研究概览
简要总结
- To evaluate efficacy, safety, and feasibility of maintenance therapy with Cetuximab combined with irinotecan or fluorouracil after Cetuximab plus irinotecan and fluorouracil(FOLFIRI) in patients with incurable colorectal cancer.
- The relevant phase III studies reported that the progression free-survival of cetuximab combined with FOLFIRI in advanced colorectal cancer was 4.3 months up to 6.8 months.
This study assumed that the progression free-survival was 5.1 months which was not inferior to the continuous chemotherapy

研究组 & 干预措施
maintenance therapy
Initially, all subjects received 8 cycles of Cetuximab (400mg/m2 d1,250mg/m2 every week or 500mg/m2 every 2 weeks)plus FOLFIRI (irinotecan 180 mg/m2 IV on day 1 , leucovorin 400mg/m2 on day 1 , fluorouracil 400mg/m2 on day 1 and fluorouracil 2400mg/m2 civ46h every 2 weeks) .
After 8 cycles or severe toxicity, patients received maintenance therapy comprising Cetuximab (250mg/m2 every week or 500mg/m2 every 2 weeks) and either irinotecan( 180 mg/m2 IV every 2 weeks) or fluorouracil arm( leucovorin 400mg/m2 on day 1 , fluorouracil 400mg/m2 on day 1 and fluorouracil 2400mg/m2 civ46h every 2 weeks ). In cases of unacceptable toxicity, only the related medication was stopped
