血管内皮生长因子在大肠癌中的表达及其与病理特征的关系探讨

目的 探讨血管内皮生长因子（VEGF）在大肠癌中的表达与病理特征的关系。方法 对99例大肠癌标本进行免疫组织化学染色（SP法），采用单克隆抗体VEGF进行标记。结果 VEGF阳性率：结肠癌51．16％（22／43），直肠癌67-86％（38／56）；高中分化腺癌组62．50％（45／72），其他组55．56％（15／27）；浸肌层组42．86％（12／28），浸浆膜组67．61％（48／71）；有转移组72．00％（36／50），无转移组48．99％（24／49）。VEGF的表达与大肠癌的发生部位、组织学分型无明显关系，与大肠癌浸润深度及淋巴结转移明显相关。结论 VEGF可作为判断大肠癌复发及预后的一个重要指标。

The relationship between expression of VEGF in colorectal cancer and pathological factors

Objective To explore the correlation between expression of VEGF in colorectal cancer and pathological factors.Methods The expression of VEGF in 99 cases with colorectal cancer was examined by immunohistochemical staining.Results It showed that the expression of VEGF in colorectal cancer was correlated with depth of invasion and lymph node metastasis and was not correlated with tumor region,and histologic type.The frequency of positive cases in patients with lymph node metastasis was significantly higher than that in patients without lymph node metastasis(P<0.05).Conclusion VEGF might be a recurrence and prognostic indicator in patients with colorectal cancer.It is very useful for patients with colorectal cancer in higher expression of VEGF adopting adjuvant chemotherapy and radiotherapy.
