Summary
This study adapted thin prep (TP) for thyroid fine needle aspiration (TFNA) to improve nodule diagnosis. The technique achieved high sensitivity (94.44%) and specificity (98.79%) for cytomorphologic evaluation.
Area of Science:
- Cytopathology
- Endocrinology
- Surgical Pathology
Context:
- Thyroid nodules require accurate diagnosis to guide treatment.
- Thyroid fine needle aspiration (TFNA) is a key diagnostic tool.
- Improving the specificity and sensitivity of TFNA is crucial for patient management.
Purpose:
- To evaluate the efficacy of thin prep (TP) technique in improving cytomorphologic diagnosis of thyroid nodules.
- To assess the sensitivity and specificity of TP compared to conventional smear (CS) in TFNA.
- To adapt TP methods within available laboratory resources for routine use.
Summary:
- A prospective study of 200 thyroid nodules diagnosed using ultrasonography-guided TFNA.
- Samples were processed using both conventional smear (CS) and thin prep (TP) methods.
- TP preparations demonstrated high diagnostic accuracy with a sensitivity of 94.44% and specificity of 98.79%.
Impact:
- Thin prep (TP) offers an effective method to enhance cytomorphologic evaluation of thyroid nodules via TFNA.
- The adapted TP technique provides acceptable preparations with high diagnostic performance.
- This approach can improve the diagnostic yield of TFNA, aiding in better clinical decision-making for thyroid nodules.
