摘要

目的:研究Notch1和Smad4的表达与大肠癌临床病理的关系

探讨二者在大肠癌演变中的作用。方法:采用免疫组化方法检测51例大肠癌标本中Notch1和Smad4的表达情况。结果:（1）Notch1的表达明显高于正常组织的表达（P<0.05）

大肠癌组织中Smad4的表达明显低于正常组织（P<0.05）;（2）Notch1表达与年龄、性别、Dukes分期、淋巴结转移无关（P>0.05）

但与肿瘤的大体类型、组织分级有关（P<0.05）;（3）Smad4表达与年龄、性别、大体类型无关（P>0.05）

但与肿瘤的Dukes分期、淋巴结转移、组织分级有关（P<0.05）;（4）Notch1、Smad4联合表达与肿瘤的组织分级有关（P<0.05）

与其他临床病理学特性无关（P>0.05）。结论:Notch1的高表达和Smad4的低表达与大肠癌的发展

生物学行为和预后可能有关

可作为重要的生物学标志。

Abstract

Objective: To observe the expression of Notch1 and Smad4in colorectal carcinoma and their clinical significance. Methods: Immunohistochemistry staining was used to detect the expression of Notch1 and Smad4 in 51cases of colorectal carcinoma. Results:(1) The expression of Notch1 in colorectal carcinoma was higher than that in the normal tissue(P<0.05).The expression of Smad4 in colorectal carcinoma was lower than that in the normal tissue(P<0.05)(.2)The expression of Notch1 in colorectal carcinoma was not correlated to age and sex of patients

Dukes stage and lymph node of metastasis of colorectal carcinoma(P>0.05)

except histological grading and pathological types of patients(P<0.05).(3)The expression of Smad4 in colorectal carcinoma was not correlated to age and sex of patients

histological grading of colorectal carcinoma(P>0.05)

except Dukes stage

lymph node of metastasis and pathological types of patients (P<0.05).(4)The combined check on the expression ofNotch1and Smad4 in colorectal carcinoma was correlated to histological grading

of patients(P<0.05). Conclusion: Notch1 and Smad4 may be associated with the carcinogenesis

biological behaviors and prognosis of colorectal cancer. The two factors may be used as important biological markers for colorectal cancer.
