Chromosome Analysis of Cells Combined Biochemistry Test Differented benign and Milignant Pleural Effusion

Objective To find out an new liable method different the pleural's benign and milignant. Methods Pleural effusion is good culture medium of cells, it is easy to get metaphase phase. Assaying cell chromesome of pleural effusion combined with biochemistry test. Results Positive rate of simple chromosome assay is 72.8% conform rate with cytological is 91.7%. Positive rate of chromosome with CEA, chromosome with SF,CEA with SF seperated is 95.5%(43/46),95.6%(44/46),91.2%(41/46). combined test is 97.8%. Conclusion Pleural effusion cell chromosome assay combined with biochemistry(CEA,SF) can improve diagnosis rate.
