Background:Epidermal growth factor receptor (EGFR) is highly expressed in adenoid cystic carcinoma (ACC). The efficacy and toxicity of cetuximab with concomitant platinum-based chemoradio- or chemotherapy in patients with locally advanced or metastatic ACC, respectively, was evaluated.Methods:Eligible patients (9 with locally advanced tumour and 12 with metastases) had positive tumour EGFR expression. The cetuximab loading dose (400 mg m -2) was followed by 250 mg m -2 per week. Locally advanced tumours were irradiated (mean dose 65 Gy) and treated with concomitant cisplatin (75 mg m -2, intravenously). Patients with metastases received concomitant cisplatin and 5-fluorouracil (4 × 1000 mg m -2).Results:For patients with locally advanced disease (median follow-up: 52 months), the median progression-free survival (PFS) was 64 months and the 2-year overall survival (OS) rate was 100%. For patients with metastases (median follow-up: 72 months), the median PFS and OS were 13 and 24 months, respectively. In both groups the objective response rate was >40%. Skin rash, in-field dermatitis, mucositis and vomiting were the most frequent grade 3/4 adverse events.Conclusion:In this single-arm study, the efficacy of cetuximab plus chemoradio- or chemotherapy appeared favourable as compared with historical controls. All side effects were manageable and did not hamper the treatment.
