Based on the IHC scores of DNAJA4 in NPC tissues, we divided these patients into the low DNAJA expression group and the high DNAJA4 expression group for Kaplan-Meier analysis, and the survival curves demonstrated that the low DNAJA4 expression group had lower relapse-free, distant metastasis-free and overall survival rates than the high DNAJA4 expression group (Fig. 8C–E). This evidence concerns the gene DNAJA4 and nasopharyngeal carcinoma.
