• Patients with nasopharyngeal cancer, paranasal sinus, or cervical lymph nodes metastasis of unknown origin.
• Prior systemic chemotherapy for the squamous cell carcinoma of head and neck, except if given as part of a multimodal treatment for locally advanced disease which was completed more than 6 months prior to study entry.
• Prior anti-EGFR therapy, except if given in association with radiotherapy for squamous cell carcinoma of head and neck which was completed more than 12 months prior to study entry.
• Surgery (excluding prior diagnostic biopsy) or irradiation within 4 weeks before study entry.
• Brain metastasis
