FOLFOXIGIL
FOLFOXIRI
The FOLFOXIGIL chemoimmunotherapy regimen is composed by FOLFOXIRI chemotherapy and the immunotherapy of GM-CSF and IL-2. FOLFOXIRI: Irinotecan 165 mg/m² + oxaliplatin 85 mg/m² + Levoleucovorin 200 mg/m² + 5-FU 2800 mg/m² cont. inf. 46h all on day 1, repeated every 2 weeks. GM-CSF 150ug s.c. d3-7; Interleukin-2 100MIU s.c. d8-14 and d17-d28, Repeated every 4 weeks. Treatment will be administered until progression, patients' withdrawal of consent, unacceptable toxicity.
