Study Notes
- Auto-fluorescence is not recommended for routine detection of pre-cancerous or cancerous lesions.
- It is used for intra-operative detection of excision margins in confirmed cancerous lesions.
- Auto-fluorescence is not commonly used in practice today.
- Oral CDx (CDx Diagnostics) is a commercialized technique for obtaining samples of "less concerning" lesions that would not otherwise be biopsied.
- Oral CDx uses artificial intelligence for analysis of trans-epithelial samples.
- Cytology involves the collection and analysis of oral brush biopsies.
- Vital tissue staining with toluidine blue is not FDA-approved for cancer screening.
- Toluidine blue colors cells rich in DNA and sometimes the acidic environment of tumor tissues.
- False positives can occur with hyperkeratotic lesions, erosions, or along ulcer margins.
- Sensitivity and specificity of vital tissue staining for clinically suspicious lesions are 87% and 71%, respectively.
