Gleason 3+4=7: Is Only Radiation Advisable?

Prostate cancer is a common malignancy in men, arising in the prostate gland below the bladder. Accurately assessing its aggressiveness is crucial for guiding treatment. The Gleason score is a primary tool for this assessment, characterizing the tumor’s potential behavior. Understanding these diagnoses and their management is important for those navigating a prostate cancer diagnosis.

Understanding Gleason Score 3+4=7

Pathologists use the Gleason scoring system to evaluate the aggressiveness of prostate cancer cells from biopsy samples. This system assigns a grade from 1 to 5 to the two most prevalent patterns of cancer cells in the tumor. The first number indicates the most common pattern, and the second indicates the next most common. These two grades are added to yield the Gleason score, which ranges from 6 to 10 for diagnosed cancers, as grades 1 and 2 are rarely used.

A Gleason score of 3+4=7 means the most predominant cancer cell pattern is grade 3, and the second most common is grade 4. Grade 3 cells appear more organized and resemble normal prostate tissue, suggesting a less aggressive growth. Grade 4 cells show less organization and a more abnormal appearance, indicating a more aggressive nature. The International Society of Urological Pathology (ISUP) grading system categorizes Gleason 3+4=7 as Grade Group 2, denoting intermediate-risk prostate cancer.

This intermediate-risk classification means the cancer is more aggressive than Gleason 3+3=6 (Grade Group 1), but less aggressive than scores where grade 4 is primary, such as 4+3=7 (Grade Group 3), or higher scores like 4+4=8. The specific order of the numbers, 3+4 versus 4+3, provides insights into the tumor’s likely behavior and informs treatment considerations.

Treatment Options for Gleason Score 3+4=7

For Gleason 3+4=7 prostate cancer, various treatment modalities are considered, with radiation being one primary option.

External Beam Radiation Therapy (EBRT)

EBRT uses high-energy X-ray beams directed at the prostate from outside the body. This treatment damages cancer cells’ genetic material, preventing their growth and division, while minimizing harm to healthy tissues. EBRT is administered in daily sessions over several weeks.

Brachytherapy

Brachytherapy involves placing radioactive sources directly into the prostate gland. Low-dose-rate (LDR) brachytherapy implants tiny radioactive “seeds” permanently, releasing radiation over months. High-dose-rate (HDR) brachytherapy uses temporary radioactive sources for short periods, delivering a high dose before removal. Both types deliver concentrated radiation directly to the tumor.

Radical Prostatectomy

Radical prostatectomy involves the complete removal of the prostate gland and sometimes surrounding lymph nodes. This is a common treatment for localized prostate cancer, including intermediate-risk cases. Robotic-assisted prostatectomy is a minimally invasive technique often used, aiming for less blood loss and quicker recovery.

Active Surveillance

Active surveillance monitors the cancer without immediate treatment, using regular PSA blood tests, imaging (like MRI), and repeat biopsies. Treatment begins only if there is evidence of cancer progression, allowing individuals to delay treatment side effects.

Focal Therapies

Focal therapies, such as cryotherapy or high-intensity focused ultrasound (HIFU), are less common for Gleason 3+4=7 but are being explored. These therapies destroy only cancerous tissue within the prostate, preserving healthy surrounding tissue.

Factors Guiding Treatment Decisions

The choice of treatment for Gleason 3+4=7 prostate cancer is not restricted to radiation alone and involves a comprehensive evaluation of several individual factors.

A patient’s overall health, including other medical conditions, determines suitability for various treatments. Age is another consideration, as treatment may be tailored based on life expectancy.

Prostate-specific antigen (PSA) levels provide information about cancer activity, and the initial PSA value contributes to risk stratification. The clinical stage, determined through imaging (like MRI or bone scans), indicates if the cancer is confined to the prostate or has spread. The volume of cancer within the prostate, or extent of tumor involvement in biopsy samples, also influences recommendations.

Patient preferences are a key part of shared decision-making. Individuals consider potential side effects, including impacts on urinary function, bowel habits, and sexual health. Lifestyle factors and personal values regarding quality of life are discussed with the medical team. This individualized approach ensures the chosen treatment aligns with the patient’s circumstances and priorities.

Navigating Your Treatment Journey

Receiving a diagnosis of Gleason 3+4=7 prostate cancer requires informed decision-making.

Seeking multiple opinions from specialists provides a broader understanding of available options. This helps confirm the diagnosis, explore approaches, and build confidence in the chosen path.

Understanding each treatment option, including benefits and side effects, empowers individuals to make choices aligned with their values and health goals. The decision-making process should not be rushed, as this prostate cancer often progresses slowly, allowing time for careful consideration.

Following treatment, regular follow-up and monitoring are essential. This involves periodic PSA blood tests, physical examinations, and discussions about any ongoing symptoms or side effects. Initial follow-up appointments may occur every few months, gradually becoming less frequent over several years. While a diagnosis of Gleason 3+4=7 is a serious condition, it is manageable.
