Abstract

Objectives: Achieving complete tumour resection is one of the main goals of surgery for head and neck squamous cell carcinoma (HNSCC) tumours. Whether biological characteristics of tumours contribute to the surgical resectability and the presence of positive surgical margins (SM) after resection of HNSCC is unclear. We aimed to address this issue. Materials and methods: We used data from The Cancer Genome Atlas (TCGA) to relate the SM status of 356 HNSCC tumours covering five major primary locations (tongue, larynx, tonsils, floor of mouth and buccal mucosa) with data from multiple omics approaches (transcriptomic, genomic and proteomic analyses). Results: We identified three differentially expressed genes whose expression was significantly associated with the presence of positive SM in tongue tumours (n = 144). The three genes (CCDC66, ZRANB2 and VCPKMT) displayed significantly higher mRNA levels in tongue tumours with positive SM compared to tumours with negative SM. The corresponding gene expression signature identified tongue tumours with a positive SM with high sensitivity and specificity (85% and 76%, respectively, Area Under the Curve (AUC) = 0.84). Tongue tumours with this signature were characterised by a high grade, elevated proliferation levels and a tumour stroma with fewer fibroblasts and endothelial cells. Conclusion: Positive SM were found to be strikingly associated with tumour biology in tongue tumours. These findings offer interesting perspectives for biomarker identification and precision surgery in these tumours.
