Current treatments for oropharyngeal squamous cell carcinoma and the move towards molecular therapy.

Abstract

Objectives: In this review, we discuss oropharyngeal squamous cell carcinoma (OPSCC) treatment options with a focus on the molecular mechanisms of OPSCC in head and neck squamous cell carcinoma (HNSCC) and head and neck cancers (HNCs). Treatment can be radical intent (aim for cure) or palliative intent (aim for disease control and symptom management). OPSCC is a prominent subset of HNSCCs in Australia and the Western World.

Method: We looked at the current conventional treatment options with an overview of recent advances and future endeavours.

Key findings: We identified that radiotherapy is the primary management for OPSCC in most countries, including the USA, UK, NZ, and Australia. In contrast, surgery is only considered for superficial OPSCC or neck surgery. If surgery is incomplete, then definitive management still requires radiotherapy.

Conclusion: Molecular therapy is largely at the preclinical stage, with cetuximab, nivolumab, pembrolizumab, Lenvatinib, and bevacizumab being tested clinically currently.
