SRS for Large Intracranial AVMs by Kita SALLABANDA, MD, 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) - 10:00pm (Brisbane)

Treatment of giant AVMs is a challenge for the neurosurgeon, interventional neuro-radiologist and radio-neurosurgeon. Microsurgical resection of these lesions is difficult and associated with high morbidity and mortality risks, endovascular embolization frequently does not reach complete occlusion of the nidus, whereas radiosurgery is complicated because of the big target volume. There are three different SRS techniques that are utilized for the treatment of big AVMs, (1) stage SRS, (2) stage-volume SRS, and (3) hypofractionation. Their use may result in occlusion of approximately 40-60% of big AVMs. In this Webinar, different modalities of treatment of big AVMs and results of their application will be discussed.

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 hsa 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.

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.
