Abstract
In a previous study of colorectal carcinoma, the LDH isoenzyme pattern was determined in 420 tissue biopsies from 36 surgical specimens. The LDHIV/LDHII ratio was increased in tumour tissue, but in a number of cases increased ratios were found in the morphologically uninvolved tissue as well. This was especially pronounced in cases with multiple tumours. The isoenzymatic changes were interpreted therefore as a possible indicator of an early process of malignant conversion. In order to test this hypothesis the original material has been reviewed after observation periods ranging from 5 to 7 years. It appears that the mean LDHVI/LDHII isoenzyme ratio of resection edge biopsies is high (0-92) in patients succumbing with local recurrence, differing significantly (P less than 0-01) from the corresponding mean ratio (0-66) in patients clinically cured.
