ABSTRACT

Objective:

To investigate the prognostic significance of D-dimer level in patients with diffuse large B-cell lymphoma (DLBCL).

Methods:

The clinical data of 70 newly diagnosed DLBCL patients who were admitted to Tianjin People's Hospital from January 2015 to June 2019 were retrospectively analyzed. The optimal cut-off value of D-dimer for survival was determined according to the receiver operating characteristic (ROC) curve, and the patients were grouped. The differences of coagulation related indexes and clinicopathological features between patients with different D-dimer levels were compared. Kaplan-Meier method was used for univariate analysis of overall survival (OS), and Cox regression model was used for multivariate analysis of OS.

Results:

According to ROC curve, the best cut-off value of D-dimer for survival was 0.75 mg/L. The proportion of patients with different clinical staging, international prognostic index score, lactate dehydrogenase level had statistically significant differences between the D-dimer ≥0.75 mg/L group (36 cases) and <0.75 mg/L group (34 cases) (all P < 0.05). The prothrombin time of D-dimer ≥ 0.75 mg/L group and < 0.75 mg/L group were (13.5±0.9) s and (13.0±0.8) s, respectively, and the activated partial thromboplastin time were (37±5) s and (34±6) s, respectively,and the differences were statistically significant (all P < 0.05). Univariate analysis showed that the 5-year OS rates of DLBCL patients with Ann Arbor stage Ⅲ-Ⅳ, international prognostic index score > 2, lactate dehydrogenase level > 240 U/L, B symptoms, D-dimer level ≥0.75 mg/L were decreased (all P < 0.05). Multivariate Cox regression analysis showed that D-dimer ≥0.75 mg/L was an independent risk factor for OS of DLBCL patients ( HR=0.368, 95% CI 0.144-0.944, P= 0.038).

Conclusion:

The level of D-dimer can be used as a clinical indicator to judge the prognosis of DLBCL patients, and the prognosis of patients with high D-dimer level is poor.
