[Blood lipase activity in cancer patients]

Blood plasma lipoprotein lipase level was measured in lung and stomach cancer patients before surgery and during postoperative period. A drop in the enzyme level was observed, particularly, in patients at stage IV. Postoperative infusion and drug therapy was followed by increase in the enzyme activity in stage III disease whereas at stage IV, only a tendency of lipoprotein lipase to rise was observed. Deterioration in patient condition led to a sharp decrease in the enzyme activity.
