Abstract
Neurensin-2 (NRSN2) performs a pro-carcinogenic function in multiple cancers. However, the function of NRSN2 in HPV-infected laryngeal carcinoma (LC) remains unclear. HPV transfection was performed in LC cells. The mRNA and protein levels were monitored using RT-qPCR, immunoblotting, and IF. Cell viability and proliferation were found using the CCK-8 assay and Edu staining. Cell invasion, migration, and apoptosis were probed using the Transwell, wound healing, and flow cytometry, respectively. The autophagosome was observed using TEM. NRSN2 was overexpressed in HPV-transfected LC cells. Inhibition of NRSN2 restrained the autophagy and malignant behavior of HPV-transfected LC cells. Meanwhile, the inhibition of AMPK/ULK1 pathway limited the increased autophagy of HPV-transfected LC cells caused by NRSN2 overexpression. Furthermore, NRSN2 knockdown inhibits autophagy by suppressing AMPK/ULK1 pathway, thereby restraining the malignant behavior of HPV-transfected LC cells. Our research confirmed that HPV transfection increased the autophagy and malignant behavior of LC cells by regulating the NRSN2-mediated activation of the AMPK/ULK1 pathway, offering a new target for cure of LC.

Abstract
OBJECTIVES The aim of this study was to investigate the degree of discrepancy between the clinical and pathological staging of laryngeal carcinoma, and the potential impact of this discrepancy on the outcomes and prognosis. METHODS This study was conducted on 127 patients who underwent total laryngectomy over five years (October 2016-October 2021). Data collected from pretherapeutic clinical staging regarding the extent of the tumor affection of different laryngeal subsites was compared to the postsurgical pathological assessment. RESULTS Overall, 12 out of 127 patients (9.4%) in the current study, were clinically over-staged from T3 to T4 due to radiological diagnosis of tumor infiltration of laryngeal cartilages that proved pathologically to be free of tumor. Additionally, discordance in the N stage was found in 12.6% (n = 16). However, stage discrepancy did not have a significant impact on the prognosis and survival. CONCLUSION Discordance between clinical and pathological TNM staging of laryngeal carcinoma may affect the decision making and the choice of the treatment options. Some improvement can be probably achieved with advancements and higher accuracy of the preoperative diagnostic tools.

Abstract
Introduction Although stereotactic ablative radiotherapy (SABR) has advance to standard-of-care for many different indications like lung and liver malignancies, it still remains in its infancy for treating head and neck cancer. Nevertheless there is a growing body of experience and evidence, which is summarized in this review Methods A thorough search of the literature was performed and critically reviewed both for SABR as a primary treatment as well as for treating locoregionally recurrent disease in a pre-irradiated field. Results There exist only few prospective data published so far for treating head and neck cancer with SABR. In the primary situation especially implementing SABR as a boost after definitive radiotherapy or a single-modality for locally limited, small glottic cancer appear promising. On the other hand, SABR can be a useful modality for treating local recurrence in a pre-irradiated field. However, caution is needed in the case of proximity to a pre-irradiated carotid artery or other serial organs at risk. Usually only limited gross volumes are treated with 3-6 fractions every other day and a cumulative dose of 24-44 Gy in dedicated radiosurgery platforms or modern linacs with the possibility of online image-guidance and adequate immobilsation. Conclusions SABR is an innovative, effective and promising treatment modality for small targets, especially in near proximity to organs at risk or in a pre-irradiated region. Prospective trials are further needed for this technique to become standard-of care.

Abstract
PURPOSE To establish two nomograms to quantify the risk of lung metastasis (LM) in laryngeal carcinoma (LC) and predict the overall survival of LC patients with LM. METHODS Totally 9515 LC patients diagnosed histologically from 2000 to 2019 were collected from the Surveillance, Epidemiology, and End Results database. The independent diagnostic factors for LM in LC patients and prognostic factors for LC patients with LM were identified by logistic and Cox regression analysis, respectively. Nomograms were established based on regression coefficients and evaluated by receiver operating characteristic curve, calibration curves, and decision curve analysis. RESULTS Patients with supraglottis, higher pathological grade, higher N stage, and distant metastasis (bone, brain, or liver) were more likely to have LM (P < 0.05). Chemotherapy, surgery and radiotherapy were independent factors of the overall survival of LC patients with LM (P < 0.05). The area under curve of diagnostic nomogram were 0.834 and 0.816 in the training and validation cohort respectively. For the prognostic nomogram, the area under curves of 1-, 2-, and 3-years were 0.735, 0.734, and 0.709 in the training cohort and 0.705, 0.803, and 0.809 in the validation cohort. The calibration curves and decision curve analysis indicated good performance of the nomograms. CONCLUSION Distant metastasis (bone, brain, or liver) and N stage should be considered for prediction of LM in LC patients. Chemotherapy is the most significant influencing prognostic factor improving the survival of LC patients with LM. Two nomograms may benefit for providing better precautionary measures and treatment decision.

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
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.

Abstract
Depending on the source of the blastophore, there are various subtypes of laryngeal cancer, each with a unique metastatic risk and prognosis. The forecasting of their prognosis is a pressing issue that needs to be resolved. This study comprised 5953 patients with glottic carcinoma and 4465 individuals with non-glottic type (supraglottic and subglottic). Five clinicopathological characteristics of glottic and non-glottic carcinoma were screened using univariate and multivariate regression for CoxPH (Cox proportional hazards); for other models, 10 (glottic) and 11 (non-glottic) clinicopathological characteristics were selected using least absolute shrinkage and selection operator (LASSO) regression analysis, respectively; the corresponding survival models were established; and the best model was evaluated. We discovered that RSF (Random survival forest) was a superior model for both glottic and non-glottic carcinoma, with a projected concordance index (C-index) of 0.687 for glottic and 0.657 for non-glottic, respectively. The integrated Brier score (IBS) of their 1-year, 3-year, and 5-year time points is, respectively, 0.116, 0.182, 0.195 (glottic), and 0.130, 0.215, 0.220 (non-glottic), demonstrating the model's effective correction. We represented significant variables in a Shapley Additive Explanations (SHAP) plot. The two models are then combined to predict the prognosis for two distinct individuals, which has some effectiveness in predicting prognosis. For our investigation, we established separate models for glottic carcinoma and non-glottic carcinoma that were most effective at predicting survival. RSF is used to evaluate both glottic and non-glottic cancer, and it has a considerable impact on patient prognosis and risk factor prediction.

Abstract
OBJECTIVE In this study, we analyzed the correlation between the preoperative plasma lycopene levels, postoperative adverse complications of chemoradiotherapy, and nutritional risk scores in patients with laryngeal carcinoma. METHODS A total of 114 patients with laryngeal carcinoma and 114 healthy respondents were enrolled in this study. The patients with laryngeal carcinoma were divided into two groups: 62 patients with laryngeal carcinoma, with an NRS2002 score higher than 3 points and whose diet contained lycopene, were enrolled in the observation group, and 52 patients with laryngeal carcinoma during the corresponding time period, whose diet did not contain lycopene, were enrolled in the reference group. The immune indexes (CD4 + , CD8 + , IGA, IGM, IGG), nutritional indexes (albumin, prealbumin, transferrin), and postoperative adverse complications of chemo-radiotherapy in the two groups were recorded. RESULTS The lycopene levels were lower in patients with advanced tumor stage (III and IV). The diagnosis threshold of the plasma lycopene level for laryngeal carcinoma was 0.503 μmol/L. The area under the curve for plasma lycopene levels in cancer diagnosis was 0.96, with a clinical specificity of 0.943 and a sensitivity of 0.859. There was a significant negative correlation between the plasma lycopene levels and Nutrition Risk Screening (NRS) 2002 score (R2 = - 0.523, P < 0.001), which was related to the increase in NRS-2002 scores and nutritional hazards in patients with laryngeal carcinoma. The observation group showed a significant increase in nutritional and immune indices, as compared to the reference group, as well as a lower incidence of severe and serious adverse reactions to chemo-radiotherapy. Lycopene supplementation, tumor stage, NRS-2002 scores, nutritional and immune indices were all significant predictors of postoperative severe and serious adverse complications of chemoradiotherapy. CONCLUSION Progression of laryngeal carcinoma and severity of the side effects of the adverse complications of chemo-radiotherapy are related to the levels of lycopene.

Abstract
Oridonin is the main bioactive component of Rabdosia rubescens, and its anticancer activity has been reported in a variety of cancers. However, the molecular mechanism of oridonin in laryngeal carcinoma remains unclear. In the present study, the cytotoxic effect of oridonin on laryngeal carcinoma Hep-2 and TU212 cell lines were initially detected by modified MTT assay. The results showed that oridonin had a dose-dependent anti-proliferative effect on laryngeal carcinoma Hep-2 and TU212 cells. Next, we found that oridonin significantly inhibited the migration and invasion of human laryngeal carcinoma Hep-2 and TU212 cell lines by wound healing assay and transwell assay. Subsequently, the results of quantitative real-time PCR assay and western blotting assay confirmed that oridonin upregulated the expression of E-cadherin while downregulated the expression of N-cadherin in a concentration-dependent manner at mRNA and protein levels. In addition, phosphorylation levels of liver kinase B1 (p-LKB1) and AMP-activated protein kinase (p-AMPK) were also elevated upon oridonin treatment. To further verify the role of LKB1/AMPK signaling pathway in laryngeal carcinoma, overexpression of LKB1 was constructed by plasmid transfection. The data exhibited that overexpression of LKB1 could further reinforce the increase of E-cadherin level and decrease of N-cadherin level mediated by oridonin. Additionally, AMPK inhibitor compound C could reverse anti-metastatic effect of oridonin on laryngeal carcinoma, and antagonise EMT expression. In contrast, AMPK activator AICAR presented the opposite effect. In conclusion, our study revealed that oridonin could remarkably reverse the epithelial-mesenchymal transition of laryngeal carcinoma by positively regulating LKB1/AMPK signaling pathway, which suggested that oridonin may be a potential candidate for the treatment of laryngeal carcinoma in the future.

Abstract
RATIONALE AND OBJECTIVES Accurate staging of laryngeal carcinoma can inform appropriate treatment decision-making. We developed a radiomics model, a deep learning (DL) model, and a combined model (incorporating radiomics features and DL features) based on the venous-phase CT images and explored the performance of these models in stratifying patients with laryngeal carcinoma into stage I-II and stage III-IV, and also compared these models with radiologists. MATERIALS AND METHODS Three hundreds and nineteen patients with pathologically confirmed laryngeal carcinoma were randomly divided into a training set (n = 223) and a test set (n = 96). In the training set, the radiomics features with inter- and intraclass correlation coefficients (ICCs)> 0.75 were screened by Spearman correlation analysis and recursive feature elimination (RFE); then support vector machine (SVM) classifier was applied to develop the radiomics model. The DL model was built using ResNet 18 by the cropped 2D regions of interest (ROIs) in the maximum tumor ROI slices and the last fully connected layer of this network served as the DL feature extractor. Finally, a combined model was developed by pooling the radiomics features and extracted DL features to predict the staging. RESULTS The area under the curves (AUCs) for radiomics model, DL model, and combined model in the test set were 0.704 (95% confidence interval [CI]: 0.588-0.820), 0.724 (95% CI: 0.613-0.835), and 0.849 (95% CI: 0.755-0.943), respectively. The combined model outperformed the radiomics model and the DL model in discriminating stage I-II from stage III-IV (p = 0.031 and p = 0.020, respectively). Only the combined model performed significantly better than radiologists (p < 0.050 for both). CONCLUSION The combined model can help tailor the therapeutic strategy for laryngeal carcinoma patients by enabling more accurate preoperative staging.

Abstract
A growing body of evidence suggests that miR-5189-3p plays a critical role in multiple diseases. This study aimed to investigate the function of miR-5189-3p in laryngeal squamous cell carcinoma (LSCC) and explore its underlying mechanisms. qRT-PCR was designed to determine the expression levels of miR-5189-3p and eukaryotic translation initiation factor 5A2 (EIF5A2), while CCK-8 assay was performed to measure the effects of miR-5189-3p on cell proliferation. Transwell assay was performed to evaluate cell invasion as well as migration, and wound healing assay was applied to demonstrate cell migratory ability. Target gene prediction and luciferase reporter assay were developed to screen the possible target gene of miR-5189-3p, and Western blot was designed to measure EIF5A2 protein expression. MiR-5189-3p was down-regulated in LSCC tissues and cell lines. Up-regulation of miR-5189-3p notably inhibited cell proliferation, invasion, and migration in HEP2 and FADU cells. EIF5A2 was the potential downstream gene of miR-5189-3p, and overexpression of miR-5189-3p apparently reduced EIF5A2 expression. Moreover, reintroduction of EIF5A2 rescued the tumor suppressive effects of miR-5189-3p. MiR-5189-3p functions as a tumor inhibitor in LSCC progression via directly regulating EIF5A2 and may be a potential therapeutic target for LSCC.

Abstract
Aims: This study aims to make a comparative analysis of disease-free survival (DFS) and overall disease-specific survival (OS) in patients with laryngeal carcinoma. Materials and methods: The study was designed retrospectively. Sixteen patients with postoperative PSM and 30 with negative surgical margins (NSM) were included. Survival analysis and Long-Rank comparisons was performed for DFS and OS between groups. Results: PSM was a significant independent risk factor for loco-regional recurrence and disease-related mortality (p = 0.004, HR: 1.6, p = 0.002, HR: 3.2, respectively). DFS and OS were significantly longer in NSM group (p = 0.001 and 0.003, respectively). For PSM group, 2- and 5-year DFS rates were 57%; OS rates were 80% and 34% respectively. In NSM group, 2- and 5-year DFS rates were 96% and 83%; OS rates were found to be 96%. Conclusion: PSM had significant relation with poor prognosis.

Abstract
Background: Laryngeal squamous cell carcinoma (LSCC) is a malignant tumor of the head and neck, the exact mechanism of which has not been explored. Methods: By analyzing the GEO data, we found the highly methylated and low expression gene ZNF671. The expression level of ZNF671 in clinical samples was verified by RT-PCR, western blotting and methylation-specific PCR. The function of ZNF671 in LSCC was detected by cell culture and transfection, MTT, Edu, TUNEL assays and flow cytometry analysis. The binding sites of ZNF671 to MAPK6 promoter region were detected and verified by luciferase reporter gene and chromatin immunoprecipitation. Finally, the effect of ZNF671 on LSCC tumors was tested in vivo. Results: In this study, by analyzing GEO data GSE178218 and GSE59102, we found that zinc finger protein (ZNF671) expression was decreased, and DNA methylation level was increased in laryngeal cancer. Moreover, the abnormal expression of ZNF671 was associated with poor survival prognosis of patients. In addition, we found that overexpression of ZNF671 could inhibit the viability, proliferation, migration and invasion of LSCC cells, while promoting cell apoptosis. In contrast, the opposite effects were observed after knockdown of ZNF671. Through the prediction website and chromatin immunoprecipitation and luciferase reporter experiments, it was found that ZNF671 could bind to the promoter region of MAPK6, thereby inhibiting the expression of MPAK6. In vivo experiments confirmed that overexpression of ZNF671 could inhibit tumor growth. Conclusion: Our study found that ZNF671 expression was down-regulated in LSCC. ZNF671 up-regulates the expression of MAPK6 by binding to its promoter region, thus participating in cell proliferation, migration and invasion in LSCC. Our study may provide new ideas for early prediction and treatment of LSCC.

Abstract
PURPOSE To explore the prognostic factors and the optimal treatment modalities for patients with stage IVA laryngeal squamous cell carcinoma (LSCC), so as to improve the survival rate of patients. METHODS Patients with stage IVA LSCC between 2004 and 2019 were selected from the Surveillance, Epidemiology, and End Results (SEER) database. We used competing risk models to build nomograms for predicting cancer-specific survival (CSS). The effectiveness of the model was assessed using the calibration curves and the concordance index (C-index). The above results were compared with the nomogram established by Cox regression analysis. The patients were grouped into low-risk and high-risk groups by competing risk nomogram formula. And the Kaplan-Meier (K-M) method and log-rank test were used to make sure that these groups had a survival difference. RESULTS Overall, 3612 patients were included. Older age, black race, a higher N stage, a higher pathological grade, and a larger tumor size were independent risk factors for CSS; married marital status, total/radical laryngectomy, and radiotherapy were protective factors. The C-index was 0.663, 0.633, and 0.628 in the train set and 0.674, 0.639, and 0.629 in the test set of the competing risk model, and 0.672, 0.640, and 0.634 in the traditional Cox nomogram for 1, 3, and 5 years. In overall survival and CSS, the prognosis of the high-risk group was poorer than that of the low-risk group. CONCLUSION For patients with stage IVA LSCC, a competing risk nomogram was created to help screen risk population and guide clinical decision-making.

Abstract
BACKGROUND Although total laryngectomy is the standard treatment for advanced laryngeal cancer, the significance of elective neck dissection (END) for N0 laryngeal cancer remains unclear in Japan, which is an aging society. METHODS We conducted a retrospective nationwide observational study on patients with T3-T4N0 laryngeal squamous cell carcinoma treated with curative total laryngectomy from 2011 to 2018 in Japan. RESULTS A total of 1,218 patients were analyzed. The median patient age was 72 years, with 735 cases of T3N0 and 483 cases of T4N0. END was performed on the affected side in 850 patients (70%) and on the contralateral side in 502 patients (41.2%). END on the affected side was omitted in patients aged > 80 years (40.4%) and in patients with an advanced performance status. The occult lymph-node metastasis rate did not differ by age (18.8%-19.6%); it tended to increase chronologically from 2011 (11.1%) and was higher in cT4a (22.5%) and pT4a (24.3%) cases. In this study, coherent clinical information and follow-up data were available for 252 patients. Both univariate and multivariate analyses showed no significant prognostic factors for overall survival or recurrence-free survival for either affected or contralateral END. Older age and subglottic location were poor prognostic factors, but death due to factors other than laryngeal cancer could not be ignored in older patients. CONCLUSION Omission of END during laryngectomy for T3-T4N0 laryngeal cancer is acceptable for older patients who want their operation to be completed in a short time.

Abstract
The incidence of laryngeal carcinoma accounts for 1 to 5% of systemic malignancies and ranks second among head and neck malignancies. Screening more effective targets are meaningful for the treatment of laryngeal carcinoma. The purpose was to research the action of miR-21-5p in the occurrence of laryngeal carcinoma. Genecards combined with g:profiler was used for cluster analysis to predict gene-related miRNAs. Q-PCR assay was performed for measuring the level of miR-21-5p and Kruppel-like factor 6 (KLF6). miR-21-5p-mimic, miR-21-5p-inhibitor and sh-KLF6 were transfected using LipofectamineTM 2000. Both CCK-8 and EdU experiments were undertaken to detect cell proliferation ability. Western blot was used to detect apoptosis and epithelial-mesenchymal transition (EMT) related proteins. Wound healing assay and transwell assay were undertaken for migration and invasion, respectively. Three online software (ENCORI, miRWalk, and miRDB) were applied to screen the downstream of miR-21-5p. At the same time, a dual-luciferase reporter experiment was processed to verify the binding. Finally, a rescue experiment was applied to reveal the mediating role of miR-21-5p and KLF6. MiR-21-5p expressed highly in laryngeal carcinoma tissues and cell lines. Knockdown of miR-21-5p reduced the EMT, while enhancing apoptosis of laryngeal carcinoma cell lines. MiR-21-5p targeted KLF6 with negative relationships. The rescue assay results confirmed that sh-KLF6 rescued the action of miR-21-5p knockdown in developing laryngeal carcinoma cells. MiR-21-5p promotes the occurrence and development of laryngeal cancer by targeting KLF6. This finding may provide new insights into miRNA as a biomarker for diagnosing and treating laryngeal carcinoma in the future.

Abstract
PURPOSE To developed a model to screen distant metastatic laryngeal carcinoma (DMLC) patients who would benefit from the primary tumor resection. METHODS The propensity score matching (PSM) was utilized to avoid disproportionate distributions of the confounding factors. We hypothesized that patients who underwent surgery would benefit from surgery by having a longer median cancer-specific survival (CSS) than patients without surgery. Multivariable Cox model was used to explore the independent factors of CSS and overall survival (OS) among PSM population. We used these factors to construct a nomogram to identify surgery benefit patients. The predictive performance and clinical practicability of the nomogram were determined by area under the curve (AUC), calibration curve, and decision curve. RESULTS The CSS and OS for patients who received primary tumor resection were significantly longer than those without resection (median CSS: 19 months vs. 10 months, P = 0.009; median OS: 21 months vs. 10 months, P = 0.001). The nomogram displayed a good degree of discrimination and calibration. The mean AUC of the nomogram was 0.70 (95% confidence interval [CI] 0.66-0.76) through threefold cross-validation. CONCLUSIONS A predictive model was established and might be used to screen the optimal candidates for primary tumor surgery in DMLC patients.

Abstract
There is a need for novel prognostic parameters in assessing laryngeal squamous cell carcinoma (LSCC). Tumor budding is an instrumental parameter, which has hardly been studied before in this organ. This study aimed to assess tumor budding in LSCCs with routine hematoxylin and eosin (H&E) stain as well as cytokeratin (CK) immunohistochemistry (IHC). Objectives were to compare the effectiveness of both these methods to assess tumor budding, to investigate the association of tumor budding and clinicopathologic features, and to determine the prognostic significance of tumor budding in LSCCs. Fifty laryngectomy specimens were included. Tumor budding was counted (20x) on slides stained with IHC-CK, and highest count per slide was noted. The cases were classified as positive (> 1 buds) or negative (no buds present). The budding index was categorized as low (< 5 buds) or high (> 5 buds). Tumor budding on H&E was absent, low and high grade in 28%, 30% and 42% cases respectively, when compared to CK-IHC in 17%, 24% and 59% of cases, respectively. Presence of lymphoplasmacytic infiltration significantly correlated with tumor budding and higher grade. Transglottic location of tumor and pT stage was associated with high budding. Presence of lymphoplasmacytic infiltrate significantly correlated with worse prognosis. Tumor budding, an easily assessable, inexpensive histopathologic parameter has seldom been studied in LSCCs. Presence of lymphoplasmacytic infiltrate in routine preoperative biopsy reporting could be useful in prognostication. CK-IHC is helpful to detect especially cases with low-grade tumor budding.

Abstract
Objective Laryngeal cancer is a common malignancy in otorhinolaryngological head and neck surgery, accounting for approximately one-third of all head and neck malignancies. Terahertz time-domain spectroscopy (THz-TDS) has recently been found to be useful for the detection of tumors. This study was conducted to investigate the application of THz-TDS in the diagnosis of pathological resection margins of laryngeal cancer. Methods Fresh laryngeal cancer tissues from 10 patients with laryngeal cancer were extracted, and after simultaneous HE staining and terahertz imaging, the tumor area, paracancerous area, and normal tissue area of each laryngeal cancer tissue sample were located under a microscope according to the pathological results of HE staining. Results The shape contours of the tumor region revealed by terahertz imaging maps and HE staining were similar. In the terahertz spectrum in the frequency range of 0.5–1.9 THz, both the absorption coefficient and refractive index values followed the order tumor > para cancer > normal tissue, with statistically significant differences (P < 0.01). When the terahertz frequency was 1.5 THz, the absorption coefficient of terahertz light waves by laryngeal cancer tissue and the percentage of nuclei showed an extremely high positive correlation (P < 0.01, r = 0.971). In the frequency ranges of 0.5–1.2 THz and 1.6–1.9 THz, the absorption coefficients of the highly differentiated group were higher than those of the moderately differentiated group. In the frequency range of 1.2–1.6 THz, the results were reversed, with statistically significant differences (P < 0.05). In the frequency range of 0.5–1.9 THz, the highly differentiated group had a higher refractive index than the moderately differentiated group, with a statistically significant difference (P < 0.05). Conclusions THz-TDS can be used to determine the pathological margins of laryngeal cancer based on the absorption coefficient and refractive index, and the magnitudes of the absorption coefficient and refractive index are related to the percentage of nuclei. The degree of differentiation of laryngeal cancer tissue can be assessed by THz-TDS. The study shows that the terahertz time-domain system is promising for applications in the diagnosis of laryngeal cancer, especially for the more accurate identification of intraoperative margins.

Abstract
Pharyngocutaneous fistula (PCF) after laryngectomy occurs when there is a failure in the pharyngeal repair resulting in a salivary leak (Dedivitis et al. in Acta Otorhinolaryngol Ital 27(1):2-5, 2007). In the post-operative period this complication is not only a challenge to the surgeon but also distressing to the patient and his family. We conducted a retrospective cum prospective study, to research the effect of starting prophylactic glycopyrrolate intravenous injection in total laryngectomy. Fifty patients underwent total laryngectomy with modified radical neck dissection over a period of 5 years by the trainee otolaryngologists. Of these 25 patients were started on glycopyrrolate for 7 post-operative days. And 25 control patients, who were not given glycopyrrolate. All the patients were observed for evidence of PCF. Of the total 50 patients, only 1 patient in study group and 12 patients in the control group developed PCF. This was statistically significant (p value 0.0039). Tumor stage, site, and gender were found to have no statistically significant correlation with development of PCF. The prophylactic administration of glycopyrrolate was found to reduce the odds of development of PCF in total laryngectomy cases. There was associated blurring of vision and constipation amongst the cases subjects, which was only transient with complete recovery on cessation of drug.

Abstract
OBJECTIVES Pharyngocutaneous fistula (PCF) is a devastating complication of laryngectomy. Different factors, principally previous irradiation, increases the risk for PCF formation. The current study objectives is to investigate the potential negative effect of re-irradiation on fistula development. Materilas and methods This is a single, referral, medical center retrospective, cohort study, conducted between the years 2011-2021. Electronic medical files, surgical notes, laboratory records and radiation plan (dose and time interval in case of re-irradiation) were examined. Main outcomes and measures Risk and predictors associated with PCF formation. Risk and severity of PCF in the setting of re-irradiation. RESULTS Overall, 27 laryngectomized patients were investigated, of whom 21 patients had single radiation (pre or post-operative radiation) and the other 6 patients had two radiation treatments (before and after laryngectomy). The fistula rate was 33.33% (7/21) in the single radiation compared (p = 0.14) to 66.66% (4/6) in the re-irradiation group of patients (including late-onset fistulas). All single radiation PCF were self-limited, whereas, 3 out of 4 fistulas in the re-irradiation group were longstanding or permanent. In the re-irradiation group of patients, a shorter time interval between the first and second radiation treatments was demonstrated among those with fistula formation compared to patients with uneventful laryngectomy (p = 0.08). CONCLUSION Re-irradiation and especially a brief interval between the radiation treatments is associated with a severe PCF.

Abstract
OBJECTIVES This study aimed to examine the relationship between checkpoint receptors (PD-1, PD-L1, PD-L2, CTLA-4) and lymphoid infiltration level (TILs) with prognostic features of patients with laryngeal squamous cell carcinoma (LSCC). METHODS A retrospective study was designed at a tertiary referential university hospital between April 2008 and December 2020. The surgical specimen of the patients who met the eligibility criteria were re-examined histopathological, sociodemographic, clinical, pathological, and follow-up findings of patients were determined. The impact of PD-1, PD-L1, PD-L2, CTLA4, and TILs levels for the presence of cancer recurrence, disease-specific mortality, overall survival (OS), disease-free survival (DFS) was investigated. RESULTS Forty-five patients with LSCC were included in the study. The mean follow-up period was 48.3 ± 14.3 months (min: 36, max 84). TILs scores were detected significantly lower in patients with distant metastasis and recurrence (p = 0.046 and 0.010). Also, only TILs was a significant risk factor for recurrence and survival among the PD-1, PD-L1, PD-L2, CTLA-4, and TILs (HR = 0.217 CI: 0.070-0.679, p = 0.009 and HR = 0.566, CI: 0,321-980, p = 0.048). Similarly, for the TILs score: > 1 was significant for DFS. (Long-Rank = 0.009). The examined markers and TILs scores were not a significant predictive factor for OS. CONCLUSION An increase in TILs density in LSCCs is associated with a better prognosis. However, PD-1, PD-L1, PD-L2, CTLA-4 could not be associated with prognosis. Controlled studies combined with immunotherapy treatment results are needed to reveal their role as a marker and prognostic factor of the anti-tumor immune response.

Abstract
OBJECTIVES The interaction between tumor cells and stroma is critical in tumorigenesis, tumor neo-angiogenesis and cancer progression. The aims of this study were to: (i) evaluate the concordance between tumor-stroma ratio (TSR) and microvascular density (MVD) on paired biopsy and surgical specimens of laryngeal carcinoma (LSCC); (ii) investigate the association of TSR with angiogenesis (CD105- and CD31-assessed MVD); (iii) assess the prognostic role of TSR and MVD evaluated on preoperative biopsies and paired surgical specimens. METHODS TSR, CD105- and CD31-assessed MVD were analyzed in paired biopsies and surgical specimens of 43 consecutive cases. RESULTS TSR showed good agreement between biopsies and surgical specimens (AC1 statistic: 0.7957). In biopsies, TSR low/stroma-rich cases showed higher CD105-assessed MVD (p = 0.0380). In surgical specimens both median CD105- and CD31-assessed MVD were significantly higher in TSR low/stroma-rich than in TSR high/stroma-poor patients (p = 0.0089 and p = 0.0391). In the univariate Cox's model, TSR predicted disease-free survival (DFS) in both biopsies and surgical specimens (p = 0.0003 and p = 0.0002). DFS was associated with CD105- and CD31-assessed MVD in biopsies (p < 0.0001 for both) and surgical specimens (p < 0.0001 for both). Considering biopsies, the multivariate analysis found both TSR (p = 0.0032; HR = 6.112, 95%CI: 1.833-20.378) and CD105-assessed MVD (p = 0.0002; HR = 1.201, 95%CI: 1.090-1.322) as DFS predictor. In paired surgical specimens, both TSR (p = 0.0074; HR = 6.137, 95%CI: 1.626-23.172) and CD105-assessed MVD (p = 0.0005; HR = 1.172 95 %CI 1.071-1.282) retained their significance in multivariate analysis. CONCLUSIONS If confirmed by large prospective studies, TSR and MVD could be proposed as prognostic biomarkers of LSCC for a possible treatment intensification or targeted therapy.

Abstract
This study aimed to develop a multidimensional model for the evaluation of substitution voicing (SV) after laryngeal oncosurgery. The study group consisted of 121 adult male individuals: 59 patients with SV after laryngeal oncosurgery (endolaryngeal cordectomy, partial laryngectomy, total laryngectomy with tracheoesophageal prosthesis) and 62 healthy controls. A multidimensional protocol for the assessment of SV included, 1) self-reported speech evaluation with a short version of the Speech Handicap Index, 2) auditory-perceptual assessment, and 3) acoustic speech analysis using AMPEX® (Auditory Model Based Pitch Extractor) software. Moderate correlations were observed between parameters from self-reported auditory-perceptual and acoustic speech analysis domains. The multidimensional Substitution Voicing Index (SVI), including markers from these domains, was elaborated by using linear stepwise regression to determine the optimal set of parameters for categorising SV patients. The lowest mean SVI score was revealed in the control subgroup corresponding to the normal speech, followed by cordectomy subgroup and partial laryngectomy subgroup. The highest mean SVI score was revealed in the total laryngectomy subgroup, reflecting the most severely deteriorated quality of SV. One-way analysis of variance identified statistically significant differences between the mean SVI scores in separate subgroups. The results demonstrated the potential benefits of the SVI for a multidimensional evaluation of SV in patients after laryngeal oncosurgery.

Abstract
Could primary chemoradiotherapy (pCRT) possibly be viewed as an alternative standard therapy to upfront total laryngectomy (TL)? According to the new German S3 guideline, despite higher rates of local recurrence, there would be no survival disadvantage and salvage surgery would be a curative option. In several large database studies and case series, statistically significant survival disadvantages of more than 30% between pCRT and TL have been reported for T4 laryngeal cancer. According to the literature, the success rate of salvage TL for T4 laryngeal cancer is only about 25-50%. Larynx preservation (LP) studies which could qualify the recommendation of pCRT as an alternative standard therapy to TL in T4 carcinomas should 1) evaluate T4a cancers within the T4 category; 2) perform subgroup analysis of laryngeal and hypopharyngeal cancers; 3) be sufficiently highly powered; 4) provide long-term outcomes of at least 5 years; 5) with oncological and 6) functional outcomes (duration of the need for tracheostomy and/or feeding tube dependency; necessity and success of salvage laryngectomies). 7) Specification of the criteria of the respective T4 classification (invasion through the outer cortex of the cartilage, or infiltration of which extralaryngeal structures) and 8) evaluation of pretreatment laryngeal function (at least: tracheostomy, feeding tube dependency). Collection of all the aforementioned data of T4 patients treated with pCRT in a large prospective observational cohort study in German-speaking countries is suggested. In case of rejection of TL by T4 laryngeal cancer patients, differentiation between primary spontaneous reluctance and a definitive, carefully considered decision is important. This distinction should be achieved by sensitive discussions. Not only oncological but also functional outcome probabilities should be included in the overall decision-making process.

Abstract
BACKGROUND By today's standard, the optimal treatment of every individual tumor patient is discussed and determined in an interdisciplinary tumor board. According to the new S3 guidelines, larger volume T3 laryngeal cancers which are no longer safely resectable with larynx-sparing surgery are ideal candidates for a larynx preservation approach using primary chemoradiation (pCRT). So far, no clear criteria have been defined under what circumstances primary radiotherapy alone (pRT) might be acceptable in case chemotherapy (CT) is prohibited or in what cases, even in T3, upfront total laryngectomy with risk-adapted adjuvant treatment (TL±a[C]RT) should be recommended. METHOD The literature was searched for parameters chosen as criteria for an inclusion in the surgical rather than the conservative arm in non-randomized LP studies or which proved to be significant prognostic markers after conservative treatment. Development of a counselling tool for therapeutic decision making. RESULTS Significant prognostic markers were tumor volume (< 3.5 ccm/< 6 ccm vs. 6-12 ccm vs. > 12 ccm), presence and kind of vocal cord fixation (none vs. Succo I/II vs. Succo III/IV), extent of cartilage infiltration (none vs. minimal vs. multiple/gross), nodal status (N0‑1 vs. N2-3), and laryngeal dysfunction (pretreatment necessity of feeding tube or tracheostomy). CONCLUSION For T3 laryngeal cancers, pRT could be acceptable when the tumor volume is < 3.5 ccm for glottic and < 6 ccm for supraglottic tumors and there are no further risk factors. pCRT can be regarded as the standard for LP for tumors between 6 ccm and 12 ccm, vocal cord fixation Succo pattern I/II, only minimal cartilage infiltration and a high nodal burden. For tumor > 12 ccm, vocal cord fixation Succo pattern III/IV, gross or multiple cartilage infiltration or clinically relevant laryngeal dysfunction, upfront TL±a[C]RT should be considered.

Abstract
Backgroud/Objectives: Transoral laser laryngeal microsurgery (LTLM) has been widely used in the treatment of early-stage glottic laryngeal squamous cell carcinoma (LSCC) for the past few decades. Although T stage, tumor grade, anterior commissure involvement, type of cordectomy, positive surgical margin, and postoperative additional therapies were accused as the prognostic factors for recurrence, there is still controversy about these data in the literature. The purpose of this study was to evaluate the oncological results of our patients with early glottic LSCC treated with LTLM as a single-modality therapy in a single-center study. METHODS Patients with early-stage (Tis-1-2/N0) glottic LSCC who underwent LTLM as a primary treatment from 2011 to 2019 were retrospectively reviewed. The clinicopathological factors and oncologic outcomes were analyzed. RESULTS One hundred and sixty-one patients were enrolled in this study. The 5-year overall (OS), disease-specific (DSS), disease-free (DFS), and laryngectomy-free survival rates were 84.5%, 97.9%, 79.2%, and 93.5%, respectively. The most common stage, histopathological type, and type of endoscopic cordectomy were T1 stage, well-differentiated cancer, and type 2 cordectomy, respectively. A positive surgical margin was defined in 20 (12.4%) patients. There was a significant relationship between histopathological grade and positive surgical margins (p = 0.038). OS and DSS rates of "wait and see" modality were lower, while DFS of radiotherapy was lower than that of other treatment modalities in patients with positive surgical margins, but the differences were not statistically significant. Nineteen (11.8%) patients had a recurrence. DSS was statistically significantly lower in patients with recurrence (p < 0.001). CONCLUSION The results of our study showed that anterior commissure involvement, surgical margin positivity, and higher T stage statistically did not reduce survival rates in early-stage LSCC patients treated with LTLM. As the histopathological grade of the tumor worsens, the risk of surgical margin positivity increases. RT may have a negative effect on recurrence and organ preservation in the additional treatment of patient with positive surgical margins.

Abstract
The Radiation Therapy Oncology Group 91-11 trial and US Veterans Affairs trial revolutionized the way locally advanced laryngeal cancers are treated. Adjuvant therapies exist aimed toward laryngeal preservation using docetaxel, cisplatin, and fluorouracil. Cetuximab is a cornerstone of treatment due to the large role of epidermal growth factor receptor in laryngeal and hypopharyngeal carcinomas. In addition, the immune system is vital in the prevention of recurrence, and various immunomodulators against programmed cell death receptor 1 are being investigated. Multidisciplinary management of the patient with laryngeal and hypopharyngeal is key, as many vital functions are affected by this devastating disease.

Abstract
To compare the impact of transoral radiofrequency microsurgery (TRM) and radiotherapy (RT) on long-term swallowing function in patients with T1 glottic carcinoma. A total of 41 cases of T1 glottic carcinoma treated with TRM or RT alone more than 5 years ago were collected, including 17 cases treated with TRM (TRM group) and 24 cases treated with RT (RT group). The Chinese version of the Swallowing Quality-of-Life Questionnaire (CSWAL-QOL) and videofluoroscopic swallowing study results at the last follow-up (more than 5 years after TRM or RT) were assessed. The TRM group scored significantly better than the RT group on overall CSWAL-QOL, the Frequency score, and 6 out of 10 CSWAL-QOL dimensions. The RT group scored significantly better than the TRM group only on the Communication dimension. The dysphagia score (DS) and penetration-aspiration scale (PAS) score of the TRM group were better than those of the RT group. The overall CSWAL-QOL score, the Frequency score, DS, and PAS scores were not significantly different between patients who received conventional radiotherapy and patients who received intensity-modulated radiation therapy. The RT dose was correlated with the DS. TRM provides better swallowing outcomes as compared to RT in management of early glottic cancer. In addition, there is a correlation between RT dose and dysphagia. Prospective studies should be conducted to further evaluate the impact of TRM and RT on swallowing function.

Abstract
Nonsurgical primary treatment of early and advanced laryngeal squamous cell carcinoma, employing radiotherapy with or without chemotherapy, is considered a standard of care in many centers throughout the world. When patients have persistent or recurrent disease after non-surgical treatment, salvage surgery is frequently the only remaining potentially curative treatment. Depending on the extent of the residual/recurrent disease, different surgical salvage options are at the surgeon's disposal. In selected cases with limited local disease, salvage transoral laser microsurgery, transoral robotic surgery and open partial laryngectomies can be employed to achieve cure while preserving laryngeal function. For more advanced cases total laryngectomy is necessary. Identifying situations with unacceptable results from surgical salvage may guide future therapies.

Abstract
Patient narratives are a very valuable literary and medical resource. They transcribe the experience of illness into the life stories of the subject and the author. A serious case of cancer triggers the very individual experience of vulnerability, suffering, dependence, and even contingency in the no longer 'open' future. Even after overcoming cancer, life is never the same again. Writing about one's own experience of cancer is a hermeneutic feat of strength with ethical and aesthetic implications. In the age of personalized and evidence-based medicine, patient narratives offer a particular and necessary supplement to the objectifying medical perspective, since they constitute expressions of subjective evidence. This article is based on the direct experience of cancer by the co-author of the narrative. The long history of her illness is presented chronologically in her own words and has been translated from Italian to English. This is followed by an essay, published here for the first time, on "the life beyond cancer", on the patient's time without tumors and the consequences of therapies and mutilating operations. Our methodological approach is based on Havi Carel's Phenomenology of Illness. The close reading of this pathography focuses on three aspects: (1) the effect and power of words; (2) the passage from wariness to awareness; and (3) the maintenance of personal quality of life during and after cancer.

Abstract
In the specific field of laryngeal carcinoma (LSCC), evidence about the interaction between angiogenetic pathway and immune microenvironment has not yet been explored. Given the potential relevance of such an interaction for prognostic and therapeutic purposes, the main aim of this exploratory study was to investigate the existence of a correlation between angiogenesis (quantified through CD31 expression), programmed cell death ligand 1 (PD-L1) expression, and immune microenvironment. A secondary aim was to verify whether considering a combination of angiogenesis and immune microenvironment variables might improve prognostic accuracy compared to the traditional clinical-pathological prognostic tools. CD31-assessed micro-vessel density (MVD), PD-L1 in terms of combined positive score (CPS), and tumour infiltrating lymphocytes (TILs) were assessed on 45 consecutive cases of LSCC. Cox proportional hazards model revealed increasing CD31-assessed MVD values, PD-L1 CPS <1, and TILs count rate <30%, as predictive of reduced disease free survival (DFS). Multivariate analysis found that MVD (p<0.0001) and TILs (p=0.0420) retained their significant independent prognostic value. Spearman's correlation model disclosed a significant negative correlation between CD31-assessed MVD values and PD-L1 CPS (p=0.0040). PD-L1 CPS and TILs count rate were positively correlated (p<0.0001). DFS was significantly lower in the CD31-assessed MVD >7, PD-L1 CPS <1, TILs <30% group than in the MVD ≤7, PD-L1 CPS ≥1, TILs ≥30% group (p=0.0001). These data preliminarily support an integrated interpretation of the prognostic role or angiogenesis and immune microenvironment markers in LSCC. This is of potential clinical relevance suggesting a synergistic effect of the combination of anti-angiogenic drugs with programmed death-1/PD-L1 checkpoint inhibitors in advanced LSCC.

Abstract
Background Enhanced glucose uptake and autophagy are means by which cells adapt to stressful microenvironments. In this study, we investigated the roles of glucose transporter-1 (GLUT-1) and autophagy in laryngeal carcinoma stem cells under hypoxic and low-glucose conditions. Materials and Methods CD133-positive Tu212 laryngeal carcinoma stem cells were purified by magnetic-activated cell sorting and subjected to hypoxic and/or low-glucose conditions. Proliferation was evaluated using a cell-counting kit and a clone-formation assay, and migration capability was measured through a Transwell assay. Autophagy was assessed using transmission electron microscopy. Gene silencing was monitored using shRNA technology and autophagy regulation was manipulated using rapamycin, 3-MA, or chloroquine. Gene expression levels were evaluated by quantitative reverse transcription-polymerase chain reaction and protein levels were assessed via Western blotting. Results Compared to CD133-negative cells, CD133-positive cells showed increased proliferation and migration capabilities, and reduced apoptosis, under hypoxic or low-glucose conditions. CD133-positive cells also showed increased expression of GLUT-1 and autophagy activity. Finally, GLUT-1 knockdown or autophagy inhibition reduced the proliferation and migration of CD133-positive laryngeal carcinoma stem cells. Conclusion Enhanced glucose uptake and autophagy maintain the tumor behaviors of CD133-positive laryngeal carcinoma stem cells under hypoxic and low-glucose conditions.

Abstract
The level of the major endocannabinoids anandamide (AEA) and 2-arachidonoylglycerol (2-AG) are altered in several types of carcinomas, and are known to regulate tumor growth. Thusly, this study hypothesized that the HEp-2 human laryngeal squamous cell carcinoma (LSCC) cell line releases AEA and 2-AG, and aimed to determine if their exogenous supplementation has an anti-proliferative effect in vitro. In this in vitro observational study a commercial human LSCC cell line (HEp-2) was used to test for endogenous AEA and 2-AG release via liquid chromatography-tandem mass spectrometry (LC-MS/MS). The anti-proliferative effect of AEA and 2-AG supplementation was evaluated via WST-1 proliferation assay. It was observed that the HEp-2 LSCC cell line released AEA and 2-AG; the median quantity of AEA released was 15.69 ng mL-1 (range: 14.55-15.95 ng mL-1) and the median quantity of 2-AG released was 2.72 ng -1 (range: 2.67-2.74 ng mL-1). Additionally, both AEA and 2-AG exhibited an anti-proliferative effect. The anti-proliferative effect of 2-AG was stronger than that of AEA. These findings suggest that AEA might function via a CB1 receptor-independent pathway and that 2-AG might function via a CB2-dependent pathway. The present findings show that the HEp-2 LSCC cell line releases the major endocannabinoids AEA and 2-AG, and that their supplementation inhibits tumor cell proliferation in vitro. Thus, cannabinoid ligands might represent novel drug candidates for laryngeal cancers, although functional in vivo studies are required in order to validate their potency.

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

Background This study aims to investigate the clinical efficacy of transoral laser microsurgery and open partial laryngectomy (OPL) in treating T1-2 laryngeal cancer. Methods A retrospective analysis was conducted of 182 patients with T1-2 cancer with anterior vocal commissure (AVC) involvement. The local control (LC), disease-free survival (DFS) and overall survival (OS) rates at 5-year follow-up and the influencing factors were analyzed. Results No significant difference was observed in the LC or DFS rates between the two groups at 3- and 5-year follow-up. No significant difference was found between the two groups with T1-stage disease. The 5-year LC rates were significantly different from patients with grade 3 or 4 tumors on indirect laryngoscopy and patients with class III or IV tumors on the modified Mallampati test (MMT) (log-rank test: χ2=8.037, P=0.005). The 3-year LC rate of OPL in the depth of pathological infiltration (3-5 mm) group was found to be significantly higher than that of TLM. Significant differences in pathological infiltration depth (3-5 mm) existed between the two groups (log-rank test: χ2=5.786, P=0.016). Conclusions T1 lesions are generally limited and superficial, and laser surgery can be well-controlled. For patients with difficult airway exposure, surgeons should have extensive surgical experience and skills. It is recommended that a variety of equipment should be ready so that surgeons can convert to open surgery at any time. For patients with a deep infiltration depth, surgeons should examine laryngoscopy imaging results before surgery.

Abstract
Chemotherapies such as 5-fluorouracil (5-FU) and cisplatin (CDDP) have been widely used to treat laryngeal squamous cell carcinoma (LSCC), the second most common head and neck squamous cell carcinoma. However, chemoresistance seriously impairs chemotherapeutic efficacy. Our present study reveals that 5-FU and CDDP treatment increase the expression of histone deacetylase 1 (HDAC1) in LSCC cells. Consistently, increased levels of HDAC1 are observed in chemoresistant cells. Knockdown of HDAC1 significantly restores the sensitivity of LSCC cells, as HDAC1 increases the expression of interleukin-8 (IL-8), which is essential for LSCC chemoresistance. Mechanistically, HDAC1 directly initiates the transcription of IL-8 though binding to its promoter. Simultaneously, si-HDAC1 increases the levels of miR-93, which binds to the 3'UTR of IL-8 mRNA to trigger its degradation. In summary, the HDAC1/IL-8 axis can confer chemotherapeutic resistance to LSCC cells.

Abstract
PURPOSE The aim of this study was to assess the performance of Narrow Band Imaging (NBI) added to White Light (WL) in the delineation of laryngopharyngeal superficial cancer spread during office-based transnasal flexible endoscopy. METHODS This bi-centric prospective study was conducted between October 2014 and December 2017. We included consecutive patients with laryngopharyngeal malignant tumors. Transnasal flexible endoscopy was performed by two endoscopists who were blinded to each other's assessments and who examined each patient independently. The first endoscopist only performed a WL examination, while the second endoscopist carried out both WL and NBI. The extent of tumor involvement was reported based on predefined anatomical sub-units. Biopsies in NBI + /WL- sub-units were subsequently performed during panendoscopy. RESULTS Eighty-four patients were included in the study. A total of 72 NBI + /WL- sub-units were sampled in 38 patients, and 37 of the biopsies were positive (51.4%): 16 for invasive carcinoma, 17 for high-grade dysplasia/carcinoma in situ and 4 for low-grade dysplasia. Ultimately, 26.2% of patients had at least one positive biopsy in an NBI + /WL- sub-unit and, therefore, a better tumor delineation. The clinical T stage was upgraded in 4.8% of cases examined. CONCLUSION Adding NBI to WL imaging during transnasal flexible endoscopy in patients presenting with laryngopharyngeal pre-malignant or malignant lesions improves the delineation of superficial cancer spread, thereby leading to better adapted treatments. Clinicaltrials.gov registration number: NCT02035735.

Abstract
PURPOSE OF REVIEW To give an overview of the current knowledge regarding the diagnosis, treatment, and follow-up of laryngeal dysplasia (LD) and to highlight the contributions of recent literature. The diagnosis of LD largely relies on endoscopic procedures and on histopathology. Diagnostic efficiency of endoscopy may be improved using videolaryngostroboscopy (VLS) and bioendoscopic tools such as Narrow Band Imaging (NBI) or Storz Professional Image Enhancement System (SPIES). Current histological classifications are not powerful enough to clearly predict the risk to carcinoma evolution and technical issues such as sampling error, variation in epithelial thickness and inflammation hamper pathological examination. Almost all dysplasia grading systems are effective in different ways. The 2017 World Health Organization (WHO) system should prove to be an improvement as it is slightly more reproducible and easier for the non-specialist pathologist to apply. To optimize treatment decisions, surgeons should know how their pathologist grades samples and preferably audit their transformation rates locally. Whether carcinoma in situ should be used as part of such classification remains contentious and pathologists should agree with their clinicians whether they find this additional grade useful in treatment decisions. Recently, different studies have defined the possible utility of different biomarkers in risk classification. The main treatment modality for LD is represented by transoral laser microsurgery. Radiotherapy may be indicated in specific circumstances such as multiple recurrence or wide-field lesions. Medical treatment currently does not have a significant role in the management of LD. Follow-up for patients treated with LD is a fundamental part of their care and investigations may be supported by the same techniques used during diagnosis (VLS and NBI/SPIES).

Abstract
Purpose of review To give an overview of the current knowledge regarding the aetiology, epidemiology, and classification of laryngeal dysplasia (LD) and to highlight the contributions of recent literature. As most cases of dysplasia occur at the glottic level and data on diagnosis and management are almost exclusively from this location, laryngeal dysplasia in this position paper is taken to be synonymous with dysplasia of the vocal folds. Summary LD has long been recognized as a precursor lesion to laryngeal squamous cell carcinoma (SCC). Tobacco and alcohol consumption are the two single most important etiological factors for the development of LD. There is currently insufficient evidence to support a role of reflux. Although varying levels of human papillomavirus have been identified in LD, its causal role is still uncertain, and there are data suggesting that it may be limited. Dysplasia has a varying presentation including leukoplakia, erythroleukoplakia, mucosal reddening or thickening with exophytic, “tumor-like” alterations. About 50% of leukoplakic lesions will contain some form of dysplasia. It has become clear that the traditionally accepted molecular pathways to cancer, involving accumulated mutations in a specific order, do not apply to LD. Although the molecular nature of the progression of LD to SCC is still unclear, it can be concluded that the risk of malignant transformation does rise with increasing grade of dysplasia, but not predictably so. Consequently, grading systems are inherently troubled by the weak correlation between the degree of the dysplasia and the risk of malignant transformation. The best data on LD grading and outcomes come from the Ljubljana group, forming the basis for the World Health Organization classification published in 2017.

Abstract
Background Advanced stage operable cancers of larynx are treated with total laryngectomy including thyroid resection in most of the cases, which may expose patient to hypothyroidism and hypoparathyroidism. The requirement of thyroidectomy during Total Laryngectomy is controversial. Methods A cross sectional observational study was set out to review preoperative clinical and radiological assessment; intraoperative and histopathological findings; and follow-up data to predict thyroid gland invasion in the setting of squamous cell carcinoma of the Larynx. Results 11 (16%) out of 69 patients had thyroid gland involvement on histopathological examination with mean age 63 years. Out of these 11 cases, 8 (72%) underwent primary total laryngectomy. 90% patients with thyroid gland involvement were male. 9 cases with thyroid gland involvement were staged as T4a preoperatively. Conclusion Invasion of thyroid gland by laryngeal cancer is uncommon. Unnecessary hemithyroidectomies lead to hypothyroidism and hypoparathyroidism. The study points out the clear indications of thyroid excision in patients undergoing total laryngectomy. We can suggest that total thyroidectomy should be done with total laryngectomy in cases which have gross clinical, radiological or intraoperative thyroid gland involvement, subglottic extension and thyroid cartilage invasion. This can save the patients from the brunt of unnecessary morbid hypothyroidism and hypoparathyroidism.

Abstract
OBJECTIVE To assess correlations between auditory-perceptual and self-reported speech evaluation methods for substitution voicing (SV) and to investigate the robustness of these methods in a clinical setting. METHODS Fifty-nine male patients who underwent laryngeal oncosurgery and 62 healthy male controls were included in this prospective study. Lithuanian versions of the Speech Handicap Index (SHI-LT) and Impression of voice quality (I), Impression of intelligibility (I), Unintended additive Noise (N), Fluency (F), and Quality of Voicing (Vo) scale (IINFVo-LT) were used to assess and compare self-reported and auditory-perceptual evaluations of SV. Speech samples were rated by a panel of experienced raters. RESULTS The IINFVo-LT revealed good inter-rater reliability (ICC = 0.825) and intrarater reliability over time (ICC = 0.976) when assessing SV. Statistically significant differences (P < 0.05) of the mean scores of IINFVo-LT among the cordectomy, partial laryngectomy (22.52 [SD 9.98]), tracheoesophageal prosthesis (16.92 [SD 10.71]), and control (48.01 [SD 2.88]) groups confirmed the usefulness of IINFVo-LT for SV rating. A moderate negative correlation (r = -0.61; P < 0.001) demonstrated good concurrent validity between the IINFVo-LT and the SHI-LT total scores. A statistically significant, strong, negative correlation (r = -0.74) was obtained between the IINFVo-LT and SHI-LT speech handicap grade (P < 0.001), demonstrating good concurrent validity. CONCLUSION The combination of IINFVo-LT and SHI-LT represents a potentially valuable and robust tool for evaluating SV and is helpful for assessing the degree of speech abnormality after laryngeal oncosurgery and its impact on patients' quality of life.

Abstract
BACKGROUND The purpose of this study was to investigate the pathohistological status of mucous lining infected with Helicobacte pylori as the possible cause of chronic laryngitis and laryngeal carcinoma. MATERIALS AND METHODS The prospective examination included 51 patients suffering from planocellular laryngeal cancer and 26 examinees suffering from chronic laryngitis. The examinees and the control group were subjected to esophagogastroduodenoscopy which described the local status of the esophagus and stomach. Two biopsy samplings are taken from the stomach antrum and corpus. One part of the biopsies was colored using the histological technique used in the pathohistological detection of H. pylori, while the other part was incorporated in paraffin cubes where the H. Pylori gene expression was determined using the deparaffinization and PCR method DNA isolation. RESULTS In the group of examinees suffering from laryngeal tumor, there were a higher number of patients suffering also from chronic gastritis (32/51) than in the other group, suffering from chronic laryngitis (9/26). In the chronic laryngitis group, there were more examinees with acute gastritis (12/26) than in the examined group (11/51). The difference is statistically significant (p = 0.0457). CONCLUSION Chronic gastritis and H. pylori infection are risk factors for laryngeal carcinoma formation; therefore, acute gastritis with helicobacter pylori infection must be immediately treated to not let infection to become chronic.

Abstract
Background: Neoadjuvant chemotherapy is important for advanced laryngeal and hypopharyngeal carcinoma (LHC).Aims/objectives: To determine the efficacy and toxicity of the combination of docetaxel, nedaplatin, and 5-fluorouracil in induction treatment of advanced LHC.Material and methods: A total of 157 cancer patients were included. The primary endpoints of this study were overall response rate, pathological complete response rate, the safety of induction treatment, progression-free survival (PFS), and overall survival (OS).Results: After two-cycle induction treatment, 17(10.8%) patients experienced complete remission, 76 (48.4%) experienced partial remission, 47 (30.0%) had stable disease, and 17 (10.8%) had progressive disease. The TNM stage decreased by two or more in 17 cases, decreased by one in 71 cases, increased in 15 cases, and did not change in 54 cases after induction treatment. Most of the adverse chemotherapy responses were alleviated by symptomatic management. After the induction treatment, 29 patients continued receiving chemotherapy followed by radiotherapy, and 112 underwent surgical management depending on tumor site followed by radiotherapy. The median PFS was 13.00 ± 2.10 months and the median OS was 14.20 ± 0.29 months.Conclusions and significance: Combination of docetaxel, nedaplatin, and 5-fluorouracil plays an important role in the comprehensive treatment of advanced LHC.

Abstract
BACKGROUND The role of primary tumor resection in patients with distant metastatic laryngeal carcinoma (DMLC) has not been clarified completely. Thus, we used propensity score matching (PSM) and survival analysis to address this issue. METHODS The PSM was utilized to avoid selection bias and disproportionate distributions of the confounding factors. Kaplan-Meier estimates and Cox proportional hazard analysis were utilized to evaluate overall survival (OS) and cancer-specific survival (CSS). RESULTS From the Surveillance, Epidemiology, and End Results Program database, a cohort of 480 patients with DMLC were included. After PSM, the OS and CSS for patients who underwent resection were significantly longer than those without resection (median OS: 19 months vs. 8 months, P < 0.001; median CSS: 19 months vs. 9 months, P = 0.002). Tumor resection significantly prolonged survival of DMLC patients with appropriate demographic and clinical characteristics. In the multivariate analysis, age at diagnosis, race, pathologic subtype, and marital status were found significantly affecting both OS and CSS of patients who underwent surgical resection. Predictive nomograms were developed to help distinguish patients with early mortality potential after surgical resection. CONCLUSIONS This study is the first one using PSM to assess the role played by surgical resection in DMLC and evaluate the prognostic factor of resected patients. Premised on well controlled postoperative complications, resection could significantly prolong OS and CSS of certain patients.

Abstract
A 75-year-old male patient was hospitalized in hoarseness for 2 months. Laryngoscopy showed a mass protruding in right laryngeal chamber and covering the middle part of right vocal cord. Since tumor biopsy showed low differentiation cancer, he received total laryngectomy, and post-operative pathological result found composite carcinoma, which containing medium differentiated squamous cell carcinoma (about 5%) and low differentiated neuroendocrine carcinoma (about 95%). The growth status of tumor indicated it was collision carcinoma. After postoperative regular radiotherapy, no recurrence was found at 6 months of follow-up. The incidence of head and neck collision carcinoma is quite low, and the majority of them occurs in thyroid, which is rare in larynx. The confirmed diagnosis of larynx collision carcinoma is based on postoperative pathological study. The choice of treatment for collision cancer is closely related to the pathological components, the location of the disease and whether there is distant metastasis.

Abstract
Objective The aim of this study is to compare pre-therapeutic staging of the loco-regional lymphatic basin and subsequent surgical management in cN0 versus cN+ hypopharyngeal and laryngeal cancer patients. Methods We analyzed all hypopharyngeal and laryngeal carcinoma patients treated surgically at a single quaternary medical care and cancer center between 2004 and 2014. We established two groups for patients who underwent neck dissection comparing patients with a low LNR (lymph node ratio) to one with a high LNR. Regarding the cN0 cohort, elective neck dissection was evaluated as a secondary predictor variable. Comorbidities, such as anemia and renal insufficiency, were analyzed as potentially influencing disease-free (DFS) and overall survival (OS). Results A total of 310 patients (185 glottic and 125 supraglottic/hypopharyngeal carcinoma) were included. Pre-therapeutic neck MRI-/CT-scan and concomitant neck ultrasound revealed cN+ status in 144 patients resulting in a significant over-staging in 63 patients (44%) who were rated as being pN0 after histological examination. 166 patients were staged cN0 and 21 underwent elective neck dissection (11 local advanced glottic and 10 supraglottic/hypopharyngeal carcinoma). Two cN0 patients showed occult cervical lymph node metastases (10%). Furthermore, we could detect a significant negative impact of the LNR divided by the number of dissected lymph nodes and OS. Conclusion The pre-therapeutic clinical evaluation of lymphatic outgrowth is over-staged. OS decreases with increasing LNR divided by the number of dissected lymph nodes. Renal insufficiency and anemia are significant negative factors, decreasing both OS and DFS.

Abstract
Increasing evidence indicates that long non-coding RNA (lncRNA) may play important roles in tumorigenesis. Increased lncRNA CASC9 occurs in laryngeal carcinoma, which accounts for 20% of all head and neck cancers, but its role in this disease remains unknown. Using quantitative reverse transcriptase PCR, we found higher expression of CASC9 and GLUT-1 in laryngeal carcinoma tissues and cells, compared to adjacent tissues and cells. A correlation analysis showed a positive relationship between CASC9 and GLUT-1 expression in laryngeal carcinoma tissues. An MTT assay of TU212 and Hep-2 cells showed increased cell proliferation after transfection with overexpressed CASC9 and decreased cell proliferation after transfection with silenced CASC9. A Transwell assay showed that overexpressing CASC9 increased and silencing CASC9 decreased cell migration of TU212 and Hep-2 cells. A flow cytometry assay showed that overexpressing CASC9 reduced and silencing CASC9 increased cell apoptosis. In other words, we found that overexpressing CASC9 increased cell proliferation and cell migration and decreased apoptosis both in TU212 and Hep-2 cells, whereas silencing CASC9 had the opposite effects. Moreover, overexpression vector of GLUT-1 was used to investigate the molecular mechanism of CASC9 in laryngeal carcinoma. The results showed that transfection with an overexpressed GLUT-1vector reversed the effects of silencing CASC9 on proliferation, migration, and apoptosis in TU212 and Hep-2 cells. In conclusion, our study of laryngeal carcinoma found that CASC9 was positively correlated with GLUT-1 expression and that CASC9 may promote proliferation and metastasis of laryngeal carcinoma cells by regulating GLUT-1.
