Tumour responses
Tumour responses are shown in Table 2. Of all the included patients, 1 achieved a complete response (CR) (1.4%), 14 achieved a partial response (PR) (20.0%), and 36 patients had a stable disease (SD) (51.4%), resulting in an objective response rate (ORR) of 21.4% and a disease control rate (DCR) of 72.9%. The subgroup analysis revealed that ORRs in patients with low and high baseline HBV DNA levels were 22.9% and 18.2%, respectively (Fisher’s exact test, P = 0.761), while the DCRs were 75.0% and 68.2%, respectively (χ² = 0.355;P = 0.552).
