The Evaluation of Ultrasonography Results of Patients with a Fine Needle Aspiration Biopsy and Pathology Diagnosis of Papillary Thyroid Cancer: A Single Center Study

Abstract

Aim We aimed to measure the accuracy of the results of FNAB fine needle aspiration biopsy and preoperative ultrasonography US in patients whose pathologic diagnosis was thyroid cancer and who underwent total thyroidectomy in this study Material and method A total of patients who had undergone thyroidectomy between January and September were included in the study The data of the patients who underwent FNAB following US investigation at our clinic and were diagnosed with thyroid cancer after surgery were evaluated retrospectively Multinodular tissue formation was present on thyroid ultrasonography in all patients The findings that were accepted as ultrasonographically suspicious for malignancy during nodule evaluation were as follows a solid and hypoechogenic nodule a nodule with microcalcifications a nodule with irregular borders a nodule without a halo the length of the nodule being longer than the width increased nodule vascularity on Doppler ultrasonographic evaluation The number of nodules that underwent FNAB the diameter echogenicity hyperechogenic isoechogenic hypoechogenic heterogeneous content solid solid cystic cystic microcalcification presence the presence or absence of a peripheral halo whether the border was regular or irregular and whether the nodule was vascular were noted in the US reports Fine needle aspiration biopsy results and postoperative pathologic diagnoses and ultrasonographic findings of the patients diagnosed with papillary thyroid carcinoma were compared Results Of the patients who underwent thyroidectomy were female and were male The mean age was plusmn years A family history of thyroid or other cancers was present in patients The pathology results of the patients whose previous fine needle aspiration biopsy result was papillary thyroid cancer were also consistent with papillary thyroid cancer Of the patients found to have thyroid cancer papillary carcinoma was present in patients and papillary microcarcinoma in patients Although the incidence of malignancy was high in solid hypoechogenic nodules nodules with vascularization nodules with an anterior posterior diameter transverse diameter ratio gt and nodules without a halo in our study the incidence of malignancy was seen to be less in patients who had a nodule with microcalcification and an irregular border The incidence of cancer was high in nodules cm in size Conclusion FNAB should be performed in patients with a nodule and suspicious US findings to decide whether they should undergo surgery US is a guiding and non invasive examination that can reduce the unnecessary FNAB and surgery rate in US patients
