Objective: To analyze the changes in tumor necrosis factor receptor superfamily (TNFRSF) 4 expression levels in laryngeal squamous cell carcinoma (LSCC) patients through multiple database data combined with clinical samples, and to study the role of TNFRSF4 in the occurrence and development of LSCC. Method: Based on Gene Expession Omnibus (GEO) database and The Cancer Genome Atlas (TCGA) database, the differentially expressed gene was screened out. The expression level prediction and survival analysis of TNFRSF4 were performed using Gene Expression Profiling Interactive Analysis (GEPIA) database. Western blot and qRT-PCR were performed on LSCC and adjacent tissue samples from three patients. K-M curve was drawn based on TCGA clinical data, and Cox regression analysis was performed. Finally, gene set enrichment analysis was performed to explore signaling pathways related to the role of TNFRSF4 in LSCC. Results: In the database and clinical samples, the expression of TNFRSF4 in the LSCC group was higher than that in the normal group (P＜0.05), and the survival rate of the high TNFRSF4 expression group was higher than that of the low TNFRSF4 expression group (P＜0.01). Multivariate Cox regression analysis showed that the expression level of TNFRSF4 (HR: 0.430, 95%CI: 0.229-0.806, P=0.009), gender (HR: 0.424, 95%CI: 0.204-0.882, P=0.022), lymph node staging (HR:2.010, 95%CI: 1.055-3.831, P=0.034) and distant metastasis (HR: 3.706, 95%CI: 1.152-11.922, P=0.028) collectively affect the overall survival time of patients. The results of gene set enrichment analysis showed that the most significantly correlated signaling pathways with TNFRSF4 expression included cell adhesion molecule, JAK-STAT signaling pathway, T cell receptor signaling pathway, B cell receptor signaling pathway, primary immunodeficiency, and autoimmune thyroid disease. Conclusion: High expression of TNFRSF4 may be a biomarker for good prognosis of patients with LSCC.

Objective: To compare the therapeutic effects of low-temperature plasma radiofrequency ablation and partial laryngectomy in the treatment of early glottis carcinoma., Methods: Clinical data of 80 patients with early glottis carcinoma treated in our hospital from June 2019 to January 2021 were analyzed. Patients were retrospectively divided into two groups based on the type of intervention. Forty patients received partial laryngectomy (Control group) and 40 patients received low-temperature plasma radiofrequency ablation (Observation group). Surgical indexes, length of hospital stay, postoperative complications, and visual analog scale (VAS) score of postoperative pain of patients in the two groups were compared. Postoperative stress response indexes, clinical efficacy, and postoperative recovery in two groups were compared and analyzed., Result: The operation time, hospital stay, intraoperative bleeding, and the incidence of postoperative complications in the observation group were significantly lower than those in the Control group ( P <0.05). The postoperative pain VAS scores, Levels of malondialdehyde (MDA) and glutathione (GSH) in the observation group were significantly lower than those in the control group ( P <0.05), while the level of nitro tyrosine (3-NT) and superoxide dismutase (SOD) were significantly higher than that in the control group ( P <0.05). After a one-year follow-up, the excellent and good rate of pronunciation function in the observation group (95%) was significantly higher than control group (75%) ( P <0.05)., Conclusions: Low-temperature plasma radiofrequency ablation in the treatment of early glottis carcinoma is associated with less trauma, short operation time, less bleeding, short hospital stay and low postoperative stress reaction rate. Compared with partial laryngectomy, it has higher safety and better postoperative vocal cord function recovery., Competing Interests: Conflict of interest: None., (Copyright: © Pakistan Journal of Medical Sciences.)
