Early Prostate Cancer Treatment: What You Need to Know

How is prostate cancer treated?
With the introduction of prostate-specific antigen (PSA) testing, rates of early prostate cancer detection have risen. Now, there's a higher risk of over-diagnosis and over-treatment of the disease. The available options for early prostate cancer treatment all entail significant potential side effects. Instead, your doctors may consider a more conservative approach to manage early stage prostate cancer.
This is likely to apply for patients with low-risk prostate cancer (e.g. Gleason grade group 1 or Gleason score 6 and below), who face a lower risk of mortality from prostate cancer. For most patients with higher-risk prostate cancer (e.g. Gleason grade group 2 or Gleason score 7 and above), the treatment options available include surgery or radiotherapy.
The best treatment for prostate cancer in its early stages depends on your age, expected quality of life, and risk of advanced prostate cancer.

Active surveillance and watchful waiting
If you have low-risk prostate cancer, your doctor will talk to you about the best plan moving forward. Two strategies for conservative prostate cancer management include: active surveillance and watchful waiting.
Active surveillance is designed to prevent unnecessary treatment and, consequently, avoidable side effects for men with early prostate cancer (and a life expectancy of 10 years or more).
Patients are closely monitored through structured surveillance programs. This involves regular follow-ups that include PSA testing, clinical examinations, magnetic resonance imaging (MRI) and repeat prostate biopsies.
Your doctor will monitor your results for signs that suggest the presence of more aggressive disease. If your cancer shows signs of advancing, treatment can then start as soon as possible. With this strategy, active surveillance ensures that you undergo treatment only when necessary.

Generally, active surveillance is targeted towards those with low-risk prostate cancer and a life expectancy of over 10 years and beyond. This strategy of regular testing helps keep a close eye on your cancer while allowing you to live your life without needing to risk the side effects of prostate cancer treatment.
On the other hand, if you are older or have other serious health issues that lower your life expectancy below 10 years, it’s quite likely that early prostate cancer will never grow fast enough to disrupt your life. In this case, watchful waiting would be recommended. This strategy prioritizes comfort rather than cure as you age, meaning fewer tests for you, while still watching for any need to intervene to mitigate painful symptoms.
Surgery
A radical prostatectomy may be recommended if the tumor is localized at the prostate. This procedure involves the complete surgical removal of the prostate (including the pelvic lymph nodes in certain situations) and is often performed via a minimally invasive approach with robotic assistance.
The possible side effects of prostate removal include incontinence and impotence besides the general surgical risks. These side effects may also occur with other forms of treatment for prostate cancer. You and your doctor should be able to decide the best choice for you, based on your risk and personal preferences.
Radiation therapy
Radiation therapy is another established treatment option for those who prefer to directly treat early prostate cancer. Options can include externally-delivered radiotherapy also known as external beam radiation therapy (EBRT), low dose-rate brachytherapy or high dose-rate brachytherapy.
Radiation therapy differs from surgical treatment (radical prostatectomy) in the duration of treatment as multiple sessions may be needed (externally delivered radiotherapy) and in the side effect profile. The most important side effects arise from the collateral damage done to surrounding organs within the radiation field (e.g. the bladder and rectum), which leads to passing of blood in the urine or bowel motion.
There is also a higher risk of developing a second cancer due to the DNA damage that radiation causes in normal tissues, around five to ten years post-treatment.

Focal therapy
In addition to radical prostatectomy, EBRT and brachytherapy, alternative modalities have emerged as potential therapeutic choices for patients with early prostate cancer. These novel approaches have been developed as minimally invasive procedures to offer comparable oncological safety, reduced toxicity, and improved functional outcomes.
Some focal therapy options include high-intensity focused ultrasound (HIFU) and cryoablation of the prostate (also known as cryotherapy). However, there is insufficient data available to establish them as a mainstay of prostate cancer treatment and longer-term data is awaited for these treatment modalities. Your doctor will be able to discuss the availability and suitability of your cancer for these treatments.
What should I do?
If you feel uncertain about deciding on a specific treatment, the following questions could help guide your decision:
- What do you think about issues with urinary or sexual function? Are you able to accept the risk of facing difficulties with them?
- Are you able to accept living with the possibility of cancer progressing?
- Are you okay with the risk of needing to continue with radiotherapy even after surgery?
- Have you spoken to others who have undergone treatments?
Rest assured that early prostate cancer has a near 100% chance of survival up to ten years after diagnosis. You should consider the risks of early prostate cancer treatment and how they will affect your life after cancer, before making a decision with your doctor.
The best treatment for prostate cancer in its early stages is having the right plan, personalized to your preferences. Ideally, it should allow you to live life as you envision while minimizing the possible side effects and disruptions to your life.
