We found high UCA1 expression was associated with high grade cancer (pooled OR = 2.74, 95% CI 2.04–3.70, p < 0.001), positive lymphatic metastasis (pooled OR = 2.43, 95% CI 1.72–3.41, p < 0.001), and distant metastasis (pooled OR = 2.10, 95% CI 1.13–3.89, p < 0.001) in Table 3, 4, 5, 6. This evidence concerns the gene UCA1 and cancer.
