Apparently, they are hard to differentiate, and it is possible to have both. The one who can tell you better is Jonathan Epstein at Johns Hopkins. I suggest you call the number on the following website and ask them about how to go about it. I assume it's different from just sending them biopsy slides.

You might want a consult with a medical oncologist in Seattle too. I recommend Celestia Higano at UWSeattle. If anyone there has treated cases like this, it would probably be her. I have no idea how radio-resistant this kind of cancer is. Possibly, pre-treating with docetaxel and hormone therapy will increase its susceptibility to radiation, but I really don't know.
Hi ya all,
I did some digging online, found a paper from Stanford Medicine. In a nut shell both intraductal carcinoma and ductal carcinoma equally suck. I will attempt to add graph here.(fail) Also, I have slightly edited to fit our point. I did not include comparisons to PIN. (prostatic intraepithelial neoplasia) which appears to be a precursor to carcinoma... and we all be way past that. :(
The distinction from ductal carcinoma and intraductal carcinoma is not as critical (as distinction from PIN)
Both are high grade carcinomas
Ductal carcinoma frequently has an intraductal component
Demonstrated by focal presence of basal cells
Prostatic Ductal Adenocarcinoma vs Non-ductal Intraductal Adenocarcinoma
Columnar cells with elongated nuclei vs Cuboidal cells with round nuclei
Cribriform lumens frequently slit-like vs Cribriform lumens usually round
Frequently has true papillae with vascular cores vs Tufts but no true papillae
Usually lacks basal cells vs Basal cells always present
Nuclear size 2-3 x normal vs Nuclear size may be 6 x normal
I am hoping everyone can follow wording, could not get a spreadsheet graph to stay formatted. I used vs to separate what would have been two columns. Also, since I know nothing about
technical biology of this I go with both are high-grade aggressive cancer. I will ask Dr. tomorrow how differences affect treatment.
