Immunotherapy has become the major breakthrough and the most promising treatment, with the host of development of tumor biology, molecular biology and immunology. ROBO1 is a potential target and spectacular paradigm in the diagnosis and treatment of solid tumors. This study is for evaluation of the safety and efficacy of ROBO1 CAR-NK/T cell immunotherapy for malignant tumors.

7. Signed informed consent
8. Women of child-bearing age must have evidence of negative pregnancy test and be willing to practice birth control after 2 weeks following the cell transfusion
