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.

RECRUITINGProgression of disease within 24 months
Progression of disease within 24 months was defined as the rate of disease progression or relapse, using 2014 Lugano criteria, or death from any cause, whichever occurred first.
Time frame: Baseline up to data cut-off (up to approximately 24 months)
Overall response rate
Percentage of participants with overall response examined by PET-CT was determined on the basis of investigator assessments according to 2014 Lugano criteria
Time frame: t the end of Cycle 8 (each cycle is 21 days)
Overall survival
Overall survival was defined as the time from the date of diagnosis to the date of death from any cause. Reported is the percentage of participants with event. of disease progression or relapse, using 2014 Lugano criteria,or death from any cause, whichever occurred first.
Time frame: Baseline up to data cut-off (up to approximately 2 years)
Number of Participants With Treatment-Related Adverse Events as Assessed by CTCAE v4.0
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events
Time frame: Up to 30 days after completion of study treatment
