[Efficacy and safety of cetuximab+irinotecan for unresectable advanced or recurrent colorectal cancer].

BACKGROUND: In July 2008, cetuximab treatment for unresectable advanced or recurrent colorectal cancer was approved in Japan, but there have been few reports on this therapy in Japan. PURPOSE: We retrospectively analyzed the efficacy and safety of cetuximab(Cmab)+irinotecan(CPT-11)for unresectable advanced or recurrent colorectal cancer from October 2008 to April 2010 at 5 centers in the Kanagawa region. PATIENTS AND METHODS: The number of patients enrolled was 38, all of whom were treated after second-line therapy. RESULTS: The RR was 24%. DCR was 68%. TTF was 105 days and OS was 242 days. CONCLUSION: At 5 centers, Cmab+CPT-11 was an effective and safe treatment after second-line therapy.
