To explore if the correlation between the differential expression of ULPB4 in NPC and the clinical outcomes, we made a comparison of survival outcomes, including 5-year OS, DFS, LRFS, and DMFS rates, between NPC patients with low and high ULBP4 expression, by univariate log-rank survival analysis. The gene discussed is RAET1E; the disease is nasopharyngeal carcinoma.
