Abstract Human papillomavirus (HPV) associated head and neck squamous cell carcinoma (HNSCC) has a far better prognosis than HPV negative HNSCC. Recent studies suggest that long noncoding RNA (lncRNA) moieties may play a role in HPV associated differential HNSCC prognoses. In this study, we examined differential expression of lncRNAs in HPV + vs HPV − HNSCC using The Cancer Genome Atlas database. LncRNAs were categorized based on expression level and survival analysis. A group of eight lncRNAs was identified in which altered expression was associated with both HPV infection and better prognosis. Subsequently, genes coexpressed with these lncRNAs in HNSCC cells were sorted into corresponding co‐expression modules. The lnc‐IL17RA‐11 coexpression module exhibited the greatest correlation with HPV infection and radiotherapy efficacy. We identified the lnc‐IL17RA‐11 transcription factor ER‐alpha as the most likely HPV infection associated factor promoting increased lnc‐IL17RA‐11 levels. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis revealed enrichment among lnc‐IL17RA‐11 co‐expressed genes for functions related to DNA replication and cell proliferation. These observations are consistent with a model in which HPV infection upregulates transcription factor ER‐alpha, which increases levels of lnc‐IL17RA‐11 and coexpressed genes that promote HNSCC cell sensitivity to radiotherapy, thereby improving disease prognosis.
