Routine blood tests: reference ranges are provided below, and final judgment may be made by the investigator considering variations in normal reference ranges across central laboratories: * Absolute neutrophil count (ANC) ≥ 1.0 × 10⁹/L; * Lymphocyte count (LC) ≥ 0.5 × 10⁹/L; * Platelet count (PLT) ≥ 80 × 10⁹/L; * Hemoglobin (Hb) ≥ 90 g/L. 2. Liver function tests: aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤ 2.5 × ULN; total bilirubin (TBIL) ≤ 1.5 × ULN. Criteria may be relaxed under the following conditions: * Confirmed liver metastasis: AST and/or ALT ≤ 5 × ULN; * Confirmed liver or bone metastasis: ALP ≤ 5 × ULN; * Confirmed Gilbert syndrome: total bilirubin (TBIL) ≤ 3.0 mg/dL. 3. Renal function tests: creatinine clearance (CrCL) ≥ 45 mL/min (calculated using the Cockcroft-Gault formula), or serum creatinine (Cr) within normal range; and urine protein (Pro) \< 2+. 4. Coagulation function tests: APTT ≤ 1.5 × ULN, and international normalized ratio (INR) or PT ≤ 1.5 × ULN. 5. Good cardiac function. 6. Good pulmonary function. * 9\. Women of childbearing potential who are not surgically sterilized must agree to use at least one medically accepted contraceptive method (e.g., intrauterine device, oral contraceptives, or condoms) during study treatment and for 1 year after the end of study treatment. Female participants of childbearing potential who are not surgically sterilized must have a negative serum human chorionic gonadotropin (HCG) test within 7 days prior to cell infusion. * 10\. Adverse events resulting from prior therapy have resolved (CTCAE 5.0 ≤ Grade 1) before tumor sampling, or are judged by the investigator and the sponsor's physician to have no impact on this study. * 11\. Participants enrolled due to disease progression must have radiographic documentation of disease progression following the most recent prior therapy before tumor sampling. Exclusion Criteria: * 1\. Patients with spinal cord compression that has not been relieved by surgery and/or radiotherapy shall not be enrolled (treated patients may be enrolled if clinical evidence shows symptom relief for ≥ 1 week prior to surgical sampling). * 2\. Patients with uncontrolled tumor-related pain as judged by the investigator. Participants requiring analgesic therapy must have a stable analgesic regimen at study entry; symptomatic lesions eligible for palliative radiotherapy should have completed treatment prior to study entry. * 3\. Bleeding events occurring within 3 months prior to screening, including but not limited to gastrointestinal bleeding due to gastric fundal or esophageal varices, increased bleeding risk due to portal hypertension, active gastrointestinal bleeding, etc.; or patients assessed by the investigator to be at high risk of major bleeding, including but not limited to tumor encasement or invasion of major blood vessels (i.e., carotid artery, jugular vein, bronchial artery) and/or other high-risk features such as fistula, significant cavitary lesions, history of hemorrhage (≤ 60 days from signing ICF). * 4\. Active arterial/venous thrombotic events occurring within 3 months prior to screening, including but not limited to cerebrovascular accident, deep vein thrombosis, pulmonary embolism, etc. * 5\. Presence of respiratory diseases severely affecting pulmonary function. * 6\. History of clinically significant cardiovascular diseases, including but not limited to: 1. Congestive heart failure (New York Heart Association \[NYHA\] class \> 2); 2. Unstable angina; 3. Myocardial infarction within the past 3 months; 4. Any supraventricular or ventricular arrhythmia requiring treatment or intervention. * 7\. Participants with ≥ 3 untreated central nervous system (CNS) metastases at screening (participants with ≤ 3 CNS metastases, maximum diameter \< 1 cm, no peritumoral edema on brain imaging \[MRI or CT\], and no evidence of progressive CNS disease on brain imaging for at least 3 months after treatment may be enrolled). * 8\. History of autoimmune disease, or active autoimmune disease requiring systemic corticosteroids or immunosuppressive therapy (\> 10 mg/day prednisone or equivalent). * 9\. Presence of refractory or intractable epilepsy, uncontrolled massive pleural effusion, ascites, pericardial effusion, etc., active gastrointestinal bleeding, or contraindications to IL 2 administration. * 10\. Malignancies other than the target indication diagnosed within 5 years prior to screening (excluding adequately treated basal cell or squamous cell skin cancer, radically resected ductal carcinoma in situ of the breast, etc.), unless the investigator determines that the benefits to the participant outweigh the risks. * 11\. Presence of infectious diseases at screening, such as HIV, syphilis, active hepatitis, active pulmonary tuberculosis, active EBV and/or CMV infection. Patients positive for hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) may participate if HBV DNA is below the lower limit of normal (LLN) of the local laboratory. Patients positive for anti-HCV antibody may participate if HCV RNA is below the LLN of the local laboratory. Carriers shall receive antiviral therapy as appropriate and undergo regular quantitative nucleic acid testing during the study. * 12\. Patients with prior allogeneic bone marrow transplantation or solid organ transplantation. * 13\. Administration of anti-angiogenic agents such as VEGF/bevacizumab within 4 weeks prior to tumor sampling. * 14\. Receipt of systemic anti-tumor therapy within 4 weeks prior to lymphodepletion conditioning, except for the following: * Bridging therapy; * For prior nitrosourea or mitomycin C chemotherapy, at least 6 weeks must elapse between the end of chemotherapy and the planned first study drug administration; * For prior small-molecule targeted therapy, at least 5 half-lives of the agent must elapse between the end of treatment and the planned first study drug administration. * 15\. Prior receipt of genetically modified or edited cell therapy products (excluding unmodified/unedited autologous immune cell therapy products administered more than 1 year before cell infusion). * 16\. History of hypersensitivity to any component of the study agents (including but not limited to autologous tumor-infiltrating lymphocytes, cyclophosphamide, fludarabine, interleukin 2, dimethyl sulfoxide \[DMSO\], human serum albumin \[HSA\], dextran 40, antibiotics \[β lactams, gentamicin\]). * 17\. Known psychiatric disorders, alcoholism, drug addiction or substance abuse. * 18\. Prior immune-related adverse events of Grade 3 or higher that did not resolve to CTCAE Grade 1 or lower within 28 days; any disease or condition (any other medical disorder, metabolic dysfunction, physical examination finding or laboratory abnormality) that would reasonably contraindicate the use of the investigational product, interfere with interpretation of study results, or place the participant at high risk of treatment complications. * 19\. Pregnant or lactating women, or women planning to become pregnant, lactate or conceive within 1 year after cell infusion. * 20\. Receipt of other investigational clinical trial drugs within 4 weeks prior to screening, or planning to participate in other investigational clinical trials during the study period. * 21\. Any other conditions deemed inappropriate for enrollment by the investigator.
