Evaluation of Fine Needle Aspiration Biopsy (FNAB) Results in Macrocalcified Thyroid Nodules

Objective: Thyroid nodule is the most common disease of thyroid gland and closely associated with cancer. The gold standard method in diagnosis Fine Needle Aspiration Biopsy (FNAB). Although relationship between nodules containing microcalcification malignancy well known, there no consensus on relation macrocalcification to adequacy FNAB. In this study, it was aimed compare results FNAB without US examination. Methods: retrospective 466 undergoing 450 patients who applied for biopsy were included study. demographic characteristics patients, features cytopathology Bethesda classification recorded. Nodules divided into two main groups as calcified non-calcified. compared. Results: Transverse sizes found be larger than non-calcified ones (p = 0.003). addition, solid composition, hypoechoic prominent echogenicity, irregular border feature a higher rate group <0.001). No significant difference insufficient sample/non-diagnostic cytology (Bethesda-1) ratios both (19.2% 14.7%). Cytopathologically, number malignant suspected (Bethesda 5 6) (p=0.05). Conclusion: According detection examination does not cause increase results. However, presence increases risk nodule.
