- Age between 18-75 years;
- ECOG (Eastern US Cooperative Oncology Group) score: 0-1;
- Has sufficient organ function:
- Hemopoietic function: hemoglobin ≥ 90 g / L, platelet ≥ 80 g / L × 109 / L, neutrophils ≥ 1.5 × 109/L
- Liver function: ALT and AST \< 2.5 × ULN;
- Renal function: serum creatinine \< 1.5 ULN;
- Willing to participate and informed consent signed;
You may not qualify if:
- Patients with mutations in any of KRAS, NRAS, or BRAF, microsatellite instablility-High;
