   * Absolute Lymphocyte Count(ALC)≥0.7×10\^9/L;
   * Platelet≥100×10\^9/L；
   * International Normalized Ratio（INR）≤1.5×ULN;
   * Activated Partial Thromboplastin Time（APTT）≤1.5×ULN;
   * Serum Creatinine (Scr)≤1.5mg/dL (or 132.6μmol/L) or Creatinine Clearance≥60mL/min
   * Urinalysis: urine protein less than 2+, or 24-hour urine protein \<1g;
   * Alanine aminotransferase(AST/SGOT) ≤3×ULN;
   * Alanine aminotransferase (ALT/SGPT) ≤3×ULN;
   * Total Bilirubin(TBIL)≤1.5×ULN；
8. Patients must have a washout period ≥ 4 weeks from prior anticancer therapy(ies) to the start of the planned preconditioning regimen, including targeted therapy, chemotherapy, immunotherapy: anti-cytotoxic T lymphocyte-associated antigen 4 (CTLA-4)/anti-PD-1, other monoclonal antibody (mAb), or vaccine Palliative radiation therapy.
9. Patients of childbearing potential or their partners of childbearing potential must be willing to take the appropriate precaution to avoid pregnancy or fathering a child for the duration of the study and practice an approved, highly effective method of birth control during treatment and for 12 months after receiving the last protocol-related therapy.
10. Patients must have no contraindications for surgery or biopsy.
11. Patients (or legally authorized representative) must have the ability to understand the requirements of the study, have provided written informed consent as evidenced by signature on an ICF approved by an Institutional Review Board/Independent Ethics Committee (IRB/IEC), and agree to abide by the study restrictions and return to the site for the required assessments, including the OS Follow-up Period.

Exclusion Criteria:

1. Patients have not recovered from all prior therapy-related adverse events (AEs) to ≤ Grade 1 (per Common Terminology Criteria for Adverse Events \[CTCAE\] v5.0), except for alopecia or vitiligo, prior to Enrollment (tumor resection).
2. Patients who have received an organ allograft or prior cell transfer therapy.
3. Patients with symptomatic and/or untreated brain metastases (of any size and any number).
4. Patients who are on chronic systemic steroid therapy for any reason.
5. Patients who have active medical illness(es) that would pose increased risk for study participation, including: active systemic infections requiring systemic ABX, coagulation disorders, or other active major medical illnesses of the cardiovascular, respiratory, or immune system.
6. Patients with systemic active infection requiring treatment, with positive blood culture or imaging evidence of infection, including active tuberculosis.
7. Patients with hepatic encephalopathy, hepatorenal syndrome, Child-Pugh class B or more severe cirrhosis, or liver failure.
8. Uncontrolled arterial hypertension（SBP≥160mmHg and/or DBP≥100mmHg）or any unstable cardiovascular or cerebrovascular disease in the recent 6 months of consent.
9. Patients who have a left ventricular ejection fraction (LVEF) \< 50% or New York Heart Association (NYHA) functional classification Class 3 or Class 4.
10. Female patients who are pregnant or breastfeeding.
11. Patients who are HIV positive, positive syphilis serological test, positive COVID-19 nucleic acid test, or clinically active hepatitis A, B, and C including virus carriers.
