Summary
Squamous-cell carcinoma (SCC) antigen shows limited diagnostic value for detecting SCC, with low sensitivity in lung and oromaxillofacial cancers. However, it may be useful for monitoring tumor progression.
Area of Science:
- Oncology
- Biochemistry
- Clinical Diagnostics
Background:
- Squamous-cell carcinoma (SCC) antigen is a biomarker investigated for cancer diagnosis.
- Accurate diagnostic markers are crucial for effective cancer management.
Purpose of the Study:
- To evaluate the diagnostic utility of serum SCC antigen concentrations in patients with squamous-cell carcinoma.
- To assess the specificity of SCC antigen in differentiating SCC from other conditions.
Main Methods:
- Serum SCC antigen levels were measured in 48 untreated patients with lung or oro-maxillo-facial squamous-cell carcinoma.
- SCC antigen was also assessed in control groups including patients with other epithelial neoplasms, inflammatory lung disease, and liver or renal dysfunction.
Main Results:
- Sensitivity for lung SCC was 53% and for oromaxillofacial SCC was 34%.
- Elevated SCC antigen levels were observed in over 50% of patients with abnormal renal function, indicating potential cross-reactivity.
- False-positive rates were 11% for inflammatory lung disease and other epithelial neoplasms, and 7% for abnormal liver function.
Conclusions:
- Serum SCC antigen is not a specific diagnostic marker for squamous-cell carcinoma.
- The primary clinical utility of SCC antigen may be in monitoring treatment response and disease progression in patients with known SCC.
