PURPOSE: Recently, p16 has been included in the TNM guideline for oropharyngeal carcinomas. The role of HPV and p16 in hypopharyngeal and laryngeal carcinomas has not yet been established sufficiently. METHODS: Hundred and thirty-four patients with hypopharyngeal and laryngeal carcinomas were included in this retrospective analysis. Only patients with known HPV status were eligible for the investigation. Survival probabilities were estimated for different risk factors. RESULTS: Eighty-five patients presented with laryngeal carcinoma and 49 patients with hypopharyngeal carcinoma. 8% were HPV positive (10.6% laryngeal, 4.1% hypopharyngeal carcinoma). Median follow-up time was 58 months. We observed a significantly better overall survival for patients with an early tumor stage compared to advanced carcinoma. One of the hypopharyngeal HPV positive carcinomas was also p16 positive and one was p16 negative. Of the nine HPV positive laryngeal carcinomas, four were p16 positive and five p16 negative. Neither patients who were HPV positive nor patients positive for p16 showed a significantly better outcome than HPV or p16 negative patients. In contrast, nicotine pack-years showed a highly significant correlation with survival in our patient collective. CONCLUSIONS: The data suggest that tumor stage and nicotine exposure seem to have the highest impact on survival in hypopharyngeal and laryngeal squamous cell carcinoma patients. There is no evidence for a better survival for p16 positive or HPV positive patients with hypopharyngeal or laryngeal squamous cell carcinoma. HPV seems to play a minor role in these entities of head and neck carcinoma.
