UK researchers awarded NIHR grant for oral cancer diagnosis tool

A team of UK researchers has been awarded £534k from the National Institute for Health and Care Research (NIHR) to develop an innovative new instrument with potential to transform oral cancer diagnosis.

Researchers from the University of Liverpool’s Department of Physics, in collaboration with the Liverpool Head & Neck Centre (LHNC), have been awarded a NIHR Invention for Innovation (i4i) grant to develop the Liverpool Diagnostic Infrared (LDIR) Wand.

The tool will rapidly and accurately identify lesions in the mouth that will develop into cancer.

The LDIR wand uses a small number of infrared lasers to predict, based on machine learning algorithm analysis of infrared spectral images of tissue, lesions in the mouth that are not currently malignant but will become malignant in the future.

University of Liverpool physicist, Professor Peter Weightman, who has led the development of this pioneering technology, said:

“This i4i award from NIHR provides us with the opportunity to develop a prototype of the LDIR Wand that has the potential to transform oral cancer diagnosis.

“While this application is focussed on oral cancer our approach should be applicable to any cancer where the diagnosis is based on the analysis of biopsies.”

There are more than 12,000 cases of oral cancer in the UK every year and early diagnosis is vital to improving patient outcomes.

However, identifying those lesions of the mouth (dysplasia) that will become cancerous is difficult, leading to either unnecessary treatments or missed cancer diagnoses.

Currently, dysplasia is diagnosed through a microscopic study of tissue samples from patients, which is time-consuming and, due to human subjectivity, can be unreliable.

Professor Richard Shaw from the LHNC said:

“This instrument addresses a difficult clinical problem in head and neck cancer diagnosis.

“We know that earlier diagnosis is key to saving lives, but predicting cancer risk in oral patches is problematic.

“For some patients we miss a high risk of cancer developing, but for other patients we cannot safely reassure them without better information.”

The NIHR i4i award will fund the development of the LDIR Wand prototype for use in histopathology laboratories.

The ultimate aim of the programme is to develop a device for real-time clinical diagnostics.
