Inclusion criteria: 1. Signed written informed consent prior to the implementation of any trial-related procedures; 2. Male or female, age =18; 3. It is confirmed by pathological examination as metastatic, but the malignant tumor at the primary site cannot be determined after detailed examination and evaluation; 4. The patient has not received any anti-tumor therapy in the past, including but not limited to surgery, radiotherapy, chemotherapy, immunotherapy, targeted therapy, etc.; 5. ECOG score 0-1; 6. For adequate organ function, subjects must meet the following laboratory criteria: 1) In the past 14 days without the use of granulocyte colony-stimulating factor, the absolute value of neutrophil (ANC) was =1.2x109/L. 2) Platelet =75×109/L. 3) Hemoglobin =9g/dL in the case of no blood transfusion or use of erythropoietin in the past 7 days; 4) Total bilirubin =1.5× upper limit of normal (ULN); 5) Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) are =2.5×ULN 6) Serum creatinine =1.5×ULN and creatinine clearance (calculated by Cockcroft-Gault formula) =50 ml/min; 7) Good coagulation function, defined as International standardized ratio (INR) or prothrombin time (PT) =1.5 times ULN; 8) Normal thyroid function, defined as thyroid stimulating hormone (TSH) within the normal range.If baseline TSH is outside the normal range, subjects with total T3 (or FT3) and FT4 within the normal range can also be enrolled; 9) The myocardial enzyme profile is within the normal range (if the researchers comprehensively judge that the simple laboratory abnormality is not clinically significant, it is also allowed to be included) 7. For female subjects of reproductive age, a urine or serum pregnancy test should be performed negative within 3 days prior to receiving the first study drug administration (day 1 of cycle 1).If the urine pregnancy test results cannot be confirmed as negative, a blood pregnancy test is requested.Women of non-reproductive age were defined as at least one year after menopause or having undergone surgical sterilization or hysterectomy; 8. If there is a risk of conception, all subjects (male or female) are required to use contraception with an annual failure rate of less than 1% for the entire duration of treatment up to 120 days after the last study drug administration (or 180 days after the last chemotherapy drug administration).
Exclusion criteria
Exclusion criteria: 1. Is currently participating in an interventional clinical study treatment, or has received another investigational drug or used investigational devices in the 4 weeks prior to initial dosing; 2.

Pregnant or lactating women; 12. Other situations deemed unsuitable for inclusion by the researcher.
