At present, the most important is quantitative measurement of immune Some studies indicate CD38 expression superior to measurement tion of measurements of DNA ploidy or proliferation analysis. O Since 1996, the utilization of DNA analysis has significantly decreased, and breast car it is most often performed in patients with node-negative cinoma and other tumors where the clinical correlation is strongest innovations may lead to a revival of However, recent technological interest in clinical DNA analysis. In this regard, Bagwell modified DNA analysis to optimize the accuracy of DNA ploidy and S phase in node negative breast cancer, eliminate spurious technical inconsistencies and apply standardized modeling rules to data analysis and inter pretation. Furthermore, the authors developed a prognostic model that combines DNA ploidy and the S phase into a Relative Risk Index
