Abstract:
Objective To investigate the expressions of signal transducer and activator of transcription factor 3 (STAT3),Bcl-2,and matrix metalloproteinase 2 (MMP2) in colorectal adenomas and adenocarcinomas,and the relationship of those factors with the colorectal clinicopathological features and prognosis of intestinal adenocarcinomas,and explore their roles in invasion,metastasis,and prognosis of a colorectal cancer.Methods The samples were selected from Dongyang City People's Hospital from January 2011 to January 2012,including 50 cases of paraffin-coded colorectal mucosas with chronic inflammation,50 cases of paraffincoded colorectal adenomas,and 100 cases of paraffin-coded colorectal adenocarcinomas (35 cases with metastasis and 65 cases without distant metastasis).Envison two method was used to detect the expressions of STAT3,Bcl-2,and MMP2 in each sample.Results The expressions of STAT3,Bcl-2,and MMP2 in colorectal adenomas and adenocarcinomas were significantly higher than those in colorectal mucosas with chronic inflammation (P < 0.05).The expressions of STAT3 and MMP2 in colorectal adenocarcinomas with distant metastasis were significantly higher than that those without distant metastasis (P < 0.05).The expression of BCL-2 had no significant difference between colorectal adenocarcinomas with and without distant metastasis (P > 0.05).Conclusions STAT3,Bcl-2 and MMP2 were associated with occurrence and development of colorectal carcinoma.STAT3 was associated with distant metastasis of colorectal carcinoma and might indicate a poor prognosis.STAT3 might be used as a candidate clinical sign for recurrence,metastasis,and poor survival prognosis of colorectal adenocarcinoma.
