• 4) Previous progression or intolerance after failure to target, immunization, or conventional therapy (including TKI, ICI, chemotherapy, VEGF monoclonal antibody, or ICI combined with TKI/VEGF monoclonal antibody/chemotherapy)

• 5) 2 weeks after the end of previous systemic therapy = the first dose of this study, and the treatment-related AEs recovered to NCI-CTCAE = Grade 1 (except for alopecia)

• 6) Child-Pugh liver function rating within 7 days prior to the first dose of the study drug: A grade and good B grade (= 7 points)

Intervention

Drug:
• Rituximab+PD-1 or PD-L1 inhibitors+targeted therapy
Rituximab: Dissolve 375mg/m2 in 0.9% sodium chloride injection, dilute to a concentration of 1 mg/mL of rituximab, intravenous infusion every 3 weeks until tumor progression or intolerable toxic reactions occur. The recommended initial infusion rate is 50mg/h; After the initial 60 minutes, an increase of 50mg/h can be made every 30 minutes until the maximum speed is 400mg/h. The starting rate of rituximab infusion in the future can be 100mg/h, increasing by 100mg/h every 30 minutes until the maximum rate is 400mg/h.
