CEACAM5 and neoplasm: Multivariate analyses showed that NLR ≥2.15 (HR: 1.421, 95% CI: 1.074–1.881; HR: 1.358, 95% CI: 1.029–1.792), CEA >10μg/L (HR: 1.915, 95% CI: 1.230–2.979; HR: 1.829, 95% CI: 1.178–2.842), tumour size ≥ 5 cm (HR: 1.455, 95% CI: 1.088–1.947; HR: 1.488, 95% CI: 1.111–1.992), multiple tumours (HR: 1.567, 95% CI: 1.146–2.142; HR: 1.479, 95% CI: 1.085–2.018), adjacent organ invasion (HR: 1.770, 95% CI: 1.062–2.951; HR: 1.894, 95% CI: 1.138–3.149), and vascular invasion (HR: 1.861, 95% CI: 1.348–2.568; HR: 1.855, 95% CI: 1.346–2.556) were independent risk factors of OS and tumour recurrence.
