The strategies for treating primary hepatocellular carcinoma with portal vein tumor thrombus

Purpose: To further improve the effectiveness and prognosis of primary hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT), the current status of treatment for HCC with PVTT was reviewed. Methods: A Medline search was undertaken to identify articles using the keywords HCC, PVTT and therapy. Additional papers were identified by a manual search of the references from the key articles. Results: PVTT, as a common complication of HCC, was divided into type I similar to IV. The therapeutic approach is mainly composed of five types: surgical resection, regional interventional therapy, radiotherapy, combination therapy, targeted therapy. All of these therapeutic approaches were separately evaluated in detail. Conclusions: For those resectable tumors, the better choice for treatment of HCC with PVTT should be hepatectomy and removal of PVTT. For those unresectable tumors, TACE (especially the super-selective TACE) has been the preferred palliative treatment, the other regional interventional therapy and/or radiotherapy could improve the therapeutic effects. The multidisciplinary treatments may further improve the quality of life and prolong the survival period for the HCC patients associated with PVTT.
