采用IBAS图像分析系统检测37例膀胱移行细胞癌病人的肿瘤细胞DNA含量，其中35例随访18个月至7年（平均5l个月），结果显示DNA含量和AN出现率增加与肿瘤的恶性程度有关（P＜0.01和P＜0.05）；肿瘤复发亦与非整倍体细胞（AN）出现率密切相关，AN出现率小于10％无复发，＜30％5例复发，＞30％9例复发。研究资料表明，图像分析技术测定细胞核的DNA含量对判断膀胱移行细胞癌病人的分级和预后有重要意义。 IBAS image analysis system was used to detect the DNA content of tumor cells in 37 patients with transitional cell carcinoma of the bladder. 35 patients were followed up for 18 months to 7 years (average 5l months). The results showed that the DNA content and the incidence of AN increased with the malignancy (P <0.01 and P <0.05). The recurrence of tumor was also closely related to the occurrence of aneuploidy (AN). The incidence of AN was less than 10%, no recurrence was found in <30% of 5 cases and> 30% of 9 cases . Research data show that image analysis technology to determine the DNA content of the nucleus of the judgment of bladder transitional cell carcinoma of patients with grading and prognosis of great significance.
