RESUMO
An 80-year-old Japanese man presented to our hospital with intra-abdominal hemorrhage due to a ruptured liver tumor. Transcatheter arterial embolization (TAE) temporarily achieved hemostasis, but he died following re-rupture 4 days later. Based on autopsy findings, the liver tumor was diagnosed as hepatic angiosarcoma. Embolic agents used during embolization were identified within the hepatic small interlobular arteries. However, there were no findings of tumor cell necrosis or ischemic change in the angiosarcoma. In the present case, TAE alone did not induce ischemia-induced tumor necrosis, suggesting that TAE might be unsuitable to treat hepatic angiosarcoma. Treatment optimization for ruptured hepatic angiosarcoma is desired.
RESUMO
The increased use of immune-checkpoint inhibitors to treat various types of cancer has increased the incidence of immune-related adverse events (irAEs). Hepatic irAEs are frequent and can lead to serious conditions. Among the various types of hepatic irAEs reported to date, bile duct injury has been shown refractory to steroid treatment. This study describes 2 patients with hepatic irAEs manifesting as intrahepatic bile duct injury. Immunostaining with antibodies to both CD8 and cytokeratin-7 was useful for the diagnosis, and both patients were refractory to steroid treatment. Prompt diagnosis and active immunosuppressive therapies are required in such cases.
RESUMO
PURPOSE: To evaluate the potential of drug-eluting bead (DEB)-transcatheter arterial chemoembolization (TACE) as a treatment option for patients with refractory to conventional lipiodol-based TACE (c-TACE) especially with decreased liver function. PATIENTS AND METHODS: We retrospectively evaluated the treatment results of DEB-TACE for 89 HCC nodules in 27 patients with c-TACE refractory according to liver function. RESULTS: Although overall survival was significantly better in Child-Pugh A patients than in Child-Pugh B patients (median survival time, MST: 561 vs 347 days, p=0.031), progression-free survival was almost similar in both patients between Child-Pugh A and B (MST: 79 vs 87 days, p=0.534). Regarding antitumor response, the objective response rate (ORR) and disease-control rate (DCR) were 5.3/12.5% and 52.7/87.5% in Child-Pugh A/B, respectively. In each 89 HCC nodules, ORR and DCR were almost similar between Child-Pugh A and B (ORR, 20.3 vs 13.3%; DCR, 77.0 vs 73.3%, respectively). Adverse events of DEB-TACE were well-tolerated, and liver function was reserved during DEB-TACE procedures. CONCLUSION: DEB-TACE could be a therapeutic option for advanced HCC patients with c-TACE refractory and decreased liver function.
RESUMO
Lenvatinib is a first-line standard treatment for advanced hepatocellular carcinoma (HCC) with better anti-tumor effects than sorafenib, as shown by greater inhibition of the kinases of fibroblast growth factor receptor and vascular endothelial growth factor (VEGF) receptor. This report describes a patient with advanced HCC who experienced perforation of the small intestine 1 month after starting the treatment with lenvatinib. This patient likely had partial necrosis of a metastasis to the small intestine before starting lenvatinib treatment, with subsequent ischemic changes leading to perforation of the small intestine. Although metastasis of HCC to the small intestine is rare, patients with these metastases should be regarded as being at risk for perforation during lenvatinib treatment.
