Aintained following discontinuation. The present study describes a case of recurrent HCC having a portal vein tumor thrombus (PVTT) with the third portal vein soon after resection SGLT1 Storage & Stability within a patient who was treated with sorafenib and accomplished a CR, which was then maintained for more than one particular year following the discontinuation with the medication. A literature assessment can also be presented. Written informed consent was obtained in the patient. Case report The patient was a 68-year-old male with hepatitis C virus-related liver cirrhosis. A giant HCC was detected and an S7/S8 segmentectomy on the liver was performed at a different hospital. Recurrence in the residual liver, PVTT inside the suitable portal branch and proper abdominal disseminated lesions were noted 4 months after the surgery, even though only the disseminated lesions had been surgically excised at the request on the patient. The patient was referred to Toho University Healthcare Center, Omori Hospital (Tokyo, Japan) to continue therapy for the intrahepatic recurrence. Inside the initial blood tests in the hospital, liver function was graded as Child-Pugh A and tumor marker levels had been higher: -fetoprotein (AFP), four,773 ng/Correspondenceto: Dr Manabu Watanabe, Division of Gastroenterology and Hepatology, Division of Internal Medicine, Toho University Medical Center, Omori Hospital, 6-11-1 Omorinishi, Ota-ku, Tokyo 143-8541, Japan E-mail: [email protected] Crucial words: hepatocellular carcinoma, sorafenib, completeresponse, portal vein tumor thrombusSHIOZAWA et al: Complete RESPONSE OF HEPATOCELLULAR CARCINOMA FOLLOWING SORAFENIBml; AFP-L3, 60.5 ; and des- carboxyprothrombin (DCP), 17,400 mAU/ml (Fig. 1). Abdominal computed tomography (CT) showed many tumors within the bilateral lobes as well as a PVTT inside the correct portal branch (Fig. 2). Oral sorafenib therapy was initiated at the advised dose of 800 mg/day. Grade 3 hand-foot syndrome (Common Terminology Criteria for Adverse Events version 4.0) (five) developed 7 days right after the initiation of sorafenib therapy, and the dose was lowered to 400 mg/day on day ten. Just after one particular month of administration, the AFP level was decreased to 45.7 ng/ml, but there were no adjustments in PVTT or within the many tumors in the bilateral lobes on abdominal CT. The situation was judged to become of a steady illness Caspase 8 web determined by the modified Response Evaluation Criteria in Strong Tumors (mRECIST) (6). A partial response was accomplished right after six months. On abdominal CT after two years of sorafenib administration, many tumors inside the bilateral lobes had shrunk and also the intense staining resulting from the PVTT had been resolved, determined by which the condition was judged to have accomplished a CR. Sorafenib at 400 mg/day was continued thereafter, but mild cerebellar infarction developed at two years and 4 months right after the initiation of administration, and sorafenib was withdrawn at the request in the patient. A CR was maintained for roughly one particular year soon after the discontinuation determined by abdominal CT findings and typical tumor marker levels. Discussion Sorafenib is often a multikinase inhibitor with reported activity against Raf-1, B-Raf, vascular endothelial growth issue receptor two (VEGFR2), platelet-derived development factor receptor (PDGFR) and c-Kit receptors, as well as other receptor tyrosine kinases and serine threonine kinases (7). Sorafenib can be a molecular-targeted drug that exerts an antitumor effect by inhibiting tumor growth and vascularization. The efficacy of sorafenib has been shown in the SHARP (2) and AsiaPac.
