BACKGROUND: Tumor-infiltrating immune cells influence diffuse large B-cell lymphoma (DLBCL) outcomes. Relatively little, however, is known about the significance of peripheral blood immune cell numbers on DLBCL behavior.
PATIENTS AND METHODS: In the present study, 43 patients with newly diagnosed DLBCL had pretreatment multiparameter peripheral blood flow cytometry performed to assess the immune cell numbers. These cell numbers were correlated with the outcomes of progression-free survival (PFS) and overall survival.
RESULTS: After follow-up period of 0.8 to 152 months (median, 73), 25 patients (56%) were still alive. As continuous variables on univariate analysis, the predictors of PFS were patient age and absolute CD4 cell count (ACD4C), with the International Prognostic Index (IPI) marginally significant. Age was also a significant predictor of overall survival, and the IPI and ACD4C were marginally significant (P = .08). The 17 patients with a greater ACD4C (≥ 450/mm3) had better 5-year PFS than the 26 with a low ACD4C (88% vs. 50%; P = .02). Multivariable analysis, including age as a continuous variable, IPI group, and ACD4C of 450/mm3 showed that age and ACD4C were significant for PFS (P = .01 and P = .02, respectively).
CONCLUSION: Our data, although from a small series, suggest that the blood ACD4C might be a predictor of PFS for patients with DLBCL, independent of age and the IPI.
