However, in recent years, it has been found that more than 30% of patients experience relapse within two years after first-line treatment, which is a serious health threat and requires urgent secondary treatment. To reduce the recurrence of DLBCL and improve the survival rate of patients, clinical researchers have long been dedicated to the maintenance treatment of DLBCL patients after first-line treatment, aiming to kill tumor cells and reduce the risk of recurrence through continuous drug administration, thus enabling patients to survive with the tumor for a long time. Several clinical trials are currently underway with rituximab, ibrutinib, lenalidomide, and thalidomide, but safer and more effective maintenance regimens have yet to be identified.\n\nZanubrutinib, a new-generation BTK inhibitor, is the first anti-tumor drug developed locally in China and approved for marketing in the US. Zanubrutinib inhibits the activation of the BCR signaling pathway by specifically binding to cysteine residues at the active site of BTK to form a covalent bond that irreversibly inactivates them, thereby inhibiting BTK and improving the tumor microenvironment, inhibiting malignant proliferation and inducing apoptosis in tumor B cells. Several clinical studies have demonstrated that ibrutinib alone and in combination is no less effective than ibrutinib in the treatment of DLBCL, and has a better safety and tolerability profile.\n\nThis study proposes to use Zanubrutinib for maintenance treatment in DLBCL patients in remission after primary treatment and to evaluate the efficacy and safety of patients to provide new insights into the clinical use of Zanubrutinib.",[37],{"label":38,"type":39,"description":40,"interventionNames":41},"experimental group","EXPERIMENTAL","According to the initial treatment plan of the patients, the patients were divided into R-CHOP and R-chemo groups.
