As well known there exist complex interaction between the trace elements, and the trace elements and other substances, so the trace element research must be involved to the com-prehensive effect of multifactors, other than single element. We determined the contents of fifteen trace elements in serum from thirty patients with liver cancer and thirty healthy adults by ICP-AES analysis. The obtained data were analysed statistically by not only routine statistical test bat also multi-variate discrimination analysis, multi-variate stepwise regression and non-linear mapping algorithm. It is hoped that it can provide some valuable informations for investigation on relationship betwecn trace elements and cancer.展开更多
