Absolute concentration of sunitinib (upper panel), SU12262 (middle panel), and the sum of sunitinib plus SU12662 (lower panel) in patients after the 3-day and 5-day continuous infusions of ifosfamide. P-values (Wilcoxon signed rank test) of significant lower or higher relative trough concentrations compared with the trough concentrations observed before the start of ifosfamide infusions (that is, day 0, lime bars) are presented. Day –1 (brown bars) is the sample taken the day before the start of ifosfamide infusion and days 1 (red bars), 2 (blue bars), and 3 (rose bars) are the samples taken 24, 48, and 72 h after the start of ifosfamide infusions, respectively. Data are presented as the mean±s.d. of six observations; n=5 for day 2 in the 3-day schedule (The colour reproduction of this figure is available on the html full text version of the manuscript).
