From January 1992 to January 1993, specimens from bladder tumours of 75 patients were analyzed by cytometry (FCM). Our data show a good correlation between tumour stage and grade, and tumour ploidy. Furthermore, aneuploid tumours showed progression more often than diploid tumours. A larger number of patients admitted to the study and a more prolonged period of follow-up will be necessary to confirm our initial data and to investigate whether a correlation exists between FCM and tumour progression and patient survival.
