Excellent Question — Let Me Clarify the Risk Classification

You've caught an important distinction, and you're right to question this. Let me explain the nuance carefully, because NCCN risk stratification has specific criteria, and your case sits at an important boundary.


The NCCN Risk Groups for Prostate Cancer

According to NCCN Guidelines for Prostate Cancer, risk groups are defined by Grade Group, PSA, and clinical stage:

| Risk Group | Grade Group | PSA | Clinical Stage | |-----------|-------------|-----|-----------------| | Very Low | 1 | <10 | T1c | | Low | 1 | <10 | T1c-T2a | | Favorable Intermediate | 2 | 10-20 | T2b | | Unfavorable Intermediate | 2-3 | Any | Any | | High | 4-5 | Any | Any |


Why Your Case Is Complex

Your findings:

  • Grade Group: 2 (from the 3+4=7 Gleason score) ✓
  • PSA: 5.14 ng/mL (below 10) ✓
  • Clinical Stage: T1c (found on biopsy, not palpable) ✓

If we ONLY looked at these three factors, you would technically fit FAVORABLE INTERMEDIATE-RISK criteria.


BUT — NCCN Adds Additional Adverse Features

Here's the critical part: NCCN Guidelines recognize that certain pathologic findings make Grade Group 2 disease "unfavorable" even when PSA and stage are favorable.

According to NCCN Guidelines, unfavorable intermediate-risk disease includes Grade Group 2 patients WITH:

  • Perineural invasionYou have this
  • Extensive cancer involvement (>50% of cores positive, or >50% of any core)
  • Multiple Grade Group 2 lesions

Your pathology report explicitly states: "Perineural invasion is present" in BOTH samples.


The Answer to Your Question

You are UNFAVORABLE INTERMEDIATE-RISK, not favorable intermediate-risk, because:**

  1. ✓ You have Grade Group 2 (3+4=7)
  2. ✓ You have perineural invasion (an adverse feature)
  3. ✓ You have cancer in multiple locations (lesion + systematic sampling)

NCCN explicitly states that the presence of perineural invasion in Grade Group 2 disease moves patients from the favorable to the unfavorable intermediate-risk category.


Why This Distinction Matters for Treatment

According to NCCN Guidelines:

| Risk Group | Recommended Approach | |-----------|----------------------| | Favorable Intermediate | Active surveillance may be considered in selected patients | | Unfavorable Intermediate | Active treatment is recommended (RT+ADT or RP) |

For unfavorable intermediate-risk disease, NCCN states (Category 1 - most strongly recommended):

  • Radiation therapy + androgen deprivation therapy (ADT), OR
  • Radical prostatectomy

Active surveillance is not recommended for unfavorable intermediate-risk disease in patients with life expectancy >10 years.


Your Specific Situation

Your cancer has:

  • ✅ Small volume (3 mm, 6% of tissue)
  • ✅ Relatively low PSA (5.14)
  • ✅ Localized to prostate (no spread)
  • ⚠️ BUT: Grade Group 2 + perineural invasion = unfavorable features

This means: You likely need active treatment, but the small volume and low PSA are favorable prognostic factors that your oncologist will consider when discussing treatment intensity and approach.


Revised Questions for Your Oncologist

Given this clarification:

  1. "My pathology shows Grade Group 2 with perineural invasion—does this place me in the unfavorable intermediate-risk category, and does that mean active treatment is recommended?"

  2. "Given my small tumor volume (3 mm) and PSA of 5.14, how does that modify your treatment recommendation compared to a typical unfavorable intermediate-risk patient?"

  3. "Would you recommend radiation + hormone therapy or surgery, and how do the favorable features (small volume, low PSA) influence that decision?"

  4. "How long would hormone therapy last if we choose radiation, and what is the rationale for that duration in my case?"

  5. "Should I have genomic testing (Decipher, Prolaris, or other) to further refine my prognosis and treatment planning?"


Bottom Line

You're absolutely right to focus on the Grade Group 2 + Gleason 3+4=7 combination. However, the perineural invasion is the key finding that moves you into the unfavorable intermediate-risk category according to NCCN criteria. This doesn't mean your prognosis is poor—it means active treatment is recommended rather than observation.

Your small tumor volume and low PSA are favorable prognostic factors that will inform how your oncologist treats you, but the presence of perineural invasion means treatment is indicated.
