[Biological behavior of prostatic carcinoma. I. Histochemical studies of enzyme activities in primary tumors].

Enzyme histochemical investigations of prostatic carcinoma were done by means of reference enzymes of different metabolic pathways. The results of these investigations show, that the loss of typical enzymatic design is not depending on histological grade of tumor differentiation. On the contrary each prostatic carcinoma represents a heterogenic population without any specificity. The morphological pattern alone does not allow conclusions as to degree of malignancy.
