The Five Revolutionary Pillars Of Dr. Aaron E. Katz’s Work In Prostate Cancer: Focal Therapy, Cryoablation, And Genomic Scoring
Dr. Aaron E. Katz, MD, FACS, is one of the most prominent names in modern urologic oncology, particularly for his pioneering and persistent advocacy for minimally invasive treatments for prostate cancer (CaP). As of late 2025, his work continues to redefine the standards of care, moving away from aggressive, whole-gland treatments like radical prostatectomy and towards precise, organ-sparing techniques such as focal therapy and cryoablation. This shift is critical, as it offers patients a pathway to cancer control with significantly reduced risk of long-term side effects like urinary dysfunction and sexual dysfunction.
The current landscape of prostate cancer management is heavily influenced by genomic risk stratification, and Dr. Katz remains at the forefront of integrating these advanced tools into clinical practice. His ongoing research and leadership role at NYU Langone Health and the NYU Long Island School of Medicine ensure that his innovative approaches—which focus on quality of life alongside oncological outcomes—are shaping the next generation of urologists and treatment protocols globally. His contributions are regularly cited in major medical journals and guidelines, including the recent 2024 updates.

Pillar 1: The Revolution of Focal Cryotherapy and Focal Therapy
Dr. Katz is widely regarded as a pioneer in the field of Focal Therapy for localized prostate cancer, a treatment paradigm that has fundamentally challenged the traditional "one-size-fits-all" approach of radical treatment. Focal therapy, in this context, means treating only the cancerous lesion within the prostate gland, sparing the healthy tissue around it. This is a crucial distinction from whole-gland treatments like radical prostatectomy or radiation, which often lead to severe side effects.
His preferred method within this paradigm is Focal Cryotherapy, also known as cryoablation. This minimally invasive procedure uses extremely cold temperatures to freeze and destroy the cancerous cells. The precision of this technique is paramount, allowing for the targeted destruction of tumors while preserving the neurovascular bundles responsible for erectile function and the urinary sphincter, which maintains continence.
The goal of this approach is two-fold: achieving excellent oncological control and preserving the patient's quality of life. Dr. Katz’s research, including a Propensity Score Matched Analysis comparing Focal Cryotherapy to Radical Prostatectomy, provides compelling evidence supporting this less-invasive option for select patients with early-stage disease.
Pillar 2: Advancing Genomic Risk Stratification with Oncotype DX GPS
The modern era of urologic oncology demands a sophisticated understanding of a tumor's biological aggression, and Dr. Katz has been a staunch advocate for integrating genomic testing into the clinical decision-making process. He has been a key voice in discussing the value of the Oncotype DX Genomic Prostate Score (GPS) assay.
The Oncotype DX GPS assay is a 17-gene test used for patients with low-risk prostate cancer. It helps doctors more accurately determine the tumor's aggressiveness, moving beyond traditional clinical factors like PSA levels and Gleason scores. By using this genomic risk stratification tool, Dr. Katz can confidently recommend Active Surveillance for men with truly indolent (slow-growing) disease or recommend Focal Therapy for those whose tumors are slightly more aggressive but still localized. This level of personalized medicine is vital in preventing both overtreatment and undertreatment of prostate cancer.
Pillar 3: The INTREPId Clinical Trial and Salvage Cryoablation
Dr. Katz's influence extends into the realm of recurrent disease, where he is leading the charge on innovative solutions for patients whose cancer returns after initial treatment. A major focus in his current practice is Salvage Cryoablation.
This procedure is a second-line treatment for men who have experienced a biochemical recurrence (rising PSA levels) after initial radiation therapy. The challenge with salvage therapy is the high risk of complications due to the previously irradiated tissue. Dr. Katz is currently leading the INTREPId clinical trial in collaboration with the prestigious Dana-Farber Cancer Institute to evaluate the effectiveness and safety of this salvage approach. This trial is crucial for establishing new standards for men facing recurrent disease, offering a potentially curative option that is less invasive than traditional salvage radical prostatectomy.
Pillar 4: Shaping National Guidelines and Best Practices (2024 Updates)
The depth of Dr. Katz’s experience is reflected in his involvement with the creation of national and international clinical guidelines. His expertise in ablative therapies is highly sought after, as demonstrated by his contribution to the development of key documents in 2024.
- AUA/ASTRO/SUO Guideline (2024): Dr. Katz was a contributor to the most recent American Urological Association (AUA), American Society for Radiation Oncology (ASTRO), and Society of Urologic Oncology (SUO) guidelines for salvage therapy for prostate cancer. These guidelines are the gold standard for urologists across the United States.
- Focal Therapy Society Best Practice Statement: He is also a contributor to the Focal Therapy Society’s Best Practice Statement on the use of Whole-gland Ablation for clinically localized prostate cancer. These statements provide essential guidance on patient selection and technical execution for these complex, minimally invasive procedures.
His work ensures that the latest, most evidence-based approaches to focal therapy are disseminated and adopted by the broader medical community, cementing his role as a thought leader.
Pillar 5: Holistic Urologic Oncology and Future Directions
Beyond prostate cancer, Dr. Katz’s practice at NYU Langone Health encompasses a wide range of urologic conditions, including bladder cancer, urinary dysfunction, and sexual dysfunction. His comprehensive approach treats the patient, not just the disease, focusing on the quality of life outcomes that are often overlooked in aggressive oncology models.
His recent research interests also include the use of Androgen Deprivation Therapy (ADT), with a 2024 publication highlighting his continued engagement in systemic treatments alongside his surgical expertise. This dual focus—on cutting-edge technology like cryoablation and molecular diagnostics like the GPS assay, combined with a deep understanding of systemic oncology—positions Dr. Katz at the pinnacle of modern urologic care. His commitment to clinical trials and research, including a Phase I/IB study on new treatment arms, ensures that his patients and the field of urology benefit from the most current and forward-thinking treatment strategies available.
