Summary
Brief summary (as posted)
Due to the biological characteristics and liver anatomical characteristics of liver cancer, liver cancer cells easily invade the vascular system, especially the portal venous system, forming portal vein tumor thrombus (PVTT) , and its incidence is reported to be 44.0% \~ 62.2%. Once PVTT occurs in patients with liver cancer, the disease develops rapidly, and intrahepatic and extrahepatic metastasis, portal hypertension, jaundice, and abdominal effusion can occur in a short time with an average survival time of 2.7 months. PVTT is one of the major adverse factors for the prognosis of liver cancer and occupies an important weight influence in the clinical staging system of liver cancer. In some hepatocellular carcinoma (HCC) patients with PVTT and selective resectability, surgery versus non-surgery can lead to better survival of patients. A retrospective analysis showed that neoadjuvant radiotherapy can reduce the extent of invasion of PVTT and improve postoperative survival in some HCC patients. Another prospective study showed that neoadjuvant radiotherapy could significantly improve the overall survival of resectable liver cancer with PVTT, and neoadjuvant radiotherapy could improve the 2-year survival of patients from 9.4% to 27.4% 27.4%, with an effective response of 20.7%. This study is a prospective, single-center, single-arm study to assess the efficacy and safety of neoadjuvant therapy with tislelizumab combined with IMRT for resectable liver cancer with PVTT.
