Renal damage in mice after sequential cisplatin and irradiation: the influence of prior irradiation on platinum elimination

Abstract

Doses of 4-6 mg kg-1 c-DDP given 6 months before renal irradiation caused only a modest increase in functional radiation damage (DEF 1.1). These effects could be explained by additive toxicities and the damage was much less than when c-DDP was given 3-6 months after irradiation. Pharmacokinetic studies did not demonstrate any decrease in the rate of platinum elimination after previous low-dose renal irradiation.
