Abstract

Background: Despite recent advances, survival outcomes for those with metastatic or recurrent head and neck squamous cell carcinoma (HNSCC) have remained poor. Novel approaches should be investigated to improve outcomes.

Methods: A retrospective chart review was performed of a patient who presented with a TNM classification III HNSCC of the oropharynx, positive for human papillomavirus (HPV) who had a complete response to a human epidermal growth factor receptor 2 (HER2)-targeted therapy. Amplification rates of HER2 in the HNSCC Cancer Genome Atlas Network (TCGA) dataset and the FoundationOne genomic profiling dataset were evaluated.

Results: Comprehensive genomic profiling of the tumor obtained from the dermal metastasis identified amplification of HER2. Data from TCGA and FoundationOne showed that the frequency of HER2 alteration was not observed to vary significantly with HPV tumor status.

Conclusion: This case demonstrates the application of genomic profiling to guide treatments in a patient with HNSCC with advanced metastatic disease refractory to standard of care therapies. © 2016 Wiley Periodicals, Inc. Head Neck 39: E15-E19, 2017.
