- Adequate bone marrow function (hemoglobin > 10 g/dL, leukocytes ≥ 3.000/mm3, neutrophils ≥1.500/mm3, platelets ≥ 100.000/mm3). Patients with plasma creatinine ≤ 1,6 mg/dL, transaminases ≤2.5 times the upper limit of normal (ULN), total bilirubin ≤ upper limit of normal (ULN), CPK ≤ 2.5 times upper limit of normal (ULN), alkaline phosphatase ≤ 2.5 times the upper limit of normal (ULN) are acceptable. If the increase of alkaline phosphatase is > 2.5 times the upper limit of normal (ULN), then the alkaline phosphatase liver fraction and/or 5' nucleotidase and/or GGT must be ≤ upper limit of normal (ULN).
