Abstract
This study investigates the role of M2-exo-mediated HOXC13-AS in laryngeal squamous cell carcinoma (LSCC) by examining its transmission to tumor microenvironment (TME) macrophages. Exosomes from M2 macrophages were isolated and characterized using transmission electron microscopy, nanoparticle tracer analysis and western blot. Expression of HOXC13-AS, miR-485-5p, IGF2BP2, and PD-L1 was analyzed. Different interventions on LSCC cell function and immune escape were detected using molecular biological techniques. The study found that elevated HOXC13-AS were present in LSCC, and M2-exo expression was significantly increased in LSCC cells. Silencing HOXC13-AS in M2-exo inhibited LSCC malignant progression and immune escape in vivo and in vitro. M2-exo-mediated HOXC13-AS also regulated IGF2BP2 expression, impacting cellular biological function and immune escape process. The study concludes that M2-exo-mediated HOXC13-AS promotes LSCC malignancy and immune escape.

Abstract
BACKGROUND Laryngeal cancer (LC) is among of the most frequent head and neck cancers, associated to a high social impact and mortality. Unfortunately, the current treatment outcomes of LC are often scant, with different factors affecting patient's prognosis (i.e., advanced age, advanced disease stage, lymph node involvement, tumor pathological features, type of intervention). The aims of the present study were: 1) to evaluate the epidemiological and clinical features of patients affected by LC; and 2) to focus on tumor risk factors affecting patient's overall survival (OS) and recurrences. METHODS A retrospective analysis of all patients affected by LC and surgically treated at two different hospital settings has been performed. RESULTS Two hundred twenty-five patients were enrolled in the present study; of these 189 were males (84%) and 36 (16%) were females. The most frequently performed surgery was total laryngectomy. Thirty-two (14.2%) patients experienced local recurrence, while 15 patients (6.6%) had regional recurrence and 15 distant metastases. Multivariate analysis showed that locoregional recurrence was associated to the occurrence of distant metastases (P=0.002, HR=25,35). Analyzing OS, the only statistically significant factor that correlated with an increased risk of mortality (P<0.015, HR=2,45) was locoregional recurrence. CONCLUSIONS The present study confirms the literature data about age and sex distribution of LC, about tumors localization, lymph nodes metastasis and distant metastasis incidence and OS rate, based on T and N stage. Interestingly, within this series, the presence of locoregional recurrence or distant metastasis is related to a worst prognosis and a lower overall survival rate.

Abstract
Objective: To assess the prognostic utilities of various risk factors for laryngeal squamous cell carcinoma. Methods: Six databases were searched to January 2022. Hazard ratios for overall survival and disease-free survival were collected and study characteristics were recorded. The risk of bias was evaluated using the Newcastle–Ottawa scale. Results: Twenty-eight studies involving 32,128 patients were finally included. In terms of overall survival, older age, a history of alcohol consumption, a high Charlson comorbidity index score, a high TNM stage (III and IV), a high tumor stage (III and IV), nodal involvement, poor pathological differentiation, primary chemoradiotherapy and radiotherapy were associated with increased risks of death. In terms of disease-free survival, older age (≥60 years), TNM stages III and IV, tumor stages III and IV, supraglottic tumors, and nodal involvement all increased the risk of death. Conclusions: The TNM stage importantly predicts overall survival, and tumor location predicts the disease-free survival of patients with laryngeal squamous cell carcinoma. Of patients with risk factors, the Charlson comorbidity index usefully predicts overall survival.

Abstract
OBJECTIVE Chemoradiation for patients with laryngeal squamous cell carcinoma (SCC) may achieve organ preservation, but appropriate patient selection remains unknown. This study investigates pre-treatment risk factors associated with functional and survival outcomes after radiation-based therapy in patients with advanced laryngeal SCC. METHODS A retrospective cohort study was performed on 75 adult patients with stage III or IV laryngeal SCC receiving definitive radiation-based therapy from 1997 to 2016 at a tertiary care center. Tracheostomy and gastrostomy dependence were the primary functional outcomes. Multivariable logistic regressions were performed to evaluate relationships between pre-treatment factors and tracheostomy and gastrostomy dependence. Time-to-event analyses were performed to determine risk factors associated with overall survival. RESULTS Among 75 patients included in the analysis, 30 (40%) patients were tracheostomy dependent and 31 (41%) were gastrostomy tube dependent. The median length of follow-up was 31 months (range = 1 to 142 months). Pre-treatment tracheostomy was a significant predictor of post-treatment tracheostomy (aOR = 13.9, 95% CI = 3.35 to 57.5) and moderate-severe comorbidity was a significant predictor of post-treatment gastrostomy dependence (aOR = 2.96, 95% CI = 1.04 to 8.43). The five-year overall survival was 51% (95% CI = 38 to 64%). Pre-treatment gastrostomy tube dependence was associated with an increased risk of death (aHR = 2.45, 95% CI = 1.09 to 5.53). CONCLUSIONS Baseline laryngeal functional status and overall health in advanced laryngeal SCC are associated with poor functional outcomes after radiation-based therapy, highlighting the importance of patient selection when deciding between surgical and non-surgical treatment plans.

Abstract
PURPOSE Results of laryngeal squamous cell carcinoma (LSCC) treatment and the 5 year survival rate of these patients remain poor. To purify therapeutic targets, investigation of new specific and prognostic blood-based markers for LSCC development is essential. METHODS In the present study, we evaluated five single nucleotide polymorphisms (SNPs): IL1RAP rs4624606, IL1RL1 rs1041973, IL-6 rs1800795, BLK rs13277113, and TIMP3 rs9621532, and determined their associations with the patients' 5 year survival rate. Also, we performed a detailed statistical analysis of different LSCC patients' characteristics impact on their survival rate. RESULTS Three hundred fifty-three LSCC patients and 538 control subjects were included in this study. The multivariable Cox regression analysis revealed a significant association between patients' survival rate and distribution of IL1RAP rs4624606 variants: patients carrying AT genotype at IL1RAP rs4624606 had a lower risk of death (p = 0.044). Also, it was revealed that tumor size (T) (p = 0.000), tumor differentiation grade (G) (p = 0.015), and IL1RAP rs4624606 genotype (p = 0.044) were effective variables in multivariable Cox regression analysis prognosing survival of LSCC patients. The specific-LSCC 5 year survival rate was 77%. CONCLUSIONS In summary, our findings indicate that the genotypic distribution of IL1RAP rs4624606 influences the 5 year survival rate of LSCC patients. The results of the present study facilitate a more complete understanding of LSCC at the biological level, thus providing the base for the identification of new specific and prognostic blood-based markers for LSCC development.

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
Background. The possible role and detailed mechanisms of Tumor-associated macrophages (TAMs) in laryngeal squamous cell carcinoma (LSCC) have not been revealed. Methods. The expressions of typical markers were evaluated by qRT-PCR. In macrophages cocultured with TU212 cells, CD163, and CD206 protein expressions were detected by western blot analysis; IL-10 and IL-12 expressions were detected by ELISA assay. Exosomes isolated from TU212 cells were characterized by TEM analysis. As for the TU212 cells cocultured with macrophages processed with HOK or TU212 cells derived exosomes, their viability, migration, and invasion were assessed by CCK-8 assay, wounding healing, and Transwell assays, respectively. Results. In this study, macrophages processed with exosomes from human TU212 cells notably advanced LSCC cell viability, migration, and invasion. miR-1246 inhibitor suppressed the M2 polarization of macrophages. Macrophages transfected with miR-1246 inhibitor suppressed LSCC cell viability, migration, and invasion. Conclusion. In summary, our data implied that the exosomal, miR-1246 of LSCC, induced polarization of M2 type macrophages and promoted the progression of LSCC. This trial is registered with 2020-13.

Funct Integr Genomics 2022; 22:1-13.

Abstract
New evidence suggests that abnormal expression of circular RNA (circRNA) is associated with the development of human cancers. This study aims to reveal circMYOF roles in the malignant phenotype of laryngeal squamous cell carcinoma (LSCC). The expression of circMYOF, microRNA (miR)-145-5p, and orthodenticle homeobox 1 (OTX1) was detected by quantitative real-time PCR. Cell proliferation, migration, invasion, and apoptosis were determined using colony formation assay and EdU assay, wound healing assay, transwell assay, and flow cytometry, respectively. Protein expression was examined by western blot analysis. Cell glycolysis was assessed by detecting glucose consumption and lactate production. Mice xenograft models were constructed to evaluate the regulation of circMYOF on LSCC tumorigenesis. The regulatory relationships among circMYOF, miR-145-5p, and OTX1 were identified using dual-luciferase reporter assay and RIP assay. Serum exosomes were isolated to confirm the existence of circMYOF in LSCC patients. CircMYOF was upregulated in LSCC tissues and cells, and its knockdown suppressed LSCC cell growth, metastasis, and glycolysis, as well as inhibited LSCC tumor growth. MiR-145-5p had decreased expression in LSCC, and it could be sponged by circMYOF. The inhibition effect of circMYOF lentivirus short hairpin RNA (sh-circMYOF) on LSCC progression was restored by the inhibitor of miR-145-5p (in-miR-145-5p). Also, OTX1 was targeted by miR-145-5p and was positively regulated by circMYOF. MiR-145-5p could repress LSCC progression, and OTX1 overexpression also eliminated this effect. In addition, we found that circMYOF was significantly overexpressed in the serum exosomes of LSCC patients. Our data revealed that circMYOF contributed to LSCC progression by promoting cell growth, metastasis, and glycolysis through miR-145-5p/OTX1 axis.

Abstract
Objective To explore whether dihydroartemisinin (DHA) can block interleukin (IL)-6-induced epithelial–mesenchymal transition (EMT) in laryngeal squamous cell carcinoma (LSCC). Methods The expression of SLUG, signal transducer and activator of transcription 3 (STAT3), and microRNA (miR)-130b-3p was measured. In addition, a dual-luciferase reporter assay was performed to examine the interaction of miR-130b-3p with STAT3. Results We found that IL-6 can promote EMT and invasion in LSCC cells, whereas DHA can inhibit these two processes. However, DHA alone does not influence EMT and cancer invasion. Furthermore, DHA upregulated miR-130b-3p, which can downregulate STAT3 and β-catenin protein expression and decrease the activity of the IL-6/STAT3 signaling pathway. Moreover, we found that miR-130b-3p can target STAT3 directly. Conclusions DHA can block IL-6-triggered EMT and invasion in LSCC, and during these processes, DHA increases miR-130b-3p expression to decrease the activation of the IL-6/STAT3 and β-catenin signaling pathways. These findings may provide new insights into strategies for suppressing and even preventing LSCC metastasis.

Abstract
Laryngeal carcinoma is a malignant disease with high morbidity and mortality. Several studies have indicated that miRNA dysfunction involves in the development of laryngeal carcinoma. In this study, the connection of miR-339-5p and laryngeal carcinoma was investigated, and qRT-PCR, CCK-8, and flow cytometry assay were used to observe the function of miR-339-5p on laryngeal carcinoma. Besides, the target database, dual-luciferase reporter assay, and western blot were used to explore the regulation mechanism of miR-339-5p on the progression of laryngeal carcinoma. The results showed that miR-339-5p was significantly downregulated in cisplatin-resistant cells of laryngeal carcinoma, and miR-339-5p upregulation could weaken the resistance of laryngeal carcinoma cells on cisplatin. Moreover, miR-339-5p could directly react with 3'-UTR of TAK1, and TAK1 could reverse the effects of miR-339-5p on the progression of autophagy. In conclusion, this study suggests that miR-339-5p can inhibit the autophagy to decrease the cisplatin resistance of laryngeal carcinoma via targeting TAK1.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is a frequent cancer subtype among head and neck cancers. Exacerbated inflammation and nutritional deficit are common features in this type of cancer and can be used as a prognostic marker. This study aimed to investigate the relationship between body mass index (BMI), neutrophil-to-lymphocyte ratio (NLR), and systemic inflammation response index (SIRI) on overall survival (OS) of LSCC patients. In this retrospective cohort study, 168 patients were followed for 5 years. Data on clinical factors, patients' life habits, height, weight, and hematological parameters were collected. BMI, NLR, and SIRI were calculated. Pretreatment NLR≥ 2.02 and SIRI≥ 1160.85 were independent prognostic factors for poor OS. Low BMI did not significantly affect the OS. However, the inflammatory parameters had their predictive capacity altered when stratified by the BMI classification. NLR≥ 2.02 + Low BMI or SIRI≥ 1160.85 + Low BMI increased in 8.6 and 3.8 times the risk of death, respectively. In contrast, stratification by normal/high BMI classification eliminated the predictive capacity of NLR and SIRI. Here, we demonstrated the possible ability of BMI to change the prognostic capacity of inflammatory markers NLR and SIRI in patients with LSCC.Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2021.1952447.

Abstract
Interleukin 24 (IL24) has been documented to be highly expressed in several cancers, but its role in laryngeal squamous cell carcinoma (LSCC) remains unclarified. In this study, to reveal the function and its clinical significance of IL24 in LSCC, multiple detecting methods were used comprehensively. IL24 protein expression was remarkably higher in LSCC (n= 49) than non-cancerous laryngeal controls (n= 26) as detected by in-house immunohistochemistry. Meanwhile, the IL24 mRNA expression was also evaluated based on high throughput data from Gene Expression Omnibus, The Cancer Genome Atlas, ArrayExpress and Oncomine databases. Consistently with the protein level, IL24 mRNA expression level was also predominantly upregulated in LSCC (n= 172) compared to non-cancerous laryngeal tissues (n= 81) with the standard mean difference (SMD) being 1.25 and the area under the curve (AUC) of the summary receiver operating characteristic (sROC) being 0.89 (95% CI = 0.86-0.92). Furthermore, the related genes of IL24 and the differentially expressed genes (DEGs) of LSCC were intersected and sent for Gene ontology (GO) enrichment, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, and the protein-protein interaction (PPI) analyses. In the GO annotation, the top terms of biological process (BP), cellular component (CC) and molecular function (MF) were extracellular matrix organization, extracellular matrix, cytokine activity, respectively. The top pathway of KEGG was ECM-receptor interaction. The PPI networks indicated the top hub genes of IL24-related genes in LSCC were SERPINE1, TGFB1, MMP1, MMP3, CSF2, and ITGA5. In conclusion, upregulating expression of IL24 may enhance the occurrence of LSCC, which owns prospect diagnostic ability and therapeutic significance in LSCC.

Abstract
Background The survival rate of patients with laryngeal squamous cell carcinoma (LSCC) is correlated with several factors. However, the independent prognostic factors of patients with LSCC remain unclear. Thus, we sought to identify prognostic factors affecting LSCC outcomes in the Chinese population. Methods The survival and potential prognostic factors of 211 patients with LSCC between April 2011 and July 2019 were retrospectively analyzed. Overall survival (OS) and progression free survival (PFS) were estimated by the Kaplan Meier method, and a log-rank test was used to compare the possible prognostic factors between different groups. The Cox proportional hazard model was used to perform multivariable analysis of significant covariants. Results A total of 211 LSCC patients were included, of which 164 (77.7%) were male and 47 (22.3%) were female. Mean age was 62.19 ± 8.328 years. A univariate analysis showed that seven factors including pathological differentiation, clinical stage, tobacco consumption, alcohol consumption, T stage, N stage, and concurrent chemoradiotherapy were correlated with survival (P<0.05). Cox proportional hazards regression analyses revealed that clinic stage (hazard ratio=3.100, p=0.048), pathological differentiation (hazard ratio = 2.538, p=0.015), alcohol consumption (hazard ratio = 8.456, p =0.004) were associated with OS in LSCC. Pathological differentiation (hazard ratio =5.677, p=0.000), alcohol consumption (hazard ratio =6.766, p=0.000) were associated with PFS in LSCC. Conclusions Pathological differentiation, alcohol consumption, are independent prognostic factors and predictors of recurrence in LSCC. These factors could help inform guidelines for clinical treatment and prognosis.

Abstract
Laryngeal squamous cell carcinoma (LSCC) and hypopharyngeal squamous cell carcinoma (HPSCC) are two types of head and neck cancers with high incidence rates and relatively poor prognoses. The aim of the present study was to determine the effects of microRNA (miR/miRNA)-136-5p and its downstream target, Rho-associated coiled-coil containing protein kinase 1 (ROCK1), on LSCC and HPSCC progression and cisplatin sensitivity. The miRNA and protein expression levels in head and neck cancer cell lines were evaluated using reverse transcription-quantitative PCR and western blotting, respectively. MTT, wound healing assays, transwell assays and flow cytometry analysis were performed to measure cell properties. The binding between miR-136-5p and ROCK1 was detected using a dual-luciferase reporter assay. Autophagy double-labeled adenoviral infection assays were used to assess cell autophagy. The results showed that miR-136-5p was expressed in LSCC and HPSCC cells. Functional experiments showed that the expression of miR-136-5p in LSCC and HPSCC cells was negatively correlated with cell viability, invasion and migration. Additionally, miR-136-5p overexpression inhibited epithelial-mesenchymal transition, whereas miR-136-5p knockdown had the opposite effect. Dual-luciferase reporter assays confirmed the targeting relationship between miR-136-5p and ROCK1. miR-136-5p overexpression increased the cisplatin sensitivity of LSCC and HPSCC cells by reducing cell viability, as well as promoting cell apoptosis and autophagy. miR-136-5p overexpression decreased the expression levels of its downstream target ROCK1 and attenuated activity of the Akt/mTOR signaling pathway in cisplatin-treated LSCC and HPSCC cells. Conversely, miR-136-5p knockdown increased ROCK1 levels and decreased cisplatin sensitivity of the LSCC and HPSCC cells by increasing cell viability and inhibiting cell apoptosis, which was reversed by ROCK1 inhibition using the ROCK1 inhibitor, Y27632. Taken together, the results showed that the miR-136-5p/ROCK1 axis inhibits cell invasion and migration, and increases the sensitivity of LSCC and HPSCC cells to cisplatin.
