Treatment Patterns and Outcomes in Pancreatic Cancer: A Comparative Analysis of Ontario and the USA. Ann Surg Oncol 2024; 31:58-65. [PMID: 37833463 DOI: 10.1245/s10434-023-14375-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 09/15/2023] [Indexed: 10/15/2023]
Abstract
BACKGROUND Comparative studies evaluating quality of care in different healthcare systems can guide reform initiatives. This study seeks to characterize best practices by comparing utilization and outcomes for patients with pancreatic cancer (PC) in the USA and Ontario, Canada. METHODS Patients (age ≥ 66 years) with PC were identified from the Ontario Cancer Registry and SEER-Medicare databases from 2006 to 2015. Demographics and treatment (surgery, radiation, chemotherapy, or multimodality (surgery and chemotherapy)) were described. In resected patients, neoadjuvant therapy, readmission, and 30- and 90-day postoperative mortality rates were calculated. Survival was assessed using Kaplan-Meier curves. RESULTS This study includes 38,858 and 11,512 patients with PC from the USA and Ontario, respectively. More female patients were identified in the USA (54.0%) versus Ontario (46.9%). In the entire cohort, US patients received more radiation in addition to other therapies (18.8% vs. 13.5% Ontario) and chemotherapy alone (34.3% vs. 19.0% Ontario). While rates of resection were similar (13.4% USA vs.12.5% Ontario), multimodality therapy was more common in the UAS (9.0% vs. 6.4%). Among resected patients, neoadjuvant chemotherapy was uncommon in both groups, although more frequent in the USA (12.0% vs. 3.2% Ontario). The 30- and 90-day postoperative mortality rates were lower in Ontario vs. the USA (30-day: 3.26% vs. 4.91%; 90-day: 7.08% vs. 10.96%), however, overall survival was similar between the USA and Ontario. CONCLUSIONS We observed substantive differences in treatment and outcomes between PC patients in the USA and Ontario, which may reflect known differences in healthcare systems. Close evaluation of healthcare policies can inform initiatives to improve care quality.

Zhong R, Zhan J, Zhang S. Integrative Analysis Reveals STC2 as a Prognostic Biomarker of Laryngeal Squamous Cell Carcinoma. Appl Biochem Biotechnol 2023:10.1007/s12010-023-04727-z.

Abstract
Stanniocalcin 2 (STC2) is involved in many tumour types, but it remains unclear what its biological function is in laryngeal squamous cell carcinoma (LSCC). Therefore, we investigated STC2's expression, potential function, and prognostic significance of in LSCC. The expression and prognosis of STC2 in LSCC were described using the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases. In the TCGA database, the relationship between STC2 and immune infiltration, expression of immune cell chemokine and receptor genes, immune cell molecular marker genes, and epithelial‒mesenchymal transition (EMT) marker genes were analysed. The biological processes involved in STC2 and its expression-related genes were analysed comprehensively using bioinformatics. The single-gene ceRNA network of STC2 was constructed in the TCGA database. Finally, LSCC patients' tumour tissue STC2 expression was verified. STC2 silencing with the RNAi technique was used for the determination of cellular functions in a laryngeal cancer cell line. STC2 expression was higher in most tumours, including LSCC, than in normal tissues and was associated with poor prognosis. The relative proportions of naïve B, plasma, follicular helper T, and macrophage M0 cells in LSCC and normal samples differed significantly. STC2 expression correlated significantly positively with that of TGFB1 (biomarker of Tregs) and significantly negatively with that of D79A and CD19 (biomarkers of B cells). Furthermore, STC2 affected chemokine and receptor gene expression in immune cells. STC2 expression correlated with EMT marker gene expression in LSCC. STC2 was enriched in the PI3K/AKT signalling pathway, extracellular matrix (ECM) organisation, ECM-receptor interaction, and other tumour-related signalling pathways. STC2 was highly expressed in our clinical samples. N-cadherin and vimentin expression were decreased in the TU686 cell line after successful silencing of STC2, indicating that high STC2 expression may prompt LSCC cells to adopt a mesenchymal cell phenotype. STC2 silencing substantially reduced proliferation and migration in the TU686 cell line. STC2 may be a promising predictive biomarker for tumours, providing new approaches for LSCC diagnosis and treatment monitoring.

Abstract
BACKGROUND Lifetime elongation of the silicone voice rubber prostheses by inhibition of biofilm formation is a primary objective in voice restoration of laryngectomized patients. This systematic review sought to explore the existing strategies in this direction. MATERIALS We conducted a systematic search of both in vitro and in vivo literature published in PubMed, Scopus, and Cochrane Central Register of Controlled Trials, until December 31, 2022, for published and unpublished trials assessing the strategies for inhibiting biofilm formation on silicone rubber voice prostheses, and appraised quality assessment with the modified Consolidated Standards of Reporting Trials tool. We analyzed the infection prevention capacity of the included antibacterial and antifungal agents. RESULTS The qualitative synthesis showed that both surface modification methods and prophylactic treatment of silicone rubber voice prostheses present adequate antibiofilm activity. Of note, the majority of the suggested prosthetic surfaces were not chronically exposed to both human fluids and biofilm-forming microorganisms. CONCLUSION Various experimental methods provide promising antibiofilm activity and, thus, possible lifespan elongation of silicone rubber voice prostheses.

Abstract
BACKGROUND Laryngeal cancer is a very common malignant tumor of the head and neck. While laryngeal cancer does not show any obvious early symptoms, it tends to have a poor prognosis in advanced clinical stages. Chromosome region maintenance 1 (CRM1) mediates the nuclear export of some RNAs, major and tumor suppressor proteins and has been associated with the pathogenesis of many tumors. However, the clinicopathological significance of CRM1 gene expression in laryngeal cancer has not been clarified yet. Therefore, this study aims to detect the expression of CRM1 in laryngeal cancer and to investigate its relationship with clinicopathological parameters and prognosis. METHODS CRM1 expression in matched tumor and normal tissues obtained from 43 laryngeal cancer patients were evaluated intracellular for protein and mRNA levels by immunohistochemical staining (IHC), western-blot, and quantitative real-time RT-PCR (qRT-PCR), respectively. RESULTS IHC, western-blot, and qRT-PCR analyses showed that CRM1 expression was significantly increased in laryngeal cancer tissue compared to normal tissue. Increased expression of CRM1 has been associated with poor prognostic clinicopathological features, including advanced tumor stage, increased tumor invasion, larger tumor size, positive lymph node metastasis, distant metastasis, and invasive histological type by IHC, western-blot, and qRT-PCR. Kaplan-Meier survival analysis showed that patients with high expression of CRM1 exhibited lower overall survival compared to those with low expression (Log-rank = 7.16, p = 0.007). According to the The Cancer Genome Atlas (TCGA) datasets, elevated CRM1 expression in head and neck cancer including cases of squamous cell laryngeal origin is associated with advanced tumor stage and histological grade (p > 0.05, for all). DISCUSSION Consequently, CRM1 plays an important role in laryngeal cancer and may serve as an indicator and prognostic factor for poor overall survival in laryngeal cancer patients.

Cancers (Basel) 2023; 15:3644.

Abstract
The problem of cleaning impaired speech is crucial for various applications such as speech recognition, telecommunication, and assistive technologies. In this paper, we propose a novel approach that combines Pareto-optimized deep learning with non-negative matrix factorization (NMF) to effectively reduce noise in impaired speech signals while preserving the quality of the desired speech. Our method begins by calculating the spectrogram of a noisy voice clip and extracting frequency statistics. A threshold is then determined based on the desired noise sensitivity, and a noise-to-signal mask is computed. This mask is smoothed to avoid abrupt transitions in noise levels, and the modified spectrogram is obtained by applying the smoothed mask to the signal spectrogram. We then employ a Pareto-optimized NMF to decompose the modified spectrogram into basis functions and corresponding weights, which are used to reconstruct the clean speech spectrogram. The final noise-reduced waveform is obtained by inverting the clean speech spectrogram. Our proposed method achieves a balance between various objectives, such as noise suppression, speech quality preservation, and computational efficiency, by leveraging Pareto optimization in the deep learning model. The experimental results demonstrate the effectiveness of our approach in cleaning alaryngeal speech signals, making it a promising solution for various real-world applications.

Abstract
BACKGROUND Recent studies have uncovered that the microbiota in patients with head and neck cancers is significantly altered and may drive cancer development. However, there is limited data to explore the unique microbiota of laryngeal squamous cell carcinoma (LSCC), and little is known regarding whether the oral microbiota can be utilized as an early diagnostic biomarker. METHODS Using 16S rRNA gene sequencing, we characterized the microbiome of oral rinse and tissue samples from 77 patients with LSCC and 76 control patients with vocal polyps, and then performed bioinformatic analyses to identify taxonomic groups associated with clinicopathologic features. RESULTS Multiple bacterial genera exhibited significant differences in relative abundance when stratifying by histologic and tissue type. By exploiting the distinct microbial abundance and identifying the tumor-associated microbiota taxa between patients of LSCC and vocal polyps, we developed a predictive classifier by using rinse microbiota as key features for the diagnosis of LSCC with 85.7% accuracy. CONCLUSION This is the first evidence of taxonomical features based on the oral rinse microbiome that could diagnose LSCC. Our results revealed the oral rinse microbiome is an understudied source of clinical variation and represents a potential non-evasive biomarker of LSCC.

Abstract
Early failure of silicone voice prostheses resulting from fungal colonization and biofilm formation poses a major concern in modern ear nose throat surgery. Therefore, developing new infection prevention techniques to prolong those implants' survivorship is crucial. We designed an in vitro laboratory study to include nanomaterial-enhanced polymer coating with a plasma spraying technique against Candida albicans growth to address this issue. The anti-biofilm effects of high- and low-dose Al2O3 nanowire and TiO2 nanoparticle coatings were studied either alone or in conjunction with each other using checkerboard testing. It was demonstrated that both nanomaterials were capable of preventing fungal biofilm formation regardless of the anti-fungal agent concentration (median absorbance for high-dose Al2O3-enhanced polymer coating was 0.176 [IQR = 0.207] versus control absorbance of 0.805 [IQR = 0.381], p = 0.003 [98% biofilm reduction]; median absorbance for high-dose TiO2-enhanced polymer coating was 0.186 [IQR = 0.024] versus control absorbance of 0.766 [IQR = 0.458], p < 0.001 [93% biofilm reduction]). Furthermore, synergy was revealed when the Bliss model was applied. According to the findings of this work, it seems that simultaneous consideration of Al2O3 and TiO2 could further increase the existing antibiofilm potential of these nanomaterials and decrease the likelihood of localized toxicity.

Abstract
BACKGROUND Various factors can affect the survival of patients with laryngeal cancer (LC). In this retrospective study, we assessed clinicopathological features, their prognostic value, and treatment modalities for patients with confirmed squamous cell LC. METHODS We collected patient data on demographics, clinicopathological characteristics, treatment patterns, and outcomes. The primary endpoints were overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), and locoregional control (LRC). We assessed survival using the Kaplan-Meier method and Cox regression model analyses of potential prognostic parameters. RESULTS After a median follow-up of 76 months, 28 (33.3%) patients had a recurrence. The median OS was 78 months, with an event recorded in 50% of patients. The DSS median was not reached (NR) with a survival rate of 72.6%, the DFS survival rate was 66.7% with median NR, and the LRC survival rate was 72.6% with median NR. After conducting a multivariate analysis of significant variables, we found that only recurrence and lymphatic invasion had an independent effect on OS and recurrence in DSS, while subsite impacted DFS and LRC. CONCLUSIONS Survival trends were consistent with other studies, except for OS. Recurrence, lymphatic invasion, and subsite location were significant factors that impacted patient survival.

Abstract
Approximately 60% of patients with squamous cell carcinoma (LSCC) have regional occult metastatic disease/distant metastases at the time of diagnosis, putting them at higher risk for disease progression. Therefore, biomarkers are needed for early prognostic purpose. The aim of this study was to analyze the expression pattern of connexins (Cx) 37, 40 and 45, pannexin1 (Panx1) and vimentin in LSCC and correlate with tumor grade (G) and outcome. METHODS Thirty-four patients who underwent (hemi-)laryngectomy and regional lymphadenectomy due to LSCC from 2017 to 2018 in University Hospital Split, Croatia, were studied. Samples of tumor tissue and adjacent normal mucosa embedded in paraffin blocks were stained using the immunofluorescence method and were semi-quantitatively analyzed. RESULTS The expression of Cx37, Cx40, and Panx1 differed between cancer and adjacent normal mucosa and between histological grades, being the highest in well-differentiated (G1) cancer and low/absent in poorly differentiated (G3) cancer (all p < 0.05). The expression of vimentin was the highest in G3 cancer. Expression of Cx45 was generally weak/absent, with no significant difference between cancer and the controls or between grades. Lower Panx1 and higher vimentin expression were found to be prognostic factors for regional metastatic disease. Lower Cx37 and 40 expressions were present in patients with disease recurrence after the three-year follow-up period. CONCLUSION Cx37 and Cx40, Panx1, and vimentin have the potential to be used as prognostic biomarkers for LSCC.

Cell Cycle-Related Gene SPC24: A Novel Potential Diagnostic and Prognostic Biomarker for Laryngeal Squamous Cell Cancer. BIOMED RESEARCH INTERNATIONAL 2023; 2023:1733100. [PMID: 36718148 PMCID: PMC9884166 DOI: 10.1155/2023/1733100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 10/02/2022] [Accepted: 12/27/2022] [Indexed: 01/22/2023]
Abstract
Laryngeal squamous cell cancer (LSCC) is a common malignant tumor with a high degree of malignancy, and its etiology remains unclear. Therefore, screening potential biomarkers is necessary to facilitate the treatment and diagnosis of LSCC. Robust rank aggregation (RRA) analysis was used to integrate two gene expression datasets of LSCC patients from the Gene Expression Omnibus (GEO) database and identify differentially expressed genes (DEGs) between LSCC and nonneoplastic tissues. A gene coexpression network was constructed using weighted gene correlation network analysis (WGCNA) to explore potential associations between the module genes and clinical features of LSCC. Combining differential gene expression analysis and survival analysis, we screened potential hub genes, including CDK1, SPC24, HOXB7, and SELENBP1. Subsequently, western blotting and immunohistochemistry were used to test the protein levels in clinical specimens to verify our findings. Finally, four candidate diagnostic and prognostic biomarkers (CDK1, SPC24, HOXB7, and SELENBP1) were identified. We propose, for the first time, that SPC24 is a gene that may associate with LSCC malignancy and is a novel therapeutic target. These findings may provide important mechanistic insight of LSCC.

Abstract
Among malignant tumors, lung adenocarcinoma (LUAD) is the leading cause of death worldwide. This study explored the diagnostic, prognostic value, and preliminary functional verification of sialic acid binding Ig like lectin 17, pseudogene (SIGLEC17P) in LUAD. Prognostic lncRNAs for LUAD were identified by The Cancer Genome Atlas and quantitative real-time PCR (qRT-PCR) was used to detect the expression of SIGLEC17P in LUAD and paracarcinoma tissues. Subsequently, lentiviral vectors were used to overexpress SIGLEC17P in A549 and H1299 cells. The effects of SIGLEC17P overexpression on the proliferation, migration, and invasiveness of LUAD cells (A549 and H1299) were evaluated by Cell Counting Kit-8, wound healing, and transwell migration assays, respectively. Bioinformatics analyses were performed to reveal the potential pathways in which SIGLEC17P is involved in LUAD. qRT-PCR results revealed low SIGLEC17P expression in LUAD tissues and a significant association with the N stage, T stage, and tumor node metastasis stage. Furthermore, the receiver operating characteristic curve demonstrated a reliable diagnostic value. The proliferation, migration, and invasion of LUAD cells were inhibited by overexpression of SIGLEC17P. Bioinformatics analyses suggested that SIGLEC17P might exert antioncogenic effects in LUAD through the mir-20-3p/ADH1B or mir-4476-5p/DPYSL axis. In summary, our results revealed that SIGLEC17P acts as a prognostic biomarker, independent prognostic factor, and potential therapeutic target for patients with LUAD.

Abstract
Exosomes are a new way of the communication between the tumor cell and macrophage in the micro-environment. The macrophage can be induced to different phenotypes according to the different tumors. In the present study, long-chain noncoding RNA HOTAIR (lncRNA HOTAIR) was highly expressed in LSCC and exosomes. The pathway of exosomal lncRNA HOTAIR inducing macrophage to M2 polarization in the LSCC was investigated. The carcinoma tissues and adjacent tissues were collected from 104 LSCC cases, and the positive relationship between CD163-/CD206-M2 macrophage infiltration and clinical phase, lymph node spreading and pathological phase in LSCC was observed. To examine the role of exosomal lncRNA HOTAIR, macrophages were co-cultured with LSCC-exosomes of high lncRNA HOTAIR expression or transferred with HOTAIR mimics. It was suggested that exosomal lncRNA HOTAIR can induce macrophages to M2 polarization by PI3K/p-AKT/AKT signaling pathway. Furthermore, exo-treated M2 macrophages facilitate the migration, proliferation, and EMT of LSCC.

CLINICAL LINGUISTICS & PHONETICS 2022:1-16. [PMID: 35656723 DOI: 10.1080/02699206.2022.2059398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 03/23/2022] [Accepted: 03/24/2022] [Indexed: 06/15/2023]
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
Laryngeal carcinoma is the most common malignant tumor of the upper respiratory tract. Total laryngectomy provides complete and permanent detachment of the upper and lower airways that causes the loss of voice, leading to a patient's inability to verbally communicate in the postoperative period. This paper aims to exploit modern areas of deep learning research to objectively classify, extract and measure the substitution voicing after laryngeal oncosurgery from the audio signal. We propose using well-known convolutional neural networks (CNNs) applied for image classification for the analysis of voice audio signal. Our approach takes an input of Mel-frequency spectrogram (MFCC) as an input of deep neural network architecture. A database of digital speech recordings of 367 male subjects (279 normal speech samples and 88 pathological speech samples) was used. Our approach has shown the best true-positive rate of any of the compared state-of-the-art approaches, achieving an overall accuracy of 89.47%.

Abstract
PURPOSE Advanced-stage laryngeal cancer is a challenging disease that needs multimodal treatment. Medical and surgical organ-preservation strategies have been developing in the last decades to spare these functions while granting cancer cure. The current work presents the experience of a tertiary-care center in conservative surgery for advanced-stage laryngeal cancer. MATERIALS AND METHODS We collected clinical data of patients submitted to open partial horizontal laryngectomies (OPHLs) and any possible adjuvant treatment from 2005 to 2018. Outcomes were also compared to the most recent studies reporting on both medical and surgical organ-preservation strategies. RESULTS One hundred ten patients were included in the analysis. Adjuvant therapy was employed in 51% of cases. The local control rate was 96.4%, while overall survival (OS) was 67%, and laryngo-esophageal dysfunction free survival (LEDFS) was 66%. Stage IV and vascular invasion were associated with a statistically-significant worse survival. CONCLUSIONS OPHLs are valid as upfront treatment in fit patients affected by advanced-stage laryngeal cancer. Disease control and function preservation are granted in a significant percentage of cases, even when followed by adjuvant therapy.

Abstract
Abstract
Recently, the incidence rate of head and neck cancer (HNC) has been increasing significantly. It is estimated that there are over 550,000 new cases per year, of which over 130,000 are laryngeal cancers. It is assumed that in more than 60% of patients the disease is diagnosed late, at stages III–IV, which is associated with unfavorable prognoses: the average survival ranges from 15% to 45%. The mainstay of successful tumor therapy is the early detection of neoplastic tissue. The laryngological examination with the use of traditional instruments should be expanded with an endoscopic examination of the larynx using optics in the outpatient clinics. This procedure is sufficient to select patients who need a direct laryngoscopy with a surgical biopsy, usually under general anesthesia in operating room conditions. However, it may bear potential complications. In 1941, Papanicolaou and Traut showed that brush cytology could be useful in detecting precancerous conditions and cervical cancers. For decades, research on the usefulness of brush cytology in diagnosing precancerous conditions and laryngeal cancers has been conducted. This paper aims to enable the reader to understand the issues related to laryngeal cancer and present the results of the previous use of brush cytology in the diagnostic process.

Abstract
Importance Pharyngocutaneous fistula (PCF) is a serious complication after total laryngectomy. Despite the well-described clinical risk factors for PCF and its association with poor quality of life, there is a paucity of data on the nonclinical factors that may be associated with this complication. Objective To determine whether nonclinical risk factors (eg, age, sex, race and ethnicity) are associated with an increased risk of developing a PCF after total laryngectomy, and whether or not the method of reconstruction explains any differences found. Design, Setting, and Participants This retrospective multicenter cohort study used data from a nationally validated, risk-adjusted, outcomes-based, surgical quality improvement database (the National Surgical Quality Improvement Program) to examine outcomes in patients who underwent a total laryngectomy from 2005 to 2018. The database was queried from January 1, 2005, to December 31, 2018; data analyses were performed from September 1, 2020, to March 31, 2021. Main Outcomes and Measures The primary outcome was development of a PCF within 30 days of a total laryngectomy. Patient characteristics, including age, sex, race and ethnicity, comorbidities, and mode of reconstruction, were analyzed. Results A cohort of 1573 adult patients (median age [IQR], 63 [56-71] years; 1280 [81.4%] men; 293 [18.6%] women; 1001 [63.6%] non-Hispanic White individuals) had undergone a total laryngectomy during the study period and were included in the analyses. The overall rate of PCF formation was 4.3% (68 of 1573 patients). Hispanic patients had the highest rate (9.5%; 9 of 95 patients) of PCF formation, which was more than twice the rate among non-Hispanic White patients (3.8%; 38 of 1001) and non-Hispanic Black patients (4.7%; 11 of 236). After adjusting for clinical and other covariates, women were 1.9 times more likely to develop a PCF compared with men (adjusted odds ratio, 1.90; 95% CI, 1.08-3.35). We also found that the odds of developing a PCF were 3-fold higher among Hispanic patients compared with non-Hispanic White patients (adjusted odds ratio, 2.96; 95% CI, 1.36-6.47). The type of reconstruction did not differ across age or race and ethnicity after controlling for clinical risk factors. Conclusions and Relevance This multicenter cohort study found that 2 nonclinical risk factors-Hispanic ethnicity and female sex-were associated with an increased risk of PCF formation. Knowledge of these risk factors should be included in patient-physician decision-making as well as future interventions to decrease the rate of PCF formation after laryngectomy.

Abstract
This study aimed to investigate the potential application of ceragenins (CSAs) as new candidacidal agents to prevent biofilm formation on voice prostheses (VPs). The deterioration of the silicone material of VPs is caused by biofilm growth on the device which leads to frequent replacement procedures and sometimes serious complications. A significant proportion of these failures is caused by Candida species. We found that CSAs have significant candidacidal activities in vitro (MIC; MFC; MBIC), and they effectively eradicate species of yeast responsible for VP failure. Additionally, in our in vitro experimental setting, when different Candida species were subjected to CSA-13 and CSA-131 during 25 passages, no tested Candida strain showed the significant development of resistance. Using liquid chromatography–mass spectrometry (LC-MS), we found that VP immersion in an ethanol solution containing CSA-131 results in silicon impregnation with CSA-131 molecules, and in vitro testing revealed that fungal biofilm formation on such VP surfaces was inhibited by embedded ceragenins. Future in vivo studies will validate the use of ceragenin-coated VP for improvement in the life quality and safety of patients after a total laryngectomy.

Abstract
This study aimed to explore the effect of programmed death-ligand 1 (PD-L1) in
cancer-associated fibroblasts (CAFs) on advanced laryngeal squamous cell
carcinoma (LSCC). The expression of PD-L1 in advanced LSCC tumor tissues was
observed in 83 patients with LSCC by immunofluorescence microscopy and compared
with that in normal laryngeal mucosa. The CAFs of LSCC and normal fibroblasts
(NFs) were isolated, cultured, purified, and examined by fluorescence. The
expression of PD-L1 in purified CAFs and NFs was measured by flow cytometry. The
expression of PD-L1 in CAFs was downregulated through small interferring RNA
(siRNA) transfection. The proliferation and migration capacities of CAFs were
observed using proliferation and scratch tests, respectively. The proliferation
of HEP-2 cells and T cells was measured after cocultured with CAFs. The
secretion of interleukins IL-2 and IL-10 was detected using enzyme-linked immuno
sorbent assay (ELISA). PD-L1 was expressed in 62 of 83 cases of the advanced
LSCC tumor tissues. Also, CAFs expressed more PD-L1 compared with NFs. The
proliferation and migration capacities of CAFs were significantly lower after
transfection with PD-L1-siRNA. The proliferation rate of HEP-2 cells cocultured
with CAFs decreased in PD-L1-siRNA-transfected cells. However, the proliferation
rate of T cells increased in transfected cells. The ELISA results showed that
the secretion of IL-2 increased and that of IL-10 decreased in
PD-L1-siRNA-transfected cells. The expression of PD-L1 in CAFs of advanced LSCC
was higher than that in NFs. The downregulation of PD-L1 reduced the
proliferation and migration of CAFs and HEP-2 cells but enhanced the
proliferation and pro-inflammatory function of T cells in the coculture
experiment.

Abstract
Forkhead box (FOX) proteins are multifaceted transcription factors that have been shown to be involved in cell cycle progression, proliferation and metastasis. FOXP4, a member of the FOX family, has been implicated in diverse biological processes in tumor initiation and progression. However, the molecular mechanisms of FOXP4 in laryngeal squamous cell carcinoma (LSCC) remain unknown. In the present study, differentially expressed transcripts in transforming growth factor‑β‑treated TU177 cells were screened using microarrays and it was found that FOXP4 was significantly upregulated. The high expression of FOXP4 was detected in LSCC tissues and cells, and predicted poor prognosis. The role of FOXP4 in laryngeal cancer cell proliferation, migration and invasion was determined by gain‑ and loss‑of‑function assays. Besides, FOXP4 was demonstrated to participate in the epithelial‑mesenchymal transition process at the mRNA and protein levels. Mechanically, FOXP4 directly bound to the promoter of lymphoid enhancer‑binding factor 1 and activated Wnt signaling pathway, which was confirmed via chromatin immunoprecipitation and luciferase reporter assays. Consequently, these findings provided novel mechanisms of FOXP4 in LSCC progression, which may be considered as potential therapeutic and prognostic targets for LSCC.

Abstract
ABSTRACT Laryngeal squamous cell cancer (LSCC) is the second most common head and neck cancer with the increasing mortality. The tyrosine kinase 2 (TYK2) has previously been reported to play an important role in various cancers excepting LSCC. We used available data from the cancer genome atlas program (TCGA), gene expression omnibus, and gene expression profiling interactive analysis (GEPIA) to evaluate the role of TYK2 in LSCC.The difference of TYK2 expression level between normal and tumor samples was analyzed based on TCGA, gene expression omnibus, and GEPIA databases. The relationship between clinical features and TYK2 were analyzed using the Wilcoxon signed-rank test. We applied Cox regression and the Kaplan-Meier method to finding which clinical characteristics is associated with overall survival. Also, we used GEPIA database to validate the relationship between TYK2 and overall survival. At last, we performed gene set enrichment analysis based on TCGA data set.The expression level of TYK2 in LSCC was significantly associated with gender, lymph node status and metastasis (P-values <.05). Kaplan-Meier survival analysis, as same as GEPIA validation, demonstrated that LSCC with TYK2-low had a worse prognosis than that with TYK2-high. The univariate analysis showed that TYK2-high correlated significantly with a better overall survival (hazard ratio: 0.351, 95% confidence interval: 0.194-0.637, P < .001). The multivariate analysis revealed that TYK2 remained independently associated with overall survival (hazard ratio: 0.36, 95% confidence interval: 0.185-0.699, P = .003). Gene set enrichment analysis shows that Janus kinases-STAT signaling pathway, p53 signalling pathway and natural killer cell mediated cytotoxicity, etc are enriched in TYK2 high expression phenotype.Gene TYK2 may be a potential prognostic molecular marker for LSCC. Moreover, the Janus kinases-STAT signaling pathway and p53 signaling pathway are probably the key pathway associated with TYK2 in LC.

Prognostic Significance of Vocal Cord Mobility after Laryngeal Preservation Protocols in Locally Advanced Laryngopharyngeal Cancers: A Retrospective Analysis. Indian J Otolaryngol Head Neck Surg 2021; 73:207-211.

Abstract
In the present study, we look at the prognostic implications of the recovery of vocal cord mobility after treatment in T3 laryngeal and hypopharyngeal cancers with fixed vocal cords. Patients with T3 laryngeal and hypopharyngeal carcinoma were considered for the study. All patients were treated with standard laryngeal preservation protocols as per treatment guidelines. Recovery of vocal cord functions was assessed with serial flexible laryngoscopic evaluation. Recovery of vocal cord mobility was compared with oncological outcomes. Twenty seven patients were available for final analysis. Cases, where vocal cords remained fixed or continued to have restricted mobility on follow up, were categorised as "unfavourable" and those with complete recovery of function as compared to pre treatment FOL as "Favourable". Thirteen (48%) patients did not regain complete mobility of vocal cords. Six patients from the 'unfavourable' group (46%) developed recurrence, whereas only one patient from the 'favourable' group (7%) had a recurrence (p = 0.03). The findings of the present study suggest that failure to regain complete vocal cord mobility after CTRT is a poor prognostic factor in T3 laryngeal and hypopharyngeal cancers.

Abstract
Introduction: Viral diseases can have roles in oral cavity and larynx carcinoma. However, the relationship between HPV, herpetic infection and these cancers is not clear. Materials & methods: DNA of tissues from oral and larynx carcinoma was extracted and the presence of HPV, HSV-1, HSV-2, EBV, CMV and Varicella Zoster virus was detected. Results: We detected five HSV-1 in oral cavity cancer and two HSV-1 in larynx carcinoma. Also, four and two HPV-positive in oral cavity and larynx carcinoma were found, respectively. There were five HPV type 18 and one HPV type 31. None of our samples were infected with EBV, CMV, HSV-2 and Varicella Zoster virus. Conclusion: A higher prevalence of HPV and HSV-1 in cancerous tissues in comparison with normal ones was detected.

Abstract
Objective To explore the survival value of lymph node dissection (LND) in elderly patients with T3-T4 laryngeal cancer, analyze the risk factors of lymph node metastasis, and construct a preoperative prediction model. Materials and Methods The study included 996 patients aged ≥65 years with laryngectomy confirmed T3-T4 laryngeal cancer queried from Surveillance, Epidemiology and End Results (SEER) database between 2010 and 2017. Propensity score matching (PSM) was applied to balance the effects of confounding factors. Kaplan–Meier (K–M) analysis and competitive risk model were used to compare the overall survival (OS) and cancer-specific survival (CSS) between LND and no-LND (N-LND) group. Combined with risk factors of multivariate logistic regression, a nomogram was built to predict lymph node metastasis preoperatively. The performance was assessed in the training set and the validation set, and internal validation was assessed. Results Among the cohort, 822 patients underwent LND and 410 patients had positive lymph nodes. The OS and CSS of patients who underwent LND were not better than that of N-LND patients (P>0.05). The prognosis of patients with lymph node metastases was significantly worse than that of negative patients (P<0.05). On multivariate logistic regression, supraglottis cancer, tumor size >5cm and grade 3–4 classification were associated with significantly greater odds of lymph node metastasis. The nomogram showed favorable predictive efficacy and good calibration (in the training cohort C-index=0.700; in the validation cohort C-index=0.721). Conclusion For elderly patients with T3-T4 laryngeal cancer, LND did not bring significant survival values. Supraglottis cancer, tumor size >5cm and grade 3–4 classification were independent risk factors of lymph node metastasis, which means poor prognosis. The nomogram developed was an easy-to-use tool for lymph node prediction.

Impact of Prior Cancer on the Prognosis of Patients With Laryngeal Cancer: A Population-Based Study Using the Surveillance, Epidemiology, and End Results Database. Front Oncol 2020; 10:561330.

Abstract
Background: Little is known about the clinical significance of laryngeal cancer as a subsequent tumor. We aimed to determine the impact of a prior cancer history on the prevalence and prognosis of patients with laryngeal cancer. Methods: We retrospectively reviewed patients diagnosed with laryngeal cancer between 2004 and 2011 in the Surveillance, Epidemiology, and End Results (SEER) database. The t-test and chi-squared test were used to compare variables as appropriate. Matched 1:1 case control-adjusted Kaplan-Meier analyses and Cox regression models were performed to investigate the impact of prior cancer on overall survival (OS). Results: Among 20,987 patients with laryngeal cancer, nearly one-fifth (n = 3,915, 18.65%) had a prior cancer. The top three common prior cancers were prostate (588, 28.1%), lung and bronchus (354, 16.9%), and head and neck (306, 14.6%). A total of 73.4% of the prior cancers were diagnosed within 5 years of the laryngeal cancer diagnosis. Compared to patients without prior cancer, a worse survival was significantly associated with a prior cancer among laryngeal cancer patients, regardless of the interval time of the prior cancer (log-rank tests P < 0.001). Furthermore, prior cancer was an independent predictor of worse OS based on the Cox regression model [hazard ratio (HR) = 1.396, 95% confidence interval, 1.336-1.458]. In addition, patients with prior lung and bronchus cancer tended to have the worst survival (log-rank tests P < 0.001). Conclusions: Prior cancer has an adverse effect on clinical outcomes among patients with laryngeal cancer. These results suggest that individualized treatment should be seriously considered in patients with laryngeal cancer and a history of prior cancer, regardless of the interval time of prior cancer.

Abstract
Spindle and kinetochore-associated complex subunit 3 (SKA3) is a well-known regulator of chromosome separation and cell division, which plays an important role in cell proliferation. However, the mechanism of SKA3 regulating tumor proliferation via reprogramming metabolism is unknown. Here, SKA3 is identified as an oncogene in laryngeal squamous cell carcinoma (LSCC), and high levels of SKA3 are closely associated with malignant progression and poor prognosis. In vitro and in vivo experiments demonstrate that SKA3 promotes LSCC cell proliferation and chemoresistance through a novel role of reprogramming glycolytic metabolism. Further studies reveal the downstream mechanisms of SKA3, which can bind and stabilize polo-like kinase 1 (PLK1) protein via suppressing ubiquitin-mediated degradation. The accumulation of PLK1 activates AKT and thus upregulates glycolytic enzymes HK2, PFKFB3, and PDK1, resulting in enhancement of glycolysis. Furthermore, our data reveal that phosphorylation at Thr360 of SKA3 is critical for its binding to PLK1 and the increase in glycolysis. Collectively, the novel oncogenic signal axis "SKA3-PLK1-AKT" plays a critical role in the glycolysis of LSCC. SKA3 may serve as a prognostic biomarker and therapeutic target, providing a potential strategy for proliferation inhibition and chemosensitization in tumors, especially for LSCC patients with PLK1 inhibitor resistance.

Oncol Rep 2020; 44:2031-2044.

Abstract
Long non‑coding (lnc)RNAs have been found to play a crucial role in tumor progression. The present study aimed to investigate the association between lncRNA RASSF8‑AS1 and laryngeal squamous cell carcinoma (LSCC) and the underlying mechanisms. Reverse transcription‑quantitative PCR was used to measure the mRNA expression level of RASSF8‑AS1, microRNA(miR)‑664b‑3p and transducin‑like enhancer of split 1 (TLE1) in LSCC. The associations between RASSF8‑AS1 and miR‑664b‑3p, and between miR‑664b‑3p and TLE1 were investigated using a dual luciferase reporter assay, while the former was further verified using an RNA immunoprecipitation (RIP) assay. The association between RASSF8‑AS1 and miR‑664b‑3p on cell biological functions was investigated in vitro using MTS, colony formation and Transwell assays. The RASSF8‑AS1 mRNA expression level was decreased in LSCC cell lines and carcinoma tissues, while overexpression of RASSF8‑AS1 reduced the migration, invasion and proliferation abilities of LSCC cells. Furthermore, luciferase and RIP assays confirmed that RASSF8‑AS1 was a competitive endogenous (ce)RNA by sponging miR‑664b‑3p to activate TLE1. miR‑664b‑3p was negatively modulated by RASSF8‑AS1; however, TLE1 was positively regulated by RASSF8‑AS1. Functionally, RASSF8‑AS1 acted as a ceRNA to upregulate TLE1 by sponging miR‑664b‑3p. In conclusion, the RASSF8‑AS1/miR‑664b‑3p/TLE1 axis acts by suppressing LSCC progression and may provide a novel insight for the molecular mechanism of LSCC.

Abstract
Simple Summary Epidemiological studies have shown that individual susceptibility to cancer is mediated by genetic and environmental factors. The aim of the present study is to evaluate the individuals’ metabolic genetic susceptibility to toxic habits (smoking and alcohol consumption) by detecting polymorphisms CYP1A1 rs1048943 T>C and CYPA1A2 rs4646903 A>G, and null polymorphisms in GSTM1 and GSTT1 genotypes, comparing a group of healthy control subjects with a population of larynx cancer patients from southeastern Spain. As results patients with larynx cancer present more gene GSTM1 and GSTT1 null polymorphisms, and CYP1A1 rs4646903 T>C polymorphisms. Abstract Background: some types of cancer have been associated with the presence of single nucleotide polymorphisms (SNPs) of some genes that encode enzymes: glutathione-S transferase (GST), whose alteration leads to loss of function and a lower capacity to eliminate toxic GSTM1 and GSTT1 null genotypes; SNPs causing loss of function of CYP1A1 or CYP1A1–2 cytochrome P450 enzymes related with a lower capacity to deactivate hydrocarbons related to smoking, which involves a higher risk of developing some smoking-dependent cancers including larynx cancer. Objective: to compare the presence of null SNPs in genes GSTM1, GSTT1, and CYP1A1 rs 4646903 T>C, and CYP1A1–2 RS1048943 A>G in patients with hypopharyngeal and larynx cancer with a healthy control group. Materials and method: The study included a total of 80 patients with hypopharyngeal and laryngeal cancer and 23 healthy subjects. Genomic DNA was obtained from saliva samples, determining genotype GSTM1 (present +, or null −), GSTT1 (present + or null −). Polymorphisms (SNP) in CYP1A1 T>C (present + CC, or absent − TC/TT), and CYP1A1–2 A>G (present + GG, or absent − AG/AA). Results: the mean age of patients with larynx cancer was 62 years and of control subjects 63 years. Of the total sample, over 95% were men, and over 90% were smokers. The presence of null genotypes for GTM1 was 50% in patients with larynx cancer (p = 0.042), while GSTT1 was 88.75% (p = 0.002). CYP1A1 rs4646903 T>C polymorphisms were detected in 100% of cases of larynx cancer and 17.39% of healthy subjects (p > 0.001). Conclusions: patients with larynx cancer present more gene GSTM1 and GSTT1 null polymorphisms, and CYP1A1 rs4646903 T>C polymorphisms.

Abstract
The aim of this comprehensive review is to describe and analyze the role of the sentinel node mapping in head and neck cancers. For this purpose, head and neck neoplasms have been categorized in cutaneous malignancies and neoplasms of the upper aerodigestive tract. A concise description of lymphatic drainage will be the "prelude" for each section, as well as the description of the injection techniques, when specific. Concisely, the attention has been focused on detection rate of the sentinel node by lymphoscintigraphy for each cancer, and for those patients in which the sentinel lymph node has been identified, true-positives rates, false-negative rates, and overall accuracy has been pointed out. Overall, in cutaneous neoplasms of the head and neck, the detection rate is higher than 90%, however the false-negative rate is still an issue, in particular in melanoma, inducing the need for newer developments. In fact, new tracers and techniques are already available, while prospective multicenter trials exploring the outcome impact are needed in the near future. For the upper aerodigestive tract and in particular oral cavity and oropharynx, sentinel lymph node identification by lymphoscintigraphy allows avoiding unnecessary neck dissection and/or node irradiation. Even in this case, the main limit remains the risk of false-negative rates. While, for patients affected by laryngeal and hypopharyngeal cancers the data seem very limited and, although the feasibility has been demonstrated, performances of this lymphoscintigraphy still need to be confirmed by multicenter studies.

Abstract
At present, no blood-based biomarkers have been used in clinical practice for laryngeal squamous cell carcinoma (LSCC). Increasing evidence suggests that circulating exosomal microRNAs (miRNAs) may serve as potential diagnostic biomarkers for various cancers. This study aims to identify and evaluate serum exosomal miRNAs for LSCC diagnosis. The ExoQuick solution (EQ), which provides a high-yield and is a highly efficient exosome isolation method, was selected to isolate serum exosomes in the current study. In LSCC samples, exosome concentrations were higher than in healthy control (HC) samples. RNA-seq analysis identified a total of 1608 miRNAs, with 34 upregulated and 41 downregulated in LSCC samples relative to HC samples. Furthermore, qRT-PCR showed that miR-941 is significantly upregulated in LSCC serum exosomes, with this same trend seen in LSCC tissues and cells. Moreover, when examining miR-941 in cell lines, miR-941 overexpression promoted proliferation and invasion, while miR-941 knockdown inhibited cell proliferation and invasion. ROC curve analysis showed that miR-941 has an area under the curve (AUC) of 0.797 (95% CI = 0.676-0.918) for distinguishing LSCC patients from HCs. In conclusion, serum exosomal miR-941 may serve as a promising oncogenic biomarker for diagnosing LSCC, and has the potential as a therapeutic target.

Abstract
Because advanced laryngeal squamous cell carcinoma (LSCC) is diagnosed as a malignant tumor with a poor prognosis, the associated mechanisms still need to be further investigated. As key players in the development and progression of LSCC, lncRNAs have attracted increasing attention from many researchers. In this study, a novel lncRNA termed IGKJ2‐MALLP2 was identified and investigated for its effects on the development of LSCC. IGKJ2‐MALLP2 expression was confirmed by RT‐qPCR in 78 pairs of tissues and human laryngeal carcinoma cell lines. The results of this study showed that the expression of IGKJ2‐MALLP2 was reduced in LSCC tissues and displayed close relationships with tumor stage, lymph node metastasis, and clinical stage. Using a dual‐luciferase reporter assay, the ability of miR‐1911‐3p to bind both IGKJ2‐MALLP2 and p21 mRNA was demonstrated. IGKJ2‐MALLP2 could upregulate p21 expression by competitively binding miR‐1911‐3p. Moreover, IGKJ2‐MALLP2 effectively hindered the invasion, migration, and proliferation of AMC‐HN‐8 and TU212 tumor cells. Furthermore, its high expression could hinder the secretion of VEGF‐A and suppress angiogenesis. As revealed by the results of in vitro experiments, IGKJ2‐MALLP2 overexpression could restrict tumor growth and blood vessel formation in a xenograft model of LSCC. As indicated from the mentioned findings, IGKJ2‐MALLP2, which mediates p21 expression by targeting miR‐1911‐3p, was capable of regulating LSCC progression and could act as an underlying therapeutic candidate to treat LSCC.

Abstract
PURPOSE Immune scores have been used as a prognostic factor for various types of cancer. However, the association between immune scores and the prognosis of laryngeal squamous cell cancer (LSCC) has not yet been investigated. This study aimed to explore the prognostic significance of immune scores and construct a clinical nomogram to predict the survival of patients with LSCC. METHODS The clinicopathological characteristics and immune scores of 102 patients with LSCC were obtained from TCGA database and a nomogram was developed. C-index and calibration curves were applied to assess the performance of the model. RESULTS Patients with higher immune scores had significantly better overall survival (OS). The prognostic nomogram presented a good performance in survival prediction. CONCLUSIONS High immune scores are correlated with improved OS in patients with LSCC. In addition, the nomogram developed for this study may assist clinicians in the prognostic evaluation of patients with LSCC.

Comparison of long-term treatment outcomes of T2N0M0 laryngeal squamous cell carcinoma using different treatment methods. Oncol Lett 2020; 20:921-930. [PMID: 32566021 DOI: 10.3892/ol.2020.11628] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Accepted: 04/01/2020] [Indexed: 11/06/2022] Open
Abstract
Early [stage I and II (T2N0M0)] laryngeal cancer types are currently recommended to be treated with a single modality, consisting of definitive radiation therapy or larynx-preserving surgery. Although the treatment outcomes of stage I are good, the frequency of successful outcomes decreases with T2N0M0. Therefore, the present study investigated the treatment outcomes of different treatment methods in T2N0M0 laryngeal cancer. In total, 83 patients with previously untreated T2N0M0 laryngeal squamous cell carcinoma were enrolled. Patients were grouped by treatment method: Radiation therapy (RT; 27 patients); chemoradiotherapy (CRT; 46 patients) with cisplatin base; and surgery-based therapy (SBT; ten patients). The recurrence rates of the RT, CRT and SBT groups were 44.4, 19.6 and 50%, respectively. Moreover, the local control rates of the RT, CRT and SBT groups were 55.6, 87.0 and 80%, respectively. The CRT group had a significantly lower recurrence rate and higher local control rate compared with the RT group (P<0.05). In the survival analysis, overall and disease-specific survival rate did not differ significantly among the treatment groups. However, 3- and 5-year disease-free survival rates (DFS) of the RT group were both 55%, those of the SBT group were both 50% and those of the CRT group were both 80%. Furthermore, the DFS was significantly higher in CRT group compared with the other groups (P=0.02). Using multivariate analysis with Cox regression, it was found that the treatment method was the most important factor for DFS and had a significant impact in the CRT group. In addition, in patients with glottic cancer with anterior commissure and subglottic invasion, the CRT group had significantly improved DFS compared with the RT group, whereas there was no significant difference between the two groups in patients without subglottic invasion. According to National Cancer Institution Common Toxicity Criteria (version 5.0), more patients had toxicity in the CRT group compared with the RT group. However, in the RT and CRT groups, no patients demonstrated mortality due to toxicity, and treatment-related toxicities were manageable. Collectively, although definitive conclusions could not be established, due to the limitations of this retrospective study, the results suggest that CRT had a positive impact on the local control and DFS rates with manageable toxicity in patients with T2N0M0 laryngeal cancer.

Abstract
Purpose To date, no guidelines have been proposed for the ideal treatment of postoperative larynx squamous cell carcinoma (LSCC) patients with lymphovascular invasion due to a lack of similar studies. The present study was conducted to compare the survival and toxicity in LSCC patients with lymphovascular invasion receiving either postoperative radiotherapy (PORT) or postoperative chemoradiotherapy (POCRT). The results can be applied for more appropriate treatment of these patients. Patients and Methods Three hundred eighty-eight eligible LSCC patients with lymphovascular invasion were enrolled in this retrospective study. Survival and treatment-related toxicities were compared in the POCRT and PORT group using propensity score matching (PSM) methodology (1:1). Results Five-year overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) of all patients were 48.7%, 58.2%, and 56.0%, respectively. Significantly, higher RFS rates (P=0.040) were found in the POCRT group than the PORT group in the PSM cohort. In the multivariate analysis, higher OS, DSS, and RFS rates were observed in the POCRT group than the PORT group (P=0.049, 0.024, and 0.011 respectively). Patients in the POCRT group presented more acute toxicities than those in the PORT group such as hematological toxicities (25.0% vs 0.9%, P<0.001) and mucositis (35.0% vs 19.1%, P=0.002). Conclusion In the context of no ideal treatment for LSCC patients with lymphovascular invasion, the present study proposes POCRT as a preferable modality compared with PORT, as POCRT was associated with higher RFS rates. Higher RFS, DFS, and OS rates were also observed in the POCRT group in the multivariate analysis.

Abstract
MicroRNAs (miRNAs), a type of post-transcriptional regulators, exert a crucial role in the malignant progression of laryngeal squamous cell carcinoma (LSCC). MicroRNA-330-3p (miR-330-3p), a recently identified tumor-associated miRNA, is implicated in multiple cancers. Yet, the relevance of miR-330-3p in LSCC remains unexplored. The findings of our study demonstrated a lower expression of miR-330-3p in LSCC. Functional assays revealed that upregulation of miR-330-3p marked restricted the proliferation, colony formation and invasion of LSCC cells. Transformer-2 protein homolog beta (Tra2β) was identified as a target gene of miR-330-3p. An inverse correlation between miR-330-3p and Tra2β mRNA expression was evidenced in LSCC specimens. The upregulation of miR-330-3p significantly repressed Tra2β expression and the phosphorylation of the Akt protein. In addition, Tra2β overexpression markedly abrogated the tumor suppressive role of miR-330-3p in LSCC cells. Overall, our results uncovered that miR-330-3p exerted a tumor-inhibition function in LSCC through targeting Tra2β to inhibit Akt activation.

Abstract
Accumulating evidence indicates that lncRNAs can interact with miRNAs to regulate target mRNAs through competitive interactions. However, this mechanism remains largely unexplored in laryngeal squamous cell carcinoma (LSCC). In this study, transcriptome-wide RNA sequencing was performed on 3 pairs of LSCC tissues and adjacent normal tissues to investigate the expression profiles of lncRNAs, miRNAs and mRNAs, with differential expression of 171 lncRNAs, 36 miRNAs and 1709 mRNAs detected. Seven lncRNAs, eight mRNAs and three miRNAs were identified to be dysregulated in patients' tissues by using qRT-PCR. GO and KEGG pathway enrichment analyses were performed to elucidate the potential functions of these differentially expressed genes in LSCC. Subsequently, a ceRNA (lncRNA-miRNA-mRNA) network including 4631 ceRNA pairs was constructed based on predicted miRNAs shared by lncRNAs and mRNAs. Cis- and transregulatory lncRNAs were analysed by bioinformatics-based methods. Importantly, mRNA-related ceRNA networks (mRCNs) were further obtained based on potential cancer-related coding genes. Coexpression between lncRNAs and downstream mRNAs was used as a criterion for the validation of mRCNs, with the ZNF561-AS1-miR217-WNT5A and SATB1-AS1-miR1299-SAV1/CCNG2/SH3 KBP1/JADE1/HIPK2 ceRNA regulatory interactions determined, followed by experimental validation after siRNA transfection. Moreover, ceRNA activity analysis revealed that different activities of ceRNA modules existing in specific pathological environments may contribute to the tumorigenesis of LSCC. Consistently, both downregulated SATB1-AS1 and ZNF561-AS1 significantly promoted laryngeal cancer cell migration and invasion, indicating their important roles in LSCC via a ceRNA regulatory mechanism. Taken together, the results of this investigation uncovered and systemically characterized a lncRNA-related ceRNA regulatory network that may be valuable for the diagnosis and treatment of LSCC.

Abstract
Purpose Long noncoding RNAs (lncRNAs) have been identified as an important class of noncoding RNAs that are deeply involved in multiple biological processes in tumorigenesis. This study is to investigate the critical roles and biological function of lncRNA growth arrest-specific 5 (GAS5) in tumorigenesis of laryngeal squamous cell carcinoma (LSCC). Patients and methods A total of 59 samples of LSCC and paired adjacent tissue, as well as corresponding clinicopathological information were collected. GAS5 expression in both LSCC tissues and human SUN1076 and SNU899 cell lines were analyzed by Real-time quantitative RT-PCR method. Ectopic expression of GAS5 by vector transfection in LSCC cell lines and followed by in vitro experiments was to investigate the critical roles and function of GAS5 in LSCC. Cell Counting Kit 8 (CCK8) assay and PE/7AAD Annexin V Apoptosis analysis was to evaluate cell proliferation ability and cell apoptosis. Co-transfection of GAS5 and miR-21 was to explore the interaction between GAS5 and miR-21 in LSCC. BAX and CDK6 protein level were analyzed by western blot method. Results This study demonstrated that GAS5 was significantly downregulated in LSCC tissue and human LSCC cell lines. GAS5 levels were correlated with the clinicopathological features of LSCC patients. In addition, the ectopic expression of GAS5 significantly inhibited cell proliferation and promoted apoptosis. Co-expression analyses indicated that GAS5 is negatively correlated with miR-21 in LSCC tissues. Overexpression of miR-21 eliminated GAS5-mediated cell apoptosis and proliferation suppression. Furthermore, GAS5, which upregulated BAX mRNA expression and downregulated CDK6 mRNA expression, was reversed by ectopic expression of miR-21. Conclusion GAS5 suppresses LSCC progression through the negative regulation of miR-21 and its targets involved in cell proliferation and apoptosis, indicating that GAS5 may serve as a biomarker and potential target for LSCC therapy.

Abstract
Background Laryngeal squamous cell carcinoma (LSCC) is one of the most common malignant tumours of the head and neck. Recent evidence has demonstrated that lncRNAs play important roles in tumour progression and could be used as biomarkers for early diagnosis, prognosis, and potential therapeutic targets. The "competitive endogenous RNA (ceRNA)" hypothesis states that lncRNAs competitively bind to miRNAs through their intramolecular miRNA reaction elements (MREs) to construct a wide range of ceRNA regulatory networks. This study aims to predict the role of ceRNA network in LSCC, for advancing the understanding of underlying mechanisms of tumorigenesis. Material and Methods In this study, the functions of lncRNAs as ceRNAs in LSCC and their prognostic significance were investigated via comprehensive integrated expression profiles data of lncRNAs, mRNAs, and miRNAs obtained from The Cancer Genome Atlas (TCGA). Protein-protein interaction, gene ontology, pathway, and Kaplan-Meier curves analysis were used to profile the expression and function of altered RNAs in LSCC. Results As a result, 889 lncRNAs, 55 miRNAs and 1946 mRNAs were found to be differentially expressed in LSCC. These altered mRNAs were mainly involved in extracellular matrix organization, calcium signaling, and metabolic pathways. To study the regulatory function of lncRNAs, an lncRNA-mediated ceRNA network was constructed. This ceRNA network included 61 lncRNAs, seven miRNAs and seven target mRNAs. Of these RNAs, lncRNAs (TSPEAR-AS, CASK-AS1, MIR137HG, PART1, LSAMP-AS1), miRNA (has-mir-210) and mRNAs (HOXC13, STC2, DIO1, FOXD4L1) had a significant effect on the prognosis of LSCC. Conclusion The results of this study broaden the understanding of the mechanisms by which lncRNAs are involved in tumorigenesis. Furthermore, five lncRNAs (TSPEAR-AS, CASK-AS1, MIR137HG, PART1, LSAMP-AS1) were identified as potential prognostic biomarkers and therapeutic targets for LSCC. These results provide a basis for further experimental and clinical research.

Abstract
The use of data from the real world to address clinical and policy-relevant questions that cannot be answered using data from clinical trials is garnering increased interest. Indeed, data from cancer registries and linked treatment records can provide unique insights into patients, treatments and outcomes in routine oncology practice. In this Review, we explore the quality of real-world data (RWD), provide a framework for the use of RWD and draw attention to the methodological pitfalls inherent to using RWD in studies of comparative effectiveness. Randomized controlled trials and RWD remain complementary forms of medical evidence; studies using RWD should not be used as substitutes for clinical trials. The comparison of outcomes between nonrandomized groups of patients who have received different treatments in routine practice remains problematic. Accordingly, comparative effectiveness studies need to be designed and interpreted very carefully. With due diligence, RWD can be used to identify and close gaps in health care, offering the potential for short-term improvement in health-care systems by enabling them to achieve the achievable.

Abstract
Introduction
Epidemiological studies focused on prognostic factors associated with laryngeal cancer in the Brazilian population are poorly reported in the literature.
Objective
To evaluate the influence of certain risk factors on the survival rates of patients with squamous cell carcinoma (SCC) of the larynx.
Methods
This retrospective study was conducted on adult patients who were admitted to the outpatient clinic of the head and neck department in a tertiary care hospital. Evaluation of the influence of risk factors on the survival rates of patients registered in the hospital with laryngeal SCC was performed based on age, sex, initial stage, time of evolution, habits, educational levels and relapse and death. Overall survival (OS), disease-free survival (DFS) and clinical-demographic data were analyzed using the Kaplan-Meier method, Log-rank test and Cox regression.
Results
A total of 107 patients with a mean age of 59.8 years (range 19–81) were included in this study. Stages III and IV were associated with decreased DFS (
p
= 0.02) and OS (
p
= 0.02). Smoking patients had a greater period of disease evolution than non-smoking patients (
p
= 0.003). Alcohol consumption in smokers increased the risk of death by 2.8 (
p
= 0.002) compared with non-drinking smokers. Male patients presented lower DFS average when compared with female patients (
p
= 0.04).
Conclusion
Our study confirms that male gender, smoking habit combined with alcohol consumption, and advanced stages were strongly associated with poor prognosis.

Int J Oncol 2019; 54:2005-2018. [PMID: 31081043 PMCID: PMC6521927 DOI: 10.3892/ijo.2019.4784] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2018] [Accepted: 04/05/2019] [Indexed: 12/24/2022] Open
Abstract
Non‑coding RNAs, particularly long non‑coding RNAs (lncRNAs), play important roles in tumorigenesis. The miR‑155 host gene (MIR155HG) lncRNA has been found to play a crucial role in tumor progression. However, the role of MIR155HG in laryngeal squamous cell carcinoma (LSCC) remains unclear. Thus, the aim of the present study was to explore the roles and underlying molecular mechanisms of action of MIR155HG and miR‑155‑5p in LSCC, in an effort to provide novel approaches for the antitumor therapy for LSCC. In the present study, the expression levels of miR‑155‑5p and MIR155HG were detected by reverse tran-scription‑quantitative polymerase chain reaction. In addition, the biological functions of MIR155HG and miR‑155‑5p on LSCC were evaluated in vitro by MTS assay, colony formation assay and Transwell assays, and in vivo by tumorigenesis assays. It was revealed that MIR155HG and miR‑155‑5p were significantly upregulated in LSCC tissues, and were associated with the TNM stage, pathological differentiation and lymph node metastasis. Moreover, the knockdown of MIR155HG and miR‑155‑5p inhibited the proliferation, migration and invasion of LSCC cells, whereas their overexpression exerted the opposite effects in vitro and MIR155HG overexpression promoted tumorigenesis in vivo. Furthermore, MIR155HG downregulation reduced the expression level of miR‑155‑5p. The inhibitory effect of MIR155HG knockdown on malignant behavior was abrogated by miR‑155‑5p overexpression. Bioinformatics analysis and luciferase reporter assay confirmed that miR‑155‑5p contributed to the progression of LSCC by directly binding to the 3' untranslated region of SRY‑related‑HMG‑box 10 (SOX10). In addition, MIR155HG and miR‑155‑5p were upregulated by the induction of transforming growth factor‑β (TGF‑β) and promoted the expression of mesenchymal markers synergistically. On the whole, the findings of the present study indicate a novel role of MIR155HG in the TGF‑β‑induced EMT of LSCC cells by regulating EMT markers through the miR‑155/SOX10 axis. The MIR155HG/miR‑155‑5p/SOX10 axis plays an important role in promoting the progression of LSCC and may thus serve as a potential therapeutic target for LSCC treatment.

Abstract
OBJECTIVES/HYPOTHESIS The authors used the Surveillance, Epidemiology, and End Results (SEER) database to analyze epidemiological features of patients presenting with supraglottic squamous cell carcinoma (SCCa) and to evaluate treatment trends and outcomes. METHODS The SEER database was queried for patients with supraglottic SCCa from 1973 to 2013. Information on demographics; tumor size; histologic grade; American Joint Committee on Cancer (AJCC) stage; SEER local, regional, distant stage; and treatment modality were analyzed. RESULTS There were 22,675 cases of primary supraglottic SCCa identified. The mean age at diagnosis was 62.3 years, with males accounting for 70.3% of all cases. A high percentage of patients presented with stage IV disease (44.9%). The most common treatment modality was radiotherapy (46.6%), followed by combination of surgery and radiotherapy (29.2%) and surgery alone (15.0%). Overall 5-year disease-specific survival (DSS) for all cases was 54.0%. When stratified by treatment modality, 5-year DSS was best for patients receiving surgery alone (64.2%). However, for patients with AJCC stage IV disease, survival was significantly better with combined surgery and radiotherapy (52.5%). CONCLUSION In general, supraglottic SCCa is treated most commonly with radiotherapy, followed by surgery and radiotherapy. Patients managed surgically had better 5-year DSS when compared to patients treated by other modalities. However, when stratified by stage, patients with AJCC stage IV disease had significantly better survival with combined surgery and radiotherapy. Of patients receiving surgery, supraglottic laryngectomy was found to have a significantly better 5-year DSS when compared to both total laryngectomy and laryngectomy, not otherwise specified. LEVEL OF EVIDENCE NA Laryngoscope, 129:1822-1827, 2019.

Abstract
Background The survival outcomes between supracricoid partial laryngectomy (SCPL) and total laryngectomy (TL) were compared in the groups of matched-pair patients with T3 laryngeal squamous cell carcinoma (LSCC). Methods Patients with T3 LSCC were matched based on prognostic factors. The Kaplan–Meier curve and the Cox proportional hazards model were used for analysis on survival. Results A total of 212 patients with T3 LSCC were included after matching (106 underwent SCPL and 106 underwent TL). Multivariable analysis showed no differences in overall survival (hazard risk [HR]=1.15; 95% CI: 0.79–1.67; P=0.47), disease-specific survival (HR=1.11; 95% CI: 0.69–1.80; P=0.66), and recurrence-free survival (HR=1.07; 95% CI: 0.68–1.68; P=0.77) between the SCPL group and TL group. Conclusion SCPL provides reliable therapeutic outcomes and can be used to avoid a TL surgery in some patients with advanced primary laryngeal cancer.

Abstract
Laryngeal cancer is a frequent malignancy originating from the squamous vocal epithelium in a multi-stage fashion in response to environmental carcinogens. Although most cases can be cured by surgery and/or radiotherapy, advanced and relapsing disease is common, and biomarkers of such dismal cases are urgently needed. The cancer genome of laryngeal cancers was recently shown to feature a signature of aberrant nuclear factor (NF)-κB activation, but this finding has not been clinically exploited. We analyzed primary tumor samples of 96 well-documented and longitudinally followed patients covering the whole spectrum of laryngeal neoplasia, including 21 patients with benign laryngeal diseases, 15 patients with dysplasia, 43 patients with early-stage carcinoma, and 17 patients with locally advanced carcinoma, for immunoreactivity of RelA, RelB, P50, and P52/P100, the main NF-κB subunits that activate transcription. Results were cross-examined with indices of tumor progression and survival. Interestingly, RelB expression increased with tumor stage, grade, and local extent. Moreover, patients displaying high RelB immunoreactivity exhibited statistically significantly poorer survival compared with patients featuring low levels of RelB expression (P = 0.018 by log-rank test). Using Cox regression analyses and tumor stage, local extent, grade and RelA/RelB immunoreactivity, we develop a new score that can independently predict survival of patients with laryngeal cancer. Hence we provide a simple and affordable NF-κB-based test to predict prognosis in laryngeal cancer.

Abstract
Answer questions and earn CME/CNE Laryngeal cancer remains one of the most common tumors of the respiratory tract. Fortunately, significant advancements have been made over the past decade in the treatment of laryngeal cancer. Although surgery has been the historical mainstay for localized disease and still is an integral part of treatment, nonsurgical options like radiation and systemic therapy have emerged as viable options. In addition, in the metastatic setting, novel agents are showing promise for this patient population. The care for patients with laryngeal cancer continues to evolve and truly requires a multidisciplinary team-based approach. Unique morbidities, such as loss of natural voice, respiration, and airway protection during swallowing, are observed with this disease and require special consideration.

Abstract
BACKGROUND Radiotherapy is one of the main treatment modalities for early-stage glottic carcinoma. Unfortunately, local failure may occur in a group of cases with T1-T2 glottic carcinoma. This meta-analysis sought to determine risk factors for radiation failure in patients with early-stage glottic carcinoma. METHODS A systematic and comprehensive search was performed for related studies published between 1995 and 2014. The primary end-point was 5-year local control. Data extraction and analysis were performed using the software STATA/SE 13.1 for Windows. RESULTS Twenty-seven studies were eligible. A higher risk of radiation failure was demonstrated in male patients [relative risk (RR): 0.927, p<0.001] and those with low hemoglobin level (RR: 0.891, p<0.001) with a high agreement between studies (I-squared=0.0%). Moreover, T2 tumors (RR: 0.795, p<0.001), tumors with anterior commissure involvement (RR: 0.904, p<0.001), tobacco use during/after therapy (RR: 0.824, p<0.001), and "bulky" tumors (RR: 1.270, p<0.001] or tumors bigger in size (RR: 1.332, p<0.001]. Poorly differentiated tumors had a questionable risk of local failure, although a moderate to high interstudy heterogeneity was determined. A statistically significant contribution was not detected for age, presence of comorbidity, alcohol use or subglottic extension. CONCLUSION This is the first meta-analysis which assessed the potential risk factors for radiation failure in patients with early-stage glottic carcinoma. Gender and pretreatment hemoglobin level are major influential factors associated with radiation failure in patients with early-stage glottic carcinoma. However, prospective, randomized clinical trials may permit better stratification of their relative contributions, and those who may benefit more from upfront surgery.

Abstract
BACKGROUND Patterns of end-of-life cancer care differ in Canada and the United States; yet little is known about differences in service-specific and overall costs. AIM The aim of this study was to compare end-of-life costs in Ontario, Canada, and the United States, using administrative health data. DESIGN Advanced-stage nonsmall cell lung cancer patients who died from cancer at age ⩾ 65.5 years in 2001-2005 were selected from the US Surveillance, Epidemiology, and End Results-Medicare database (N = 16,858) and the Ontario Cancer Registry (N = 8643). We estimated total and service-specific costs (2009 US dollars) in each of the last 6 months of life from the public payer perspectives for short-term and long-term survivors (lived < 180 and ⩾ 180 days post-diagnosis, respectively). Services were defined for comparisons between systems. RESULTS Mean monthly costs increased as death approached, were higher in short-term than long-term survivors, and were generally higher in the United States than in Ontario until the month before death, when they were similar (long-term survivors: US$10,464 and US$10,094 (p = 0.53), short-term survivors US$14,455 and US$12,836 (p = 0.11), in Surveillance, Epidemiology, and End Results-Medicare and Ontario, respectively). Costs for Medicare hospice and Ontario's palliative care components were similar and increased closer to death. Inpatient hospitalization was the main cost driver with similar costs in both cohorts, despite lower utilization in the United States. The compositions of many services and costs differed. CONCLUSION Costs for nonsmall cell lung cancer patients were slightly higher in the United States than Ontario until 1 month before death. Administrative data allow exploration and international comparisons of reimbursement policies, health-care delivery, and costs at the end of life.

Abstract
BACKGROUND The current study was conducted to evaluate long-term disease control, survival, and functional outcomes after surgical and nonsurgical initial treatment for patients with T4 larynx cancer. METHODS Demographics, disease stage, and treatment characteristics were reviewed for 221 sequential patients treated for T4 laryngeal squamous cell cancer at a single institution between 1983 and 2011. Survival and disease control outcomes were calculated. RESULTS The median follow-up time was 47 months (71 months for patients still alive at the time of analysis). The overall 5-year and 10-year overall survival rates were 52% and 29%, respectively, and the corresponding disease-free survival rates were 57% and 48%, respectively. Overall 5-year and 10-year locoregional control rates were 78% and 67%, respectively, and the corresponding rates for freedom from distant metastasis were 76% and 74%, respectively. On both univariate and multivariate analyses, lymph node-positive disease at the time of presentation was associated with overall mortality (P<.0001). Patients treated with laryngectomy followed by postlaryngectomy radiotherapy (161 patients) achieved better initial locoregional control than patients treated with a laryngeal preservation (LP) approach (60 patients) throughout the follow-up period (log-rank P<.007) yet the median overall survival times were equal for both groups (64 months; 95% confidence interval 47-87 months and 38-87 months, respectively [P =.7]). Patients treated with an LP approach had a tracheostomy rate of 45% and an any-event aspiration rate of 23%. Rates of high-grade dysphagia at the time of last follow-up were worse for patients treated with an LP approach (P<.01). CONCLUSIONS Surgery and postoperative radiotherapy can produce substantial long-term cancer control and survival rates for patients with T4 larynx cancer. Caution should be taken when selecting patients for initial nonsurgical treatment because of significant rates of functional impairment despite survival equivalence.
