Two Session (Staged) Radiosurgery in Brain Metastases and Other Brain Tumors by Eduardo LOVO, MD

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 I hope to transmit what has changed in my practice as neurosurgeon when I face large symptomatic metastases in the brain and how and why two-session SRS has become our first line of treatment for such lesions. I shall review the current neurosurgical recommendations for treating these tumors in particular, what are the caveats of upfront surgical management, what is the evidence in two-session radiosurgery and briefly touch on future investigations based on dosimetry comparisons of this technique versus the more typical three day fractionation schemes (9Gy x three fractions).

Multimodality Imaging of Spinal Metastasis by Pejman JABEHDAR MARALANI, MD FRCPC, 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)

Spinal metastasis are among the most common sites of cancer metastasis. As stereotactic body radiation therapy to treat spinal metastasis is gaining popularity, precise determination and localization of spinal metastasis is of paramount importance. This lecture reviews different imaging modalities to assess spinal metastasis for both diagnosis and follow up.

MR-guided radiotherapy: a game changer or all hype? by Alison TREE, MD (Res)

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)

MR-guided radiotherapy promises to revolutionise radiotherapy delivery. These systems bring the obvious benefits of improved soft-tissue definition, and the ability to monitor anatomy with cineMRI during beam-on. However, the more fundamental innovation is the ability to deliver daily adaptive replanning while the patient is on the bed, allowing us to, for the first time, adapt our radiation plan daily to account for anatomical changes. This has great potential, particularly in the ‘hard to treat’ cancers where dose escalation has previously been limited by proximity to OARs, and the need to cover a large margin for interfraction variability. Dr Tree will share the Royal Marsden/Institute of Cancer Research experience of MR-guided radiotherapy and suggest some areas where it will improve patient care in the future.
