2. Metastatic pancreatic cancer with progression after second-line or higher treatment, metastatic gastric cancer with progression after third-line or higher treatment, or metastatic pancreatic or gastric cancer patients who cannot tolerate standard treatment regimens.
3. Able to provide fresh tumor tissue specimens for organoid culture, including: ascites, pleural effusion, tumor biopsy tissues, tumor surgical specimens, etc.
4. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score of 0-2.
5. Adequate organ function, including the following:
* Bone marrow: Absolute neutrophil count (ANC) in peripheral blood ≥ 1.5 x 10\^9/L, platelets ≥ 100 x 10\^9/L, hemoglobin ≥ 80 g/L.
* Liver: Total bilirubin ≤ 1.5 times the upper limit of normal (ULN), aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT) ≤ 3 times ULN. If liver metastases are present, aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT) ≤ 5 times ULN.

You may not be if
1. Any unstable systemic disease (including systemic active infections requiring treatment, liver disease, kidney disease, or metabolic diseases, acute cerebral infarction or cerebral hemorrhage, etc.) that, in the investigator's judgment, may impair patient safety or the patient's ability to complete the study due to severe comorbidities.
2. Significant cardiovascular events: Congestive heart failure \> NYHA class 2; unstable angina, active coronary artery disease (CAD) (myocardial infarction more than 1 year before the study is allowed); severe arrhythmias requiring treatment (use of beta-blockers or digoxin is allowed) or uncontrolled hypertension, etc.
3. Significant history of neurological or psychiatric disorders, including epilepsy, dementia, etc.
4. Pregnant or breastfeeding women; those of childbearing potential who are unwilling or unable to use effective contraception.
