中文摘要:
      目的:探讨信号转导和转录活化因子3 (signal transducer and activator of transcription 3,STAT3),Bcl-2 和基质金属蛋白酶 (matrix metalloproteinase,MMP-2) 在结肠直肠腺瘤和结肠直肠腺癌中的表达,研究其与结肠直肠腺癌临床病理特征和预后的关 系,阐明三者在结肠直肠腺癌的浸润转移、判断预后中的作用。方法:选取我院2011 年9 月至2013 年8 月结直肠黏膜慢性炎100 例,结肠直肠腺瘤100 例,结肠直肠腺癌200 例石蜡标本,其中结肠直肠腺癌伴远处转移70 例,无远处转移130 例,采用Envison 二步法检测STAT3,Bcl-2和MMP-2 在三种组织中的表达。结果:STAT3,Bcl-2 和MMP-2在结肠直肠腺瘤、腺癌的阳性表达率明 显高于在结直肠黏膜慢性炎中的阳性表达率,差异有统计学意义(P<0.05);STAT3、MMP-2在结肠直肠腺癌伴有远处转移病例的 阳性表达率明显高于没有远处转移的病例,差异有统计学意义(P<0.05);Bcl-2在结肠直肠腺癌伴有远处转移病例的阳性表达率与 没有远处转移病例的阳性表达率差异无统计学意义(P>0.05)。结论:STAT3,Bcl-2 和MMP-2均与结肠直肠癌的发生,发展有关; STAT3 和MMP-2与结肠直肠癌的远处转移相关,可能提示患者预后不良,可作为评价结肠直肠腺癌复发与转移、不良生存预后 的候选临床标志。
英文摘要:
      Objective:To investigate the expressions of signal transducer and activator of transcription factor3 (STAT3), Bcl-2, and matrix metalloproteinase 2 (MMP-2) in colorectal adenomas and adenocarcinomas, and to explore the relationship with the colorectal clinicopathological features and prognosis of intestinal adenocarcinomas, and their roles in the invasion, metastasis and the prognosis of a colorectal cancer.Methods:The samples were selected from our hospital from September 2011 to August 2013, including 100 cases of paraffin-coded colorectal mucosas with chronic inflammation, 100 cases of paraffincoded colorectal adenoma and 200 cases of paraffin-coded colorectal adenocarcinomas (70 cases with metastasis and 130 cases without distant metastasis). Envison two-step method was used to detect the expressions of STAT3, Bcl-2, and MMP-2 in each sample.Results:The expression of STAT3, Bcl-2, and MMP-2 in colorectal adenomas and adenocarcinomas were significantly higher than those in colorectal mucosas with chronic inflammation (P<0. 05). The expressions of STAT3 and MMP-2 in colorectal adenocarcinomas with distant metastasis were significantly higher than those without distant metastasis (P<0.05). No significant difference of Bcl-2 expression was observed in colorectal adenocarcinomas with and without distant metastasis (P>0.05).Conclusion:STAT3, Bcl-2 and MMP-2 were associated with the occurrence and development of colorectal carcinoma. STAT3 was associated with the distant metastasis of colorectal carcinoma and might indicate a poor prognosis. STAT3 might be used as a candidate clinical sign for the recurrence, metastasis, andpoor survival prognosisof colorectal adenocarcinoma.
