The patient voluntarily participated in the study, had good compliance, was able to cooperate with the experimental requirements to complete the observation and follow-up, and signed the informed consent; 2. At least 18 years old; ECOG 0-2; Expected survival =3 months; 3. Histologically or cytologically confirmed advanced or metastatic solid tumors; 4. Patients with advanced solid tumors with CR, PR or SD=6 months after first-line treatment including PD-1 inhibitor; Or secondary drug resistance that develops disease progression after a clear response to first-line therapy containing PD-1 inhibitors as assessed by the investigator; 5. The subject has at least one measurable lesion: at least one diameter line that can be accurately measured (recorded as the maximum diameter), the minimum length of which is as follows: CT scan 10 mm (the thickness of CT scan is not more than 5mm) clinical routine examination instrument 10 mm (tumor lesions that cannot be accurately measured by diameter instruments should be recorded as unmeasurable) Chest X-ray 20 mm malignant lymph nodes: Pathological enlargement and measurable, the CT scan diameter of a single lymph node must be =15 mm (CT scan thickness is recommended to be no more than 5 mm). At baseline and follow-up, only short diameters were measured and followed. 6. There were no contraindications or allergic reactions to the drugs used in this study. 7.

Women of reproductive age should agree to use contraceptives (such as Iuds, birth control pills or condoms) during the study period and for six months after the study; Men should agree to use contraception during the study period and for six months after the end of the study period;
