Prostate Cancer Staging and Survival Rates in New York, NY
After a prostate cancer diagnosis, two questions usually come next: how serious is it, and what does it mean for my future? Staging and grading answer those questions by describing how aggressive the cancer looks under the microscope and how far it has spread. At Prostate Cancer 911, Dr. David Samadi explains every number in your pathology and imaging reports so you understand your diagnosis and can choose the treatment that fits it best.
Two Ways Prostate Cancer Is Classified
Prostate cancer is described by its grade, which reflects how abnormal the cancer cells look and how quickly they are likely to grow, and its stage, which describes the size of the tumor and whether it has spread. Together with your PSA level, these details determine your risk group and treatment options.
Prostate Cancer Grading Systems
Gleason Score
A pathologist examines biopsy tissue and assigns a grade from 3 to 5 to the two most common cell patterns. Adding them together produces the Gleason score. Today, the lowest score reported for cancer is 6, which represents slow-growing disease. Scores of 7 are intermediate, and scores of 8 to 10 indicate aggressive cancer.
How to Understand a Gleason 7
Order matters. A Gleason 3+4=7 means the most common pattern is the less aggressive grade 3, while 4+3=7 means the more aggressive grade 4 predominates. That difference can change treatment recommendations.
ISUP Grade Group
To make results easier to understand, the Grade Group system translates Gleason scores into five categories:
- Grade Group 1: Gleason 6 (3+3), low grade
- Grade Group 2: Gleason 3+4=7, favorable intermediate
- Grade Group 3: Gleason 4+3=7, unfavorable intermediate
- Grade Group 4: Gleason 8, high grade
- Grade Group 5: Gleason 9 or 10, highest grade
The TNM Staging System
The TNM system describes the primary Tumor, whether cancer has reached nearby lymph Nodes, and whether it has Metastasized to distant sites such as bones. TNM findings combine with PSA and Grade Group to determine the overall stage.
What Are the Stages of Prostate Cancer?
Stage 1
Cancer is small, confined to the prostate, low grade (Grade Group 1), and PSA is under 10. It is often found through screening and may be a candidate for active surveillance.
Stage 2
Cancer is still confined to the prostate but may be larger, higher grade, or associated with a higher PSA. Stage 2 is divided into 2A, 2B, and 2C based on these features. Treatment often includes robotic prostatectomy or radiation.
Stage 3
Cancer is locally advanced. It may have grown through the prostate capsule into the seminal vesicles or nearby tissues, or it may be very high grade while still in the gland.
Stage 4
Cancer has spread to nearby lymph nodes (4A) or to distant sites such as the bones, liver, or lungs (4B). Treatment focuses on controlling the disease with hormone therapy and other systemic treatments.
Prostate Cancer Survival Rates
Prostate cancer has one of the highest survival rates of any cancer, especially when found early. According to American Cancer Society data based on SEER statistics, five-year relative survival rates are approximately:
- Localized (confined to the prostate): more than 99%
- Regional (spread to nearby tissue or lymph nodes): more than 99%
- Distant (spread to bones or other organs): about 37%
These numbers reflect large groups of men diagnosed years ago and cannot predict any one person’s outcome. Treatments continue to improve, and your age, health, and response to therapy all influence your outlook. What the numbers do make clear is that early detection changes everything.

Prostate Cancer Staging FAQs
What is a good Gleason score?
There is no good cancer, but a Gleason 6 (Grade Group 1) is the lowest grade and typically grows very slowly. Many men with Gleason 6 can safely choose active surveillance.
What is the difference between grade and stage?
Grade describes how aggressive the cancer cells look under a microscope. Stage describes how large the tumor is and whether it has spread beyond the prostate.
Is Gleason 3+4 better than 4+3?
Generally yes. In 3+4, the less aggressive pattern predominates, while 4+3 has more of the aggressive grade 4 pattern and is considered higher risk.
What is the survival rate for early-stage prostate cancer?
For prostate cancer that has not spread beyond the prostate, the five-year relative survival rate is more than 99%.
Can stage 4 prostate cancer be treated?
Yes. While stage 4 is usually not curable, hormone therapy, newer hormonal agents, chemotherapy, radiopharmaceuticals, and other treatments can control the disease for many years.
How is prostate cancer staged?
Staging combines your PSA level, Gleason score or Grade Group, physical exam, and imaging such as MRI, CT, bone scan, or PSMA PET. Learn more on our diagnosis page.
