<p>In this episode of the Dr. Geo Prostate Podcast, we welcome Dr. Jonathan Lischalk, Director of Genitourinary Cancers at MedStar Georgetown University Hospital and former Medical Director at NYU’s NYCyberKnife Center. Dr. Lischalk breaks down the evolution of radiation oncology and how cutting-edge imaging and targeted SBRT (Stereotactic Body Radiation Therapy) are reshaping prostate cancer treatment.</p><p>We explore how imaging advances like MRI and PSMA PET scans are enabling unprecedented precision, the future of genetic-based personalization in prostate cancer therapy, and why fewer, more focused radiation sessions might soon become the new standard. From understanding the biology of radiation dosing to upcoming trials eliminating ADT in select patients, this is a must-listen for anyone looking to stay informed on the forefront of cancer care.</p><p><strong>🔑 Key Learning Points:</strong></p><ul><li><strong>What is SBRT?</strong></li><li>SBRT delivers high-dose radiation with sub-millimeter precision over fewer sessions, minimizing harm to healthy tissue.</li><li><strong>The evolution of imaging:</strong></li><li>MRI and PSMA PET scans now allow radiation to be personalized based on tumor location and surrounding anatomy.</li><li><strong>Radiation then vs. now:</strong></li><li>From “clouds” of radiation in the '90s to sculpted beams today—Dr. Lischalk likens this transformation to upgrading from a flip phone to an iPhone.</li><li><strong>Radiation dose explained:</strong></li><li>It’s not just how much radiation, but how it’s delivered—larger, more targeted doses in fewer sessions are more effective and less burdensome.</li><li><strong>Personalized radiation planning:</strong></li><li>Every radiation plan is customized based on imaging, anatomy, and now genetics. This improves outcomes and reduces side effects.</li><li><strong>The future of personalization:</strong></li><li>Dr. Lischalk discusses new research using genetic tests (like Decipher) to determine who needs radiation, who may avoid ADT, and who may benefit from one single treatment.</li><li><strong>SBRT vs. IMRT and Proton Therapy:</strong></li><li>Head-to-head comparisons show SBRT is equally effective with less treatment time—though more trials are underway, especially for proton therapy.</li></ul><br/><p>________________________ </p><p><strong>Introducing The Dr. Geo Prostate Podcast Exclusive Membership</strong></p><p>We’ll continue bringing you powerful weekly episodes to support your prostate health journey.

<p>How powerful is exercise in the fight against advanced prostate cancer? Dr. Geo speaks with world-renowned exercise oncology expert Dr. Rob Newton from Australia, whose groundbreaking research has shaped how clinicians approach fitness and cancer care. From bone metastasis to androgen deprivation therapy (ADT), Dr. Newton explains how the right exercise, at the right dose, can not only improve quality of life but potentially extend it.</p><p>Together, they explore the science, practical guidelines, and inspiring stories behind using movement as medicine—even for men with metastatic, castration-resistant disease.</p><p><strong>Key Takeaways</strong></p><ul><li><strong>Exercise is medicine</strong> for men with prostate cancer—including advanced and metastatic cases.</li><li><strong>Resistance training</strong> helps preserve or build muscle during androgen deprivation therapy (ADT), reducing side effects like fatigue, bone loss, and metabolic issues.</li><li>Even with <strong>bone metastases</strong>, exercise can be done safely with modified strength programs—<strong>no increase in fractures</strong> observed in studies.</li><li><strong>Muscle strength and fitness</strong> are strongly linked to lower cancer-related and all-cause mortality.</li><li><strong>Myokines</strong> released from working muscles have <strong>direct anti-cancer effects</strong> and support immune function.</li><li>Focus on <strong>large muscle groups</strong> (legs, back, chest) using moderate to heavy weights—<strong>6 to 15 reps per set</strong>.</li><li>Tailor workouts to the individual: more strength training for muscle loss, more cardio for heart/metabolic risk.</li><li>Periodized, varied routines improve outcomes and help patients tolerate treatments like chemo better.</li></ul><br/><p>_________________________ </p><p><strong>Introducing The Dr. Geo Prostate Podcast Exclusive Membership</strong></p><p>We’ll continue bringing you powerful weekly episodes to support your prostate health journey.

<p>In this episode of the Dr. Geo Prostate Podcast, Dr. Geo welcomes Dr. Alberto Vargas, Vice Chair of Oncologic Imaging at NYU Langone Health and expert in prostate cancer imaging.</p><p>They dive deep into the evolving world of diagnostic tools—MRI, PET, CT, and PSMA scans—and how these technologies help detect, monitor, and guide treatment for prostate cancer. Dr. Vargas explains the difference between imaging modalities, when to use them, and how PSMA PET scans are changing the game in identifying recurrent and metastatic disease earlier than ever before.</p><p>Key topics covered:</p><ul><li>MRI vs. PET vs. CT: what each scan shows and when it matters most</li><li>The rise of PSMA PET for finding prostate cancer at extremely low PSA levels</li><li>Why not all PET scans are the same, and how tracers like FDG, Axumin, and PSMA work</li><li>The potential future of prostate cancer diagnosis: fewer biopsies, more imaging</li><li>Limitations, false positives, and how imaging results are interpreted</li><li>The role of imaging in both first-time diagnosis and recurrence</li></ul><br/><p>Whether you're a patient, caregiver, or clinician, this episode offers valuable insight into how imaging helps guide smart, proactive decisions in prostate cancer care.</p><p>----------------</p><p>Thank you to our partners</p><p>The<a href="https://bit.ly/3TVehAx" rel="noopener noreferrer" target="_blank"> ProLon 5-Day Fasting Mimicking Die</a>t is a plant-based meal program designed to provide fasting benefits while allowing food intake.
