There is a paucity of data regarding molecular subtypes of pure ductal carcinoma in situ (pDCIS).
We evaluated the expression of ER, PR, HER2, Ki67, and p53 and DNA ploidy in 118 pDCIS and 100 invasive breast carcinomas (IBCAs) by routine IHC and classified them according to molecular subtypes.
Quantification of biomarkers and DNA ploidy was performed by image analysis.
Expression of ER, PR, and high ki67 was more frequent in pDCIS compared to IBCA.
High-grade tumors had lower ER and PR expression, high Ki67, overexpression of HER2 and p53, and DNA aneuploidy.
Luminal A and HER2 subtypes were more common in pDCIS, and triple negative was more prevalent in IBCA.
In both groups, HER2 and triple negative subtypes were characterized by high ki67, overexpression of p53, and DNA aneuploidy compared to luminal subtypes.
Molecular subtypes of IBCA are distinct from those of pDCIS.
Invasion is characterized by change in phenotype in some tumors.
