Study Published on Nature.com Supports Role of Tissue Autofluorescence in Screening for Oral Cancer
Vancouver, British Columbia (FSCwire) - LED Medical Diagnostics Inc. ("LED" or the
"Company") (TSX-V: LMD) is pleased to announce the results of a meta-analysis on the clinical use of autofluorescence to assess
its accuracy for oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMD) and investigate its
applicability in general dental practice. The study by Luo et al [1] titled
"Accuracy of Autofluorescence in Diagnosing Oral Squamous Cell Carcinoma and Oral Potentially Malignant Disorders: A Comparative
Study with Aero-Digestive Lesions" was published in Scientific Reports, an online, open access journal from the publishers of
Nature, a leading weekly international scientific journal.
The study was a meta-analysis of previously published data to assess the accuracy of autofluorescence in diagnosing
OSCC and OPMD and reported the findings of statistical analyses conducted on 24 previously reported studies detecting OSCC and
OPMD in 2761 total lesions. The study reported a pooled sensitivity and specificity of the use of autofluorescence for the
detection of OSCC and OPMD of 0.89 and 0.80 respectively and concluded that autofluorescence is a promising, non-invasive tool
for the early diagnosis of OSCC and OPMD. The study’s authors also remark that using autofluorescence technology as an adjunctive
imaging tool may be most reliable in the hands of oral specialists but that the use of promising clinical decision making
algorithms could facilitate its adoption in primary care.
"The results of this study will be of great interest to patients and practitioners alike," commented Dr. David
Gane, CEO of LED. "The results further validate the use of autofluorescence-based imaging tools, such as the VELscope, in
the management of oral tissue abnormalities, including oral cancer. This report adds to the growing body of evidence that
corroborates the use of the VELscope as an effective adjunct in screening for the presence of oral cancers and pre cancers. As
acknowledged in the study, adjunct diagnostic aids are desperately needed by front-line dental practitioners to facilitate the
early detection of OSCC and dysplasia.”
1 "Accuracy of Autofluorescence in Diagnosing Oral Squamous Cell Carcinoma and Oral Potentially
Malignant Disorders: A Comparative Study with Aero-Digestive Lesions" has been published online in the Scientific Reports, Nature
Publishing Group (Scientific Reports, Article number: 29943, Published online: July 15, 2016, doi:10.1038/srep29943). For access

Dr. David Morgan, CTO of LED’s wholly-owned subsidiary, LED Dental Inc., remarked, “The authors’ conclusion
pertaining to the importance of using autofluorescence within a clinical decision-making algorithm for general practitioners is
something that we wholeheartedly support and have been advocating for years. It is also important to note that although
this study is a very thorough analysis of the peer-reviewed literature relating to early diagnosis, the VELscope Vx is not
approved as a stand-alone diagnostic device but rather as an adjunct to enhance the visualization of oral abnormalities.”
There are more than 40,000 new cases of oral cancer diagnosed in the United States alone every year and early
detection is critical for survival; when oral cancer is detected early, the five-year survival rate rises from less than 50% to
more than 80%. VELscope systems are used during more examinations for oral cancer and other oral diseases than any other
adjunctive device. For more information, visit www.velscope.com.
