Palliative radiotherapy is frequently applied for various indications, with hemostasis being a quite common one. However, while bleeding can occur at different sites and arise from various primary tumor types, clear guidelines for administering hemostatic radiotherapy are lacking. Additionally, most available data on hemostatic radiotherapy are retrospective, and often studies do not focus on hemostasis specifically. This review provides an overview of the most recent data on hemostatic radiotherapy to identify any research trends and focus areas for this specific topic. This review confirms the value of radiation for tumor bleeding. Unfortunately, research in hemostatic radiotherapy predominantly continues to focus on retrospective analyses of treated patients. However, at least two prospective trials specifically investigating hemostasis have been published recently, both conducted in low-income countries. Radiotherapy is an effective and well-tolerated treatment for bleeding tumors. As the incidence of advanced cancer rises in low- and middle-income countries, where resources are limited, further research should focus on hypofractionated regimens. Additionally, there is a need for comprehensive descriptions of contouring and treatment planning to optimize outcomes in these settings.
