Cetuximab and irinotecan as third line therapy in patients with advanced colorectal cancer after failure of irinotecan, oxaliplatin and 5-fluorouracil.
Cetuximab (Erbitux) in combination with irinotecan is the most promising combination in heavily pretreated patients with advanced colorectal cancer. Efficacy of this combination was confirmed in the pivotal BOND I study. The aim of the present study was to evaluate efficacy and toxicity of a combination regimen of cetuximab and irinotecan but in contrast to the BOND I study all patients had previously received 5-FU, oxaliplatin and irinotecan and all had progressed during or shortly after completion of treatment. Before January 2005 salvage therapy with cetuximab and irinotecan was not used in Denmark. The Danish government had initiated a national programme for patients with advanced cancer and according to this programme the National Board of Health may approve and finance experimental treatment. From January 2005 to September 2005, 65 consecutive patients were treated with cetuximab (weekly) and irinotecan (each 2 or 3 weeks) at three university hospitals. Median age was 57 years (23-78), and median performance status was 1 (0-3). Response rate was 20%, median TTP was 5.5 months and median OS was 10.4 months. Response and survival was significantly correlated with severity of skin toxicity. Toxicity grade 3 was rare (skin toxicity 8%, diarrhoea 10%, nausea 3%, vomiting 3%, fatigue 8%). Salvage therapy with cetuximab and irinotecan is effective in patients pretreated with irinotecan, and oxaliplatin and in a general population the results from the BOND I study was confirmed.
