肝細胞癌切除例106例を対象に, PIVKA-II測定の臨床的意義についてalphafetoprotein (AFP) と比較することにより検討した.術前にPIVKA-IIおよびAFPを測定した症例はそれぞれ106例, 29例で, 術前陽性率はPIVKA-II58.6%, AFP64.2%であった.PIVKAHIIは腫瘍径が5cmをこえると全例陽性であった.腫瘍径2cm以下の小肝細胞癌においては, PIVKA-IIは陽性率37H5%と低率であったが, 陽性の場合, 脈管侵襲または肝内転移を全例に認め, すでに進行癌と認識する必要があった.予後規定因子との関係では, AFP陽性例の49.2%が脈管侵襲陽性であったのに対して, PIVKA-IIは70.6%と有意に高率であった (p<0.01).被膜浸潤についても同様の傾向がみられた.このようにPIVKA-IIは腫瘍進行度, 特に脈管侵襲, 被膜浸潤の有無をよく反映していた.
