Staging of Prostate Cancer

Prostate cancer is one of the most common cancers in men, and understanding its stage is crucial for determining the best treatment options. The staging of prostate cancer helps doctors assess how far the disease has progressed and whether it has spread beyond the prostate gland to lymph nodes or distant areas.

At Urology of Greater Atlanta, our board-certified urologists specialize in diagnosing and treating prostate cancer at all stages. With multiple locations throughout Georgia, we provide personalized care to help patients make informed decisions. Call us today to schedule a consultation! 

How is the Stage of Prostate Cancer Determined?

Doctors use a combination of clinical tests and imaging studies to determine the stage of prostate cancer. The most common methods include:

• Digital Rectal Exam (DRE) – A physical exam to detect abnormalities in the prostate gland.
• Prostate-Specific Antigen (PSA) Test – Elevated PSA levels may indicate cancer presence or progression.
• Biopsy of Prostate Tissue – A sample of prostate tissue is examined under a microscope to assess the cancer cells’ appearance.
• Gleason Score and Prostate Cancer Grade – This score or grade is based on what is found from the biopsy. It determines how abnormal the cancer looks compared to normal prostate tissue.
• Imaging Tests (MRI, CT Scan, Bone Scan, PET Scan) – Used to check if the cancer has spread beyond the prostate.

These tests help classify the cancer into one of the recognized prostate cancer stages, guiding doctors in creating the most effective treatment plan.

What Are the Prostate Cancer Stages?

The staging of prostate cancer follows the TNM system, which considers the tumor size (T), lymph node involvement (N), and metastasis (M). The four primary prostate cancer stages are:

Stage I (Localized Prostate Cancer)

At this stage, the cancer has not spread beyond the prostate gland. It is often slow-growing and limited to a small part of the prostate. This is called localized prostate cancer and is often managed with active surveillance, particularly for older patients or those with low-risk disease.

Stage II (Locally Advanced Prostate Cancer – Early Stage)

The tumor is larger but still contained within the prostate. Based on the Gleason score, PSA level, and grade group, treatment options may include surgery, radiation therapy, or continued monitoring. Some patients in this stage are still eligible for active surveillance.

Stage III (Locally Advanced Prostate Cancer – Late Stage)

Here, the cancer has spread beyond the prostate but remains in nearby structures, such as the seminal vesicles. This is known as locally advanced prostate cancer, and treatment may involve a combination of:

• Radiation Therapy – Targets cancer cells in and around the prostate.
• Hormone Therapy – Lowers testosterone levels to slow cancer growth.
• Surgery (Radical Prostatectomy) – Removes the prostate gland along with affected tissues.

Stage IV (Metastatic Prostate Cancer)

This is the most advanced stage, where the cancer has spread beyond the prostate gland to nearby lymph nodes (IVA) or other parts of the body, including the bones, other organs, or distant lymph nodes (IVB). Stage IV prostate cancer requires systemic treatments, such as:

• Hormone Therapy – Also called androgen deprivation therapy (ADT).
• Chemotherapy – Used when hormone therapy is no longer effective.
• Targeted Therapy or Immunotherapy – Helps the immune system attack cancer cells.

Because metastatic prostate cancer is more difficult to cure, treatment focuses on managing symptoms and slowing disease progression.

Why Are the Prostate Cancer Stage and Grade Important for Treatment?

The prostate cancer stage is crucial in determining how aggressive treatment should be. A patient with localized prostate cancer may be eligible for active surveillance, while advanced prostate cancer often requires multiple forms of therapy.

The prostate cancer grade, determined by the Gleason score and grade group, measures how abnormal the cancer cells look compared to normal prostate tissue. This classification includes:

• Grade Group 1 – The least aggressive, with cancer cells closely resembling normal tissue.
• Grade Groups 2-3 – Moderate aggressiveness, requiring closer monitoring or treatment.
• Grade Groups 4-5 – Highly abnormal cancer cells, indicating an aggressive form of cancer.

Patients with a higher grade group and Gleason score often require more aggressive treatment, as their cancer is more likely to spread to lymph nodes and other areas.

What Are the Prostate Cancer Risk Categories?

Doctors categorize prostate cancer into different risk groups to help guide treatment decisions. These include:

• Low-risk prostate cancer – A small, contained tumor with a grade group 1 and low PSA levels. Many men in this category qualify for active surveillance.
• Intermediate-risk prostate cancer – A larger tumor with a grade group of 2 or 3 and moderate PSA levels. Treatment options may include surgery or radiation therapy.
• High-risk prostate cancer – A large tumor, grade group 4 or 5, and high PSA levels. Aggressive treatment is necessary, often combining surgery, radiation, and hormone therapy.

This classification ensures that patients receive the most appropriate treatment, balancing effectiveness and quality of life.

Prognosis for Prostate Cancer

The prognosis for prostate cancer varies based on the stage, grade, and risk category.

• Localized prostate cancer has a very high survival rate, with nearly 100% of men surviving for at least 10 years.
• Locally advanced prostate cancer has a high chance of successful treatment, though ongoing monitoring is necessary.
• Stage IV prostate cancer is more challenging, but many men live for years with modern therapies.

Patients with early-stage prostate cancer have an excellent prognosis, while those with metastatic prostate cancer may require long-term treatment to manage symptoms and slow progression.
