Summary

The investigators will first use our previously collected serum samples and surgical/biopsied tissues from HBV-related HCC patients undergoing radiotherapy. The consistency of junctional clones by Capture NGS needs to be tested between both pre- and post-RT serums, and serial changes in copy numbers of vh-DNA by ddPCR are quantified in the representative cases. The same junction clones from pre-post-RT serums and surgical tissues will be confirmed and the copy number changes of vh-DNA be correlated with RT response and disease-control status.

The investigators plan to identify HBV integrations by Capture NGS and quantify the specific vh-DNA by ddPCR as personalized biomarkers from the same-patient serum samples. The investigators will further correlate clinical response and recurrence/metastasis with serial changes of vh-DNA copy numbers. The investigators have been prospectively collecting plasma samples from HBV-related HCC patients before/after RT, at 1, 4, 7 months, and at recurrence/metastasis. The investigators plan to confirm the viable role of pre-/post-RT changes of plasma vh-DNA copies of the same junction clone in post-RT response and prognosis. Moreover, The investigators will explore the recurrent/metastatic tumors arising from the original or a de novo one by identifying their clonality with HBV integration patterns. The true value of this novel HBV chimera vh-DNA will be revealed. The results will also support the consolidative use of personalized vh-DNA for earlier evaluating treatment response after RT, for post-RT disease monitoring, and for differentiating clonality at recurrence to design future clinical trial on combinational treatment.
