ABSTRACT
Objective@#To investigate the clinical value of combined detection of serum miR-378 and miR-21 in gastric cancer (GC).@*Methods@#Eighty-seven patients with GC and 78 patients with colorectal cancer(CRC) from National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences were selected, 83 individuals undergoing healthy physical examination were selected as the healthy controls. The levels of serum miR-378 and miR-21 were detected by quantitative real-time PCR (RT-qPCR) (result data were transformed as log2 for analysis).@*Results@#Relative expression levels of miR-378 in the serum were -1.24, -3.25 and -2.73 in healthy controls, GC and CRC patients, respectively. Compared with the healthy controls, the levels of serum miR-378 were significantly decreased in GC and CRC patients (both P<0.05). Relative expression levels of miR-21 in the serum were 0.11, 2.34 and 2.47 in healthy controls, GC and CRC patients, respectively. Compared with the healthy controls, the levels of serum miR-21 were significantly up-regulated in GC and CRC patients (both P<0.05). Moreover, the serum level of miR-378 in GC patients was inversely associated with tumor clinical stage (P<0.05). However, the level of miR-21 showed no significant differences among patients with different clinical and pathological characteristics (all P>0.05). The area under the receiver operating characteristic curve (AUC), sensitivity and specificity of miRNA-378 to diagnose GC was 0.770, 82.0% and 66.0%, respectively, and were 0.900, 85.0%, and 88.0% of miR-21, respectively. The AUC, sensitivity and specificity of combined detection of serum miR-378 and miR-21 to diagnose GC were 0.930, 92.0% and 87.0%, respectively, while the AUC of combined detection of serum CEA and CA-199 was 0.767, the AUC of combined all of the four factors was 0.946.@*Conclusion@#The combined detection of serum miR-378 and miR-21 have a certain effect on diagnosis of GC.
