What Is Prostate Cancer? A Comprehensive Guide

Prostate cancer is the most common cancer in men, with well over 200,000 new cases diagnosed in the United States each year. Understanding the diagnostic process and treatment options is crucial for those affected by this disease. With this comprehensive guide, dive into the key aspects of prostate cancer, including the importance of the PSA test, the significance of the Gleason Score, and the role of the pathology report in determining the cancer stage. Explore the various treatment options available as well as the relative survival rates associated with prostate cancer. The goal is to help you better understand prostate cancer and how to navigate the complexities of this disease.

Understanding Your Prostate Cancer Diagnosis

Your doctor diagnoses prostate cancer through a series of tests. Learn about each one so you can understand more about your condition and treatment options.

PSA (Prostate-Specific Antigen) Test

The PSA test is a blood test used primarily to screen for prostate cancer. The test measures the amount of prostate-specific antigen in your blood. PSA is a protein produced by both cancerous and noncancerous tissue in the prostate. Interpretation of the PSA levels helps in the detection of prostate cancer.

Pathology Report

The pathology report provides detailed information about the type and extent of the cancer. It identifies the Gleason Score, defines the stage of the cancer, and helps determine the best treatment strategies.

Gleason Score

The Gleason Score is a grading system that helps determine the aggressiveness of prostate cancer. It evaluates the patterns of cells in the prostate and assigns a score from 2 to 10, with 10 being the most aggressive cancer. The Gleason Score plays a key role in choosing the most suitable treatment.

Cribriform Pattern

Cribriform patterns are associated with a more aggressive form of prostate cancer. The presence of cribriform growth in biopsy specimens is an important factor in determining the severity of the disease, especially for Gleason Score 7 or lower.

A Guide to Prostate Cancer Treatment

Factors that will guide your prostate cancer treatment plan include your general health, age, and the stage and grade of your cancer. The main treatment alternatives for prostate cancer include active surveillance, surgery, radiation therapy, hormone therapy, and chemotherapy.

Active Surveillance

Active surveillance is a treatment strategy often suggested for men with low-risk prostate cancer. It involves closely monitoring the cancer rather than treating it right away. In this approach, the doctor can delay treatment until necessary to avoid potential side effects.

Active surveillance is appropriate for men who have a lower Gleason score, indicating less aggressive prostate cancer. This approach involves regular PSA screenings, digital rectal examinations, and occasional repeat biopsies to monitor any change in the condition.

Surgery (Prostatectomy)

Prostatectomy, the surgical removal of the prostate gland, is a common treatment for prostate cancer. Different types of surgery are available, depending on the extent and location of the cancer.

The two main types of prostate surgery are open prostatectomy and robotic prostatectomy. The latter is less invasive and may result in fewer complications. Possible side effects of this surgery include urinary incontinence and sexual dysfunction. Depending on the location of the diseases, a nerve-sparing surgery technique may be an option, which gives you a better chance of keeping normal erections and urinary functions.

Radiation Therapy

Radiation therapy uses high-energy rays to kill cancer cells. Medical professionals can administer it externally or through small radioactive implants placed inside your body (brachytherapy). External beam radiation targets the prostate gland from outside your body. Stereotactic radiation therapy (SBRT) is a newly available technique in external radiation, and it shortens the treatment course significantly. Advanced machines, such as cyber knife, are specifically designed for SBRT. Brachytherapy, on the other hand, involves the insertion of radioactive seeds directly into the prostate gland. Both methods can cause short-term side effects like frequent urination and fatigue.

Hormone Therapy

Hormone therapy, another treatment option, aims to reduce levels of male hormones, like testosterone, that can stimulate the growth of prostate cancer cells.

Doctors administer hormone therapy through injections, oral medications, or surgery to remove the testicles. It can cause side effects like decreased sexual desire, hot flashes, and loss of bone mass.

Chemotherapy and Immunotherapy

For more advanced or high-risk cases of prostate cancer, or those that don’t respond to hormone therapy, chemotherapy and immunotherapy may be suitable options.

Chemotherapy uses drugs to kill rapidly growing cells, including prostate cancer cells. Immunotherapy, meanwhile, boosts the body’s own immune system to fight cancer. Both treatments come with potential side effects, including fatigue, nausea, and a weakened immune system.

The correct choice of treatment varies for each individual, and it’s always wise to discuss all possible options, including their benefits and risks, with your healthcare team.

Understanding Prostate Cancer Survival Rates

The prognosis of prostate cancer is generally favorable, with outcomes greatly influenced by factors such as the stage of cancer at diagnosis, age, and overall health. One way to understand survival rates is through relative survival rates.

Relative Survival Rate

Relative survival rate compares the survival of men with prostate cancer to the survival expected in men without the cancer. It provides a percentage estimate of the proportion of patients expected to survive the effects of their cancer, taking into account that men can die from other causes as well.

The American Cancer Society reports 5-year relative survival rates for localized and regional prostate cancer to be nearly 100%, which means men with these stages of prostate cancer are, on average, likely to live as long as men who do not have the disease. The 5-year survival rate falls to 34% for prostate cancer that has spread to other parts of the body.

These rates are based on historical data, and advancements in diagnostic techniques and treatments can result in better outcomes. Individual prognosis can depend on a variety of factors, and your healthcare team can provide the most relevant information based on your personal circumstances.

Lifestyle and Supportive Care for Prostate Cancer Patients

Living with prostate cancer can be challenging and requires more than just medical treatment. Adopting a healthy lifestyle and leveraging various supportive care services can not only help manage side effects and enhance the overall quality of life, but also potentially improve survival.

Diet and Exercise Recommendations

Diet and exercise play a substantial role in overall health and well-being, particularly for those diagnosed with cancer. A balanced diet rich in fruits, vegetables, lean proteins, and whole grains can provide the necessary nutrients your body needs to function and heal.

Exercise lessens fatigue and supports mood. Regular physical activity can also reduce the risk of other health conditions, such as heart disease. A routine endorsed by your doctor, such as moderate intensity exercises like walking or swimming, can be beneficial.

Psychological and Emotional Support

Prostate cancer can take a heavy toll on your emotional well-being. You may feel anxious, depressed, and stressed, which are common reactions to a cancer diagnosis and treatment.

Psychological and emotional support can come from various sources, such as counseling, support groups, and communal activities, that help to alleviate stress and provide a feeling of connectedness with others facing similar challenges. Your healthcare team can guide you towards suitable resources.

Remember that each person’s experience with prostate cancer is unique, and so is their coping strategy. Whether it is through diet, exercise, or emotional support, finding what works best for you can make a significant difference to your overall well-being during and after cancer treatment. Research is ongoing to find new ways to treat prostate cancer, and new therapies are emerging all the time.
