Impact of aging on hepatic reserve after preoperative portal vein embolization in hepatectomy for perihilar cholangiocarcinoma.

Purpose: In the current situation of an increasing older adult population with perihilar cholangiocarcinoma (PHCC), the benefits and risks of surgical treatment of PHCC in older people remain controversial. Portal vein embolization (PVE) is a useful preoperative procedure to improve hepatic reserve in the future remnant liver (FRL) and avoid postoperative liver failure after extended hepatectomy for PHCC. This study aimed to evaluate the influence of aging on PVE.

Enhanced Germinal Center Reactions Within Tertiary Lymphoid Structures Following Neoadjuvant Chemotherapy and Intestinal Care-A Path to Robust Antitumor Immune Response in Borderline Resectable Pancreatic Ductal Adenocarcinoma.

Background: In 2019, 4 patients with borderline resectable-pancreatic ductal adenocarcinoma(BR-PDAC)received neoadjuvant chemotherapy(NAC)with 3 cycles of gemcitabine plus nab-paclitaxel(GnP)over 12 weeks in combination with intestinal care, and subsequently underwent pancreatectomy. Surprisingly, histological response to NAC was Grade 3(viable tumor cells <10%)in 3 out of 4 patients. Aim/subjects: This study aimed to clarify the histopathological findings common to 3 patients with Grade 3 histological response to NAC.

Predictors of portal vein thrombosis after simultaneous hepatectomy and splenectomy: A single-center retrospective study.

Background: Although postoperative portal vein thrombosis (PVT) is a frequent complication of splenectomy, few studies have examined PVT after simultaneous hepatectomy and splenectomy (HS). The aim of this study was to clarify the risk factors for and characteristics of PVT after HS.

Methods: This retrospective observational study included 102 patients, including 76 with liver cirrhosis (LC) and 26 without, who underwent HS between April 2004 and April 2021.

Clinicopathological features of cholangiolocarcinoma and impact of tumor heterogeneity on prognosis: A single institution retrospective study.

Cholangiolocarcinoma (CLC) is an extremely rare tumor classified as a subtype of small duct-type intrahepatic cholangiocarcinoma (iCCA). There are few detailed reports on CLC and the prognostic impact of tumor heterogeneity is not clear. Between April 2006 and June 2022, of the 774 primary liver cancer resection cases who presented at Kanazawa University Hospital, 14 patients were pathologically diagnosed with CLC through immunohistochemical analysis of their molecular and biological features.

Morphology of the Dorsal Pancreatic Artery and Its Oncological Significance in Pancreatic Cancer.

Material And Methods: Rats were divided into NL (normal liver), SOS (monocrotaline [MCT]-treated), and SOS + CZ (MCT + CZ-treated) groups.

Hemophagocytic Lymphohistiocytosis With Elevated Cytokines Related to Macrophage Activation After Liver Transplantation for Autoimmune Hepatitis: A Case Report.

Hemophagocytic lymphohistiocytosis (HLH) is a rare but lethal complication of liver transplantation (LT). HLH is characterized by pathologic macrophage activation with hypercytokinemia, excessive inflammation, and tissue destruction, resulting in progressive organ dysfunction. HLH is also known as macrophage activation syndrome (MAS) when complicated by rheumatic or autoinflammatory diseases.

Case report: therapeutic monitoring of vancomycin in an acute liver failure patient with anuria under high-flow continuous hemodiafiltration.

Background: High-flow continuous hemodiafiltration (HF-CHDF) combines diffusive and convective solute removal and is employed for artificial liver adjuvant therapy. However, there is no report on dosage planning of vancomycin (VCM) in patients with acute liver failure under HF-CHDF.

Case Presentation: A 20-year-old woman (154 cm tall, weighing 50 kg) was transferred to the intensive care unit (ICU) with acute liver failure associated with autoimmune liver disease.

Early progression of a pancreatic metastasis of synovial sarcoma after pancreatectomy.

Background: Synovial sarcoma is a malignant tumor that constitutes up to 10% of all soft-tissue sarcomas. The most frequent metastatic sites of synovial sarcoma are the lungs, lymph nodes, and bone, whereas pancreatic metastasis is extremely rare. Here, we report a case of pancreatic metastasis of synovial sarcoma.

Thrombopoietin accumulation in hepatocytes induces a decrease in its serum levels in a sinusoidal obstruction syndrome model.

Sinusoidal obstruction syndrome (SOS) is a type of fatal hepatic injury, which predominantly occurs following exposure to drugs, such as oxaliplatin, or bone marrow transplantation. Extravasated platelet aggregation (EPA) plays an important role in the development of SOS in rat and mouse models. Furthermore, platelets invading the space of Disse adhere to hepatocytes and are phagocytized in patients with SOS.

A case of intrahepatic cholangiocarcinoma arising from a simple hepatic cyst via dysplasia and carcinomatous transformation.

We report a rare case of intrahepatic cholangiocarcinoma (iCCA) that arose from a simple hepatic cyst. A 72-year-old man was transferred to our hospital for treatment of a liver tumor. Dynamic contrast-enhanced computed tomography (CT) detected a small tumor surrounding a hepatic cyst in segment 8 that showed low attenuation on a pre-contrast CT, rim-like enhancement in the arterial dominant phase, and delayed enhancement in the delayed phase.

[Intestinal Care Using L‒Glutamine Supplement and Probiotics Can Induce a Strong Anti‒Tumor Immune Response through the Induction of Mature Tertiary Lymphoid Structures in Pancreatic Cancer Patients Receiving Preoperative Chemotherapy].

Most cancer patients receiving chemotherapy are accompanied by gut dysbiosis and intestinal mucosal barrier dysfunction to a greater or lesser degree. These disorders of the gut can easily cause bacterial translocation, resulting in the formation of immunothrombosis composed mainly of neutrophil extracellular traps and activated platelets in hepatic sinusoid in order to trap bacteria. At the same time, however, a lot of alarmin such as HMGB1, S100A8/S100A9 and VEGF‒A which are released from immunothrombosis, promote to recruit many myeloid‒derived suppressor cells(MDSCs)from bone marrow, leading to the strong immunosuppressive milieu in both liver and cancerous lesions.

Analysis of perioperative glucose metabolism using an artificial pancreas.

Hyperglycemia associated with insulin resistance is common in surgical patients with and without diabetes and is associated with poor surgical outcomes. Several studies have recently shown that a closed-loop blood glucose monitoring system in the form of an artificial pancreas is safe and effective for surgical patients. In this study, we analyzed the risk factors for insulin resistance in patients using an artificial pancreas.

A phase I study of preoperative (neoadjuvant) chemotherapy with gemcitabine plus -paclitaxel for resectable pancreatic cancer.

Neoadjuvant chemotherapy (NAC) has become a standard treatment for borderline resectable pancreatic ductal adenocarcinoma (PDAC). The present study examined the maximum tolerated dose of NAC with gemcitabine plus -paclitaxel (GnP) in patients with resectable PDAC. Between 2015 and 2019, 39 patients with resectable PDAC were enrolled in the present study.

Clinical features and diagnostic imaging of cholangiolocellular carcinoma compared with other primary liver cancers: a surgical perspective.

Background And Objectives: Although cholangiolocellular carcinoma is considered a combined hepatocellular and cholangiocarcinoma, we feel that this classification is not appropriate. Therefore, we compared the diagnostic imaging findings, surgical prognosis, and pathological features of cholangiolocellular carcinoma with those of other combined hepatocellular and cholangiocarcinoma subtypes, hepatocellular carcinoma, and cholangiocarcinoma.

Methods: The study patients included 7 with classical type combined hepatocellular and cholangiocarcinoma; 8 with stem cell feature, intermediate type combined hepatocellular and cholangiocarcinoma; 13 with cholangiolocellular carcinoma; 58 with cholangiocarcinoma; and 359 with hepatocellular carcinoma.

Platelet adherence to cancer cells promotes escape from innate immune surveillance in cancer metastasis.

The impacts of post‑operative abdominal infectious complications increase hematogenous distant metastasis and result in poor long‑term survival after curative resection. Even if curative resection can be performed, the presence of circulating tumor cells is affected. The liver, the most common site of metastases, is an important organ in innate immune surveillance.

Extravasated platelet aggregation contributes to tumor progression via the accumulation of myeloid-derived suppressor cells in gastric cancer with peritoneal metastasis.

Extravasated platelet aggregation (EPA) serves an important role in the cancer microenvironment during cancer progression, and has been demonstrated to interact with tumor cells in several types of cancer. EPA induces epithelial-mesenchymal transition (EMT) via transforming growth factor-β, and also recruits immunosuppressive cells, including regulatory T (Treg) cells and myeloid-derived suppressor cells (MDSCs). However, the role of EPA in gastric cancer with peritoneal metastasis remains unknown.

Pretreatment with a Phosphodiesterase-3 Inhibitor, Milrinone, Reduces Hepatic Ischemia-Reperfusion Injury, Minimizing Pericentral Zone-Based Liver and Small Intestinal Injury in Rats.

BACKGROUND Severe pericentral zone (zone 3)-based liver injury (LI) may become intractable, with allograft dysfunction after liver transplantation. The phosphodiesterase-3 inhibitor, milrinone, has been reported to attenuate hepatic ischemia-reperfusion injury (IRI). This study clarified how hepatic IRI involved zone 3-based LI, in which zone milrinone was effective, and whether milrinone could improve small intestinal injury (SII) with hepatic IRI.
