In order to identify key lncRNAs in NPC relapse, we conducted Venn diagram screening on the genelist results of the above three groups, and found that there were 5 common lncRNA genes (AL022724, AC006064, TERC, AC025569, AC130456) differential expression in the three groups, which may have a pivotal role in NPC progression. The gene discussed is TERC; the disease is nasopharyngeal carcinoma.
