Abstract
BACKGROUND Laryngeal cancer has a significant impact on speech, swallowing, and quality of life. This study aims to analyze laryngeal cancer trends using the National Inpatient Sample (NIS) database, providing insights into its epidemiology. METHODS Data from the NIS database was analyzed for a cohort of 14,282 laryngeal cancer cases from 2016 to 2019. Baseline characteristics and demographic parameters, including primary expected payer, age groups, hospital types, and geographic regions, were examined. Descriptive statistics and trend analysis were conducted. RESULTS The cohort showed consistent annual case numbers (range: 3739-3948). The highest case numbers were in the 40-64 age group (average 1998 cases/year), followed by the 65-80 age group (average 1473 cases/year). Medicare was the most common primary expected payer, followed by Medicaid, private insurance, self-pay, and no charge. The cohort was roughly three times more skewed toward males, with an average of 2936 male cases per year compared to 885 female cases. Notable trends included significant positive correlations with time for urban teaching hospitals, the South region, older age group (65-80 years), and Asian or Pacific Islander individuals. However, the overall correlation between case numbers and time was not statistically significant. The primary expected payer and deaths exhibited moderate correlations with time but did not reach statistical significance. CONCLUSION This study provides insights into the baseline characteristics and trends in laryngeal cancer incidence. The observed demographic shifts highlight the need for further investigation into underlying factors influencing case distribution. Understanding these trends can guide targeted interventions for prevention, early detection, and treatment of laryngeal cancer.

Updated disease distributions, risk factors, and trends of laryngeal cancer: a global analysis of cancer registries. Int J Surg 2024; 110:810-819. [PMID: 38000050 PMCID: PMC10871644 DOI: 10.1097/js9.0000000000000902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 11/03/2023] [Indexed: 11/26/2023]
Abstract
BACKGROUND Though the laryngeal cancer only has 1% of the total cancer cases and related deaths, it is a type of head and neck cancers with the highest prevalence. This study aims to investigate the epidemiological trend of laryngeal cancer with updated data on the global distribution of the disease burden. MATERIALS AND METHODS The incidence and mortality rate of laryngeal cancer was extracted from GLOBOCAN (2020), Cancer Incidence in Five Continents series I-X, WHO mortality database , the Nordic Cancer Registries , and the Surveillance, Epidemiology, and End Results Program. The Global Health data exchanges for the prevalence of its associated risk factors. A Joinpoint regression analysis was used to calculate Average Annual Percentage Change (AAPC). RESULTS The age-standardised rate (ASR) of laryngeal cancer incidence and mortality were 2.0 and 1.0 per 100 000 worldwide. The Caribbean (ASR=4.0) and Central and Eastern Europe (ASR=3.6) had the highest incidence and mortality rate. Incidence and risk factors associated with laryngeal cancer included tobacco usage, alcohol consumption, poor diet, obesity, diabetes, hypertension, and lipid disorders. There was an overall decreasing trend in incidence, especially for males, but an increasing incidence was observed in female populations and younger subjects. CONCLUSIONS As overall global trends of laryngeal cancer have been decreasing, especially for the male population, this could possibly be attributed to reduced tobacco use and alcohol consumption. Decrease in mortality may be due to improved diagnostic methods and accessibility to treatment, yet disparity in trend remains potentially because of differences in the level of access to surgical care. Disparities in temporal trends across countries may require further research and exploration to determine other underlying factors influencing this.

Abstract
BACKGROUND Intercellular adhesion molecule-1 (ICAM-1) is a surface glycoprotein important for tumor invasion and angiogenesis. The present research is conducted to investigate whether specific gene polymorphism of ICAM-1 K469E (rs5498) and plasma redox status could be associated with laryngeal cancer (LC) development. Since there is no clear evidence which investigates the relationship between ICAM-1 polymorphism and ROS-mediated plasma protein oxidation in LC, our study is the first significant contribution for investigating the relationship. METHODS The study covered patients with primary LC and their age-matched healthy control subjects. Evaluation of ICAM-1 K469E (rs5498) gene polymorphism was performed by polymerase chain reaction-restriction fragment length polymorphism. Plasma redox status was assessed with spectrophotometric methods. RESULTS In the current paper, we found that LC patients with GG genotype had a decreasing trend for the plasma oxidative damage biomarker levels when compared with all allele genotypes (AA and AG). CONCLUSION We concluded that G allele of the ICAM-1 K469E gene plays a significant role in the optimal regulation of plasma redox homeostasis in patients with LC.

Abstract
Recurrent laryngeal carcinoma presents differences from the primary tumor that largely depend on the treatment. In this article, we review the histologic and molecular treatment-induced changes that may affect the diagnosis of recurrent laryngeal carcinoma, the assessment of predictive markers, and the response to treatment with immune checkpoint inhibitors. Radiotherapy induces profound modifications that are strictly related to necrosis of different tissue components, fibrosis, and damage of the tumor vessels. Postradiotherapy recurrent/persistent laryngeal squamous cell carcinoma typically presents a discohesive growth pattern within a fibrotic background associated with significant changes of the tumor immune microenvironment, with both important immunosuppressive and immunostimulatory effects. Overall, the increase of immunoregulatory cells and immune checkpoints such as CTLA-4, TIM-3, PD-1, and PD-L1 induced by radiotherapy and chemotherapy strongly supports the use of immune checkpoint inhibitors in recurrent/persistent laryngeal carcinoma. Future studies aiming to identify predictive factors of the response to immune checkpoint inhibitors should consider such treatment-induced modifications.

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.

Zafeiris KN. Greece since the 1960s: the mortality transition revisited: a joinpoint regression analysis. JOURNAL OF POPULATION RESEARCH 2023; 40:3.

Abstract
Mortality transition in Greece is a well-studied phenomenon in several of its aspects. It is characterised by an almost constant increase in life expectancy at birth and other ages and a parallel decrease in death probabilities. The scope of this paper is a comprehensive assessment of the mortality transition in Greece since 1961, in the light of holistic analysis. Within this paper, life tables by gender were calculated and the temporal trends of life expectancy at several ages were examined. Moreover, a cluster analysis was used in order to verify the temporal changes in the mortality patterns. The probabilities of death in large age classes are presented. Furthermore, the death distribution was analysed in relation to various parameters: the modal age at death, mode, left and right inflexion points and the length of the old age heap. Before that, a non-linear regression method, originating from the stochastic analysis, was applied. Additionally, the Gini coefficient, average inter-individual differences, and interquartile range of survival curves were examined. Finally, the standardised rates of the major causes of death are presented. All the analysis variables were scholastically examined for their temporal trends with the method of Joinpoint Regression analysis. Mortality transition in Greece after the year 1961 is asymmetrical with a gender and an age-specific component, leading to the elevation of life expectancy at birth over time. During this period, the older ages' mortality decreases, but at a slower pace than that of the younger ones. The modal age at death, mode, the left and right inflexion points and the width of the old age heap denote the compression of mortality in the country. The old age death heap shifts towards older ages, while at the same time, the variability of ages at death decreases, being verified by the Gini Coefficient and average inter-individual differences. As a result, the rectangularization of survival curves is evident. These changes have a different pace of transition over time, especially after the emergence of the economic crisis. Finally, the major causes of death were the diseases of the circulatory system, neoplasms, diseases of the respiratory system and others. The temporal trends of these diseases differ according to the diseases and gender. Greece's mortality transition is an asymmetrical stepwise process characterised by its gender and age-specific characteristics. This process, despite being a continuous one, is not linear. Instead, a combination of serious developments over time governs the country's modern mortality regime. The evaluation of Greece's mortality transition through the lens of more advanced analytical methods may provide new insights and methodological alternatives for assessing mortality transition in other countries of the world.

Abstract
BACKGROUND Pharynx and larynx cancers (PLCs) are the top killer cancers in head and neck and significantly affect the quality of life of patients. A detailed study examining the disease burden and risk factors of PLCs is lacking. METHODS Data on mortality and disability-adjusted life-years (DALYs) were extracted from the Global Burden of Disease Study 2019. The estimated annual percentage change (EAPC) of the age-standardized mortality rate was calculated using a generalized linear model with a Gaussian distribution. Mortality and DALYs were stratified according to the sociodemographic index (SDI), age, gender, and risk factors. The association between the SDI and mortality rate was measured using Spearman's correlation. RESULTS Between 1990 and 2019, the total number of deaths due to PLCs increased by 60.7% (95% confidence intervals: 39.32 to 66.8), from 192.38 thousand in 1990 to 309.16 thousand in 2019, and the total DALYs due to PLCs increased by 49.41% (95% confidence intervals: 30.15 to 53.27), from 5.91 million in 1990 to 8.83 million in 2019. The age-standardized mortality rate declined for larynx cancer (from 2.19 in 1990 to 1.49 in 2019) and nasopharynx cancer (1.26 to 0.86) but increased slightly for other pharynx cancer (1.25 to 1.37). The death number of PLCs was significantly higher in men aged 50 to 70 years, which accounts for 46.05% and 43.83% of the total deaths in 1990 and 2019, respectively. Low and low-middle countries had the greatest age-standardized mortality rate for larynx and other pharynx cancer, while low-middle and middle countries dominated for nasopharynx cancer. The leading risk factors for PLCs were smoking and alcohol use, which account for 37.92% and 58.84% in total DALYs rate of PLCs, and the influence of risk factors was significant in men. CONCLUSION The total number of deaths and DALYs due to PLCs increased from 1990 to 2019. Countries with relatively low SDI and middle-aged and older men had the greatest burden of PLCs. Building better health care systems in relatively low SDI countries and improving strategies of smoking and alcohol control should be a priority in health policy.

Abstract
Total laryngectomy, i.e., the surgical removal of the larynx, has a profound influence on a patient's quality of life. The procedure results in a loss of natural voice, which in effect constitutes a significant socio-psychological problem for the patient. The main aim of the study was to develop a statistical parametric speech synthesis system for a patient with laryngeal cancer, on the basis of the patient's speech samples recorded shortly before the surgery and to check if it was possible to generate speech quality close to that of the original recordings. The recording made use of a representative corpus of the Polish language, consisting of 2150 sentences. The recorded voice proved to indicate dysphonia, which was confirmed by the auditory-perceptual RBH scale (roughness, breathiness, hoarseness) and by acoustical analysis using AVQI (The Acoustic Voice Quality Index). The speech synthesis model was trained using the Merlin repository. Twenty-five experts participated in the MUSHRA listening tests, rating the synthetic voice at 69.4 in terms of the professional voice-over talent recording, on a 0-100 scale, which is a very good result. The authors compared the quality of the synthetic voice to another model of synthetic speech trained with the same corpus, but where a voice-over talent provided the recorded speech samples. The same experts rated the voice at 63.63, which means the patient's synthetic voice with laryngeal cancer obtained a higher score than that of the talent-voice recordings. As such, the method enabled for the creation of a statistical parametric speech synthesizer for patients awaiting total laryngectomy. As a result, the solution would improve the quality of life as well as better mental wellbeing of the patient.

Abstract
INTRODUCTION: Larynx cancer is one of the most common head and neck cancers, whose main risk factors are smoking and alcohol use, and its occurrence and prognosis depend on adequate and timely preventive measures. This study aimed to investigate the burden of larynx cancer in Brazil and its states. METHODS: Using estimates from the Global Burden of Disease Study 2019, this study analyzed the trends of incidence, mortality, and disability-adjusted life years (DALYs) for larynx cancer between 1990 and 2019, besides the mortality-to-incidence ratio and the socio demographic index. RESULTS: Incidence and mortality due to larynx cancer in Brazil, which are approximately eight-fold higher for men, showed a declining trend between 1990 and 2019 (APPC: -0.4% and -1.0%, respectively). The DALYs also showed negative variation between 1990 and 2019 for both sexes in Brazil, mainly due to the decrease in premature deaths, with the greatest reduction in the state of São Paulo. For the states of Brazil in 2019, the higher age-standardized incidence rate (Rio Grande do Sul, 3.83 cases per 100,000 inhabitants) is twice the lowest rate (Piauí, 1.56 cases per 100,000 inhabitants). CONCLUSIONS: A fall in the burden of larynx cancer was observed in Brazil over the past 30 years, which may be attributed to a reduction in smoking and to an improvement in treatment. However, the regional inequalities in the country remain evident, especially for males. This data can guide public policy priorities to control the disease in Brazil.

Kuzmickiene I, Everatt R. Trends and age-period-cohort analysis of upper aerodigestive tract and stomach cancer mortality in Lithuania, 1987-2016. Public Health 2021; 196:62-68. [PMID: 34153634 DOI: 10.1016/j.puhe.2021.05.001] [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: 09/15/2020] [Revised: 04/08/2021] [Accepted: 05/03/2021] [Indexed: 01/04/2023]
Abstract
OBJECTIVES Lithuania has among the highest mortality rates for upper aerodigestive tract (UADT) and stomach cancer in Europe. The aim of this study was to analyze trends during the period 1987-2016 in Lithuania, evaluating the effect of birth-cohort, period, and age. STUDY DESIGN Observational time trends study. METHODS Data on numbers of deaths and population size by each calendar year in 5-year age groups in 1987-2016 were obtained from the WHO mortality database. Joinpoint regression analysis was used to evaluate changes in time trends. Age-period-cohort analysis was performed to assess age, calendar period of death, and birth-cohort effects. RESULTS UADT cancer mortality in men increased between 1987 and 1993, annual percentage change (APC) = 6.6% (95% confidence interval [CI]: 3.8, 9.4), and was stable thereafter, APC = 0.3% (95% CI: 0.0, 0.6). The age-standardized mortality rate (ASMR) was 23.6/100,000 in 2016. In women, rates increased steadily by 1.6% (95% CI: 0.9%, 2.3%) per year from 1987 to 2016, ASMR = 2.3/100,000 in 2016. Age-period-cohort analysis showed statistically significant cohort effects in both sexes. In men, rates peaked in birth-cohorts born around 1952, declined in 1957-1962 birth-cohorts, and fluctuated in later birth-cohorts. In women, rates started rising in 1947 birth cohort and peaked in the 1967 birth cohort. Stomach cancer mortality declined throughout the study period in men by -2.4%, (95% CI: -2.6%, -2.1%) annually, and women by -2.8% (95% CI: -3.1%, -2.4%), ASMR = 16.1/100,000 and 6.0/100,000 in 2016, respectively. Birth-cohort effects were significant in both sexes. Rates decreased in cohorts born around 1920 onwards, but declines in the youngest generations have slowed in men and reversed in women. CONCLUSIONS The birth-cohort effects in UADT and stomach cancer mortality trends imply that the elevated burden in Lithuania could be reduced by effective strategies targeting known risk factors. Further research in causes of unfavorable trends in younger cohorts is warranted.

Abstract
Introduction Although in Poland at the turn of the 20th and 21st centuries, tobacco consumption per capita was one of the highest in the world as a result of specific political and social conditions, nicotinism was the most common preventable cause of death that reduced life expectancy by 10 years on average. The aim of this study is to determine the level of premature mortality and its trends by age and sex for tobacco-related malignancies in Poland in the years 2008–2017. Methods The standardised premature mortality rates as well as mortality rates for five-year age ranges according to the patients’ sex were used. The Joinpoint model was used to determine the time trends. Results Premature mortality due to all tobacco-dependent cancers analysed decreased in Poland throughout the analysed period in both male (2.5% per year) and female (1% per year) populations. A detailed analysis of individual diseases showed that a decrease in premature mortality was observed for almost all malignancies with the exception of malignant liver cancer among males, malignant oesophageal cancer among females and malignant lip, oral cavity and oropharyngeal cancer in both sexes. The reduction in mortality from all tobacco-related cancers in the male population was greatest between 40 and 44 years of age, reaching 5.6% year on year. Similarly, in the case of females, the decline in mortality was greater in the younger age cohorts and decreased in those aged over 50. Conclusion The favourable phenomenon of decreasing the level of premature mortality caused by tobacco-related malignancies may be associated, among others, with the policy of primary prevention of these diseases in the form of a widespread ban on smoking in public places, intensive information campaigns on the harmfulness of tobacco smoking and increasing taxation on tobacco products.

A roadmap of six different pathways to improve survival in laryngeal cancer patients. Curr Opin Otolaryngol Head Neck Surg 2021; 29:65-78. [PMID: 33337612 DOI: 10.1097/moo.0000000000000684] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/24/2022]
Abstract
PURPOSE OF REVIEW Laryngeal cancer continues to require improvement in earlier stage diagnosis and better imaging delineation of disease, and hence 'more evidence-based' selection of treatment, as recent evidence suggests that related mortality, in the last decades, has not significantly decreased worldwide. Even though the reasons are not fully understood, there persists an urgency for a review and development of future strategies to embrace such clinical and diagnostic challenges from a political, societal, as well as scientific and clinical points of view. RECENT FINDINGS This review of the published literature suggests that survival improvement in laryngeal cancer may be achieved by fuelling and combining at least some or all of six targeted agendas: documentation of disease global incidence and national burden monitoring; development and implementation of high-quality cancer registries; education on risk factors and hazardous habits associated with laryngeal cancer for the general population; active modification of proven at-risk population lifestyles; centralization of treatment; and use of machine learning of gathered 'big data' and their integration into approaches for the optimization of prevention and treatments strategies. SUMMARY Laryngeal cancer should be tackled on several fronts, commencing with disease monitoring and prevention, up to treatment optimisation. Available modern resources offer the possibility to generate significant advances in laryngeal cancer management. However, each nation needs to develop a comprehensive approach, which is an essential prerequisite to obtain meaningful improvement on results.

T1a Glottic Cancer: Advances in Vocal Outcome Assessment after Transoral CO 2-Laser Microsurgery Using the VEM. J Clin Med 2021; 10:jcm10061250. [PMID: 33802971 PMCID: PMC8002749 DOI: 10.3390/jcm10061250] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 03/10/2021] [Accepted: 03/15/2021] [Indexed: 12/18/2022] Open
Abstract
Patients with unilateral vocal fold cancer (T1a) have a favorable prognosis. In addition to the oncological results of CO2 transoral laser microsurgery (TOLMS), voice function is among the outcome measures. Previous early glottic cancer studies have reported voice function in patients grouped into combined T stages (Tis, T1, T2) and merged cordectomy types (lesser- vs. larger-extent cordectomies). Some authors have questioned the value of objective vocal parameters. Therefore, the purpose of this exploratory prospective study was to investigate TOLMS-associated oncological and vocal outcomes in 60 T1a patients, applying the ELS protocols for cordectomy classification and voice assessment. Pre- and postoperative voice function analysis included: Vocal Extent Measure (VEM), Dysphonia Severity Index (DSI), auditory-perceptual assessment (GRB), and 9-item Voice Handicap Index (VHI-9i). Altogether, 51 subjects (43 male, eight female, mean age 65 years) completed the study. The 5-year recurrence-free, overall, and disease-specific survival rates (Kaplan–Meier method) were 71.4%, 94.4%, and 100.0%. Voice function was preserved; the objective parameter VEM (64 ± 33 vs. 83 ± 31; mean ± SD) and subjective vocal measures (G: 1.9 ± 0.7 vs. 1.3 ± 0.7; VHI-9i: 18 ± 8 vs. 9 ± 9) even improved significantly (p < 0.001). The VEM best reflected self-perceived voice impairment. It represents a sensitive measure of voice function for quantification of vocal performance.

Abstract
INTRODUCTION Recurrent early glottic cancer (rEGC) poses several issues in terms of timely diagnosis, correct re-staging, and treatment. We want to critically review the latest evidence about rEGC considering its epidemiology, biology, diagnostic challenges, and treatment strategies. METHODS A systematic search of the literature using PubMed from 1990 to October 31, 2020 was performed. RESULTS There are many different treatment options available (open surgery, transoral mini-invasive surgery, radiotherapy), and many factors related to the patient's status and previous treatments must be considered when planning the best management strategy for rEGC. While its overall prognosis remains satisfactory, it is of the utmost importance to appreciate all the clinical implications derived from the choice of the initial therapeutic modality, and from a correct primary and recurrent staging. CONCLUSION The balance between oncological and voice and swallowing functions represents the fundamental principle underlying rEGC management. Future studies should focus on molecular profiling of rEGC, and on the results of the emerging radiation delivery techniques and mini-invasive procedures.

Abstract
OBJECTIVE The aim of this study was to investigate the diagnostic accuracy of staging 18F-FDG-PET/CT in laryngeal cancer, compare these results with conventional imaging (CI) and assess the value of 18F-FDG-PET/CT features to predict survival. METHODS Fifty-four patients with laryngeal squamous cell cancer and baseline 18F-FDG-PET/CT were retrospectively enrolled. The PET images were analyzed visually and semi-quantitatively by measuring several metabolic parameters. A combination of clinical follow-up/imaging follow-up and/or histopathology was taken as reference standard. Progression free survival (PFS) and disease specific survival (DSS) were computed using Kaplan-Meier curves. RESULTS All primary tumors were clearly identified by CI, and 52/54 by 18F-FDG-PET/CT with a sensitivity of 96.3%. Cervical nodal metastases were detected in 40/54 patients at 18F-FDG-PET/CT and in 34/49 patients at CI. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy on a patient-based analysis for nodal disease were 100%, 85.7%, 94.6%, 100% and 95.9% at 18F-FDG-PET/CT, and 91.4%, 85.7%, 94.1%, 80%, 89.8% at CI. Diagnostic performances of PET/CT and CI were not significantly different on a patient-based, side-by-side and level-by-level analysis. 18F-FDG-PET/CT recognized distant metastases in 7 patients allowing to an upstaging. At a median follow-up of 27 months, relapse/progression of disease occurred in 31 patients and death occurred in 32. Metabolic tumor volume (MTV T), MTV total and total lesion glycolysis (TLG) showed to be independent prognostic factors for PFS. CONCLUSIONS Both CI and PET/CT had good diagnostic performances for the staging of laryngeal cancer; baseline metabolic features (MTV and TLG) showed an important prognostic value in assessing the rate of PFS.

Abstract
CLINICAL/METHODICAL ISSUE Laryngeal cancer is the third most common malignancy in the head and neck region. Endoscopic laryngoscopy with assessment of vocal fold function, microlaryngoscopy with biopsy and computed tomography (CT)/magnetic resonance imaging (MRI) remain the cornerstones of diagnostic workup. Thus, in the context of therapy planning, consideration of individual functional and socioeconomic aspects is of major importance. STANDARD RADIOLOGICAL METHODS Due to the short acquisition time and the possibility to perform functional maneuvers, CT is the tool of choice. MRI allows better soft tissue differentiation, but is more susceptible to movement artifacts and is complicated by disease-specific symptoms. The choice of examination method therefore depends on the patient's physical resilience. PERFORMANCE Depending on the study, the information on the sensitivity of CT with regard to the question of cartilage infiltration varies between 62 and 87% with a specificity between 75 and 98%. For MRI, sensitivity between 64 and 95% and specificity between 56 and 88% are stated. ACHIEVEMENTS The synthesis of the findings from endoscopy, biopsy and imaging is prerequisite for initiation of stage-appropriate treatment. For image interpretation, knowledge of the anatomical landmarks is essential. However, the assessment of posttherapeutic changes also poses a challenge for the radiologist. PRACTICAL RECOMMENDATIONS Regular interdisciplinary dialogue between radiologists, otorhinolaryngologists and radiotherapists in the context of primary diagnostics, therapy planning and aftercare is essential.

Abstract
Voice changes may be the earliest signs in laryngeal cancer. We investigated whether automated voice signal analysis can be used to distinguish patients with laryngeal cancer from healthy subjects. We extracted features using the software package for speech analysis in phonetics (PRAAT) and calculated the Mel-frequency cepstral coefficients (MFCCs) from voice samples of a vowel sound of /a:/. The proposed method was tested with six algorithms: support vector machine (SVM), extreme gradient boosting (XGBoost), light gradient boosted machine (LGBM), artificial neural network (ANN), one-dimensional convolutional neural network (1D-CNN) and two-dimensional convolutional neural network (2D-CNN). Their performances were evaluated in terms of accuracy, sensitivity, and specificity. The result was compared with human performance. A total of four volunteers, two of whom were trained laryngologists, rated the same files. The 1D-CNN showed the highest accuracy of 85% and sensitivity and sensitivity and specificity levels of 78% and 93%. The two laryngologists achieved accuracy of 69.9% but sensitivity levels of 44%. Automated analysis of voice signals could differentiate subjects with laryngeal cancer from those of healthy subjects with higher diagnostic properties than those performed by the four volunteers.

Abstract
OBJECTIVES To outline which infectious diseases in the pre-covid-19 era persist in children and adolescents in China and to describe recent trends and variations by age, sex, season, and province. DESIGN National surveillance studies, 2008-17. SETTING 31 provinces in mainland China. PARTICIPANTS 4 959 790 Chinese students aged 6 to 22 years with a diagnosis of any of 44 notifiable infectious diseases. The diseases were categorised into seven groups: quarantinable; vaccine preventable; gastrointestinal and enteroviral; vectorborne; zoonotic; bacterial; and sexually transmitted and bloodborne. MAIN OUTCOME MEASURES Diagnosis of, and deaths from, 44 notifiable infectious diseases. RESULTS From 2008 to 2017, 44 notifiable infectious diseases were diagnosed in 4 959 790 participants (3 045 905 males, 1 913 885 females) and there were 2532 deaths (1663 males, 869 females). The leading causes of death among infectious diseases shifted from rabies and tuberculosis to HIV/AIDS, particularly in males. Mortality from infectious diseases decreased steadily from 0.21 per 100 000 population in 2008 to 0.07 per 100 000 in 2017. Quarantinable conditions with high mortality have effectively disappeared. The incidence of notifiable infectious diseases in children and adolescents decreased from 280 per 100 000 in 2008 to 162 per 100 000 in 2015, but rose again to 242 per 100 000 in 2017, largely related to mumps and seasonal influenza. Excluding mumps and influenza, the incidence of vaccine preventable diseases fell from 96 per 100 000 in 2008 to 7 per 100 000 in 2017. The incidence of gastrointestinal and enterovirus diseases remained constant, but typhoid, paratyphoid, and dysentery continued to decline. Vectorborne diseases all declined, with a particularly noticeable reduction in malaria. Zoonotic infections remained at low incidence, but there were still unpredictable outbreaks, such as pandemic A/H1N1 2009 influenza. Tuberculosis remained the most common bacterial infection, although cases of scarlet fever doubled between 2008 and 2017. Sexually transmitted diseases and bloodborne infections increased significantly, particularly from 2011 to 2017, among which HIV/AIDS increased fivefold, particularly in males. Difference was noticeable between regions, with children and adolescents in western China continuing to carry a disproportionate burden from infectious diseases. CONCLUSIONS China's success in infectious disease control in the pre-covid-19 era was notable, with deaths due to infectious diseases in children and adolescents aged 6-22 years becoming rare. Many challenges remain around reducing regional inequalities, scaling-up of vaccination, prevention of further escalation of HIV/AIDS, renewed efforts for persisting diseases, and undertaking early and effective response to highly transmissible seasonal and unpredictable diseases such as that caused by the novel SARS-CoV-2 virus.

Abstract
Objective Laryngeal cancer is an important oncologic entity, whose prognosis depends on establishing appropriate preventive and diagnostic measures, especially in populations at higher risk. Methods Epidemiologic information including worldwide incidence, prevalence, burden of health loss (disability-adjusted life year; DALYs) and mortality of larynx cancer was obtained from the Global Health Data Exchange (GHDx) database. Results The current incidence, prevalence and mortality of laryngeal cancer are estimated at 2.76 cases/year per 100,000 inhabitants, 14.33 cases/year per 100,000 inhabitants and 1.66 deaths/year per 100,000 inhabitants, respectively, averaging 3.28 million DALYs each year. Incidence and prevalence have increased by 12% and 24%, respectively during the past 3 decades, whilst mortality has declined by around 5%. The epidemiologic burden of this malignancy is approximately 5-fold higher in males and increases in parallel with ageing, peaking after 65 years of age. Both incidence and mortality rates are higher in Europe and lower in Africa, but the ratio between deaths and incidence is the highest in Africa. Incidence has gradually declined in Europe during the past 3 decades, whilst it has increased in South-East Asia and Western Pacific. Cigarette smoking and alcohol abuse contribute for about 90% of overall worldwide mortality for laryngeal cancer. Conclusions Laryngeal cancer still poses a high clinical and societal burden, with an escalating temporal trend not expected to reverse soon.

Abstract
The consequence of total laryngectomy is complete loss or disorder of smell. The change may affect daily life and decrease the standard of living of people after larynx removal. A study was carried out in a group of 19 people in order to demonstrate whether applying nasal airflow-inducing maneuvers improves smell. The research was conducted during rehabilitation by the seaside in 2018. The group included 6 women and 13 men. There were two tests. The first was done before presentation of nasal airflow-inducing maneuvers. The group received 10 fragrances and were asked to identify them. Next nasal airflow-inducing maneuvers were presented and a training session was carried out. The second test was performed. According to the analysis of results, in most participants their odor sensation improved, but to different levels. Smell exercise in necessary in rehabilitation of patients after larynx removal. A person who can conduct olfactory therapy can be a speech therapist.

Abstract
OBJECTIVE To study the expression of three genes IL-21, FBXL20 and tumour suppressor gene PTEN in laryngeal cancer; analyse the differences in their expression in laryngeal cancer and adjacent tissues; by using pEGFP-N1-IL21 and pGPU/GFP/Neo-FBXL20 expression vectors, to analyse the characteristics in their expression in laryngeal cancer cells outside the body as well as the associations among them. METHODS The expression of the three genes in laryngeal cancer and adjacent tissues from 30 cases and in normal laryngeal tissues from 20 healthy persons was detected with the RT-PCR; laryngeal cancer cell line (HEp-2 cells) transfection was also performed with the pEGFP-N1-IL21 and pGPU/GFP/Neo-FBXL20 expression vectors we constructed, to detect the mRNA expression of the three genes. Cell proliferation, apoptosis and cell cycle were measured by the MTT assay. RESULTS The results of RT-PCR showed that the expression of IL-21 and FBXL20 was up-regulated in laryngeal cancer, while the expression of tumour suppressor gene PTEN was significantly decreased (p < 0.01). In HEp-2 cells transfected with pGPU/GFP/Neo-IL-21 and pGPU/GFP/Neo-FBXL20 expression vectors, the mRNA expression of PTEN was restored to some extent (p < 0.05); in addition, the ability of HEp-2 cells in proliferation and invasion was also reduced. CONCLUSIONS IL-21 and FBXL20 genes are important in the occurrence and development of laryngeal cancer; the expression of PTEN gene can suppress laryngeal cancer, and there's a certain association among IL-21, FBXL20 and PTEN.

Abstract
OBJECTIVE Autophagy is a cellular pathway that regulates the transportation and degradation of cytoplasmic macromolecules and organelles towards lysosome, which is often related to the tumorigenesis and tumor suppression. Here, we investigate the regulating effect of PTEN gene on autophagy-related protein P62 in rat colorectal cancer (CRC) cells and explore the application value of PTEN gene in clinic. METHODS Rat colorectal cancer was induced by intraperitoneal injection of 1,2-dimethyl hydrazine in male ACI rats. A total of 20 rats were randomly selected from those successfully induced with CRC as the experimental group, while 10 healthy rats as control. The rat CRC cells were isolated and cultured. After transfecting the rat CRC cells with pEGFP-N1-PTEN plasmid, RT-PCR was adopted to examine that gene expression of p62 and PTEN, while Western blotting was used to detect the protein expression of p62 and PTEN. Also, the proliferation of CRC cells was measured by MTT assay. RESULTS The expression of PTEN gene in the experimental group was significantly inhibited as compared with the control group, while the expression of P62 gene was significantly increased (p < 0.05). Western blotting demonstrated that the PTEN protein in the experimental group was lower, while the expression of P62 protein was higher. When the CRC cells were transfected with pEGFP-N1-PTEN plasmid, the PTEN expressions were elevated, while p62 was down-regulated. Also, the proliferation of CRC cells was inhibited. CONCLUSION The expression of PTEN gene is negatively correlated with the expression of P62 gene in rat CRC cells. And the expression of PTEN gene can inhibit the occurrence and development of colorectal cancer, thus providing theoretical basis for future clinical treatment.

Eur Arch Otorhinolaryngol 2018; 276:459-466. [PMID: 30569190 PMCID: PMC6394425 DOI: 10.1007/s00405-018-5256-1] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Accepted: 12/14/2018] [Indexed: 12/15/2022]
Abstract
Purpose Flexible transnasal endoscopy is a common examination technique for the evaluation of laryngeal lesions, while the use of narrow band imaging (NBI) has been reported to enhance the diagnostic value of white light endoscopy (WLE). The purpose of this study is to assess observer variability and diagnostic value of both modalities and investigate the possible influence of previous laryngeal surgery on the detection rates of laryngeal malignancy. Methods The study was based on the retrospective evaluation of 170 WLE and NBI images of laryngeal lesions by three observers in a random order. The histopathological diagnoses serve as the gold standard. Results In identifying laryngeal malignancy, the sensitivity of NBI proved to be higher than that of WLE (93.3% vs. 77.0%). NBI was also superior to WLE in terms of accuracy (96.3% vs. 92%) and diagnostic odds ratio (501.83 vs. 120.65). Both modalities had a specificity of 97.3%. The inter-observer agreement was substantial (kappa = 0.661) for WLE and almost perfect (kappa = 0.849) for NBI. Both WLE and NBI showed a high level of intra-observer agreement. The sensitivity was significantly lower in images with history of previous laryngeal surgery compared to those without. Conclusions Flexible transnasal endoscopy has been proved to be a valuable tool in the diagnosis of laryngeal malignancy. The use of NBI can increase the sensitivity and observer reliability in that context and can also provide a diagnostic gain in cases with previous laryngeal surgery

Abstract
BACKGROUND The aim of this study was to determine whether tumor-associated immune cells may predict response to therapy and disease outcome in head and neck squamous cell carcinoma (HNSCC) patients receiving induction chemotherapy and cetuximab. METHODS Paraffin-embedded pretreatment biopsy samples from 45 patients with stage III-IV resectable HNSCC were investigated retrospectively by immunohistochemistry for density of different immune cell types based on expression of CD8, FOXP3, CD134, CD137, PD-1, CD20, NKp46, dendritic cell lysosomal-associated membrane protein (DC-LAMP), CD16, CD68, and myeloperoxidase. Results were analyzed for possible correlations with clinicopathologic parameters, response to therapy, and survival. RESULTS Of the immune cell types studied, we found significant association with response to induction chemotherapy only in the case of DC-LAMP+ mature dendritic cells and PD-1+ lymphocytes; density of DC-LAMP+ cells also correlated with progression-free survival. CONCLUSION DC-LAMP+ mature dendritic cells and PD-1+ cells may be implicated in response to induction chemotherapy and cetuximab in HNSCC patients.

Abstract
PROBLEM/CONDITION Tobacco use is the leading preventable cause of cancer, contributing to at least 12 types of cancer, including acute myeloid leukemia (AML) and cancers of the oral cavity and pharynx; esophagus; stomach; colon and rectum; liver; pancreas; larynx; lung, bronchus, and trachea; kidney and renal pelvis; urinary bladder; and cervix. This report provides a comprehensive assessment of recent tobacco-associated cancer incidence for each cancer type by sex, age, race/ethnicity, metropolitan county classification, tumor characteristics, U.S. census region, and state. These data are important for initiation, monitoring, and evaluation of tobacco prevention and control measures. PERIOD COVERED 2010-2014. DESCRIPTION OF SYSTEM Cancer incidence data from CDC's National Program of Cancer Registries and the National Cancer Institute's Surveillance, Epidemiology, and End Results program were used to calculate average annual age-adjusted incidence rates for 2010-2014 and trends in annual age-adjusted incidence rates for 2010-2014. These cancer incidence data cover approximately 99% of the U.S. POPULATION This report provides age-adjusted cancer incidence rates for each of the 12 cancer types known to be causally associated with tobacco use, including liver and colorectal cancer, which were deemed to be causally associated with tobacco use by the U.S. Surgeon General in 2014. Findings are reported by demographic and geographic characteristics, percentage distributions for tumor characteristics, and trends in cancer incidence by sex. RESULTS During 2010-2014, approximately 3.3 million new tobacco-associated cancer cases were reported in the United States, approximately 667,000 per year. Age-adjusted incidence rates ranged from 4.2 AML cases per 100,000 persons to 61.3 lung cancer cases per 100,000 persons. By cancer type, incidence rates were higher among men than women (excluding cervical cancer), higher among non-Hispanics than Hispanics (for all cancers except stomach, liver, kidney, and cervical), higher among persons in nonmetropolitan counties than those in metropolitan counties (for all cancers except stomach, liver, pancreatic, and AML), and lower in the West than in other U.S. census regions (all except stomach, liver, bladder, and AML). Compared with other racial/ethnic groups, certain cancer rates were highest among whites (oral cavity and pharyngeal, esophageal, bladder, and AML), blacks (colon and rectal, pancreatic, laryngeal, lung and bronchial, cervical, and kidney), and Asians/Pacific Islanders (stomach and liver). During 2010-2014, the rate of all tobacco-associated cancers combined decreased 1.2% per year, influenced largely by decreases in cancers of the larynx (3.0%), lung (2.2%), colon and rectum (2.1%), and bladder (1.3%). INTERPRETATION Although tobacco-associated cancer incidence decreased overall during 2010-2014, the incidence remains high in several states and subgroups, including among men, whites, blacks, non-Hispanics, and persons in nonmetropolitan counties. These disproportionately high rates of tobacco-related cancer incidence reflect overall demographic patterns of cancer incidence in the United States and also reflect patterns of tobacco use. PUBLIC HEALTH ACTION Tobacco-associated cancer incidence can be reduced through prevention and control of tobacco use and comprehensive cancer-control efforts focused on reducing cancer risk, detecting cancer early, and better assisting communities disproportionately affected by cancer. Ongoing surveillance to monitor cancer incidence can identify populations with a high incidence of tobacco-associated cancers and evaluate the effectiveness of tobacco control programs and policies. Implementation research can be conducted to achieve wider adoption of existing evidence-based cancer prevention and screening programs and tobacco control measures, especially to reach groups with the largest disparities in cancer rates.

Abstract
Background Laryngeal cancer is one of the major malignancies of the neck and head and is responsible for considerable mortality across the globe. The treatments for laryngeal cancer mainly involve surgical interventions followed by chemotherapy. However, due to unsatisfactory results, constant relapses and the adverse effects associated with the currently used drugs, there is pressing need to develop effective drug options for treatment of laryngeal cancer. Therefore, this study was undertaken to investigate the anticancer effects of a plant-derived alkaloid, Mukonal, against human AMC-HN-8 laryngeal cancer cells. Material/Methods The WST-1 and clonogenic assays were employed to determine the cell viability. Apoptosis was detected by Hoechst and AO/EB staining. Cell migration and cell cycle analysis was performed by Transwell assay and flow cytometry, respectively. Protein expression was examined by Western blotting. Results The results revealed that Mukonal reduced the viability of laryngeal cancer cells dose-dependently. The IC50 of Mukonal was found to be 10 μM. However, the effects of Mukonal on the normal HuLa-PC cells was found to be 140 μM. The decrease in the viability of the AMC-HN-8 laryngeal cancer cells was found to be due to the induction of apoptosis and G2/M cell cycle arrest. Mukonal also suppressed the cell migration and of the AMC-HN-8 laryngeal cancer cells. Mukonal could also inhibit the PI3K/AKT and MEK/ERK signalling pathways in a concentration-dependent manner. Conclusions Taken together, we conclude that Mukonal could prove a beneficial lead molecule for the treatment of laryngeal cancer.

Abstract
ABSTRACT: Laryngeal cancer represents the malignant degeneration, of epithelial nature or from the connective tissue, which starts in the constitutive elements of the larynx. Cancer localization in the larynx represents between 1% and 3% of all malignant tumors and approximately 50% of ear, nose and throat (ENT) tumors. Squamous cell carcinoma is the most common form (around 95%) of laryngeal cancer, with high incidence in human males from southern and central Europe, Romania occupying one of the top places. Material and Methods. Our study consisted of 490 patients diagnosed with laryngeal cancer from 2010 to 2016. They have been clinically, histologically, immunohistochemically, genetically, therapeutically and prognostically analyzed. Suspended microlaringoscopy has been the standard, allowing tumor extension evaluation and biopsy. All specimens were microscopically analyzed in standard or special histology stainings. For unclear histology specimens, immunohistochemical stainings were performed. Results and discussions. Histological types have been represented as follows: 31 carcinomas in situ, 17 microinvasive carcinoma, 205 poorly differentiated carcinomas, 138 moderately differentiated carcinomas, 63 well differentiated carcinomas, 8 papillary carcinomas, 1 leiomyosarcoma, 1 chondrosarcoma, 6 basaloid squamous cell carcinomas, 4 verrucous carcinoma, 1 malignant melanoma. Conclusions. The study brings to light the importance of integrated clinical, morphological and genetic evaluation of laryngeal cancer, regarding tumoral invasion grading and establishing an adequate surgical and oncologic treatment. The importance of immunohistochemistry in laryngeal cancer concerns prognosis factors which correlate with the evolution and histopathological degree of the lesion. The analysis of tumor invasion can lead to the development of therapeutic conduct and the establishment of prognostic markers.

Abstract
OBJECTIVES The aim of our study was to investigate the role of TrkB pathway in tumor occurrence and development for in order to provide theoretical basis to laryngeal cancer therapy. MATERIALS AND METHODS Biological characteristics of the cells were studied by migration tests and colony forming assay. Gene and protein expression analysis was performed by RT-PCR or western blot. in vivo experiments were conducted in syngeneic BALB/c mice. RESULTS Significant changes in protein and gene expression, including higher expression level of TrkB, were found in cells and laryngeal cancer specimens. we demonstrated that TrkB activates AKT via c-Src, leading to increased proliferation. Also, TrkB induced EMT via increased expression of EMT related transcription factors such as Twist-1 and Twist-2. CONCLUSION Our data indicate TrkB are overexpressed in laryngeal cancer, and TrkB signaling is involved in tumorigenicity of laryngeal cancer. These observations suggest that TrkB is a promising target for future intervention strategies to prevent tumor metastasis, EMT program in laryngeal cancer.What is already known about this subject?• Cancer of the larynx is one of the most common types of head and neck cancer.• The survival rate of advanced laryngeal cancer is only 30 to 40%.• The tropomyosin-related kinase B receptor (TrkB), together with TrkA and TrkC, are neurotrophin receptors regulating the proliferation and differentiation of neuronal cells.What are the new findings?• TrkB are overexpressed in laryngeal cancer.• TrkB signaling is involved in tumorigenicity of laryngeal cancer.• TrkB acts as a key regulator of the PI3K/AKT signal pathway-mediated tumor metastasis.How might these results change the focus of research or clinical practice?• These observations suggest that TrkB is a promising target for future intervention strategies to prevent tumor metastasis, EMT program in laryngeal cancer. Our study provides molecular insight into the tumor metastasis and has important implications in elucidating oncogenic processes.

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
A retrospective, longitudinal study of 1,616 patients with primary laryngeal squamous cell carcinoma (LSCC) at a single center in Norway during 1983–2010 was undertaken to investigate overall survival, disease specific survival, disease-free survival, prognostic factors for overall survival, and impact of recurrence among all-stage laryngeal cancer patients over 15 years' follow-up. The prognostic impact of gender, age, smoking/alcohol, subsite, tumour, node and metastasis staging, period and modality of treatment were evaluated using Kaplan-Meier and Cox proportional hazard analyses. The importance of recurrence on survival was assessed based on case fatality rates. Five-year overall survival was 56.8%, 64.0% and 38.8%, and disease-specific survival was 80.2%, 87% and 61.6%, respectively, for the entire cohort and for glottic and supraglottic LSCC. Old age, advanced-stage LSCC and supraglottic cancer were associated with lower overall survival. The risk of disease-specific death plateaued after five years and varied significantly by subsite. Multivariate analysis of glottic LSCC revealed that surgical treatment improved overall survival, whereas old age, alcohol, T3-T4 status, positive N-status and no treatment were associated with worse survival. In supraglottic LSCC, age, alcohol, and positive N-status had a significant impact on overall survival by multivariate analysis. Five-year overall survival and disease-specific survival among patients with recurrent disease were 34% and 52%, respectively. In conclusion, marked difference in overall survival between glottic and supraglottic LSCC underline the importance of subsite-specific survival analysis. T-status and primary surgical management is essential only for glottic LSCC, emphasizing the importance of correct disease classification. Inferior outcomes in supraglottic LSCC are associated with old age, positive N-status, and improved follow-up routines are necessary. Primary tumor control is essential since recurrence impairs survival considerably in all subsites. The potential benefit of a primary surgical approach towards T3 LSCC awaits further investigation.

Abstract
The aim of this analysis is to examine long-term trends in alcohol consumption and associations with lagged data on specific types of cancer mortality, and indicate policy implications. Data on per capita annual sales of pure alcohol; mortality for three alcohol-related cancers - larynx, esophageal, and lip, oral cavity, and pharynx; and per capita consumption of tobacco products were extracted at the country level. The Unobservable Components Model was used for this time-series analysis to examine the temporal association between alcohol consumption and cancer mortality, using lagged data, from 17 countries. Statistically significant associations were observed between alcohol sales and cancer mortality, in the majority of countries examined, which remained after controlling for tobacco use (P<0.05). Significant associations were observed in countries with increasing, decreasing, or stable trends in alcohol consumption and corresponding lagged trends in alcohol-related cancer mortality. Curtailing overall consumption has potential benefits in reducing a number of harms from alcohol, including cancer mortality. Future research and surveillance are needed to investigate, monitor, and quantify the impact of alcohol control policies on trends in cancer mortality.

Abstract
Surgical treatment of laryngeal cancer has been established for decades. In addition to total laryngectomy, which was first performed in 1873, a large number or organ preservation surgical techniques, like open partial laryngectomy, transoral laser microsurgery, and transoral robotic surgery have been developed. Studies on laryngeal cancer surgery are mainly retrospective case series and cohort studies. The evolution of chemoradiation protocols and their analysis in prospective randomized trials have led to an increasing acceptance of non-surgical treatment procedures. In addition to an improvement of prognosis, in recent years the preservation of function and maintenance of life quality after primary therapy of laryngeal cancer has increasingly become the focus of therapy planning. Significant late toxicity after chemoradiation has been identified as an important issue. This leads to a reassessment of surgical concepts and initiation of studies on laryngeal cancer surgery which was additionally stimulated by the advent of transoral robotic surgery in the US. Improving the evidence base of laryngeal cancer surgery by successful establishment of surgical trials should be the future goal.

Gene/protein expression of CAPN1/2-CAST system members is associated with ERK1/2 kinases activity as well as progression and clinical outcome in human laryngeal cancer. Tumour Biol 2016; 37:13185-13203.

Abstract
Recent evidence indicates the involvement of calpains (CAPNs), a family of cysteine proteases, in cancer development and progression, as well as the insufficient response to cancer therapies. The contribution of CAPNs and regulatory calpastatin (CAST) and ERK1/2 kinases to aggressiveness, disease course, and outcome in laryngeal cancer remains elusive. This study was aimed to evaluate the CAPN1/2-CAST-ERK1/2 enzyme system mRNA/protein level and to investigate whether they can promote the dynamic of tumor growth and prognosis. The mRNA expression of marker genes was determined in 106 laryngeal cancer (SCLC) cases and 73 non-cancerous adjacent mucosa (NCLM) controls using quantitative real-time PCR. The level of corresponding proteins was analyzed by Western Blot. SLUG expression, as indicator of pathological advancement was determined using IHC staining. Significant increases of CAPN1/2-CAST-ERK1/2 levels of mRNA/protein were noted in SCLC compared to NCLM (p < 0.05). As a result, a higher level of CAPN1 and ERK1 genes was related to larger tumor size, more aggressive and deeper growth according to TFG scale and SLUG level (p < 0.05). There were also relationships of CAPN1/2 and ERK1 with incidences of local/nodal recurrences (p < 0.05). An inverse association for CAPN1/2, CAST, and ERK1/2 transcripts was determined with regard to overall survival (p < 0.05). In addition, a higher CAPN1 and phospho-ERK1 protein level was related to higher grade and stage (p < 0.05) and was found to promote worse prognosis. This is the first study to show that activity of CAPN1/2- CAST-ERK1/2 axis may be an indicator of tumor phenotype and unfavorable outcome in SCLC.

Abstract
AIM To describe the incidence, disease-specific mortality (DSM), and overall survival (OS) of patients with glottic squamous cell carcinomas (SCC) in Denmark from 1971-2011 in a national population-based cohort of consecutive patients. MATERIALS AND METHODS All patients diagnosed with glottic SCC stage I-IV between 1971 and 2011 in Denmark were included. Patients were identified from the Danish Head and Neck Cancer database, which has a coverage of approximately 100% of registered glottic cancer in Denmark. Information on vital status and cause of death were updated using patient charts and national registries. RESULTS In total 5132 patients with glottic SCC were included. The yearly number of new cases increased from 107 in the 1970s to 139 in the 2000s. Overall, the incidence increased from 1.9 to 2.6 per 100,000, with a more prominent increase in men (3.5 to 4.7) compared with women (0.4 to 0.6). The 5-year DSM was 16% (15-17%) and the 5-year OS was 63% (61-64). The hazard rate of DSM adjusted for patient characteristics, tumour characteristics and waiting-time was significantly lower in the 2000s (p < 0.01), and the hazard rate of OS was significantly higher (p < 0.01) compared to the earlier decades. Longer waiting-time for treatment (>25 d) significantly increased DSM and reduced OS. CONCLUSION Despite being highly avoidable with smoking cessation, the incidence of glottic SCC increased in Denmark from 1971-2011. The adjusted hazard rate of DSM and overall death after glottic SCC was significantly lower in the 2000s compared to previous decades. Waiting-time for treatment significantly influenced DSM and OS.

Abstract
Laryngeal cancer is about the twentieth most common cancer in the world and more than 150,000 new cases are diagnosed annually. The aim of the study was to evaluate the history, diagnostics, treatment outcomes, and prognosis in patients with laryngeal cancer in Northern Slovakia. We analyzed retrospectively 227 patients (207 males, 20 females) with laryngeal carcinoma treated in the period 2003-2014 at the Clinic of Otorhinolaryngology and Head and Neck Surgery of the Jessenius Faculty of Medicine and Martin University Hospital in Martin, Slovakia. The majority of patients were in the sixth (38.0 %) and seventh decade of life (30.8 %). Two hundred and seventeen patients (95.6 %) were smokers or ex-smokers. Sixty-six percent of patients were diagnosed with glottic or transglottic carcinoma, related probably to the anatomical structure of the larynx and exposure to inhalation pollutants. It is alarming that the majority of patients with malignant laryngeal disease were admitted to the hospital in advanced stages. In 151 (66.5 %) of patients, the extent of infiltration was T3 or T4, and 156 (68 %) patients were in disease stage III and IV. The incidence and mortality of laryngeal cancer suggest the need to intensify the prevention and to search for an early clinical stage of laryngeal cancer using a targeted screening.
