Further, evidence confirms that potential prognostic markers also exist in other cancers, such as LINC01234 in NSCLC (Chen et al., 2020d), miR-744-5p in ovarian cancer (Kleemann et al., 2018), lncRNA LNCAROD in head and neck squamous cell carcinoma (Ban et al., 2020), lncRNA PVT1 in osteosarcoma (Chen et al., 2020a), miR-25-3p (Zhang et al., 2019a)and lncRNA DANCR (Hu et al., 2020)in pancreatic cancer (see Figure 2). Here, PVT1 is linked to osteosarcoma.
