Summary
This summary is machine-generated.Contrast-enhanced computed tomography (CT) accurately assesses depth of invasion (DOI) in oral squamous cell carcinoma (SCC). CT scan effectively predicts cervical lymph node metastasis, with radiographic DOI indicating metastasis risk.
Area Of Science
- Medical Imaging
- Oncology
- Radiology
Background
- Oral squamous cell carcinoma (SCC) staging relies on accurate assessment of tumor invasion depth and lymph node status.
- Computed tomography (CT) is a key imaging modality in head and neck cancer evaluation.
- Accurate evaluation of depth of invasion (DOI) and cervical lymph node metastasis is crucial for treatment planning and prognosis in oral SCC.
Purpose Of The Study
- To evaluate the accuracy of contrast-enhanced CT in determining the depth of invasion (DOI) in oral SCC.
- To assess the efficacy of CT in detecting cervical lymph node metastasis.
- To analyze the relationship between radiographic DOI (rDOI) and the presence of cervical lymph node metastasis.
Main Methods
- Retrospective review of 201 oral SCC patients' imaging and pathological data.
- Comparison of CT-derived rDOI with histopathological DOI.
- Calculation of sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for CT in nodal metastasis detection.
- Analysis of the correlation between rDOI and lymph node metastasis using ROC curves.
Main Results
- A significant correlation was found between rDOI and histological DOI for various oral SCC subsites and for tumors with rDOI > 5 mm.
- CT scan demonstrated a sensitivity of 84.71%, specificity of 50.86%, PPV of 55.81%, NPV of 81.94%, and accuracy of 65.17% for predicting nodal metastasis.
- Tumors with rDOI > 16 mm showed a significantly higher likelihood of cervical lymph node metastasis (P < 0.001).
Conclusions
- CT-derived DOI shows significant correlation with pathological DOI, though not identical.
- CT imaging, utilizing specific radiographic criteria, can predict nodal metastasis with reasonable accuracy.
- Radiographic DOI serves as a valuable predictor for the risk of cervical lymph node metastasis in oral SCC.
