Distant metastases (DM) is the point of concern and seems to be on the rise with the improved control of the laryngeal cancer in the primary site and neck regions. Prognostic factors must be evaluated to improve the detection of DM at early stage of the disease. Therefore, we have analyzed our cases of laryngeal squamous cell carcinoma with DM to find out the risk factors in these patients. We analyzed the records of laryngeal squamous cell carcinoma patients with DM. The records were evaluated according to distant metastases site, TNM staging, the metastases at the neck, treatment and survival. The incidence of DM was 7.2% in our series. Lung is the most common site of DM in laryngeal squamous cell carcinoma. Staging grouping has been helpful in predicting DM, most of the cases were in stage III and IV (85%). Supraglottic lesions is the most common site in patients with DM. The recurrence in the locoregional site was observed in 47% of cases. The overall survival with DM is 28 months, without DM 22 months. The patients with DM in laryngeal squamous cell carcinoma were from the group with supraglottic lesions, stage 3, 4a and 4b. Stage grouping seems to be a better indicator of DM rather than T or N stage alone. The most common site of metastasis is the lung.

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.
