LINAC-based Prostate Stereotactic Radioablation by Amar KISHAN, MD, Assistant Professor

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane)

Recent data suggests that SBRT for prostate cancer has a safety and efficacy profile that is comparable to other forms of radiation. The current NCCN guidelines suggest SBRT be delivered at clinics with “appropriate technology, physics, and clinical expertise.” Though "appropriate technology" is not explicitly defined, much of the published data for SBRT come either exclusively or predominantly from patients treated utilizing a robotic-arm linear accelerator. However, emerging data suggest that gantry-mounted linear accelerators (LINACs) can deliver SBRT safely and effectively as well, implying that the outcomes of SBRT are not necessarily anchored to any particular delivery platform. In this Webinar, we will review the evidence for SBRT in general and specifically discuss important technical aspects as they pertain to gantry-mounted LINAC delivery systems.

When is SABR the Preferred Treatment in Lung Cancer? by Ben SLOTMAN, MD, PhD, Associate Professor

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane)

The clinical use of SABR for early stage non-small cell lung cancer has increased considerable during the last decade. In this webinar, current and future indication for SABR in this disease will be discussed. Treatment of patients with a higher risk of toxicity due to tumor location or presence of interstitial lung disease will be addressed as well.

MRI-based TRAMs for High Resolution Depiction of Tumor versus Treatment Effects by Yael MARDOR, PhD, Nuclear Physicist and Associate Professor of Oncology

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane)

Our treatment response assessment maps (TRAMs) are calculated from standard T1-weighted MRI acquired at a delay post contrast injection. In the TRAMs (3D high resolution maps) active tumors is depicted blue while treatment effects (including pseudoprogression, radiation necrosis, post-surgical changes and more) are depicted red. The TRAMs are routinely used for clinical decision making and recently also for treatment planning in multiple hospitals around the world.

The webinar will present shortly the rationale behind the TRAMs, histological validation, and provide examples of how it is routinely used for decision making in neuro oncology. Additional possible applications and research directions will be presented as well.

Ten Year Evolution of Multiple Metastases Treatment with a Single Isocenter by John FIVEASH, MD, PhD, Professor

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane) - 7:00 am (Chicago)

Dr Fiveash will describe evolving processes for treatment planning, image guidance, treatment delivery and quality assurance for single isocenter multiple target radiosurgery at the University of Alabama at Birmingham.  This presentation will also include workflow issues related to their transition from a framed-based program to frameless treatments.  Finally, he will discuss treatment efficiency and clinical outcomes.
Dr Fiveash serves Vice Chair for Academic Programs for the Department of Radiation Oncology at the University of Alabama at Birmingham and has over twenty years of clinical experience with a variety of radiosurgery platforms and techniques. He has additional appointments in the Department of Neurosurgery and Biomechanical Engineering.

SRT for Cancers of Digestive System by Alexandr PANKRATOV, Professor

1:00 pm (Dublin, Edinburgh, Lisbon, London) - 2:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 8:00 am (Eastern time - New York, Canada) - 9:00 am (Brasilia) - 9:00 pm (Tokyo) - 5:00 am (Pacific time - Los Angeles) - 10:00 pm (Brisbane)

The effectiveness of radiation therapy for esophageal cancer is still insufficient. Why? The role of radiation therapy for gastric cancer is often in doubt, is not it? Radiation therapy for rectal cancer is effective, but there are nuances. Are we doing everything right? The answers to these and other questions in radiotherapy of gastrointestinal cancer we will try to find in this webinar.
