AbstractAbstract PDF
In patients with hepatocellular carcinoma (HCC) or liver cirrhosis (LC) accompanied by hepatitis E virus (HEV) infection, hepatic failure often leads to debility. Here, we report about a 63-year-old man with alcoholic LC who was referred to our hospital with jaundice and abdominal distension 10 days earlier. Abdominal computed tomography showed necrotic HCC accompanied by left lobe shrinkage without tumor progression. Laboratory and imaging findings revealed no acute infection focus. The patient reported no herbal medicine or alcohol consumption, and there was no evidence of acute viral hepatitis. One month later, HEV immunoglobulin M positivity was confirmed, and deterioration of liver function due to HEV infection was suspected. The patient often ate raw oysters and sashimi, as well as boar meat, which is a well-known risk food for HEV infection. His umbilical hernia deteriorated due to tense ascites and infection by skin abrasion. The patient progressed to hepatorenal syndrome and eventually died. Liver function preservation is important when treating HCC patients. Therefore, clinicians should pay more attention to the prevention of HEV and others causes of direct liver injury.

AbstractAbstract PDF
Spontaneous regression of hepatocellular carcinoma (HCC) is associated with alcohol abstinence, herbal medication, radiation, ischemia and immune reaction against systemic or local infections. Herein, we report a case of 67-year-old man with spontaneous disappearance of HCC after local infection as a rare cause. The patient had no clinical symptoms except for markedly increased tumor marker of HCC (protein induced by vitamin K absence or antagonist-II: 731 mAU/mL). On computed tomography (CT) and magnetic resonance imaging, massive infiltrating HCC with portal vein invasion was confirmed. During conservative treatment, he was admitted due to suppurative diabetic foot. After medical treatment, HCC disappeared on follow-up CT scans, along with change in hepatic contour. The disappearance of HCC might be a result of immune response by treatment of the diabetic foot and that of ischemia by portal vein tumor thrombosis secondarily. We summarized case reports regarding spontaneous regression of HCC by infection and ischemia.

AbstractAbstract PDF
Hepatocellular carcinoma (HCC) is the most common form of liver malignancy. Spontaneous regression of HCC is extremely rare phenomenon and mechanism of regression remains obscure. 75-year-old woman previously diagnosed with hepatitis C virus-related liver cirrhosis was found to have single mass in liver with elevation of α-fetoprotein level to 10,320 ng/mL. Transarterial chemoembolization (TACE) was performed. 27 months after TACE recurred HCC with multiple lung nodules were confirmed. The patient refused any therapeutic modality. The patient underwent follow-up without any anti-cancer treatment. 8 months after recurrence follow up computed tomography scan revealed spontaneous regression of HCC and completely disappeared lung nodules. The patient is currently doing well and without any evidence of recurrence. The causes of spontaneous regression of HCC are not well understood. Proposed mechanisms are ischemic injury, biological factors, herbal medicine, immunological variations. Further studies are necessary to improve our understanding of this rare phenomenon.
