Ding W, Cai W, Wang H. P53 and pRB induction improves response to radiation therapy in HPV-positive laryngeal squamous cell carcinoma. Clinics (Sao Paulo) 2024; 79:100415. [PMID: 38897099 PMCID: PMC11237859 DOI: 10.1016/j.clinsp.2024.100415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 04/19/2024] [Accepted: 06/03/2024] [Indexed: 06/21/2024] Open
Abstract
INTRODUCTION Patients with Human Papillomavirus (HPV+)-associated Laryngeal Squamous Cell Carcinoma (LSCC) exhibit dramatically improved survival relative to those with HPV-Negative (HPV-) tumors. In this study, the authors aimed to investigate the radiosensitivity of all available confirmed HPV+ and HPV-LSCC cells in vitro and in vivo. METHODS Primary LSCC cells were generated from tumor specimens obtained from patients. Real-time PCR was performed to confirm HPV infection and the expression of HPV-related genes (E6 and E7), p53, and pRB. Clonogenic survival assays, western blotting, and flow cytometry were used to assess radiation sensitivity, apoptosis, and the expression of p53 and pRB. p53 and pRB knockout cells were generated using CRISPR/Cas9 technology. RESULTS HPV+ LSCC cells displayed enhanced radiation sensitivity compared to HPV- cells. Radiation-induced apoptosis in HPV+ LSCC cells, accompanied by increased levels of p53 and pRB. Knockout of p53 or pRB led to radiation resistance and attenuated radiation-induced apoptosis in HPV+ LSCC cells. In vivo experiments showed similar results, where knockout of p53 or pRB decreased radiosensitivity in tumor-bearing mice. CONCLUSION The present findings demonstrated that HPV+ LSCC cells displayed obvious inherent radiation sensitivity, corresponding to increased apoptosis following radiation exposure. Mechanism study showed that the expression of p53 and pRB in HPV+ cells are required for radiation sensitivity. These findings highlight a novel mechanism by which p53 and pRB play key roles in the radiation sensitivity of HPV+ LSCC compared to HPV-LSCC.

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.

Abstract
Objective This study investigates the overall survival (OS) of elderly patients who underwent total laryngectomy for laryngeal cancer (LC) and examines the impact of tumor-node-metastasis (TNM) staging on survival rates. Methods A retrospective cohort study utilized data from the Otorhinolaryngology Clinic at the University Hospital of Patras, including 75 elderly patients (>65 years) who underwent total laryngectomy for LC between 2000 and 2015. Survival analysis was performed using the Kaplan-Meier estimator, with comparisons made using the Log-rank test. Statistical significance was defined as the p-value being less than or equal to 0.05. Results Over the 16-year period, new LC cases were predominantly male (97.3%) with a mean age of 73.88 years (range: 65-89 years). Most patients were smokers (96%) and alcohol users (54.7%). Histologically, 18.7% of tumors were classified as poorly differentiated, 65.3% as moderately differentiated and 16% as well differentiated. Post-surgical TNM staging indicated 10.7% stage II, 37.3% stage III and 52% stage IV, primarily located in the glottis (62.7%) and followed by supraglottis (34.7%). All patients underwent total laryngectomy, with 69.3% and 37.3% receiving neck dissection and adjuvant therapy (chemotherapy or radiotherapy), respectively. During follow-up, 39 patients died, with 74.3% due to disease-related causes. Five-year OS rates were 44.6%, with variations by stage (stage II: 62.5%, stage III: 55.8%, stage IV: 32.4%; p=0.039) and age (65-75 years: 51.7%, >75 years: 34.7%; p=0.039). Conclusions TNM staging of the laryngeal cancer significantly influences the overall survival of elderly patients undergoing total laryngectomy for LC. Early diagnosis of the disease is crucial for patient survival.

Abstract
BACKGROUND Laryngeal cancer (LC) is among of the most frequent head and neck cancers, associated to a high social impact and mortality. Unfortunately, the current treatment outcomes of LC are often scant, with different factors affecting patient's prognosis (i.e., advanced age, advanced disease stage, lymph node involvement, tumor pathological features, type of intervention). The aims of the present study were: 1) to evaluate the epidemiological and clinical features of patients affected by LC; and 2) to focus on tumor risk factors affecting patient's overall survival (OS) and recurrences. METHODS A retrospective analysis of all patients affected by LC and surgically treated at two different hospital settings has been performed. RESULTS Two hundred twenty-five patients were enrolled in the present study; of these 189 were males (84%) and 36 (16%) were females. The most frequently performed surgery was total laryngectomy. Thirty-two (14.2%) patients experienced local recurrence, while 15 patients (6.6%) had regional recurrence and 15 distant metastases. Multivariate analysis showed that locoregional recurrence was associated to the occurrence of distant metastases (P=0.002, HR=25,35). Analyzing OS, the only statistically significant factor that correlated with an increased risk of mortality (P<0.015, HR=2,45) was locoregional recurrence. CONCLUSIONS The present study confirms the literature data about age and sex distribution of LC, about tumors localization, lymph nodes metastasis and distant metastasis incidence and OS rate, based on T and N stage. Interestingly, within this series, the presence of locoregional recurrence or distant metastasis is related to a worst prognosis and a lower overall survival rate.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is one of the common malignant tumors in the head and neck region, and its high migration and invasion seriously threaten the survival and health of patients. In cancer development, m6A RNA modification plays a crucial role in regulating gene expression and signaling. This study delved into the function and mechanism of the m6A reading protein YTHDF1 in LSCC. It was found that YTHDF1 was highly expressed in the GEO database and LSCC tissues. Cell function experiments confirmed that the downregulation of YTHDF1 significantly inhibited the proliferation, migration, and invasion ability of LSCC cells. Further studies revealed that EIF4A3 was a downstream target gene of YTHDF1, and knockdown of EIF4A3 similarly significantly inhibited the malignant progression of LSCC in both in vivo and in vitro experiments. The molecular mechanism studies suggested that YTHDF1-EIF4A3 may promote the malignant development of LSCC by activating the EMT signaling pathway. This study provides important clues for an in-depth understanding of the pathogenesis of LSCC and is a solid foundation for the discovery of new therapeutic targets and approaches.

Abstract
OBJECTIVES To evaluate the association between statin use and chronic rhinosinusitis (CRS). DESIGN AND SETTING Systematic review and meta-analysis. The methodological quality of studies was assessed using the Newcastle-Ottawa scale. PARTICIPANTS Patients with CRS. MAIN OUTCOME MEASURES Pooled odds ratios (ORs) with 95% confidence interval (CIs) in analyses of studies that compared the prevalence of CRS, nasal polyp, difference of Lund-Kennedy endoscopic score, Lund-Mackay CT score and Sino-nasal Outcome Test-22. RESULTS The analysis included eight studies and 445 465 patients. Patients who used statins were at lower risk for CRS than those who did not (OR = 0.7457, 95% CI = 0.6629-0.8388, p < 0.0001, I2 = 0.0%). Patients with hyperlipidaemia were at higher risk for CRS than those with normal serum levels of lipid (OR = 1.3590, 95% CI = 1.2831-1.4394, p < 0.0001, I2 = 33.3%). However, there were no significant differences in the risk for nasal polyps between CRS patients using statins or not (OR = 1.0931, 95% CI = 0.7860-1.5202, p = 0.5968, I2 = 0.0%). Additionally, statin use was not related to Lund-Kennedy endoscopic scores, Lund-Mackay CT scores or sino-nasal outcome test-22 scores in CRS patients. CONCLUSION The risk for CRS is lower in patients who use statins and those without hyperlipidaemia.
