title: [Cell kinetic study of urogenital tumors utilizing in vitro BrdU-labelling method and anti-BrdU monoclonal antibody].
abstract: With the aim to apply a rapid analytic method of cell kinetics using in vitro BrdU labelling and anti-BrdU monoclonal antibody to the clinical fields, we investigated the cell kinetics of 20 urogenital malignant tumors. The DNA synthesizing cells which take up BrdU in its nuclei can be detected so clearly, since the labelling index (LI) is easily identified. The correlations between LI and age and with histological grade and stage of 14 transitional cell cancers of urinary tract were investigated. There was no correlation between LI and age. The LI of high grade groups (G2 & G3) were significantly higher than that of the low grade group (G1) (p less than 0.05). Also between LI of pT1 group and pT3 group, there was a statistical significance (p less than 0.05) and generally LI tended to increase according to stage progression. Therefore, the cytokinetic data obtained from the before mentioned method can be utilized as a useful marker for measuring malignant potentials of each tumor.
