To evaluate the predictive value of ctDNA in response, relapse for liver cancer patients treated with immune checkpoint inhibitors

Full description

In the study, 300 advanced primery liver cancer patients who received immune checkpoint inhibitors at first-line setting (N=200) or second-line setting (N=100) will be recruited. By analyzing the ctDNA and peripheral blood mononuclear cell (PBMC) collected before and after the first cycle of ICI treatment, the dynamic changes of bTMB, ctDNA and the composition of immune cells will be detected. Combined with the tumor markers AFP, DCP and CA19-9, a noninvasive multiparameter model will be developed.

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers
