Abstract

Background/purpose: Patients with hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) have an extremely poor prognosis and relatively few treatment options. Method: During a consensus meeting, experts met to examine the published data for HCC treatment strategies in patients with PVTT. Results: Many treatment guidelines consider the presence of PVTT a contraindication to partial hepatectomy or liver transplantation. Transarterial chemoembolization (TACE) is associated with an increased risk of ischemic necrosis of liver and of treatment-related death in patients with PVTT, and is, therefore, limited to a select group of patients with good hepatic function and adequate collateral circulation around the occluded portal vein. Systemic sorafenib results in survival benefit in patients regardless of the presence of PVTT. However, side effects are common, and there are no effects on time-to-symptom progression or quality of life. Transarterial radioembolization (TARE) with yttrium-90 microspheres is emerging as a valuable strategy. A wider range of patients with PVTT are suitable for this procedure compared to TACE. TARE is as effective as TACE in HCC and has quality-of-life advantages. Conclusion: In patients with HCC with PVTT, medical evidence suggests that TARE is a good choice of treatment.

    • "Literature shows that this curative effect is superior to TACE and that it is safer for PVTT patients, with an effective rate up to 28%- 50% and median survival time up to 3.2-10.4 months [70]. Lewandowski et al [71] conducted a retrospective analysis of 86 HCC patients with PVTT undergoing either TARE with Y 90 microspheres or TACE. "
    [Show abstract] [Hide abstract] ABSTRACT: Hepatocellular carcinoma (HCC) complicated by portal vein tumor thrombus (PVTT) is associated with poor prognosis, early recurrence of HCC, and limited treatment options. Current guidelines do not have standardized diagnostic and treatment modalities, thus creating a need for a multidisciplinary treatment model for standardization of the treatment. Eastern Hepatobiliary Surgical Hospital (China) convened two working parties of experts from all the departments, to consolidate the current evidence, prevailing vision for the future, and experience of the practicing clinicians engaged in HCC management, so as to develop a consensus for PVTT diagnosis and treatment according to the GRADE system. Based on the quality of the existing evidence and the strength of recommendations, the consensus statements were categorized into 3 evidence levels (A/B/C) and 5 classes (I/II/IIa/IIb/III).The panel discussed and provided clarity on the management and research options in the field of HCC with PVTT. In addition, the panel also assessed the quality of the cited studies and assigned grades to the recommendation statements. Among the group of experts, there was excellent agreement with regard to effective diagnosis and treatment of HCC with PVTT. The recommendations of this consensus will provide guidance to physicians and clinical researchers on the effective management of HCC with PVTT.

    • "Other investigators have used magnetic resonance imaging to show similar results [28]. Therefore, we believe that sorafenib should be administered only after recanalization of major PVTT by other treatments [9]. The optimal treatment regimen for patients with unresectable HCC and PVTT remains to be established. "

Methods Ninety-seven patients were retrospectively reviewed. Forty patients were enrolled by the Kanagawa Liver Study Group and received sorafenib, and 57 consecutive patients received RT in our hospital. Overall survival was compared between the two groups with PVTT by propensity score (PS) analysis. Factors associated with survival were evaluated by multivariate analysis. Results The median treatment period with sorafenib was 45 days, while the median total radiation dose was 50 Gy. The Child-Pugh class and the level of invasion into hepatic large vessels were significantly more advanced in the RT group than in the sorafenib group. Median survival did not differ significantly between the sorafenib group (4.3 months) and the RT group (5.9 months; P = 0.115). After PS matching (n = 28 per group), better survival was noted in the RT group than in the sorafenib group (median survival, 10.9 vs. 4.8 months; P = 0.025). A Cox model showed that des-γ-carboxy prothrombin <1000 mAU/mL at enrollment and RT were significant independent predictors of survival in the PS model (P = 0.024, HR, 0.508; 95% CI, 0.282 to 0.915; and P = 0.007, HR, 0.434; 95% CI, 0.235 to 0.779; respectively). Conclusions RT is a better first-line therapy than sorafenib in patients who have advanced unresectable HCC with PVTT.
