title: Nuclear DNA ploidy in mammary carcinomas; using nuclear size as co-parameter reveals more complex patterns.
abstract: Static DNA measurements using nuclear size as a co-parameter have been made on cell populations from 106 consecutive patients with proper imprints from fresh tumour tissues or fine-needle aspirates. When DNA content is plotted against the nuclear size of each individual cancer cell in a scatter diagram, different patterns are found. These patterns indicate the presence of subpopulations, which may be overlooked using conventional flow cytometric analysis or other techniques relying only on the nuclear DNA content. The presence of these subpopulations might, in addition, interfere with a correct definition and estimation of the percentage of S-phase cells.
