Abstract

Two blind retrospective flow cytometric studies were performed on archival stage O (Ta) papillary grades 1 to 2 transitional cell carcinomas of the bladder to learn whether deoxyribonucleic acid histogram patterns predict disease recurrence and progression. All patients with aneuploid histograms as predicted experienced recurrent disease. In 20 of 28 cases of recurrent disease the ploidy pattern changed during recurrence. Because of this finding we predicted disease progression if 2 or more histograms in the sequence were aneuploid. Two-thirds (8 of 12) of those having more than 1 aneuploid tumor incident experienced invasion, while only approximately a third (6 of 16) lacking repetitive aneuploidy has invasion. Furthermore, of the patients with 2 aneuploid lesions half had progresion within 1 year and two-thirds within 2 years after the second aneuploid lesion. Therefore, it appears that in this disease deoxyribonucleic acid histograms can provide prognostic information beyond that obtained from tumor grade and stage.
