Ductal Carcinoma In Situ of the Breast: A Comparative Analysis of Histology, Nuclear Area, Ploidy, and Neovascularization Provides Differentiation Be…

2002

Ductal carcinoma in situ (DCIS) is a heterogeneous group of lesions that has been subdivided into three types: well differentiated (grade I), moderately differentiated (grade II), and poorly differentiated (grade III). Forty-five cases of DCIS were analyzed for image analysis: nuclear area, DNA ploidy, and vascularization in order to establish a more precise correlation between the histologic grade and these morphometric parameters. Our results confirm that the mean nuclear area, DNA ploidy, and microvessel density (MVD) progressively increased from DCIS grade I to DCIS grade III. The analysis of the nuclear area in relationship to DCIS grading demonstrated a progressive increase of values …
