Locoregional treatment while on the waiting list for liver transplantation (Ltx) for hepatocellular carcinoma (HCC) has been shown to improve survival. However, the effect of treatment type has not been investigated. We investigate the effect of locoregional treatment type on survival after Ltx for HCC. We investigated patients registered in the European Liver Transplant Registry database using multivariate Cox regression survival analysis. Information on locoregional therapy was registered for 4978 of 23 124 patients and was associated with improved overall survival [hazard ratio (HR) 0.84 (0.73-0.96)] and HCC-specific survival [HR 0.76 (0.59-0.98)]. Radiofrequency ablation (RFA) was the one monotherapy associated with improved overall survival [HR 0.51 (0.40-0.65)]. In addition, the combination of RFA and transarterial chemoembolization also improved survival [HR 0.74 (0.55-0.99)]. Adjusting for factors related to prognosis, disease severity, and tumor aggressiveness, RFA was highly beneficial for overall and HCC-specific survival. The effect may represent a selection of patients with favorable tumor biology; however, the treatment may be effective per se by halting tumor progression. Clinicaltrials.gov number: NCT02995096.
Vascular invasion as a prognostic indicator remains superior to criteria based on size and number of nodules. With continuously improving imaging studies, microvascular invasion may be used for selecting patients for transplantation in the future.
Our results demonstrate that preemptive therapy is a safe and an effective strategy for the control of CMV infection in solid-organ transplant recipients at high risk for CMV infection. This is the first study that reports a therapeutic effect of the acquisition of CMV-specific immune response during preemptive treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
