Leading expert in prostate cancer prevention and treatment, Dr. Jack Cuzick, MD, PhD, explains the critical balance between the significant risks of radical therapy and the benefits of active surveillance for clinically localized prostate cancer, highlighting the diagnostic challenge of identifying which tumors are truly aggressive and require immediate intervention.

The Localized Prostate Cancer Treatment Challenge
Clinically localized prostate cancer presents a significant diagnostic and therapeutic challenge for patients and urologists. Dr. Anton Titov, MD, discusses this complex decision-making process with Dr. Jack Cuzick, MD, PhD. The central question is whether aggressive therapy is always necessary or if observation is a viable option for certain patients.
This challenge is even greater than in early breast cancer, according to Dr. Jack Cuzick, MD, PhD, because the consequences of overtreatment carry more severe morbidity. The decision requires careful consideration of the cancer's potential for progression versus the life-altering side effects of radical treatment.
Radical Prostatectomy Side Effects and Morbidity
Radical prostatectomy, the surgical removal of the entire prostate gland, carries substantial risks that profoundly impact quality of life. Dr. Jack Cuzick, MD, PhD emphasizes that urinary incontinence is a common complication that can persist for up to a year after surgery.
Sexual impotence is another frequent outcome of prostate cancer therapy that significantly affects patients' lives. These side effects make the decision to pursue radical treatment more difficult than in many other cancers, as the functional consequences are immediate and often permanent.
The Problem of Prostate Cancer Overtreatment
Prostate cancer overtreatment represents a significant clinical problem, particularly with increased screening detection. Dr. Jack Cuzick, MD, PhD notes that this is very common in the United States, where PSA screening leads to diagnosis of many early prostate cancers that might never cause symptoms or progress.
Some experts even consider certain early prostate cancers as "pre-cancer" conditions, despite meeting all histological criteria for cancer, including invasion through the basement membrane. The critical insight is that many prostate cancers have indolent behavior and will not progress actively if left untreated.
Screening and the Diagnostic Dilemma
Prostate cancer screening creates a diagnostic dilemma by detecting many early-stage cancers through simple procedures like needle biopsy. Dr. Anton Titov, MD explores this issue with Dr. Jack Cuzick, MD, PhD, who explains that while screening identifies cancer histologically, it cannot always determine which cancers require immediate aggressive treatment.
The challenge lies in distinguishing between prostate cancers that will remain indolent and those that will progress to cause significant morbidity or mortality. This diagnostic problem underscores the need for better risk stratification tools beyond basic histology.
Identifying Low-Risk Cancers for Active Monitoring
Identifying which patients with prostate cancer can be safely observed and followed is a critical clinical skill. Dr. Jack Cuzick, MD, PhD discusses the importance of determining which patients have low enough risk to justify active surveillance rather than immediate radical treatment.
This approach requires careful monitoring protocols and reliable biomarkers to ensure that if a cancer shows signs of progression, treatment can be initiated promptly. The goal is to avoid unnecessary morbidity from treatment while ensuring patient safety through close observation.
Making Informed Prostate Cancer Treatment Decisions
Making informed decisions about localized prostate cancer treatment requires understanding both the risks of therapy and the natural history of the disease. Dr. Anton Titov, MD and Dr. Jack Cuzick, MD, PhD emphasize the need to identify which patients have high enough risk to warrant immediate radical prostate cancer treatment.
This decision-making process should incorporate multiple factors including PSA levels, Gleason score, tumor volume, and patient age and preferences. The discussion between Dr. Anton Titov, MD and Dr. Jack Cuzick, MD, PhD highlights that a personalized approach is essential, balancing the potential benefits of cancer control against the certainty of treatment-related side effects.

Dr. Anton Titov, MD: Let's discuss prostate cancer treatment. Clinically localized prostate cancer presents a diagnostic and therapeutic challenge.
Dr. Anton Titov, MD: Do we have to resect the whole prostate gland? Do we have to do aggressive therapy of localized prostate cancer? Can we simply observe a patient with local prostate cancer?
Dr. Anton Titov, MD: How to monitor patients with localized prostate cancer? You have led several clinical trials in a localized form of prostate cancer. What did clinical trials show?
Dr. Anton Titov, MD: What is the best therapy for the localized prostate cancer?
Dr. Jack Cuzick, MD: Prostate cancer is an even bigger challenge than early breast cancer. Excessive treatment is sometimes unnecessary in breast cancer. But over-treatment in breast cancer usually does not carry significant morbidity compared with the treatment of prostate cancer.
Dr. Jack Cuzick, MD: A radical prostatectomy is usually associated with urinary incontinence. It can last for up to a year. Prostate cancer therapy often results in sexual impotence.
Dr. Jack Cuzick, MD: So the decision to do a radical treatment of prostate cancer is more difficult. Because the side effects and morbidity are greater in therapy of prostate cancer.
Dr. Jack Cuzick, MD: It is also clear that screening for prostate cancer does lead to the detection of many early prostate cancers. This is very common in the United States.
Dr. Jack Cuzick, MD: There is an opinion even to call some of these early prostate cancers “pre-cancer.” Although all prostate cancers are formally “cancer,” because histologically they satisfy all the requirements of cancer.
Dr. Jack Cuzick, MD: All prostate cancers are invasive. Carcinoma of prostate penetrates through basement membrane. But many of prostate cancers will not progress actively.
Dr. Jack Cuzick, MD: But this is a diagnostic problem in prostate cancer. We can do something as simple as a needle biopsy of prostate gland.
Dr. Anton Titov, MD: Can we decide which patients can be safely observed and followed? What patients with prostate cancer have high enough risk to need radical prostate cancer treatment immediately?
