Research progress on hippocampal-avoidance whole brain radiotherapy / 中华放射肿瘤学杂志

ABSTRACT

With the advancement of imaging diagnosis and the development of modern radiotherapy, the survival of cancer patients has been prolonged and the incidence rate of brain metastases (BM) has been significantly increased. The quality of life of patients and potential radiotherapy-induced neurocognitive impairment have gradually captivated widespread attention. Whole brain radiotherapy (WBRT) is one of the common local therapies for BM patients. However, the application of WBRT is controversial because it may lead to neurocognitive impairment. The incidence of metastatic tumors in hippocampus and radiation-induced neurocognitive impairment can accelerate the implementation of hippocampal-avoidance WBRT (HA-WBRT). In this article, the feasibility of HA-WBRT was discussed and research progress in recent years was reviewed.
