The contents of 15 trace elements in the sera of 30 liver cancer patients and 30 healthy adults were assayed by ICP-AES method. The data obtained were analysed by routine statistical tests, multi-variate discrimination analysis, multi-variate stepwise regression analysis and non-linear mapping algorithm. The results showed that the contents of copper, vanadium, cadmium, stannum, cobalt, nickel in liver cancer patients were significantly higher than those in healthy adults. The serum trace element spectrum of liver cancer patients was different from that of healthy adults. Hence, the liver cancer patients could be differentiated from healthy adults by serum trace element spectrum.
采用电感耦合等离子体发射光谱法（ICP - AES）测定30例肝癌患者和30例健康成年人血清中15种微量元素的含量。运用常规统计检验、多变量判别分析、多变量逐步回归分析及非线性映射算法对所得数据进行分析。结果显示，肝癌患者血清中铜、钒、镉、锡、钴、镍的含量显著高于健康成年人。肝癌患者的血清微量元素谱与健康成年人不同。因此，可通过血清微量元素谱鉴别肝癌患者与健康成年人。
