Cis-dichlorodiammine platinum (CDDP) has recently been introduced for the treatment of human malignancies. CDDP belongs to the group of heavy metals and has nephrotoxicity, whose side effects limit the dose that can be used in patients. The urinary excretion of lactate dehydrogenase (LDH), gamma-glutamyl transpeptidase (gamma-GTP), alkaline phosphatase (ALP), arylamidase (AA) activity and beta 2-microglobulin was determined in ovarian cancer patients receiving sequential combination chemotherapy with CDDP, adriamycin (ADM) and cyclophosphamide (CPA) (PAC chemotherapy) to evaluate the sensitivity of these indices for acute renal tubular damage and compared with the change in serum BUN, Cr and Ccr values. Increases in enzyme excretion after PAC chemotherapy were more often noticed and the urinary enzyme activity varied up to the 10.4-fold of the control, while serum BUN, Cr and Ccr values remained almost within normal limits. Enzyme excretion returned almost to the normal value in one week. A comparison between the urinary enzyme excretion especially AA value and serum BUN, Cr and Ccr values indicated that the serial determination of the urinary AA excretion pattern is more useful in detecting CDDP-induced nephrotoxicity than that of serum BUN, Cr and Ccr values.
