鼻咽癌血清新蝶呤水平检测及其意义

Measurement of serum neopterin levels in patients with nasopharyngeal carcinoma and its significance

目的 :探讨血清新蝶呤与鼻咽癌的关系及临床意义。方法 :采用 EL ISA竞争法检测 5 4例初治鼻咽低分化鳞癌 (鼻咽癌组 )治疗前、后及 32例健康成人 (对照组 )的血清新蝶呤水平。结果 :鼻咽癌组新蝶呤浓度明显高于对照组 (P <0 .0 1)。各 TNM分期之间新蝶呤水平无差异 (P >0 .0 5 )。无淋巴结转移者血清新蝶呤浓度低于有淋巴结转移者 (P <0 .0 5 )。治疗后新蝶呤水平比治疗前明显降低 (P <0 .0 1) ,但仍比对照组高 (P <0 .0 1) ;治疗后 6个月病灶全消者新蝶呤水平仍维持较低水平而病灶部分残留者复又上升 (P <0 .0 1)。结论 :鼻咽癌病理发生过程中可能存在着巨噬细胞介导的细胞免疫过激或免疫应答异常 ;血清新蝶呤水平动态观察可作为鼻咽癌病情评估和疗效监测的一项客观指标。

Objective:To evaluate the relationship between serum neopterin levels and nasopharyngeal carcinoma and its clinical significance. Method:The serum neopterin levels were determined in 54 patients with nasopharyngeal carcinoma (NPC group) and 32 healthy adults (normal group) by ELISA. Result:The serum neopterin levels in NPC group were significantly higher than that of in normal group (P< 0.001 ). The serum neopterin levels in UICC TNM stages were undifferentiated (P> 0.05 ). The serum neopterin levels in patients with no lymph node metastasis were lower than that of in lymph node metastasis (P< 0.05 ). The serum neopterin levels decreased significantly after disappearance of tumor and its lymph node treated by radiotherapy (P< 0.01 ). Conclusion:Cellular immunity mediated by macrophages might be involved in the pathologenesis of nasopharyngeal carcinoma and the measurement of the serum neopterin may be a useful objective index to evaluate cellular immunological functions and curative effects.
