Lab requirements

Blood counts

ANC ≥ 1.5 x 10^9/L without G-CSF for past 14 days; Platelet count ≥ 100 x 10^9/L without transfusion for past 14 days; Hemoglobin > 9 g/dL without transfusion or erythropoietin for past 14 days.

Kidney function

Serum creatinine ≤ 1.5 x ULN and creatinine clearance (using Cockcroft-Gault formula) ≥ 60 ml/min.

Liver function

Total bilirubin ≤ 1.5 x ULN; if > 1.5 x ULN, direct bilirubin must be ≤ ULN. AST and ALT ≤ 2.5 x ULN.

Cardiac function

Good cardiac function, suitable for curative surgery. Preoperative evaluation by a cardiologist is required if there are clinical indications of underlying ischemic, valvular, or other severe heart diseases. Normal myocardial enzyme spectrum (clinical judgment for non-significant lab abnormalities is acceptable).

Normal function of major organs, meeting the following laboratory criteria: Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L without granulocyte colony-stimulating factor for the past 14 days. Platelet count ≥ 100 x 10^9/L without transfusion for the past 14 days. Hemoglobin > 9 g/dL without transfusion or erythropoietin use for the past 14 days. Total bilirubin ≤ 1.5 x upper limit of normal (ULN); if > 1.5 x ULN, direct bilirubin must be ≤ ULN. AST and ALT ≤ 2.5 x ULN. Serum creatinine ≤ 1.5 x ULN and creatinine clearance (using Cockcroft-Gault formula) ≥ 60 ml/min. Normal coagulation function (INR or PT ≤ 1.5 x ULN). Normal thyroid function (TSH within normal range, or normal T3/FT3 and FT4 if baseline TSH is out of range). Normal myocardial enzyme spectrum (clinical judgment for non-significant lab abnormalities is acceptable).
