Value of cell block technique in pathological diagnosis of papillary thyroid carcinoma by fine needle aspiration
Objective:To explore the value of cell block technique in thyroid fine needle aspiration to improve the accuracy of pathological diagnosis of thyroid diseases.Methods:One hundred and thirteen cases of papillary thyroid carcinoma from Hebei General Hospital were randomly selected, and routine cytological smears and cell embedding were performed after fine-needle aspiration. The diagnostic results were confirmed by postoperative pathological results.Results:There was a statistically significant difference in the degree of dissatisfaction between the cell block group (1/113, 0.9%) and the conventional smear group (10/113, 8.8%). In terms of the diagnostic accuracy for papillary thyroid carcinoma, the positive rate in the cell block group (110/113, 97.3%) was significantly higher than that of the conventional smear group (100/113, 88.5%; P<0.05).Conclusion:Compared with conventional cell smear, cell block technique has a higher degree of satisfaction and higher diagnostic accuracy. In addition, cell blocks can also be immunohistochemically stained to solve difficult diagnostic problems.
