Abstract
The field cancerization theory is an important paradigm in head and neck carcinoma as its oncological repercussions affect treatment outcomes in diverse ways. The aim of this study is to assess the possible interconnection between peritumor mucosa and the process of tumor neoangiogenesis. Sixty patients with advanced laryngeal carcinoma were enrolled in this study. The majority of patients express a canonical HIF-upregulated proangiogenic signature with almost complete predominancy of HIF-1α overexpression and normal expression levels of the HIF-2α isoform. Remarkably, more than 60% of the whole cohort also exhibited an HIF-upregulated proangiogenic signature in the peritumoral benign mucosa. Additionally, the latter subgroup had a distinctly shifted phenotype towards HIF-2α upregulation compared to the one in tumor tissue, i.e., a tendency towards an HIF switch is observed in contrast to the dominated by HIF-1α tumor phenotype. ETS-1 displays stable and identical significant overexpression in both the proangiogenic phenotypes present in tumor and peritumoral mucosa. In the current study, we report for the first time the existence of an abnormal proangiogenic expression profile present in the peritumoral mucosa in advanced laryngeal carcinoma when compared to paired distant laryngeal mucosa. Moreover, we describe a specific phenotype of this proangiogenic signature that is significantly different from the one present in tumor tissue as we delineate both phenotypes, quantitively and qualitatively. This finding is cancer heterogeneity, per se, which extends beyond the "classical" borders of the malignancy, and it is proof of a strong interconnection between field cancerization and one of the classical hallmarks of cancer-the process of tumor neoangiogenesis.

Abstract
Key Clinical Message Laryngeal neuroendocrine carcinomas are the most common non-squamous neoplasm of the larynx. Due to the rarity of the tumor, pathological diagnosis should be confirmed by immunohistochemistry. Abstract Laryngeal neuroendocrine carcinomas (LNECs) are a rare cancer of the head and neck. Few case reports of poorly differentiated neuroendocrine carcinoma originating in the subglottic larynx exist within the literature. In this case, we discuss a 57-year-old patient with a history of four-month hoarseness with a newly diagnosed of poorly differentiated neuroendocrine carcinoma in the subglottic larynx. Treatment and prognosis of the various NEC groups differ, so precise identification requires consideration of the microscopic findings and immunostaining analysis. immunohistochemistry staining demonstrated positive result for cytokeratin 7, synaptophysin, chromogranin, CD 56, with the Ki-67 index of45%. Although surgery is usually the treatment for all tumor types, chemo radiotherapy is recommended for poorly differentiated NECs because surgery is ineffective.

Abstract
OBJECTIVE Numerous methods and materials are available for vertical partial laryngectomy. In this study, the reparative effects of the platysma myocutaneous flap (PMF) and ribbon myocutaneous flap (RMF) on the postoperative voice quality of patients were compared to provide a reference for selecting a method conducive to improving postoperative voice quality. METHODS A retrospective analysis was performed on patients with unilateral T2-3 glottic carcinoma. Following vertical partial laryngectomy, the defect was repaired with a PMF or simple RMF. Twelve months after surgery, voice quality was assessed according to voice acoustics, aerodynamics, and subjective perceptual evaluation, and glottic morphology was recorded using a laryngeal stroboscopy. RESULTS A total of 70 patients were identified, including 54 in the PMF group and 16 in the RMF group. The PMF group was superior to the RMF group in terms of voice quality assessed by voice acoustics, aerodynamics, and subjective perceptual evaluation. In the PMF group, 72.2% of patients performed phonation with their vocal cords, and approximately 27.8% of patients were affected by supraglottic compression. In the RMF group, 81.3% of patients were affected by supraglottic compression. No significant difference was found in the 5-year survival rate between the two groups. CONCLUSION For defect repair following vertical partial laryngectomy, a PMF can allow better postoperative voice quality to be achieved than an RMF because a PMF can provide more tissue (including strap muscle under the flap) for padding, which enables the glottic portion corresponding to the vocal cord to close well.

Abstract
Subglottic masses is very rare. The clinical data of five cases of subglottic mass in our hospital from 2017 to 2022 were summarized, and their clinical manifestations, auxiliary examination findings, treatment plan and pathological features were analyzed. Among the 5 patients, 1 case was subglottic pleomorphic adenoma, 1 case was subglottic granuloma, 1 case was subglottic breast cancer metastasis, 1 case was subglottic primary adenoid cystic carcinoma, and 1 case was immunoglobulin G4-related disease. No recurrence was observed in the patients so far. Subglottic mass is easy to be missed. Therefore, when the lesion is suspected in this area, the examination of ear, nose and throat should be carried out systematically to detect the lesion early and improve the prognosis.

Abstract
Folate receptor 1 (FOLR1) is overexpressed in numerous epithelial malignancies; however, its role in laryngeal squamous cell carcinoma (LSCC) remains unclear. In the present study, we demonstrated that FOLR1 messenger RNA and protein expression levels were higher in LSCC tissues than in the adjacent normal tissues. Additionally, FOLR1 promoted the proliferation and migration of LSCC cells, whereas small interfering RNA-mediated knockdown of β-catenin abolished these effects. Moreover, FOLR1 stabilizes β-catenin by inhibiting its ubiquitination and degradation. Furthermore, blocking the interaction between epidermal growth factor receptor (EGFR) and the EGFR/AKT/glycogen synthase (GSK)3β signaling axis both abolished FOLR1's effects on the expression and nuclear aggregation of β-catenin. In summary, our work reveals a novel mode in which FOLR1 promotes the proliferation and migration of LSCC by enhancing the stability and nuclear translocation of β-catenin through the EGFR/AKT/GSK3β axis.

Abstract
Background Laryngeal cancer was one of the most common malignancies of the head in those years. It has become one of the most common causes of death due to its high recurrence rate and high metastasis rate. It was well known that platelets, especially activated platelets, promote the proliferation, division, and invasion of tumor cells. Activated platelets promote cancer progression and metastasis. However, the prognostic value of platelet aggregation function in laryngeal cancer remains poorly understood. The purpose of this study was to investigate the predictive significance of platelet aggregation function in laryngeal cancer. Materials and Methods Between January 2015 and December 2016, we conducted a retrospective analysis of 203 patients who were diagnosed with laryngeal cancer consecutively. The patients were stratified by platelet aggregation function into two groups: low "adenosine diphosphate induced light transmittance aggregometry (ADP-induced LTA) ≤15.1" and high (ADP-induced LTA >15.1). Pathological tissues from different parts of the operation were collected and the pathologist determined the pathological type. We assessed the prognostic significance of platelet aggregation function using Kaplan-Meier curves and Cox regression. Results The low cohort had a significantly higher lymphocyte count than the high cohort. Compared with the high cohort, the low cohort had significantly lower levels of platelet-to-lymphocyte ratio (PLR), ADP-induced LTA, and Interleukins (IL)-6. The ADP-induced LTA (hazard ratio, 1.212; P <0.001) was independently related with 5-year overall survival rate. Conclusion Patients with ADP-induced LTA >15.1 experience poor outcomes. Platelet aggregation function, when elevated, could be a new prognostic indicator for laryngeal cancer.

Abstract
BACKGROUND Pretherapeutic discussion in the head and neck tumor board (HNT) has been mandatory at the University Medical Center Freiburg since 01/2015, and it is intended to contribute to a survival benefit through interdisciplinary decision making. Prior to 2015, an optional HNT existed in which mainly advanced tumor stages were discussed. The aim of this study was to determine the effect of a pretherapeutic HNT on treatment and survival in laryngeal cancer. METHODS A retrospective data analysis of 412 laryngeal carcinoma patients treated at the Head and Neck Cancer Center of the University Medical Center Freiburg between 01/2010 and 12/2020 was conducted. Differences regarding TNM status, UICC classification, tumor localization, gender and age at initial diagnosis, recurrence, secondary tumors, therapy, 5-year survival, and 5-year recurrence-free survival (5YSR/5Y-RFS) were assessed for therapy initiation with or without a pretherapeutic HNT. RESULTS In total, 314 patients underwent a pretherapeutic HNT, and 98 received therapy initiation without an HNT. The HNT group showed significantly more advanced T stages and UICC classifications (p < 0.001; p = 0.003) and more frequent primary chemo/radiotherapy (p < 0.001). There was no significant difference regarding 5YSR (43 vs. 47 months, p = 0.96) or 5Y-RFS (48 vs. 52 months, p = 0.16). The time between initial diagnosis and therapy initiation was significantly longer when an HNT was performed (38 vs. 20 days, p = 0.008). CONCLUSIONS The HNT group showed significantly more advanced tumor stages, suggesting that even before it became mandatory, it was frequently used for interdisciplinary case discussion in more complex cases. Due to the small number of T3/4 patients in the non-HNT group, a survival advantage of an HNT cannot be validly demonstrated in our study. However, the HNT led to broader patient counselling regarding their therapy options. At the same time, a significant delay in therapy initiation could be seen, suggesting that workflows between diagnosis, HNT presentation, and therapy initiation should be optimized.

Abstract
Laryngeal cancer most frequently develops in males aged 60-70 years with a history of tobacco and/or alcohol use, while fewer cases occur in young patients in which tobacco and alcohol are often absent or less significant, highlighting the importance of other etiologies. We present cases of human papillomavirus (HPV)-associated laryngeal cancer in two previously healthy young women. A retrospective case review was carried out for both patients. DNA was extracted from the primary tumors and matched to normal tissue or blood, HPV genotype was determined by PCR and whole exome sequencing was carried out. Genomic results were pooled with laryngeal cancer patients from the cancer genome atlas (TCGA) dataset. The first patient was an 18-year-old female who underwent laryngectomy followed by adjuvant radiation. The second was a 24-year-old female who received chemoradiation. The first patient has remained disease-free for 16 years and the second for two years; both continue to be monitored. One tumor was positive for HPV45 and had mutations in FAT1 and FAT2; the other was positive for HPV31 and had mutations at NOTCH1, MAPK1, and HIST1H2AK. Both tumors had wild-type TP53 alleles. We bring attention to HPV as an etiology of laryngeal carcinoma in young patients, which may have implications for the treatment and prognosis of similar patients.

Abstract
INTRODUCTION In this study we analyzed CD105 (endoglin) and E-cadherin expression in laryngeal squamous cell carcinoma (LSCC) to evaluate their clinicopathologic significance. MATERIAL AND METHODS Expression of CD105 and E-cadherin was examined immunohistochemically using paraffin-embedded archival tissues of 72 (35 glottic and 37 supraglottic) previously untreated LSCC male patients. The mean value of the positively-stained microvessels for CD105 counted in four hot spots for each case was used as the final intratumoralmicrovessel density (MVD). A staining score of E-cadherin was calculated based on the percentage of cells stained (0-100%). RESULTS MVD was significantly higher in patients with advanced TNM stage (P = 0.004) and younger than 65 (P = 0.008). Nodal metastases were more frequent in the cases with low E-cadherin expression (P = 0.000). Tumor recurrence was associated with advanced TNM stage (P = 0.035) and high MVD (P = 0.002). A high MVD was an independent predictor of malignancy recurrence (P = 0.021). The log-rank test showed a significant difference in the disease-free interval in patients stratified according to the MVD value (P = 0.016). Spearman's rank correlation test did not show a significant correlation between E-cadherin and CD105 expression. CONCLUSIONS CD105-assessed MVD and expression of E-cadherin are promising prognostic factors for the outcome of patients with LSCC. Increased expression of CD105 could help predict patients with an increased risk of developing loco-regional recurrence after surgical treatment. Decreased E-cadherin expression is a potential predictor of lymph node metastases.

Abstract
A meta-analysis study to assess the effect of possible risk factors for pharyngocutaneous fistula (PCF) after total laryngectomy of laryngeal carcinoma. A comprehensive literature examination till January 2023 was implemented and 1794 linked studies were appraised. The picked studies contained 3140 subjects with total laryngectomy of laryngeal carcinomas in the picked studies' baseline, 760 of them were PCF, and 2380 were no PCF. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to calculate the consequence of possible risk factors for PCF after total laryngectomy of laryngeal carcinomas and surgical wound infection after total laryngectomy of laryngeal carcinoma by the dichotomous and continuous styles and a fixed or random model. The PCF had a significantly higher surgical wound infection (OR, 6.34; 95% CI, 1.89-21.27, P = .003) compared with the no PCF in total laryngectomy of laryngeal carcinomas. The smoking (OR, 1.73; 95% CI, 1.15-2.61, P = .008), and preoperative radiation (OR, 1.90; 95% CI, 1.37-2.65, P < .001) had significantly higher PCF as a risk factor in total laryngectomy of laryngeal carcinomas. The preoperative radiation had a significantly lower spontaneous PCF closure (OR, 0.33; 95% CI, 0.14-0.79, P = .01) compared with the no preoperative radiation in total laryngectomy of laryngeal carcinomas. However, the neck dissection (OR, 1.34; 95% CI, 0.75-2.38, P = .32), and alcohol intake (OR, 1.95; 95% CI, 0.76-5.05, P = .17), had no significant effect on PCF in total laryngectomy of the PCF had a significantly higher surgical wound infection, and preoperative radiation had a significantly lower spontaneous PCF closure in total laryngectomy of laryngeal carcinomas. Smoking and preoperative radiation were shown to be risk factors for PCF, however, neck dissection and alcohol intake were not shown to be risk factors for PCF in total laryngectomy of laryngeal carcinomas. Although precautions should be taken when commerce with the consequences because some of the picked studies for this meta-analysis was with low sample sizes.

Abstract
OBJECTIVE Because of the high costs associated with early-stage laryngeal carcinoma diagnosis and prognosis prediction, this study attempts to find valuable targets to establish a novel predictive model by focusing on the aldehyde dehydrogenase 2 (ALDH2) genotype and other peripheral blood markers. STUDY DESIGN Retrospective study. SETTING Tertiary comprehensive hospital. METHODS From January 2011 to January 2021, 362 cases of laryngeal carcinoma were included and divided into 2 groups in this retrospective analysis. Information on medical history, alcohol, and tobacco consumption habits, ALDH2 genotypes, and other peripheral blood markers was collected. Endpoints of the current study included disease-free survival and overall survival. A nomogram model for overall survival was established and evaluated using receiver operating characteristic (ROC) curves. RESULTS A total of 236 patients were included in the training cohort, and the other 126 were included in the validation cohort. The median follow-up of the patients was 9.6 years (interquartile range: 7.5-12.5 years). Peripheral fibrinogen, hemoglobin, and ALDH2 genotypes were significantly associated with an increase in laryngeal carcinoma mortality rate on Kaplan-Meier curves. The ROC curve showed that the effectiveness of overall survival prediction by the nomogram model was better than that of traditional clinical staging. CONCLUSION A prognostic nomogram of laryngeal carcinoma patients involving ALDH2 and peripheral blood markers and T and N stages was constructed and validated.

Abstract
Laryngeal carcinoma (LC) is the second most common malignant tumor of the head and neck. Due to its insidious nature, most patients have developed to the middle and late stages by the time they are diagnosed, missing the best treatment period. Thus, early detection, diagnosis and treatment are crucial to improve the prognosis of LC and enhance the quality of life of patients. In this study, a surface-enhanced Raman (SERS) sensing platform was developed by combining the magnetic beads (MBs) enrichment strategy and the antibody-DNA-mediated catalytic hairpin self-assembly (CHA) signal amplification technology. 4-Mercaptobenzoic acid (4-MBA) and hairpin DNA 1 (hpDNA1) were modified onto the surface of gold nanobipyramids (GNBPs) as SERS nanotags. Hairpin DNA 2 (hpDNA2) modified MBs were used as capture nanoprobes. Under the action of CHA and magnet-induced MBs enrichment, GNBPs can be assembled on the surface of MBs, forming high-density "hot spots" for the SERS signal enhancement. The results showed that the SERS sensing platform has the advantages of high sensitivity, high specificity and high reproducibility, with the limit of detection (LOD) low to pg/mL level. The expression level of CYFRA21-1 in serum of LC patients and healthy controls was successfully detected by the SERS sensing platform. The accuracy of the SERS results was verified by enzyme linked immunosorbent assay (ELISA). Therefore, this SERS sensor can be used for the detection of CYFRA21-1 in serum, providing a simple and reliable new method for the early diagnosis of LC.

Abstract
Recurrent laryngeal carcinoma presents differences from the primary tumor that largely depend on the treatment. In this article, we review the histologic and molecular treatment-induced changes that may affect the diagnosis of recurrent laryngeal carcinoma, the assessment of predictive markers, and the response to treatment with immune checkpoint inhibitors. Radiotherapy induces profound modifications that are strictly related to necrosis of different tissue components, fibrosis, and damage of the tumor vessels. Postradiotherapy recurrent/persistent laryngeal squamous cell carcinoma typically presents a discohesive growth pattern within a fibrotic background associated with significant changes of the tumor immune microenvironment, with both important immunosuppressive and immunostimulatory effects. Overall, the increase of immunoregulatory cells and immune checkpoints such as CTLA-4, TIM-3, PD-1, and PD-L1 induced by radiotherapy and chemotherapy strongly supports the use of immune checkpoint inhibitors in recurrent/persistent laryngeal carcinoma. Future studies aiming to identify predictive factors of the response to immune checkpoint inhibitors should consider such treatment-induced modifications.

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
BACKGROUND The aims of this study were to compare the survival outcomes of salvage vs. primary total laryngectomy (TL) in patients with locally advanced laryngeal or hypopharyngeal carcinoma and to determine their predictive factors. METHODS Overall (OS), cause-specific (CSS) and recurrence-free survival (RFS) of primary vs. salvage TL were compared in univariate and multivariate analysis taking into account other potential predictive factors (tumor site, tumor stage, comorbidity level etc.). RESULTS A total of 234 patients were included in this study. Five-year OS was 53% and 25% for the primary and salvage TL groups, respectively. Multivariate analysis confirmed the independent negative impact of salvage TL on OS (p = 0.0008), CSS (p < 0.0001) and RFS (p < 0.0001). Hypopharyngeal tumor site, ASA score ≥ 3, N-stage ≥ 2a and positive surgical margins were the main other predictors of oncologic outcomes. CONCLUSIONS Salvage TL is associated with significantly worse survival rates than primary TL highlighting the need for careful selection of patients who are candidates for larynx preservation. The predictive factors of survival outcomes identified here should be considered in the therapeutic decision-making, especially in the setting of salvage TL, given the poor prognosis of these patients.

Abstract
OBJECTIVE Little is known about the efficacy of using artificial intelligence (AI) to identify laryngeal carcinoma from images of vocal lesions taken in different hospitals with multiple laryngoscope systems. This multicentre study aimed to establish an AI system and provide a reliable auxiliary tool to screen for laryngeal carcinoma. STUDY DESIGN Multicentre case-control study. SETTING Six tertiary care centres. PARTICIPANTS Laryngoscopy images were collected from 2179 patients with vocal fold lesions. OUTCOME MEASURES An automatic detection system of laryngeal carcinoma was established and used to distinguish malignant and benign vocal lesions in 2179 laryngoscopy images acquired from 6 hospitals with 5 types of laryngoscopy systems. Pathological examination was the gold standard for identifying malignant and benign vocal lesions. RESULTS Out of 89 cases in the malignant group, the classifier was able to correctly identify laryngeal carcinoma in 66 patients (74.16%, sensitivity). Out of 640 cases in the benign group, the classifier was able to accurately assess the laryngeal lesion in 503 cases (78.59%, specificity). Furthermore, the region-based convolutional neural network (R-CNN) classifier achieved an overall accuracy of 78.05%, with a 95.63% negative predictive value and a 32.51% positive predictive value for the testing data set. CONCLUSION This automatic diagnostic system has the potential to assist clinical laryngeal carcinoma diagnosis which may improve and standardise the diagnostic capacity of laryngologists using different laryngoscopes.

Abstract
Purpose This paper aims to construct a surface-enhanced Raman spectroscopy (SERS) biosensor based on functionalized Au-Si nanocone arrays (Au-SiNCA) using a dual signal amplification strategy (SDA-CHA) to evaluate telomerase activity during epithelial-mesenchymal transition (EMT) in laryngeal carcinoma (LC). Methods A SERS biosensor based on functionalized Au-SiNCA was designed with an integrated dual-signal amplification strategy to achieve ultrasensitive detection of telomerase activity during EMT in LC patients. Results Labeled probes (Au-AgNRs@4-MBA@H1) and capture substrates (Au-SiNCA@H2) were prepared by modifying hairpin DNA and Raman signal molecules. Using this scheme, telomerase activity in peripheral mononuclear cells (PMNC) could be successfully detected with a limit of detection (LOD) as low as 10-6 IU/mL. In addition, biological experiments using BLM treatment of TU686 effectively mimicked the EMT process. The results of this scheme were highly consistent with the ELISA scheme, confirming its accuracy. Conclusion This scheme provides a reproducible, selective, and ultrasensitive assay for telomerase activity, which is expected to be a potential tool for the early screening of LC in future clinical applications.

Abstract
The increase in diagnostic and therapeutic procedures in the treatment of oncological diseases, as well as the limited capacity of experts to provide information, necessitates the development of therapy decision support systems (TDSS). We have developed a treatment decision model that integrates available patient information as well as tumor characteristics. They are assessed according to their relevance in evaluating the optimal therapy option. Our treatment model is based on Bayesian networks (BN) which integrate patient-specific data with expert-based implemented causalities to suggest the optimal therapy option and therefore potentially support the decision-making process for treatment of laryngeal carcinoma. To test the reliability of our model, we compared the calculations of our model with the documented therapy from our data set, which contained information on 97 patients with laryngeal carcinoma. Information on 92 patients was used in our analyses and the model suggested the correct treatment in 419 out of 460 treatment modalities (accuracy of 91%). However, unequally distributed clinical data in the test sets revealed weak spots in the model that require revision for future utilization.

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
There are no reliable immunohistochemical markers for diagnosing laryngeal squamous cell carcinoma (SCC) or diagnosing and grading laryngeal dysplasia. We aimed to evaluate the diagnostic utility of CK8, CK10, CK13, and CK17 in benign laryngeal lesions, laryngeal dysplasia, and laryngeal SCC. This retrospective study included 151 patients diagnosed with laryngeal papilloma, laryngeal polyps, laryngeal dysplasia, and laryngeal SCC who underwent surgical treatment between 2010 and 2020. Immunohistochemistry (IHC) was carried out using specific monoclonal antibodies against CK8, CK10, CK13, and CK17. Two experienced pathologists performed semi-quantitative scoring of IHC positivity. The diagnostic significance of the markers was analyzed. CK13 showed a sensitivity of 100% and a specificity of 82.5% for distinguishing between laryngeal SCC and laryngeal dysplasia and benign lesions. CK17 showed a sensitivity of 78.3% and specificity of 57.1% for the detection of laryngeal SCC vs. laryngeal dysplasia. CK10 showed a sensitivity of 80.0% for discriminating between low-grade and high-grade dysplasia, and a specificity of 61.1%. Loss of CK13 expression is a reliable diagnostic tool for diagnosing laryngeal lesions with malignant potential and determining resection lines. In lesions with diminished CK13 expression, CK17 could be used as an auxiliary immunohistochemical marker in diagnosing laryngeal SCC. In CK13-negative and CK17-positive lesions, CK10 positivity could be used to determine low-grade dysplasia. CK8 is not a useful IHC marker in differentiating between benign laryngeal lesions, laryngeal dysplasia, and laryngeal SCC.

Abstract
Chemoradiation is the standard treatment for patients with locally advanced laryngeal carcinoma with intact cartilage and functional larynx. The aim of this retrospective study was to assess overall survival (OS) and disease-free survival (DFS) of patients with locally advanced (stage III and stage IV) squamous cell carcinoma of the larynx who have been treated with definitive radical radiotherapy (RT) with or without chemotherapy in a tertiary cancer center in India between January 1, 2006 and December 31, 2015. Data were collected using structured proforma. The patients were treated with RT alone, induction chemotherapy (IC) followed by RT, concurrent chemoradiation therapy (CCRT) or IC followed by CCRT. Response assessment was conducted at 3-4 months post-treatment. Patient-, tumor- and treatment-related factors were documented and were associated with DFS and OS. Survival curves were generated using the Kaplan-Meier method and the statistical significance of survival curves was assessed using the log-rank test. Prognostic factors were assessed using the Cox proportional hazards regression model. A total of 630 patients were included in the present study. The most common age group at presentation was 50-70 years (n=477; 75.7%) and 95.4% (n=601) patients were male. The most common stage at presentation was stage III (n=367, 58.1%). The median follow-up period for the entire group of was 59 months (range, 2-175 months). A complete response after treatment was seen in 549 patients (87.1%). Salvage surgery was performed for 11 patients with residual disease. A total of 134 patients (21.3%) had developed locoregional and distant relapses, and salvage surgery was performed for 31 out of 102 patients with locoregional relapse. The 5-year OS was 48.7% and the 5-year DFS was 45.7%. The stage-wise OS rates were 58.9, 34.9 and 30.4% (P=0.001) and the stage-wise DFS rates were 56.3, 32.0 and 21.7 (P=0.001) for stage III, IVa and IVb, respectively. Results from the present study demonstrated the feasibility of delivery of chemoradiation protocols with good results in a developing country.

Abstract
Pyroptosis, a newly-defined mode of cell death related to inflammation, is closely related to cancers but has not yet been studied in laryngeal carcinoma (LC). We investigated pyroptosis in LC and constructed a prognostic model. Using RNA sequencing data, we identified differentially expressed genes (DEGs) in LC and normal tissues to construct a prognostic risk model. The model's accuracy and independent prognostic value were evaluated using survival- and receiver operating characteristic (ROC)- curves; and univariate and multivariate Cox regression analyses, respectively. Gene Expression Omnibus (GEO) data was utilized as a model validation set. Differential analysis revealed 37 DEGs, and consistent clustering showed that pyroptosis-related genes could predict LC prognosis. Six genes (CHMP7, GSDME, GZMB, CASP9, IL6, and NLRP1) were obtained by Lasso Cox regression analysis to construct a prognostic model. The high-risk group had a poor prognosis with areas under the ROC curve at 1-, 3-, and 5-years of 0.619, 0.692, and 0.656, respectively. Univariate and multivariate Cox analyses showed that the risk score was an independent prognostic factor. Enrichment analysis of GO and KEGG pathways revealed that differentially expressed genes may be related to infection, T cell differentiation, immunity, and inflammation. It was further found that the low survival rate of the high-risk group may be related to the significant reduction of immune cell infiltration and immune function. With the bioinformatic method, six genes related to pyroptosis affecting LC prognosis were screened and a prognostic risk model was constructed, which laid a foundation for pyroptosis study in LC.

Abstract
BACKGROUND This study explored whether laryngeal carcinoma could be divided into different subtypes based on molecular differences using a molecular subtype-prediction model. METHODS We extracted data from the Cancer Genome Atlas and Gene Expression Omnibus databases and then performed unsupervised cluster analysis to identify discrete molecular subtypes of laryngeal carcinoma. Significance analysis of microarrays was performed to detect differentially expressed genes for each subtype, and gene set enrichment analysis and the GenCliP3 software were used to label gene functions and identify key pathways. RESULTS We categorized 126 patients into C1 and C2 molecular subtypes associated with pathologic grade. The C2 subtype appeared more aggressive, with a worse prognosis. The most significant enrichment pathway of the C2 subtype was the Hedgehog pathway, and GLI1 was a core gene. CONCLUSIONS Laryngeal carcinoma can be divided into two subtypes based on differences in molecular expression, which could identify key molecules associated with prognosis.

Abstract
BACKGROUND Markers of tumorigenesis are essential factors which may play a major role in the early detection of head and neck carcinoma. AIMS/OBJECTIVES To assess concentration of HIF-1, GLUT1 and VEGF in tissue samples and blood serum and its correlation to the tumour size, nodal disease, pathologic differentiation and patients' data. MATERIAL AND METHODS Fifty-two patients diagnosed with laryngeal carcinoma stage I-IV in which concentration of HIF-1, GLUT1 and VEGF was assessed in tissue samples and blood serum using immunoassay method. RESULTS HIF-1α, GLUT1, VEGF concentration was significantly higher in cancer tissue samples than in normal tissue (p < .001) and benign laryngeal lesions. Serum levels of the factors were significantly lower in the control group. Statistically significant difference regarding tumour size was found between T2 and T4 stages in HIF-1α concentration in cancer samples and serum. CONCLUSIONS The results show that high concentration of HIF-1α, GLUT1 and VEGF might be suggestive of carcinogenic process when diagnosing patients with laryngeal lesions and could promote early detection of malignancy. SIGNIFICANCE The results of this study show importance of biochemical assessment in malignant tumours which may affect clinical decisions.

Abstract
OBJECTIVE To evaluate whether neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR) and monocyte-to-white blood cell ratio (MWR) can be used as diagnostic and prognostic markers for laryngeal carcinoma (LC). METHODS In this retrospective study, 50 patients with LC treated in the Department of Otolaryngology, Head and Neck Surgery of Beijing Tongren Hospital from August 2014 to August 2015 were enrolled in research group. In addition, 40 healthy volunteers from the same period were selected as control group. The counts of white blood cells, neutrophils, lymphocytes, monocytes and platelets in the peripheral blood of participants were measured with a blood counting instrument (Sysmex XE-2100, Sysmex Corporation, Japan), and the NLR, PLR, LMR and MWR were calculated. After that, the survival rate of patients was observed through a 5-year follow-up. The prognostic value of the above four indexes and their combination was discussed in patients with different clinical characteristics. RESULTS Compared with the control group, the NLR, PLR and MWR were higher and the LMR was lower in the research group. In terms of survival, patients with higher NLR, PLR and MWR and lower LMR showed a higher 5-year mortality than those with lower NLR, PLR and MWR and higher LMR, indicating that NLR, PLR and MWR were higher and LMR was lower in the survival group than in the death group. Subsequent analysis identified that NLR, PLR, LMR and MWR were closely correlated with age, alcohol drinking, smoking, clinical staging and T-staging. Clinical staging, T-staging, NLR, PLR, LMR, and MWR were confirmed as influencing factors for LC. CONCLUSIONS NLR, PLR, LMR, and MWR can be used as diagnostic and prognostic markers for LC and their combination has a superior diagnostic performance.

Abstract
Laryngeal carcinoma is the most common malignant tumor of the upper respiratory tract. Total laryngectomy provides complete and permanent detachment of the upper and lower airways that causes the loss of voice, leading to a patient's inability to verbally communicate in the postoperative period. This paper aims to exploit modern areas of deep learning research to objectively classify, extract and measure the substitution voicing after laryngeal oncosurgery from the audio signal. We propose using well-known convolutional neural networks (CNNs) applied for image classification for the analysis of voice audio signal. Our approach takes an input of Mel-frequency spectrogram (MFCC) as an input of deep neural network architecture. A database of digital speech recordings of 367 male subjects (279 normal speech samples and 88 pathological speech samples) was used. Our approach has shown the best true-positive rate of any of the compared state-of-the-art approaches, achieving an overall accuracy of 89.47%.

Abstract
Hypoxic resistance is the main obstacle to radiotherapy for laryngeal carcinoma. Our previous study indicated that hypoxia-inducible factor 1α (HIF-1α) and glucose transporter 1 (Glut-1) double knockout reduced tumour biological behaviour in laryngeal carcinoma cells. However, their radioresistance mechanism remains unclear. In this study, cell viability was determined by CCK8 assay. Glucose uptake capability was evaluated by measurement of 18 F-fluorodeoxyglucose radioactivity. A tumour xenograft model was established by subcutaneous injection of Tu212 cells. Tumour histopathology was determined by haematoxylin and eosin staining, immunohistochemical staining, and TUNEL assays. Signalling transduction was evaluated by Western blotting. We found that hypoxia induced radioresistance in Tu212 cells accompanied by increased glucose uptake capability and activation of the PI3K/Akt/mTOR pathway. Inhibition of PI3K/Akt/mTOR activity abolished hypoxia-induced radioresistance and glucose absorption. Mechanistic analysis revealed that hypoxia promoted higher expressions of HIF-1α and Glut-1. Moreover, the PI3K/Akt/mTOR pathway was a positive mediator of HIF-1α and/or Glut-1 in the presence of irradiation. HIF-1α and/or Glut-1 knockout significantly reduced cell viability, glucose uptake and PI3K/Akt/mTOR activity, all of which were induced by hypoxia in the presence of irradiation. In vivo analysis showed that knockout of HIF-1α and/or Glut-1 also inhibited tumour growth by promoting cell apoptosis, more robustly compared with the PI3K inhibitor wortmannin, particularly in tumours with knockout of both HIF-1α and Glut-1. HIF-1α and/or Glut-1 knockout also abrogated PI3K/Akt/mTOR signalling transduction in tumour tissues, in a manner similar to wortmannin. HIF-1α and/or Glut-1 knockout facilitated radiosensitivity in laryngeal carcinoma Tu212 cells by regulation of the PI3K/Akt/mTOR pathway.

Abstract
Large cell neuroendocrine carcinoma (LCNEC) of the larynx is an exceedingly rare cancer of the head and neck that is difficult to diagnose. Few case reports of laryngeal LCNEC exist within the literature, and it was not until recently that LCNEC was recognized as a discrete subtype of neuroendocrine carcinoma. Given its recent recognition as a distinct subtype, histologic characteristics distinguishing LCNEC from other poorly differentiated carcinomas remain under investigation. Various reports have shown genetic alterations such as p53 and/or p16 overexpression, which are typically associated with infection by human papilloma virus (HPV). However, some reports have shown p53 and/or p16 overexpression in HPV negative samples. In this case, we discuss a 67-year-old patient with a history of extensive alcohol and tobacco use with a newly diagnosed T4N0M0, high grade, LCNEC of the subglottic larynx. Tumor pathology demonstrated positive staining for typical neuroendocrine (NE) markers like synaptophysin and chromogranin A; however, there was diffuse CK34βE12 and p16 expression. LCNEC is a newly classified subtype of poorly differentiated neuroendocrine (NE) tumors, and the diagnosis requires consideration of the clinical presentation, microscopic features, and immunostaining markers.

Abstract
OBJECTIVES Alcohol consumption is closely associated with prognosis for laryngeal squamous cell carcinoma (LSCC) patients. As key enzymes in ethanol metabolism, proteins in the alcohol dehydrogenase (ADH) family make for valuable targets to establish a novel predictive nomogram model. This study attempts to do so by focusing on the single nucleotide polymorphisms (SNPs) of ADH1B and ADH1C in LSCC. METHODS Sixty eight LSCC patients that were followed up for more than 10 years were retrospectively analyzed. Endpoints of the current study included disease-free survival and overall survival. Survival analyses were performed using the Kaplan-Meier method and evaluated by log-rank test. The prognostic value of eight ADH1B SNPs and three ADH1C SNPs were evaluated using univariate and multivariate Cox regression analyses. A nomogram model for disease-free survival was established and evaluated using the receiver operating characteristic curve, the C-index, and a calibration plot. RESULTS Significant association was exhibited between rs17033 (p < 0.001) and rs1229984 (p = 0.002) with an increase in LSCC recurrence rate on Kaplan-Meier curves. Multivariate logistic regression analysis revealed that the rs17033 polymorphism of ADH1B was independently associated with an increased risk of LSCC recurrence (HR = 3.325, 95% CI = 1.684-6.566, p = 0.001). Based on these findings, a prognostic nomogram of LSCC patients involving ADH1B rs17033 was constructed. CONCLUSION This study has demonstrated an independent association between ADH1B gene variants and the recurrence of LSCC. A nomogram model based on rs17033 of ADH1B, age, T, and N stages were successfully developed for the first time to predict the probability of recurrence in LSCC patients.

Abstract
Objective To investigate the effects of NK4 gene on the properties and tumorigenicity in laryngeal squamous cell carcinoma cell. Methods Here, we used the attenuated Salmonella carrying the NK4 gene to transfect the AMC-HN-8 cells and detected the expression of NK4 by the real-time quantitative polymerase chain reaction (q RT-PCR). The properties of NK4 gene was determined by MTT method, cell scratch test, and flow cytometry. A nude mouse tumorigenesis model was used to evaluate the effect of NK4 gene on the growth of AMC-HN-8 cells in vivo. While a western blot assay was used to assess the expression of DKK1, Wnt1 and β-Catenin in nude mouse tumors. Results qRT-PCR showed that the expression of NK4 in the transfection group was significantly higher than that in the control group (P<0.01), and the expression increased with the time of transfection. MTT results showed NK4 overexpression inhibited the proliferation of AMC-HN-8 cells, and the inhibitory activity no longer increased with increasing dose when 30% expression supernatant was added (P<0.01). Scratch experiment showed that NK4 overexpression decreased the cell migration ability (P<0.01). Annexin V/PI double staining experiment showed that NK4 gene induced AMC-HN-8 cell apoptosis (P<0.01), and cell cycle arrest in S phase (P<0.01). NK4 overexpression inhibited tumor formation ability of AMC-HN-8 cells in vivo (P <0.05). WB detection showed that the expression of DKK1 increased, Wnt1 and β-Catenin protein decreased after the high expression of NK4. Conclusions NK4 gene inhibit cell proliferation and migration, while promote cell apoptosis, and induce cell cycle arrest in S phase of laryngeal carcinoma AMC-HN-8 cells. NK4 overexpression inhibit the tumorigenesis ability of AMC-HN-8 cells, which may be related to the regulation of DKK1/Wnt1/β-Catenin signal axis.

Abstract
Background. Among patients with diagnosis of Laryngeal Squamous Cell Carcinoma (LSCC), up to 37.5% of cases may have occult metastasis (OM), and this feature is linked to poor prognosis and high rate of local recurrence. The role of elective neck dissection (END) in clinically negative neck (cN0) LSCC remains controversial. It is of great value to search for low-cost and easily detectable indicators to predict the risk of OM in laryngeal cancer. Recent reports have shown that high values of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) represent a negative prognostic factor in head and neck cancers. The aim of our study has been to investigate the value of pre-treatment NLR and PLR with regard to predicting occult cervical metastasis in cN0 supraglottic and glottic LSCC. Materials and methods. Data of patients affected by LSCC, who had been surgically treated by means of laryngectomy (total, horizontal partial and supracricoid) and END between January 2006 and January 2021, were retrospectively reviewed, using information retrieved from a database dedicated to such procedures in a single tertiary care referral institute. Results. A total of 387 patients were treated for LSCC at our Institute from 2006 to 2021, but only 108 of them met the inclusion criteria. The median age at the time of diagnosis was 64 years (range, 39–89 years). All the tumors were treated with a laryngectomy and an END. A total of 27.7% of patients were found positive for neck node metastasis (the pN+ group), while 78/108 (72.3%) patients were found to be negative for the presence of neck metastasis (the pN0 group). High values of NLR, but not PLR, significantly correlated with the probability of OM, and according to the iterative algorithm of Newton–Raphson, an NLR value of 2.26 corresponds to a probability of OM of 20%. Conclusion. Our analysis revealed a statistical correlation between high NLR pre-treatment values and positive neck OM in patients with LSCC.

Abstract
Purpose Hexokinase-II (HK-II) is the key enzyme in the first rate-limiting step of glycolysis that catalyzes the conversion of glucose to glucose-6-phosphate. Here, we examined the association between HK-II expression and radioresistance in laryngeal carcinoma and whether the inhibition of HK-II expression can enhance the radiosensitivity of these tumors. Methods The effects of HK-II small interfering RNA (siRNA) on the radiosensitivity of Tu212 cells were examined in vitro and in vivo in a mouse model. Cells were irradiated using a 6-MV linear accelerator. The cell viability, cell survival, proliferation, apoptosis, and cell cycle of Tu212 cells were evaluated using trypan blue staining, colony formation assays, CCK-8 assays, and flow cytometry, respectively. Oxygen consumption, lactic acid production, glucose consumption, and the ATP level of Tu212 cells were also examined. The expression of glycolytic and regulatory enzymes involved in the tricarboxylic acid cycle was assessed using Western blotting. Results The HK-II siRNA and X-ray combination treatment led to a significantly greater reduction of cell viability, inhibition of cell survival and proliferation, increased apoptosis, and increased G2 phase arrest compared to either treatment alone (all, P<0.01). HK-II siRNA increased the oxygen consumption rate of cells, significantly inhibited lactic acid production and glucose consumption, and significantly suppressed the upregulation of HK-II, pyruvate kinase M2 (PKM2), pyruvate dehydrogenase (PDH), phosphofructokinase platelet (PFKP), lactate dehydrogenase (LD), and citrate synthase (CS) (all, P<0.01). Conclusion The inhibition of HK-II by siRNA enhances the radiosensitivity of laryngeal carcinoma Tu212 cells by inhibiting glycolysis and partially inhibiting oxidative phosphorylation.

Abstract
Over the past few decades, several publications have investigated the role of Epstein-Barr virus (EBV) in head and neck squamous cell carcinomas, and an increasing number of them have shown its presence in laryngeal tumors. The purpose of this meta-analysis was to evaluate the association of EBV with laryngeal carcinoma. The search was carried out in two databases, Scopus and PubMed, using the following terms: “Epstein-Barr virus” and “laryngeal carcinoma”. A total of 187 records were found, of which 31 were selected for meeting the inclusion and exclusion criteria. The meta-analysis yielded an overall pooled prevalence of 43.72% (95% confidence interval (CI): 34.35–53.08). Studies carried out in Europe and Eurasia had slightly higher pooled prevalence than other subgroups, while the prevalence of studies performed in developed countries was higher than in developing countries (46.37% vs. 34.02%). Furthermore, laryngeal carcinoma occurred almost three times as often among EBV-infected individuals compared to those without EBV infection (odds ratio = 2.86 (95% CI: 1.18–6.90); Begg’s test, p = 0.843 and Egger’s test, p = 0.866). Our findings support the idea that EBV is related to laryngeal carcinoma. However, further studies are needed before recognizing a definitive etiological role of EBV in the development and/or progression of laryngeal carcinomas.

Abstract
Laryngeal carcinoma (LC) is a common head and neck cancer, which is the result of mutational changes due to gene dysregulation and etiological factors such as tobacco and smoking. A large number of patients received a poor prognosis due to diagnosis at an advanced stage. This highlights the need for definitive, early, and efficient diagnoses. With rapid development of high‐throughput sequencing, circular RNA (circRNA) has been reported to play a pivotal role in cancer. CircRNA functions as a microRNA (miRNA) sponge in the regulation of mRNA expression, forming circRNA‐miRNA regulatory axis. In this review, we described the axis in LC. The result indicated that CDR1as, hsa_circ_0042823, hsa_circ_0023028, circPARD3, hsa_circ_103862, hsa_circ_0000218, circMYLK, circCORO1C, hsa_circ_100290, circ‐CCND1, hsa_circ_0057481, circFLAN, and circRASSF2 expressed higher in LC, whereas, hsa_circ_0036722 and hsa_circ_0042666 expressed lower. The circRNAs regulated the target genes by sponging miRNAs and contributed to the pathogenesis of LC.

Abstract
Laryngeal cancer is a common type of head and neck malignancy. microRNA is implicated in the development and progression of various tumours. The present study aimed to explore the potential roles and mechanisms of miR-646 in laryngeal carcinoma cells. We detected the expression of miR-646 and observed that miR-646 was reduced in laryngeal cell lines. Subsequently, the proliferation, migration and invasion of TU212 and TU686 cells were evaluated using CCK-8 assays, cell proliferation ELISA BrdU and transwell assays after transfection with miR-646 mimic. Overexpression of miR-646 attenuated the proliferative and invasive abilities of TU212 and TU686 cells. Dual luciferase reporter assay confirmed that glutathione peroxidase 1 (GPX1) is a direct target of miR-646. Interestingly, restoration of GPX1 promoted cell proliferation and migration, and reversed the biological activities of miR-646 in cell proliferation and migration. It is worth noting that miR-646 overexpression blocked the activation of PI3K/AKT pathway, and this was partly abrogated by GPX1. 740Y-P, a PI3K agonist abolished the effects of miR-646 on cell proliferation and invasion. Taken together, miR-646 prohibited the proliferation and invasion of laryngeal carcinoma cells through the PI3K/AKT pathway via targeting GPX1.

Abstract
Simple Summary IMP3 expression was analyzed in patients with malignant (laryngeal squamous cell carcinoma), semi-malignant (dysplasia) and benign (nodules, polyps) laryngeal lesions and correlated with clinical characteristics. Higher IMP3 stains were particularly found in malignant laryngeal pathologies, which might be useful for differentiation between premalignant and malignant lesions. In laryngeal cancer patients, higher IMP3 expression was associated with positive neck nodes and worse disease-specific survival. Abstract Background: The aim of this study was to (i) determine IMP3 protein expression in benign and malignant laryngeal lesions, (ii) compare its expression to Ki-67, p53, cyclin D1, and (iii) finally, to examine the prognostic power of IMP3 in squamous cell carcinomas of the larynx (LSSC). Methods: IMP3 protein expression was evaluated in 145 patients, including 62 LSCC, 45 dysplasia (25 with low and 20 with high-grade dysplasia), and 38 benign lesions (vocal cord polyps and nodules). Results: IMP3 was significantly higher expressed in LSCC compared to dysplasia and benign lesions (p < 0.001; p < 0.001, respectively). Similarly, higher expression patterns were observed for Ki-67 and p53, whereas cyclin D1 was equally distributed in all three lesions. IMP3 (p = 0.04) and Ki-67 (p = 0.02) expressions were significantly linked to neck node positivity, and IMP3 overexpression to worse disease-specific survival (p = 0.027). Conclusion: Since IMP3 showed significantly higher expression in laryngeal carcinomas, but not in high- or low-grade dysplasia, it serves as a useful marker to differentiate between invasive and noninvasive lesions. Higher IMP3 expression represented a significantly worse prognosticator for clinical outcomes of patients with squamous cell carcinoma of the larynx.

Abstract
Objective Open partial horizontal laryngectomies (OPHLs) nowadays represent the first line surgical choice for the conservative treatment of locally intermediate and selected advanced stage laryngeal cancers. Among the peculiarities of OPHLs, there is the possibility of intraoperatively modulating the procedure. It would be useful for the surgeon to recognise preoperative endoscopic and radiological factors that can predict the possibility to modulate the laryngectomy. Methods The present study retrospectively reviewed a cohort of 72 patients who underwent OPHL for glottic LSCC, in order to identify preoperative (endoscopic and radiological) parameters that are able to predict modulation surgery. Results The hypoglottic extension of the glottic tumour was the preoperative finding that was most informative in predicting OPHL modulation. However, it had no significant impact on oncological outcomes. Conclusions Patients affected by tumours with hypoglottic extension and eligible for OPHL type II should be preoperatively informed about the possibility of an intraoperative switch towards OPHL type III.

Abstract
BACKGROUND Contrast-enhanced ultrasound (CEUS) is considered an attractive imaging technique to evaluate tumor microcirculation. However, the validity of CEUS for assessing laryngeal carcinoma is unclear. PURPOSE To compare the performance of CEUS with conventional US and contrast-enhanced computed tomography (CECT) in the diagnosis and preoperative T-staging of laryngeal carcinoma. MATERIAL AND METHODS Forty-one consecutive patients with laryngeal carcinoma underwent conventional high-frequency US, CEUS, and CECT before surgery. The CEUS characteristics of laryngeal carcinoma were recorded. The imaging findings of CEUS and conventional US were compared with CECT findings and the postoperative pathological examination. RESULTS CEUS showed hyperenhancement in 38 cases and isoenhancement in three cases. Homogeneous distribution of contrast agent was found in 20 cases and heterogeneous distribution in 21 cases, of which 16 cases showed local perfusion defects. In the enhanced phase, rapid entry was observed in 37 cases, synchronous entry was observed in two cases, and slow entry was observed in two cases. Rapid exit was observed in 25 cases and slow exit was observed in 16 cases. The pretherapeutic T-staging accuracy was not significantly different between conventional US, CEUS, and CECT (P ≥ 0.500). A high sensitivity and specificity were achieved by CEUS in the evaluation of involvement of thyroid cartilage. CONCLUSION Compared with conventional US and CECT, CEUS has a reliable initial T-staging accuracy and diagnostic properties for detecting laryngeal cartilage invasion.

Abstract
Metastatic cardiac tumors are mainly diagnosed postmortem, while cardiac metastases of laryngeal cancer are exceedingly rare. We report a case of laryngeal carcinoma with subsequent metastatic disease to the heart diagnosed nine months after surgical resection of laryngeal cancer. Additionally, we attempted to summarize published case reports of laryngeal cancer with cardiac metastasis. Retrospective chart review and literature search via PubMed and Google Scholar were performed. Twenty cases of laryngeal squamous cell carcinoma (SCC) with cardiac metastatic tumors were identified. We described demographics, typical features seen on diagnostic studies, and analyzed current literature on incidence, diagnostic studies, treatment options, and prognosis of secondary cardiac tumors. More data are needed to decide on the optimal treatment strategy for metastatic cardiac disease.

Abstract
Aberrant expression or mutation of the Septin gene family is closely associated with cancer progression, and septin 2 (SEPT2) exerts its tumor-promoting effects in multiple cancers, but its role in regulating laryngeal squamous cell carcinoma (LSCC) progression and drug resistance has not been investigated. Based on the published data, the present study identified that SEPT2 promoted cancer progression and increased cisplatin-resistance in LSCC, and a novel LncRNA FGD5-AS1/miR-497-5p axis was crucial for this process. Mechanistically, SEPT2 tended to be enriched in LSCC tissues and cells, and knock-down of SEPT2 inhibited cell proliferation, viability, migration, and tumorigenesis in LSCC cells in vitro and in vivo. Aside from that, SEPT2 overexpression increased cisplatin resistance in LSCC cells. Next, by conducting the dual-luciferase reporter gene system assay, we identified that the LncRNA FGD5-AS1/miR-497-5p axis regulated SEPT2 in LSCC. Specifically, LncRNA FGD5-AS1 sponged miR-497-5p to upregulate SEPT2 in LSCC cells in a competing endogenous RNA (ceRNA) mechanisms-dependent manner. Interestingly, upregulated LncRNA FGD5-AS1 and downregulated miR-497-5p were observed in LSCC tissues and cells, and LncRNA FGD5-AS1 ablation inhibited cancer progression. Also, LncRNA FGD5-AS1 overexpression increased cisplatin-resistance in LSCC by modulating the miR-497-5p/SEPT2 axis. Collectively, we conclude that targeting the LncRNA FGD5-AS1/miR-497-5p/SEPT2 signaling cascade may be an alternative strategy to treat LSCC in the clinic.

Abstract
In this study, we investigated the ability of curcumin alone or in combination with GLUT1 siRNA to radiosensitize laryngeal carcinoma (LC) through the induction of autophagy. Protein levels in tumour tissues and LC cells were measured by immunohistochemistry and Western blotting. In vitro, cell proliferation, colony formation assays, cell death and autophagy were detected. A nude mouse xenograft model was established through the injection of Tu212 cells. We found that GLUT1 was highly expressed and negatively associated with autophagy-related proteins in LC and that curcumin suppressed radiation-mediated GLUT1 overexpression in Tu212 cells. Treatment with curcumin, GLUT1 siRNA, or the combination of the two promoted autophagy. Inhibition of autophagy using 6-amino-3-methypourine (3-MA) promoted apoptosis after irradiation or treatment of cells with curcumin and GLUT1 siRNA. 3-MA inhibited curcumin and GLUT1 siRNA-mediated non-apoptotic programmed cell death. The combination of curcumin, GLUT1 siRNA and 3-MA provided the strongest sensitization in vivo. We also found that autophagy induction after curcumin or GLUT1 siRNA treatment implicated in the AMP-activated protein kinase-mTOR-serine/threonine-protein kinase-Beclin1 signalling pathway. Irradiation primarily caused apoptosis, and when combined with curcumin and GLUT1 siRNA treatment, the increased radiosensitivity of LC occurred through the concurrent induction of apoptosis and autophagy.

Abstract
INTRODUCTION UK population ageing and associated cancer risk predicts an increase in the prevalence of laryngeal cancer in elderly patients. Whilst trans-oral laser microsurgery (TLM) has been demonstrated to achieve excellent control of early disease with few complications, data specifically related to its safety and efficacy in older patients is lacking. We report the largest series to date. OBJECTIVES To assess the safety and efficacy of TLM in elderly patients with glottic pre-malignancy and early malignancy. METHODS A retrospective review and statistical analysis of the clinical records of patients aged 70 or over undergoing TLM for early and premalignant glottic disease. RESULTS The records of 106 patients over the age of 70 were identified. Thirteen records were excluded, 4 due to failure to meet the inclusion criteria (stage I/II disease, primary site of lesion in the glottis) and 9 due to incomplete follow up data capture. Most surgeries (>70%) were performed as a day case or overnight admission, with only 2 admissions >2 days. One patient required hospital readmission with dysphagia, resulting in an altered diet. No patients required tracheostomy or tube feeding. No treatment related deaths or intensive care admissions were observed. Ten patients had recurrent disease within 5 years; 1 received radiotherapy, 1 underwent salvage laryngectomy, the remainder had further TLM without complication. Five-year disease specific survival rates were >90%. CONCLUSION Our results demonstrate that TLM is safe and effective for elderly patients, with outcomes comparable to those reported in large, non-age selected cohorts. Although our patients underwent more conservative cordectomy types (I-III) than those with similar disease stages reported elsewhere, our recurrence rates were not higher. This supports the oncological effectiveness of surgery whilst reducing the risk of associated functional compromise.

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

Abstract
Drug resistance is one of the main factors limiting the efficacy of chemotherapy in patients with laryngeal cancer; thus, it is important to investigate the drug resistance of laryngeal cancer. In the present study, the mechanism of the regulation of drug resistance in laryngeal cancer cells by ATP-binding transporter G2 (ABCG2) that is present in the extracellular vesicles (EVs) released by drug-resistant cells was studied in vivo and in vitro. A cisplatin (CDDP)-resistant cell line (AMC-HN-8/CDDP) was established from AMC-HN-8 cells by continuous exposure to increasing concentrations of CDDP. The EVs extracted from the culture medium of AMC-HN-8/CDDP and AMC-HN-8 cells were termed EVs1 and EVs2, respectively. Following 48-h treatment of AMC-HN-8 cells with EVs1 or EVs2, the cells were designated as AMC-HN-8-EVs1 or AMC-HN-8-EVs2. Nude mice bearing AMC-HN-8-EVs1 and AMC-HN-8 cell-derived xenograft tumors were established to detect the effects of EVs on drug resistance. The resistance index of AMC-HN-8/CDDP cells to CDDP was 5.60, which was determined by the MTT assay. The mRNA and protein expression levels of ABCG2 in AMC-HN-8/CDDP cells and EVs1 were significantly higher compared with those in AMC-HN-8 cells and EVs2, respectively (P<0.01). The ABCG2 mRNA and protein levels, and the proliferation index of AMC-HN-8-EVs1 cells were significantly higher compared with those of AMC-HN-8-EVs2 and AMC-HN-8 cells (P<0.01), whereas the apoptotic rate was significantly lower (P<0.01). The mean volume of subcutaneous tumor xenografts in the test group (inoculated with AMC-HN-8-EVs1 cells and intraperitoneally injected with 3 mg/kg CDDP) was significantly higher compared with that in the control group (inoculated with AMC-HN-8 cells and intraperitoneally injected with 3 mg/kg CDDP) (P<0.01), whereas the apoptotic rate of tumor cells was significantly lower (P<0.01). The ABCG2 mRNA and the protein expression levels in the tumor cells of the test group were significantly higher compared with those in the blank (inoculated with AMC-HN-8 cells and was intraperitoneally injected with normal saline) and control groups (P<0.01). The high expression levels of ABCG2 in laryngeal carcinoma cells affected the drug resistance of the cells. The EVs released by drug-resistant cells upregulated the expression of ABCG2 and induced drug resistance in laryngeal carcinoma cells, which may be dependent on the ABCG2 gene carried by the EVs.

Abstract
Introduction Chemo-radiotherapy (CRT) has increasingly been employed for the treatment of laryngeal cancer at T3 or higher rather than total laryngectomy (TL), in order to preserve the larynx. However, TL is still frequently performed in patients with advanced laryngeal cancer, especially T4 disease. When CRT is performed for advanced cancer, there is a certain rate of residual disease or relapse, and TL is conducted as salvage surgery for those patients, but TL following CRT is associated with a high incidence of postoperative complications. Objective The purpose of this study was to investigate the influence of preoperative radiation therapy on the occurrence of postoperative complications of TL, particularly pharyngocutaneous fistula (PCF). Methods We retrospectively investigated 142 patients who underwent TL for laryngeal cancer whether postoperative complications were related to a history of radiation therapy or neck dissection. Detailed investigation of the 32 patients who underwent radiation therapy was also conducted. Results PCF was significantly higher after radiation therapy. Neck dissection was not related. As the time from radiation therapy to TL decreased, the incidence rate of postoperative PCF increased and the time to closure became significantly longer. Preoperative laboratory tests did not show a significant difference in Hb and Alb, but the lymphocyte count was significantly lower in patients with PCF.

Abstract
The incidence of laryngeal tuberculosis has steadily increased due to rising prevalence of HIV infection, immunosuppressive diseases and treatments, and the emergence of multidrug-resistant organisms and atypical mycobacteria. We report on a woman with a unique presentation of laryngeal tuberculosis mimicking lymphoma to remind clinicians that the diagnosis of laryngeal tuberculosis merits awareness and that delay in diagnosis poses a serious threat to the patient due to delayed treatment and further complications.

Abstract
Posttreatment detection of residual/recurrence disease in the head and neck cancers is not an easy task. Treatment induces changes create difficulties in diagnosis on conventional imaging (computed tomography [CT], magnetic resonance imaging) as well as macroscopic inspection (direct laryngoscopy). Hence, we evaluate the diagnostic performance of contract-enhanced F-18 fluorodeoxyglucose positron emission tomography (FDG PET)/CT in restaging of laryngeal carcinoma Postchemotherapy-surgery and/or radiation therapy. We retrospectively analyzed patients of carcinoma larynx (n = 100) who has completed treatment and were referred for FDG PET/CT. Two reviewers performed image analysis to determine recurrence at primary site and/lymph nodes and distant metastases. Receiver operating characteristic (ROC) was used to determine the maximum standardized uptake value (SUVmax) cut off for disease detection. Histopathological examination and clinical or imaging follow-up were taken as gold standard for recurrence. One hundred laryngeal carcinoma patients with mean age of 57.2 years (range of 40–76) were included in the present study. Among the 100 patients, 96 were male and remaining 4 were female. The average interval between completion of treatment and FDG PET/CT scan was 8.5 months (minimum 6 months). Of the 100 patients, FDG PET/CT detected FDG avid lesions in 66 patients. Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of FDG PET/CT for residual/recurrence disease detection was 90.3%, 73.7%, 84.8%, 82.3%, and 84.0%, respectively (P < 0.05). In addition, in 10 patients, metachronous primaries were detected (lung-4, thyroid-2, tongue, colon, esophagus, and lymphoma-one each). On ROC curve analysis, SUVmax >6.1 had sensitivity and specificity of 80.6% and 94.7% respectively for detection of recurrent/metastatic disease. FDG PET/CT demonstrates high diagnostic accuracy for detection of residual/recurrent disease in treated laryngeal cancer patients and our findings suggest that this imaging modality should be the first-line diagnostic investigation in this cohort of patients.
