Background: Tumor microenvironments affect the progression of cancers. Results: We demonstrated that Th17 cells were accumulated in tumor tissues, and the tumor-derived MIF induced Th17 cell accumulation and had clinical relevance in NPC.
Conclusion:The cytokine MIF regulates intratumoral Th17 cell expansion and has prognostic value for NPC patients. Significance: The tumor microenvironment influences the clinical prognosis of NPC patients.
