Newly diagnosed

Hello - I totally agree with what @jeff marc (Jeff Marchi) offers: "There is a problem with treating both intraductal and cribriform as that there is no treatment that is definitive in eliminating it. Surgery was probably better than radiation for Cribriform. But radiation might be usable if you had SBRT radiation followed by multiple sessions of IMRT to the prostate bed and lymph nodes. You need to discuss this with both a urologist surgeon and a radiation oncologist to find out what may be better for you." I totally agree that a radical prostatectomy is the better way to go.
I would add that while you have Intraductal carcinoma, it is still important to know and understand "which type" of Cribriform tissue that you have...and for a reason and outcome that I discovered quite unexpectedly when I did a little research to discover that there are about "eight" types of Cribriform tissue, two of which are nothing to worry about, AND that Cribriform tissue can exist as a "normal" microscopic feature in healthy prostate tissue in some men. In other words, you could have had Cribriform tissue all of your life, and when you got diagnosed with prostate cancer, with Cribriform tissue, that Cribriform tissue may have been there all along. Here is what happened with me:
I wanted to know more about Cribriform tissue, so I did an online search, and much to my surprise, I discovered the above mentioned fact that there are numerous types of Cribriform tissue, but...my post-RP surgical pathology report merely said: "Cribriform: Present". I called my urologist and asked him to have my slides pulled and re-read by the same pathologist so he could tell me what type of Cribriform tissue I have. Outcome: The pathologist modified his original surgical pathology report, correcting himself, that there was in fact NO Cribriform tissue in my prostate tissue"...per my urologist quoting the pathologist, he had made an overly conservative call and decided to say it was there, when upon re-examination, decided that he was wrong, and thus amended his own report. THAT did not instill much confidence in me as to the skill of the pathologist. So...It might be worth having your slides re-read, maybe by a different pathologist with the request to delineate "what type" of Cribriform tissue you have, because it may be "normal" Cribriform tissue.
As I mentioned above, two types are not problematic, while the others span a range of moderately problematic to ominous. It would be good to know, for peace of mind, what you have. I thoroughly believe in maximal understanding of everything about my cancer, so that when new decisions have to be made, I have "ALL" of the history and knowledge about "me" that I can possibly have. I fortunately did not have Intraductal Carcinoma, but I did have Extraprostatic Extension (EPE), left seminal vesicle invasion, and surgical margins which were only found after my prostate was removed and dissected. The left seminal vesicle invasion threw me into a more ominous pT3b category which my doctor told me, means that I have a 25-50% probability of the cancer returning "within" five years. I am hoping I will be in the 50-75% group where it does NOT recur. Good luck to you...keep us posted on your progress.

I'll try to create and drop the link, but here is a screenshot of the article title and authors below my list of the eight types of Cribriform that exist:
1. Clear Cell Hyperplasia Cribriform
2. AIDCP Cribriform
3. IDC-dense Cribriform
4. IDC-nuclear artypia (atypia?) Cribriform
5. IDC-comedonecrosis Cribriform
6. Cribriform Pattern 4
7. Cribriform Pattern 5
8. Ductal Carcinoma Cribriform

Thank you for all who have provided me with advice, wisdom, support and compassion, it is greatly appreciated. I had a PET scan yesterday and today received the first good news since I started this journey; the cancer is contained in the prostate capsule. I meet next week with my MO, and my RO the following week. One sentence (see below) in the pathology report I could use some help with. I know it shows where the lesion is located, but not sure if this is a good or bad location, and have no idea what a SUV max 10.7 (axial 317) means. I would again appreciate any input.
Right posterior basal prostate gland ILLUCCIX avid lesion, SUV max 10.7 (axial 317)

Regarding Cribriform, like I have mentioned on this forum before the chief pathologist at a COE stated these exact words when asked about cribriform: "In summary, the presence of cribriform pattern is documented in all cancers that have pattern 4"

I just think all pathologist don't report it but should specify it and the type of cribriform if 4+
