ABSTRACT
BACKGROUND: Metastasis occurs as a late event in the natural history of hepatocellular carcinoma (HCC), and most patients die of liver failure attributed to the tumor supplanting the liver. Conversely, the brain is a less common metastatic site. CASE SUMMARY: We describe a rare case of hepatitis C virus-related multiple HCC metastasizing to the cavernous sinus, Meckel's cave, and the petrous bone involving multiple cranial nerves in an 82-year-old woman. At admission imaging studies including Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (MRI) revealed multiple HCC nodules in both right and left lobes. Ultrasound guided biopsy of the left lobe revealed moderately differentiated HCC. Molecular targeted therapy with Lenvatinib (8 mg/d for 94 d, per os) and Ramucirumab (340 mg/d and 320 mg/d, two times by intravenous injection) were administered for 4 mo, resulting in progression of the disease. Three months after the start of molecular target therapy, the patient presented with symptoms of hyperalgesia of the right face and limited abduction of the right eye, indicating disturbances in the right trigeminal and abducens nerves. Brain MRI disclosed a mass involving the cavernous sinus, Meckel's cave and the petrous bone. Contrast-enhanced MRI with gadolinium-chelated contrast medium revealed a well-defined mass with abnormal enhancement around the right cavernous sinus and the right Meckel's cave. CONCLUSION: The diagnosis of metastatic HCC to the cavernous sinus, Meckel's cave, and the petrous bone was made based on neurological findings and imaging studies including MRI, but not on histological examinations. Further studies may provide insights into various methods for diagnosing HCC metastasizing to the craniospinal area.
ABSTRACT
BACKGROUND: Sofosbuvir plus ribavirin (RBV) therapy showed higher sustained virological response at 12 weeks after treatment (SVR12) than pegylated interferon (peg-IFN) plus RBV; however, liver function, fibrosis, and hepatocellular carcinoma markers have not been assessed so far. SUMMARY: Patients (n = 21) receiving Sofosbuvir plus RBV and those (n = 24) receiving peg-IFN plus RBV were enrolled in this study. Changes in alanine aminotransferase (ALT) and α-fetoprotein (AFP) levels, platelet (PLT) counts, FIB-4, and aspartate aminotransferase-to-platelet ratio index (APRI) in both groups were assessed in patients achieving SVR12. Also, fibrosis regression was assessed using pathophysiological biomarkers, such as hyaluronic acid, bone morphogenetic protein 7 (BMP-7), and connective tissue growth factor (CTGF) in the Sofosbuvir plus RBV group. In both groups, while the reduction in ALT levels was significant that of AFP was not. Compared with the baseline, although serum PLT count at the end of treatment (EOT) was significantly higher in the Sofosbuvir plus RBV group, it was significantly lower in the peg-IFN plus RBV group. Although a significant decline in fibrosis markers such as FIB-4 and APRI was observed between the baseline and at EOT in the Sofosbuvir plus RBV group, no significant change of these markers was observed in the peg-IFN plus RBV group. Moreover, BMP-7 and CTGF were significantly lower at EOT than the baseline in the Sofosbuvir plus RBV group. Key Message: The treatment with Sofosbuvir plus RBV results in not only a higher SVR, but also improves the liver function and the degree of fibrosis.
