Xu X, Yang X, Tang J, Wu X, He X. Identification of Regulatory RNA-Binding Proteins Associated with Immune Infiltration in Laryngeal Squamous Cell Carcinoma. JOURNAL OF IMMUNOLOGY (BALTIMORE, MD. : 1950) 2024; 213:394-402. [PMID: 38912837 DOI: 10.4049/jimmunol.2300498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 03/27/2024] [Indexed: 06/25/2024]
Abstract
We analyzed bulk RNA sequencing and single-cell RNA sequencing (scRNA-seq) data to identify alternative splicing (AS) events and regulatory RNA-binding proteins (RBPs) associated with immune infiltration in human laryngeal squamous cell carcinoma (LSCC). Whole-transcriptome sequencing data of 20 human laryngeal cancer and paracancerous tissues were downloaded from the Gene Expression Omnibus public database, using newly published splicing-site usage variation analysis software to obtain highly conserved regulated AS (RAS) events, and scientific reverse convolution algorithm analysis was used to identify significantly different immune cells and perform a correlation analysis between the two. The software package edgeR was used to identify differentially expressed RBPs and the immune infiltration-related LSCC-RAS they may regulate. Finally, we present the expression profiles and survival curves of 117 human laryngeal cancer samples from The Cancer Genome Atlas dataset for the identified RBPs and LSCC-RAS. We also downloaded the gene set enrichment 150321 scRNA-seq data for two human LSCC tissue samples. The RBP expression pattern and the expression of prophase RBP genes were analyzed in different LSCC cell populations. RNA-binding motif protein 47 (RBM47) and filamin A, as well as the RBP-RAS events that were screened in both the fibulin 2 and fibronectin 1 genes, were all significantly associated with the prognosis, and the RBM47 gene was upregulated in myeloid cells. Because the prognosis was significantly associated with two RBP regulators and two LSCC-RAS events, they may be critical regulators of immune cell survival during laryngeal cancer progression, and RBM47 may regulate macrophage-associated AS and affect immunity.

Abstract
Rhabdomyosarcoma (RMS) is commonly reported in children and very rarely in adults. Laryngeal RMS is a rare but extremely aggressive malignancy with a high mortality rate. Surgery followed by postoperative radiotherapy is the preferred treatment. The use of chemotherapy is debatable. This report highlights a case of rare pleomorphic rhabdomyosarcoma of glottis in a 67-year-old male who presented with hoarseness and a description of its management.

Abstract
PURPOSE This study aims to evaluate how various demographic factors impact the stage at diagnosis and, therefore, prognosis of laryngeal cancer. MATERIALS AND METHODS Using the National Cancer Database, 96,409 patients were diagnosed with laryngeal squamous cell carcinoma between 2004 and 2020. Early (stage 0 or I) vs. late-stage (stage IV) cancers were compared based on demographic variables utilizing Chi-square and multivariate analysis with a significance of p < 0.05. RESULTS Female, Black, and generally older patients were more likely to have late-stage cancer than their counterparts. When compared with a community cancer program, patients treated at other facility types were more likely to be diagnosed late. Patients with private insurance, Medicare, or other government insurance were all less likely to have late-stage cancer compared to patients without insurance. Compared to patients in the lowest median household income quartile, patients in the third quartile and fourth quartile were diagnosed earlier. Patients living in an area with the lowest level of high school degree attainment were most likely to be diagnosed late. Living in a more populous area was associated with a lower chance of being diagnosed late. Increasing Charlson-Deyo Score was associated with a stronger likelihood of being diagnosed at a later stage. CONCLUSION Patients who are female, Black, uninsured, have a low household income, live in less populated and less educated areas, are treated at non-community cancer programs, and have more comorbid conditions have later stage diagnoses. This data contributes to understanding inequities in healthcare.

Abstract
PURPOSE In early glottic squamous cell carcinoma, similar results have been described in terms of disease control between transoral laser microsurgery (TLM) and radiation therapy (RT). During the past two decades, several studies compared subjective vocal outcomes of exclusive RT with those of TLM, showing a trend towards improving results for TLM over time. However, the objective differences in terms of spectro-acoustic voice parameters between exclusive RT and TLM have been less frequently investigated. The aim of this systematic review with meta-analysis was to evaluate voice quality after TLM and RT treatment for early glottic carcinoma, based on acoustic analysis parameters including jitter, shimmer, noise to harmonic ratio, fundamental frequency and maximum phonation time. MATERIAL AND METHODS A search of the English published literature was conducted on the Pubmed, Scopus and Cochrane databases following PRISMA guidelines. RESULTS A total of 441 titles were retrieved from the search. After full-text screening and application of inclusion/exclusion criteria, 12 articles were included. We found no significant differences between TLM and RT treatment in the considered acoustic analysis parameters, except for Shimmer, with more favorable values reported in the RT group. CONCLUSIONS Considering the spread of the disease and expecting an improvement in long-term survival over time, well-designed and multicentric studies involving larger populations with a long-term follow up are mandatory to better assess objective voice outcomes in terms of spectro-acoustic voice parameters.

Abstract
OBJECTIVE To explore the clinical effectiveness of reconstructing laryngeal function using thyroid cartilage fenestration and "draw-out" resection, supplemented by internal fixation with titanium microplates in early glottic carcinoma. METHODS Data from 99 patients with glottic carcinoma treated in the Second Affiliated Hospital of Fujian Medical University between January 2014 and September 2021 were retrospectively analyzed. Forty-eight patients who underwent thyroid cartilage fenestration and resection followed by internal fixation with titanium microplates for laryngeal function reconstruction were assigned to the thyroid cartilage fenestration group (TCF group), while the other 51 patients who underwent sternohyoid muscle and fascia repair for laryngeal function reconstruction were assigned to the sternohyoid muscle repair group (SMR group). Patients were followed up for 1-8 years. Data on postoperative phonatory function, respiratory function, swallowing function, and survival status were collected. RESULTS Compared to the SMR group, patients in the TCF group showed better postoperative recovery in phonatory function and verbal communication (all P<0.05). In the TCF group, patients demonstrated stable respiration and the extubation rate was 100.00%, which was significantly higher than 82.35% in the SMR group (P<0.05). Patients in both groups showed good postoperative recovery of swallowing function (P>0.05). CONCLUSION One-stage reconstruction of laryngeal function by thyroid cartilage fenestration and "draw-out" resection with adjuvant internal titanium microplate fixation in early glottic carcinoma demonstrates good postoperative recovery and good preservation of the laryngeal function.

Abstract
OBJECTIVE Accurate vocal cord leukoplakia classification is instructive for clinical diagnosis and surgical treatment. This article introduces a reliable very deep Siamese network for accurate vocal cord leukoplakia classification. STUDY DESIGN A study of a classification network based on a retrospective database. SETTING Academic university and hospital. METHODS The white light image datasets of vocal cord leukoplakia used in this article were classified into 6 classes: normal tissues, inflammatory keratosis, mild dysplasia, moderate dysplasia, severe dysplasia, and squamous cell carcinoma. The classification performance was assessed by comparing it with 6 classical deep learning models, including AlexNet, VGG Net, Google Inception, ResNet, DenseNet, and Vision Transformer. RESULTS Experiments show the superior classification performance of our proposed network compared to state-of-the-art methods. The overall accuracy is 0.9756. The values of sensitivity and specificity are very high as well. The confusion matrix provides information for the 6-class classification task and demonstrates the superiority of our proposed network. CONCLUSION Our very deep Siamese network can provide accurate classification results of vocal cord leukoplakia, which facilitates early detection, clinical diagnosis, and surgical treatment. The excellent performance obtained in white light images can reduce the cost for patients, especially those living in developing countries.

[PMID: 37974887 PMCID: PMC10645804 DOI: 10.1007/s12070-023-03934-8] [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: 05/17/2023] [Accepted: 06/01/2023] [Indexed: 11/19/2023] Open
Abstract
The literature focuses primarily on laryngeal differentiated squamous cell carcinoma (SCC), and only a limited number of studies have evaluated the outcomes of rare variants of SCC (vSCC) and non-SCC malignancies (nSCC). To our knowledge, this is the first study to compare the survival outcomes of these two groups. We retrospectively reviewed the records of 816 patients who underwent laryngeal surgery from January 2010 to November 2022. Forty-nine (6.2%) were identified as having unusual larynx malignancies and categorized in the nSCC or vSCC groups. The patients' clinicopathological features were then recorded. We compared the two groups' overall survival (OS) and recurrence-free survival (RFS) outcomes. Thirty-three (4.2%) patients had vSCC, and 16 (2%) had nSCC. Forty-two (85.7%) were male, and the mean age was 58.57 years. The median follow-up time was 69 months. The 5-year OS rate was 71.4% in the nSCC group vs. 87.9% in the vSCC group (p = .055). Only surgical margin (HR: 4.68; 95% CI:1.13-19.37, p = .033) was an independent prognostic factor for OS in the multivariable analysis. The 5-year RFS rate was 50% for the nSCC group compared to 90.9% for the vSCC group (p < .001). In the multivariable analysis, surgical margin positivity (HR: 21.0, 95% CI 3.97-98.1, p < .001), and lymphovascular invasion (HR: 0.043, 95% CI 0.005-0.357, p = .004) were independent prognostic factors for RFS. Although OS did not show a statistical difference, nSCC malignancies of the larynx demonstrated worse OS and RFS outcomes than vSCC malignancies.

Abstract
Surgical resection is recommended for advanced-stage, resectable glottic cancer. However, total laryngectomy results in the loss of vocal function and reduces patients' quality of life. At our institution, patients with cT3N0M0 stage III resectable glottic cancer who wish to preserve their larynx are treated with super-selective cisplatin infusion with concomitant radiotherapy (RADPLAT) to improve local control over systemic chemotherapy. Herein, we present 4 patients with glottic cancer who underwent biweekly intra-arterial infusion chemotherapy combined with radiation therapy 3 times. For intra-arterial infusion chemotherapy, 100 mg cis-diaminodichloroplatinum was infused into the superior thyroid artery, including the superior laryngeal artery branch. Thereafter, intensity-modulated radiation therapy was administered at doses of 70 Gy in 35 fractions for 3 patients and 66 Gy in 33 fractions for 1 patient. These patients showed complete response after chemoradiotherapy with no recurrence or metastases during the follow-up period to date (mean follow-up period: 56 months, range: 39-76 months).

The Effectiveness of White Light Endoscopy Combined With Narrow Band Imaging Technique Using Ni Classification in Detecting Early Laryngeal Carcinoma in 114 Patients: Our Clinical Experience. J Voice 2023:S0892-1997(23)00280-1.

Abstract
INTRODUCTION By displaying tumor-specific neoangiogenesis, narrow band imaging (NBI), a novel imaging approach, enhances the diagnosis of head and neck cancers and makes it more accurate OBJECTIVE: To determine the effect of NBI in combination with white light endoscopy (WLE) for diagnosis of preneoplastic or neoplastic laryngeal cancers according to Ni classification and to conclude if higher Ni classification and tumor stage are related. METHODS We enrolled 114 patients with various laryngeal cancer between December 2018 and June 2021. Patients were examined with WLE and NBI. Squamous cell carcinoma (SCC) accounted for 46 cases, benign lesions 30 cases, and nondysplastic, low-grade, and severe dysplasias for 38 cases. Based on characteristics of the intraepithelial papillary capillary loop (IPCL), endoscopic NBI results were divided into five categories (I, II, III, IV, and V). Type I-IV are regarded to be benign, while type V is considered to be cancerous. An incisional biopsy was conducted to assess histopathology, and the histopathology was compared to the NBI results. We assessed the negative predictive value (NPV), positive predictive value (PPV), specificity, and sensitivity for WLE alone and WLE combined with NBI. Analyses were conducted using SPSS software version 26. RESULTS The WLE combined with NBI showed excellent sensitivity (96%) compared to WLE (86.4%). Specificity was higher in the WLE combined with NBI (96.4%) than WLE alone (91.7%). WLE combined with NBI saw a NPV of 89% as compared with WLE with 88%. WLE and WLE in combination with NBI, recorded a PPV of 90% and 98%, respectively. CONCLUSION The accuracy of detecting laryngeal cancer increases when WLE and NBI are combined. Combined NBI with WLE remains highly sensitive to early glottis cancer. Accuracy of preoperative NBI was high. In the diagnosis of laryngeal cancer, a higher Ni classification closely correlates with the late stages of the glottis tumor.

Tang X, Tang Q, Li S, Li M, Yang T. IGF2BP2 acts as a m 6A modification regulator in laryngeal squamous cell carcinoma through facilitating CDK6 mRNA stabilization. Cell Death Discov 2023; 9:371. [PMID: 37816718 PMCID: PMC10564923 DOI: 10.1038/s41420-023-01669-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 09/22/2023] [Accepted: 09/28/2023] [Indexed: 10/12/2023] Open
Abstract
Laryngeal squamous cell carcinoma (LSCC) is one of the most commonly seen cancers in the head and neck region with increasing morbidity and mortality globally. N6-methyladenosine (m6A) modification plays a critical role in the carcinogenesis of LSCC. In this study, two datasets from online database were analyzed for differentially expressed genes (DEGs) between LSCC and normal samples. Furthermore, we carried out a series of experiments, including hematoxylin & eosin staining, immunohistochemical (IHC) staining, CCK-8, colony formation, transwell, flow cytometry, xenograft tumor model assays, actinomycin D assay, cycloheximide (CHX) assay, methylated m6A RNA immunoprecipitation (Me-RIP), RNA immunoprecipitation (RIP) assay, to verify the relevant findings in vivo and in vitro. Insulin like growth factor 2 mRNA binding protein 2 (IGF2BP2) was identified as an up-regulated m6A regulator in LSCC samples. Lower IGF2BP2 expression was linked to higher survival probability in LSCC and other head and neck squamous cell carcinoma patients. In LSCC cells, IGF2BP2 knockdown attenuated cancer cell aggressiveness, possibly through modulating cell cycle arrest. In the xenograft tumor model derived from IGF2BP2 knocked-down LSCC cells, IGF2BP2 knockdown inhibited tumor growth. IGF2BP2 up-regulated CDK6 expression through facilitating the stability of CDK6 mRNA and protein. CDK6 knockdown caused no changes in IGF2BP2 expression, but partially eliminated the promotive effects of IGF2BP2 overexpression on LSCC cells' aggressiveness. Overexpressed IGF2BP2 in LSCC serves as an oncogenic factor, promoting LSCC cell proliferation and invasion in vitro and tumor growth in a xenograft tumor model in vivo through facilitating CDK6 mRNA stabilization.

Abstract
BACKGROUND Laryngopharyngeal cancer (LPC) includes laryngeal and hypopharyngeal cancer, whose early diagnosis can significantly improve the prognosis and quality of life of patients. Pathological biopsy of suspicious cancerous tissue under the guidance of laryngoscopy is the gold standard for diagnosing LPC. However, this subjective examination largely depends on the skills and experience of laryngologists, which increases the possibility of missed diagnoses and repeated unnecessary biopsies. We aimed to develop and validate a deep convolutional neural network-based Laryngopharyngeal Artificial Intelligence Diagnostic System (LPAIDS) for real-time automatically identifying LPC in both laryngoscopy white-light imaging (WLI) and narrow-band imaging (NBI) images to improve the diagnostic accuracy of LPC by reducing diagnostic variation among on-expert laryngologists. METHODS All 31,543 laryngoscopic images from 2382 patients were categorised into training, verification, and test sets to develop, validate, and internal test LPAIDS. Another 25,063 images from five other hospitals were used as external tests. Overall, 551 videos were used to evaluate the real-time performance of the system, and 200 randomly selected videos were used to compare the diagnostic performance of the LPAIDS with that of laryngologists. Two deep-learning models using either WLI (model W) or NBI (model N) images were constructed to compare with LPAIDS. RESULTS LPAIDS had a higher diagnostic performance than models W and N, with accuracies of 0·956 and 0·949 in the internal image and video tests, respectively. The robustness and stability of LPAIDS were validated in external sets with the area under the receiver operating characteristic curve values of 0·965-0·987. In the laryngologist-machine competition, LPAIDS achieved an accuracy of 0·940, which was comparable to expert laryngologists and outperformed other laryngologists with varying qualifications. CONCLUSIONS LPAIDS provided high accuracy and stability in detecting LPC in real-time, which showed great potential for using LPAIDS to improve the diagnostic accuracy of LPC by reducing diagnostic variation among on-expert laryngologists.

Abstract
Laryngeal cancer is a very common tumor in the upper aero-digestive tract. Understanding its biological mechanisms has garnered significant interest in recent years. The development of laryngeal squamous cell carcinoma (LSCC) follows a multistep process starting from precursor lesions in the epithelium. Various risk factors have been associated with laryngeal tumors, including smoking, alcohol consumption, opium use, as well as infections with HPV and EBV viruses, among others. Cancer development involves multiple steps, and genetic alterations play a crucial role. Tumor suppressor genes can be inactivated, and proto-oncogenes may become activated through mechanisms like deletions, point mutations, promoter methylation, and gene amplification. Epigenetic modifications, driven by miRNAs, have been proven to contribute to LSCC development. Despite advances in molecular medicine, there are still aspects of laryngeal cancer that remain poorly understood, and the underlying biological mechanisms have not been fully elucidated. In this narrative review, we examined the literature to analyze and summarize the main steps of carcinogenesis and the risk factors associated with laryngeal cancer.

Abstract
BACKGROUND Laryngeal squamous cell carcinoma (LSCC) represents one of the principal tumors of the head and neck. Human papillomavirus (HPV) and Epstein-Barr virus (EBV) are considered risk factors for the development and the clinical prognosis of LSCC. High levels of p16INK4a are suggested as a surrogate marker of HPV or EBV infection in some head and neck tumors but in LSCC is still controversial. Furthermore, pRb expression may be considered an additional biomarker but it has not been clearly defined. This work aimed to compare the expression of pRb and p16INK4a as possible biomarkers in tumor tissues with and without infection by EBV or different genotypes of HPV from patients with LSCC. METHODS Tumor samples from 103 patients with LSCC were previously investigated for the presence and genotypes of HPV using the INNO-LiPA line probe assay and for the infection of EBV by qPCR. p16 INK4a and pRb expression was assessed by immunohistochemistry. RESULTS Of the 103 tumor samples, expression of p16INK4a was positive in 55 (53.4%) and of this, 32 (56.1%) were positive for HPV whereas 11 (39.3%) were EBV positive but both without a significantly difference (p > 0.05). pRb expression was positive in 78 (75.7%) and a higher frequency of this expression was observed in HPV negative samples (87.0%) (p = 0.021) and in high-risk HPV negative samples (85.2%) (p = 0.010). No difference was observed when comparing pRb expression and EBV infection status (p > 0.05). CONCLUSION Our results support the suggestion that p16INK4a is not a reliable surrogate marker for identifying HPV or EBV infection in LSCC. On the other hand, most of our samples had pRb expression, which was more frequent in tumors without HPV, suggesting that pRb could indicate HPV negativity. However, more studies with a larger number of cases are required, including controls without LSCC and evaluating other molecular markers to determine the real role of p16INK4a and pRb in LSCC.

Abstract
(1) Background: Non-squamous cell laryngeal carcinoma includes endothelial tumors, such as minor salivary gland tumors, lymphoepithelial tumors, neuroendocrine tumors, soft and hard tissue sarcomas, and malignant melanomas. (2) Methods: A state-of-the-art review using the MEDLINE/PUBMED, Google Scholar, Ovid Medline, Embase, and Scopus electronic databases was performed. (3) Conclusions: In order to optimize overall treatment outcomes, a multidisciplinary, patient-centered approach to the management of non-SCC of the larynx must be adopted universally; a national or international registry on non-SCC laryngeal cancer can be useful to improve understanding about the behavior of this kind of tumor.

Abstract
Prognosis is defined as the likely outcome or course of a disease and is the result of a complex interplay between patient and tumor factors. Unfortunately, the prognosis of patients with laryngeal cancer has not changed significantly over the past several decades. However, as our understanding of these patient and tumor factors becomes more nuanced and the resulting treatment options become more precise, there is the potential to improve the prognosis for these patients.

Abstract
The pathology of non-squamous carcinoma of the larynx is broad and there is a wide differential diagnosis. The most common presenting symptoms for laryngeal malignancies, both squamous and non-squamous, are hoarseness and dyspnea. Presentation with persistent or worsening symptoms and a submucosal lesion should raise suspicion for a non-squamous malignancy of the larynx. Accurate histology determines the most appropriate treatment and has an impact on prognosis.

Abstract
Narrow band imaging is an established non-invasive tool used for the early detection of laryngeal cancer in surveillance examinations. Most images produced from the examination are useless, such as blurred, specular reflection, and underexposed. Removing the uninformative frames is vital to improve detection accuracy and speed up computer-aided diagnosis. It often takes a lot of time for the physician to manually inspect the informative frames. This issue is commonly addressed by a classifier with task-specific categories of the uninformative frames. However, the definition of the uninformative categories is ambiguous, and tedious labeling still cannot be avoided. Here, we show that a novel unsupervised scheme is comparable to the current benchmarks on the dataset of NBI-InfFrames. We extract feature embedding using a vanilla neural network (VGG16) and introduce a new dimensionality reduction method called UMAP that distinguishes the feature embedding in the lower-dimensional space. Along with the proposed automatic cluster labeling algorithm and cost function in Bayesian optimization, the proposed method coupled with UMAP achieves state-of-the-art performance. It outperforms the baseline by 12% absolute. The overall median recall of the proposed method is currently the highest, 96%. Our results demonstrate the effectiveness of the proposed scheme and the robustness of detecting the informative frames. It also suggests the patterns embedded in the data help develop flexible algorithms that do not require manual labeling.

Abstract
Background: The aims of our article were to identify the core genes of the autophagy-related genes (ARGs) which abnormally expressed in laryngeal cancer (LC) and constructed a risk prognostic models with these genes. Methods: In this study, we identified genes with abnormally
expressed in LC, and they were mainly involved in some cancer-related gene ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes pathways (KEGG). Statistical analysis were conducted to identify the powerful independent prognostic factors associated with clinical factors and survival.
Results: A total of 35 DEGs were identified in our research. The risk prediction model was constructed with three potential prognostic genes (VEGFA, SPNS1 and CCL2) of autophagy by lasso regression analysis that can successfully predict the prognosis in LC. We applied ROC curve to evaluate
the effectiveness of the risk prognostic model, and found that AUC was 0.693 below the curve. Risk prediction model was only related to survival status (P < 0.01), and was not related to clinicopathological factors. Furthermore, the genes (VEGFA and CCL2) were considered as core
genes not only because they were the highly connected genes but also they were the composed genes of risk prognostic model. Conclusions: Taken together, ARGs were considered as important roles in the progression of LC and the prognostic model can help to identification of new targets
to guide the diagnosis and therapy.

Abstract
The immune system greatly affects the prognosis of various malignancies. Studies on differentially expressed immune-related genes (IRGs) in the immune microenvironment of laryngeal squamous cell carcinoma (LSCC) have rarely been reported. In this paper, the prognostic potentials of IRGs were explored in LSCC patients with smoking use. The RNA-seq data containing IRGs and corresponding clinical information of smoking LSCC patients was obtained from The Cancer Genome Atlas (TCGA). Differentially expressed IRGs were identified and functional enrichment analysis was used to reveal the pathway of IRGs. Then, IRGs with prognostic potentials in smoking LSCC patients were screened out by univariate Cox regression analysis. Finally, multivariate Cox regression analysis was conducted to assess the prognostic signature of 5 IRGs after adjustment of clinical factors and patients were classified into two subgroups based on different IRGs expression. The prognostic capacity of the model was verified by another independent cohort from Gene Expression Omnibus (GEO) database. Nomogram including the prognostic signature was established and shown some clinical net benefit. These findings may contribute to the development of potential therapeutic targets and biomarkers for the new-immunotherapy of LSCC patients with smoking use.

Prognostic value of a microRNA-pair signature in laryngeal squamous cell carcinoma patients. Eur Arch Otorhinolaryngol 2022; 279:4451-4460. [PMID: 35478043 DOI: 10.1007/s00405-022-07404-9] [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: 02/16/2022] [Accepted: 04/13/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE Predicting the prognosis in laryngeal squamous cell carcinoma (LSCC) patients will improve clinical decision-making. Here, we aimed to identify a qualitative signature based on the within-sample relative expression orderings (REOs) of microRNA (miRNA) pairs to predict the overall survival (OS) of LSCC patients. METHODS First, we constructed non-repeating miRNA pairs based on differentially expressed miRNAs (DEmiRNAs) between LSCC and normal tissues. Then, we applied a bootstrap-based feature selection method to identify a robust miRNA-pair signature. The bootstrap-based feature selection improved the stability of feature selection by an ensemble based on the data perturbation. Furthermore, a series of bioinformatics analyses were carried out to explore the potential mechanisms of the signature and potential drug targets for LSCC. RESULTS Based on the REOs of miRNA pairs, we identified a qualitative signature that consisted of 12 miRNA pairs. The constructed signature has good performance in predicting the OS of LSCC patients. It is robust against batch effects and more suitable for individual clinical applications. Furthermore, we identified several hub genes that may be potential drug targets for LSCC. CONCLUSION Overall, our findings provided a promising signature for predicting the OS of LSCC patients.

Abstract
Laryngeal hemangioma is a rare benign tumor of the larynx with predilection for a supraglottal subsite. Common presentations include hoarseness, dyspnea, and dysphagia, with a typical appearance of a reddish-purplish mass. A capillary form of the tumor, lobular capillary hemangioma (LCH) is extremely rare in adults and is predominantly unilateral. Diagnosis is made histologically by the distinct lobular growth pattern of capillary proliferation. Here, we report a 50-year-old male chronic smoker who presented with 3-month history of progressive hoarseness, dry cough, and intermittent dyspnea. Flexible endoscopy of the larynx showed irregular pinkish-white masses on the middle third of the bilateral vocal folds. The provisional diagnosis of glottic carcinoma was ruled out by histopathology, and the final diagnosis was bilateral glottic LCH, making it the first recorded case of this condition in literature. The patient underwent endolaryngeal microsurgery with subepithelial excision, a procedure that can be both diagnostic and therapeutic for this rare tumor.

Abstract
Laryngeal squamous cell cancer (LSCC) accounts for almost 25-30% of all head and neck squamous cell cancers and is clustered according to the affected districts, as this determines distinct tendency to recur and metastasize. A major role for numerous genetic alterations in driving the onset and progression of this neoplasm is emerging. However, major efforts are still required for the identification of molecular markers useful for both early diagnosis and prognostic definition of LSCC that is still characterized by significant morbidity and mortality. Non-coding RNAs appear the most promising as they circulate in all the biological fluids allowing liquid biopsy determination, as well as due to their quick and characteristic modulation useful for non-invasive detection and monitoring of cancer. Other critical aspects are related to recent progress in circulating tumor cells and DNA detection, in metastatic status and chemo-refractoriness prediction, and in the functional interaction of LSCC with chronic inflammation and innate immunity. We review all these aspects taking into account the progress of the technologies in the field of next generation sequencing.

Abstract
Peptide-based drug development is an emerging and promising approach in cancer therapeutics. The present study focuses on understanding the mechanism of MP12 peptide (MDNHVCIPLCPP) derived from cysteine-rich trypsin inhibitor protein of virulence factor of pathogenic fungus Aphanomyces invadans. MP12 is involved in antiproliferative activity against the human laryngeal epithelial cell (Hep-2), demonstrated in this study. MP12 sequence showed a significant binding score and has multiple hydrogen bond interactions with the proteins that play a vital role in apoptotic pathways such as Bcl-2, caspase-3, caspase-7, and XIAP. Based on the bioinformatics characterization and molecular docking result, further study was focused on MP12 antiproliferative activity. The peptide showed a dose-dependent inhibition against Hep-2 cell line proliferation, analyzed over MTT and neutral red uptake assays. The IC50 value of the MP12 peptide was calculated based on the antiproliferative property (24.7 ± 0.34 μM). MP12 treated Hep-2 cells showed significant shrinkage in cell morphology compared to untreated cells, inhibiting the cell cycle. The gene expression analysis validated that the MP12 significantly upregulates the caspase-3, caspase-7, and caspase-9 genes. The developmental toxicity study using zebrafish embryos as in vivo model proved that the MP12 is nontoxic. Based on the obtained results, we proposed that the peptide MP12 derived from cysteine-rich trypsin inhibitor protein of virulence molecule of pathogenic fungus have a potential antiproliferative activity. However, further clinical trials need to be focused on the mechanism and therapeutic application against laryngeal cancer.

Abstract
Alcohol consumption, which affects the structure and composition of the laryngeal microbiota, is one of the most important risk factors for laryngeal squamous cell cancer (LSCC). Our results demonstrated that high enrichment of Fusobacterium nucleatum (F. nucleatum) in LSCC was associated with poor prognosis. F. nucleatum increased miR-155-5p and miR-205-5p expression to suppress alcohol dehydrogenase 1B (ADH1B) and transforming growth factor β receptor 2 (TGFBR2) expression by activating innate immune signaling, resulting in ethanol metabolism reprogramming to allow F. nucleatum accumulation and PI3K/AKT signaling pathway activation to promote epithelial-mesenchymal transition, further exacerbating the uncontrolled progression and metastasis of LSCC. Therefore, the positive feed-forward loop between F. nucleatum and ethanol metabolism reprogramming promotes cell proliferation, migration, and invasion to affect LSCC patient prognosis. The amount of F. nucleatum is a potential prognostic biomarker, which yields valuable insight into clinical management that may improve the oncologic outcome of patients with LSCC.

Abstract
Background Laryngeal squamous cell carcinoma (LSCC) is a leading malignant cancer of the head and neck. Patients with LSCC, in which the cancer has infiltrated and metastasized, have a poor prognosis. Therefore, there is an urgent need to identify more potential targets for drugs and biomarkers for early diagnosis. Methods RNA sequence data from LSCC and patients’ clinical traits were obtained from the Gene Expression Omnibus (GEO) (GSE142083) and The Cancer Genome Atlas (TCGA) database. Differentially expressed gene (DEG) analysis and weighted gene co-expression network analysis (WGCNA) were performed to identify hub genes. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, prognostic value analysis, receiver operating characteristic (ROC) curve analysis, gene mutation analysis, tumor-infiltrating immune cell abundance profile estimation, gene set variation analysis (GSVA), and gene set enrichment analysis (GSEA) were performed. Single-gene RNA sequencing data were obtained from the GSE150321 dataset. Cell proliferation and viability were confirmed by the CCK-8 assay and real-time PCR. Results A total of 701 DEGs, including 329 upregulated and 372 downregulated genes, were screened in the GSE142083 dataset. Using WGCNA, three modules were identified to be closely related to LSCC. After intersecting the DEGs and performing univariate and multivariate Cox analyses, a novel prognostic model based on three genes (SLC35C1, HOXB7, and TEDC2) for LSCC was established. Interfering TEDC2 expression inhibited tumor cell proliferation and migration. Conclusions Our results show that SLC35C1, HOXB7, and TEDC2 have the potential to become new therapeutic targets and prognostic biomarkers for LSCC.

Abstract
OBJECTIVES/HYPOTHESIS Non-squamous cell carcinoma (SCC) malignancies are rare, but well described laryngeal pathologies. However, the epidemiology and clinical behavior of these tumors is not well studied. STUDY DESIGN Retrospective cohort study. METHODS Patients diagnosed with non-squamous cell larynx cancer from 2004 to 2017 in the National Cancer Database were selected. Demographic, clinicopathologic factors, treatments, and survival were analyzed. Univariable and multivariable cox regression were performed. Survival was compared with a propensity score-matched (PSM) population of laryngeal SCC patients. RESULTS A total of 136,235 cases of larynx cancer were identified. After excluding SCC variants, 2,172 (1.6%) patients met inclusion criteria. The most common histology was chondrosarcoma (374, 17.2%), followed by small cell (345, 15.9%), and spindle cell carcinoma (268, 12.3%). The most common treatment was surgery (683, 31.4%) followed by chemoradiation (409, 18.8%) and surgery and adjuvant radiation (288, 13.3%). Overall, 3- and 5-year survival was 67.9% and 59.4%, respectively. In multivariate analysis controlling for age, stage, comorbidity, histology, and treatment modality; chondrosarcoma had the best survival (hazard ratio [HR] 0.11, confidence interval [CI] 0.07-0.19, P < .001). In a PSM population, matched for age, stage, comorbidity, and treatments; non-SCC patients had significantly lower survival (51.5% vs. 59.9%, P < .001). CONCLUSION A diverse range of non-squamous cell malignancies occur in the larynx. In general, these tumors have poor survival, with few exceptions such as chondrosarcoma. While the majority of these histologies undergo surgical-based treatments in other sites, only 53% of patients underwent surgical-based treatment in the larynx. These data could guide clinicians in determining the outcome of treatment in these patients. LEVEL OF EVIDENCE 4 Laryngoscope, 2022.

Abstract
Recently, circular RNAs have been shown to function as critical regulators of many human cancers. However, the circRNA mechanism in laryngeal squamous cell carcinoma (LSCC) remains elusive. Recent investigations using bioinformatics analysis revealed high expression of hsa_circ_0023305 in LSCC tissues compared to normal tissues. Furthermore, we discovered that hsa_circ_0023305 expression level was positively correlated to tumor/node/metastasis (TNM) stage as well as lymph node metastasis in LSCC. Moreover, higher hsa_circ_0023305 levels were correlated to poorer LSCC patient outcomes. Knockdown of hsa_circ_0023305 significantly inhibited LSCC cell proliferation, invasion, and migration abilities. Our team validated that hsa_circ_0023305 functioned as a miR-218-5p sponge from a mechanistic perspective, targeting the melastatin-related transient receptor potential 7 (TRPM7) in LSCC cells. TRPM7 regulates a nonselective cation channel and promotes cancer proliferation and metastasis. Our data demonstrated that miR-218-5p was downregulated in LSCC and that miR-218-5p upregulation repressed LSCC proliferation and invasion both in vivo and in vitro. Additionally, we found that hsa_circ_0023305-mediated upregulation of TRPM7 inhibited miR-218-5p and contributed to LSCC migration, proliferation, and invasion. In summary, these data propose a new mechanism by which the hsa_circ_0023305/miR-218-5p/TRPM7 network enhances LSCC progression.

Abstract
The 5-year survival rate of laryngeal cancer continues to decline, and the laryngeal particularity of the anatomy adversely affects the patient's quality of life. Emerging evidence suggests that long noncoding RNAs (lncRNAs) are closely correlated to key steps in the malignant progression of cancer cells. In this study, we report the role of lncRNA SBF2-AS1/miR-302b-3p/TGFBR2 interactions in the metastasis of laryngeal squamous cell carcinoma (LSCC). We verified that SBF2-AS1 was significantly downregulated in LSCC tissues and cell lines using qRT-PCR analysis. Its low expression was correlated to lymph node metastasis and an advanced clinical stage. More importantly, LSCC patients with low expression of SBF2-AS1 tended to have a poor prognosis. Based on this, we performed gain-of-function and loss-of-function experiments in LSCC cell lines. The results confirmed that knocking down SBF2-AS1 can promote the metastasis of LSCC cells and enhance epithelial-mesenchymal transition phenotype, while the upregulation of SBF2-AS1 expression resulted in the opposite. Our in vivo model verified that SBF2-AS1 overexpression could inhibit LSCC cell metastasis. Subsequent mechanistic studies revealed that SBF2-AS1 acted as a competing endogenous RNA that upregulated the expression of TGFBR2 by endogenous sponging for miR-302b-3p in LSCC cell lines. Moreover, miR-302b-3p overexpression reversed the inhibitory effects on LSCC metastasis induced by upregulation of SBF2-AS1 expression, and inhibition of TGFBR2 expression reversed the effect of SBF2-AS1 on metastasis. Our study proposes SBF2-AS1 as a biomarker to predict the prognosis of LSCC patients and a novel potential therapeutic target.

Abstract
The diaphanous related formin 1 (DIAPH1) protein is involved in the regulation of dynamic cytoskeleton reorganization, which is closely related to mitosis and the cell cycle. Cell cycle disorders are generally regarded as important underlying causes of many cancers. In the current study, we have revealed that DIAPH1 expression is an independent prognostic factor for overall survival in patients with laryngeal squamous cell carcinoma (LSCC) and that DIAPH1 promotes colony formation, cell proliferation, and G1/S progression in LSCC cells. Additionally, DIAPH1 promotes growth of AMC-HN-8 LSCC-derived tumors in vivo. In this study, RNA-sequencing analysis revealed that DIAPH1 knockdown led to changes in the expression of genes associated with signaling during the cell cycle. Using western blot analyses, we further demonstrated that DIAPH1 knockdown resulted in upregulation of p21Waf1/Cip1, p19Ink4d, p27Kip1, and p16Ink4a and downregulation of cyclinA2, cyclinD1, CDK2, CDK4, and CDK6. These results suggest that DIAPH1 influences the expression of genes in several signaling pathways and promotes LSCC progression by regulating the cell cycle.

Abstract
OBJECTIVE The slow spatial encoding of MRI has precluded its application to rapid physiologic motion in the past. The purpose of this study is to introduce a new fast acquisition method and to demonstrate feasibility of encoding rapid two-dimensional motion of human vocal folds with sub-millisecond resolution. METHOD In our previous work, we achieved high temporal resolution by applying a rapidly switched phase encoding gradient along the direction of motion. In this work, we extend phase encoding to the second image direction by using single-point imaging with rapid encoding (SPIRE) to image the two-dimensional vocal fold oscillation in the coronal view. Image data were gated using electroglottography (EGG) and motion corrected. An iterative reconstruction with a total variation (TV) constraint was used and the sequence was also simulated using a motion phantom. RESULTS Dynamic images of the vocal folds during phonation at pitches of 150 and 165 Hz were acquired in two volunteers and the periodic motion of the vocal folds at a temporal resolution of about 600 µs was shown. The simulations emphasize the necessity of SPIRE for two-dimensional motion encoding. DISCUSSION SPIRE is a new MRI method to image rapidly oscillating structures and for the first time provides dynamic images of the vocal folds oscillations in the coronal plane.

Abstract
Laryngeal carcinoma is the second common malignancy of the upper aerodigestive tract after lung cancer; in most cases is a squamous cell carcinoma, whose risk factors include tobacco smoking and alcohol consumption. Despite therapeutic progress, the five-year overall survival rate for this malignancy has remained nearly 50% and many patients already present metastasis at the time of diagnosis. To date, there are no tools that predict the evolution of laryngeal carcinoma: in this light, during the last years, many studies were planned with the aim to investigate the role played by different biomarkers expressed by larynx cancer, which can help make an early diagnosis, predict disease evolution and direct therapeutic choice. This review aims to summarize these markers and correlating them with disease evolution.

Abstract
INTRODUCTION Laryngeal squamous cell carcinoma (LSCC) is diverse in its natural history and responsiveness to treatments. There is an urgent need to generate candidate biomarkers for the stratification and individualization of treatment to avoid overtreatment or inadequate treatment. Long noncoding RNA nuclear paraspeckle assembly transcript 1 (NEAT1) has been identified as an oncogenic gene in multiple human tumors entitles, and dysregulation of NEAT1 was tightly linked to carcinogenesis and cancer progression. METHODS One hundred two paraffin samples of LSCC patients were collected. Furthermore, in situ hybridization (ISH), Kaplan-Meier, and MTT were used to analyze the relationship between NEAT1 and the progress of LSCC. RESULTS In this study, ISH revealed that NEAT1 was strongly expressed in the nucleus. The increased expression of NEAT1 was correlated with T grade, neck nodal metastasis, clinical stage, drinking history, or smoking history of LSCC. The Kaplan-Meier analysis indicated that patients with higher NEAT1 expression had a worse overall survival in LSCC patients. In addition, NEAT1 knockdown significantly inhibited the growth of LSCC cells. CONCLUSION Together, these results suggested that NEAT1 involved in the progress of LSCC and might act as a tumor oncogenic gene. This study provides a potential new marker and target for gene therapy in the treatment of LSCC.

Abstract
Circular RNAs (circRNAs) are implicated in the tumorigenesis of human cancers. However, the effects of circRNAs on laryngeal squamous cell carcinoma (LSCC) are largely unknown. Here, we aimed to explore the roles of circ_0023028 in LSCC development. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to measure circ_0023028, miR-486-3p, and Lin-Isl-Mec (LIM) and SH3 domain protein 1 (LASP1) mRNA. The characteristics of circ_0023028 were determined by RNase R digestion assay and Actinomycin D assay. Cell Counting Kit-8 (CCK-8) assay and colony formation assay were utilized for cell proliferation. Transwell assay was adopted for cell invasion and migration. Flow cytometry analysis was carried out to analyze cell cycle and apoptosis. RNA pull-down assay and dual-luciferase reporter assay were used to explore the association between miR-486-3p and circ_0023028 or LASP1. Western blot assay was adopted to measure LASP1 protein level. Murine xenograft model was executed to investigate the function of circ_0023028 in vivo. High expression of circ_0023028 was observed in LSCC tissues and cells. Circ_0023028 was stable and possessed a loop structure. Circ_0023028 silencing suppressed LSCC cell proliferation, metastasis and cell cycle process and induced apoptosis in vitro and hampered tumor growth in vivo. Further mechanism analysis demonstrated that circ_0023028 could sponge miR-486-3p to regulate LASP1 expression in LSCC cells. The malignant behaviors of LSCC cells mediated by circ_0023028 knockdown were rescued by the inhibition of miR-486-3p. Moreover, miR-486-3p suppressed LSCC cell progression via binding to LASP1. Circ_0023028 knockdown might impede the progression of LSCC by regulating miR-486-3p/LASP1 axis, which could provide a novel insight on the mechanism of LSCC progression.

Abstract
Purpose Long noncoding RNAs growth arrest-specific 5 (GAS5) exerts important functions in modulating various tumor behaviors. However, the role of lncRNA GAS5 in laryngeal squamous cell carcinoma (LSCC) remains unknown. Materials and Methods Cell viability and apoptosis were, respectively, detected by cell counting kit-8 and flow cytometry, DIANA-LncBase V, Starbase, TargetScan and a dual-luciferase reporter gene assay were employed to assess the relationship among GAS5, miR-26a-5p and uncoordinated 51-like kinase 1 (ULK2), and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blot were performed to detect the expression of autophagy-relative factors. Results The expression level of GAS5 was frequently decreased in LSCC cell lines, and up-regulated GAS5 inhibited AMC-HN-8 cells viability and induced apoptosis. More importantly, we found that GAS5 activated autophagy, with enhanced autophagy-related proteins after GAS5 overexpression. While down-regulated GAS5 had opposite results in Tu 177 cells, GAS5 was found to act as a microRNA sponge in a pathway to regulate miR-26a-5p and its target gene ULK2. MiR-26a-5p mimics inhibited apoptosis and autophagy, which were reversed by GAS5 and siGAS5 in AMC-HN-8 cells and Tu 177 cells, as well as ULK2 in AMC-HN-8 cells. Meanwhile, the concomitant downregulation of ULK2 and miRNA-26a-5p inhibitor decreased the miRNA-26a-5p inhibitor-induced apoptosis and autophagy. Conclusion This is the first report of LncRNA GAS5 acting as a tumor suppressor in LSCC by regulating the miR-26a-5p/ULK2 axis, and it could be a new target for gene therapy in LSCC.

Abstract
Accumulating evidence indicates that the long non-coding RNA myocardial infarction associated transcript (lncRNA MIAT) serves an important role in the progression of a number of cancer types. However, the precise molecular mechanism of MIAT in laryngeal squamous cell carcinoma (LSCC) progression remain elusive. The aim of the current study was to assess the effects and to clarify the molecular mechanism of MIAT on the proliferation and invasion of LSCC cells. The expression of MIAT was detected in LSCC tissues and cells using reverse transcription-quantitative PCR. MTT and colony formation assays were performed to examine the effects of MIAT on the proliferation of LSCC cells. Additionally, wound healing and Transwell experiments were employed to examine cellular migration and invasion. Luciferase reporter gene assay was also used to confirm the direct binding between MIAT and microRNA (miR)-613 in LSCC cells. An RNA immunoprecipitation assay was performed to verify the interaction between MIAT and miR-613. In the present study, it was found that the expression of MIAT in LSCC tissues was markedly higher compared with that in adjacent non-tumor tissues. In addition, MIAT expression was also increased in the human LSCC cell lines TU686, TU-177 and AMC-HN-8 compared with that in normal human keratinocytes (HaCaT). Knocking down MIAT expression significantly reduced LSCC cell proliferation and inhibited colony formation, a shown by MTT and colony formation assays, respectively. MIAT knockdown also substantially inhibited the migratory and invasive abilities of LSCC cells, as shown by wound healing and Transwell invasion assays, respectively. Subsequently, luciferase reporter assays verified that MIAT could bind to miR-613, where a negative correlation was observed between the expression of MIAT and miR-613 in LSCC tissues. Suppression of miR-613 partially reversed the inhibitory effects of MIAT knockdown on the proliferation, migration and invasion of LSCC cells. Taken together, the present study identified that MIAT may function as an oncogenic lncRNA to promote LSCC progression, which provides a potential therapeutic target or as a novel diagnostic biomarker for LSCC.

Abstract
Metastases lead to high mortality in laryngeal cancer, but the regulation of its underlying mechanisms remains elusive. We identified Protein arginine methyltransferase 5 (PRMT5) was significantly up‐regulated in laryngeal cancer tissues, which predicts poor patient prognosis. Functional assays demonstrated that PRMT5 overexpression promoted the invasive capacity and lymph node metastasis in vitro and in vivo. Mechanistic experiments suggested that LATS2 was a downstream target of PRMT5. PRMT5 inhibition increased the expression of LATS2 and YAP phosphorylation in laryngeal cancer cells, thereby promoting laryngeal cancer metastasis. Furthermore, informatics and experimental data confirmed that PRMT5 gene was transcriptionally activated by YY1. Collectively, our results unravelled the important role of PRMT5 in laryngeal cancer tumorigenesis and metastasis. The dysregulation YY1/PRMT5/LATS2/YAP axis may contribute to laryngeal cancer progression; thus, PRMT5 may be a potential therapeutic strategy for patients with laryngeal cancer.

Abstract
With rapid development of science technique and molecular research, a large number of circular RNAs (circRNAs) were discovered. CircRNAs that are a heterogeneous endogenous group of non-coding RNA not only are abundantly and diffusely expressed in mammals but also participate in many biological processes, such as in tumor ingenuity and progress. CircRNAs have rarely open reports in the head and neck cancers (HNC), which are an aggressive malignant tumor with unsatisfactory overall survival rates. The diagnostics and treatments continue to improve while the survival rate of HNC patients has no more obvious improvement. Recent studies that are aimed at exploring the molecular mechanisms of occurrence and progression of circRNAs in HNC provide a valuable insight into potential novel diagnostic and therapeutic approaches. In this review, we summarize the increasing number of published researches on the research progression of circRNAs in HNC, as well as their possible clinical implications on HNC.

[PMID: 32900505 DOI: 10.1016/j.bja.2020.07.051] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Revised: 07/30/2020] [Accepted: 07/30/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Expression of the mu-opioid receptor (MOR) is associated with poor long-term outcomes in various types of cancer. The association between MOR expression and clinical outcomes in laryngeal squamous cell carcinoma (LSCC) is not clear. METHODS This retrospective study included patients who underwent laryngectomy for LSCC. The expression pattern of the MOR protein and OPRM1 gene in tumours and corresponding adjacent non-carcinoma specimens was measured. Propensity score matching was used to minimise bias. The primary endpoints were overall survival (OS) and disease-free survival (DFS). The secondary endpoints were intraoperative sufentanil consumption, grade of surgical complications according to the Clavien-Dindo classification, and hospital length of stay. RESULTS A total of 207 LSCC patients were enrolled. After propensity score matching, there was a significant difference in DFS between groups at 1, 3, and 5 yr (60.2% vs 81.2%, P=0.019; 39.4% vs 50.2%, P=0.026; 37.5% vs 42.5%, P=0.023, respectively) in patients with high MOR expression. The OS rates at 1, 3, and 5 yr were significantly lower in the high MOR expression group (81.2% vs 93.2%, P=0.027; 57.7% vs 78.3%, P<0.001; 42.5% vs 60.3%, P<0.001, respectively). The multivariate analysis indicated that high MOR expression was associated with worse DFS and OS (hazard ratio: 1.52, 95% confidence interval: 1.07, 2.25, P=0.034; hazard ratio: 1.42, 95% confidence interval: 1.17, 2.34, P=0.032). CONCLUSION High MOR expression may be associated with poor prognosis in patients with LSCC, suggesting that MOR could be used as a valuable molecular biomarker to predict prognosis of LSCC patients.

Abstract
AIMS To investigate the clinical features, treatment, and outcomes of laryngeal spindle cell carcinoma (SpCC). METHODS Between 2005 and 2014, patients from our hospital with SpCC of the larynx were retrospectively analyzed alongside patient data from the SEER database of America. RESULTS A total of 11 patients with SpCC of the larynx were diagnosed and underwent surgery in our hospital. All patients were male and all tumors were located in the glottis. The 3- and 5-year OS rates were both 54.5%. In the SEER database, 148 patients were diagnosed with SpCC of the larynx. The 3- and 5-year OS rates were 72.8 and 63.2%, respectively. According to the comparison of propensity score-matched analysis, the OS was longer in squamous cell carcinoma (SCC) of the larynx (p < 0.0001). CONCLUSION SpCC of the larynx is rare and typically originates in the glottis. Its prognosis is worse than that of laryngeal SCC, and surgery is a reasonable treatment strategy.

Abstract
Cancer causes most of the mortality and morbidity worldwide, with a significant increase in incidence during recent years. MicroRNAs (miRNAs/miRs) are non-coding small RNAs capable of regulating gene expression. They regulate crucial cellular processes, including proliferation, differentiation, metastasis and apoptosis. Therefore, abnormal miRNA expression is associated with multiple diseases, including cancer. There are two types of cancer-associated miRNAs, oncogenic and tumor suppressor miRNAs, depending on their roles and expression patterns in cancer. Accordingly, miRNAs are considered to be targets for cancer prevention and treatment. miR-33a controls cellular cholesterol uptake and synthesis, which are both closely associated with carcinogenesis. The present review thoroughly describes the roles of miR-33a in more than a dozen types of cancer and the underlying mechanisms. Accordingly, the present review may serve as a guide for researchers studying the involvement of miR-33a in diverse cancer settings.

Early Glottic Cancer Treated by Transoral Laser Surgery Using Toluidine Blue for the Definition of the Surgical Margins: A Pilot Study. ACTA ACUST UNITED AC 2020; 56:medicina56070334. [PMID: 32635245 PMCID: PMC7404472 DOI: 10.3390/medicina56070334] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 06/29/2020] [Accepted: 06/30/2020] [Indexed: 11/25/2022]
Abstract
Background and objectives: Transoral laser microsurgery (TLM) is widely accepted for its advantages, which consist of a brief hospital stay, rapid functional recovery, low management costs and the fact that it can be easily repeated in cases of recurrence. However, a high incidence of positive or narrow surgical margins has been reported in the literature, even if controversy still exists on the prognostic significance of positive resection margins. The aim of the study was to evaluate the utility of toluidine blue staining in defining the resection margins of early glottic cancer (T1a–T2) treated with TLM. Materials and Methods: This retrospective study was conducted on patients with early glottic cancer (T1a–T2) managed by TLM. A group of patients treated between 2010 and 2014 underwent toluidine blue staining (TB group) of the lesions before starting the cordectomy by TLM, and a group of patients treated by TLM between 2006 and 2009 was considered the control group. Results: A total of 44 subjects were included in this study: 41 were men, and 3 were women. The mean age was 58 ± 9.0 years (median 59.0, range 41–77). Twenty-three of the 44 patients were included in the TB group and 21 in the case control group. In the TB group, only the positivity of the deep margin was a predictor of local recurrence (p = 0.037), while in the control group, positive or close margins and the type of cordectomy were predictive factors of local recurrence (p = 0.049). Considering the TB group and control cases, the 5-year local recurrence-free survival was 95.6% and 80.9%, respectively (p = 0.14). Conclusions: From this first study, toluidine blue staining seems to be a useful modality to improve the rate of the negative resection margins of early glottic cancer (T1a–T2) treated by TLM.

Abstract
Objective Laryngeal cancer is a common malignant tumor in the ENT, of which laryngeal squamous cell carcinoma (LSCC) accounts for more than 90% of laryngeal cancer. The purpose of this study is to investigate the regulatory mechanism of lncRNA SNHG16 in LSCC. Materials and Methods Real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) was used to measure mRNA expression. Cell Counting Kit (CCK-8), Transwell and luciferase reporter assays, flow cytometric analysis and Western blot analysis were used to investigate the function of lncRNA SNHG16 in LSCC. Results SNHG16 expression was increased in LSCC tissues and cells. The abnormal expression of SNHG16 was associated with clinical stage and lymph node metastasis in LSCC patients. In addition, knockdown of SNHG16 restrained cell proliferation, migration and invasion in LSCC. More importantly, SNHG16 acted as a competitive endogenous RNA in LSCC and regulated FOXP4 expression by making miR-877-5p sponge. Further, SNHG16 promoted LSCC progression by interacting with miR-877-5p and FOXP4. Conclusion LncRNA SNHG16 promotes the progression of LSCC by sponging miR-877-5p and upregulating FOXP4.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is a genetically complex tumor type and one of the leading causes of cancer-associated disability and mortality. Genetic instability, such as chromosomal instability, is associated with the tumorigenesis of LSCC. Copy number variations (CNVs) have been demonstrated to contribute to the genetic diversity of tumor pathogenesis. Comparative genomic hybridization (CGH) has emerged as a high-throughput genomic technology that facilitates the aggregation of high-resolution data of cancer-associated genomic imbalances. In the present study, a total of 38 primary supraglottic LSCC cases were analyzed by high-resolution array-based CGH (aCGH) to improve the understanding of the genetic alterations in LSCC. Additionally, integration with bioinformatic analysis of microarray expression profiling data from the Gene Expression Omnibus (GEO) database provided a fundamental method for the identification of putative target genes. Genomic CNVs were detected in all cases. The size of net genomic imbalances per case ranged between a loss of 682.3 Mb (~24% of the genome) and a gain of 1,958.6 Mb (~69% of the genome). Recurrent gains included 2pter-q22.1, 3q26.1-qter, 5pter-p12, 7p22.3p14.1, 8p12p11.22, 8q24.13q24.3, 11q13.2q13.4, 12pter-p12.2, 18pter-p11.31 and 20p13p12.1, whereas recurrent losses included 3pter-p21.32, 4q28.1-q35.2, 5q13.2-qter, 9pter-p21.3 and monosomy 13. Gains of 3q26.1-qter were associated with tumor stage, poor differentiation and smoking history. Additionally, through integration with bioinformatic analysis of data from the GEO database, putative target oncogenes, including sex-determining region Y-box 2, eukaryotic translation initiation factor 4 gamma 1, fragile X-related gene 1, disheveled segment polarity protein 3, defective n cullin neddylation 1 domain containing 1, insulin like growth factor 2 mRNA binding protein 2 and CCDC26 long non-coding RNA, and tumor suppressor genes, such as CUB and sushi multiple domains 1, cyclin dependent kinase inhibitor 2A, protocadherin 20, serine peptidase inhibitor Kazal type 5 and Nei like DNA glycosylase 3, were identified in supraglottic LSCC. Supraglottic LSCC is a genetically complex tumor type and aCGH was demonstrated to be effective in the determination of molecular profiles with higher resolution. The present results enable the identification of putative target oncogenes and tumor suppressor gene mapping in supraglottic LSCC.

Abstract
Reliable diagnosis and efficient targeted therapy are important and may lead to the effective treatment of laryngeal carcinoma. Multifunctional nano-theranostic agents demonstrate great potential in tumor theranostic applications. Thus, herein, we report novel targeting multifunctional theranostic nanoparticles, internalized RGD (iRGD)-modified indocyanine green (ICG) encapsulated liposomes (iLIPICG), for imaging-guided photothermal therapy (PTT) and photodynamic therapy (PDT) for the treatment of laryngeal carcinoma. The iRGD-PEG-DSPE lipid endowed iLIPICG with high affinity for tumor vascular targeting, tumor-penetration and tumor cell targeting. The in vivo results showed that iLIPICG exhibited excellent blood circulation and tumor accumulation. iLIPICG could be spatially and temporally controlled, simultaneously producing hyperthermia and reactive oxygen species as well as a fluorescence-guided effect through ICG to ablate laryngeal carcinoma cells under irradiation from an 808 nm laser. iLIPICG generated synergistic photodynamic-photothermal cytotoxicity against Hep-2 cells, resulting in the efficient ablation of laryngeal carcinoma. Thus, the iLIPICG system provides a promising strategy to improve the precision imaging and effective phototherapy for the treatment of laryngeal carcinoma.

Abstract
Recently, abundant evidence has clarified that long noncoding RNAs (lncRNAs) play an oncogenic or anticancer role in the tumorigenesis and development of diverse human cancers. Described as a crucial regulator in some cancers, MIR22HG has not yet been studied in laryngocarcinoma and therefore the underlying regulatory role of MIR22HG in laryngocarcinoma is worth detecting. In this study, MIR22HG expression in laryngocarcinoma cells was confirmed to be downregulated, and upregulated MIR22HG expression led to suppressive effects on laryngocarcinoma cell proliferation and migration. Molecular mechanism assays revealed that MIR22HG sponges miR-5000-3p in laryngocarcinoma cells. Besides, decreased expression of miR-5000-3p suppressed laryngocarcinoma cell proliferation and migration. Moreover, the FBXW7 gene was reported to be a downstream target gene of miR-5000-3p in laryngocarcinoma cells. More importantly, rescue assays verified that FBXW7 depletion or miR-5000-3p upregulation countervailed the repressive effects of MIR22HG overexpression on laryngocarcinoma progression. In addition, E2F6 was proved to be capable of inhibiting MIR22HG transcription in laryngocarcinoma cells. To sum up, E2F6-induced downregulation of MIR22HG promotes laryngocarcinoma progression through the miR-5000-3p/FBXW7 axis.

Abstract
Laryngeal cancer (LCa), a neoplasm of the head and neck region, is a leading cause of death worldwide. Surgical intervention remains the mainstay of LCa treatment, but a crucial point is represented by the possible nodal involvement. Therefore, it is urgently needed to develop biomarkers and therapeutic tools able to drive treatment approaches for LCa. In this study, we investigated deregulated microRNAs (miRNAs) in tissues from LCa patients with either lymph node metastases (N+) or not (N−). miRNA expression profiling was performed by a comprehensive PCR array and subsequent validation by RT-qPCR. Results showed a significant decrease of miR-449a expression in N+ compared to N− patients, and miR-133b down-modulation in LCa tissues compared to paired normal ones. Receiver operating characteristic (ROC) curve analysis revealed the potential diagnostic power of miR-133b for LCa detection. According to the validation results, we selected miR-449a for further in vitro studies. Ectopic miR-449a expression in the LCa cell line Hep-2 inhibited invasion and motility in vitro, slowed cell proliferation, and induced the downregulation of Notch1 and Notch2 as direct targets of miR-449a. Collectively, this study provides new promising biomarkers for LCa diagnosis and a new opportunity to use miR-449a for the treatment of nodal metastases in LCa patients.

Purpose Laryngeal cancer is the most prevalent tumor type in head and neck cancers. Early diagnosis is considered as an important strategy for improving prognosis. The lncRNA DLX6-AS1 has been shown to modulate tumor phenotypes in several types of cancer, but the role of DLX6-AS1 in laryngeal cancer and its concrete mechanisms are not clear. Methods Tissue samples from laryngeal cancer patients and corresponding clinical data were used for detailed analysis. The laryngeal cancer cell lines HEp-2 and Tu-177 were studied. Cell proliferation, ROS production, mitochondrial respiratory function, intracellular and mitochondrial calcium influx were assessed. Western blotting, quantitative RT-PCR and luciferase assays were used to analyze the interactions. A xenografted tumor model was established to analyze the effects of DLX6-AS1 on tumor growth in vivo. Results lncRNA DLX6-AS1 had increased expression in tumor tissues compared with adjacent normal tissues and in higher clinical stages compared with lower stages, which was associated with poor prognosis. In detail, DLX6-AS1 knockdown decreased cell proliferation and affected key mitochondrial metabolic parameters in both HEp-2 and Tu-177 cells. Moreover, DLX6-AS1 knockdown suppressed TRPC3-mediated mitochondrial calcium uptake and ROS production. Furthermore, miR-26a functioned as a link between these two molecules, as it could be absorbed by DLX6-AS1 and thus regulated the levels of TRPC3. Finally, the DLX6-AS1/miR-26a/TRPC3 axis modulated laryngeal cancer proliferation both in vitro and in vivo. Conclusion This study provides new evidence that a novel lncRNA, DLX6-AS1, regulates mitochondrial calcium homeostasis, respiration and tumor proliferation via modulating the miR-26a/TRPC3 axis in laryngeal cancer.

Pathol Res Pract 2020; 216:152974. [PMID: 32370989 DOI: 10.1016/j.prp.2020.152974] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 04/11/2020] [Accepted: 04/13/2020] [Indexed: 12/15/2022]
Abstract
OBJECTIVE The aim of the study was to investigate the expression of ribonuclear protein IMP3 in laryngeal carcinogenesis, together with other biomarkers of carcinogenesis (Ki-67, p53 and cyclin D1), and to evaluate their predictive values. METHODS The study included 153 patients divided into three groups: 68 operated for primary invasive laryngeal squamous cell carcinoma (LSCC); 41 with precancerous lesions of atypical and abnormal hyperplasia; 44 with hyperplastic laryngeal nodule without atypia. Tissue microarray technique was used for immunohistochemical analysis. RESULTS All markers showed statistically significant differences between the three groups. The percentage of IMP3 positive cells is statistically significantly higher in LSCC group in comparison to precancerosis and control group. The percentage of Ki-67 positive cells is statistically significantly higher in LSCC group in comparison to precancerosis and control group. The percentage of p53 positive cells in LSCC group is statistically significantly higher than the control group and higher, but not statistically significant, than the precancerosis group. The percentage of cyclin D1 positive cells is statistically significantly higher in LSCC group than in precancerosis group and higher, but not statistically significant, than in the control group. All analyzed markers have good predictive values (AUC > 0.6), but the percentage of IMP3 positive cells is the only statistically significant marker in predicting whether the patient has LSCC or not. CONCLUSION Expression of Ki-67 and pronouncedly IMP3 generally follow the same pattern where control and precancerosis are similar and LSCC significantly differs, as opposed to p53 and cyclin D1. IMP3 expression increase possibly has an important diagnostic, therapeutic (in terms of the need for additional therapy after surgery) and prognostic value. Further studies on the exact molecular mechanisms behind it are, of course, needed.
