Abstract
OBJECTIVE To compare the cancer-specific survival (CSS) among patients with locally advanced laryngeal squamous cell carcinoma (LSCC) receiving chemoradiotherapy (CRT) and radiotherapy (RT) treatment, as well as to establish a prognostic nomogram for survival prediction in patients receiving CRT. METHOD Using data from the Surveillance, Epidemiology, and End Results (SEER) database, patients with laryngeal cancer were identified between 2010 and 2015, with follow-up up to 2018. Propensity score matching (PSM) was performed to minimize disproportionate distributions of the potential confounding. Cox regression models were used to evaluate the CSS of two treatment groups. A prognostic nomogram for patients receiving CRT was then developed and evaluated. RESULTS Totally 1085 non-surgical patients with locally advanced LSCC were included in this study (median [IQR] age, 62 [55-69] years; 829 [76.41%] males), of which 913 receiving CRT and 172 receiving RT. After PSM, significantly improved CSS was observed in locally advanced LSCC patients receiving CRT when compared to RT (HR: 0.62 [95% CI 0.42-0.92]; P = 0.014). Then, in the group of 639 locally advanced LSCC patients receiving CRT, a prognostic nomogram based on age, tumor size, N category, and marital status were developed and validated, of which the predictive performance was superior to that of TNM staging system (7th edition). CONCLUSION CSS shows a statistically significant improvement in locally advanced LSCC patients who receipt of CRT when compared with RT. Furthermore, a prognostic nomogram for locally advanced LSCC patients receiving CRT was established, which shows a good calibration and identification accuracy.

Abstract
BACKGROUND We performed a paired analysis to compare the therapeutic effect between the induction chemotherapy-based organ-preservation approach and immediate total laryngectomy in hypopharyngeal squamous cell carcinoma patients requiring total laryngectomy. METHODS 351 patients who were treated with organ-preservation approach were compared with 110 patients who were treated with total laryngectomy. The main measures and outcomes were progression-free survival (PFS), overall survival (OS), and larynx function preservation survival (LFPS). RESULTS No statistical difference was observed for 3-, 5-, and 10-year PFS and OS in two groups. In the organ-preservation group, the 3-, 5-, and 10-year LFPS was 30.7%, 23.3%, and 16.6%, respectively. The LFPS of Stage III > Stage IV, N0 > N1 > N2 > N3, T2 > T3 > T4, CR > PR > SD > PD patients (all p values <0.05). CONCLUSIONS Survival outcomes did not significantly differ between the two groups. The organ-preservation approach allowed more than 70% of the survivors to retain their larynx function.

Abstract
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. Two human larynx squamous carcinoma cell lines (Hep-2 and Hep-2R), with different radiosensitivities in vitro were used in the present study. We observed that DGCR5 was significantly upregulated in Hep-2R cells. Inhibition of DGCR5 by LV-shDGCR5 transfection restrained Hep-2R cell proliferation and sensitized cells to radiation. Reversely, overexpression of DGCR5 exhibited an opposite phenomenon in vitro. In addition, microRNA (miR)-195 was predicted as a direct downstream target of DGCR5. Dual-luciferase reporter and RNA immunoprecipitation assays verified the direct interaction between them. Meanwhile, miR-195 was observed to be reduced in Hep-2R cells and miR-195 mimics repressed Hep-2 cell growth. Moreover, radiosensitivity of Hep-2R cells was greatly enhanced by overexpression of miR-195, which could be reversed by upregulation of DGCR5. Finally, in vivo experiments were used to validate that knockdown of DGCR5 suppressed laryngeal carcinoma via targeting miR-195. In conclusion, we indicated that DGCR5 could contribute to the radioresistance of human laryngeal carcinoma cells via sponging miR-195.

Abstract
Accumulating evidence has suggested that circular RNAs (circRNAs), a novel class of non-coding RNAs, have crucial roles in tumor progression. However, the significance of circRNAs in hypopharyngeal cancer (HCa) remains to be investigated. The present study has identified aberrantly expressed circRNAs by performing circRNA sequencing analyses of three pairs of tumor and adjacent normal samples from patients with HCa. The results demonstrated that 173 circRNAs were differentially expressed (DE), including 71 upregulated and 102 downregulated circRNAs (FDR<0.05 and fold changes of ≥2 or ≤0.5 by Mann-Whitney U test followed by Benjamini-Hochberg correction for multiple testing). Pathway analyses of the genes producing DE circRNAs revealed that many of them were involved in cancer-related pathways. To further illustrate the roles of circRNAs in HCa progression, a competing endogenous RNA (ceRNAs) network was constructed, consisting of circRNAs, miRNA, and miRNA targeted genes. The results demonstrated that multiple cancer-related pathways were affected by performing enrichment analyses of the targeted genes. Of note, a ceRNA subnetwork was isolated, consisting of two circRNAs (hsa_circ_0008287 and hsa_circ_0005027) and one miRNA (hsa-miR-548c-3p), which significantly affect both ErbB and Hippo signaling pathways. In conclusion, the present study identified a set of circRNAs that are potentially implicated in the tumorigenesis of HCa and may serve as potential biomarkers for the diagnosis of HCa.

Abstract
BACKGROUND The primary purpose of this study was to describe variations in incidence rates, resections rates, and types of surgical resection for patients diagnosed with laryngeal and hypopharyngeal cancers in Ontario. METHODS All laryngeal and hypopharyngeal cancer cases in Ontario (2003-2010) were identified from the Ontario Cancer Registry (n = 3034). Variations in incidence rates, resection rates, and type of surgical resection were compared by sex, age group, neighborhood income, community population, health region, and physician specialty. RESULTS Incidence rates per 100 000 vary significantly by sex, age, neighborhood income, and community size. Women, the elderly (75+ years), those in the higher income quintiles, and those living in larger communities were significantly less likely to receive a laryngectomy procedure. CONCLUSIONS Laryngeal and hypopharyngeal cancer incidence rates vary by sex, age, neighborhood income, community size, and health region. Resection rates vary by age, sex, and health region. These disparities warrant further evaluation to improve the quality of delivered care in Ontario.

Abstract
Importance Use of chemoradiotherapy for advanced laryngeal cancer led to a major shift in treatment as an alternative to laryngectomy. Despite widespread adoption of chemoradiotherapy, survival rates have not improved and the original premise of matching neoadjuvant chemotherapy tumor response to determine subsequent treatment has not been followed. Objective To determine whether improved survival could be achieved by incorporating a single cycle of neoadjuvant chemotherapy to select patients with advanced disease for either laryngectomy or concurrent chemoradiotherapy. Design, Setting, and Participants An unselected cohort of 247 patients with laryngeal cancer in an academic institution between 2002 and 2012 was evaluated. Patients with limited disease (stages I and II) underwent endoscopic resection, radiotherapy, or chemoradiotherapy for deeply invasive T2 lesions. For patients with advanced disease (stages III and IV), neoadjuvant chemotherapy, concurrent chemoradiotherapy, or primary surgery was recommended. Overall survival (OS) and disease-specific survival (DSS) were analyzed. Median follow-up was 48 months. The study was conducted from January 1, 2002, to December 31, 2012; data analysis was completed December 1, 2015. Interventions Endoscopic resection, radiotherapy, chemoradiotherapy, neoadjuvant chemotherapy, concurrent chemoradiotherapy, and primary surgery. Main Outcomes and Measures Overall survival and DSS. Results Of the 247 patients, 191 (77.3%) were male; mean (SD) age was 59.6 (10.4) years. Of 94 patients with limited disease, 33 (35.1%) underwent endoscopic resection; 50 (53.2%), radiotherapy alone; and 11 (11.7%), chemoradiotherapy for deeply invasive T2 lesions. Of 153 patients with advanced disease, 71 (46.4%) received neoadjuvant chemotherapy; 50 (32.7%), concurrent chemoradiotherapy; and 32 (20.9%), surgery. Five-year OS and DSS was 75% (95% CI, 68%-81%) and 83% (95% CI, 77%-88%), respectively, for the entire cohort. The DSS was 92% (95% CI, 83%-97%) for patients with stage I or II and 78% (95% CI, 69%-84%) for patients with stage III or IV disease. For patients with advanced disease, 5-year OS and DSS ranged from 78% (95% CI, 55%-90%) and 91% (95% CI, 67%-98%), respectively, for surgery; to 76% (95% CI, 63%-85%) and 79% (95% CI, 67%-88%), respectively, for neoadjuvant bioselection; and to 61% (95% CI, 44%-75%) and 66% (95% CI, 48%-79%), respectively, for primary chemoradiotherapy. Propensity-adjusted, multivariable controlling for known prognostic factors DSS was significantly improved in the neoadjuvant group compared with the chemoradiotherapy group (hazard ratio [HR], 0.48; 95% CI, 0.29-0.80). Conclusions and Relevance Superior survival rates were achieved with a bioselective treatment approach using a single cycle of neoadjuvant chemotherapy. Good survival rates were also achieved in patients selected for primary surgery, and both neoadjuvant chemotherapy and primary surgery were better than survival rates with concurrent chemoradiotherapy, suggesting that the optimal individualized treatment approach for patients with advanced laryngeal cancer has not yet been defined.

Abstract
Chemoradiotherapy is the treatment mostly used as organ preservation (OP) strategy worldwide in advanced laryngo-hypopharyngeal cancer. Due to the not homogeneous results of the literature data regarding the pre-treatment assessment and treatment schedule in this setting of patients, the Italian societies of radiation oncology and medical oncology surveyed (by an online survey) their memberships regarding the Italian attitude on larynx preservation in clinical practice. The survey outline addressed different items such as: demographics (11 items), pre-treatment evaluation (12 items), treatment schedules (10 items) and outcomes (3 items). The survey was filled in by 116 clinical oncologists (64 % radiation and 36 % medical oncologists). Results highlighted that pretreatment evaluation was not homogeneous among the respondents. The treatment of choice for the OP program resulted the concurrent chemoradiotherapy (66 %). Induction chemotherapy was proposed mostly in case of aggressive tumors such as advanced stage (T4 or N3) and/or unfavorable primary sites (hypopharynx). Moreover, after induction chemotherapy, for responders patients most participants (46 %) proposed concurrent chemoradiotherapy, while 18 and 19 % proposed radiotherapy alone or radiotherapy and cetuximab, respectively. For patients with stable disease after induction chemotherapy, the respondents declared to suggest surgery, radiotherapy and cetuximab or radiotherapy alone in 38, 32 and 15 % of cases, respectively. Results of the present survey highlighted the variability of therapeutic approaches offered in clinical practice for patients candidate to a larynx OP program. Analysis of abovementioned results may give the chance to modify some clinical attitudes and create the background for future clinical investigation in this field.
