Abstract:
Objective:To investigate the expression and clinical significance of serum response factor (SRF) and myosin heavy chain 9 (MYH9) in esophageal squamous cell carcinoma(ESCC).Methods:The clinical data of 113 patients with esophageal squamous cell carcinoma treated in Tangshan people′s Hospital from January 2014 to December 2016 were retrospectively analyzed.Immunohistochemical staining was used to detect the expression of SRF and MYH9 in esophageal squamous cell carcinoma and corresponding adjacent tissues, and the correlation between the differential expression of SRF and MYH9 and clinicopathological features was analyzed.Results:Immunohistochemical staining showed that the positive expression rate of SRF in esophageal squamous cell carcinoma was 42.48% (48/113), which was significantly higher than that of 6.25% (2/32) in adjacent tissues (χ 2=14.487, P<0.05). The positive expression rate of MYH9 was 57.52% (65/113), which was significantly higher than that of 25.00% (8/32) in adjacent tissues (χ 2=10.551, P<0.05). The expression levels of SRF and MYH9 were closely related to the differentiation, lymph node metastasis and TMN stage of ESCC (all P<0.05). The positive expression of SRF had a correlation with positive expression of MYH9( r=0.521, P<0.05). The median survival time of SRF and MYH9 double negative expression group, SRF and MYH9 single positive expression group, SRF and MYH9 double positive expression group were 30, 20 and 12 months respectively.There were significant differences between the double negative, single positive expression groups and double positive expression groups (χ 2 values were 43.855, 17.799, all P<0.001), but there was no significant difference between the double negative and single positive expression groups (χ 2=2.787, P=0.095). Conclusion:SRF and MYH9 may be one of potential targets for diagnosis and treatment of esophagus cancer.
