title: Giant cavernous hepatic hemangioma shrunk by use of sorafenib.
abstract: Here we report a case of a 76-year-old man with a giant cavernous hepatic hemangioma of more than 20 cm in diameter. Since the hepatic hemangioma was actually growing and might possibly rupture and he complained of abdominal symptoms, we decided to perform interventional therapy. First we performed transcatheter arterial embolization (TAE) of the hepatic arteries. However, since this was not sufficiently effective, we added sorafenib (600 mg/day). As a result, the tumor shrank with symptomatic improvement. Subsequently, an adverse event occurred, and we suspended the sorafenib therapy. Then, the tumor began to grow, and we resumed administering sorafenib at 400 mg/day. The tumor shrank again, and we continued the sorafenib therapy thereafter. The tumor shrinkage, although possibly induced by the effect of TAE, is considered primarily due to the effect of treatment with sorafenib, because (1) TAE did not sufficiently reduce the blood supply to the inside of the tumor; (2) other tumors shrank in the area not targeted by TAE; and (3) the tumor grew during suspension of sorafenib therapy and shrank again after resuming the treatment.
