L. Xiao et al., INAA OF ELEMENTAL CONTENTS IN FINGERNAILS OF ESOPHAGEAL CANCER-PATIENTS, Journal of radioanalytical and nuclear chemistry, 195(1), 1995, pp. 43-49
Fingernails of pathologically diagnosed normal people, light esophagea
l epitheliosis patients, severe esophageal epitheliosis patients and e
sophageal cancer patients were irradiated and their elemental contents
were determined by INAA. Multivariate statistical treatment of Ca, Cl
, K, Mg, Se and Zn data shows that esophageal cancer patients are dist
inguishable from non-cancer patients. The accuracy computed by neural
networks is greater than 80%.
