title: DNA-malignancy-grading of bladder tumor and its clinical significance.
abstract: The DNA-Malignancy-Grade(DNA-MG) of paraffin-embedded tumor specimens from 38 patients with bladder tumor was determined by image cytometry. A good correlation was found of DNA-MG with clinical staging and histopathological grading. The DNA-MG of T1 and G1 bladder tumor was less than 3.00, while that of T3-4 and G3 bladder tumor was greater than 3.00. The 5-year survival of patients with DNA-MG < 3.00 and > 3.00 was 100% and 36.9%, respectively. The data indicate that DNA-MG plays an important role in the assessment of the prognosis and the planning of treatment.
