Background: In laryngeal carcinoma, regional nodal metastasis serves as a significant prognostic factor. A special biomarker is needed to predict the status of nodal metastases. N-cadherin, a binding protein, aids in cell migration and enabling tumor cells to spread to new locations. The involvement of matrix metalloproteinase-9 (MMP-9) in metastasis includes fostering the dissemination of tumor cells from the primary tumor and enhancing tumor cell motility. Objective: This study seeks to explore the distinctions and relationships in N-cadherin and MMP-9 expression among patients with laryngeal squamous cell carcinoma at various N stages. Methods: Employing a cross-sectional approach, this study conducted an analytic observational investigation on formalin-fixed paraffin-embedded patients whose histopathological diagnosis is laryngeal squamous cell carcinoma in the Pathology Laboratory of Dr. Soetomo Regional Public Hospital in 2018{\textendash}2021. The samples were divided into N stages based on radiological imaging from the CT scan. Immunohistochemistry examinations were performed using N-cadherin and MMP-9 antibodies and scored using the immunoreactive score (IRS), based on percentage and intensity. The differences in expression and correlation between N-cadherin and MMP-9 were analyzed using statistical tests. Results: Statistical insignificance was observed in N-cadherin expression at various N stages (p = 0.099). There were significant differences in MMP-9 expressions at various N stages (p = 0.0006338). There was no correlation between N-cadherin and MMP-9 expression at various N stages in laryngeal squamous cell carcinoma (p = 0.0638, rs = 0.27). Conclusion: In laryngeal squamous cell carcinoma, MMP-9 serves as a predictor for lymph node metastasis, which, if present, deteriorates the patient{\textquoteright}s prognosis.

Background: COVID-19 has spread rapidly around the world. It is necessary to study lung tissue of postmortem COVID19 patients to determine the molecular alteration particularly the role of IL-6 and IL-17 in causing fatality. Objective: This study aims to determine the differences in the expressions of IL-6 and IL-17 in lung tissue of post-mortem COVID-19 patients compared to non-COVID-19 patients. This study also aimed to analyze the correlation between the expressions of IL-6 and IL-17 in lung tissue of post-mortem COVID-19 patients. Methods: This research is an observational analytic study with crosssectional approach. The samples were 15 paraffin blocks of post-mortem lung tissue biopsy of COVID-19 patients, and 15 paraffin blocks of inflammatory lung tissue biopsy or surgery of non-COVID-19 patients. IL-6 and IL-17 expressions were evaluated by immunohistochemical procedure. Result: There was a significant difference in the expression of IL-6 in the COVID-19 group and the non-COVID-19 group with a p-value = 0.001 (p \< 0.05). There was a significant difference in the expression of IL-17 in the COVID-19 group and the non-COVID-19 group with p-value = 0.001 (p \< 0.05). There was a significant correlation between the expressions of IL-6 and IL-17 in the COVID-19 group, with the Spearman coefficient value (rs) of 0.548 with p = 0.034 (p \< 0.05). Conclusion: There are differences in the expression of IL-6 and IL-17 between COVID-19 and non-COVID-19 lung tissue. There is a significant correlation between the expressions of IL-6 and IL-17 in post-mortem lung tissue of COVID-19 patients.
