title: [Activity of gamma-glutamyltranspeptidase in clear cell carcinomas of the human kidney and renal cortex].
abstract: In 30 operated patients (23 men and 7 women) we determined the activity of GGTP in the tissue of renal clear-cell carcinomas and in their renal cortex. It was found that the enzyme activity was constantly lower in the tumours than in the spared kidney however with a correlation between the enhancement of GGTP activity in the renal cortex and clear-cell carcinomas originating in the tissue of the cortex. In contrast we did not observe a relation between the degree of morphological differentiation of the neoplasms and GGTP activity. The authors discuss the problem in the light of literature data.
