In addition, the PFS local was significantly reduced in patients with older age (CI, 0.999–1.052; HR, 1.026; p = 0.056), larger target tumor diameter (CI, 1.033–1.023; HR, 1.013; p = 0.014), and particularly CRLM (CI, 1.202–3.095; HR, 1.929; p = 0.006). The multivariate Cox regression model confirmed the predictive value of the patients’ age (CI, 1.001–1.053; HR, 1.026; p = 0.044) for PFS local ; it also revealed a strong trend for target tumor diameter (CI, 1.000–1.020; HR, 1.010; p = 0.057) and CRLM (CI, 0.963–3.254; HR, 1.770; p = 0.066), respectively.
