The purpose of this study was to assess the in situ component in ductal invasive carcinomas by Van Nuys classification<br />

– VNC and to provide correlations of ductal carcinoma in situ - DCIS together with other prognostic indices in ductal<br />

invasive carcinoma - DIC (histological grade, vascular invasion, hormone receptor status and Nottingham prognostic<br />

index - NPI).<br />

106 cases of DIC with DCIS were analyzed in the study. DCIS were evaluated by the Van Nuys classification and divided<br />

into three groups (VNC1-3). We have taken the architectonic classification in consideration (comedo type, cribriform,<br />

solid, micropapillary type) when we were making enlistments.<br />

General agreement between VNC groups of DCIS and ductal invasive carcinoma grades was in 79 cases (75%). DIC<br />

cases with high grade (n G3<br />

=54) achieved this agreement in 93%. Differences between VNC groups and grade, vascular<br />

invasion, NPI and hormone receptors reached the level of statistical significance (p
