Abstract
当科において超音波ガイド下吸引細胞診 (FNA) を施行し, 手術により組織学的に確認された甲状腺腫瘍333症例につき検討を行った. 正診率は92.4%, 特異性は100%, 感受性は88.3%であった. またFNA陽性例のうち2回目以降に陽性となった症例が24例 (12.8%) あり, 反復穿刺が重要であると思われた. FNAを手術適応の決定に際し重視することで, 甲状腺手術例における悪性腫瘍の割合が増加し, 不要不急の手術を減少させることが可能になるものと考えられる. 一方, 超音波ガイド下にFNAを行うことで, FNAの診断精度を上げる努力をするとともに, 偽陰性例を見逃さないような総合診断を心がけるべきであると思われた.

Fine-needle aspiration (FNA) biopsy of a thyroid nodule was performed in 797 patients. Ninety-six patients had resection of the thyroid nodule performed subsequent to a one-time FNA biopsy. The surgical pathology of these 96 cases demonstrated a 5.8% false-negative rate and a 9.9% false-positive rate. As a consequence, we prospectively evaluated the routine practice of repeat FNA of cytologically benign thyroid nodules. Repeat FNA confirmed the original benign cytology in 183 (93%) of 196 patien...

The utility of fine needle aspiration (FNA) and physical examination for selecting patients with palpable thyroid nodules for surgery was evaluated in 795 consecutive cases. Surgery was performed in 216 patients based upon the cytological diagnosis and clinical criteria. Excluding 42 patients who were lost to follow-up, the remaining 537 were regularly followed up (range, 2–10 years). Cytological findings were classified as malignant, histologic control recommended (suspicious), follicular tumor...

Introducao: A puncao aspirativa por agulha fina (PAAF) e um metodo eficaz, minimamente invasivo e seguro para o diagnostico pre-operatorio de nodulos tireoidianos e seu desempenho e superior quando guiada pela ultra-sonografia (USG). Objetivo: avaliar o uso da PAAF da tireoide guiada por USG. Pacientes e Metodo: Todos os pacientes submetidos a cirurgia tireoidiana por doenca nodular e com PAAF guiada por USG previa em 2006 foram prospectivamente avaliados no Hospital Ana Costa e na Santos da Irm...

The increased sensitivity of many imaging modalities (ultrasound, computed to mography scan, magnetic resonance imaging) has resulted in the identification of thyroid nodules, measuring 1 cm or less. Usually these small lesions are regarded as incidental and are not sampled by fine-needle aspiration (FNA). However, some of these lesionsundergo FNA because of suspicious radiology findings (multifocality, calcification, etc) or in patients with a history of radiation to the head and neck region. W...

Objective: To assess the accuracy of ultrasonography and cytology in predicting malignancy in thyroid nodules. Design: Prospective open study. Setting: Thyroid centre, Japan. Subjects: 329 nodules in 309 patients examined by a new ultrasound scanner and ultrasound-guided fine-needle aspiration biopsy. Interventions: Comparison of ultrasonographic, cytological, and combined diagnosis with the histological diagnosis. Main outcome measures: Sensitivity, specificity, and accuracy of each diagnostic ...
