title: Kinetic pattern of human urinary transitional cell carcinoma.
abstract: The potential proliferative activity, expressed as labelling index, has been studied in 24 cases of bladder transitional cell carcinomas. The data showed a wide range of values, varying between 0.4 and 36%. The average proliferative activity was 3.2%. An analysis of the connection between the labelling index and the histological grading has also brought out the existence of a gradient of proliferative activity; average values of 1.6-2.53% and 3.49%, respectively, were found for grades I-II and grade III.
