Etoposide (VP16) pharmacokinetics was investigated in three groups of cancer patients: a control group of 18 patients with renal and hepatic function tests in the normal range; a group of 8 patients with renal insufficiency; and a group of 15 patients with abnormal hepatic function. In the control group plasma clearance (Clp), volume of distribution (Vd), and elimination half-life (t1/2 beta) of VP16 were, respectively, 22.8 +/- 1.0 (SE) ml/min/m2, 11.4 +/- 0.8 liters/m2, and 5.6 +/- 0.4 h. In patients with renal insufficiency Clp was 12.8 +/- 1.1 ml/min/m2, Vd was 20.8 +/- 4.9 liters/m2, and t1/2 beta was 19.2 +/- 4.7 h. A statistically significant correlation (P = 0.0000001) was found between VP16 Clp and creatinine clearance. In 12 of 15 patients with abnormal liver tests Clp, Vd, and t1/2 beta were, respectively, 27.9 +/- 2.7 ml/min/m2, 12.4 +/- 1.5 liters/m2, and 5.4 +/- 0.6 h and are thus similar to those of the control group. In the other three cases with abnormal liver function VP16 plasma levels were very low. In these cases VP16 t1/2 beta values were similar (5.1, 4.4, and 5.1 h) whereas Clp values (320, 87, and 96 ml/min/m2) and Vd values (142, 33, and 42 liters/m2) were much larger than in controls. These results suggest that VP16 doses should be reduced in patients with renal function impairment but not necessarily in patients with liver impairment. The high VP16 Vd and Clp values found in a subset of patients with liver impairment require further elucidation.
