Cytophotometric investigations of DNA-content in transitional cell tumors of the bladder. Comparison of results with clinical follow up.
Forty-nine patients with transitional cell tumors of the urinary bladder were followed up clinically for a period of at least 36 months (average time 61.4 months). Initial tumors were examined by means of DNA-Feulgencytophotometry. Histologic grading was performed according to Bergkvist et al. (1965). Clinical behavior clearly demonstrates the validity of the grading schedule used and shows the significance of DNA-Feulgencytophotometry for the standardization of bladder tumors and for the comparability of diagnostic and therapeutic results. Determination of the individual prognosis of low-malignancy tumors and the differentiation of histologic borderline cases does not appear to be possible by means of DNA-Feulgencytophotometry.
