About SPRO

Radiation therapy is well known to provide palliation for a variety of localized cancer symptoms, which can improve patient quality of life and reduce caregiver burden and stressors. Palliative radiation therapy plays critical roles in the management of pain from bone metastases, neurological symptoms from brain metastases or spinal cord compression, and local symptoms caused by tumor compression, mass effect, or local invasion. The importance of palliative radiotherapy to end-of-life oncology care has led to International Consensus Conferences on Palliative Radiotherapy in New York in 1990, London in 2000, San Diego in 2010, and most recently Barcelona in 2015. The success and momentum of these meetings, as well as the increasing collaboration between colleagues worldwide dedicated specifically to the subspecialty of palliative radiotherapy led to the formation of the Society of Palliative Radiation Oncology (SPRO) in 2014.
SPRO is a professional society that functions as the local, national, and international levels to promote excellence in palliative radiation oncology care. This includes the provision of evidence-based palliative radiotherapy that is effective, efficient, safe, and affordable, as well as the provision of high-quality primary palliative care from the time of an advanced cancer diagnosis. We strive to advance palliative radiation oncology care through research, education, collaboration, and patient advocacy.
