Figure 1. Clinical course. After onset of renal disorder and
initiation of dialysis, TDM revealed that plasma imatinib level was
within the therapeutic range. Thereafter, white blood cell count
decreased to baseline level (3.3-8.6×103/μL ), then
reached complete hematologic response. TDM, therapeutic drug monitoring;
C0, trough concentration; CHR, complete hematologic
response; WBC, white blood cell count; PLT, platelet; X axis on the left
represents WBC count (×103/μL) and creatinine levels
(mg/dL). Y axis on the right represents PLT count
(×103/μL).
