目的检测子宫颈癌患者放疗前后血清铜、锌的变化，检测子宫颈癌患者与正常人血清铜、锌水平的比较。材料与方法采用三电极直流等离子原子发射光电直读光谱仪法检测。结果子宫颈鳞癌患者血清铜（ＳＣｕ）、铜锌比值（Ｃｕ／Ｚｎ）显著高于正常对照组（Ｐ＜０．００１），Ⅲ期患者又显著高于Ⅱ期患者（Ｐ＜０．００１）；放疗后癌灶完全消退者（ＣＤ）ＳＣｕ、Ｃｕ／Ｚｎ明显下降（Ｐ＜０．０１）；部分消退者（ＰＤ）二值仍处于高水平。结论：ＳＣｕ和Ｃｕ／Ｚｎ可以检测放疗疗效，估计预后，有一定临床意义。
Objective To detect the changes of serum copper and zinc in patients with cervical cancer before and after radiotherapy and to compare the levels of serum copper and zinc in patients with cervical cancer and normal people. Materials and Methods Three-electrode direct current plasma atomic emission spectrometer was used to detect. Results The levels of SCu and Cu / Zn in patients with cervical squamous cell carcinoma were significantly higher than those in normal controls (P <0.001), and those in patients with stage Ⅲ were significantly higher than those in patients with stage Ⅱ (P <0.001) ). The SCu and Cu / Zn of the complete remission (CD) SCs decreased significantly after radiotherapy (P <0.01). The partial remission (PD) values of the two samples were still at a high level. Conclusion: SCu and Cu / Zn can detect radiotherapy efficacy, prognosis, a certain clinical significance.
