Cytofluorimetric evaluation of DNA ploidy in the diagnosis of bladder cancer.

Objective: The aim of the study is to investigate the relationship between urinary cytology, traditional indexes of malignancy of bladder carcinoma and DNA-ploidy (diploid, near-diploid, aneuploid).

Methods: 52 specimens of bladder cancers (transitional cell carcinoma) were obtained from 46 patients at TURB and from 6 patients at radical cystectomy. In every specimen the nuclear content of DNA was investigated using the cytofluorimetric method.
