Sorafenib for the treatment of hepatocellular carcinoma with portal vein tumour thrombosis: a systematic review of comparative studies.

ABSTRACT: Sorafenib is the first-line treatment of choice for advanced hepatocellular carcinoma (HCC). However, the benefits of sorafenib in HCC patients with portal vein tumour thrombosis (PVTT) remain uncertain. Until now, a total of eight comparative studies have been identified for this systematic review. Four retrospective studies showed that hepatic arterial infusion chemotherapy, hepatic resection, and three-dimensional conformal radiotherapy might be superior to sorafenib in improving the overall survival. Two ongoing randomised controlled trials (RCTs) will compare the outcomes of transarterial chemoembolisation or radioembolisation with those of sorafenib for the treatment of HCC with PVTT. In addition, two completed RCTs found that additional use of cryotherapy or radiofrequency ablation could prolong the survival of patients receiving sorafenib. In conclusion, the clinical efficacy of sorafenib in HCC patients with PVTT has been widely challenged by other interventions. However, further well-designed RCTs are necessary to confirm the findings of retrospective analyses. Cryotherapy or radiofrequency ablation may be considered as an adjunctive therapy in such patients, if sorafenib is prescribed.

Project description:BackgroundHepatic portal vein collateral circulation plays an important role in maintaining the perfusion of hepatic portal vein. However, at present, there is little research on collateral circulation of hepatic portal vein. Our study aims to analysis the imaging types and clinical value of hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) invading and completely blocking different branches of portal vein, secondary to hepatic portal vein collateral circulation.MethodsThis study retrospectively analyzed Hepatocellular carcinoma (HCC) with PVTT diagnosed with enhanced CT examination of the upper abdomen in our hospital from May 2020 to October 2021.The inclusion criteria for patients were the following: (I) ultimately diagnosed with HCC, (II) accompanied by complete obstruction of the main portal vein or left/right branches, and (III) with collateral circulation of the hepatic portal vein established. All images were postprocessed by multiplanar reconstruction (MPR), maximum intensity projection (MIP), and other reconstruction techniques to obtain images of the abnormal portal vein system and the collateral vessels running toward the hepatic portal veins. Three physicians jointly judged the imaging anatomical classification of each collateral vessel. The qualitative variables were compared by chi-squared test.ResultsA total of 125 hepatic portal vein collateral vessels were observed in MPR and MIP reconstruction images of 71 patients with portal vein cancer thrombosis with established hepatic portal vein collateral circulation. Common hepatic collateral branches in patients with PVTT mainly include the biliary collateral branch, gastric collateral branch, mesenteric collateral branch, accessory portal vein system and the splenic branch. The incidence rate was respectively 77.5%, 36.6%, 32.4%, 28.2%, 1.41%.ConclusionsThe correct understanding of the imaging anatomical classification of the collateral vessels of the hepatic portal vein can provide clinicians with more information for diagnosis and treatment planning.
