| 1 | Cetuximab plus FOLFOX6 or FOLFIRI in metastatic colorectal cancer: CECOG trial显示文摘AIM: To investigate efficacy and safety of cetuximab combined with two chemotherapy regimens in patients with unresectable metastatic colorectal cancer (mCRC). METHODS: Randomized patients received cetuximab with 5-fluorouracil (5-FU), folinic acid (FA) and oxaliplatin (FOLFOX) 6 (arm A, n = 74) or 5-FU, FA and irinotecan (FOLFIRI) (arm B, n = 77). KRAS mutation status was determined retrospectively in a subset of tumors (n = 117). RESULTS: No significant difference was found between treatment arms A and B in the progression-free survival (PFS) rate at 9 mo, 45% vs 34%; median PFS, 8.6 mo vs 8.3 mo [hazard ratio (HR) = 1.06]; overall response rate (ORR) 43% vs 45% [odds ratio (OR) = 0.93] and median overall survival (OS), 17.4 mo vs 18.9 mo (HR = 0.98). Patients with KRAS wild-type tumors demonstrated improved PFS (HR = 0.55, P = 0.0051), OS, (HR = 0.62, P = 0.0296) and ORR (53% vs 36%) and in arm A, improved PFS (HR = 0.49, P = 0.0196), OS (HR = 0.48, P = 0.0201) and ORR (56%vs 30%), compared with patients with KRAS mutated tumors. In arm B no significant differences were found in efficacy by KRAS mutation status. Treatment in arms A and B was generally well tolerated. CONCLUSION: This study confirms that combinations of cetuximab with FOLFOX6 or FOLFIRI are effective and significantly improve clinical outcome in KRAS wild-type compared with KRAS mutated mCRC. | Janja Ocvirk Thomas Brodowicz Fritz Wrba Tudor E Ciuleanu Galina Kurteva Semir Beslija Ivan Koza Zsuzsanna Pápai Diethelm Messinger Ugur Yilmaz Zsolt Faluhelyi Suayib Yalcin Demetris Papamichael Miklós Wenczl Zrinka Mrsic-Krmpotic Einat Shacham-Shmueli Damir Vrbanec Regina Esser Werner Scheithauer Christoph C Zie-linski | 2010 | World Journal of Gastroenterology2010，16，25： | 17 |
| 2 | Cetuximab plus irinotecan in pretreated metastatic colorectal cancer patients:The ELSIE study显示文摘AIM:To evaluate the efficacy and safety of cetuxim-ab plus irinotecan in irinotecan-refractory metastatic colorectal cancer (mCRC) patients from South-East Asia and Australia. METHODS:In this open-label,phase Ⅱ study,the main eligibility criteria were epidermal growth factor receptor-positive mCRC with progressive disease within 3 mo of an irinotecan-based regimen as the most recent chemotherapy. Patients received cetuximab 400 mg/m2 initially,then 250 mg/m2 every week,with the same regimen of irinotecan on which the patients had progressed (4 pre-defined regim-ens allowed). The prim-ary objective was evaluation of progression-free survival (PFS) at 12 wk. Secondary objectives included a further investigation of PFS,and an assessment of the overall response rate (ORR),duration of response,time to treatment failure (TTF),overall survival and the safety profile. RESULTS:One hundred and twenty nine patients were enrolled from-25 centers in the Asia-Pacific region and of these 123 received cetuximab plus irinotecan. The most common recent irinotecan regimen used was 180 mg/m2 every 2 wk which had been used in 93 patients (75.6%). The PFS rate at 12 wk was 50% (95% confidence interval (CI,41-59) and m-edian PFS tim-e was 12.1 wk (95% CI:9.7-17.7). The ORR was 13.8% (95% CI:8.3-21.2) and disease control rate was 49.6% (95% CI:40.5-58.8). Median duration of response was 31.1 wk (95% CI:18.0-42.6) and median overall survival was 9.5 mo (95% CI,7.5-11.7). The median TTF was 11.7 wk (95% CI:9.1-17.4). Treatment was generally well tolerated. The most common grade 3/4 adverse events were diarrhea (13.8%),neutropenia (8.9%),rash (5.7%) and vomiting (5.7%).CONCLUSION:In patients from Asia and Australia,this study confirm-s the activity and safety of cetuxim-ab plus irinotecan observed in previous studies in Europe and South America. | Robert Lim Yan Sun Seock-Ah Im Ruey-Kuen Hsieh Tsz Kok Yau Anthony Bonaventura Arkom Cheirsilpa Regina Esser Matthias Mueser Suresh Advani | 2011 | World Journal of Gastroenterology2011，17，14： | 1 |
