While radiation therapy (RT) is a highly effective treatment for many solid tumors, thoracic RT carries a risk of cardiovascular (CV) morbidity and mortality that limits critical gains in cancer control and survival.

Ongoing advances in technology have allowed for the shrinkage of target volumes and lowering of doses in the treatment of lymphomas with radiation.

Several national societies' guidelines, including the National Comprehensive Cancer Network and the American Society of Clinical Oncology, recommend screening of older adults with cancer with a comprehensive geriatric assessment (CGA) or similar tools.

The role of RT in DLBCL is changing. Recent randomized studies have challenged the role of RT in the primary treatment of DLBCL but they included selected patient populations, making application of results in routine clinical practice difficult.

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.

Adaptive radiotherapy is emerging as a treatment approach for patients with improvements in technology that allow real-time planning and consequent treatment delivery. Different imaging modalities are used, such as MR and CBCT, for image guidance.

Online adaptive radiotherapy (ART) is a current and emerging technology and approach that leverages CT and MR images obtained on the treatment delivery platform to personalized daily RT fractions to account for organ and tumor motion, deformation, and positioning with the potential of improving o
