Levels of gamma-glutamyltranspeptidase and total, alpha 2 and alpha 1-alkaline phosphatase versus dissemination pattern and survival time were studied in patients with stage III and IV tumors of various sites. No significant changes in the activity of the said enzymes were registered in cases of single hepatic metastasis and metastasis-free liver. A slight increase in the enzymes' activity was observed in patients with pronounced liver involvement within months 10-4 before death. That was followed by a sharp and marked (3-4 times normal) rise in the levels during months 4-3. Changes in enzyme activity within the terminal 12 months were described with the aid of polynoms on the basis of regression analysis. A correlation between liver mass and degree of rise in serum enzymes levels was established.
