AI Article Synopsis
- The study evaluates the effectiveness of autofluorescence laryngoscope (AFL) in diagnosing early laryngeal carcinoma and precancerous lesions compared to the traditional white light laryngoscope (WL).
- A comprehensive search through various databases led to the inclusion of 23 studies, which showed that AFL had higher sensitivity (0.91) and specificity (0.80) than WL (sensitivity of 0.74 and specificity of 0.89).
- The findings suggest that AFL has better diagnostic accuracy and should be considered for early detection of laryngeal conditions, outperforming WL in diagnostic value.
Article Abstract
Objective: We aim to evaluate the diagnostic value of autofluorescence laryngoscope (AFL) in early laryngeal carcinoma and precancerous lesions. aWe also assess the value of AFL in diagnosis of early laryngeal carcinoma and precancerous lesions in comparison with that of white light laryngoscope (WL).
Methods: The databases consisting of PubMed, Cochrane Library, Web of science and CNKI were systematically searched to find pertinent literatures of AFL in diagnosing early laryngeal carcinoma and precancerous lesions. We made a quality evaluation of every study we included using the modified Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). The pooled sensitivities, specificities were calculated using Meta-Disc 1.4. And we estimated the summary receiver operating characteristic curves (SROC) and area under the curves (AUC).
Results: We finally included 23 studies. The results of AFL in diagnosing early laryngeal carcinoma and precancerous lesions showed higher sensitivity of 0.91 (95%CI: 0.89-0.93; χ²=43.78, p = 0.0025) and specificity of 0.80 (95%CI: 0.77-0.82; χ²=130.64, p = 0.000), and the weighted AUC of AFL was 0.948 ± 0.013 (95%CI: 0.921-0.974) and the diagnostic accuracy (Q*) was 0.887 ± 0.018. The sensitivity and specificity of WL were 0.74 (95%CI: 0.70-0.77; χ²=52.40, p = 0.000) and 0.89 (95%CI: 0.87-0.90; χ²=299.22, p = 0.000), and the weighted AUC of WL was 0.835 ± 0.029 (95%CI: 0.777-0.892) and the diagnostic accuracy (Q*) was 0.767 ± 0.027.
Conclusion: The meta-analysis and systematic review suggested that AFL had high diagnostic value in early laryngeal carcinoma and precancerous lesions, and its diagnostic value was higher than that of WL. These results indicated that AFL can provide good guidance for the early detection of laryngeal carcinoma and precancerous lesions.

Objectives: The aim of this study was to investigate the role of lymph node yield (LNY), lymph node ratio (LNR), and neutrophil to lymphocyte ratio (NLR) as prognostic factors, their impact on survival in patients with advanced laryngeal squamous cell carcinoma (LSCC).
Methods: This multicentric retrospective study included 195 patients with clinical N0 advanced laryngeal carcinoma who underwent total laryngectomy and/or total pharyngolaryngectomy over 5 years. The number of lymph nodes extracted (LNY) and the number of positive nodes were counted.

Background: Tumor-derived small extracellular vesicles (sEVs) play an essential role in reprogramming the tumor microenvironment. Metabolic reprogramming is an essential prerequisite for M2 polarization of tumor-associated macrophages (TAMs). This M2 phenotype is closely related to the immune dysfunction of CD8 T cells and subsequent tumor progression.

Laryngeal squamous cell carcinoma (LSCC), which represents a significant proportion of head and neck squamous cell carcinoma cases, is often diagnosed at advanced stages, underscoring the urgent need for effective biomarkers and therapeutic targets. Junctional adhesion molecule 3 () is implicated in various types of cancer; however, its role in LSCC remains unclear. Therefore, the present study aimed to investigate the epigenetic regulation and tumor‑suppressive functions and mechanisms of in LSCC.

DCUN1D5 is up-regulated and promotes tumor progression in many cancers such as laryngeal squamous cell carcinoma and breast cancer, but the expression of DCUN1D5 in lung adenocarcinoma and its molecular mechanism are not clear. The differences of DCUN1D5 expression between lung adenocarcinoma and normal tissues were compared by TCGA, GEO and UALCAN databases, and the relationship between DCUN1D5 expression and clinicopathological features of patients was analyzed. The diagnostic and prognostic value of DCUN1D5 in patients with LUAD was analyzed by TCGA, GEPIA and Kaplan-Meier Plotter database.

Article Synopsis
- LINC01133 is a long non-coding RNA (lncRNA) that plays crucial roles in cancer, with this study focusing on its expression and impact in laryngeal squamous cell carcinoma (LSCC).
- Integrative analysis of genetic data revealed LINC01133 is significantly downregulated in LSCC compared to normal tissues, and lower levels are linked to advanced tumor stages and lymph node metastasis.
- The study suggests that LINC01133 may act as a tumor suppressor by disrupting microRNA interactions, indicating its potential diagnostic and therapeutic importance in LSCC.
