Abstract:
Objective To explore serum long stranded noncoding RNA (lncRNA) transcript 1 (PCAT-1) expression level of patients with multiple myeloma (MM) and clinical value.Methods 72 cases of patients with MM treated in the Second People's Hospital of Zhaoqing City were selected as the study objects,and 60 cases of normal subjects undergoing physical examination in the same period were as the control group.Serum lncRNA PCAT-1 expression was detected by RT-PCR method.The relationship between lncRNA PCAT 1 expression and clinical pathological parameters,treatment effect was analyzed,and 5 years survival was analyzed by using Kaplan-Meier,and survival difference was detected by using Log-Rank method.Results Serum PCAT-1mRNA expression in MM group (2.65 ± 0.64) was significantly higher than that in the control group (1.06 ± 0.23,t=18.276,P=0.000).There were no significant differences in sex,clinical stage and pathological types of hemoglobin,plasma cells,platelets,albumin,β2-MG and CRP between PCAT 1 mRNA high expression group and low expression group (x2 =0.001 ～ 3.345,all P ＞ 0.05).Ca2+ ≥ 10 mg/dl in the PCAT-1 high expression group (57.14％) was significantly higher than that in the low expression group (27.27％,x2 =5.229,P=0.022).There was no significant difference in treatment effect between PCAT-1 mRNA high expression group and low expression group (88.64 ％ vs 75.00％,x2 =2.291,P=0.130).PFS and OS expression in PCAT-1 high expression group were lower than that in the low expression group (x2 =7.269,P =0.007;x2 =9.190,P =0.002).COX risk regression multiple factor analysis showed that age and PCAT-1mRNA expression were independent prognostic factors influencing patients (OR =3.275,P =0.025,95％CI:2.691～3.761;OR=2.136,P=0.046,95％CI:2.034～2.685).Conclusion LncRNA PCAT-1 is highly expressed in serum of patients with multiple myeloma,and correlated with the prognosis of patients.
