The adjusted ORs of the 5 identified prognostic lncRNAs, in particular, indicated that the up-regulation of CASC2 (OR = 1.225, 95%CI 1.061–5.025), AL078459.1 (OR = 2.923, 95% CI 1.504–7.946), AL390066.1, (OR = 2.311, 95% CI 1.182–4.764) STK4-AS1 (OR = 3.611, 95% CI 1.328–3.030) and HOXA-AS3 (OR = 2.511, 95% CI 1.026–4.415) may be associated with the development of tumor recurrence of CA. The gene discussed is CASC2; the disease is cancer.
