SBRT With DIBH for HCC After TACE and Lipiodol Marking
- Conditions
- Hepatocellular Carcinoma
- Registration Number
- NCT05021250
- Brief Summary
Stereotactic Body Radiation Therapy (SBRT) for hepatocellular carcinoma (HCC) with radical dose achieved similar results with radiofrequency ablation (RF) and radical surgery, according to previous studies. For tumors near great blood vessels or with a diameter more than 2cm, SBRT performs even better than RF. In current clinical practice of SBRT for small HCC, registration is achieved by planting metal markers near the tumor, which has several disadvantages: 1. the operation is invasive, increase the risk of bleeding in patients with cirrhosis; 2. the operation is of no therapeutic value; 3. metal markers can only be planted outside the tumor to avoid transplantation, which compromises the accuracy of registration via CBCT. This study aims to adopt a new method of registration, transcatheter arterial chemoembolization (TACE) and lipiodol marking, to analyze the recognition and clarity of lipiodol on CBCT images, set-up errors and treatment efficacy. Therefore to provide data to support TACE and lipiodol marking over metal marker planting.

- Primary Outcome Measures
Name Time Method Recognition of lipiodol marking During the radiotherapy Judged by 2 technicians and 1 physician on CBCT images. High recognition is concluded when all three consider it easily registered. Moderate recognition is concluded when two consider it easily registered. Poor recognition is concluded when one or none consider it easily registered.
ORR 6 months after radiotherapy Objective response rate
- Secondary Outcome Measures
Name Time Method LCR 12 months and 24 months after radiotherapy Local control rate
Completion rate of treatment model 1 months after TACE Including the success rate of lipiodol deposition at 1 months after TACE and completion of SBRT
PFS 12 months and 24 months after radiotherapy Progress free survival
Frequency of AE up to 24 months Frequency of treatment associated adverse events
