Eligibility Criteria

2 Years - 70 Years (Child, Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • 1. Diagnosed as relapsed or refractory lymphoma; 2. Tumor cells express CD7 (express CD7 by flow cytometry or immunohistochemistry); 3. The expected survival period is greater than 12 weeks; 4. KPS or Lansky score ≥60; 11 5. Age 2-70 years old; 6. HGB≥70g/L (can be transfused); 7. Indoor blood oxygen saturation> 90%; 8. Total bilirubin does not exceed 3 times the upper limit of normal value, and AST and ALT do not exceed 5 times the upper limit of normal value; 9. The subject or guardian understands and signs the informed consent form;

Exclusion Criteria:

  • 1. One of the following cardiac criteria: atrial fibrillation; myocardial infarction within the past 12 months; prolonged QT synthesis Syndrome or secondary QT prolongation is at the discretion of the investigator. Echocardiography LVSF<30% or LVEF< 50%; clinically significant pericardial effusion; cardiac insufficiency NYHA (New York Heart Association) III or IV (the absence of this symptom confirmed by echocardiography within 12 months after treatment); 2. There is active GVHD; 3. Have a history of severe pulmonary dysfunction diseases; 4. Merge other malignant tumors in advanced stage; 5. Combined with severe infection or persistent infection and cannot be effectively controlled; 6. Combined with severe autoimmune disease or congenital immunodeficiency; 7. Active hepatitis (hepatitis B virus deoxyribonucleic acid [HBVDNA] or hepatitis C virus ribonucleic acid [HCVRNA] test positive); 8. Human immunodeficiency virus (HIV) infection or syphilis infection or HTLV infection; 9. There is a history of severe allergies to biological products (including antibiotics); 10. Clinically significant viral infection, or uncontrollable viral reactivation, including EBV (Epstein-Barr virus), CMV (cytomegalovirus), ADV (adenovirus), BKV, HHV(human herpesvirus)-6; 11. There are central nervous system disorders, such as uncontrolled epilepsy, cerebrovascular ischemia/hemorrhage, dementia, Cerebellar diseases, etc.; 12. Female patients are pregnant and lactating, or have a pregnancy plan within 12 months; 13. Circumstances that the researcher believes may increase the risk of the subject or interfere with the results of the test.
