For RFS, greater tumor differentiation (HR (95% CI): 2.840 (1.110–7.264); P = 0.029), greater vascular invasion (HR (95% CI): 2.106 (1.186–3.426); P = 0.010), the absence of tumor encapsulation (HR (95% CI) for tumor encapsulation: 0.303 (0.179–0.511); P < 0.001) and higher CCT7 expression (HR (95% CI): 1.695 (1.012–2.839); P = 0.045) were both risk factors and independent risk factors for poorer RFS (Table 4). The gene discussed is CCT7; the disease is neoplasm.
