1. Choose appropriate patients with advanced pancreatic cancer or other cancers, with written consent for this study;
2. Perform biopsy to determine the expression of Mesothelin of the tumors by western blotting or IHC;
3. Collect blood from the patients and isolate mononuclear cells, activate the T cells and transfect the T cells with Mesothelin targeting CAR, amplify the transfected T cells as needed, test the quality and killing activity of the CAR-T cells and then transfer them back the patients via systemic or local injections, and follow up closely to collect related results as required;
4. To enhance the killing capability, cotreatment the patients with PD1/PDL1/CTLA4 antibodies may be applied;
5. Evaluate the clinical results as needed.
