PULSAR Radiotherapy Combined With Immunotherapy for High-Risk Advanced Liver Cancer
The goal of this clinical trial is to learn if adding PULSAR, a personalized adaptive stereotactic radiotherapy, to standard immunotherapy can control cancer longer in adults with high-risk advanced hepatocellular carcinoma (liver cancer). It will also learn about the safety of this combination. The main questions it aims to answer are:
* What percentage of participants are alive without cancer progression 12 months after starting PULSAR?
* What medical problems do participants have after PULSAR with immunotherapy?
There is no comparison group. Results will be compared with published results
