Abstract:
Objective:To explore the effect of ICE regimen (ifosfamide, carboplatin, VP16) combined with methotrexate on the clinical efficacy and expression of miR-451a and miR-15a in patients with diffuse large B cell lymphoma (DLBCL).Methods:A total of 56 patients with DLBCL in the Third Hospital of Changsha from March 2013 to may 2018 were prospectively selected and randomly divided into observation group and control group, 28 cases in each group. The control group was treated with ICE regimen, and the observation group was treated with ICE regimen combined with methotrexate. The tumor control rate, toxic and side effects, the expression of miR-451a and miR-15a, immune function (CD3 +, CD4 +, CD8 +, CD4 +/CD8 +), serum tumor markers [β 2 microglobulin (β 2-MG), carbohydrate antigen 125 (CA125), and lactate dehydrogenase (LDH)] levels were compared before and after treatment between the two groups, follow-up for 6 to 12 months was used to calculate the survival rate of the two groups. Results:The tumor control rate in the observation group (92.86%) was higher than that in the control group (71.43%) ( P<0.05); After treatment, the miR-15a decreased and miR-451a increased in the two groups, and the miR-15a in the observation group was lower than that in the control group, while miR-451a was higher than that in the control group ( P<0.05); After treatment, the CD3 +, CD4 +, CD4 +/CD8 + of the two groups were lower than before treatment, and CD8 + was higher than before treatment ( P<0.05), but there was no significant difference between the two groups ( P>0.05); After treatment, the serum CA125, LDH, and β 2-MG in the two groups were lower than before treatment, and the above indexes in the observation group were lower than those in the control group ( P<0.05); There was no significant difference between the two groups in the incidence of side effects and the survival rates of 6, 9 and 12 months after treatment ( P>0.05). Conclusions:ICE regimen combined with methotrexate in the treatment of DLBCL can further improve the therapeutic effect and reduce the serum tumor marker levels by regulating the expression of miR-451a and miR-15a, with less toxic side effects and less immune damage, and high safety.
