Abstract
Laryngeal cancer comprises 30%-40% of head and neck malignancies, and it is the most common malignancy in otolaryngology. The main risk factors for laryngeal cancer are tobacco use, excessive alcohol consumption, gastroesophageal reflex, Plummer-Vinson syndrome, exposure to heat, chemicals, and some viral infections. This literature review summarizes all known data over the past decade with an assessment of the main etiological factors related to cancer incidence, general measurement issues in the cancer epidemiology and the current state of science in relation to laryngeal cancer. The geographical distribution of laryngeal cancer also reveals some important aspects. Europe remains the most prevalent continent for this type of malignancy, whilst the epidemiologic burden in Africa remains low. Overall, there are clear differences in morbidity and mortality from laryngeal cancer between urban and rural areas, with gender inequalities. In some countries, the incidence rates are high in rural areas, and in some, such as in China, the urban population is more affected. High rates of laryngeal cancer are closely associated with both low average income and a high percentage of the population with lower-than-average education countries with higher Socio-demographic Index (SDI) have made greater improvements in the treatment of LC than countries with lower SDI. Epidemiological data on risk factors can provide valuable information for developing cancer prevention strategies.

LIN CHUANG ER BI YAN HOU TOU JING WAI KE ZA ZHI = JOURNAL OF CLINICAL OTORHINOLARYNGOLOGY, HEAD, AND NECK SURGERY 2023; 37:354-359. [PMID: 37138397 PMCID: PMC10495781 DOI: 10.13201/j.issn.2096-7993.2023.05.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Indexed: 05/05/2023]
Abstract
Objective:To analyze the risk factors of recurrence and canceration for premalignant vocal fold lesions after surgery, and to provide a reasonable basis for preoperative evaluation and postoperative follow-up. Methods:This study retrospective analyzed the relationship between clinicopathological factors and clinical outcome(recurrence, canceration, recurrence-free survival, and canceration-free survival) in 148 patients undergoing surgical treatment in Chongqing General Hospital from 2014 to 2017. Results:The five-year overall recurrence rate was 14.86% and the overall recurrence rate was 8.78%. Univariate analysis showed that smoking index, laryngopharyngeal reflux and lesion range were significantly associated with recurrence(P<0.05), and smoking index and lesion range were significantly associated with canceration(P<0.05). Multivariate logistic regression analysis showed that smoking index ≥600 and laryngopharyngeal reflux were independent risk factors for recurrence(P<0.05), and smoking index ≥600 and lesion range ≥1/2 vocal cord were independent risk factors for canceration(P<0.05). The mean carcinogenesis interval for the postoperative smoking cessation group was significantly longer(P<0.05). Conclusion:Excessive smoking, laryngopharyngeal reflux and a wide range of lesions may be related to postoperative recurrence or malignant progression of precancerous lesions in the vocal cord, and further large-scale multi-center prospective randomized controlled studies are needed to clarify the effects of the above factors on recurrence and malignant changes in the future.

Epidemiological, Clinical, and Oncological Outcomes of non-Alcohol Drinking and non-Smoking Laryngeal Squamous Cell Carcinoma Patients: A Distinct Entity.

Abstract
Purpose: To explore the discrepancy in clinicopathological and prognostic features between smoking and alcohol drinking (SA) and non-smoking and non-alcohol drinking (NSNA) patients with laryngeal squamous cell carcinoma (LSCC). Methods: This retrospective study including 1735 patients with LSCC was conducted from January 2005 to December 2010, which were categorized into 4 groups, NSNA group, smoking only group, alcohol-drinking only group, and SA group. We compared overall survival (OS) and disease-free survival (DFS) using the Kaplan-Meier method and indicated clinicopathological features by Cox proportional hazards regression models before and after propensity score matching (PSM). Results: A total of 415 patients (23.92%) were identified as NSNA. The SA group was predominantly patients ≤60 years old (46.63%) while the NSNA group was more older (58.07%). NSNA group was more likely to present at earlier disease stage and more female. No significant difference in OS (P = .685) and DFS (P = .976) was found between the 2 groups. In addition to age and recurrence and metastasis being common independent prognostic factors in terms of OS in both groups of patients, NSNA group also exhibited other factors, namely tumor area >3.7 cm2 and positive resection margin. For DFS, N + stage, tumor size >3.7 cm2, and positive resection margin were prognostic features specific to NSNA group. Conclusion: The outcome is similar in LSCC patients with and without SA. NSNA group shows a distinct profile from that found in SA group. Clinicopathological features from NSNA group should be considered for LSCC management.

Abstract
BackgroundLaryngeal cancer is a type of head and neck tumor with a poor prognosis and survival rate. The new cases of laryngeal cancer increased rapidly with a higher mortality rate around the world.ObjectiveThe current research work was focused to unveil the in vitro antitumor effects of ononin against the laryngeal cancer Hep-2 cells.MethodologyThe cytotoxic effects of ononin against the laryngeal cancer Hep-2 cells and normal HuLa-PC laryngeal cells were studied using an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. The intracellular Reactive Oxygen Species (ROS) generation, apoptotic cell death, Mitochondrial Membrane Potential (MMP), and cell adhesion on the 25 and 50 µM ononin-treated Hep-2 cells were detected using respective staining assays. The levels of TBARS and antioxidants were assayed using specific kits. The expressions of c-Jun N-terminal kinase 1/2 (JNK1/2), Extracellular Signal-regulated Kinase 1/2 (ERK1/2), p38, Phosphatidylinositol-3 Kinase 1/2 (PI3K1/2), and protein kinase-B (Akt) in the ononin-treated Hep-2 cells were investigated using Reverse Transcription-Polymerase Chain Reaction (RT-PCR) assay.ResultsThe ononin treatment effectively inhibited the Hep-2 cell viability but did not affect the viability of HuLa-PC cells. Furthermore, the ononin treatment effectively improved the intracellular ROS accumulation, depleted the MMP, and triggered apoptosis in Hep-2 cells. The Thiobarbituric acid reactive substances (TBARS) were improved, and Glutathione (GSH) levels and Superoxide dismutase (SOD) were depleted in the ononin-administered Hep-2 cells. The ononin treatment substantially inhibited the JNK/ERK/p38 axis in the Hep-2 cells.ConclusionTogether, the outcomes of this exploration proved that the ononin has remarkable antitumor activity against laryngeal cancer Hep-2 cells.
