Survival analysis via Kaplan-Meier curve has shown association between high DLX6-AS1 expression and shorter overall survival (OS), and/or disease-free survival (DFS) in several types of cancer like HCC (Liu et al., 2020a; Zhang et al., 2017), gastric cancer (Qian et al., 2021; Fu et al., 2019), glioma (Zhang et al., 2019b), breast cancer (Zhao et al., 2019), and several others (Table 3). This evidence concerns the gene DLX6 and central nervous system cancer.
