• Total bilirubin ≤1.5 × upper limit of normal (ULN);
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 × ULN (≤5 × ULN if liver metastases present);
• Serum creatinine ≤1.5 × ULN or creatinine clearance ≥60 mL/min;
• Prothrombin time (PT), activated partial thromboplastin time (APTT), and international normalized ratio (INR) ≤1.5 × ULN (for patients not receiving anticoagulation);
• Thyroid-stimulating hormone (TSH) ≤ULN (if TSH abnormal, normal free T3 and free T4 are acceptable); (7) Women of childbearing potential must agree to use effective contraception during the study and for 6 months after study completion, with negative serum or urine pregnancy test within 7 days prior to enrollment; men must agree to use effective contraception during the study and for 6 months after study completion, see Section 5.4 for details; (8) Voluntary participation in this study with signed informed consent and good compliance.

You may not qualify if…
