HyTEC (Hypo-fractionated or “Hy”-dose per fraction, Treatment Effects in the Clinic) was an American Association of Physicists in Medicine-led initiative focusing on hypofractionated SBRT/SABR and stereotactic radiosurgery in adults.

This session highlights the most clinically relevant abstracts within the Central Nervous System track of the 2023 ASTRO Annual Meeting scientific program.

This session will focus on recent and emerging research in radiation oncology for patients with brain and spine tumors. Special emphasis will be placed on radiosurgery dose/fractionation selection, IDH inhibition in glioma and glioma contouring/targeting.

There have been many advances and evolutions in the treatment of primary and metastatic CNS tumors. There are different treatment planning and contouring guidelines for CNS tumors. Without a clear and consolidated understanding of best practices, this could affect quality of care.

The field of cancer is a rapidly evolving field with new treatment approaches moving to clinic on a daily basis. Radiation Oncology is no different. It is extremely difficult for a practicing clinician to stay abreast of new developments in cancer care.

Optimal management of leptomeningeal disease with radiation therapy is an active area of interest.

This panel session is the first ASTRO session dedicated to leptomeningeal disease in cancer. This is a case-based session with experts in neuroimaging, neuro-oncology, medical oncology, radiation oncology, as well as a patient speaker with LM disease who share their perspective.

Recent publications have established SBRT as the standard of care in painful spine metastases. As a result, spine SBRT is being increasingly utilized in both academic and community practices, rendering this educational activity timely.

The present study provides expert consensus recommendations for management of steroid refractory symptomatic radiation necrosis in patients treated with SRS.
