With recent advances in techniques, the efficacy and safety of radiation therapy for PVTT has been improved. The optimization of individualized radiotherapy and multimodality treatment is the future direction of research. In this review, we will investigate the current state and future opportunities of radiation therapy and multimodality treatment for HCC with PVTT.

Downstaging treatment of hepatocellular carcinoma with portal vein tumor thrombus / 临床肝胆病杂志

Hepatocellular carcinoma with portal vein tumor thrombus has a high incidence rate and rapid progression, and there are limited therapies with a poor clinical effect. Although sorafenib is recommended as the sole therapy for such patients in foreign guidelines, studies have shown that some patients may achieve a better outcome via surgical treatment, especially those with tumor thrombus in the first- or second-order branches of the portal vein (type Ⅰ/Ⅱ thrombus according to Cheng’s classification). However in clinical practice, a large proportion of patients cannot undergo radical resection due to extensive lesions, or there may be a high possibility of residual tumor thrombus after surgery due to the presence of tumor thrombus in the main portal vein (type Ⅲ according to Cheng’s classification), and therefore, downstaging resection is needed to improve prognosis. Studies have shown that with the help of palliative therapies including neoadjuvant three-dimensional conformal radiotherapy, (90)Y-loaded microsphere radioembolization, and hepatic arterial infusion chemotherapy, some patients may achieve regression or disappearance of portal vein tumor thrombus, tumor shrinkage, and disappearance of satellite lesions, which helps to achieve tumor downstaging, increase surgical resection rate, and prolong survival time. Multidisciplinary therapy is of vital importance in improving downstaging resection rate in patients with hepatocellular carcinoma and portal vein tumor thrombus.

Risk factor analysis of recurrent hepatocellular carcinoma with portal vein tumor thrombus / 中国实用外科杂志

OBJECTIVE: To investigate the effect of clinicopathological factors on the recurrent hepatocellular carcinoma(HCC)with portal vein tumor thrombus(PVTT)after radical resection.METHODS: The data of patients with HCC who underwent radical resection between January 2000 and December 2014 in Affiliated Hospital of Qingdao University were analyzed retrospectively.Clinical and pathological data from first resection to the recurrence of HCC with PVTT were extracted in the form of data tables.All patients were divided into PVTT group and non PVTT group according to the occurence of PVTT at time of HCC recurrence,and the risk factors of PVTT formation were analyzed.Risk factors influencing the formation time,from radical resection to HCC recurrence,were analyzed in recurrent HCC patients with PVTT.RESULTS: Univariate analysis results showed that patients having HCC with multiple tumors,no tumor capsule,and Child-pugh B grade had a high proportion of PVTT when HCC recurred.The results of logistic regression analysis showed that multiple tumors,no tumor capsule,and Childpugh B grade were independent risk factors for PVTT formation after radical resection of HCCA predictive model was established on the basis of the three risk factors(1 point for each factor).ROC curve showed the total model score has certain predictive value.The area under the curve was 0.662(P=0.003,95% CI:0.557-0.766),cut-off value was 0.5 points,Youden index was 0.302(sensitivity=60.0%,specificity=70.2%).The higher the model score,the shorter the tumor-free survival time(P=0.007),and the higher the incidence of PVTT recurrence(P=0.001).The results of Kaplan-Meier(log-rank test)and multivariate analysis of Cox regression model showed that lower differentiation of HCC was an independent risk factor influencing the time from radical resection to HCC recurrence with PVTT(P=0.000). CONCLUSION: Patients with multiple tumor foci,no tumor capsule and Child grade B grade liver cancer are more likely to recur with PVTT after RO operation.And among them,the low differentiation of liver cancer grows faster.A closer follow-up or preventive treatment of patients with high-risk factors may improve prognosis.

Establishment and application of a multidisciplinary team approach for hepatocellular carcinoma with portal vein tumor thrombus / 第二军医大学学报

Portal vein tumor thrombus (PVTT) is one of the most important clinical characteristics of advanced hepatocellular carcinoma (HCC). The incidence of PVTT has been reported to be 44%-66.2% in patients with HCC who were firstly diagnosed, and 80%-90% were patients with advanced HCC. Once PVTT occurs in patients with HCC, the prognosis is very poor, and the natural survival time is only 2.7-4 months. The current treatment strategy for HCC patients with PVTT remains controversial. Sorafenib is recommended as the only treatment option in Europe and America; and a variety of treatment methods, including surgical treatment, transcatheter arterial chemoembolization, radiotherapy, and systemic chemotherapy, were advocated in Asia. At present, there is no consensus on diagnosis and treatment of HCC with PVTT. Our team has established a multidisciplinary team approach for diagnosis and treatment of HCC with PVTT, and has carried out systematic research and application. This article reviews the molecular mechanism of PVTT in patients with HCC, clinical diagnosis and treatment of PVTT, and the establishment and application of a multidisciplinary team approach.
