Lactate dehydrogenase isoenzyme pattern in uninvolved mucosa of patients with colorectal carcinoma.

Abstract
Colorectal mucosa from patients with colorectal carcinoma was compared with rectal mucosa from a control group. The LDH [lactate dehydrogenase] isoenzyme pattern of uninvolved mucosa proximal and distal to the carcinoma differed from that of normal tissue and resembled that of carcinoma tissue except in the case of uninvolved mucosa proximal to carcinoma of the sigmoid colon, which did not differ from normal mucosa.
