That's great news. I'll help put it all in context, and then also address the big picture on PNI...
First, as a newcomer to this site, perhaps you are not yet familiar with the PROSTATE CANCER QUANDARY famous article, which is really more about
PC treatment quandary. I posted this last month to another member, island time:

This awareness is captured in an article called THE PROSTATE CANCER QUANDARY, but I might argue it would be more precisely labeled THE PROSTATE CANCER TREATMENT QUANDARY, since one could posit that there are several other quandarys associated with PC. I'll just copy/paste directly from the article (in italics):
The quandary in prostate cancer medicine is best summarized by Dr. Willet Whitmore, former Chief of Urology at Memorial Sloan Kettering Cancer Center: “When cure is possible, is it necessary? When cure is necessary, is it possible?”
Another very wise urologist, Dr. Paul Shellhammer, once used the words of Whitmore to further explain that we know there are two kinds of prostate cancer and we hope there is a third.
1. There is the kind that can be cured, but need not be cured.
2. There is the kind that needs to be cured and cannot be cured.
3. We all hope there is the kind that needs to be cured and can be cured.

These three kinds of PC align pretty closely with the low-, intermediate- and high-risk case categories which are described in the "Newly diagnosed..." thread (hopefully you've already read that). There are some exceptions; for example, the intermediate-risk category is further subdivided into a favorable risk side and an unfavorable risk side, and many favorable intermediate-risk cases need no immediate treatment at all.
Your 4+7 put you solidly in the unfavorable intermediate risk category. Your re-classification to 3+4 knocks you down toward the favorable intermediate side, but the PNI may be the influencing factor.
PNI does seem to confer an increased risk of extraprostatic extension (EPE) of tumor. However, in a Epstein study, men with isolated EPE at radical prostatectomy had a roughly 50/50 likelihood (plus or minus about
10 percentage points depending on Gleason and margin status) of biochemical recurrence-free (BCR-free) survival a decade after surgery. So it's only a percent of a percent risk that PNI indicates BCR. Therefore, with specific regard to surgical treatment options, the increased risk of EPE posed by the presence of biopsy PNI should not serve as a contraindication to RP.
My layperson's opinion, you are in the Shellhammer category that "needs to be cured and can be cured." With respect to the method of cure (treatment), PNI does provide at least some incentive to look at non-surgical treatments.
good luck
