Hydrolytic enzymes in colorectal cancer.

Activities of sulphatases A/B, sulphatase C, beta glucuronidase, acid and alkaline phosphatase were measured in 38 cases of colorectal cancer. A wide variation in the levels of individual enzymes was observed, suggesting that certain patients might benefit from therapy with tailor made enzyme activated anti-tumour agent. The activity of sulphatase C was correlated with the other lour, but the enzyme profile could not predict the evofution of the disease.
