Diagnosing Oral Cancer with Raman Spectroscopy

Oral squamous cell carcinoma (OSCC): common, but difficult to detect early – leading to poor prognosis. To address this challenge, researchers from the University Medical Center Hamburg-Eppendorf used shifted-excitation Raman difference spectroscopy (SERDS) to evaluate the molecular composition of OSCC, non-malignant lesions, and physiological mucosa – and whether they can be differentiated by Raman spectroscopy (1).

Based on physiological tissue of the oral cavity, they found that non-malignant and cancerous lesions can be distinguished with high accuracy using SERDS. The method also yielded high accuracy in identifying non-malignant lesions that required confirmation by surgical biopsy.

“Our study shows the potential of Raman spectroscopy for revealing whether a lesion is cancerous in real time,” said lead author Levi Matthies (2). “Although it won’t replace biopsies any time soon, the technique could help reduce the lapse of valuable time as well as the number of invasive procedures.”

About the Author
Olivia Gaskill

During my undergraduate degree in psychology and Master’s in neuroimaging for clinical and cognitive neuroscience, I realized the tasks my classmates found tedious – writing essays, editing, proofreading – were the ones that gave me the greatest satisfaction. I quickly gathered that rambling on about science in the bar wasn’t exactly riveting for my non-scientist friends, so my thoughts turned to a career in science writing. At Texere, I get to craft science into stories, interact with international experts, and engage with readers who love science just as much as I do.
