Abstract
PURPOSE OF REVIEW The aim of thi study was to review the recent literature on epidemiology, biology and treatment of laryngeal cancer in paediatric and young adult patients. RECENT FINDINGS Epidemiological studies reported that 2-10% of patients with laryngeal cancer are younger than 40-year-old, while the prevalence of laryngeal cancer remains unknown in the paediatric population. The development of laryngeal cancer in young adults is multifactorial and may be linked to common carcinogens (tobacco and alcohol), occupational factors, laryngopharyngeal reflux, immunosuppression, human papillomavirus infection and genetic polymorphism. A substantial number of cohort studies reported a significant lower proportion of drinkers and smokers in young populations with laryngeal cancer, supporting the higher prevalence of chromosomal losses or abnormalities predisposing to cancer in this group. The development of laryngeal cancer in paediatric patients is strongly associated with genetic syndromes with DNA repair abnormalities. The pathological, clinical and survival outcome differences between young and old patient groups vary significantly between studies, depending on epidemiological, genetic features and therapeutic strategies used. SUMMARY Paediatric and adult populations with laryngeal cancer present different clinical, pathological and survival outcomes. In the adult population, the patient age at the time of disease development underlies genetic and etiological differences with different mutation patterns between young and old patients, the latter being more frequently individuals with a history of tobacco and alcohol abuse. The differences between age groups regarding stage of cancer at initial presentation, as well as clinical and survival outcomes, are unclear, which may be due to demographic, ethnicity and population genetic differences.

Associations of Polymorphisms Localized in the 3'UTR Regions of the KRAS, NRAS, MAPK1 Genes with Laryngeal Squamous Cell Carcinoma. Genes (Basel) 2021; 12:genes12111679. [PMID: 34828284 PMCID: PMC8625477 DOI: 10.3390/genes12111679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 10/18/2021] [Accepted: 10/21/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Genetic variations, localized in the 3′ untranslated region (UTR) in mitogen-activated protein kinase (MAPK) pathway-related genes, may alter the transcription and impact the pathogenesis of laryngeal squamous cell carcinoma (LSCC). The present study investigated the associations of single-nucleotide polymorphisms (SNP), localized in the 3′UTR) of the KRAS, NRAS, and MAPK1 genes with LSCC risk and clinicopathological features. Methods: Genomic DNA and clinical data were collected from 327 adult men with LSCC. The control group was formed from 333 healthy men. Genotyping of the SNPs was performed using TaqMan SNP genotyping assays. Five KRAS, NRAS, and MAPK1 polymorphisms were analyzed. All studied genotypes were in Hardy–Weinberg equilibrium and had the same allele distribution as the 1000 Genomes project Phase 3 dataset for the European population. Results: Significant associations of the studied SNPs with reduced LSCC risk were observed between NRAS rs14804 major genotype CC. Significant associations of the studied SNPs with clinicopathologic variables were also observed between NRAS rs14804 minor T allele and advanced tumor stage and positive lymph node status. SNP of MAPK1 rs9340 was associated with distant metastasis. Moreover, haplotype analysis of two KRAS SNPs rs712 and rs7973450 revealed that TG haplotype was associated with positive lymph node status in LSCC patients. Conclusions: According to the present study, 3′UTR SNP in the NRAS and MAPK1 genes may contribute to the identifications of patients at higher risk of LSCC lymph node and distant metastasis development.

Abstract
BACKGROUND Paediatric squamous cell carcinoma (SCC) of the larynx is rare; however, recent data seem to support the notion that this pathology is increasing in incidence. Although this has been the case for several decades, treatment algorithms for this patient population remain identical to those of adults. METHODS The study consists of a systematic review and pooled analysis of oncologic outcomes in paediatric laryngeal SCC from a comprehensive literature search on OVID MEDLINE and EMBASE. RESULTS The average cohort age was 12.1 years. Nine (36%) had supraglottic primaries, and 16 (64%) had glottic primaries. Treatment included unimodal and combination therapy. No significant difference in survival was noted between surgically treated and non-surgically treated patients (5-year overall survival (OS): 68.2% vs 76.2%, P = .905), even when stratified for advanced-stage and supraglottic disease. CONCLUSIONS Paediatric patients with laryngeal HNSCC may have different presentations and responses to therapy than their adult counterparts.

Abstract
OBJECTIVES To evaluate the prevalence and features of pediatric laryngeal malignancies and to review the demographics, management, and survival of pediatric patients with laryngeal squamous cell carcinoma as compared to adult patients. METHODS Patients aged 0 (younger than 1) to 18 with laryngeal malignancy identified in the Surveillance, Epidemiology, and End Results (SEER) database were included from 1973 to 2016 published April 2019. Diagnosis of malignant laryngeal tumor was made using the 3rd edition of the International Classification of Diseases for Oncology (ICDO-3) code: C32.0 Glottis, C32.1 Supraglottis, C32.2Subglottis, andC32.9 Larynx primary site. RESULTS 23 cases of pediatric laryngeal malignancies were identified. 16 cases were squamous cell carcinomas and 7 were other histologic types. Pediatric laryngeal SCC tended to be diagnosed in adolescence (mean age 14.8 years, range younger than 1 to 18, 82.6% of cases were age 12 and above). Management of laryngeal SCC included no recorded treatment (18.8%), primary radiation (18.8%), primary surgery (12.5%), radiation and surgery (25%), radiation and chemotherapy combined (18.8%), and surgery with radiation and chemotherapy (12.5%). Surgeries were local excision, excision and lymphnode dissection, as well as total laryngectomy, and not otherwise specified. The 2-year and 5-year overall and disease-specific survivals were 78.6%. CONCLUSIONS Pediatric laryngeal cancer is rare. Squamous cell carcinoma is the most commonly diagnosed malignant laryngeal histology affecting pediatric patients. Despite different risk factors, survival rates remain similar for pediatric patients with laryngeal squamous cell carcinoma as compared to adults. Physicians should include laryngeal cancer in the differential for pediatric patients with hoarseness, dysphagia, and progressive airway obstruction to avoid a late diagnosis.

Abstract
Background Cytokines play important roles in the development and prognosis of laryngeal cancer (LC). Interleukin-17 (IL-17) from a distinct subset of CD4+ T cells may significantly induce cancer-elicited inflammation to prevent tumor immune surveillance. Methods The expression levels of IL-17 were examined among 60 patients with LC. Immunofluorescence colocalization experiments were performed to verify the localization of IL-17 and FAS/FASL in Hep-2 and Tu212 cells. The role of IL-17 was determined using siRNA techniques in the LC cell line. Results In the LC patients, cytokines were dysregulated in LC tissues compared with normal tissues. It was found that IL-17 was overexpressed in a cohort of 60 LC tumors paired with nontumor tissues. Moreover, high IL-17 expression was significantly associated with the advanced T category, the late clinical stage, differentiation, lymph node metastasis, and recurrence. In addition, the time course expression of FAS and FASL was observed after stimulation and treatment with the IL-17 stimulator. Finally, in vitro experiments demonstrated that IL-17 functioned as an oncogene by inhibiting the apoptosis of LC cells via the PI3K/AKT/FAS/FASL pathways. Conclusions In summary, these findings demonstrated for the first time the role of IL-17 as a tumor promoter and a prometastatic factor in LC and indicated that IL-17 may have an oncogenic role and serve as a potential prognostic biomarker and therapeutic target in LC.

Abstract
Approximately 7 cases of spontaneous regression of adult laryngeal carcinoma have been published in the literature since 1900. This case presents a 62-year-old male with a 6-month history of hoarseness who was subsequently diagnosed with a T1aN0M0 left true vocal fold squamous cell carcinoma (SCC) after biopsy. One month following the initial biopsy, histopathological findings on repeat biopsy revealed absence of malignancy and regression of the tumor without radiation. There has been no evidence of tumor recurrence. This case exemplifies how innate immune modulation may play a role in the spontaneous regression of laryngeal SCC, although the mechanism remains unknown.

Abstract
Spontaneous tumor regression can be observed in many tumors, however, studies related to the altered expression of lncRNA in spontaneous glioma regression are limited, and the potential contributions of lncRNAs to spontaneous glioma regression remain unknown. To investigate the biological roles of lncRNA-135528 in spontaneous glioma regression. The cDNA fragment of lncRNA-135528 was obtained by rapid-amplification of cDNA ends (RACE) technology and cloned into the plvx-mcmv-zsgreen-puro vector. Additionally, we stably silenced or overexpressed lncRNA-135528 in G422 cells by transfecting with siRNA against lncRNA-135528 or lncRNA-135528 overexpression plasmid. Then, we examined lncRNA-135528 overexpressing and lncRNA-135528 silencing on glioma cells and its effects on CXCL10 and JAK/STAT pathways. The main findings indicated that lncRNA-135528 promoted glioma cell apoptosis, inhibited cell proliferation and arrested cell cycle progression; the up-regulation of lncRNA135528 led to significantly increased CXCL10 levels and the differential expression of mRNA associated with JAK/STAT pathway in glioma cells. lncRNA-135528 can inhibit tumor progression by up-regulating CXCL10 through the JAK/STAT pathway.

Pediatric head and neck squamous cell carcinoma: Patient demographics, treatment trends and outcomes. Int J Pediatr Otorhinolaryngol 2018; 106:21-25. [PMID: 29447885 DOI: 10.1016/j.ijporl.2017.12.032] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Revised: 12/26/2017] [Accepted: 12/29/2017] [Indexed: 11/23/2022]
Abstract
OBJECTIVES To examine patient demographics, temporal and treatment trends, and survival outcomes of pediatric non-nasopharyngeal head and neck squamous cell carcinomas using the National Cancer Database. METHODS The National Cancer Database was queried for pediatric patients (age 0-19 years) diagnosed with squamous cell carcinoma of the head and neck (including oral cavity, oropharynx, nasal cavity, larynx, hypopharynx, and salivary glands) from 2004 to 2013. RESULTS Of 159 patients identified, the majority had oral cavity SCC (55%). There was no discernable change in incidence trends over the study period with the number of cases per year ranging from 10 to 20 (R2 = 0.174). The predominant treatment regimen for the nasal cavity was trimodality (surgery, radiation, and chemotherapy) treatment (29%), chemotherapy and radiation for the oropharynx (40%), and surgery alone for salivary gland (47%), oral cavity (44%), and larynx (22%). The 5-year overall survival for the entire cohort was 74% and by subsite: oral cavity (66%), oropharynx (68%), nasal cavity (75%), and larynx (95%). Laryngeal disease had statistically significant longer survival when compared to oral cavity (p = .031) or oropharynx (p = .029). CONCLUSION Although pediatric non-nasopharyngeal head and neck squamous cell carcinomas are rare, practitioners should be aware of this entity and consider it in the differential diagnosis of pediatric malignancies.
