Abstract
BACKGROUND Narrow-band imaging (NBI) endoscopy is used in various tumor detection and is important in detecting early tumors. OBJECTIVE To explore the application value of NBI endoscopy in diagnosing pharyngeal tumors. MATERIAL AND METHODS Ninety-one patients with pharyngeal masses who attended the Department of Otorhinolaryngology, Head and Neck Surgery in Gansu Provincial Hospital from January 2023 to February 2024 were selected, and NBI and white light (WL) endoscopy were applied to examine the pharynx and the relationship between the two was observed. SPSS 25.0 software was used for statistical analysis. RESULTS The sensitivity of NBI endoscopy for diagnosing laryngeal malignant lesions was 92.0 %, the specificity was 93.0 %, the positive predictive value was 88.5 %, and the negative predictive value was 95.2 %, with a high degree of concordance between the results of NBI endoscopy and the pathology; WL endoscopy had a sensitivity of 64.0 %, a specificity of 76. 7 %, a positive predictive value of 61.5 %, and a negative predictive value of 78.6 %, with WL endoscopic findings had moderate concordance with pathology. The diagnostic accuracy of NBI endoscopy was higher than that of WL endoscopy for both benign and malignant lesions and precancerous lesions. CONCLUSION NBI endoscopy can detect laryngeal cancer lesions more accurately.

Wu Z, Zhu Z, Fu L. Integrating GEO, network pharmacology, and in vitro assays to explore the pharmacological mechanism of Bruceae Fructus against laryngeal cancer. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024; 397:4165-4181. [PMID: 38032489 PMCID: PMC11111496 DOI: 10.1007/s00210-023-02869-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 11/21/2023] [Indexed: 12/01/2023]
Abstract
The goal of this study is to look into the pharmacological mechanism of Bruceae Fructus in conjunction with GEO, network pharmacology, and in vitro assays for the treatment of laryngeal cancer to provide theoretical support for its therapeutic use. The active components and matching targets of Bruceae Fructus were retrieved from the TCMSP database, while genes linked with laryngeal cancer were obtained from the GEO, GeneCards, DisGeNET, and DrugBank databases. Besides, the components and targets were supplemented by literatures in PubMed database. Cytoscape software was used to create the active ingredients-target network diagram. The String database was used to build the PPI network. Following that, the core targets were subjected to GO enrichment and KEGG pathway analysis using the DAVID database. Finally, AutoDock was used to perform molecular docking between the core components and the core targets. To investigate the biological effects of beta-sitosterol, the viability of laryngeal cancer cells was assessed after beta-sitosterol therapy using the MTS technique. Following that, how beta-sitosterol affected colony formation after 14 days of culture of treated cells was researched. Flow cytometry was utilized to detect apoptosis to examine the influence of beta-sitosterol on laryngeal cancer cell apoptosis, and then detected mRNA and protein expression levels of 10 key genes by RT-qPCR and Western Blot assay. There were 1258 laryngeal cancer-related genes and 15 Bruceae Fructus components, with beta-sitosterol and luteolin serving as key components. Bruceae Fructus' primary targets against laryngeal cancer were IL6, JUN, TNF, IL2, IL4, IFNG, RELA, TP53, CDKN1A, and AKT1. GO enrichment yielded 41 CC, 78 MF, and 383 BP. Platinum drug resistance, the PI3K-Akt signaling pathway, the p53 signaling pathway, apoptosis, the HIF-1 signaling pathway, and 147 additional pathways have been added to KEGG. The results of molecular docking revealed that the core components had a high affinity for the core target. The results of the cell experiment indicate that beta-sitosterol suppressed Hep-2 cell activity in a concentration-dependent manner. Besides, beta-sitosterol has powerful antiproliferative properties in Hep-2 cells. Flow cytometry results showed that beta-sitosterol promoted laryngeal cancer cell apoptosis in a concentration-dependent manner. The results of RT-qPCR and Western Blot assay showed that the mRNA and protein expression levels of TP53, JUN, TNF-α, CDKN1A, and IL-2 were significantly up-regulated after beta-sitosterol treatment, while the mRNA and protein expression levels of RELA, AKT1, IL-6, IFNG, and IL-4 were significantly down-regulated. This study integrating GEO, network pharmacology, and in vitro assays investigated the probable mechanism of Bruceae Fructus' anti-laryngeal cancer activity, which can give a theoretical foundation for additional future animal experiments.

Construction of a novel disulfidptosis-related lncRNAs signature for prognosis prediction and anti-tumor immunity in laryngeal squamous cell carcinoma. Heliyon 2024; 10:e30877. [PMID: 38774325 PMCID: PMC11107247 DOI: 10.1016/j.heliyon.2024.e30877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 04/09/2024] [Accepted: 05/07/2024] [Indexed: 05/24/2024] Open
Abstract
Disulfidptosis, an innovative type of controlled cellular death linked to metabolic dysfunction, has garnered attention. However, there is limited knowledge regarding the involvement of disulfidptosisrelated lnRNAs (DRlncRNAs) in laryngeal squamous cell carcinoma (LSCC). The objective of our team in this study seeks to establish a DRlncRNAs signature, investigate their prognostic value in LSCC, and explore their associations with immune cell subpopulations, biological signaling pathways, and exploring implications for drug sensitivity. We accessed LSCC patients' RNA-seq data and pertinent clinical data for subsequent further analysis from The Cancer Genome Atlas (TCGA) portal. A literature search was conducted focusing on disulfidptosis-related genes. Pearson correlation coefficients were calculated to identify DRlncRNAs. Differential expression analysis of lncRNAs was performed. Utilizing univariate Cox regression analysis, we identified disulfidptosis-associated prognostic lncRNAs. The LASSO-Cox regression analysis was employed to refine this set of lncRNAs and construct a disulfidptosis-related lncRNAs signature. Various statistical techniques were employed to appraise model predictive performance. Subsequently, risk groups were stratified based on the risk score derived from the DRlncRNAs signature. The superiority of the risk score in prognostication over traditional clinicopathological features in LSCC patients was demonstrated. Evident distinctions emerged between risk groups, particularly in immune cell subpopulations like activated mast cells, eosinophils, and activated NK cells. Finally, the low-risk group demonstrated reduced IC50 values for specific chemotherapeutics like cisplatin and gemcitabine. The in vitro experiments indicated differential behavior of our DRlncRNAs. The DRlncRNAs signature can serve as a robust biomarker with the ability to predict both prognosis and therapeutic responses among patients with LSCC.

Abstract
BACKGROUND The lack of screening methods for LSCC is a critical issue, as treatment options and the treatment outcome greatly depend on the stage of LSCC at initial diagnosis. Therefore, the objective of this study was to identify potential exosomal serum biomarkers that can diagnose LSCC and distinguish between early- and late-stage disease. METHODS A multiplexed proteomic array was used to identify differentially expressed proteins in exosomes isolated from the serum samples of LSCC patients compared to the control group (septorhinoplasty, SRP). The most promising proteins for diagnosis and differentiation were calculated using biostatistical methods and were validated by immunohistochemistry (IHC), Western blots (WB), and ELISA. RESULTS Exosomal insulin-like growth factor binding protein 7 (IGFBP7) and Annexin A1 (ANXA1) were the most promising exosomal biomarkers for distinguishing between control and LSCC patients and also between different stages of LSCC (fold change up to 15.9, p < 0.001 for all). CONCLUSION The identified proteins represent potentially novel non-invasive biomarkers. However, these results need to be validated in larger cohorts with a long-term follow-up. Exosomal biomarkers show a superior signal-to-noise ratio compared to whole serum and may therefore be an important tool for non-invasive biomarker profiling for laryngeal carcinoma in the future.

Abstract
OBJECTIVE Currently, there are few practical tools for predicting the prognosis of laryngeal squamous cell carcinoma (LSCC). This study aims to establish a model and a convenient online prediction platform to predict whether LSCC patients will survive 5 years after diagnosis, providing a reference for further evaluation of patient prognosis. METHODS This is a retrospective study based on data collected from two centers. Center 1 included 117 LSCC patients with survival prognosis data, and center 2 included 33 patients, totaling 150 patients. All data were divided into independent training sets (60 %) and testing sets (40 %). Eight machine learning (ML) algorithms were used to establish models with 11 clinical parameters as input features. The accuracy, sensitivity, specificity, and receiver operating characteristic curve (ROC) of the testing set were used to evaluate the models, and the best model was selected. The model was then developed into a website-based 5-year survival status prediction platform for LSCC. In addition, we also used the SHapley Additive exPlanations (SHAP) tool to conduct interpretability analysis on the parameters of the model. RESULTS The LSCC 5-year survival status prediction model using the support vector machine (SVM) algorithm achieved the best results, with accuracy, sensitivity, specificity, and area under the ROC curve (AUC) of 85.0 %, 87.5 %, 75.0 %, and 81.2 % respectively. The online platform for predicting the 5-year survival status of LSCC based on this model was successfully established. The SHAP analysis shows that the clinical stage is the most important feature of the model. CONCLUSION This study successfully established a ML model and a practical online prediction platform to predict the survival status of laryngeal cancer patients after 5 years, which may help clinicians to better evaluate the prognosis of LSCC.

Abstract
Laryngeal squamous cell carcinoma (LSCC) has the highest mortality rate among head and neck squamous cell carcinoma. This study was designed to investigate the biological effect of long noncoding RNA (lncRNA) MSC antisense RNA 1 (MSC-AS1) on LSCC development and the underlying mechanism. The expression and prognostic value of lncRNAs in head and neck squamous cell carcinoma were predicted in the bioinformatics tools. The overexpression of MSC-AS1 in LSCC patients predicted a poor prognosis. Depletion of MSC-AS1 using shRNA repressed the malignant phenotype of AMC-HN-8 and TU-177 cells. MSC-AS1, mainly localized in the nucleus, interacted closely with the transcription factor CCCTC-binding factor (CTCF). CTCF played anti-tumor effects in vitro and in vivo. Ataxin-7 (ATXN7) was predicted to be a downstream target of CTCF, whose expression was negatively controlled by MSC-AS1. MSC-AS1 was found to block the expression of CTCF, thereby repressing ATXN7. Finally, MSC-AS1 overexpression in LSCC was governed by YTH domain-containing protein 1 (YTHDC1)-mediated m6A modification. In summary, our research identified the YTHDC1/MSC-AS1/CTCF/ATXN7 axis in LSCC development, which indicated that MSC-AS1 is an attractive biomarker in the LSCC treatment.

Abstract
Human laryngeal squamous carcinoma (LSCC) is a common malignant tumor in the head and neck. Despite the recently developed therapies for the treatment of LSCC, patients' overall survival rate still did not enhance remarkably; this highlights the need to formulate alternative strategies to develop novel treatments. The antitumor effects of antidepressant drugs such as citalopram have been reported on several cancer cells; however, they have yet to be investigated against LSCC. The current study was directed to explore the possible antitumor effects of citalopram on human laryngeal carcinoma cell lines (HEP-2). HEP-2 cells were cultured and treated with different doses of citalopram (50-400 µM) for 24, 48, and 72 h. The effects of citalopram on the viability of cancer cells were determined by the MTT assay. In addition, apoptosis and cell cycle analysis were performed by flow cytometry. Moreover, evaluation of the expression of proapoptotic and apoptotic proteins, such as cytochrome c, cleaved caspases 3 and 9, Bcl-2, and BAX, was performed by western blotting analysis. Our results revealed that citalopram significantly suppressed the proliferation of HEP-2 cells through the upregulation of p21 expression, resulting in the subsequent arrest of the cell cycle at the G0/G1 phase. Furthermore, citalopram treatment-induced HEP-2 cell apoptosis; this was indicated by the significant increase of cytochrome c, cleaved caspases 3 and 9, and BAX protein expression. On the contrary, Bcl-2 protein expression was significantly downregulated following treatment with citalopram. The ultrastructure studies were in accordance with the protein expression findings and showed clear signs of apoptosis with ring chromatin condensation upon treatment with citalopram. These findings suggest that citalopram's anti-tumor activities on HEP-2 cells entailed stimulation of the intrinsic apoptotic pathway, which was mediated via Bcl-2 suppression.

Abstract
The aims of this exploratory study and clinical phase II trial were to assess the specific nature and extent of dysphagia in laryngectomized patients with self-reported dysphagia, and its rehabilitation potential using the novel Swallowing Exercise Aid (SEA 2.0). Twenty laryngectomized patients participated in a six-week exercise program with the SEA 2.0. Exercises consisted of Chin Tuck Against Resistance (CTAR), Jaw Opening Against Resistance (JOAR), and Effortful Swallow Against Resistance, conducted three times per day. Swallowing was assessed at baseline (T0), six (T1) and 14 (T2) weeks, consisting of patient-reported outcomes, BMI, videofluoroscopy, swallowing capacity, and muscle strength measurements. Dysphagia significantly impacts quality of life, with impaired swallowing speed and bolus propulsion as main reported issues. Subjective dysphagia parameters, swallowing capacity, and pharyngeal residue clearance were reduced, but BMI was normal. Muscle and tongue strength were within normal ranges. All participants managed to use the SEA 2.0. Adherence was 95%. At T1, subjective swallowing parameters (MDADI and EAT-10) showed clinically relevant improvements. Objectively, CTAR and JOAR strength increased with 27.4 and 20.1 Newton, respectively. Also, swallowing capacity (from 2.4 g/s to 3.8 g/s) and pharyngeal residue clearance improved. At T2, results were slightly lower than at T1, but still better than at baseline. Dysphagia in laryngectomized patients affects quality of life, but swallowing can be improved with a six-week rehabilitation program using the novel SEA 2.0. Adherence was excellent and several subjective and objective swallowing parameters improved.

Abstract
Objective Laryngeal cancer (LC) is one of the most common squamous cell carcinomas of the head and neck in clinical practice, and its incidence has been increasing in recent years, but the prognosis of the patients is not favorable. Hence, it is critical to re-understand and deeply study the causes and mechanisms of LC and explore new effective treatment methods and strategies. In this study, we analyzed the effect of Dihydroartemisinin (DHA) on the pathological progression of LC through the periostin (POSTN)/Yes-associated protein (YAP)/interleukin (IL)-6 pathway, which can provide new clinical references and guidelines. Methods POSTN, YAP, and IL-6 levels in 18 pairs of fresh LC tissues and adjacent counterparts in our hospital were detected. Additionally, LC TU686 cell line was purchased for DHA treatment of various concentrations to detect changes in cell biological behavior. Finally, we built a tumor-bearing mouse model with C57BL/6 mice and intragastrically administrated DHA to the animals to observe the growth of living tumors and to measure POSTN, YAP, and IL-6 expression in tumor tissues. Results As indicated by PCR, Western blotting, and immunohistochemistry, POSTN, YAP, and IL-6 presented higher expression in LC tissues than in adjacent counterparts. In cell experiments, the cloning rate of LC cells decreased and the apoptosis rate increased after DHA intervention, with 160 μmol/L DHA contributing to the most significant effect on LC activity inhibition. Furthermore, DHA-intervened cells exhibited markedly reduced POSTN, YAP, and IL-6 levels. Finally, the tumorigenesis experiment in nude mice showed inhibited tumor growth after DHA administration. And consistently, the expressions of POSTN, YAP, and IL-6 in living tumors decreased. Conclusions DHA can inhibit POSTN/YAP/IL-6 transduction, accelerate LC cell apoptosis, and alleviate the malignant progression of LC.

Chemoradiotherapy vs radiotherapy for non-surgical locally advanced laryngeal squamous cell carcinoma patients: a propensity score-matched study and practical nomogram construction. Eur Arch Otorhinolaryngol 2024; 281:1449-1456. [PMID: 38158418 DOI: 10.1007/s00405-023-08360-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 11/14/2023] [Indexed: 01/03/2024]
Abstract
OBJECTIVE To compare the cancer-specific survival (CSS) among patients with locally advanced laryngeal squamous cell carcinoma (LSCC) receiving chemoradiotherapy (CRT) and radiotherapy (RT) treatment, as well as to establish a prognostic nomogram for survival prediction in patients receiving CRT. METHOD Using data from the Surveillance, Epidemiology, and End Results (SEER) database, patients with laryngeal cancer were identified between 2010 and 2015, with follow-up up to 2018. Propensity score matching (PSM) was performed to minimize disproportionate distributions of the potential confounding. Cox regression models were used to evaluate the CSS of two treatment groups. A prognostic nomogram for patients receiving CRT was then developed and evaluated. RESULTS Totally 1085 non-surgical patients with locally advanced LSCC were included in this study (median [IQR] age, 62 [55-69] years; 829 [76.41%] males), of which 913 receiving CRT and 172 receiving RT. After PSM, significantly improved CSS was observed in locally advanced LSCC patients receiving CRT when compared to RT (HR: 0.62 [95% CI 0.42-0.92]; P = 0.014). Then, in the group of 639 locally advanced LSCC patients receiving CRT, a prognostic nomogram based on age, tumor size, N category, and marital status were developed and validated, of which the predictive performance was superior to that of TNM staging system (7th edition). CONCLUSION CSS shows a statistically significant improvement in locally advanced LSCC patients who receipt of CRT when compared with RT. Furthermore, a prognostic nomogram for locally advanced LSCC patients receiving CRT was established, which shows a good calibration and identification accuracy.

Abstract
OBJECTIVE Laryngeal cancer, characterized by high recurrence rates and a lack of effective biomarkers, has been associated with cuproptosis, a regulated cell death process linked to cancer progression. In this study, we aimed to explore the roles of cuproptosis-related genes in laryngeal cancer and their potential as prognostic markers and therapeutic targets. METHODS We collected comprehensive data from The Cancer Genome Atlas and Gene Expression Omnibus databases, including gene expression profiles and clinical data of laryngeal cancer patients. Using clustering and gene analysis, we identified cuproptosis-related genes with prognostic significance. A risk model was constructed based on these genes, categorizing patients into high- and low-risk groups for outcome comparison. Univariate and multivariate analyses were conducted to identify independent prognostic factors, which were then incorporated into a nomogram. Gene Set Enrichment Analysis was employed to explore pathways distinguishing high- and low-risk groups. RESULTS Our risk model, based on four genes, including transmembrane 2, dishevelled binding antagonist of β-catenin 1, stathmin 2, and G protein-coupled receptor 173, revealed significant differences in patient outcomes between high- and low-risk groups. Independent prognostic factors were identified and integrated into a nomogram, providing a valuable tool for prognostic prediction. Gene Set Enrichment Analysis uncovered up-regulated pathways specifically associated with high-risk patient samples. CONCLUSION This study highlights the potential of cuproptosis-related genes as valuable prognostic markers and promising therapeutic targets in the context of laryngeal cancer. This research sheds light on new avenues for understanding and managing this challenging disease. LEVEL OF EVIDENCE Level 4.

The Diagnostic Value of CEUS in Assessing Non-Ossified Thyroid Cartilage Invasion in Patients with Laryngeal Squamous Cell Carcinoma. J Clin Med 2024; 13:891. [PMID: 38337585 PMCID: PMC10856113 DOI: 10.3390/jcm13030891] [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: 11/24/2023] [Revised: 01/24/2024] [Accepted: 01/30/2024] [Indexed: 02/12/2024] Open
Abstract
Background: Accurate assessment of thyroid cartilage invasion in squamous cell carcinoma (SCC) of the larynx remains a challenge in clinical practice. The aim of this study was to assess the diagnostic performance of contrast-enhanced ultrasound (CEUS), contrast-enhanced computed tomography (CECT), and magnetic resonance imaging (MRI) in the detection of non-ossified thyroid cartilage invasion in patients with SCC. Methods: CEUS, CECT, and MRI scans of 27 male patients with histologically proven SCC were evaluated and compared. A total of 31 cases were assessed via CEUS and CECT. The MR images of five patients and six cases were excluded (one patient had two suspected sites), leaving twenty-five cases for analysis via MRI. Results: CEUS showed the highest accuracy and specificity compared with CECT and MRI (87.1% vs. 64.5% and 76.0% as well as 84.0% vs. 64.0% and 72.7%, respectively). The sensitivity and negative predictive value of CEUS and MRI were the same (100%). CEUS yielded four false-positive findings. However, there were no statistically significant differences among the imaging modalities (p > 0.05). Conclusions: CEUS showed better diagnostic performance than CECT and MRI. Therefore, CEUS has the potential to accurately assess non-ossified thyroid cartilage invasion and guide appropriate treatment decisions, hopefully leading to improved patient outcomes.

Abstract
Background The management of laryngeal cancer involves balancing curative treatment with preserving essential functions. This study aimed to evaluate the clinical outcomes of helical tomotherapy, an advanced form of radiation therapy, as a primary treatment modality for laryngeal squamous cell carcinoma (LSCC). Methods A retrospective analysis of data obtained from a tertiary referral center was performed to assess treatment response rates, survival outcomes, disease control, and treatment-related adverse events. Results The study included 45 patients with LSCC treated with helical tomotherapy between May 2015 and September 2022. The 5-year overall survival (OS) rate and disease-free survival (DFS) rate were 89.2% and 71.1%, respectively. Local control and laryngeal preservation rates at 5 years were 79.7% and 84.7%, respectively. Subgroup analysis revealed higher DFS rates in early-stage patients (84.2%) compared to advanced-stage patients (58.9%). Conclusions The results indicate that helical tomotherapy offers effective tumor control and potential for laryngeal preservation in LSCC. Further prospective studies and longer follow-up are needed to validate these findings and optimize treatment strategies for LSCC patients.

A composition of ursolic acid derivatives from Ludwigia hyssopifolia induces apoptosis in throat cancer cells via the Akt/mTOR and mitochondrial signaling pathways and by modulating endoplasmic reticulum stress. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117351. [PMID: 37884218 DOI: 10.1016/j.jep.2023.117351] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 10/02/2023] [Accepted: 10/23/2023] [Indexed: 10/28/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ludwigia hyssopifolia (LH), an ethnopharmacological herb used in Guangxi Zhuang medicine, is known for its extensive therapeutic use in treating throat disorders. The anti-laryngeal-cancer benefits of the ethyl acetate and petroleum ether fractions of the ethanolic extracts of LH have been shown in our prior cell-based research. Nevertheless, the specific impacts and underlying processes by which LH combats throat cancer effects have not been fully understood. AIM OF THE STUDY This study involved the extraction of a composition containing two derivatives of ursolic acid from LH (LH-CUAD). The present study aimed to assess the anti-throat-cancer effects of these derivatives and the underlying mechanisms through in vitro and in vivo experiments. MATERIALS AND METHODS Solvent extraction, fractionation, chromatography, and semipreparative high-performance liquid chromatography were used for the extraction, purification, and analysis of LH-CUAD. The in vitro and in vivo anti-throat-cancer effects of LH-CUAD were investigated using the throat cancer cell lines Hep-2 and FaDu as well as Hep-2 tumor-bearing nude mice. RESULTS LH-CUAD significantly inhibited the proliferation and migration of throat cancer cells without any prominent toxicity. The Hoechst 33258 staining, Annexin V-FITC/PI double-staining assays, and flow cytometry confirmed that LH-CUAD could induce throat cancer cell death from early to late apoptosis in vitro. LH-CUAD exhibited significant antitumor activity and low toxicity in a xenograft model, and induced throat cancer cells apoptosis in vivo. The apoptotic effects of LH-CUAD therapy were validated using Western blotting, which demonstrated the activation of a caspase cascade response triggered by an imbalance between the endoplasmic reticulum and mitochondria. In addition, it was observed that LH-CUAD exhibited inhibitory effects on Akt and mTOR phosphorylation, hence promoting apoptosis. CONCLUSIONS LH-CUAD induces apoptosis in both in vivo and in vitro models of throat cancer. This effect is achieved by activating the mitochondrial pathway, inhibiting the Akt/mTOR pathway and initiating endoplasmic reticulum stress. The findings of this study suggest that LH-CUAD has the potential to offer a novel approach to the clinical management of throat cancer.

Abstract
Background: The mortality rates of laryngeal squamous cell carcinoma cancer (LSCC) have not significantly decreased in the last decades.Objectives: We primarily aimed to compare the predictive performance of DeepTables with the state-of-the-art machine learning (ML) algorithms (Voting ensemble, Stack ensemble, and XGBoost) to stratify patients with LSCC into chance of overall survival (OS). In addition, we complemented the developed model by providing interpretability using both global and local model-agnostic techniques.Methods: A total of 2792 patients in the Surveillance, Epidemiology, and End Results (SEER) database diagnosed with LSCC were reviewed. The global model-agnostic interpretability was examined using SHapley Additive exPlanations (SHAP) technique. Likewise, individual interpretation of the prediction was made using Local Interpretable Model Agnostic Explanations (LIME).Results: The state-of-the-art ML ensemble algorithms outperformed DeepTables. Specifically, the examined ensemble algorithms showed comparable weighted area under receiving curve of 76.9, 76.8, and 76.1 with an accuracy of 71.2%, 70.2%, and 71.8%, respectively. The global methods of interpretability (SHAP) demonstrated that the age of the patient at diagnosis, N-stage, T-stage, tumor grade, and marital status are among the prominent parameters.Conclusions: A ML model for OS prediction may serve as an ancillary tool for treatment planning of LSCC patients.

Abstract
Introduction Several techniques have been employed for defect reconstruction after total laryngectomy, among others sliding epiglottoplasty. As there is a paucity of data on sliding epiglottoplasty after total laryngectomy, this study aimed to present this reconstruction technique in detail with the retrospective analysis of the patients. Methods We retrospectively reviewed single-center medical records of patients who underwent pharyngeal reconstruction after total laryngectomy between 2007-2013, with a follow-up to 2020. The study included patients who had total laryngectomy performed followed by a primary closure or sliding epiglottoplasty. The patients were divided according to the pharyngeal reconstruction technique: sliding epiglottis (n = 38) and primary closure (n = 120). Results The baseline characteristics of patients, TNM stages, and previous treatment strategies did not differ significantly between the sliding epiglottis and primary closure group. The postoperative complication rates, including the pharyngocutaneous fistulae formation and strictures were comparable between the analyzed groups; however, a slightly higher incidence of pharyngocutaneus fistulae was noted within the patients after sliding epiglottoplasty. Overall 3-year survival of patients who underwent the epiglottoplasty and primary closure group were 73.7% vs. 57.5%, respectively. Conclusions Sliding epiglottoplasty is considered a safe reconstruction technique. Although slightly better outcomes were noted within the epiglottoplasty group, it is still considered inferior to the primary closure. This technique ought to be considered in meticulously selected patients in whom primary closure is not feasible, epiglottis with nearby structures is spared from disease, and when the distal flaps are less appropriate or contraindicated.

Abstract
OBJECTIVE Tracheoesophageal puncture with voice prosthesis (TEP) is considered the gold standard for voice rehabilitation after total laryngectomy; however, there is debate as to whether it should be inserted concurrently with removal of the larynx (primary TEP), or as a separate, additional procedure at a later date (secondary TEP). We utilized the National Surgical Quality Improvement Program Database (NSQIP) to compare postoperative complications, readmission rates, and reoperation rates among individuals who underwent total laryngectomy with or without concurrent TEP placement. METHODS We conducted a retrospective study using the American College of Surgeons National Surgical Quality Improvement Program database (ACS-NSQIP) from 2012 to 2019. Patients were categorized into primary and non-primary TEP groups using a variation of CPT codes for total laryngectomy, tracheoesophageal prosthesis, and type of reconstruction. Univariate analyses were performed and significance was determined at p < 0.05. RESULTS A total of 1974 patients who underwent total laryngectomy were identified from the database: 1505 (77.3 %) in the non-primary TEP group and 442 (22.7 %) in the primary TEP group. Patients in the non-primary TEP group were more likely to have an ASA class greater than or equal to three (91.2 % primary vs. 84.6 % non-primary, p < 0.001). Patients in the non-primary TEP group were also more likely to require intraoperative or postoperative blood transfusions within the first 72 h of surgery (20.5 % non-primary vs. 15.3 % primary, p = 0.016). Both groups had similar rates of wound breakdown and dehiscence. There remained no significant difference based on type of reconstruction. CONCLUSIONS This study suggests that patients receiving primary TEPs are not at a greater risk of developing wound complications such as pharyngocutaneous fistulas in the 30-day postoperative period. This remained true when patients were stratified by type of flap reconstruction. Patients in the non-primary TEP group were more likely to have an ASA category of 3 or greater, which may explain why they experienced higher rates of complications such as blood transfusions intra-operatively or post-operatively.

Abstract
Objective This study aimed to characterize the quality of laryngectomy-related patient education on YouTube and understand factors impacting video content quality. Study Design Cross-sectional cohort analysis. Setting Laryngectomy-related videos on YouTube. Methods YouTube was anonymously queried for various laryngectomy procedure search terms. Video quality was evaluated using the validated DISCERN instrument which assesses treatment-related information quality. Descriptive statistics were used to characterize our cohort. Univariate and multivariable linear regression were used to assess factors associated with increased DISCERN score. Significance was set at P < .05. Results Our 78-video cohort exhibited moderate levels of engagement, averaging 13,028.40 views (SD = 24,246.93), 69.79 likes (SD = 163.75), and 5.27 comments (SD = 18.81). Videos were most frequently uploaded to accounts belonging to physicians (43.59%) or health care groups (41.03%) and showcased operations (52.56%) or physician-led education (20.51%). Otolaryngologists were featured in most videos (85.90%), and most videos originated outside the United States (67.95%). Laryngectomy videos demonstrated poor reliability (mean = 2.35, SD = 0.77), quality of treatment information (mean = 1.92, SD = 0.86), and overall video quality (mean = 1.97, SD = 1.12). In multivariable linear regression, operative videos were associated with lower video quality relative to nonoperative videos (β = -1.63, 95% confidence interval [CI] = [-2.03 to -1.24], P < .001); the opposite was true for videos from accounts with higher subscriber counts (β = 0.02, 95% CI = [0.01-0.03], P = .005). Conclusion The quality and quantity of YouTube's laryngectomy educational content is limited. There is an acute need to increase the quantity and quality of online laryngectomy-related content to better support patients and caregivers as they cope with their diagnosis, prepare for, and recover from surgery.

Laryngeal squamous cell carcinoma (SCC) is one of the most common primary tumors of the head and neck region. Unfortunately, patients with laryngeal SCC tend to develop second primary tumors (SPTs), accounting for increased mortality. The lung is the predominant site of a second presentation, followed by the mucosa of the upper aerodigestive tract. In contrast, the thyroid gland rarely hosts an SPT. Our study describes the management and treatment of a 69-year-old female who presented with a rare combination of synchronous laryngeal and thyroid carcinomas. Supplementary Information The online version contains supplementary material available at 10.1007/s12070-023-03968-y.

Abstract
The assessment of volatile breath biomarkers has been targeted with a lot of interest by the scientific and medical communities during the past decades due to their suitability for an accurate, painless, non-invasive, and rapid diagnosis of health states and pathological conditions. This paper reviews the most relevant bibliographic sources aiming to gather the most pertinent volatile organic compounds (VOCs) already identified as putative cancer biomarkers. Here, a total of 265 VOCs and the respective bibliographic sources are addressed regarding their scientifically proven suitability to diagnose a total of six carcinogenic diseases, namely lung, breast, gastric, colorectal, prostate, and squamous cell (oesophageal and laryngeal) cancers. In addition, future trends in the identification of five other forms of cancer, such as bladder, liver, ovarian, pancreatic, and thyroid cancer, through perspective volatile breath biomarkers are equally presented and discussed. All the results already achieved in the detection, identification, and quantification of endogenous metabolites produced by all kinds of normal and abnormal processes in the human body denote a promising and auspicious future for this alternative diagnostic tool, whose future passes by the development and employment of newer and more accurate collection and analysis techniques, and the certification for utilisation in real clinical scenarios.

Concordance between head and neck MRI and histopathology in detecting laryngeal subsite invasion among patients with laryngeal cancer. Cancer Imaging 2023; 23:99. [PMID: 37858162 PMCID: PMC10585883 DOI: 10.1186/s40644-023-00618-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 10/07/2023] [Indexed: 10/21/2023] Open
Abstract
BACKGROUND Accuracy of head and neck MRI (HN-MRI) in predicting tumor invasion of laryngeal site/subsites in patients with laryngeal cancer prior to laryngectomy is poorly evaluated in the literature. Therefore, we aim to evaluate the diagnostic value of HN-MRI in accurate pre-operative estimation of tumor invasion to laryngeal subsites in patients with laryngeal cancer. METHODS Patients with laryngeal cancer who underwent HN-MRI for cancer staging and underwent total laryngectomy between 2008 and 2021 were included. Sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of HN-MRI in predicting tumor invasion of laryngeal subsites were calculated based on concordance between the HN-MRI and histopathological results. RESULTS One hundred and thirty-seven patients underwent total laryngectomy [primary: 82/137(60%), salvage 55/137(40%)]. The utilization of HN-MRI resulted in the downstaging of 16/137 (11.6%) patients and the upstaging of 8/137 (5.8%) patients. For the whole cohort, there was a significant discordance between HN-MRI and histopathology for T-category; out of 116 cT4a disease, 102(87.9%) were confirmed to have pT4a disease, and out of 17 cT3 disease, 9(52.9%) were confirmed to have pT3 disease, p < 0.001. The MRI overall diagnostic accuracy of predicting tumor invasion was 91%, 92%, 82%, 87%, 72%, 76%, 65% and 68% for base of tongue, arytenoid, vocal cord, posterior commissure, pre-epiglottic space, cricoid cartilage, inner thyroid cortex, and subglottis, respectively. CONCLUSIONS In patients with laryngeal cancer undergoing total laryngectomy, HN-MRI demonstrates promising accuracy in predicting tumor invasion of specific laryngeal subsites (e.g., base of tongue). Our findings showed the potential of HN-MRI as a valuable tool for pre-operative planning and treatment decision-making in this patient population.

Abstract
BACKGROUND Laryngeal cancer epidemiology has changed in recent years, with falling incidence observed internationally. Organ preservation therapies have revolutionised management, though some patients may be unsuitable and survival was noted to fall in the 2000s. This study examines trends in laryngeal cancer in Ireland. METHODS A retrospective cohort study of National Cancer Registry of Ireland data from 1994 to 2014. RESULTS From a cohort of 2651, glottic disease was most common (62%, n = 1646). Incidence rose to 3.43 cases/100,000/year for 2010-2014. 5-year disease-specific survival (DSS) was 60.6% and did not change significantly over time. Overall survival (OS) for T3 disease managed with primary radiotherapy was similar to primary surgery (HR 0.98, p = 0.9). DSS for T3 disease improved with primary radiotherapy (HR 0.72, p = 0.045). CONCLUSION Incidence of laryngeal cancer in Ireland rose despite international trends, while survival changed little. Radiotherapy improves DSS for T3 disease but does not improve OS, possibly secondary to poor organ function post-radiotherapy.

Abstract
PURPOSE The principal goal of treatment of laryngeal cancer is to eliminate a tumour while preserving laryngeal function with radio(chemo)therapy being the mainstay of treatment. The aim of this report is to present the influence of comorbidities and lifestyle factors on treatment outcomes in our cohort of patients. METHODS During the period 2009-2018, curative radio(chemo)therapy for laryngeal cancer was performed on 189 patients. RESULTS The median OS was 50.8 months, with a mean PFS of 96.5 months, mean LC of 101.4 months and a median follow-up of 38.1 months. Acute and late treatment toxicity grade 3-4 was observed in 39.2% patients and 10.1% patients, respectively. A significant effect on overall survival was confirmed for the baseline PS (performance status), severity of weight loss, baseline haemoglobin values, history of alcohol abuse, marital status and comorbidities according to the Charlson Comorbidity Index, as well as the ACE-27 and ASA scores. CONCLUSIONS In our cohort of patients treated with radio(chemo)therapy for laryngeal cancer, we found good therapeutic results and an acceptable side-effect profile. Statistically significant predictors of overall survival were the baseline PS, weight loss, anaemia, associated comorbidities, history of alcohol abuse and marital status.

Abstract
BACKGROUND The application of coagulation-related markers in laryngeal squamous cell carcinoma(LSCC) remains unclear. This study explored the prognostic role of coagulation markers in the progression and metastasis of LSCC. METHODS Coagulation markers of patients with LSCC receiving surgery in the Second Affiliated Hospital of Fujian Medical University in China, from January 2013 to May 2022 were retrospectively analyzed and compared with those of contemporary patients with benign laryngeal diseases. The relationship between clinicopathological features of LSCC and coagulation markers was analyzed with the chi-square and rank sum tests. The ROC curve analysis was utilized to evaluate the diagnostic efficacy of seven coagulation markers for LSCC and its different clinicopathological features, and to find the optimal cutoff value of each coagulation marker. RESULTS 303 patients with LSCC and 533 patients with benign laryngeal diseases were included in the present analysis. Compared to the control group, prothrombin time (PT) (p < 0.001), activated partial thromboplastin time (APTT) (p = 0.001), and Fib (p < 0.001) in patients with LSCC were significantly higher, while mean platelet volume (MPV) (p < 0.001) was significantly shorter. Significant increases were detected in PT (Z = 14.342, p = 0.002), Fib (Z = 25.985, p < 0.001), platelet count (PC) (Z = 12.768, p = 0.005), PCT (Z = 9.178, p = 0.027), MPV (F = 2.948, p = 0.033) in T4 stage. Fib had the highest prognostic value among the seven coagulation markers in different T stages (AUC = 0.676, p < 0.001), N stages (AUC = 0.717, p < 0.001), tumor stage (AUC = 0.665, p < 0.001), differentiation degree (AUC = 0.579, p = 0.022), and neurovascular invasion (AUC = 0.651, p = 0.007). Fib (Z = 25.832, p < 0.001), PC (Z = 23.842, p < 0.001), and PCT (Z = 20.15, p < 0.001) in N1 and N3 stages were significantly higher than in N0 stage. PT (Z = 12.174, p = 0.007), Fib (Z = 23.873, p < 0.001), PC (Z = 17.785, p < 0.001), and PCT (Z = 14.693, p = 0.002) were significantly higher in stage IV than in stage I and II. APTT (Z=-1.983, p = 0.047), Fib (Z=-2.68, p = 0.007), PC (Z=-2.723, p = 0.006), and PCT (Z=-2.592, p = 0.01) increased significantly when the tumor invaded neurovascular tissue. CONCLUSIONS Coagulation markers have the potential to act as biomarkers for predicting pathological features of LSCC. The high level of Fib was helpful for the diagnosis of LSCC and the detection of advanced LSCC. TRIAL REGISTRATION Not applicable.

Abstract
BACKGROUND The current treatment options for T1b glottic carcinoma often lead to poor treatment outcomes or voice quality. OBJECTIVES This study evaluates the therapeutic efficacy of horizontal middle partial laryngectomy with cricothyroidopexy (HMPL-CTP) for stage T1b glottic carcinoma. MATERIAL AND METHODS A retrospective analysis was conducted on 73 patients with T1b glottic carcinoma. The patients were categorized into three groups: Group A (n = 22) underwent transoral laser microsurgery (TLMS), Group B (n = 21) received frontolateral vertical partial laryngectomy (FVPL), and Group C (n = 30) underwent HMPL-CTP. The study analyzed the 5-year overall survival rate (OS), recurrence rate, phonatory status, and incidence of laryngeal stenosis. RESULTS Voice quality scores varied significantly in the three groups, while the 5-year OS were similar. The local recurrence rate is higher in Group A than in the other two groups. The laryngeal stenosis rate in Group B is higher than in Groups A and C. Adhesions in the anterior commissure were observed in 18 cases in Group A and nine cases in Group C. CONCLUSIONS AND SIGNIFICANCE HMPL-CTP demonstrates efficacy as a treatment for stage T1b glottic carcinoma, offering favorable preservation of laryngeal function and minimal complications.

Abstract
Background Radiotherapy (RT) is an appropriate treatment option for early-stage glottic cancer (ESGC) that achieves high local control and preserves voice quality. However, the optimal radiation treatment schedule remains unknown. We present our institution's 14-year experience in treating ESGC with definitive radiotherapy between 2005 and 2019 inclusively. Materials and methods We reviewed the medical records of 104 patients; 63 (60.5%) were treated with conventional fractionation (CF), and 41 (39.5%) were treated with hypofractionated radiotherapy (HF). The clinical T-stage was T1a in 50 patients (48%), T1b in 27 (26%), and T2 in 27 (26%). Age, gender, anterior commissure involvement, stage, radiotherapy technique, radiation fraction size, and overall treatment time (OTT) were analyzed as prognostic factors. The survival outcomes, local regional control (LRC), and laryngeal preservation rate were evaluated. Results The 5-year overall survival (OS) and LCR were 83.3% and 78%, respectively. On univariate analysis, treatment with CF (p = 0.02), prolonged OTT > 49 days in CF and > 40 days in HF (p = 0.04), and RT total dose < 66 Gy (p = 0.03) were associated with poor LRC. Multivariate analysis showed a non-significant association with LRC (all p > 0.05). The 5-year OS rate in the CF and HF-treated patients was 84.9% and 72.1%, respectively (p = 0.99), and in patients who had T1a, T1b, and T2 disease, were 78.2%, 96.0%, and 82.1%, respectively (p = 0.43). All patients and tumor variables showed no statistically significant association with OS. Only low-grade acute toxicity was observed. Conclusion Non-inferiority results supported the HF schedule to ESGC, including high local disease control and decreased overall treatment time. Our study supports its efficacy in the primary care of ESGC with manageable side effects.

Abstract
Given the global increase in the incidence of head and neck cancers over the last decade, the use of chemoradiation has also increased. It is well known that chemotherapy/radiation are established standard therapies in head and neck cancers, especially in patients who are not candidates for surgery. Despite this increase in chemoradiation therapies in head and neck cancers, there is a lack of established guidelines on the surveillance and screening of these patients for long-term complications. We present an interesting case of acute left eye blindness in a veteran patient with a history of laryngeal cancer status post chemoradiation and in the setting of a left ventricular (LV) thrombus on anticoagulation resulting in a diagnostic challenge determining the etiology. This case emphasizes the need for thorough patient-centered annual evaluation, thus providing an opportunity for early noninvasive or minimally invasive intervention.

Abstract
PURPOSE We conducted an outcome analysis on surgically treated laryngeal squamous cell carcinoma (LSCC) patients. METHODS A multicenter retrospective study with 352 patients was analyzed. A new nomogram that incorporates age, T- and N-classification, and treatment was created. RESULTS Recurrence was observed in 65 (18.5%) patients after a mean time of 16.5 months. After 60 months, 91 (25.9%) of patients developed secondary primary tumors (SPT), most commonly in the lungs (n = 29; 8.2%) followed by other head and neck cancers (n = 21; 6.0%). Notably, the mean time to occurrence of secondary head and neck cancers was twice that of lung cancer (101.1 vs. 47.5 months). CONCLUSION Recurrent disease is less common in LSCC patients and appears much earlier than SPT. Because one in every four laryngeal cancer patients develops SPTs within 5-10 years, long-term care and follow-up, including imaging studies, are highly recommended. The nomogram was useful for estimating survival.

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.

Abstract
The prognosis of laryngeal cancer is affected by clinicopathological factors. Because of that, an effective prognostic marker is very valuable in managing the clinical process. The p53 evaluation method, used in the literature recently, was used for the first time in laryngeal cancer. We evaluated PTEN with 2 methods with the highest significance in the literature on laryngeal cancer. All demographic and histopathological data from 140 laryngeal cancers were compared with p53 and PTEN expressions and survival. p53 staining patterns were classified as wild and mutant. PTEN expression was evaluated according to the staining intensity named PTEN1 and according to the proportion of stained cells named PTEN2. In the series, 93.6% were males, and the mean survival was 38 months. 69.3% of cases were p53 mutants. PTEN loss was found to be 85.7% and 57.9%, respectively. Tumor size and thyroid cartilage invasion for PTEN1 and age for p53 were identified as independent predictive factors (P < .01). Advanced age, total laryngectomy, and extranodal spread were independent poor prognostic factors for overall survival and the presence of subglottic involvement, perineural invasion, and extranodal spread were for disease-free survival (P < .01). This is the first study in which the new p53 classification was used in laryngeal cancer, and will contribute significantly to the literature with differences from the previous evaluation patterns. Evaluation of PTEN based on staining intensity is more appropriate compared to the percentage of stained cells.

Abstract
Laryngeal cancer is a usual malignant tumor of the head and neck. The role and mechanism of deubiquitinase USP21 in laryngeal cancer are still unclear. We aimed to explore whether USP21 affected laryngeal cancer progress through deubiquitinating AURKA. USP21 and AURKA levels were evaluated by qRT-PCR and Western blot. Kaplan-Meier analysis was conducted by survival package. MTT was performed to detect cell proliferation. The wound healing assay was applied to evaluate cell migration. Transwell was used to measure cell invasion. Co-IP and GST-pull down determined the interaction between USP21 and AURKA. In addition, AURKA ubiquitination levels were analyzed. USP21 was signally elevated in laryngeal cancer tissues and cells. USP21 level in clinical stages III-IV was higher than that in clinical stages I-II, and high levels of USP21 were highly correlated with poor prognosis in laryngeal cancer. USP21 inhibition suppressed AMC-HN-8 and TU686 cell proliferation, migration and invasion. Co-IP and GST-pull down confirmed the interaction between USP21 and AURKA. Knockdown of USP21 markedly increased the ubiquitination level of AURKA, and USP21 restored AURKA activity through deubiquitination. In addition, overexpression of AURKA reversed the effects of USP21 knockdown on cell growth, migration, and invasion. USP21 stabilized AURKA through deubiquitination to promote laryngeal cancer progression.

Abstract
BackgroundFor the surgical treatment of early-stage laryngeal cancer, the use of transoral laser microsurgery (TLM) has emerged as the gold standard. However, this procedure requires a straight line of sight to the operating field. Therefore, the patient's neck needs to be brought into a hyperextended position. In a considerable number of patients, this is not possible due to anomalies in the cervical spine anatomy or soft tissue scarring, e.g., after radiation. In these cases, adequate visualization of relevant laryngeal structures cannot be ensured using a conventional rigid operating laryngoscope, which may negatively affect the outcome of these patients.MethodsWe present a system based on a 3D-printed prototype of a curved laryngoscope with three integrated working channels (sMAC). The curved profile of the sMAC-laryngoscope is specifically adapted to the nonlinear anatomy of the upper airway structures. The central working channel provides access for flexible video endoscope imaging of the operating field while the two remaining channels provide access for flexible instrumentation. In a user study (n = 11), visualization and reachability of relevant laryngeal landmarks as well as the feasibility of basic surgical procedures with the proposed system were examined in a patient simulator. In a second setup, the system was evaluated for its applicability in a human body donor.ResultsAll participants of the user study were able to visualize, reach and manipulate the relevant laryngeal landmarks. Reaching those took significantly less time in the second attempt compared to the first one (27.5 s ± 5.2 s vs. 39.7 s ± 16.5 s, p = 0.008) indicating a significant learning curve for handling the system. Instrument changes were performed quickly and reliably by all participants (10.9 s ± 1.7 s). All participants were able to bring the bimanual instruments into position for a vocal fold incision. Relevant laryngeal landmarks could be visualized and reached in the human body donor setup.ConclusionPossibly, the proposed system may develop into an alternative treatment option for patients with early-stage laryngeal cancer and restricted mobility of the cervical spine in the future. Further improvements of the system could include finer end effectors and a flexible instrument with a laser cutting tool.

Abstract
Laryngeal cancer (LC) is a rare and challenging clinical problem. Our aim was to investigate the mechanism of salt-like transcription factor 4 (SALL4) in LC. LC tissue and paracancerous tissue were collected. Relative mRNA or protein levels were measured by quantitative real-time polymerase chain reaction or Western blot. MTT, wound healing, and transwell assay were performed to evaluate cell proliferation, migration and invasion. The binding relationship between SALL4 and USP21 promoter was verified by dual-luciferase assay and ChIP. Co-IP and glutathione-S-transferase (GST)-pull down were performed to measure the protein interaction between USP21 and YY1. Additionally, YY1 ubiquitination level was analyzed. It was found that SALL4 mRNA and SALL4 protein levels were elevated in LC clinical tissues and various LC cells. Knockdown of SALL4 inhibited epithelial-mesenchymal transition (EMT) of LC cells. USP21 was transcriptionally activated by SALL4. Co-IP and GST-pull down confirmed USP21 interacted with YY1. USP21 protected YY1 from degradation through deubiquitination. Furthermore, overexpression of USP21 reversed the effect of knockdown of SALL4 on YY1 and EMT in LC cells. In general, SALL4 facilitated EMT of LC cells through modulating USP21/YY1 axis.

Abstract
Herein, we report the first study to create a three-dimensional (3D) bioprinted artificial larynx for whole-laryngeal replacement. Our 3D bio-printed larynx was generated using extrusion-based 3D bioprinter with rabbit's chondrocyte-laden gelatin methacryloyl (GelMA)/glycidyl-methacrylated hyaluronic acid (GMHA) hybrid bioink. We used a polycaprolactone (PCL) outer framework incorporated with pores to achieve the structural strength of printed constructs, as well as to provide a suitable microenvironment to support printed cells. Notably, we established a novel fluidics supply (FS) system that simultaneously supplies basal medium together with a 3D bioprinting process, thereby improving cell survival during the printing process. Our results showed that the FS system enhanced post-printing cell viability, which enabled the generation of a large-scale cell-laden artificial laryngeal framework. Additionally, the incorporation of the PCL outer framework with pores and inner hydrogel provides structural stability and sufficient nutrient/oxygen transport. An animal study confirmed that the transplanted 3D bio-larynx successfully maintained the airway. With further development, our new strategy holds great potential for fabricating human-scale larynxes with in vivo-like biological functions for laryngectomy patients.

Abstract
Mucoepidermoid carcinoma is a common malignant neoplasm of the salivary glands. While quite common in the oral cavity, it is rare in the larynx. A middle-aged male patient presented to the otolaryngology clinic of our institution with the chief complaint of hoarseness. A supraglottic subepithelial mass was detected on the left laryngeal ventricle after a comprehensive clinical examination. Eventually, the diagnosis was established with a biopsy after a direct laryngoscopy. The multidisciplinary team of our institution suggested total laryngectomy without adjuvant modalities. An uneventful procedure followed and the patient remains free of disease and up to date. Mucoepidermoid tumors of the larynx are rare and surgical treatment is strongly indicated as the treatment of choice.

[PMID: 36539363 PMCID: PMC9760473 DOI: 10.1097/cad.0000000000001313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Accepted: 03/23/2022] [Indexed: 12/24/2022]
Abstract
Laryngeal carcinoma represents one of the most common types of tumor of the respiratory tract. The aim of the present study was to evaluate the functions of myosin-binding protein C1 (MYBPC1) in the progression of laryngeal carcinoma and to unravel the potential underlying molecular mechanism(s). Significantly differentially expressed mRNAs and miRNAs were analyzed, and potential genes were verified using clinically recruited patients with laryngeal carcinoma. The human laryngeal carcinoma cell lines TU686, TU212 and AMC-HN-8, as well as the control nasopharyngeal epithelial cell line NP69, were selected for the functional analysis of MYBPC1. The interaction between MYBPC1 and miR-451a was also explored in depth. The functions of MYBPC1 in the laryngeal carcinoma cell lines were examined using colony formation assay, cell proliferation and invasion assays, and via measuring the extent of apoptosis. The intracellular function of MYBPC1 was subsequently confirmed by constructing an in vivo xenograft model through the subcutaneous injection of laryngeal carcinoma cells into 4-week-old male nude mice. Compared with normal tissue, MYBPC1 was found to be the most significantly downregulated gene, whereas activating transcription factor-2 (ATF-2) was the most significantly upregulated one. At the same time, miR-451a was found to be the most significantly downregulated miRNA in laryngeal squamous cell carcinoma tissues. According to the WHO classification system, we found that the level of MYBPC1 was significantly decreased in grade IV tissues compared with grade II and grade III tissues, a finding that was consistent with the observed activity of miR-451a. MiR-451a was found to cause a marked enhancement of the activity of MYBPC1 in TU212 cells, which in turn was attenuated by ATF overexpression, suggesting that miR-451a could indirectly modulate the function of MYBPC1 through the ATF2-dependent signaling axis. MYBPC1 suppressed the invasion of cells induced by ATF2 in laryngeal carcinoma cells. Moreover, subcutaneous injection of MYBPC1 to construct an in vivo xenograft mouse model enabled rescue of the mice from laryngeal carcinoma formation. Taken together, the results of the present study have shown that MYBPC1 fulfills a pivotal role in laryngeal carcinoma formation, and these findings may provide both a new avenue for research planning and a potential therapeutic target for laryngeal carcinoma.

Abstract
AbstractWe constructed a prognostic score (PS) model to predict the recurrence risk in patients previously diagnosed with laryngeal cancer (LC). Here the training dataset, consisting of 82 LC samples, was downloaded from The Cancer Genome Atlas (TCGA). The PS model then divided the LC samples into high- and low-risk groups, which predicted well the survival time of LC in three datasets (TCGA dataset: AUC = 0.899; GSE27020: AUC = 0.719; and GSE25727: AUC = 0.662). Therefore, the PS model based on the 10 genes and its nomogram is proposed to help predict the recurrence risk in patients with LC.

Abstract
BACKGROUND Immune checkpoint inhibitors are promising tools in combating several cancers, including head and neck squamous cell carcinoma (HNSCC). However, a substantial portion of HNSCC patients do not respond to PD-L1 antibody. Here we describe a photodynamic therapeutic (PDT) approach to enhance anti-tumor effects of the anti-PD-L1 antibody. METHODS Phototoxicity of PDT was confirmed using fluorescence microscopy, Cell Counting Kit-8 (CCK-8), Enzyme Linked Immunosorbent Assay (ELISA) and flow cytometry analyses. Phenotypic and functional maturation of immature DCs (imDCs) induced by PDT were measured using flow cytometry and ELISA. A mouse model was established using the HNSCC line, SCC7, and was used to evaluate therapeutic effects of PDT-DC vaccine in facilitating anti-tumor immunity of PD-L1 antibody. RESULTS Immunogenic cell death (ICD) of SCC7 cells was induced by PDT with 0.5 µM of m-THPC and the 5 J/cm2 of light dose. ICD of SCC7 cells stimulated imDCs maturation. In vivo assays suggested that PDT-DC vaccine and anti-PD-L1 mAb synergistically induced anti-tumor immunity and suppressed tumor progression. CONCLUSION PDT-DC vaccine enhances therapeutic effects of PD-L1 antibody, which might provide a novel approach for HNSCC immunotherapy.

Abstract
Laryngeal cancer is one of the highest incidence, most prevalently diagnosed head and neck cancers, making it critically necessary to probe effective targets for laryngeal cancer treatment. Here, real-time quantitative reverse transcription PCR (qRT-PCR) and western blot analysis were used to detect gene expression levels in laryngeal cancer cell lines. Fluorescence in situ hybridization (FISH) and subcellular fractionation assays were used to detect the subcellular location. Functional assays encompassing Cell Counting Kit-8 (CCK-8), 5-ethynyl-2'-deoxyuridine (EdU), transwell and wound healing assays were performed to examine the effects of target genes on cell proliferation and migration in laryngeal cancer. The in vivo effects were proved by animal experiments. RNA-binding protein immunoprecipitation (RIP), RNA pulldown and luciferase reporter assays were used to investigate the underlying regulatory mechanisms. The results showed that KIF26B antisense RNA 1 (KIF26B-AS1) propels cell proliferation and migration in laryngeal cancer and regulates the toll-like receptor 4 (TLR4) signaling pathway. KIF26B-AS1 also recruits FUS to stabilize TLR4 mRNA, consequently activating the TLR4 signaling pathway. Furthermore, KIF26B-AS1 plays an oncogenic role in laryngeal cancer via upregulating TLR4 expression as well as the FUS/TLR4 pathway axis, findings which offer novel insight for targeted therapies in the treatment of laryngeal cancer patients.

Abstract
In this study, the anti-cancer and anti-inflammatory activities of PS14, a short peptide derived from the cellulase binding domain of pathogenic fungus, Aphanomyces invadans, have been evaluated, in vitro and in vivo. Bioinformatics analysis of PS14 revealed the physicochemical properties and the web-based predictions, which indicate that PS14 is non-toxic, and it has the potential to elicit anti-cancer and anti-inflammatory activities. These in silico results were experimentally validated through in vitro (L6 or Hep-2 cells) and in vivo (zebrafish embryo or larvae) models. Experimental results showed that PS14 is non-toxic in L6 cells and the zebrafish embryo, and it elicits an antitumor effect Hep-2 cells and zebrafish embryos. Anticancer activity assays, in terms of MTT, trypan blue and LDH assays, showed a dose-dependent inhibitory effect on cell proliferation. Moreover, in the epithelial cancer cells and zebrafish embryos, the peptide challenge (i) caused significant changes in the cytomorphology and induced apoptosis; (ii) triggered ROS generation; and (iii) showed a significant up-regulation of anti-cancer genes including BAX, Caspase 3, Caspase 9 and down-regulation of Bcl-2, in vitro. The anti-inflammatory activity of PS14 was observed in the cell-free in vitro assays for the inhibition of proteinase and lipoxygenase, and heat-induced hemolysis and hypotonicity-induced hemolysis. Together, this study has identified that PS14 has anti-cancer and anti-inflammatory activities, while being non-toxic, in vitro and in vivo. Future experiments can focus on the clinical or pharmacodynamics aspects of PS14.

Abstract
BACKGROUND To investigate the prognostic value of pre-treatment Controlling Nutritional Status (CONUT) score in laryngeal cancer. METHODS Preoperative CONUT score was retrospectively calculated in 154 laryngeal cancer patients who underwent curative resection in our hospital from 2013 to 2016. The associations of CONUT with clinicopathological factors and survival were evaluated. The efficacy of CONUT score to predict prognosis was evaluated. RESULTS The CONUT score was associated with body mass index (p = 0.033), neutrophil (p = 0.011), tumor size (p = 0.017), pTNM stage (p = 0.001), adjuvant radiotherapy (p < 0.001), negative pathologic factors (p < 0.001), and larynx preservation (p < 0.001). Patients with a higher CONUT score had worse overall survival (hazard ratio: 1.94, 95% confidence interval [CI]: 1.13-3.72, p = 0.039) and disease-free survival (hazard ratio: 2.16, 95% CI: 1.19-3.90, p = 0.011). The area under the curve of CONUT score (0.728) was higher than Preoperative Nutritional Index (0.72), platelet-to-lymphocyte ratio (0.675), and neutrophil-to-lymphocyte ratio (0.687). CONCLUSION The CONUT score can be useful for predicting survival in laryngeal cancer patients after curative resection.

Abstract
PURPOSE The main objective of this study was to analyze the prognostic role of the initial grade of dysplasia on the progression to SCC. STUDY DESIGN Retrospective cohort. METHODS This study was performed in the Otorhinolaryngology Department of a tertiary hospital center from January 2010 to December 2020. Every patient submitted to a microlaryngoscopy during this period with a histology of dysplasia on the first biopsy was included. RESULTS A total of 112 patients were included and median follow-up was 24 months (range 1-120 months). Mean age at diagnosis was 59.71 (+/- 12.03) and 88 patients were male (78.6%). Initial grade of dysplasia was mild on 60 patients (53.6%), moderate on 24 (21.4%), severe on 18 (16.1%), and carcinoma in situ in 10 (8.9%). Overall, 25 patients (21.4%) developed invasive squamous cell carcinoma (SCC) and 15 (13.4%) died during follow-up. On an adjusted 5 year's progression free survival analysis, considering gender, age, dysplasia grade, tobacco and alcohol consumption, the initial grade of dysplasia was the only factor significantly associated with progression to carcinoma (P = .047). When compared to mild dysplasia, moderate dysplasia had a Hazard Ratio (HR) of 0.81 (95%CI 0.21-3.22); severe dysplasia had a HR of 1.76 (95%CI 0.59-5.30) and carcinoma in situ had a HR of 4.25 (95%CI 1.44-12.59). CONCLUSION The initial dysplasia grade seems to be the most important prognostic factor regarding progression to SCC in patients with premalignant vocal fold disease.

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
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.

Abstract
Background: Early diagnosis of laryngeal lesions is necessary to begin treatment of patients as soon as possible to preserve optimal organ functions. Imaging examinations are often aided by artificial intelligence (AI) to improve quality and facilitate appropriate diagnosis. The aim of this study is to investigate diagnostic utility of AI in laryngeal endoscopy. Methods: Five databases were searched for studies implementing artificial intelligence (AI) enhanced models assessing images of laryngeal lesions taken during laryngeal endoscopy. Outcomes were analyzed in terms of accuracy, sensitivity, and specificity. Results: All 11 studies included presented an overall low risk of bias. The overall accuracy of AI models was very high (from 0.806 to 0.997). The accuracy was significantly higher in studies using a larger database. The pooled sensitivity and specificity for identification of healthy laryngeal tissue were 0.91 and 0.97, respectively. The same values for differentiation between benign and malignant lesions were 0.91 and 0.94, respectively. The comparison of the effectiveness of AI models assessing narrow band imaging and white light endoscopy images revealed no statistically significant differences (p = 0.409 and 0.914). Conclusion: In assessing images of laryngeal lesions, AI demonstrates extraordinarily high accuracy, sensitivity, and specificity.

Mechanism of miR-340-5p in laryngeal cancer cell proliferation and invasion through the lncRNA NEAT1/MMP11 axis. Pathol Res Pract 2022; 236:153912. [PMID: 35700579 DOI: 10.1016/j.prp.2022.153912] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2021] [Revised: 04/07/2022] [Accepted: 04/22/2022] [Indexed: 02/06/2023]
Abstract
OBJECTIVES Laryngeal cancer (LC), with a relatively rare diagnosis, is a primary malignancy originating from laryngeal mucosa. This study investigated the mechanisms of microRNA (miR)- 340-5p in LC cell proliferation and invasion. METHODS The expression patterns of miR-340-5p, long non-coding RNA (lncRNA) nuclear paraspeckle assembly transcript 1 (NEAT1), and matrix metallopeptidase 11 (MMP11) in LC cells, tissues, and para-carcinoma tissues, and human bronchial epithelial cells (HBEC) were examined via RT-qPCR. The effects of elevating or silencing miR-340-5p on LC cell proliferation and invasion were examined. The subcellular localization of lncRNA NEAT1 was determined. The binding relations among miR-340-5p, lncRNA NEAT1, and MMP11 were verified. Functional rescue experiments were designed to verify the functions of lncRNA NEAT1 and MMP11 on LC cell proliferation and invasion. Nude-mouse tumor models were established to assess the role of miR-340-5p in LC in vivo. RESULTS miR-340-5p was under-expressed in LC, and miR-340-5p overexpression repressed LC cell proliferation and invasion. Mechanically, miR-340-5p decreased lncRNA NEAT1 stability via directly binding to lncRNA NEAT1 and thus declined lncRNA NEAT1 expression in LC cells, while lncRNA NEAT1 accelerated MMP11 transcription via binding to heat shock factor 1 (HSF1). Overexpression of lncRNA NEAT1 or MMP11 reversed the repression of miR-340-5p overexpression on LC cell proliferation and invasion. In vivo, miR-340-5p overexpression repressed the tumor growth. CONCLUSION miR-340-5p overexpression reduced lncRNA NEAT1 stability via binding to lncRNA NEAT1, which declined lncRNA NEAT1 expression and reduced the binding of lncRNA NEAT1 to HSF1 to further inhibit MMP11 transcription, thus repressing LC cell proliferation and invasion.
