When is it Reasonable and Unreasonable to Consider Hypofractionation as Opposed to Single Session SRS?


Jun
08

Dade LUNSFORD, M.D., F.A.C.S., Professor

June 08, 2020
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)

In this webinar Professor Lunsford will provide his perspective on the role of single session vs multisession (or fractionation) for patients who are appropriately managed by stereotactic radiosurgery. He will emphasize the accumulated knowledge obtained over the last 50 years in more than 1.3 million patients who have had Leksell Gamma Knife radiosurgery and the more than 1000 publications that define outcomes for single session procedures. In the face of the accumulated evidence the limited role for fractionation will be explored.

Role of Radiosurgery in Modern Psychiatric Surgery - Competitive Techniques


Jun
22

Antonio DE SALLES, MD, Professor

June 22, 2020
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)

Psychosurgery in the 1930’s consisted of massive disconnections of the frontal lobes. During more than 20 years of its practice, unacceptable adverse effects demanded technical improvements. Radiosurgery, initiated in the 1950’s, achieved discrete interruptions of brain pathways, which were likely causes for the psychiatric symptoms. It is now in the forefront to help millions of suffering psychiatric patients; it takes advantage of exquisite anatomical and functional cerebral images available for understanding, visualization and targeting specific brain pathways. Professor Antonio De Salles presents the last developments within this passionate field. 
Objectives: Attending this webinar, the Radiosurgery specialist will review the radiobiology of fine Radiosurgery lesions, update knowledge on the historical and contemporary results of Radiosurgery for psychiatric diseases, as well as review the imaging essential for good practice of “Psychiatric Radiosurgery”. Finally she/he will understand the role of the competitive techniques in the field of Psychiatric Surgery.

Model-based Dose Calculation Algorithms for Stereotactic Radiosurgery Treatment Planning


Jul
07

Evaggelos PANTELIS, PhD, Assistant Professor

July 07, 2020
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)

Historically, corrections based on dose-calculation algorithms have been used in stereotactic radiosurgery application for reconstructing patient's dose distributions. The limitations of these algorithms that led to the introduction of model-based dose calculation algorithms in radiosurgery will be presented.

Radiation Necrosis/ARE: Difficulties with Diagnosis and Treatment


Sep
25

Samuel CHAO, MD

September 25, 2020
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)

Radiation necrosis is one of the most feared complication of stereotactic radiosurgery.  With increasing utilization of stereotactic radiosurgery, the incidence of radiation necrosis is also increasing.  Historically, diagnosis had been difficult since surgery or biopsy is not often done and imaging had been imperfect.  More recently, however, perfusion MRI has emerged as helpful modality to help distinguish radiation necrosis from tumor recurrence.  There are other promising modalities currently being investigated, including amino acid PET and radiomics.  Steroids and surgery had been the treatment of choice, but more recently, bevacizumab and laser interstitial thermal therapy have emerged as excellent treatment options for radiation necrosis.  Due to better diagnostic and treatment options, perhaps radiation necrosis should be less feared.  This webinar will review the diagnosis and treatment of radiation necrosis, and discuss future investigations.
