MR-guided Adaptive Stereotactic Radiotherapy by Miguel PALACIOS

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)

Magnetic resonance imaging (MRI) offers the best anatomical information and it can be used for adaptive radiation therapy.  In this webinar an overview of the key components to implement stereotactic magnetic resonance adaptive radiotherapy (SMART) will be discussed. Examples will be highlighted with the MRIdian system (ViewRayTM), which enables to perform continuous MRI during RT delivery and rapid adaptive planning and beam-delivery control based on visualization of soft tissues.

New Frontiers: SBRT for primary kidney cancers by Shankar SIVA

12:00 pm (Dublin, Edinburgh, Lisbon, London) - 1:00 pm CET (Amsterdam, Berlin, Bern, Paris, Rome, Stockholm, Vienna) - 7:00 am (Eastern time - New York, Canada) - 8:00 am (Brasilia) - 8:00 pm (Tokyo) - 4:00 am (Pacific time - Los Angeles)

Primary kidney cancer has historically been considered a resistant tumour to radiotherapy. However, with the incidence of primary kidney cancers increasing in the developed world at the same time as an increase in life expectancy and prevalence of obesity, there are a growing number of patients who may present with inoperable primary kidney cancer.  Advances in technologies have facilitated the application of ablative radiation as a viable alternative in this scenario. In this webinar, we cover the biological and technical considerations for kidney SBRT, as well as update the current evidence base.

#11 - March 28, 2017

Post-operative SBRT by Arjun SAHGAL

The objective of this presentation is to understand the current evidence as it pertains to the rationale for post-operative SBRT, the clinical data to support it, the technique and current consensus guidelines with respect to contouring, and the issues with respect to the presence of hardware and response determination.

#10 - March 14, 2017

SRS for Spine Tumors by Samuel RYU

In this webinar session, I will cover the topic of Stereotactic Radiosurgery (SRS) for spine tumors. In this context, I will review the safety and efficacy of SRS for spine metastasis, and discuss the ongoing RTOG (NRG) 0631 trial. There will be an emphasis on the spinal cord partial volume tolerance and radiosurgical decompression of malignant spinal cord compression.

#9 - February 28, 2017

Radiosurgery for Uveal Melanoma by Pavel IVANOV

Over the years SRS has been established as a reliable eye-sparing option in the management of uveal melanoma against enucleation. However it cannot be called a routine procedure in daily radiosurgical activity due to the necessity of close cooperation with ophthalmologists. A detailed review of all stages of the treatment procedure emphasizing the most crucial points such as the reliability of eye fixation, imaging requirements, treatment planning and post-treatment care, will be given in this Webinar.

#8 - February 13, 2017

Exploring, Understanding and Exploiting the Radiobiology of Radiosurgery by John KIRKPATRICK

Stereotactic radiosurgery (SRS) provides a unique ability to ablate tumors while minimizing damage to surrounding normal tissues.  While the efficacy and safety of SRS have been established based on several decades of treatment of intracranial and, more recently, extracranial disease, the underlying radiobiology is controversial.  In this presentation, we will present and discuss the evidence and opinions on the fundamental and clinical aspects of radiobiology at high dose/fraction, focusing on the reduction of what is known to guide clinical practice, today, and what needs to be understood to optimize SRS, in the future.

#7 - January 31, 2017

SRS for Pituitary by Jason SHEEHAN

In this webinar, I will cover the topic of Stereotactic Radiosurgery (SRS) for pituitary adenomas. In this context, I will review the safety and efficacy of SRS for nonfunctioning and functioning adenomas. In addition, I will discuss the results of multicenter trials on this topic.

#6 - January 17, 2017

SBRT as an alternative for surgery in early stage NSCLC by Ben SLOTMAN

SBRT is now the standard treatment for patients with medically inoperable NSCLC. SABR is safe, effective and is associated with limited toxicity. These excellent results have led to the question whether SABR can also be used in medically operable NSCLC patients. In this webinar, after a short overview of the accomplishments of SABR in medically inoperable patients, available evidence from non-randomized and randomized studies in operable patients will be discussed.

#5 - December 12, 2016

SRS for Meningiomas by Laura FARISELLI & Marcello MARCHETTI

Meningiomas are rare benign tumors. The surgical excision still remains the first treatment option but, when a complete removal is not achievable, an alternative treatment modality has to be considered. In this sense, the radiosurgery represents the rising treatment paradigm.
The present report, focus on the main problems related to the radiosurgery of the anterior skull base meningiomas. Particularly the radiobiology, the rationale and the limits of the single and multisession radiosurgery as well as the risk of toxicity will be debated.

#4 - November 22, 2016

SBRT for Liver by Brian CZITO & Fang-Fang YIN

This talk was focused on 1) The rational of for liver SBRT; 2) The clinical indications for liver SBRT; 3) The management strategies (fractionation and post treatment assessment) for SBRT; 4) SBRT workflow; 5) Delivery techniques and 6) The motion management techniques.

#3 - November 07, 2016

Radiobiology of Radiosurgery (a neurosurgeon’s perspective) by Antonio DE SALLES

Radiosurgery has revolutionized Neurosurgery, Radiation Oncology and Medical Physics. The matched surgical results and even superior in many instances with radiation delivery precision asks for novel Radiobiology understanding... read more

SRS for Brain Metastases by Bodo LIPPITZ

There has a been a recent paradigm change in the treatment of brain metastases. On one hand, there has been significant progress in developments of chemotherapy, on the other hand, recent data have raised significant doubts concerning effectiveness and safety of Whole Brain Radiotherapy. With increasing survival of cancer patients with brain metastases, the requirements in terms of efficacy and quality of life are being re-evaluated. The high efficacy and low complication rates of stereotactic radiosurgery, even in radio-resistant or multiple metastases, solve a number of the mentioned shortcomings of fractionated WBRT. Technicalities of radiosurgical treatment will be discussed.

#1 - October 11, 2016

SRS physics - Imaging and QA by Ian PADDICK

This 60 minute presentation covers Quality Assurance tests for radiosurgery, including the QA of image distortion, which potentially can represent the largest factor in treatment uncertainty.
