Dr. Haas on CyberKnife and the Future of Prostate Cancer Treatment

PRECISION, PREVENTION AND PERSONALIZED CARE

By: Lennard M. Goetze, Ed.D – HealthTechReporter.com



Editor's Note: This interview was originally conducted on June 28, 2024, by HealthTech Reporter as part of our ongoing series highlighting breakthroughs in non-invasive cancer care. As a publication dedicated to medical innovation and diagnostic advancement, we proudly support the pioneers leading safer, smarter, and patient-focused alternatives to traditional treatment. Dr. Jonathan Haas stands at the forefront of this movement, championing the evolution of precision radiation through CyberKnife technology. His work reflects the continued momentum in redefining survivorship, reducing side effects, and tailoring treatment to the individual—hallmarks of the next generation in cancer therapy.

In the ever-evolving world of cancer care, few voices resonate with the clarity and compassion of Dr. Jonathan Haas, a leading radiation oncologist at NYU Langone Health. With thousands of successful patient outcomes under his care, Dr. Haas is a national advocate for innovative, patient-centered therapies—particularly CyberKnife®, a cutting-edge stereotactic radiation system transforming how prostate cancer is treated.

In a recent interview, Dr. Haas offered a detailed, deeply human perspective on cancer survivorship, clinical innovation, and the enduring power of tailored medicine. This article captures Dr. Haas’ insights, drawing from decades of clinical practice and his unwavering belief that the best outcomes arise from treating the whole patient—not just the disease.


Prostate Cancer in Context: Risk, Reality, and Readiness

“Being a man is the biggest risk factor,” Dr. Haas states plainly, pointing out that prostate cancer is one of the most common cancers in men, with its incidence increasing with age. Yet, not all diagnoses demand action. “Many men die with prostate cancer—not from it.” His approach starts with evaluating whether treatment is necessary at all. For many, active surveillance may be more appropriate than aggressive intervention.

When intervention is required, Dr. Haas emphasizes a data-rich, individualized strategy. “We look at the Gleason score, PSA levels, imaging studies like MRI or PET scans, and now we integrate genomics—studying the RNA profile of the cancer cells themselves.” This molecular profiling allows clinicians to tailor treatment with the precision of an Armani suit, as he puts it, ensuring that no two patients are treated the same.

Genetic predisposition, family history, and ethnicity—particularly among African American men—can increase risk. Diet also plays a role. Dr. Haas recommends the Mediterranean diet for its anti-inflammatory and metabolic benefits, highlighting a holistic view of patient health.


From Nine Weeks to Five Days: The CyberKnife Revolution

Dr. Haas provided a detailed breakdown of the evolution of prostate cancer treatment, tracing it from invasive surgeries to the modern era of intelligent radiation systems like CyberKnife. Originally developed in the 1990s by Stanford neurosurgeon Dr. John Adler, CyberKnife was first used to treat brain tumors. By mounting a miniaturized radiation beam on a robotic arm, the system could deliver ultra-targeted doses without invasive head fixation—a revolutionary advancement at the time.

CyberKnife’s precision has since been expanded to treat tumors throughout the body, including the prostate. “We’ve gone from nine weeks of radiation to five days,” said Dr. Haas. “And we’re testing protocols that could bring it down to just two days.”

What sets CyberKnife apart is its ability to track the prostate’s movement—often less than a millimeter—with real-time adjustments, thereby minimizing exposure to surrounding healthy tissue. This level of control dramatically reduces side effects and increases the precision of treatment. “We deliver a high dose to the cancer and a very low dose to everything else,” he emphasized.


WHO’s a Candidate, and WHY Some Patients Say It’s ‘A Walk in the Park’

While every patient experience is unique, Dr. Haas acknowledges that some, like Barrie Kolstein—whose case was previously profiled—describe their treatment as easy or even effortless. “That’s not everyone,” Dr. Haas clarifies, noting that anatomy, gland size, and baseline symptoms can influence outcomes.

Patients with urinary symptoms or gastrointestinal issues may require more nuanced management during treatment. Still, the flexibility of CyberKnife allows for adaptive planning and real-time modifications, ensuring that each patient receives a regimen tailored specifically to their needs. And this is where Dr. Haas’s practice shines—not only in delivering world-class care, but in ensuring patients are never alone in the journey. “We take your hand—and we don’t let go,” he says, echoing his philosophy of long-term, compassionate follow-up. Patients are followed closely for up to five years post-treatment, with PSA monitoring and collaborative care alongside trusted urologists.


Empowering the Patient: Informed Choices, Not Pressured Decisions

In the age of Google diagnoses and a flood of online cancer cures, Dr. Haas urges patients to pause and breathe. “Almost never is prostate cancer a fatal diagnosis at the start,” he says. “You have time. Get multiple opinions. Go to a National Cancer Institute–designated center. And make your decision with a team.”

He takes pride in offering more than just medical advice—he offers mentorship. His clinic keeps a list of former patients willing to speak to newly diagnosed individuals, helping them navigate the emotional and logistical complexities of treatment. “We don’t tell them what to say. They just share their stories,” he says. “Sometimes, hearing from someone who’s been through it makes all the difference.”

Every patient he sees is also evaluated by a urologist. “We don’t operate in silos. The patient, the radiation oncologist, and the urologist form a three-part team. It’s shared decision-making from start to finish.”


A Word to Firefighters and First Responders

Dr. Haas has treated hundreds of 9/11 first responders, including many from the firefighting community. “They’re some of my favorite patients,” he said with affection. “If I told a 70-year-old firefighter he could go back to work tomorrow, every single one of them would jump at the chance.” Yet, he warns, that same dedication can sometimes lead to neglect. “They think they’re invincible,” he says. His advice is simple: get a PSA test. “It’s a single blood test. If you don’t have a strong family history, get one at 50. If you do, start earlier—maybe 40 or 45.”

Early detection, he emphasizes, is not just about survival; it’s about options. “Even if the first treatment doesn’t work—which is rare—you get a second swing at it. You can back up surgery with radiation or radiation with freezing. It’s one of the few cancers where there’s a Plan B.”


CONCLUSION: Precision, Partnership, and a Path Forward

Dr. Haas’ work with CyberKnife is a powerful reflection of where modern oncology is heading—toward precision-based, non-invasive treatments that prioritize both physical and emotional well-being. But beyond the technology lies a philosophy: that no patient should walk alone, and no diagnosis should be a sentence.

From his integration of genomics and imaging to his advocacy for collaborative care, Dr. Haas represents a model of cancer care that is both deeply personal and scientifically advanced. Whether treating lifelong firefighters, newly diagnosed patients, or simply guiding families through difficult choices, his message remains clear: “You are not alone. You have options. And we are here to guide you every step of the way.”
