Imaging advances in oral cavity cancer and perspectives from a population in need: Consensus from the UK-India oral cancer imaging group

Abstract

Oral squamous cell carcinoma (OSCC) accounts for a third of the cancer burden in India, with a correspondingly high cancer-specific mortality. Although treatment of OSCC in India mirrors that of high-income nations, extreme burden of disease, late presentation, and the associated advanced stage of disease pose unique challenges in a resource-constrained environment. Despite a multimodal treatment paradigm, survival rates are low. Often the cause for late presentation is the delayed diagnosis, inappropriate investigation and referral, and compromised or incorrect treatment, leading to poor patient outcomes and costs to the health-care provider. To address these issues, the first UK-India Symposium on Advances in Oral Cancer Imaging Symposium was organized in Bangalore, India, in April 2019; participants included radiologists, imaging scientists, clinicians, and data scientists from the United Kingdom, India, Singapore, and the United States. Following the discussions held during this meeting, in this manuscript, we present evidence-based guidance for the role of imaging in OSCC, recommendations for service development, and details of future potential for evolution in head and neck imaging.
