Abstract:
Objective To explore the expression and clinical significance of sodium borate transporter member 11 of solute carrier family 4 (SLC4A11) and tumor protein P53 (TP53) proteins in gastric cancer (GC).Methods From March 2004 to December 2009,a total of 415 patients with GC,who received operation at Department of General Surgery of Affiliated Hospital of Nantong University,were enrolled.The clinical data and gastric tissues samples of them were collected.At same period,64 patients with non-malignant gastric diseases,who underwent surgery at Department of General Surgery of Affiliated Hospital of Nantong University,were also recruited.The clinical data and gastric precancerous tissues were also collected.The tissues were maken into tissue microarray (TMA).The expression of SLC4A11 and TP53 protein in tissue microarrays was detected by immunohistochemical staining.The relationship between the two proteins and clinicopathological parameters and prognosis of patients were analyzed.Chi square test,and univariate and multivariate analyses were used for statistical analysis.Results The positive rates of protein expression of SLC4A11 and TP53 in GC tissues were 48.19％ (200/415) and 34.94％ (145/415),respectively,which were higher than 17.19％ (11/64) and 6.25％ (4/64) in gastric precancerous lesions,respectively,and the differences were statistically significant (x2 =24.150 and 59.345;both P＜0.01).The results of statistical analysis showed that the expression of SLC4A11 was correlated with human epidermal growth factor receptor 2(Her2) levels,depth of invasion,distant metastasis and TNM staging (x2 =28.056,11.300,8.880,24.943;all P＜0.05).Meanwhile,the expression of TP53 was related with depth of invasion,lymph node metastasis,distant metastasis,TNM staging and preoperative carcinoembryonic antigen (CEA;x2=12.333,7.875,9.347,20.307,10.678;all P＜0.05).The expression of TP53 was significantly positive correlated with SLC4A11 expression (x2 =6.237,P=0.013).The results of univariate analysis showed that SLC4A11,TP53,SLC4A11+/TP53+,Her2,preoperative CEA and cancer antigen 19-9 (CA19-9) levels were correlated with the poor prognosis of GC patients (hazard ratio (HR)=1.947,1.459,1.797,1.419,2.221,1.908;all P＜0.05),while the results of multivariate analysis indicated that positive SLC4A11 and TNM staging were the independent parameters for judging the prognosis of patients with GC (HR =1.954,1.468,both P＜0.05).Conclusions The high expression of SLC4A11 and TP53 is related to the occurrence and development of GC.Combined detection of their changes will contribute to the early diagnosis and prognostic evaluation of patients with GC.
