In head-and-neck squamous cell carcinoma (HNSCC), the expression patterns of sex hormone receptors differ between HPV-positive and HPV-negative patients. Estrogen receptor alpha is associated with HPV-positive tumors, while androgen and progesterone receptors are correlated with poor patient prognosis.
Background/Aim: Head-and-neck squamous cell carcinoma (HNSCC) is the fifth most common cancer in the world and human papillomavirus (HPV) is an important risk factor for this neoplasm. Recent studies showed an association between sex hormone receptors and pathogenesis and/or prognosis in patients with HNSCC. The aim of this study was to clarify the expression patterns of sex hormone receptors in HPV-positive and HPV-negative HNSCC and their associations with tumour biopathology and biological behaviour. Materials and Methods: Scientific literature indexed in PubMed about sex hormone receptors in HNSCC was retrieved and critically analyzed, to obtain an overview of expression patterns and their possible implications for tumour biopathology and prognosis. Results: Sex hormone receptors were more frequently detected in oropharyngeal tumours compared with HNSCC from other locations. ER alpha was associated with HPV-positive tumours. The androgen and progesterone receptors were associated with poor patient prognosis. Estrogen receptor alpha (ER alpha) is implicated in the biopathology of HNSCC in different ways, by promoting DNA hypermutation and facilitating HPV integration thus contributing to an immunogenic phenotype, but also by cooperating with the epithelial growth factor receptor (EGFR) to promote resistance to therapy. Conclusion: The expression of sex hormone receptors may be of prognostic value in specific tumour subgroups, but the use of hormonal therapies for HNSCC is still not in close sight.
