CD8/CD4 ratio, CD56, and PD-L1 as prognostic markers in sinonasal mucosal melanoma

Key Points

• CD8/CD4 ratio and PD-L1 levels provide significant prognostic information for sinonasal melanoma.
• Higher CD56 expression correlates with improved prognosis compared to lower levels in examined cases.
• Analysis involves measuring immune marker levels in tumor tissues of sinonasal melanoma patients.
• Identifying effective prognostic markers may improve patient management and treatment strategies.
