Correlation between P-selectin, thrombopoietin and severity of glioma / 中国医师进修杂志

ABSTRACT

Objective:To analyze the expression of P-selectin and thrombopoietin (TPO) in patients with glioma, and explore their correlation with severity of disease.Methods:One hundred and six patients with glioma who were treated in the Third People's Hospital of Dalian City from June 2017 to June 2019 were selected as the observation group, and 50 physical examination person in the same period were selected as the healthy control group. The clinic data of patients in two groups were analyzed.Results:The serum P-selectin and TPO levels in the observation group were significantly higher than those in the healthy control group (62.35 ± 16.71) μg/L vs. (25.42 ± 9.18) μg/L, (12.64 ± 3.26) μg/L vs. (6.93 ± 1.77) μg/L ( P<0.01). In patients with different severity of glioma, serum P-selectin and TPO levels in the high-grade group were significantly higher than those in the low-level group (65.14 ± 17.19) μg/L vs. (53.71 ± 15.26) μg/L, (14.57 ± 3.38) μg/L vs. (9.04 ± 1.97) μg/L ( P<0.01). Serum P-selectin and TPO levels in patients with glioma after treatment were significantly lower than those before treatment (57.28 ± 16.22) μg/L vs. (62.35 ± 16.71) μg/L, (10.85 ± 2.97) μg/L vs. (12.64 ± 3.26) μg/L ( P<0.01). Spearman correlation analysis result showed that there was a significant positive correlation between serum P-selectin, TPO levels and WHO classification in patients with glioma ( r = 0.417 and 0.361, P<0.05). The results of receiver operating characteristic (ROC) curve analysis showed that the area under curve (AUC) of serum P-selectin in the diagnosis of glioma was 0.859 (95% CI 0.794 to 0.910, P<0.01), the sensitivity was 90.00%, and the specificity was 74.53%. The ROC curve analysis result showed that the AUC of serum TPO in the diagnosis of glioma was 0.720 (95% CI 0.643 to 0.789, P<0.01), the sensitivity was 69.81%, and the specificity was 72.00%. Conclusions:Serum P-selectin and TPO are abnormally expressed in glioma patients, and their level changes are related to the severity of the disease.
