Mammary ductal carcinoma natural history

Prognosis for Invasive Ductal Carcinoma
The prognosis of IDC depends, in part, on its histological subtype. Mucinous, papillary, cribriform, and tubular carcinomas have longer survival, and lower recurrence rates. The prognosis of the most common form of IDC, called "IDC Not Otherwise Specified", is intermediate. Finally, some rare forms of breast cancer (e.g. sarcomatoid carcinoma, inflammatory carcinoma) have a poor prognosis.

Regardless of the histological subtype, the prognosis of IDC depends also on its staging, histological grade, expression of hormone receptors and of oncogenes like HER2/neu.
