in PCa tumor tissue samples and cell lines compared with the corresponding controls. In vitro assays demonstrate that ING5 effectively suppresses proliferative, clonogenic, migratory, and invasive potential and induce apoptosis in PCa cells. ING5 may potentially exert its anti-tumor potential by inhibiting AKT and inducing p53 signaling pathways. Our findings demonstrate that ING5 possesses tumor suppressor roles in vitro, pointing its importance during the prostatic carcinogenesis processes.

Abstract
The initiation and development of several types of cancer have been linked to long non‑coding RNA (lncRNA) X inactive‑specific transcript (XIST). Yet, the pattern of expression, function, as well as the molecular mechanism underlying XIST in laryngeal squamous cell carcinoma (LSCC) lack characterization. Therefore, the present study aimed to determine the function and putative mechanism of XIST in the development of LSCC. It was revealed that the level of XIST was significantly higher in LSCC tissues that were associated with advanced Tumor‑Node‑Metastasis (TNM) stage and the presence of lymph node metastasis. Furthermore, the ability of human LSCC TU212 cells to proliferate, form colonies, migrate and invade was significantly suppressed, while cell apoptosis was significantly increased following knockdown of XIST. Further investigation revealed that XIST knockdown increased the expression of microRNA‑144 (miR‑144) by acting as an endogenous sponge of miR‑144. Inhibition of miR‑144 caused a partial reversal of the inhibitory effects mediated following depletion of XIST in LSCC cells. Moreover, an miR‑144 target called insulin receptor substrate 1 (IRS1) was significantly decreased by XIST depletion in LSCC cells. IRS1 expression was positively correlated with XIST expression in LSCC tissues. In addition, knockdown of XIST impaired tumor growth in vivo by regulating the miR‑144/IRS1 axis. The present study demonstrated that the progression of LSCC is promoted by XIST sponging miR‑144 to regulate IRS1 expression, suggesting that XIST can serve as a putative target in the therapy of LSCC.

Abstract
Laryngeal cancer is one of the most malignant cancers among the head and neck malignant tumors. Abnormal expression of microRNAs (miRNAs) contributes to cancer development through regulating proliferation and apoptosis of cancer cells. In this study, we aim to explore the roles of microRNA-141 (miR-141), Homeobox C6 (HOXC6) and TGF-β signaling pathway in epithelial-mesenchymal transition (EMT) and lymph node metastasis in laryngeal cancer. Initially, we identified differentially expressed genes in laryngeal cancer, among which HOXC6 was identified. Then the target miRNA of HOXC6 was predicted and verified. Next, expression of miR-141, HOXC6, TGF-β1, Smad3, Vimentin and Snail in cancer tissues was detected. Then, AMC-HN-8 cells were transfected with miR-141 mimic, miR-141 inhibitor and HOXC6-siRNA to investigate specific role of miR-141, HOXC6 and TGF-β signaling pathway in laryngeal cancer in vivo and in vitro. Our results showed that HOXC6 was a target gene of miR-141, which was downregulated in laryngeal cancer. Besides, overexpression of miR-141 could downregulate HOXC6 and inhibit the TGF-β signaling pathway. Upregulation of miR-141 or silencing of HOXC6 can repress EMT, viability, migration and invasion abilities of laryngeal cancer cells. In addition, upregulation of miR-141 inhibited the tumor growth and lymph node metastasis in vivo. In summary, our findings demonstrated that upregulated miR-141 decreased HOXC6 expression, and inhibited the TGF-β signaling pathway, EMT and lymph node metastasis in laryngeal cancer, which is of clinical significance in the treatment of laryngeal cancer.

Abstract
Abstract
Background and objectives: Laryngectomy with extensive extirpational neck dissection is still the treatment of choice for patients with advanced laryngeal cancer. During the initial part of laryngectomy – tracheostomy, there is a significant upper airway obstruction, caused by the cancer process itself and worsened by surgical pressure and manipulation during creation of tracheostomy. This study aims to make comparative assessment of the patient’s hemodynamic parameters, operated using three of the most popular approaches during tracheostomy: local anesthesia with preserved spontaneous ventilation; general anesthesia with ventilation by endotracheal intubation and general anesthesia with ventilation by laryngeal mask airway.
Methods: A prospective cohort study was conducted in a tertiary referral center. Sixty patients with advanced laryngeal cancer appointed for total laryngectomy, were enrolled in the study. They were randomly assigned into three groups, according to the ventilation method used during the tracheostomy.
Results: Patients who underwent tracheostomy under local anesthesia displayed statistically the highest levels of SAP, DAP, MAP and heart rate intraoperatively. The group of patients who underwent tracheostomy with endotracheal intubation, also displayed significantly higher levels of hemodynamic parameters during the procedure compared with the group with laryngeal mask airway ventilation, despite the fact that both groups were under general anesthesia.
Conclusions: To our knowledge, this is the first study to demonstrate that laryngeal mask ventilation during tracheostomy improves intraoperative hemodynamic stability in patients undergoing total laryngectomy compared to endotracheal intubation.

Abstract
BACKGROUND Long non-coding RNAs (lncRNAs) can function as competing endogenous RNAs (ceRNAs) to interact with miRNAs to regulate target genes and promote cancer initiation and progression. The expression of lncRNAs and miRNAs can be epigenetically regulated. The goal of this study was to construct an lncRNA-miRNA-mRNA ceRNA network in laryngeal squamous cell carcinoma (LSCC) and reveal their methylation patterns, which was not investigated previously. METHODS Microarray datasets available from the Gene Expression Omnibus database were used to identify differentially expressed lncRNAs (DELs), miRNAs (DEMs), and genes (DEGs) between LSCC and controls, which were then overlapped with differentially methylated regions (DMRs). The ceRNA network was established by screening the interaction relationships between miRNAs and lncRNAs/mRNAs by corresponding databases. TCGA database was used to identify prognostic biomarkers. RESULTS Five DELs (downregulated: TMEM51-AS1, SND1-IT1; upregulated: HCP5, RUSC1-AS1, LINC00324) and no DEMs were overlapped with the DMRs, but only a negative relationship occurred in the expression and methylation level of TMEM51-AS1. Five DELs could interact with 11 DEMs to regulate 242 DEGs, which was used to construct the ceRNA network, including TMEM51-AS1-miR-106b-SNX21/ TRAPPC10, LINC00324/RUSC1-AS1-miR-16-SPRY4/MICAL2/ SLC39A14, RUSC1-AS1-miR-10-SCG5 and RUSC1-AS1-miR-7-ZFP1 ceRNAs axes. Univariate Cox regression analysis showed RUSC1-AS1 and SNX21 were associated with overall survival (OS); LINC00324, miR-7 and ZFP1 correlated with recurrence-free survival (RFS); miR-16, miR-10, SCG5, SPRY4, MICAL2 and SLC39A14 were both OS and RFS-related. Furthermore, TRAPPC10 and SLC39A14 were identified as independent OS prognostic factors by multivariate Cox regression analysis. CONCLUSION DNA methylation-mediated TMEM51-AS1 and non-methylation-mediated RUSC1-AS1 may function as ceRNAs for induction of LSCC. They and their ceRNA axis genes (particularly TMEM51-AS1-miR-106b-TRAPPC10; RUSC1-AS1-miR-16-SLC39A14) may be potentially important prognostic biomarkers for LSCC.

Abstract
Objectives. The purpose of this study was to investigate serum pituitary tumor transforming gene (PTTG1) expression in laryngeal carcinoma and its relationship with the clinical pathological characteristics and prognosis. Methods. Expression of serum PTTG1 was measured by enzyme-linked immunosorbent assay in 110 patients with laryngeal carcinoma and 60 patients with vocal cord polyps. Expression of the serum PTTG1 levels relationship with the clinicopathological characteristics and prognosis were analyzed. Results. In laryngeal carcinoma patients’ serum, the PTTG1 median concentration was 141.43 pg/mL (interquartile range [IQR], 111.387 to 160.837 pg/mL), significantly higher than that of the vocal cord polyp group of 94.01 pg/mL (IQR, 81.26 to 108.59 pg/mL), and the difference was statistically significant (z=–6.715, P<0.001). PTTG1 expression with lymph node metastasis, clinical stage, and patients with laryngeal carcinoma was significantly correlated with the tumor differentiation degree (P<0.05). The total survival rate of the PTTG1 high expression group was significantly lower than the low expression group, and the difference of total survival time of the two groups was statistically significant (P<0.001). Conclusion. The PTTG1 expression level can be used as an index for evaluating prognosis of laryngeal cancer. High PTTG1 expression is one of the factors of poor prognosis of laryngeal carcinoma patients.

Abstract
PURPOSE to describe the clinical and sociodemographic profile and analyze the voice rehabilitation outcomes of patients with laryngeal cancer. METHODS cross-sectional study with 204 individuals with laryngeal cancer treated between 1989 and 2015. The variables describing the patients' profile were presented in absolute values (n) and percentage (%). The association between the speech-language therapy outcome and the sociodemographic and clinical characterization variables was verified by means of uni- and multivariate techniques. RESULTS 95.1% of the patients are male; 53.43% are aged 60 or more; 77.37% have elementary education; 44.12% are in the service industry; 81.63% smoke and consume alcohol; 30.4% are stage T3. Absence of nodules was found in 72.00%, and of metastasis, in 85.6% of patients. The most frequent therapeutic procedure was complete or partial laryngectomy (69.61%). There was an association among education, disease stage, habits, and therapeutic outcome with speech-language therapy (p<0.001). CONCLUSION Several causes can affect the prognosis of vocal rehabilitation in patients with laryngeal cancer. Optimization and diversification of new therapeutic procedures are challenges for these patients' speech-language rehabilitation.

Abstract
SUMMARY – Helicobacter (H.) pylori is the cause of one of the most common chronic bacterial infections in humans. Risk factors for the development of laryngeal cancer are cigarette smoke, alcohol, and human papillomavirus. Several papers report on H. pylori isolated in tooth plaque, saliva, middle ear and sinuses. Many articles describe the presence of H. pylori in laryngeal cancer cases, however, without noting the possible source of infection, i.e. stomach or oral cavity. The aim of this study was to determine which patients and to what extent simultaneously developed H. pylori colonization in the stomach and the larynx. Prospective examinations were performed in 51 patients with laryngeal squamous cell carcinoma. The study group included patients with laryngeal squamous cell carcinoma histopathologically confirmed by two independent pathologists. The patients underwent fiber esophagogastroduodenoscopy with tumor tissue biopsy. Laryngeal and gastric biopsies were examined by histologic staining technique for histopathologic detection of H. pylori and with DNA analyses using the standardized fluorescent ABI Helicobacter plus-minus PCR assay. Laryngeal carcinoma patients showed positive H. pylori test results simultaneously in the laryngeal and stomach areas, implying H. pylori transmission from the stomach to the laryngeal area. In addition, H. pylori positive test results along with negative H. pylori results in the stomach region were also recorded, suggesting a possible bacteria migration from the oral cavity. In conclusion, H. pylori was found in the area of laryngeal carcinoma, and its migration appeared likely to occur both upwards (from the stomach to the mouth) and downwards (from the oral cavity to the stomach).

Abstract
MicroRNAs (miRNAs or miRs) have been identified as an important regulator in carcinogenesis and other pathological processes. However, the molecular mechanism underlying the function of miRNAs in the progression and development of laryngeal squamous cell carcinoma (LSCC) remains to be fully elucidated. In the present study, the miRNA expression pattern in LSCC tissues was profiled using miRNA microarray analysis. It was found that a large set of miRNAs are aberrantly expressed in LSCC tissues and that miR‑143‑3p was the most markedly downregulated compared with normal tissues. The low expression of miR‑143‑3p was associated with poor prognosis in LSCC. The overexpression of miR‑143‑3p repressed cellular proliferation and induced apoptosis in vitro, and inhibited tumor growth in vivo. The upregulation of miR‑143‑3p suppressed cell migration and invasion through inhibiting the epithelial‑mesenchymal transition cascade. In addition, it was verified that the oncogene k‑Ras is a target of miR‑143‑3p in LSCC cells, and the suppressive effects of miR‑143‑3p on LSCC cells were abrogated by the overexpression of k‑Ras. It was also revealed that miR‑143‑3p may inhibit cell growth and metastasis through targeting the k‑Ras/Raf/mitogen‑activated protein kinase kinase (MEK)/extracellular signal‑regulated kinase (ERK) signaling pathway. Taken together, the data indicated that the miR‑143‑3p/k‑Ras/Raf/MEK/ERK axis serves a key regulator in the development and progression of LSCC, suggesting that miR‑143‑3p may be a potential prognostic biomarker and therapeutic target in the treatment of LSCC.

Abstract
PURPOSE To identify potential molecular markers for induction chemotherapy of Laryngeal squamous cell carcinoma (LSCC). METHODS Differently expressed genes between chemo-sensitive group (seven cases) and chemo-insensitive (five cases) group after induction chemotherapy by TPF were identified by microarrays. Bayes network and Random forest analyses were employed to identify core genes for induction chemotherapy. The diagnostic value of these core genes was also evaluated by ROC analysis. RESULTS Six genes (SPP1, FOLR3, KYNU, LOC653219, ADH7 and XAGE1A) are highly expressed, while seven gene (CADM1, NDUFA4L2, CCND2, RARRES3, ERAP2, LYD6 and CNTNAP2) present significantly low expression. Among these genes, genes CADM1, FOLR3, KYNU, and CNTNAP2 are core candidates for LSCC chemo-sensitivity. And that the low expression of CADM1 may result in chemo-sensitivity, which leads to high expression of gene FOLR3 and KYNU, and low expression of gene CNTNAP2. Besides, ROC analysis shows that these four genes exhibit effective diagnostic value for induction chemo-sensitivity. CONCLUSIONS CADM1 may be a potential molecular marker for LSCC induction chemotherapy, while CADM1, FOLR3, KYNU, and CNTNAP2 may provide essential guidance for LSCC diagnosis and follow-up treatment strategies.

Abstract
BACKGROUND Laryngeal cancer is a frequent cause of cancer-associated mortality worldwide with an overall poor prognosis along with high mortality rates. Therefore, comprehensive investigation of underlying molecular mechanisms of laryngeal carcinogenesis remains an important problem. METHODS In this study, proliferative and apoptotic features of Hep-2 cells overexpressing microRNA-33a (miR-33a) were evaluated and in silico analysis along with literature search was used to find putative targets of miR-33a. The potential of PIM1 (pim-1 oncogene) as a direct target of miR-33a was tested using quantitative real-time polymerase chain reaction, Western blot, and luciferase assay. RESULTS Induced miR-33a expression significantly inhibited proliferation through inducing apoptosis of Hep-2 cells. Further in vitro tests showed downregulation of PIM1 in messenger ribonucleic acid (mRNA) and protein level upon miR-33a overexpression and confirmed PIM1 as a direct target of miR-33a. CONCLUSIONS Mir-33a was demonstrated to act as a tumor suppressor in larnygeal cancer via directly targeting the 3' untranslated region of PIM1.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is a highly aggressive malignant cancer. The regulation of LSCC progression by long non-coding RNA (lncRNA) was not well understood. In this study, we reported that the lncRNA H19 was upregulated in LSCC. The expression levels of H19 were inversely correlated with the survival rate of LSCC patients. Knockdown of H19 expression inhibited LSCC cell migration, invasion and proliferation. We identified microRNA miR-148a-3p as an inhibitory target for H19. Overexpression of miR-148a-3p reduced LSCC migration, invasion and proliferation cell, while inhibition of miR-148a-3p did the opposite. The inhibition of LSCC progression induced by H19 knockdown required the activity of miR-148a-3p. We also identified DNA methyltransferase enzyme DNMT1 as a target of miR-148a-3p. Cellular DNA methylation levels were inhibited by both miR-148a-3p overexpression and H19 knockdown. In summary, our study demonstrated that the lncRNA H19 promoted LSCC progression via miR-148a-3p and DNMT1.

Abstract
The present study was undertaken to explore the association between the expression of hepatocyte growth factor receptor (c-Met) and epidermal growth factor receptor (EGFR) with clinicopathological factors and survival status, to obtain prognostic biomarkers in patients with glottis laryngeal squamous cell carcinoma (GLSCC). The expression status of c-Met and EGFR protein was analyzed in 71 archival laryngeal cancer samples by immunohistochemistry. Statistical methods, including univariate and multivariate Cox regression analysis, were used to determine risk factors of progression. In addition, survival analysis was performed by the Kaplan-Meier method. The present study detected positive expression of c-Met and EGFR in 69.0 and 91.5% of GLSCC samples, respectively. The median disease-free survival (DFS) and overall survival (OS) times of all patients were 42.4 and 81.8 months, respectively, and the 2-year DFS and OS rates were 60.1 and 84.91%, respectively. Univariate Cox regression analysis revealed that patients with high expression of EGFR or c-Met had a predisposition for tumor recurrence. The expression of c-Met expression was significantly associated with that of EGFR (P=0.001). High expression of c-Met or EGFR was associated with shorter DFS and OS times. Findings of the multivariate Cox regression analysis indicated that c-Met-expression may be used as an independent predictor of DFS and OS (P=0.002 and P=0.008, respectively). However, EGFR expression was not an independent predictor for DFS and OS (P=0.352 and P=0.24, respectively). The high expression of c-Met and EGFR was associated with poor survival and are important predictors for prognosis of patients with GLSCC.

Abstract
Objective To evaluate the radiosensitivity effect of CpG oligodeoxyribonucleotide (ODN)
7909 on human epidermoid cancer strain-2 (Hep-2) cells in
vitro and discuss the potential for improved radiotherapy
treatment in patients with laryngeal squamous cell carcinoma. Methods Toll-like receptor (TLR) 9 expression was assessed in Hep-2
cells using Western blots and reverse transcription polymerase chain
reaction. Cell Counting Kit-8 was used to detect Hep-2 cell viability at 24
and 48 h following treatment with different CpG ODN7909 concentrations.
Cellular colonization was evaluated using microscopy. Cell cycle
distribution and apoptosis rate was determined with flow cytometry.
Interleukin (IL)-12 and tumour necrosis factor (TNF)-α concentrations were
detected by enzyme-linked immunosorbent assay. Results Hep-2 cells were found to express TLR9, and CpG ODN7909
treatment suppressed Hep-2 cell viability in a dose- and time-dependent
manner. Cell survival curve analyses revealed a sensitivity enhancement
ratio of the mean death dose of 1.225 for CpG ODN7909 plus irradiation
versus irradiation alone. Furthermore, the population of Gap 2/mitotic-phase
cells, apoptosis rate and secreted IL-12 and TNF-α levels were significantly
increased in Hep-2 cells treated with CpG ODN7909 plus irradiation versus IR
alone. Conclusion CpG ODN7909 enhanced the radiosensitivity of Hep-2 cells in
vitro.

Abstract
Enhancer of zeste homolog 2 (EZH2) is a highly conserved histone methyltransferase, which is overexpressed in different types of cancers such as breast and prostate cancer. It is reported that EZH2 can directly down-regulate RUNX3 by increasing histone H3 methylation. However, the role of EZH2 in the development and progression of laryngeal carcinoma has not yet been investigated, and the relationship between EZH2 and RUNX3 in laryngeal carcinoma is rarely reported. The current study aims to determine the role of EZH2 in the progression of laryngeal carcinoma, and investigate the interaction between EZH2 and the tumor suppressor RUNX3. Our study found that EZH2 is overexpressed in laryngeal carcinoma patients, and silencing EZH2 by EZH2 siRNA significantly inhibited the proliferation of laryngeal carcinoma cells. Besides, we also found that RUNX3 is repressed in laryngeal carcinoma patients. Moreover, RUNX3 as a downstream target protein of EZH2 is up-regulated by EZH2 siRNA accompanied by a decrease in the trimethylation modification pattern of H3K27. RUNX3 siRNA inhibits the decreased proliferation induced by EZH2 siRNA. Furthermore, β-catenin protein expression is down-regulated by EZH2 siRNA and up-regulated by RUNX3 siRNA, and RUNX3 siRNA inhibits the down-regulation effect of EZH2 siRNA on β-catenin protein expression. Additionally, the Wnt/β-catenin activator BIO reverses the inhibitory effect of EZH2 siRNA on Hep-2 cell proliferation. Taken together, our results suggest that EZH2 regulates cell proliferation potentially by targeting RUNX3 through the Wnt/β-catenin signaling pathway in laryngeal carcinoma.

Abstract
Long non-coding RNAs have been proved to be closely associated with different cancers. This study was designed to elucidate the function and mechanisms of colon cancer-associated transcript-1 in the progression of human laryngeal squamous cell cancer. Expressions of colon cancer-associated transcript-1, microRNA-218, and zinc finger protein, X-linked messenger RNA were measured using quantitative real-time polymerase chain reaction, and the expression level of zinc finger protein, X-linked protein was detected using western blot. Proliferation and invasion of laryngeal squamous cell cancer cell lines were detected by Cell Counting Kit-8 assay and Transwell invasion assay, respectively. Luciferase assay was used to confirm whether microRNA-218 is a target of colon cancer-associated transcript-1 and whether microRNA-218 directly binds to 3'-untranslated region of zinc finger protein, X-linked messenger RNA. Effect of colon cancer-associated transcript-1 on tumor growth was observed through xenograft mice models in vivo. The results showed that expressions of colon cancer-associated transcript-1 and zinc finger protein, X-linked were significantly higher while microRNA-218 expression was significantly lower in the laryngeal squamous cell cancer tissues than those in the adjacent normal tissues. MicroRNA-218 overexpression or zinc finger protein, X-linked silencing significantly suppressed proliferation and invasion of laryngeal squamous cell cancer cells. Moreover, knockdown of colon cancer-associated transcript-1 significantly inhibited proliferation and invasion of laryngeal squamous cell cancer cells, which were reversed by microRNA-218 downregulation or zinc finger protein, X-linked upregulation. Finally, colon cancer-associated transcript-1 silencing inhibited xenograft tumor growth of laryngeal squamous cell cancer in vivo. In conclusion, colon cancer-associated transcript-1 knockdown inhibits proliferation and invasion of laryngeal squamous cell cancer cells through enhancing zinc finger protein, X-linked by sponging microRNA-218, elucidating a novel colon cancer-associated transcript-1-microRNA-218-zinc finger protein, X-linked regulatory axis in laryngeal squamous cell cancer and providing a promising therapeutic target for laryngeal squamous cell cancer patients.

Gong H, Shi Y, Xiao X, Cao P, Wu C, Tao L, Hou D, Wang Y, Zhou L. Alterations of microbiota structure in the larynx relevant to laryngeal carcinoma. Sci Rep 2017; 7:5507. [PMID: 28710395 PMCID: PMC5511217 DOI: 10.1038/s41598-017-05576-7] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2017] [Accepted: 05/31/2017] [Indexed: 02/07/2023] Open
Abstract
The microbial communities that inhabit the laryngeal mucosa build stable microenvironments and have the potential to influence the health of the human throat. However, the associations between the microbiota structure and laryngeal carcinoma remain uncertain. Here, we explored this question by comparing the laryngeal microbiota structure in laryngeal cancer patients with that in control subjects with vocal cord polyps through high-throughput pyrosequencing. Overall, the genera Streptococcus, Fusobacterium, and Prevotella were prevalent bacterial populations in the laryngeal niche. Tumor tissue samples and normal tissues adjacent to the tumor sites (NATs) were collected from 31 laryngeal cancer patients, and the bacterial communities in laryngeal cancer patients were compared with control samples from 32 subjects. A comparison of the laryngeal communities in the tumor tissues and the NATs showed higher α-diversity in cancer patients than in control subjects, and the relative abundances of seven bacterial genera differed among the three groups of samples. Furthermore, the relative abundances of ten bacterial genera in laryngeal cancer patients differed substantially from those in control subjects. These findings indicate that the laryngeal microbiota profiles are altered in laryngeal cancer patients, suggesting that a disturbance of the microbiota structure might be relevant to laryngeal cancer.

Abstract
INTRODUCTION In human cancers, podoplanin expression and its correlation with tumour invasive potential raise its possible role as a diagnostic and prognostic marker for cancer. AIM To investigate the immunohistochemical expression of podoplanin in laryngeal Squamous Cell Carcinoma (SCC) and dysplasia. MATERIALS AND METHODS This study included a total of 60 archived, formalin fixed, paraffin embedded tissue blocks of 40 cases of laryngeal SCC and 20 cases of dysplastic lesions. The samples were immunohistochemically analysed for podoplanin expression. RESULTS Podoplanin expression was significantly higher in laryngeal SCC (90%) than laryngeal dysplastic lesions (55%) (p-value=0.002). The expression of podoplanin was significantly increased with the higher grades of dysplasia (p-value=0.016). A significant positive correlation was detected between podoplanin expression in laryngeal SCC and depth of tumour invasion (p-value=0.035), and stage (p-value=0.026). CONCLUSION The high expression of podoplanin in laryngeal SCC and its significant correlation with poor prognostic parameters recommends podoplanin as a prognostic marker in laryngeal SCC. In addition, increased podoplanin expression with higher grades of dysplasia, supports its role in malignant transformation and allows us to recommend its evaluation in premalignant lesions.

Abstract
Background: Laryngeal squamous cell carcinoma ranks second among head and neck squamous-cell carcinomas. Cancer stem cells can support cancer growth and malignant behavior. Therefore, cancer stem cells isolated from laryngeal squamous cell carcinoma tissue could be used to investigate the initiation, progression, and treatment strategies of this cancer. Methods: We isolated CD133-CD44-, CD133-CD44+, CD133+CD44- and CD133+CD44+ cell populations from laryngeal squamous-cell carcinoma cell lines Hep2 and TU-177 by magnetic-activated cell sorting. Sphere formation, cell proliferation, migration, invasion, colony formation, resistance to radio- and chemotherapy, and in vivo tumorigenicity of these populations were evaluated. Moreover, we investigated the expression of the stem-cell markers (sex determining region Y)-box 2 (SOX2) and octamer-binding transcription factor 4 (OCT4) in CD133-CD44-, CD133-CD44+, CD133+CD44-, CD133+CD44+ cell populations and parental Hep2 and TU-177 cells. Results: As compared with CD133-CD44-, CD133-CD44+, CD133+CD44- populations and parental cells, CD133+CD44+ cells showed higher cell viability, migration and invasive capability and colony formation ability as well as stronger resistance to cisplatin and irradiation. Moreover, levels of SOX2 and OCT4 and tumorigenicity in nude mice were greater in CD133+CD44+ Hep2 and TU-177 cells than other cell populations and parental cells. Conclusion: The CD133+CD44+ population of laryngeal squamous-cell carcinoma Hep2 and TU-177 cells have stem cell properties and showed more malignant features than CD133+CD44- and CD133-CD44+ cell populations. CD133+CD44+ cancer stem cells may be a promising target for developing anticancer drugs and treatment strategies for laryngeal squamous cell carcinoma.

Abstract
Background Emerging evidences proposed that microRNAs are associated with regulation of distinct physio-pathological processes including development of normal stem cells and carcinogenesis. In this study we aimed to investigate microRNA profile of cancer stem-like cells (CSLCs) isolated form freshly resected larynx cancer (LCa) tissue samples. Methods CD133 positive (CD133+) stem-like cells were isolated from freshly resected LCa tumor specimens. MicroRNA profile of 12 pair of CD133+ and CD133− cells was determined using microRNA microarray and differential expressions of selvected microRNAs were validated by quantitative real time PCR (qRT-PCR). Results MicroRNA profiling of CD133+ and CD133− LCa samples with microarray revealed that miR-26b, miR-203, miR-200c, and miR-363-3p were significantly downregulated and miR-1825 was upregulated in CD133+ larynx CSLCs. qRT-PCR analysis in a total of 25 CD133+/CD133− sample pairs confirmed the altered expressions of these five microRNAs. Expressions of miR-26b, miR-200c, and miR-203 were significantly correlated with miR-363-3p, miR-203, and miR-363-3p expressions, respectively. Furthermore, in silico analysis revealed that these microRNAs target both cancer and stem-cell associated signaling pathways. Conclusions Our results showed that certain microRNAs in CD133+ cells could be used as cancer stem cell markers. Based on these results, we propose that this panel of microRNAs might carry crucial roles in LCa pathogenesis through regulating stem cell properties of tumor cells.

Abstract
BACKGROUND The primary goal of treatment in advanced laryngeal cancer is to achieve optimal oncologic outcomes while preserving function and quality of life. Combination of chemotherapy and radiation has been popularized as an alternative to surgery for patients facing total laryngectomy. However, survival analyses from large, population-based databases have not duplicated results reported from randomized trials. METHODS A comprehensive literature review was undertaken to try to better understand the reasons why results differ among randomized trials and population cohort studies. RESULTS A variety of reasons are discussed, including differences in patient staging, selection bias, complexity bias, inconsistent terminology, patient compliance and treatment expertise. CONCLUSIONS Personalized treatment considering all factors is critical for optimal outcomes. In general, evidence supports total laryngectomy for patients with T4 cancers. Definitive chemoradiotherapy strategies are acceptable alternatives for T3 cancers, provided that all resources for the administration of the treatment, follow-up and surgical salvage are available.

Abstract
Circular RNAs (circRNAs), a class of endogenous RNAs, are characterized by covalently closed continuous loop without 5' to 3' polarity and polyadenylated tail. Recent studies indicated that circRNAs might play an important role in cancer. However, the function of circRNA in laryngeal squamous cell cancer tissues (LSCC) is still unknown. In this study, we investigated the expression of circRNAs in 4 paired LSCC tissues and adjacent non-tumor tissues by microarray analysis. Results showed significant upregulation (n = 302) of or downregulation (n = 396) of 698 circRNAs in LSCC tissues. We further detected hsa_circRNA_100855 as the most upregulated circRNA and hsa_circRNA_104912 as the most downregulated circRNA using qRT-PCR methods. Results showed that hsa_circRNA_100855 level was significantly higher in LSCC than in the corresponding adjacent non-neoplastic tissues. Patients with T3-4 stage, neck nodal metastasis or advanced clinical stage had higher hsa_circRNA_100855 expression. The hsa_circRNA_104912 level was significantly lower in LSCC than in corresponding adjacent non-neoplastic tissues. Patients with T3-4 stage, neck nodal metastasis, poor differentiation or advanced clinical stage had a lower hsa_circRNA_104912 expression. Overall, our data suggest that circRNAs play an important role in the tumorigenesis of LSCC and may serve as novel and stable biomarkers for the diagnosis and progress of LSCC.
