Abstract
Interventional Radiology (IR) procedures addressing cancer have been grouped in the subspecialty of interventional oncology and represent an important component of modern multidisciplinary cancer care. This study pinpoints temporal and geographical trends of public online searches for terms related to the field, as well as IR-related cancer therapies. Google Trends data were analyzed for long-term (2004–2020) trends in the United States and worldwide. Overall, search interest for IR increased throughout the United States but decreased globally. Specific search volumes for cancer-related IR techniques such as radioembolization and chemoembolization therapies increased by 2.8- and 2.5-fold, respectively, in the United States, whereas the search volumes for ablation techniques remained steady or decreased. Future research and advocacy may focus on increasing public awareness of the field.
