[Change of Neutrophils/ Lymphocyte Ratio in Patients with DLBCL before and after CHOP or R-CHOP Chemotherapy and Its Effect on Survival of Patients].

OBJECTIVE: To analyze the change of neutrophil/lymphocyte ratio (NLR) in patients with diffuse large B cell lymphoma (DLBCL) patients before and after CHOP or R-CHOP chemotherapy and its effect on survival of patients.

METHODS: Clinical data of 60 patients with DLBCL were collected and were retrospectively analyzed. According to median NLR, 60 patients were divided into the group L in 33 cases (NLR< 2.27) and group H in 27 cases (NLR≥ 2.27). The curative effect and survival rate by using CHOP or R-CHOP after chemotherapy were compared between the two groups.

RESULTS: In the group H, the total effective rate after chemotherapy (55.56%) was significantly lower than that of group L (87.88%), which showed that the difference were statistically significant (P<0.05); the cumulative survival rate of 1,2,3 years in the group H (70.37%, 59.26%, 37.04%) were significantly lower than that in the group L (93.94%, 87.88%, 60.61%) (P<0.05). The NLR≥ 2.27 before chemotherapy was the factor influencing the prognosis of patients with DLBCL (P<0.05).

CONCLUSION: The NLR≥ 2.27 before chemotherapy may be used as a factor influencing the prognosis of patients with DLBCL, and the high NLR may indicate poor clinical efficacy and worse prognosis.
