Abstract:
Objective To observe the impact factors of the diagnostic accuracy of fine needle aspiration biopsy(FNAB)for papillary thyroid carcinoma(PTC).Methods Totally 468 patients with single PTC confirmed by postoperative pathology who underwent FNAB before surgery were enrolled.The impact of clinica,l ultrasonic and pathological features on the accuracy of FNAB diagnosis were analyzed.Results The accuracy of FNAB for diagnosing PTC was 71.37%(334/468).The maximum diameter and location of PTC were both impact factors of the diagnostic accuracy of FNAB.The maximum diameter of 0.7 cm was the optimal cutoff value of FNAB for diagnosing PTC,and the diagnostic accuracy of FNAB for PTC with the maximum diameter＜0.7 cm and those≥0.7 cm was 62.96%(119/189)and 77.06%(215/279),respectively.The diagnostic accuracy of FNAB for PTC located in the difficult and easy area of puncture was 52.53%(52/99)and 76.42%(282/369),respectively.The diagnostic accuracy of FNAB for PTC with the maximum diameter≥0.7 cm and located in the easy area,≥0.7 cm and located in the difficult area,＜0.7 cm and located in the easy area,＜0.7 cm and located in the difficult area was 80.43%(185/230),61.22%(30/49),69.78%(97/139)and 44.00%(22/50),respectively.Conclusion The maximum diameter and location of PTC were both impact factors of the diagnostic accuracy of FNAB.
