The Safety and Effectiveness of Four Courses of R-CHOP Plus Four Courses of Rituximab Versus Six Courses of R-CHOP Plus Two Courses of Rituximab in the Treatment of Naive, Low-risk, Non-mass Diffuse Large B-cell Lymphoma: a Multi-center, Prospective, Randomized Controlled Study


Diffuse large B cell lymphoma (DLBCL) is the subtype with the highest incidence, accounting for 35.8% of B cell lymphoma. 6 to 8 cycles of R-CHOP regimen is currently the standard first-line regimen for DLBCL, however, the side effects including nausea, vomiting, neutropenia, hair loss, and heart failure can decrease the life quality and are sometimes life threatening. Recently, domestic and foreign scholars have been committed to reduce the dose of chemotherapy and improve the quality of life in low-risk patients. This study uses 4 courses of R-CHOP plus 4 courses of R (4+4 plan) versus 6 courses of R-CHOP plus 2 courses of R (6+2 plan) for the treatment of newly treated, low-risk, non-mass DLBCL patients. The promising result will create a new model for the treatment and improve the life quality of low-risk DLBCL.

Yes No Not Sure

Inclusion Criteria

Pathologically confirmed CD20 positive DLBCL based on 2016 WHO classification who achieved CR after 4 cycles of RCHOP therapy (examined by PET-CT, Deauville score 1-2)
Treatment naïve
Age ≥ 14 or ≤75 years
non-mass (The length of the lesion<7.5cm)
Life expectancy>6 months
Informed consented

Exclusion Criteria

Have received systemic or local treatment including chemotherapy in the past
Have received autologous stem cell transplantation in the past
Past medical history of other malignant tumors, except basal cell carcinoma of the skin and cervical cancer in situ
Accompanied by uncontrolled cardiovascular and cerebrovascular diseases, coagulopathy, connective tissue diseases, severe infectious diseases and other diseases
Primary skin, primary central nervous system lymphoma
Left ventricular ejection fraction ≦50%
Other concurrent and uncontrolled situation which will affect the patient's medical status based on researchers decision
Laboratory test value during screening: (unless it is caused by lymphoma) Neutrophils <1.5 _109/L Platelet <80_109/L Hemoglobin <100g/L ALT or AST is 2 times higher than the upper limit of normal, AKP and bilirubin are 1.5 times higher than the upper limit of normal E. Creatinine level is higher than 1.5 times the upper limit of normal
Psychiatric patients or other patients who are known or suspected to be unable to fully accomplish with the research protocol
Pregnant or lactating women
Patients with positive HbsAg test results need to undergo HBV-DNA test and can be admitted to the group after turning negative. In addition, if the HBsAg test result is negative, but the HBcAb test is positive (regardless of the HBsAb status), HBV-DNA is also required;if the result is positive, patients also need to be treated to become negative before entering the group
Patients living with HIV
Patients with TP53 mutations or those who have not undergone DLBCL hot spot gene screening
