目的 :对术前乳腺肿块针吸细胞学检查与术后组织病理学检查结果进行分析 ,了解其与临床的关系。方法 :随机抽出 10 0例相关住院病人进行回顾性分析。结果 :术前乳腺肿块经穿刺细胞学检查的 10 0例中术后病理证实恶性肿瘤 91例 ,良性肿瘤 9例。恶性中 9例为假阳性 ,但其中 8例行了根治或仿根治 ;3例为假阴性。结论 :尽管针吸细胞学检查诊断乳腺肿块性质存在着一定程度的假阴性或假阳性 ,但临床上其敏感性和特异性仍均较高 ,具有相对独特意义 ,值得推广应用。 Objective: To analyze the results of needle aspiration cytology and postoperative histopathological examination of preoperative breast lumps, and to understand its relationship with clinical. Methods: A total of 100 hospitalized patients were randomly selected for retrospective analysis. Results: Totally 91 malignant tumors and 9 benign tumors were confirmed in 100 cases of preoperative breast masses by biopsy. Nine of the malignant cases were false-positive, but eight of them were cured or imitated; three were false-negative. CONCLUSION: Although needle aspiration cytology has a certain degree of false negative or false positive results in the diagnosis of breast masses, its sensitivity and specificity are still high in clinical practice. It is of relatively unique significance and should be popularized and applied.
