Eligibility Criteria
Inclusion
- Histopathologically confirmed CD20+ diffuse large B-cell lymphoma (DLBCL).
- The lesions were confined to the central nervous system, including the brain, spinal cord, eyes and meninges.
- Through physical examination, imaging examination (including CT, MRI, PET-CT, etc.) and bone marrow puncture examination, it was confirmed that no parts other than the central nervous system were involved.
- Patients who have not previously received chemotherapy or radiotherapy (except those with dexamethasone less than 10mg/ day (or equivalent dose) and duration less than 5 days).
- Aged between 18 and 75 (inclusive).
- Eastern Cooperative Oncology Group performance status 0 to 3.
- Measurable disease was defined as at least ≥1.0cm in short-diameter by enhanced MRI.
- Life expectancy of ≥ 3 months (in the opinion of the investigator).
- Participants must be able to understand and be willing to sign a written informed consent document.
- Participants can follow up on schedule, communicate well with the investigator and complete the trial according to the trial regulations.
- Women of reproductive potential must agree to use highly effective methods of birth control during the period of therapy and for 6 months after the last dose of the study drug. Men who are sexually active must agree to use highly effective contraception during the period of therapy and for 6 months after the last dose.
Exclusion
- Have systemic lymphoma disease.
- Previous systemic or local treatment such as chemotherapy and/or radiotherapy and/or hematopoietic stem cell transplantation.
- Previous or concurrent history of other malignant tumors requiring active therapy.
- Chronic or currently active infectious diseases requiring systemic antibiotic, antifungal, or antiviral treatment (except EBV infections).
- Accompanied by uncontrolled cardiovascular and cerebrovascular diseases, bleeding diseases, thrombotic diseases, connective tissue diseases and other diseases.
- Patients with other uncontrolled diseases that the researchers deemed unsuitable for inclusion.
- Laboratory test values at screening (unless due to lymphoma) : White blood cell count \< 3.5×109/L, neutrophils \<1.5×109/L, platelets \<80×109/L, hemoglobin \<100g/L, ALT or AST 2.5 times higher than the upper limit of normal, bilirubin 1.5 times higher than the upper limit of normal, creatinine level 1.5 times higher than the upper limit of normal.
- Presence of active hepatitis B virus(HBV) infection (HBsAg positive and HBV-DNA≥ 104), hepatitis C virus(HCV) infection, acquired and congenital immunodeficiency diseases include but not limited to HIV. HbsAg positive patients need to check HBV-DNA \< 10\^4 to be enrolled. In addition, if HBsAg is negative but HBcAb is positive (regardless of HBsAb status), HBV-DNA testing is also required, and HBV-DNA results \< 10\^4 are required to be enrolled and continue treatment and monitoring of HBV-DNA. HCV antibody positive patients need to check HCV-RNA quantitative DNA \< 10\^3 to be enrolled.
- Pregnant or lactating women.
- Those with a history of drug use or abuse were asked.
- Patients with mental illness or other patients known or suspected to be unable to fully comply with the study protocol.
- Known allergy to the investigational drug or its related ingredients.
- Patients are unable to swallow capsules or suffer from diseases or conditions that severely affect gastrointestinal function, such as malabsorption syndrome, removal of the stomach or small intestine, or complete intestinal obstruction.
- Patients who cannot withstand enhanced MRI.
- Participants considered unsuitable for this clinical trial due to various other reasons.
