Abstract: PURPOSE: To develop a mobile application (app) for oral cancer
screening.
METHODS: The app was developed using Android system version 4.4.2,
with JAVA language. Information concerning sociodemographic data and risk
factors for oral cancer development, e.g., tobacco and alcohol use, sun
exposure and other contributing factors, such as unprotected oral sex, oral
pain and denture use, were included. We surveyed a population at high risk
for oral cancer development and then evaluated the
sensitivity/specificity/accuracy and predictive values of clinical oral
diagnosis between two blinded trained examiners, who used movies and data
from the app, and in loco oral examination as gold-standard.
RESULTS: A total of 55 individuals at high risk for oral cancer
development were surveyed. Of these, 31% presented
homogeneous/heterogeneous white lesions with potential of malignancy. The
clinical diagnoses performed by the two examiners using videos were found to
have sensitivity of 82%-100% (average 91%), specificity of
81%-100% (average 90.5%), and accuracy of 87.27%-95.54%
(average 90.90%), as compared with the gold-standard. The Kappa agreement
value between the gold-standard and the examiner with the best agreement was
0.597.
CONCLUSION: Mobile apps including videos and data collection
interfaces could be an interesting alternative in oral cancer research
development.
