胸腹水细胞学检查对恶性肿瘤的诊断价值

The diagnostic value of pleural effusion and ascites cytology for malignant tumor

目的探讨胸腹水细胞学检查的诊断效果及阳性率的影响因素。方法对同时进行病理学和细胞学检查的胸腹水标本的结果进行统计,将病理学检查确诊为肿瘤细胞的50例标本的细胞学检查结果与病理学结果进行比较。结果细胞学检查阳性27例,与病理学阳性符合率为54%;阴性21例,与病理学阳性不符,占42%;2例因胸腹水细胞较少,没能进行细胞学检查,占4%。结论胸腹水的细胞学检查阳性率虽然略低于病理学检查,但通过检验技术的不断提高,仍可作为一种行之有效的恶性肿瘤早期筛查手段。

Objective To explore the influencing factors of diagnostic efficiency for malignant tumor by pleura1 effusion and ascites cy- tology. Methods The pleural effusion and ascites specimens results which were detected both by pathology and cytology were analyzed. The cy- tology results were compared with the pathology results in 50 cases which were diagnosed with cancer cells by pathology. Results 27 cases were detected by cytology,the coincidence rate with pathology was 54% ,The negative 21 cases which accounted for 42% were not consistent with pa- thology,The remaining 2 cases（4% ） were not performed by cytology because of less cell. Conclusion Despite the positive rate of cytology was slightly lower than that of the pathological examination for the pleural effusion and ascites, with the improvement of the medical laboratory technol- ogy ,the pectoral ascites cytology is still a effective method for the early screening and diagnosis of malignant tumors.
