haptoglobin (HP) and transferrin (TF) were measured in 94 nasopharyngeal carcinoma and 65 cancer of larynx. Statistical evalution was made with stepwise discriminant analysis

and the discriminant functions were obtained. The effectiveness of allocation were examined on every one of all patients in the original data

Our results suggested

with the discriminant function equation consisting of serum PA

α1-AT

α1-AGP

HP and TF concentrations we could best separate the patients sufferng from nasopharyngeal or laryngeal carcinoma from the normal; the effective rate of discriminant was 87.36% and 88% for nasopharyngeal carcinoma from normal and laryngeal carcin-oma from normal respectively. However using discriminant function equation

composed of serum sialic acid

PA and α1-AT

we could also discriminate nasopharyngeal or laryngeal carcinoma with recurrence from the one with non-recurrence

the effective rate of discriminant was 93.1% and 80% for nasopharyngeal carcinoma and cancer of larynx respectively
