The potential utility of flow cytometric (FCM) analysis in routine diagnostic cytology for effusions was assessed with 104 samples from body cavity fluids. Conventional cytology showed no positivity (0/33) for effusions from patients with non-malignant diseases, and 45% positivity (38/71) for effusions from patients with malignant diseases. Conversely, FCM showed no positivity (aneuploid) (0/33) for effusions from patients with non-malignant diseases, and 18% positivity (13/71) with malignant diseases. In 13 cases examined, 8 cases (62%) showed an identical DNA ploidy pattern between effusion site and primary site. FCM showed positivity in four cytologically negative samples (3 malignant lymphomas and 1 clear cell carcinoma). In cases with malignant lymphoma, conventional cytology showed 40% positivity (4/10) and FCM 60% (6/10) positivity. These results indicate that DNA analysis of cells in malignant effusions does not have a diagnostic value as a routine test, but it may have in cases of malignant lymphoma.
利用104份体腔积液样本评估了流式细胞术(FCM)分析在常规诊断性积液细胞学中的潜在效用。传统细胞学检查显示,非恶性疾病患者的积液无阳性结果(0/33),恶性疾病患者的积液阳性率为45%(38/71)。相反,FCM显示,非恶性疾病患者的积液无阳性结果(非整倍体)(0/33),恶性疾病患者的积液阳性率为18%(13/71)。在检查的13例病例中,8例(62%)积液部位和原发部位之间的DNA倍体模式相同。FCM在4例细胞学检查阴性的样本中呈阳性(3例恶性淋巴瘤和1例透明细胞癌)。在恶性淋巴瘤病例中,传统细胞学检查的阳性率为40%(4/10),FCM的阳性率为60%(6/10)。这些结果表明,恶性积液细胞的DNA分析作为一项常规检查没有诊断价值,但在恶性淋巴瘤病例中可能有诊断价值。
