  • Renal function: serum creatinine ≤ 2.0 mg/dL (0.81 mmol/L)
  • Hepatic function: AST and ALT ≤ 1.5 X ULN unless liver metastases are present, then AST and ALT ≤ 5.0 X ULN; LDH ≤ 1.5 X ULN; bilirubin ≤ 1.5 mg/dL (0.026 mmol/L) Corrected calculated calcium ≤ 10 mg/dL (2.5 mmol/L) Calculation = total calcium - 0.707 (albumin -3.4)Albumin ≥ 3.0 g/dL (0.45 mmol/L)
