Safety and feasibility of liver resection including major hepatectomy for geriatric patients with hepatocellular carcinoma: a retrospective observational study.

Background: It is unclear whether hepatectomy, which ranges in invasiveness from partial to major hepatectomy, is safe and feasible for older adult patients. Therefore, we compared its postoperative complications and long-term outcomes between younger and older adult patients.

Methods: Patients who underwent hepatectomies for hepatocellular carcinoma (N = 883) were evaluated.

Simplified and Optimized Immune Score for Colorectal Cancer Microenvironment.

Background/aim: Immunoscore (IS) is an important evaluation method for the tumor immune microenvironment (TIME); however, formal IS analysis requires designated reagents and a specific digital pathology software and image data analysis. This study aimed to investigate whether simplified IS (s-IS) can substitute formal IS upon modifying the location of the assessment of the numbers of immune cells and verify that the addition of T cell subset markers to s-IS can enhance the prognostic impact in patients with colorectal cancer (CRC).

Patients And Methods: A total of 82 CRC cases were included in this study.

Predictive and Prognostic Value of SUOX Expression in Pancreatic Ductal Adenocarcinoma.

Background/aim: Sulphite oxidase (SUOX) is a metalloenzyme that catalyses ATP synthesis via oxidative phosphorylation in the mitochondria. Although SUOX has been reported to affect the invasiveness and differentiation of cancer cells, its clinicopathological significance in pancreatic adenocarcinoma (PDAC) remains unclear. In this study, we investigated the utility of SUOX expression as a prognostic factor in PDAC.

Asymptomatic Fungemia Due to Rhodotorula spp. Caused by a Subcutaneously Implanted Central Venous Port Catheter.

A 66-year-old man was admitted to our hospital for gastrointestinal perforation. He had a history of surgery and chemotherapy for colorectal cancer and had a subcutaneously implanted central venous port catheter. After surgery for gastrointestinal tract perforation, he developed an intra-abdominal abscess, which was treated with broad-spectrum antimicrobial agents and improved.

Current Status and Problems of Breast Cancer Treatment with Schizophrenia.

Background: Schizophrenia is a devastating mental disease that affects approximately 1% of the world's population. Breast cancer is the second most common type of cancer in the world that causes death in women. It is often unclear whether patients with schizophrenia receive recommended cancer treatment that met the guideline.

Granulocyte-colony stimulating factor-producing malignant phyllodes tumor of the breast: a rare case.

Background: Granulocyte-colony stimulating factor (G-CSF)-producing tumors can cause leukocytosis despite an absence of infection. G-CSF-producing tumors have been reported in various organs such as the lung, esophagus, and stomach but rarely in the breast. We report a case of G-CSF-producing malignant phyllodes tumor of the breast.

Regional education on endoscopic surgery using a teleconference system with high-quality video via the internet: Saga surgical videoconferences.

Background: Effective education about endoscopic surgery (ES) is greatly needed for unskilled surgeons, especially at low-volume institutions, to maintain the safety of patients. We have tried to establish the remote educational system using videoconference system through the internet for education about ES to surgeons belonging to affiliate institutions. The aim of this manuscript was to report the potential to establish a comfortable remote educational system and to debate its advantages.

A rare case of symptomatic grossly-visible biliary intraepithelial neoplasia mimicking cholangiocarcinoma.

Background: Biliary intraepithelial neoplasia (BilIN) is often distinguished by what it is not: the precancerous lesions are not mass-forming, are not the cause of bile duct obstruction, and are small enough (less than 5 mm long) to evade detection by the naked eye. Here, we describe an atypical case of BilIN resembling cholangiocarcinoma (CC) that was large enough to be identified by diagnostic imaging and presented with obstructive jaundice caused by a hematoma in the common bile duct (CBD).

Case Presentation: A 64-year-old man presented to our hospital with upper abdominal pain and anorexia.

Immunological consequences following splenectomy in patients with liver cirrhosis.

The immune status in patients with liver cirrhosis is generally impaired due to concomitant hypersplenism. As the spleen is the largest lymphoid organ, deleterious events resulting from splenectomy are of concern in these patients. However, the immunological consequences after splenectomy have not yet been fully elucidated.

Retroperitoneal dedifferentiated liposarcoma with huge cystic degeneration: A case report.

Prominent cyst formation is an unusual feature of liposarcoma. We report here a case of dedifferentiated liposarcoma with huge cystic change without preoperative chemo- or radiation therapy. The lesion arose in the retroperitoneum juxtaposed to the right kidney of a 67-year-old woman.

Therapeutic efficacy of splenectomy is attenuated by necroinflammation of the liver in patients with liver cirrhosis.

Background: Splenectomy is a therapy for thrombocytopenia caused by hypersplenism with liver cirrhosis. However, the determinant of therapeutic outcomes for this complication has not yet been fully clarified.

Methods: We studied the laboratory findings of 55 patients who underwent splenectomy for hypersplenism with liver cirrhosis.

Infantile hemangioma of the liver in an adult: a case report and review of the literature.

Infantile hemangioma (IH), a representative vascular liver tumor, usually occurs in infancy or early childhood but rarely in adults. In this study, we describe a case of IH in a 47-year-old female and we also review the literature. A plain computed tomography (CT) image revealed five hypoattenuating masses in the liver.

Perioperative challenges and surgical treatment of large simple, and infectious liver cyst - a 12-year experience.

Background: Cystic lesions of the liver consist of a heterogeneous group of disorders that can present diagnostic and therapeutic challenges.

Methods: A retrospective review of all medical records of adult patients diagnosed with large (>7 cm) cystic lesions of the liver between January 2000 and December 2011, at Kurume University Hospital. Cases with polycystic disease were excluded.

Long-term outcome of splenectomy in advanced cirrhotic patients with hepatocellular carcinoma and thrombocytopenia.

Splenectomy may be a treatment option in hepatocellular carcinoma (HCC) and cirrhosis when there is no potential donor for liver transplantation. We retrospectively investigated the long-term outcome of splenectomy on survival in advanced cirrhotic patients with HCC and thrombocytopenia. Between 1999 and 2009, 46 cirrhotic patients with thrombocytopenia (Child-Pugh class B or C) who underwent splenectomy for the simultaneous or secondary treatment of HCC at our institute were evaluated.

[Laparoscopic radiofrequency ablation for hepatocellular carcinoma].

We examined the case of laparoscopic radiofrequency ablation (L-RFA) to hepatocellular carcinoma (HCC), and then the method of this treatment was considered in terms of selection and adjustment. Between January 2008 and May 2010, L-RFC was performed on 18 cases (27 tumors). A total operation time was 203 minutes (± 85.

Comparison of liver regeneration after a splenectomy and splenic artery ligation in a dimethylnitrosamine-induced cirrhotic rat model.

Aim: A splenectomy and splenic artery ligation accelerate liver regeneration and improve liver function after a hepatectomy. However, there are no studies that directly compared the effects of a splenectomy and splenic artery ligation. In the present study, we compared the effects of a splenectomy and splenic artery ligation in cirrhotic rats.

Spontaneous rupture of the spleen caused by a Bacillus infection: report of a case.

We report a case of spontaneous splenic rupture (SSR) caused by a Bacillus species (sp.) infection. A 36-year-old man on warfarin therapy since an aortic valve replacement at the age of 13 was admitted to our hospital with a 3-week history of a high fever.

A novel tumor necrosis factor-alpha suppressant, ONO-SM362, prevents liver failure and promotes liver regeneration after extensive hepatectomy.

Background: Tumor necrosis factor (TNF)-alpha is a cytokine that initiates liver regeneration after hepatectomy (HTx), although extensive HTx can cause liver failure with significant rise in serum TNF-alpha levels. To test our hypothesis that modulation of endogenous TNF-alpha attenuates liver failure even after extensive HTx, we used ONO-SM362, a novel TNF-alpha inhibitor, in mice subjected to 85% HTx.

Methods: ICR mice were divided into 5 groups: 70% HTx, 85% HTx, 85% HTx plus ONO-SM362, 85% HTx plus monoclonal TNF-alpha antibody (mAb), and 85% HTx plus FR167653, a TNF-alpha inhibitor.

Significance of thymidylate synthase gene expression level in patients with adenocarcinoma of the lung.

Background: Thymidylate synthase (TS) catalyzes the methylation of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP) and is a key enzyme for DNA synthesis. High expression of TS is thought to be associated with poor prognosis in some kinds of cancers. However, this association has not been clarified for nonsmall cell lung carcinoma.

Hepatocellular carcinoma with an unusual neuroendocrine component.

We report a rare case of hepatocellular carcinoma (HCC) with an unusual neuroendocrine component. During a follow-up study for chronic hepatitis C in a 71-year-old man, a nodular lesion showed rapid growth from 1 cm to 4 cm in diameter within 3 months. Histologically, the tumor was consistent with moderately differentiated HCC, but was intermingled with nests of small round cells with scarce cytoplasm, which resembled those found in small cell carcinoma.
