ABSTRACT
OBJECTIVE@#To explore the relationship between Treg cells level in peripheral blood and prognosis of patients with diffuse large B-cell lymphoma (DLBCL).@*METHODS@#The percentage and absolute value of Treg cells in peripheral blood of DLBCL patients were detected by flow lytometry, and their correlation to prognosis was analyzed by survival analysis. The absolute count of Treg cells was detected by using maximally selected Log-rank statistic, and it was used as cutoff point to distinguish difference survival. The new group of Treg based on cutoff point was combined with age, sex, pathological subtype, risk stratification, treatment plan, and other indicators to include in the single factor survival analysis of Kaplan-Meier. Finally, the COX proportional risk model was used to verify the effect of the above indicators on progression-free survival.@*RESULTS@#The absolute count of Treg cells in DLBCL patients was significantly lower in the disease progressed group than those in the remission group. The cutoff point of absolute value of the Treg cell was 19 cells /μl. The absolute count of Treg cells was an independent prognostic factor of the risk stratification.@*CONCLUSION@#At the beginning of diagnosis, the reduction of the absolute count of Treg cells in peripheral blood of DLBCL patients show a poor prognosis.
