目的 探讨细针吸取活检（ Ｆ Ｎ Ａ Ｂ） 细胞学检查对甲状腺乳头状癌的诊断价值。方法 以术后病理诊断为对照，光镜下观察不同级别乳头状癌的针吸涂片中的单个细胞参数、细胞团参数和继发性改变。结果 在１２６ 例乳头状癌中，细胞学诊断正确者１１６ 例（ 占９２ ．１ ％ ） ，可疑者２ 例（ 占１ ．６ ％ ） ，假阴性者８ 例（ 占６ ．３ ％ ） 。在诊断正确的１１６ 例中，细胞学分级正确者１１３ 例（ 占９７ ．４ ％ ） 。同期细胞学诊断为乳头状癌者未见假阳性。结论 Ｆ Ｎ Ａ Ｂ 对甲状腺乳头状癌的定性和分级诊断均准确可靠。还探讨了假阴性的原因和诊断中应注意的问题。
Objective To investigate the diagnostic value of fine needle aspiration biopsy (F N A B) cytology for thyroid papillary carcinoma. Methods Postoperative pathological diagnosis was used as a control. The single cell parameters, cell mass parameters and secondary changes in the needle smears of different grades of papillary carcinoma were observed under light microscope. Results In 126 cases of papillary carcinoma, 116 cases (92.1%) were diagnosed correctly by cytology, 2 cases (1.6%) were suspicious, and 8 cases (6.3%) were false negative. Among the 116 cases with the correct diagnosis, 113 cases (97.4%) had the correct cytological grade. There was no false positive in the diagnosis of papillary carcinoma in the same period. Conclusion F N A B is accurate and reliable for qualitative and graded diagnosis of papillary thyroid carcinoma. Also explored the causes of false negatives and problems that should be noted in the diagnosis.
