عنوان انگلیسی Evaluation of Immunohistochemical Expression of Survivin and its Correlation with qRT-PCR Results as a Useful Diagnostic Marker in Gastric Cancer
چکیده انگلیسی مقاله Background: Today, survivin is known as one of the most specific cancer proteins; provide unique and practical study opportunities. Clinical value of survivin in gastric cancer (GC) is not yet appointed. To establish the expression level of survivin and its diagnosis value in Iranian patients with GC, we evaluated the association of survivin expression with clinicopathologic factors. Methods: Overall, 60 matched-normal controls with 60 GC samples including 30 cases with evidence of metastasis at time of our study and 30 cases without evidence of metastasis were recruited, in Tehran, Iran during 2008 to 2018. Survivin expression was evaluated by quantitative Real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry (IHC) study. Results: Increased expression of survivin at mRNA and protein levels was found in 86.7% and 71.6% of cases, respectively. Evidence indicated a significant difference in survivin mRNA expression level between tumor and non-tumoral (marginal) tissues (P<0.001). The difference in expression of survivin mRNA was not significant between metastatic and non-metastatic tumor tissues (P=0.171). Positive immunoreactivity of survivin was observed to be predominantly in the nucleus of tumor cells. A significant difference in survivin protein expression was detected between tumor and non-tumoral tissues (P<0.001) and between metastatic and non-metastatic tumor tissues (P<0.001). There was no significant association between survivin mRNA expression and clinicopathological variables. However, survivin protein expression was significantly correlated with perineural involvement (P<0.018). Conclusion: This data could be supportive of using survivin as a useful diagnostic marker in GC. Although, more research is needed in this area.
