It revealed a significant association between increased UCA1 and OS in patients with GC (pooled HR = 2.32, 95% CI 1.61–3.33, p < 0.001), CRC (pooled HR = 2.16, 95% CI 1.29–3.62, p = 0.004), HCC (pooled HR = 1.89, 95% CI 1.20–3.00, p = 0.007), and PAC (pooled HR = 1.60, 95% CI 1.16–2.22, p = 0.004). The gene discussed is UCA1; the disease is colorectal carcinoma.
