OBJECTIVE: To study the relationship between the expression of SATB2 in colonic adenocarcinoma and clinicopathological factors, and its role in the identification of ovarian digestive system metastatic adenocarcinoma.
METHODS: Immunohistochemistry was used to analyze the expression of SATB2 in 130 cases of colon adenocarcinoma, 46 cases of gastric adenocarcinoma, 47 cases of pancreatic ductal adenocarcinoma, 22 cases of cholangiocarcinoma, 53 cases of ovarian mucinous adenocarcinoma, and 38 cases of ovarian metastasis of colorectal carcinoma. Data was analyzed using SPSS 16.0 statistical software.
RESULTS: The positive expression rate of SATB2 in 130 cases of colon adenocarcinoma was 73.85% (96/130). The expression rate of SATB2 was significantly higher in well -moderately differentiated colon adenocarcinoma than in poorly differentiated adenocarcinoma (p<0.05); the expression rate was significantly higher in cases without tumor deposits than in cases with tumor deposits (p<0.05). The positive expression rate of SATB2 in ovarian metastases of colorectal adenocarcinoma was 81.58% (31/38). No positive expression of SATB2 was observed in other cancers.
CONCLUSION: Loss of expression of SATB2 is associated with poor differentiation of primary colon cancer and the formation of tumor deposits. SATB2 provides an ideal diagnostic marker for clinical surgeons to choose the right treatment plan.
