Synchronous, bilateral tonsillar carcinomas: Patient characteristics and human papillomavirus genotypes

The incidence of oropharyngeal squamous cell carcinomas (OPSCCs) is increasing in the Western world [1–3]. The increase is primarily driven by increasing numbers of human papillomavirus positive (HPV+) OPSCCs [1–3]. The subgroup of patients with HPV+ OPSCC has markedly better overall and progression-free survival than HPV-negative (HPV−) patients [4].
