[摘要] 背景与目的:炎症导致肿瘤的重要性近来引起了学者的高度关注,而C反应蛋白(C reactive protein,CRP)是联系肿瘤和炎症之间的桥梁。本文旨在探讨CRP水平与鼻咽癌临床分期的关系。方法:采用免疫比浊法测定20例健康人群、20例鼻咽良性炎症及68例鼻咽癌不同分期患者的CRP水平,经相关性分析,初步探讨CRP水平与炎症及肿瘤的关系。结果:放疗前鼻咽癌患者的血清CRP水平[(19.8±4.7) mg/L]显著高于健康对照组[(6.2±1.8) mg/L],但显著低于良性炎症组[(45.6±7.9) mg/L,P<0.05];鼻咽癌T4组mg/L]、T2期组[(18.6±8.5) mg/L]和T3期CRP水平[(25.6±3.9) mg/L]均高于T1期组[(17.4±5.8) mg/L]均高于N0期组[(17.6±6.8) mg/L]、组[(15.6±1.8) mg/L],N3期组CRP水平[(28.0±7.1) mg/L]和N2组[(18.6±5.6) mg/L],Ⅳ期组CRP水平[(25.7±5.5) mg/L]均高于ⅠN1组[(21.3±5.1)
期组[(14.2±1.9) mg/L]、Ⅱ期组[(16.1±3.9) mg/L]和Ⅲ期组[(23.0±7.7) mg/L],差异有显著性(P<0.05)。其余各组组间经比较无统计学差异。结论:CRP与鼻咽癌和鼻咽良性炎症的发生有一定的关系,鼻咽癌分期越晚CRP值越高。

[Abstract] Background and purpose:Recent literature has high lighted an important role of inflammation in promoting cancer. CRP (C reactive protein) is a way of building the bridge between inflammation and cancer. We aimed to explore correlations between CRP levels and clinical stages of nasopharyngeal carcinoma(NPC). Methods:We analyzed 108 cases, among which 68 cases were NPC, 20 cases were benign inflammatory diseases of nasopharynx, and another 20 were healthy volunteers as control. We detected the level of CRP using immunoturbidimetry (ITM), q test was calculated by SPSS. Results:The mean concentrations of CRP in NPC [(19.8±4.7) mg/L] were significantly increased compared to those in the control group [(6.2±1.8) mg/L], while they were significantly lower than those in benign inflammatory group [(45.6±7.9) mg/L]. In NPC, The mean concentrations of CRP in T
4 [(25.6±3.9) mg/L] were higher than those in T1 [(17.4±5.8) mg/L], T2 [(18.6±8.5) mg/L] and T3 [(15.6±1.8) mg/L] respectively. The mean concentrations of CRP in N3 [(28.0±7.1) mg/L] were higher than those in N0 [(17.6±6.8) mg/L], N1 [(21.3±5.1) mg/L] and N2 [(18.6±5.6) mg/L] respectively. The mean concentrations of CRP in Ⅳ [(25.7±5.5) mg/L] were higher than those in Ⅰ [(14.2±1.9) mg/L], Ⅱ [(16.1±3.9) mg/L] and Ⅲ [(23.0±7.7) mg/L] respectively (P<0.05). There were no statistic differences between the other groups. Conclusion:The serum CRP level is associated with the occurrence of NPC and benign inflammatory disease of nasopharynx. In NPC, the higher the CRP level is, the more advanced the TNM stage will be.

险程度增加。近年来,人们试图从炎症角度探讨肿瘤的发生发展及治疗。C反应蛋白(C reac-tive protein, CRP)可能是肿瘤和炎症之间的桥
《》梁。多项研究表明是一种炎症相关蛋白,和肿瘤患病风险、临床分期、预后等均相关,在恶性肿瘤中扮演重要角色[1-3]。CRP检测方便,检测方法成熟,因此可望成为肿瘤检测的新指标。
有关CRP和许多肿瘤的联系已见诸多报道,但其和鼻咽癌的联系尚无报道。本研究拟采用免疫比浊法测定20例健康人群、20例良性炎症组及68例鼻咽癌不同分期患者CRP水平,经相关性分析,初步探讨CRP水平与鼻咽癌患者分期的关系。
