Cyclin D1 expression was seen in 67.5% of ductal carcinoma and it showed a significant correlation with ER, PgR expression (92% in this study), which is in concordance with other similar studies in literature.
The biological mechanism of CCND1 in carcinogenesis has not been fully examined; but at present Cyclin D1 seems to be an interesting biomarker for the prognosis of ductal adenocarcinoma.
