An investigation was undertaken to quantify and correlate the nuclear and DNA-content modifications in the different grades of noninvasive urothelial papillary carcinoma. Nuclear area and a roundness factor were studied by histomorphometry in 35 cases, and the DNA content was analyzed in 27 cases. The values of the nuclear area and the roundness factor increased from normal-looking urothelium to grade 3 tumors. The DNA-content analysis indicated a progressive change of ploidy and the presence of an aneuploid (greater than 4c) population in some of the grade 2 and grade 3 lesions. A high coefficient of correlation between the nuclear abnormalities and the DNA content was found.

Abstract

An investigation was undertaken to quantify and correlate the nuclear and DNA-content modifications in the different grades of noninvasive urothelial papillary carcinoma. Nuclear area and a roundness factor were studied by histomorphometry in 35 cases, and the DNA content was analyzed in 27 cases. The values of the nuclear area and the roundness factor increased from normal-looking urothelium to grade 3 tumors. The DNA-content analysis indicated a progressive change of ploidy and the presence of an aneuploid (greater than 4c) population in some of the grade 2 and grade 3 lesions. A high coefficient of correlation between the nuclear abnormalities and the DNA content was found.
