Abstract

Background: Telomerase Reverse Transcriptase (TERT) gene promoter mutation, leading to immortalization of cancer cells, is a potential candidate for pathogenesis and therapeutic target of Tonsillar Squamous Cell Carcinomas (TSCCs) in association with Human Papillomavirus (HPV). However, the prevalence of TERT promoter mutations and their clinical or prognostic relevance in patients with tonsil cancer in association with HPV under the new staging system is not clear. Methods: We analyzed the TERT promoter mutations through real-time peptide nucleic acidmediated PCR methods and detected the HPV status in 80 TSCC patients. Results: The TERT promoter mutation was found in 7.5%, and HPV in 80.0% of the patients. We did not observe any association between TERT promoter mutation and the clinicopathological variables. However, TERT promoter mutation was identified as the independent prognostic factor for Disease-Free Survival (DFS) in TSCC patients. Interestingly, TERT promoter mutation had strong prognostic impacts on worse Overall Survival (OS) and DFS only in HPV-negative tumors. The HPV-negative and TERT promoter-mutated subgroup had the worst prognosis than other subgroups. In addition, the 8th American Joint Committee on Cancer (AJCC) staging system performed better in the discrimination and stratification of T, and N categories, and overall staging than the 7th edition. Conclusion: Our results suggest that a combined analysis of HPV and TERT promoter mutation could define a representative subset of patients and prognostic groups.
