Combined PIK3CA and SOX2 Gene Amplification Predicts Laryngeal Cancer Risk beyond Histopathological Grading. Int J Mol Sci 2024; 25:2695.

Abstract
The PIK3CA and SOX2 genes map at 3q26, a chromosomal region frequently amplified in head and neck cancers, which is associated with poor prognosis. This study explores the clinical significance of PIK3CA and SOX2 gene amplification in early tumorigenesis. Gene copy number was analyzed by real-time PCR in 62 laryngeal precancerous lesions and correlated with histopathological grading and laryngeal cancer risk. Amplification of the SOX2 and PIK3CA genes was frequently detected in 19 (31%) and 32 (52%) laryngeal dysplasias, respectively, and co-amplification in 18 (29%) cases. The PIK3CA and SOX2 amplifications were predominant in high-grade dysplasias and significantly associated with laryngeal cancer risk beyond histological criteria. Multivariable Cox analysis further revealed PIK3CA gene amplification as an independent predictor of laryngeal cancer development. Interestingly, combined PIK3CA and SOX2 amplification allowed us to distinguish three cancer risk subgroups, and PIK3CA and SOX2 co-amplification was found the strongest predictor by ROC analysis. Our data demonstrate the clinical relevance of PIK3CA and SOX2 amplification in early laryngeal tumorigenesis. Remarkably, PIK3CA amplification was found to be an independent cancer predictor. Furthermore, combined PIK3CA and SOX2 amplification is emerging as a valuable and easy-to-implement tool for cancer risk assessment in patients with laryngeal precancerous lesions beyond current WHO histological grading.

Survival Analysis in Patients with Laryngeal Cancer: A Retrospective Cohort Study. Life (Basel) 2023; 13:life13020295. [PMID: 36836648 PMCID: PMC9965107 DOI: 10.3390/life13020295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 01/16/2023] [Accepted: 01/18/2023] [Indexed: 01/22/2023] Open
Abstract
INTRODUCTION The worldwide incidence rate of laryngeal cancer is declining. However, the 5-year survival for these patients has decreased in recent years from 66% to 63%. This may be due to changes in the treatment of the disease. The present study aimed to evaluate the survival rate of patients with LC according to the stage of the disease and the treatment applied. For this purpose, surgical versus organ preservation protocols (OPP) based on chemoradiotherapy were evaluated. METHODS A retrospective cohort study was conducted in a tertiary hospital. The study included adult patients with a clinical diagnosis of primary LC. Patients with LC and systemic metastases and those with synchronous tumors at diagnosis were excluded. Univariate and multivariate analyses were performed to determine the association between exposure to LC treatment and the time to event (death). Overall survival (OS), cause-specific survival (CSS), and disease-free survival (DFS) were calculated. RESULTS Patients with advanced tumors (stages III and IV) had almost three times the risk of LC death than those in the initial tumor stages (I and II) [HR CCS = 2.89 (95%CI 1.30-6.39)]; [HR OS = 2.01 (95%CI 1.35-2.98)]. Patients who underwent surgical treatment had a higher chance of survival than those who were treated according to OPP [HR = 0.62; 95%CI (0.38-1.02)] in CSS, 0.74 [95%CI (0.50-1.90)] in OS, and 0.61 [95%CI (0.40-0.91)] in DFS. DISCUSSION OPP changed the management of patients with advanced stages of LC, establishing CRT as an alternative to surgery. Our data did not reveal clinically relevant differences in OS between patients treated with OPP and those who underwent surgery; however, we reported differences in the DFS rate after five years of follow-up in favor of the surgery-treated group of patients. CONCLUSION Surgical treatment improves CSS and DFS at five years in patients with initial LC with respect to radiation therapy alone. Furthermore, surgical treatment associated with complementary radiation therapy offers better CSS and DFS in patients with advanced LC.

Abstract
Emerging evidence has revealed that aberrantly expressed circular RNAs (circRNAs) play vital roles in tumorigenesis and progression of diverse human malignancies. CircZNF609 was found to be involved in hepatocellular carcinoma, but the role and underlying mechanism of circZNF609 in laryngeal squamous cell carcinoma (LSCC) remain unclear. This study aimed to explore the molecular mechanism of circZNF609 in LSCC. qRT-qPCR was performed to detect the expression of circZNF609 and microRNA-134-5p (miR-134-5p) in LSCC. Colony formation assay, CCK-8 assay, BrdU incorporation assay, clone formation assay, transwell invasion assay and Western blot analysis were performed to evaluate LSCC cell proliferation, as well as the expression of proliferating cell nuclear antigen (PCNA) and MMP-2. Luciferase reporter assay, target gene prediction and screening were used to validate downstream target genes of circZNF609 and miR-134-5p. EGFR expression was detected by Western blot analysis and RT-qPCR. Nude mice were used to detect tumor changes. CircZNF609 was upregulated in LSCC and associated with poor survival of LSCC patients. Knockdown of circZNF609 inhibited LSCC proliferation, invasion and the expression of PCNA and matrix matalloproteinases-2 (MMP-2). CircZNF609 can regulate miR-134-5p to upregulate epidermal growth factor receptor (EGFR). In addition, knockdown of EGFR or overexpression of miR-134-5p could reverse the tumor-promoting effects of circZNF609 in LSCC. In LSCC tissues, circZNF609 was negatively correlated with miR-134-5p and positively correlated with EGFR. CircZNF609 promotes the progression of LSCC via the miR-134-5p/EGFR axis, which might be the therapeutic target of LSCC.

Abstract
Objectives This study aimed to explore the expression profile of the Forkhead box protein L2 gene (FOXL2) and to determine its prognostic value and associated epigenetic and genetic alterations in patients with laryngeal squamous cell carcinoma (LSCC). Materials and methods Data for a subset of patients with LSCC (N = 116) were extracted from the head and neck squamous cell carcinoma dataset of The Cancer Genome Atlas and analyzed in relation to FOXL2 expression and survival. Results Aberrant FOXL2 expression was an independent prognostic factor for progression-free survival (PFS) (hazard ratio (HR): 2.63, 95% confidence interval (CI): 1.34–5.18) and overall survival (OS) (HR: 2.39, 95%CI: 1.28–4.46). Two gene-body CpG sites (cg10554436 and cg23637494) were moderately and positively correlated with FOXL2 expression. DNA amplification (+2/+1) was common (82/115, 71%) in LSCC, and FOXL2 expression was significantly upregulated in the high-amplification group (+2) compared with copy-neutral (0) cases. Conclusion Aberrant FOXL2 expression may be a novel prognostic biomarker for PFS and OS among patients with LSCC. FOXL2 upregulation may be related to gene-body hypermethylation and DNA amplification.

Abstract
BACKGROUND/AIMS miR-802 plays a key role in cancer progression and development. The purpose of this work is to investigate the functional role of miR-802 in laryngeal cancer and to elucidate the function of miR-802 and cAMP-regulated phosphoprotein 19 (ARPP19) on laryngeal cancer. METHODS RT-qPCR was applied to study the expression level of ARPP19 and miR-802 in the laryngeal carcinoma cell lines and tissues. CCK-8, colony formation, flow cytometry (FACS) assay were used to study the effect of ARPP19 and miR-802 on apoptosis, proliferation, and cell cycle of laryngeal carcinoma cells. Target gene prediction and luciferase reporter gene assay were applied to identify target gene of miR-802. The transcriptional mRNA and protein expression levels of ARPP19 were measured by RT-qPCR or Western blotting. RESULTS miR-802 was down-regulated in laryngeal carcinoma cell lines and tissues. Laryngeal cancer cells transfected by miR-802 mimic were significantly inhibited in the terms of cell colony formation and proliferation. Furthermore, miR-802 can inhibit the expression level of ARPP19 by directly targeting the 3' untranslated region (3'-UTR) of ARPP19. Overexpression of the ARPP19 gene can reverse the suppressive effect of miR-802 on laryngeal cancer cells. CONCLUSION miR-802 can exert tumor suppressor effects in laryngeal carcinoma by targeting ARPP19, indicating that miR-802 protein may play a role of potential therapeutic target for clinical laryngeal cancer.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is currently a serious public health problem in China; thus, it is urgent to identify effective treatment strategies for this disease. Previous studies demonstrated that reactive oxygen species (ROS) serve important roles in the apoptosis of LSCC cells. It has also been indicated that carboplatin (CBDCA), a second-generation platinum compound with broad antineoplastic properties, is able to induce oxidative stress to produce ROS, which in turn promotes apoptosis. Thus, the present study investigated if CBDCA is cytotoxic in LSCC cells due to the oxidative stress caused by ROS. Therefore, an MTT assay was performed to determine the cell viability of HN-3 LSCC cells following treatment with different doses of CBDCA. Subsequently, the expression levels of ROS and the rate of apoptosis/necrosis were evaluated in the cells. Following this, the HN-3 cells were co-treated with CBDCA and glutathione (GSH) or H2O2, followed by an MTT assay, a cell migration assay and western blot analysis. The results demonstrated that CBDCA reduced the viability of HN-3 cells in a time- and dose-dependent manner and promoted the production of ROS and apoptosis at certain doses. Additionally, the combination treatment of CBDCA and H2O2 enhanced the inhibitory effects of CBDCA on cell viability and migration ability, and promoted apoptosis in HN-3 cells; whereas the combined treatment of CBDCA and GSH exerted opposite effects. The results of the present study demonstrated that CBDCA promotes the apoptosis of HN-3 cells through accumulation of ROS, which may provide a novel treatment strategy for treating LSCC.

Abstract
Objective Neck dissection is the most definitive and effective treatment for head and neck cancer. This systematic review aims to compare the efficacy and surgical outcomes of neck dissection between the harmonic scalpel and conventional surgical techniques and conduct a quantitative meta-analysis of the randomized trials. Methods Randomized controlled trials (RCTs) were identified from the major electronic databases (MEDLINE, EMBASE and Cochrane Library) using the keywords ‘‘harmonic scalpel’’ and ‘‘neck dissection,’’ and a quantitative meta-analysis was conducted. The operative time and intraoperative bleeding were the primary outcome measures, and other parameters assessed included the drainage fluid volume and length of hospital stay. Results Seven trials that met the inclusion criteria included 406 neck dissection cases (201 in the harmonic scalpel group). Compared with conventional surgical techniques, the HS group had an operative time that was significantly reduced by 29.3 minutes [mean difference: -29.29; 95% CI = (-44.26, -14.32); P=0.0001], a reduction in intraoperative bleeding by 141.1 milliliters [mean difference: -141.13; 95% CI = (-314.99, 32.73); P=0.11], and a reduction in drainage fluid volume by 64.9 milliliters [mean difference: -64.86; 95% CI = (-110.40, -19.32); P=0.005] , but it is not significant after removal of studies driving heterogeneity. There was no significant difference in the length of the hospital stay [mean difference: -0.21; 95% CI = (-0.48, 0.07); P=0.14]. Conclusion This systematic review showed that using the harmonic scalpel for neck dissection significantly reduces the operative time and drainage fluid volume and that it is not associated with an increased length of hospital stay or perioperative complications. Therefore, the harmonic scalpel method is safe and effective for neck dissection. However, the statistical heterogeneity was high. Further studies are required to substantiate our findings.

Abstract
The cell surface glycoprotein Trop2 is overexpressed in various types of epithelial cancer. Laryngeal carcinoma is one of the most common types of head and neck cancer and in a previous study, the expression of Trop2 in laryngeal squamous cell carcinoma (LSCC) was identified as an independent prognostic factor. However, the biological significance of Trop2 in LSCC development remains unclear. In the current study, Trop2 protein expression in fresh LSCC tissue and paracancerous tissue was investigated using western blotting. Trop2 in the Hep2 laryngeal cell line was subsequently suppressed by transfection with small interfering RNA (siRNA). The effects of knockdown of Trop2 on cell viability, migration, invasiveness and ERK/MAPK pathway activity were investigated in the current study. The expression of Trop2 in fresh LSCC tissue was demonstrated to be significantly greater than that in paracancerous tissue. Trop2 expression was also identified to be required for proliferation, migration and invasiveness of Hep2 laryngeal carcinoma cells, as all were blocked by siRNA-mediated Trop2 inhibition. Notably, the ERK/MAPK signaling pathway and cell cycle factor, cyclin D1, were identified to be suppressed following the knockdown of Trop2 in Hep2 cells. These observations suggest that Trop2 serves an oncogenic role in LSCC and has potential as a therapeutic target.

Abstract
OBJECTIVE The aim of present study was to investigate the expression of SOX2, a key transcription factor, in LSCC and to assess its prognostic significance. METHODS SOX2 expression of 161 LSCC tissues was detected by immunohistochemistry using a tissue microarray and statistically analyzed for its correlation with clinicopathological charateristics and patient outcome. In addition, SOX2 expression was also observed in 20 self-paired fresh LSCC tissues by western blot. RESULTS SOX2 was overexpressed in LSCC tissues as compared to the corresponding adjacent normal tissues. SOX2 expression was significantly associated with tumour T classification (p<0.001), clinical stage (p<0.001), lymph node metastasis (p=0.007) and recurrence (p=0.001). Univariate analysis revealed that patients with high SOX2 expression were significantly related to overall survival (p<0.001). Multivariate survival analysis further demonstrated that SOX2 expression was an independent prognostic factor for LSCC patients. CONCLUSION SOX2 may contribute to the malignant progression of laryngeal squamous cell carcinoma (LSCC), and present as a useful prognostic marker and a potential therapeutic target for LSCC patients.

Med Oncol 2012; 29:2466-72.

Abstract
The laryngeal squamous cell carcinoma (LSCC) is one of the most common cancers threatening people's life. CXC-chemokine receptor type 2 (CXCR2) was reported to play critical roles in angiogenesis, tumorigenesis, and metastasis of several cancers such as colon cancer, melanoma, lung cancer, and so on. However, the expression of CXCR2 in LSCC and its association with clinical characters of LSCC remain unclear. Quantitative real-time reverse transcription-PCR and immunohistochemistry were used, respectively, to analyze the mRNA level and protein level of CXCR2 in 109 cases of LSCC tissues and 28 cases of tumor-adjacent normal tissues. The expression of CXCR2 in LSCC was significantly higher than that in tumor-adjacent tissues. Moreover, the expression level of CXCR2 protein in LSCC was significantly related to lymph node metastasis (P=.022), histopathological grade (P=.038), and 5 years' survival (P=.007). Cox regression analysis revealed that CXCR2 expression (P=.031), as well as lymphatic metastasis (P=.026) and TNM classification (P=.042), is an independent prognostic marker of LSCC. High expression of CXCR2 is also associated with short survival of LSCC patients. Our data indicate that the expression of CXCR2 is associated with the development and progression of LSCC. CXCR2 expression may serve as an independent prognostic marker for LSCC patients.

Abstract
Head and neck cancers are common among men in developing countries. Among head and neck cancers in the United States, supraglottic laryngeal cancer accounts for 12,500 new cases per year. It responds favorably to radiotherapy with or without chemotherapy depending on the stage of disease. Recurrence is local or locoregional. We report a unique case of carcinoma of the larynx with rare distal recurrence in the left inguinal lymph nodes.
