Immune infiltration analysis demonstrated that NOP2 expression is significantly correlated with varying levels of immune cell infiltration, including a positive association with myeloid-derived suppressor cells (MDSCs), M1 macrophages, and natural killer cells and a negative correlation with regulatory T cells and M2 macrophages. NSUN6 expression showed a significant positive correlation with MDSC infiltration. Clinical sample analysis indicated that NOP2 expression is strongly associated with tumor grade and nerve invasion, whereas NSUN6 is significantly related to nerve invasion. Survival analyses revealed that high levels of NOP2 and NSUN6 are linked to shorter overall survival.
