Additionally, we identified a few of lncRNAs expression levels are significantly associated with thyroid cancer patients OS or RFS time, such as RUNDC3A‐AS1, FOXD‐AS1, PAX8‐AS1, and CRYM‐AS1, suggesting that lncRNAs could be useful prediction factors for thyroid cancer patients survival. The gene discussed is RUNDC3A; the disease is thyroid cancer.
