We report a 46-year-old male patient with functional liver damage due to hepatitis B virus infection. A 12 cm hepatocellular carcinoma (HCC) in the left lobe and portal venous tumor thrombosis (PVTT) with vp4 (portal vein tumor thrombosis in the main trunk) were detected by computed tomography (CT). He underwent hepatic arterial infusion chemotherapy (HAIC) with cisplatin 100 mg for HCC and received radiation therapy (39 Gy/13 Fr) for PVTT with vp4. Follow-up CT showed reduction of HCC and reduced PVTT volume after 1 month of treatment. He then initiated lenvatinib therapy at 12 mg/day. One month later, follow-up CT showed no change in HCC size and a reduction in PVTT volume. Two months after initiating lenvatinib, follow-up CT showed no change in HCC, but further reduction in contrast effect and volume of PVTT. Three months after HAIC, he underwent drug-eluting-bead transcatheter arterial chemoembolization (DEB-TACE) with 100 mg of cisplatin (CDDP) for the HCC. After DEB-TACE, he received 12 mg/day with 5-days-on/2-days-off due to vomiting. One month after DEB-TACE, blood evaluation showed decreased tumor markers, and CT revealed that the HCC had grown slightly with no change in PVTT. Five months after HAIC, he underwent DEB-TACE with 100 mg of cisplatin for the HCC. A total of 150 days have passed since the start of lenvatinib treatment, and his Child-Pugh A status has been maintained.

A 76-year-old man was diagnosed with multiple hepatocellular carcinomas (HCCs). He underwent right lobectomy and partial resection of the liver after transcatheter arterial embolization at our hospital. The pathology report was moderately differentiated HCC (fT4N0M0 Stage Iva, Vp1, Vv0). Follow-up CT revealed a lesion in the right ventricle 3 years after surgery. Moderately differentiated HCC was determined on myocardial biopsy, and the lesion was diagnosed as cardiac metastasis of HCC. No recurrence of HCC was observed in the liver. Radiation therapy (39 Gy/13 fr) was performed for the cardiac metastasis, and oral lenvatinib 8 mg/day was started. Evaluation by mRECIST on contrast-enhanced CT indicate a partial response (PR). Lenvatinib has been continued for 7 months. Cardiac metastasis of HCC is extremely rare; herein, we have also provided a literature reviews.

This study investigated time-course changes in skeletal muscle volume per year with tolvaptan in patients with refractory ascites that was unresponsive to loop diuretics and aldosterone antagonists. This retrospective study included 42 patients who received tolvaptan for refractory ascites and/or hepatic edema and underwent computed tomography (CT) before and ≥ 3 months after initiating tolvaptan. The time-course changes in skeletal muscle index per year [ΔSMI (%)] was calculated as follows: ΔSMI (%) = (SMI at final CT scan − SMI at initial CT scan)/SMI at initial CT scan × 100/years between CT scans. Eligible patients were 23 men and 19 women of median age of 71 years (range 21–94 years). The median follow-up period was 22.7 (range 3.5–54.6) months. ΔSMI (%) was significantly higher in the responders group than in the nonresponder group. Multivariate analysis showed the response to tolvaptan was an independent and significant factor associated with an increase in muscle mass [odds ratio (OR) 20.364; 95% CI 2.327–178.97; P = 0.006]. Overall survival with tolvaptan was significantly higher in the responder group than in the nonresponder group. Multivariate analysis showed that the response to tolvaptan treatment was a significant contributor to good prognosis (OR 3.884; 95% CI 1.264–11.931; P = 0.018). A significant negative correlation was observed between the dosage of furosemide and ΔSMI (%) (P = 0.014). Treatment of refractory ascites with tolvaptan may attenuate the progression of sarcopenia and improve the prognosis in patients with decompensated cirrhosis.

We report a 74-year-old male patient with compensated cirrhosis after hepatic C virus eradication. After the patient underwent hepatectomy for hepatocellular carcinoma, multiple lung and lymph node metastases were detected by computed tomography. Computed tomography also revealed a portosystemic shunt from the superior mesenteric vein to the right testicular vein. He was administered lenvatinib (12 mg). Five days after the initiation of lenvatinib, he developed grade 3 hepatic encephalopathy, and his ammonia level increased. Lenvatinib was stopped, with improvement of the encephalopathy and decrease in ammonia level. When lenvatinib was restarted, grade 2 encephalopathy recurred which then improved upon stopping the drug. We thought that the encephalopathy was due to the portosystemic shunt, and occlusion of the shunt was performed. The day after shunt occlusion, lenvatinib (8 mg) was restarted, and the lenvatinib dose was increased to 12 mg at 2 days after shunt occlusion. Subsequently, the ammonia level remained stable and the patient remained alert and conscious. Lenvatinib was continued until the time of this report (40 days after shunt occlusion), and after 1 month of lenvatinib therapy, the computed tomography verified absence of the portosystemic shunt and stable disease of hepatocellular carcinoma.

Highlights • A lymphoepithelial cyst (LEC) of the pancreas is a benign and rare lesion. • A pancreatic LEC is difficult to be diagnosed and differentiate from the malignancy preoperatively. • We summarized the imaging features of pancreatic cysts to differentiate from the malignancy., Introduction A lymphoepithelial cyst (LEC) of the pancreas is a benign and rare lesion that is difficult to diagnose preoperatively based on imaging studies. Presentation of case We report a case of a 49-year-old man who presented with weight loss and diarrhea. The serum carcinoembryonic antigen and carbohydrate antigen 19-9 levels were slightly elevated to 6.7 ng/mL (reference value

Aim: This study investigated early tumor marker response and treatment response in patients with advanced hepatocellular carcinoma (HCC) treated with lenvatinib. Methods: Twenty patients with advanced HCC who received lenvatinib were enrolled in this retrospective study. α-Fetoprotein (AFP) and des-γ-carboxyprothrombin (DCP) levels were measured before treatment as well as 2 and 4 weeks after treatment. The objective response rate was evaluated by mRECIST at 6 weeks. Results: The response rate was 30% (complete response/partial response/stable disease/progressive disease: n = 0/6/6/8 cases) by mRECIST. At 4 weeks, the AFP levels of 12 patients (80%) were lower than at baseline. The AFP levels of 9 patients (60%) continued decreasing from 2 weeks to 4 weeks (sustained-reduction group). In this group, the response rate was 67%. The median AFP change rate was –39% at 4 weeks. In imaging responders, the AFP change rate significantly decreased (p = 0.02). The DCP change rate had no significant correlation with imaging response. The AFP-sustained-reduction group had significantly higher adherence to lenvatinib than the non-sustained-reduction group (p = 0.02). Conclusion: With lenvatinib therapy for HCC, the AFP levels of most patients had declined at 2 weeks, and at 4 weeks the AFP-sustained-reduction group demonstrated a higher objective response.

A step-up approach and continuous drainage using NPWT was an effective strategy for the treatment of severe necrotizing pancreatitis. A 62-year-old woman developed severe necrotizing pancreatitis after endoscopic retrograde cholangiopancreatography, extending from the left anterior pararenal space to the interior renal pole. Endoscopic transluminal drainage and percutaneous catheter drainage were unsuccessful in controlling the disease. We proceeded with video-assisted retroperitoneal necrosectomy, at the pancreas and splenic hilum, and drainage, with two additional surgical drains located at the left inferior renal pole and, subcutaneously, at the incision wound. NPWT enhanced fluid drainage and facilitated surgical wound closure, which was infected and opened. Four subsequent endoscopic necrosectomy procedures were required, at the site of the draining fistula, to achieve complete resolution of fluid collection and wound closure.

Purpose In recent years, it has been reported that use of 18F-FDG PET-CT can reveal the degree of hepatocellular carcinoma malignancy. We evaluate the ability of a preoperative 18F-FDG PET-CT to predict the recurrence of extrahepatic metastasis of HCC after surgery. Methods We retrospectively examined 67 patients who received 18F-FDG PET-CT prior to curative hepatic resection for HCC between April 2010 and March 2016. Multivariate Cox regression analysis was performed to identify the factors associated with recurrence of extrahepatic metastasis of HCC after surgery. We also evaluated the sensitivity, specifity, positive predictive value, negative predictive value and accuracy of diagnosis of 18F-FDG PET-CT for recurrent extrahepatic metastasis of HCC after surgery. Results The multivariate analysis identified a tumor-to-normal liver standardized uptake value ratio (TNR) ≥ 1.53 (hazard ratio [HR], 0.037; P = 0.003), multiple tumor nodules (HR, 0.121; P = 0.007), and presence of microvascular invasion (HR, 0.094; P = 0.003) as independent predictors of distant metastasis recurrence. A TNR ≥ 1.53 showed a sensitivity of 91.7 %, specificity of 76.4 %, positive predictive value of 45.8 %, negative predictive value of 97.7 %, and accuracy of 79.1 % for diagnosing distant metastasis recurrence of HCC. In a binomial logistic regression analysis of tumor factors associated with a TNR ≥ 1.53, poor tumor differentiation and large tumor size were significant factors. Conclusion 18F-FDG PET-CT and microvascular invasion may be useful for predicting the recurrence of extrahepatic metastasis of HCC after surgery., アクセプト後にアブストラクトに変更あり

We aimed to investigate the early changes in ammonia levels and liver function in patients with advanced hepatocellular carcinoma treated with lenvatinib. This retrospective study included 23 patients with advanced hepatocellular carcinoma who were able to receive lenvatinib continuously for at least 1 week. We compared their ammonia levels (NH3), total bilirubin (Bil), albumin, and prothrombin (PT) activity at before and after 1 week of lenvatinib administration, and additionally, compared the 2 groups which were divided based on the presence/absence of portosystemic collaterals (PSCs). Before administration of lenvatinib the patients with PSCs had significantly worse ammonia levels and liver function than the patients without PSCs (NH3: P = 0.013, Bil: P = 0.004, PT: P = 0.047, respectively). Moreover, the indices were worse in all the patients after 1 week of lenvatinib than before administration (NH3: P = 0.001, Bil: P = 0.025, PT: P

Introduction: The measurement of body composition such as the skeletal muscle index (SMI) has been reported to be useful for predicting prognosis in hepatocellular carcinoma (HCC). In this study, we analyzed skeletal muscle change during sorafenib and lenvatinib therapy and the association between SMI and prognosis. Methods: A total of 67 patients with advanced HCC and Child-Pugh grade A status treated with tyrosine kinase inhibitors (TKIs) at Hiroshima University between September 2009 and December 2018 were enrolled in this retrospective cohort study. Patients underwent computed tomography (CT) imaging before starting sorafenib treatment and 1–3 months after treatment initiation. Results: In all patients, the median SMI was 45.3 cm2/m2 before TKI treatment and 42.1 cm2/m2 after treatment; 54 of 67 (80.6%) patients experienced SMI loss. The median ΔSMI was –1.5 cm2/m2/months, and no difference in ΔSMI was observed between patients receiving sorafenib and lenvatinib. No significant differences were observed in median ΔSMI between patients with and without progressive disease (–2.35 and –1.1 cm2/m2/months, respectively), albumin-bilirubin grade 1 and 2 group disease (–1.7 and –1.5 cm2/m2/months, respectively), and relative dose intensity ≤80 and >80 (–1.8 and –1.2 cm2/m2/months, respectively). Conclusion: This report demonstrated that patients receiving TKI treatment experienced a significant loss of skeletal muscle mass regardless of disease progression, hepatic reserve, or which TKI (sorafenib or lenvatinib) they received.
