对８１例卵巢肿瘤的腹水或腹腔冲洗液进行流式倍体分析。５４例恶性肿瘤中发现４５例为异倍体，与术后病理诊断附合率为８３．３３％。２７例良性肿瘤仅３例为异倍体，与病理附合率为８８．８８％。对４７例卵巢癌同时进行细胞学检查，阳性率仅为２９．６２％，显著低于流式分析结果。腹水的流式ＤＮＡ倍体分析为识别良，恶性腹水开辟了一条新的诊断途径。
Flow cytometry was performed on ascites or peritoneal washings in 81 patients with ovarian tumors. 45 cases were found aneuploidy in 54 cases of malignant tumors, and postoperative pathological diagnosis was 83.33%. Only 27 cases of benign tumor aneuploidy, and pathological adhesion rate was 88.88%. 47 cases of ovarian cancer cytology at the same time, the positive rate was only 29.62%, significantly lower than the results of flow analysis. Flow cytometry analysis of ascites opens up a new diagnostic pathway for the identification of benign and malignant ascites.
