Safety and feasibility of every‐other‐week maintenance cetuximab after first‐line chemotherapy in patients with recurrent or metastatic head and neck squamous cell cancer

Abstract

BACKGROUND: In patients with recurrent and/or metastatic head and neck squamous cell cancer (HNSCC), there are no data about an every-other-week cetuximab maintenance schedule after chemotherapy plus cetuximab as first-line treatment. METHODS: We reviewed the safety and feasibility of every-other-week maintenance cetuximab administered at 3 different European centers. RESULTS: Thirty-one patients with recurrent or metastatic HNSCC were treated from 2006 to 2010. Mean cetuximab dose intensity in the maintenance phase was 93%. The major toxicities reported during every-other-week maintenance cetuximab were skin rash (grade 3, 16%; grade 2, 23%), fatigue (grade 3, 3%; grade 2, 16%), diarrhea (grade 3, 7%; grade 2, 13%), hypomagnesemia (grade 4, 3%; grade 3, 3%; grade 2, 19%), and mucositis (grade 3, 3%; grade 2, 23%). CONCLUSIONS: Every-other-week maintenance cetuximab schedule was well tolerated and did not worsen toxicity that occurred during chemotherapy. In daily practice, this simplified schedule could improve compliance and possibly improve quality of life in patients with recurrent or metastatic HNSCC that showed no progression during first-line chemotherapy.
