Anthracycline-based hepatic arterial infusion chemotherapy achieved 17 months of disease regression in a patient with breast cancer liver metastases resistant to multiple systemic chemotherapies.

Hepatic arterial infusion chemotherapy (HAIC) for liver metastases (LMs) from breast cancer is not a standard of care, but its effectiveness in patients with extensive LMs who cannot tolerate systemic therapy has been reported. Herein, we report a case of breast cancer LMs that were controlled by anthracycline-based HAIC. A 46-year-old woman with estrogen receptor-positive, human epidermal growth factor receptor 2-negative metastatic breast cancer who had multiple LMs and bone metastases underwent seven lines of systemic therapy (paclitaxel/bevacizumab for 38 months; letrozole, nivolumab/fulvestrant, eribulin, gemcitabine/vinorelbine, high-dose toremifene/abemaciclib, and capecitabine for 21 months in total).

A case of rapidly progressing sarcomatous intrahepatic cholangiocarcinoma with suddenly appearing lymph node metastasis.

Background: The sarcomatous variant of carcinoma is relatively rare in intrahepatic cholangiocarcinoma (ICC). Sarcomatous ICC (SICC) is associated with a poorer prognosis compared with ICC. SICC is rarely diagnosed before surgery due to non-descriptive findings; it progresses rapidly, resulting in miserable prognosis.

Axial torsion of Meckel's diverticulum causing acute peritonitis in the first trimester of pregnancy: a case report.

Background: Meckel's diverticulum is considered the most prevalent congenital anomaly of the gastrointestinal tract. Approximately 4% of patients are symptomatic with complications such as bleeding, intestinal obstruction, and inflammation, while axial torsion of Meckel's diverticulum is rare, particularly in pregnancy.

Case Presentation: A 31-year-old woman in week 15 of pregnancy complained of epigastric pain, nausea and vomiting.

Non-functioning pancreatic neuroendocrine tumor accompanied with multiple liver metastases: remorseful case and literature review.

Context: Pancreatic neuroendocrine tumor (P-NET) is a rare and slow-growing tumor. Unfortunately, there is no clear consensus on the role and timing of surgery for primary tumor and liver metastases, although current reports refer to liver surgery including LT for unresectable liver metastases.

Case Report: A thirty-nine-year-old man was diagnosed with nonfunctioning pancreatic neuroendocrine tumor (P-NET) in the pancreatic head, with multiple liver metastases.

A single-center analysis of the survival benefits of adjuvant gemcitabine chemotherapy for biliary tract cancer.

Background: Surgical resection is the only curative treatment of biliary tract cancer (BTC). However, the prognosis of BTC remains unsatisfactory. The aim of this study is to evaluate the benefits of adjuvant gemcitabine chemotherapy for BTC.

Effects of oral intake of hydrogen water on liver fibrogenesis in mice.

Aim: Liver fibrosis is the universal consequence of chronic liver diseases. Sustained hepatocyte injury initiates an inflammatory response, thereby activating hepatic stellate cells, the principal fibrogenic cells in the liver. Reactive oxygen species are involved in liver injury and are a promising target for treating liver fibrosis.

Effect of olprinone on liver microstructure in rat partial liver transplantation.

Background: Donor safety is a major concern in living-donor liver transplantation. However, partial grafts do not meet the functional demands of recipients and lead to small-for-size syndrome (SFSS). In a previous study, we showed that olprinone (OLP), a selective phosphodiesterase ІІІ inhibitor, up-regulates endothelial nitric oxide synthase level in the liver and attenuates shear stress, sinusoidal endothelial cell injury, and hepatocyte apoptosis after excessive liver resection in a rat model.

Sorafenib attenuates monocrotaline-induced sinusoidal obstruction syndrome in rats through suppression of JNK and MMP-9.

Background & Aims: Sinusoidal obstruction syndrome (SOS) is a drug-induced liver injury that occurs with oxaliplatin treatment and is associated with postoperative morbidity after hepatectomy. The aim of this study was to investigate the effects of sorafenib in a monocrotaline (MCT)-induced model of SOS in rats.

Methods: Rats were divided into groups treated with sorafenib (2mg/kg) or vehicle, 36 h and 12h before MCT (90 mg/kg) administration by gavage.

Downregulation of the Wnt antagonist Dkk2 links the loss of Sept4 and myofibroblastic transformation of hepatic stellate cells.

Background/aims: Sept4, a subunit of the septin cytoskeleton specifically expressed in quiescent hepatic stellate cells (HSCs), is downregulated through transdifferentiation to fibrogenic and contractile myofibroblastic cells. Since Sept4(-/-)mice are prone to liver fibrosis, we aimed to identify the unknown molecular network underlying liver fibrosis by probing the association between loss of Sept4 and accelerated transdifferentiation of HSCs.

Methods: We compared the transcriptomes of Sept4(+/+) and Sept4(-/-) HSCs undergoing transdifferentiation by DNA microarray and quantitative reverse transcription polymerase chain reaction (RT-PCR) analysis.

Proliferative activity in hepatocellular carcinoma is closely correlated with glucose metabolism but not angiogenesis.

Background & Aims: This study investigated the relationship between tumor proliferative activity and the grade of tumor glucose metabolism or angiogenesis in hepatocellular carcinoma (HCC).

Methods: The study was performed as a retrospective analysis of 63 patients with HCC who underwent fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) as a preoperative examination prior to liver resection. Tumor proliferative activity was evaluated by the Ki-67 labeling index (LI).

Olprinone attenuates excessive shear stress through up-regulation of endothelial nitric oxide synthase in a rat excessive hepatectomy model.

After extended hepatectomy, excessive shear stress in the remnant liver causes postoperative liver failure. Olprinone (OLP), a selective phosphodiesterase inhibitor, has been reported to improve microcirculation and attenuate inflammation. The aim of this study was to investigate the effects of OLP on shear stress in rats with an excessive hepatectomy (EHx) model.

Resistance to cisplatin-induced apoptosis via PI3K-dependent survivin expression in a rat hepatoma cell line.

Hepatocellular carcinoma (HCC) is known to be resistant to chemotherapy. Survivin, a member of the inhibitor of apoptosis proteins, is overexpressed in most cancers but is absent in most normal adult tissue. The aim of this study was to investigate whether expression of survivin contributes to resistance to cisplatin-induced apoptosis.

Dai-kenchu-to attenuates rat sinusoidal obstruction syndrome by inhibiting the accumulation of neutrophils in the liver.

Background And Aim: Sinusoidal obstruction syndrome (SOS) is drug-induced liver injury that occurs in patients who receive hematopoietic cell transplantation and oxaliplatin-contained chemotherapy. The aim of study was to investigate the pharmacological treatment of SOS using a traditional Japanese medicine, Dai-kenchu-to (DKT).

Methods: Male Sprague-Dawley rats were treated with monocrotaline (MCT) to induce SOS.

Inhibition of c-Jun NH2-terminal kinase switches Smad3 signaling from oncogenesis to tumor- suppression in rat hepatocellular carcinoma.

Unlabelled: Transforming growth factor beta (TGF-beta) signaling involves both tumor-suppression and oncogenesis. TGF-beta activates the TGF-beta type I receptor (TbetaRI) and c-Jun N-terminal kinase (JNK), which differentially phosphorylate the mediator Smad3 to become COOH-terminally phosphorylated Smad3 (pSmad3C) and linker-phosphorylated Smad3 (pSmad3L). TbetaRI-dependent pSmad3C transmits a tumor-suppressive TGF-beta signal, while JNK-dependent pSmad3L promotes carcinogenesis in human chronic liver disorders.

A phosphodiesterase III inhibitor protects rat liver from sinusoidal obstruction syndrome through heme oxygenase-1 induction.

Objective: The aim of study was to investigate pharmacological treatment for sinusoidal obstruction syndrome (SOS).

Background: SOS is associated with oxaliplatin-based chemotherapy in patients with hepatic colorectal metastases. Patients with SOS have increased postoperative morbidity after major hepatectomy, but a method for effective prevention of SOS has not been established.

Prophylactic respiratory management after liver resection with bilevel positive airway pressure ventilation: Report of three cases.

Pulmonary complications after hepatectomy occur with relative frequency and are associated with increased morbidity and mortality. Moreover, their prevention is often difficult. We report using prophylactic bilevel positive airway pressure ventilation, initiated just after the operation, for the successful postoperative respiratory management of three patients predisposed to the development of pulmonary complications.
