目的：探讨细针吸取活检细胞学对乳腺癌的诊断价值。方法：以术后病理诊断为对照（１３４例），光镜下观察５２１例乳腺肿瘤的针吸涂片。结果：在５４例乳腺癌中，细胞学诊断正确者４９例（９０．７％），可疑者４例（７．４％），假阴性者１例。同期细胞学诊断为乳腺癌者未见假阳性。结论：细针吸取活检对乳腺癌的定性和分级诊断均准确可靠。
Objective: To investigate the diagnostic value of fine needle aspiration biopsy for breast cancer. Methods: Postoperative pathological diagnosis was used as a control (134 cases). Needle smears of 521 cases of breast tumors were observed under light microscope. Results: In 54 cases of breast cancer, 49 cases (90.7%) were diagnosed correctly by cytology, 4 cases (7.4%) were suspicious, and 1 case was false negative. There was no false positive in the diagnosis of breast cancer in the same period. Conclusion: Fine needle aspiration biopsy is accurate and reliable for the qualitative and grading diagnosis of breast cancer.
