摘要
目的观察肿瘤内C反应蛋白(CRP)在肾细胞癌中的表达,探讨其在肾癌发生发展中的作用。方法应用免疫组织化学法检测40例肾癌患者手术切除的癌组织及20例癌旁组织石蜡切片中的CRP表达。结果CRP在肾细胞癌组织中的阳性表达率为100%(40/40),其中强阳性率为22.50%(9/40),而正常肾组织的强阳性表达率为0(0/20),两者差异有统计学意义(P〈0.01)。CRP的表达与不同组织学分级、TNM分期和有无转移有关(P〈0.05),与性别、年龄及组织学分类无明显相关(P〉0.05)。结论检测肿瘤内CRP有助于判断肾细胞癌侵袭性和估计预后。
Objective To observe the expression and significance of intratumor C-reactive protein (CRP) in renal cell carcinoma (RCC). Methods Immunohistochemistry was used to detect the CRP ex pression in 40 eases of RCC and 20 eases of normal kidney tissue. Results The positive rate of CRP ex pression in RCC was 100% (strongly positve expression rate of 22. 50% ) , and that was 0 in the normal kidney tissue was 0 (0/20) with the difference being statistically significant (P 〈0. 01 ). The expression of CRP in RCC was not related to the gender, age and histological classification ( P 〉 0. 05 ) , but to differ ent histological grade, TNM stage and metastases of RCC. Conclusion Intratumor CRP testing can help determine tumor invasiveness and prodict the prognosis of RCC.
