Abstract:
Objective To explore the application value of automated cell DNA ploidy analysis system in the diagnosis of benign and malignant serous cavity effusion.Methods 262 cases of serous cavity effusion(169 cases of pleural effusion,78 cases of ascites,15 cases of pericardial effusion)were treated by centrifugation,2 slices of each sample were made.One of them used for dyeing Feulgen,which given automatic cell DNA ploidy analysis,another one for Papanicolaou staining,with a conventional cytology.The positive detection rate of these 2 kinds of different detection methods for malignant serous cavity effusion were compared.Results 119 cases(45.4％)of 262 cases abnormal were detected by conventional cytology of serous cavity effusion.Meanwhile,113 cases (43.1 ％)were detected abnormal by DNA ploidy analysis in the same samples.73 cases of tumor cells and suspicious tumor cells were found by conventional cytology,and different ploidy cells were found in all of these samples In conventional cells,46 cases of nuclear heterogeneous cells were found,while only 34 cases exist different ploidy cells.Conclusion Automated cell DNA ploidy analysis system is helpful to improve the positive diagnosis rate of serous cavity effusion,which can be used as an important auxiliary means of cytology.
