“The detection of oral cancer currently is just visual screen, naked eyes. There's no tool, there's no devices, you are just supposed to look with naked eyes and detect microscopic changes. That is, that's why the accuracy rate is almost as good as a flip of a coin, around 50, 60%”

The claim, plainly

Current standard visual naked-eye screening for oral cancer has an accuracy rate of around 50% to 60%.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Dr. Jayanthi's statement that naked-eye visual screening for oral cancer/lesions has an accuracy rate of around 50% to 60% is well-supported by peer-reviewed systematic reviews and diagnostic meta-analyses. Specifically, a 2021 meta-analysis of 40 studies (Chambrone et al.) established a pooled summary sensitivity of 63% for conventional clinical visual examination in detecting oral potentially malignant disorders and oral cancer. Furthermore, Cochrane reviews and USPSTF evidence syntheses of community screening trials (e.g., Walsh et al. 2021; Brocklehurst et al. 2013) demonstrate baseline visual screening sensitivities as low as 50% to 59% among primary frontline examiners, and clinical-to-histopathological concordance studies (Patel et al. 2011) report naked-eye provisional diagnostic accuracy rates between 50.6% and 63.2%. While sensitivity can be higher for overt lesions assessed by specialists, the 50% to 60% range accurately reflects documented standard visual examination performance.

Chambrone et al. (2021) meta-analysis of 40 studies reported a summary pooled sensitivity of 63% for standard clinical visual examination of oral potentially malignant disorders and oral cancer.
Walsh et al. (2021 Cochrane Review) reported conventional oral examination sensitivity estimates ranging from 50% upward in general population prevalence settings.
USPSTF/Cochrane community screening analyses (Trivandrum trial) noted basic health worker visual screening sensitivity around 59%.
Clinical-to-histopathological diagnostic concordance studies (Patel et al. 2011) report overall provisional naked-eye visual diagnostic agreement between 50.6% and 63.2%.
