When sorted by cancer type, TUG1 expression significantly predicted unfavorable OS in gastrointestinal cancer (HR = 2.12, 95% CI: 1.69-2.67, p < 0.001), urinary tumors (HR = 1.89, 95% CI: 1.27-2.79, p = 0.002), gynecologic tumors (HR = 2.01, 95% CI: 1.40-2.89, p < 0.001), hematological tumors (HR = 2.44, 95% CI: 1.87-3.18, p < 0.001), and osteosarcoma (HR = 1.58, 95% CI: 1.16-2.14, p = 0.003). This evidence concerns the gene TUG1 and osteosarcoma.
