ABSTRACT
The incidence of oropharyngeal cancers (OPC) is increasing in the world. Among OPC, those induced by human papillomaviruses have a better prognosis than non-HPV-associated OPC. The objective of this study was to highlight the relevance of HPV16 load, HPV16 DNA integration and HPV16-L1 serology on progression-free survival and overall survival of OPC patients. The PAPILLOPHAR cohort consists of 362 patients with oropharyngeal squamous cell carcinomas prospectively followed up for 5 years after treatment. Tumor biopsies and sera were collected at inclusion to investigate tumor HPV DNA/RNA characteristics and HPV16 L1 serology, respectively. Twenty-seven percent of tumor biopsies were HPV DNA- and RNA-positive and HPV16 represented 93% of HPV-positive cases. Among them, neither HPV16 viral load nor HPV16 DNA integration was associated with overall survival (OS) or progression-free survival (PFS). In contrast, high anti-HPV16 L1 antibody titers were significantly associated with a better OS and PFS. This study reveals that HPV16 load and integration are not relevant prognosis biomarkers in OPC patients.Clinical Relevance High levels of HPV16 L1 antibodies may be useful to predict OPC patient outcome following treatment.ClinicalTrials.gov Identifier NCT00918710, May 2017.
