Long noncoding RNAs (lncRNAs) exert critical roles in the development of various cancers, including human laryngeal cancer. Radioresistance contributes to the predominant causes of laryngeal cancer recurrence after radiotherapy. The aim of our study was to investigate the association of dysregulated lncRNA and radiation resistance in human larynx squamous carcinoma. Here, we investigated the biological roles of lncRNA DiGeorge syndrome critical region gene 5 (DGCR5) in radioresistance of human laryngeal cancer...

OBJECTIVE: Most studies that report on salvage surgery after primary radiotherapy for head and neck squamous cell carcinoma (HNSCC) are small and heterogeneous. Subsequently, some relevant questions remain unanswered. We specifically focused on (1) difference in prognosis per tumor subsite, corrected for disease stage, and (2) differences in prognosis after salvage surgery for local, regional, and locoregional recurrences. STUDY DESIGN: Retrospective analysis. SETTING: Single-center study (2000-2016)...

PURPOSE: The majority of head and neck squamous cell carcinoma (HNSCC) cases in developing countries are associated with cigarette smoking and TP53 mutations. p53 is a transcription factor that activates downstream genes, including the hsa-miR-34a and hsa-miR-34b/c loci, to achieve cell-cycle arrest, senescence, and/or apoptosis. This study examined the differences in expression levels of miR-34 in HNSCC with or without TP53 mutations. METHODS: We examined surgically resected tumor samples and normal adjacent tissues from HNSCC in oral cavity, larynx, and hypopharynx for TP53 mutations (exons 5-8) and miR-34 expression levels...

Head and neck squamous cell carcinomas (HNSCC) preferentially spread to regional cervical tissues and lymph nodes. Here, we hypothesized that lymphotoxin-β (LTβ), receptor LTβR, and NF-κB-inducing kinase (NIK), promote the aberrant activation of alternative NF-κB2/RELB pathway and genes, that enhance migration and invasion of HNSCC. Genomic and expression alterations of the alternative NF-kB pathway were examined in 279 HNSCC tumors from The Cancer Genome Atlas (TCGA) and a panel of HNSCC lines. LTβR is amplified or overexpressed in HNSCC of the larynx or oral cavity, while LTβ, NIK, and RELB are overexpressed in cancers arising within lymphoid oropharyngeal and tonsillar sites...

The model of head and neck squamous cell carcinoma (HNSCC) was used to study the expression of genes encoding actin-binding proteins depending on the type of cell motility. The expression of SNAIL1 and CAPN2 mRNA in HNSCC tissue was higher than in specimens of dysplastic epithelium of the larynx and hypopharynx, which can be explained by activation of mesenchymal and amoeboid types of cell motility. In biopsy material of HNSCC patients with T1-2N0M0, expression of genes responsible for actin-binding proteins differed from that of patients with pretumor pathology of the larynx and hypopharynx: expression of FSCN was lower, while expressions of EZR and CAP1 were higher...

The region of head and neck is critical for respiration, nutrition, and speech. The management of laryngeal tumours can stimulate mutilations and cosmetic deformities and worsen the life. A “non-operative approach” is preferred for patients to whom radiation following surgery, possibly, will direct severe functional destruction predominantly in advanced stage patients having a bulk of carcinoma larynx. The case material for the study was selected from the cross-section of patients registered at the J. K...

Head and Neck cancer is among the most common cancers worldwide, with a high prevalence in south East Asia, Brazil and central Europe. Head and Neck Squamous cell carcinoma (HNSCC) is associated with elevated mutational load but lacks specific genetic mutations. Exposure to carcinogens including tobacco and alcohol are the most dominant etiologic factors of HNSCC, while Epstein-Barr (HBV) and Human Papilloma Viruses (HPV) are associated with nasopharyngeal and oropharyngeal carcinoma, respectively. Surgery including open and minimally invasive procedures is considered the standard of care for the majority of oral cavity and early larynx cancers, while radiation therapy or concurrent chemoradiation are used for the other head and neck cancers...

Purpose: Basaloid squamous cell carcinoma (BSCC) is a rare, high-grade variant of squamous cell carcinoma (SCC). Most published studies based on population-based datasets focus on prognostic differences between SCC and BSCC. Competing risk analyses for this disease have not been performed. We used Surveillance Epidemiology and End Results (SEER) data to calculate and model the cumulative incidence of death for patients with head and neck BSCC (HNBSCC) with competing risk approaches, and built a model to predict probability of cause-specific death for these patients...

Organ preservation protocols utilizing induction chemotherapy as a selection agent have played a critical role in the treatment of advanced laryngeal squamous cell carcinoma (LSCC). The selection of patients who will have a good response to chemoradiation allows for organ preservation in a significant group of patients and minimizes the rate of surgical salvage. While there remains debate regarding its utility when compared to surgery or other organ preservation regimens, the data does suggest an important role for induction chemotherapy in LSCC...
