目前,大量资料表明恶性肿瘤所致的胸腹水细胞存在明显染色体异常,因此,分析胸腹水细胞染色体可用于辨别良性及恶性疾病。对于那些临床上高度怀疑为恶性疾患而病理及细胞学检查均为阴性学进行积液染色体检查尤其重要。现今,胸腹水染色体检查技术越来越引起人们的广泛兴趣。胸腹水细胞染色体检查在恶性肿瘤中的应用越来越广泛。一、恶性胸腹水的形成恶性肿瘤并发胸腹腔积液临床上并非 At present, a large number of data indicate that there are obvious chromosomal abnormalities in pleural effusion and ascites fluid cells caused by malignant tumors. Therefore, analysis of pleural and peritoneal cell chromosomes can be used to identify benign and malignant diseases. It is especially important for those who are clinically highly skeptical of malignancy and whose pathology and cytology are negative. Nowadays, the chromosomal examination technique of pleural effusion and ascites has attracted more and more people’s interest. The use of pleural and peritoneal cell chromosomes in the detection of malignant tumors has become more and more widespread. First, the formation of malignant pleural effusion and malignant tumor complicated by pleural effusion clinically is not
