A Case of Unresectable Pancreatic Cancer with Long-Term Survival in High-Intensity Focused Ultrasound (HIFU) Therapy

摘要

Despite advancements in imaging diagnosis, about 60% of cases of pancreatic cancer (PC) are still unresectable. Chemotherapy and radiochemotherapy are commonly performed as alternative treatments, but satisfaction with the results remains low. High intensity focused ultrasound therapy (HIFU) is expected to be a minimally invasive therapy for these cases. HIFU is an epoch-making therapeutic method and is a local therapy that converges a large number of ultrasonic transmission sources at one point at the target site of the tumor and cauterizes tissues from outside the body .
