Among cancer types represented by at least two cohorts, high B7H3 expression was linked to poor OS in neuroblastoma (HR = 2.29, 95% CI [1.54–3.42]), colorectal cancer (HR = 1.30, 95% CI [1.03–1.64]), hepatocellular carcinoma (HR = 1.82, 95% CI [1.20–2.75]), and gallbladder cancer (HR = 4.29, 95% CI [2.42–7.60]). This evidence concerns the gene CD276 and colorectal cancer.
