Actually, previous researchers have identified lncRNAs as prognostic markers of PTC, such as TTTY10 (Chen et al., 2019), LINC00284, RBMS3-AS1, and ZFX-AS1 (Zhao et al., 2018) and five lncRNAs of PPARG, E2F1, CCND1, JUN, and EZH2 (Sun et al., 2020) for predicting tumor recurrence in PTC. This evidence concerns the gene CCND1 and neoplasm.
