donafenib combined with tace as adjuvant therapy of patients with hepatocellular carcinoma

Conditions: Hepatocellular Carcinoma

Summary: the investigators design a phase iib clinical study to explore the efficacy and safety of donafenib combined with tace as adjuvant therapy of patients with hepatocellular carcinoma at a high risk of recurrence after radical resection.

this trial is a single-arm, non-randomized and single-center clinical study of targeted therapy combined tace in patients with hepatocellular carcinoma at a high risk of recurrence after radical resection.it is estimated that 30 patients who met the study criteria will be enrolled in peking union medical college hospital(pumch) and treated with donafenib and tace. the investigators will follow up and collect subjects' data monthly to evaluate the efficacy and safety of treatment, including overall survival and time to progression.

if the patient has previously used traditional chinese medicine with anti-tumor indications, it must be more than 4 weeks after the completion of treatment and before the medication in this study, and the adverse events caused by treatment have not recovered to ≤ ctcae level 1; 7. received other adjuvant therapy (except antiviral therapy), including adjuvant local therapy; 8. there were tumor thrombi in the main portal vein and primary branches, inferior vena cava, hepatic vein or bile duct, lymph node invasion or extrahepatic metastasis before operation; 9. 5 years of suffering from other malignancies, unless the patient has received the possibility of curative treatment and there is no evidence of the disease within 5 years, the time requirement (i.e. 5 years) does not apply to successful basal cell carcinoma, cutaneous squamous cell carcinoma, superficial bladder cancer, cervical carcinoma in situ or other orthotopic cancer. 10. previous history of severe mental illness; 11. suffering from diseases affecting the absorption, distribution, metabolism or clearance of the study drug (such as severe vomiting, chronic diarrhea, intestinal obstruction, absorption disorder, etc.); 12. taking drugs that may prolong qtc and / or induce tip twist transition ventricular tachycardia (tdp) or drugs that affect drug metabolism at the same time; 13. the patient has known or suspected allergy to tyrosine kinase inhibitor (tki) drugs, or is allergic to the excipients of the study drugs; 14. there are uncontrollable hepatic encephalopathy, hepatorenal syndrome, ascites, pleural effusion or pericardial effusion; 15. have active bleeding or abnormal coagulation function, have bleeding tendency or are receiving thrombolytic, anticoagulant or antiplatelet therapy; 16. have a history of gastrointestinal hemorrhage or have a clear tendency of gastrointestinal bleeding in the past 4 weeks (e.g. local active ulcer lesions, fecal occult blood + + or more, gastroscopy should be performed if continuous fecal occult blood +, or other conditions that may cause gastrointestinal bleeding determined by the researcher (e.g. severe gastric fundus / esophageal varices); 17. gastrointestinal perforation, abdominal fistula or abdominal abscess occurred in the past 6 months; 18. thrombosis or thromboembolism events occurred in the past 6 months, such as stroke and / or transient ischemic attack, deep vein thrombosis, pulmonary embolism, etc; 19. uncontrolled cardiovascular disease judged by the researcher. including but not limited to the following situations: 1. acute myocardial infarction in the past 6 months; 2. severe / unstable angina pectoris or coronary artery bypass grafting;
