MALAT1 and neoplasm: Results confirmed that MFS of patients with low Δsv-MALAT1-expressing tumours (5-year RFS 70.3±2.5% 10-year RFS 58.5±2.8% 15-year RFS 51.4±3.0%) was shorter than that of patients whose tumours highly expressed Δsv-MALAT1 (5-year RFS 85.9±3.5% 10-year RFS 82.3±3.9% 15-year RFS 76.0±5.1% P=0.000015; Figure 3B).
