Aims: High-risk human papillomaviruses (HPVs) constitute an important risk factor for tonsillar cancer. This study describes changes in cell adhesion molecules during metastasis of HPV-related and HPV-unrelated tonsillar carcinomas. Methods and results: We examined 48 primary tonsillar carcinoma samples (25 HPV-16 DNA-positive, 23 HPV-16 DNA-negative) and their respective lymph node metastases for their HPV status and for the expression of p16, epithelial cadherin (E-cadherin), β-catenin, and vimentin. A positive HPV-specific polymerase chain reaction finding correlated significantly with p16 overexpression in both primary tumours and their metastases (P
