On April 21, 2026, the Georgian Health Physics Association hosted an online meeting featuring a presentation by Davit Sebua, Medical Physicist at the Radiation Medicine Centre, Chief Specialist at the Institute of Physics (Nuclear Department), and a certified radiation safety specialist.
The presentation addressed the role of palliative radiotherapy in oncology, with a particular focus on its application in the management of bone metastases. Emphasis was placed on pain relief and preservation of functional capacity as primary clinical objectives in palliative care.
Drawing on a series of treated patient cases, the work examined outcomes associated with different dosimetric regimens, evaluated using biologically effective dose (BED) and equivalent dose in 2 Gy fractions (EQD2). The analysis demonstrated that appropriately selected fractionation schemes can provide both rapid and sustained symptom relief while maintaining a favorable side effect profile.
The findings presented support the conclusion that, in the context of bone metastases, palliative radiotherapy remains an effective approach not only for symptom control but also for improving patient quality of life. The presentation was followed by an engaging discussion among participants, addressing clinical considerations and practical aspects of treatment optimization.
This meeting reflects GHPA’s continued commitment to fostering professional exchange on topics at the intersection of medical physics, radiation safety, and clinical practice.
