Abstract
High speed core cut biopsies of breast tumors, sonographically or stereotactically guided, allow an histological examination of the tumor without surgery. It can be used prior to operation for the confirmation of a breast cancer and it can avoid unnecessary breast surgery in benign tumors. Unfortunately, only some centers are equipped with a pathology unit that allows an immediate histological examination. But often these institutes are provided with an experienced cystologist. Thus, the question arises if a cytology taken from the core cut biopsy is as reliable as an histological examination. In a prospective study we performed unroll-cytologies in core cut biopsies of 173 breast tumors in 169 patients consisting of 122 malignant and 51 benign tumors. Histology of core cut biopsies was proven by operational histology in all malignant and in 5 benign tumors. Histology of core cut biopsies could not be judged in 2 cases (lymphoma, gallert carcinoma). Cytological slide preparations were technically inadequate in 4 cases. The false negative rate of histology was 1/120 and 27/120 in cytology. Histology compared with cytology showed the following results: sensitivity 99.2% versus 77.5%, specificity 100% versus 95.9%, positive predictive value: 100% vs. 97.8%, negative predictive value: 98.1% vs. 63.5%, and accuracy: 99.4% vs. 82.8%. The sensitivity of cytology was much worse than that of histology of core cut biopsies. Thus, in our opinion cytology can provide a quick diagnostic orientation, but it cannot replace the more reliable histological examination. Diagnostic or therapeutic decisions should be based upon the more reliable histological results.
乳腺肿瘤的高速核心切片活检,超声或立体定向引导下,允许肿瘤的组织学检查,而无需手术。它可以在手术前用于确认乳腺癌,它可以避免不必要的乳房良性肿瘤手术。不幸的是,只有一些中心配备了病理学单位,可以立即进行组织学检查。但通常这些机构都配备有经验丰富的膀胱医生。因此,出现了一个问题,即从核心切片活检中提取的细胞学是否与组织学检查一样可靠。在一项前瞻性研究中,我们对169例173例乳腺肿瘤的核心切片活检进行了展开细胞学检查,其中122例为恶性肿瘤,51例为良性肿瘤。所有恶性肿瘤和5例良性肿瘤的手术组织学证实了核心切口活检的组织学。2例(淋巴瘤、胆囊癌)穿刺活检组织学不能判断。4例细胞学切片技术不完善。组织学假阴性率1/120,细胞学假阴性率27/120。组织学与细胞学比较结果如下:敏感性99.2% vs 77.5%,特异性100% vs 95.9%,阳性预测值:100% vs 97.8%,阴性预测值:98.1% vs 63.5%,准确性:99.4% vs 82.8%。细胞学检查的敏感性远低于核心切片的组织学检查。因此,我们认为细胞学可以提供一个快速的诊断方向,但它不能取代更可靠的组织学检查。诊断或治疗的决定应基于更可靠的组织学结果。
