Spontaneous intercostal artery bleeding occurring simultaneously in numerous vessels during antithrombotic therapy with mechanical circulatory support: a case report.

Background: Intercostal artery bleeding often occurs in a single vessel; in rare cases, it can occur in numerous vessels, making it more difficult to manage.

Case Presentation: A 63-year-old Japanese man was admitted to the emergency department owing to sudden chest and back pain, dizziness, and nausea. Emergency coronary angiography revealed myocardial infarction secondary to right coronary artery occlusion.

Prognostic value of combined psoas muscle mass and controlling nutritional status in patients with pancreatic ductal adenocarcinoma: a retrospective cohort study.

Background: Pancreatic ductal carcinoma (PDAC) is an extremely poor prognostic disease. Even though multidisciplinary treatment for PDAC has developed, supportive therapies, such as nutritional therapy or perioperative rehabilitation to sustain and complete aggressive treatment, have not yet been well-established in PDAC. The aim of this study was to elucidate the relationship between the combined index using psoas muscle mass index (PMI) values and controlling nutritional status (CONUT) score and prognosis.

Metastatic lung tumor from hepatocellular carcinoma with tumor thrombus invasion in the pulmonary vein: a case report.

Background: Metastatic lung tumor with a tumor thrombus in the peripheral pulmonary vein is very rare. We present a case of a metastatic lung tumor from hepatocellular carcinoma (HCC) with tumor thrombus invasion in the pulmonary vein that was diagnosed preoperatively and underwent complete resection by segmentectomy.

Case Presentation: A 77-year-old man underwent laparoscopic lateral segment hepatectomy for HCC eight years ago.

[Hyperammonemic encephalopathy after treatment with modified FOLFOX6 regimen for recurrent gastric cancer:a case report].

A 64-year-old female received modified FOLFOX6 therapy with continuous administration of a high concentration of 5-fluorouracil (5-FU) for recurrence of peritoneal dissemination after total gastrectomy. Twenty-nine hours after the administration, there was the sudden onset of altered consciousness and hepatic dysfunction accompanied by hyperammonemia. The consciousness and hepatic function improved the following day after treatment with branched-chain amino acid formulation, lactulose, fresh frozen plasma, and continuous hemodiafiltration.

Colonic varices treated with embolization after pancreatoduodenectomy with portal vein resection: a case report.

Background: Pancreatoduodenectomy with resection of the portal vein or superior mesenteric vein confluence has been safely performed in patients with pancreatic head cancer associated with infiltration of the portal vein or superior mesenteric vein. In recent years, left-sided portal hypertension, a late postoperative complication, has received focus owing to increased long-term survival with advances in chemotherapy. Left-sided hypertension may sometimes cause fatal gastrointestinal bleeding because of the rupture of gastrointestinal varices.

A rare case of localized IgG4-related sclerosing cholecystitis mimicking gallbladder cancer.

IgG4-related sclerosing cholecystitis is generally associated with IgG4-related sclerosing cholangitis and presents with diffuse, circumferential thickening of the gallbladder wall. We report a rare case of localized IgG4-related sclerosing cholecystitis without IgG4-related sclerosing cholangitis, which was difficult to differentiate from gallbladder cancer preoperatively. A 56-year-old man with suspected IgG4-related disease or gallbladder cancer was admitted to our ward.

Prognostic value of MAGEA4 in primary lung cancer depends on subcellular localization and p53 status.

Melanoma antigen family A4 (MAGEA4), a cancer/testis antigen, is overexpressed and is thus an immunotherapy target in various malignant tumors, including non-small cell lung cancer. However, whether MAGEA4 induces or inhibits the apoptosis of lung cancer cells remains controversial, as is its prognostic significance, particularly since there is no reliable method with which to detect MAGEA4 specifically. In this study, we optimized assay conditions to detect MAGEA4 based on cells transiently transfected with MAGEA genes, and found that MAGEA4 was expressed in four of eight non-small cell lung cancer cell lines, and in 25.

Minimally invasive surgery for esophageal cancer after esophageal perforation.

Both esophageal rupture and esophageal cancer are life-threatening diseases. We report a case of esophageal cancer that occurred after esophageal rupture was treated with thoracoscopic and laparoscopic surgery. A 76-year-old man presented with vomiting followed by epigastric pain and was diagnosed with spontaneous esophageal rupture.

Time-dependent transition of the immunoglobulin G subclass and immunoglobulin E response in cancer patients vaccinated with cholesteryl pullulan-melanoma antigen gene-A4 nanogel.

A phase I+II clinical trial of vaccination with MAGE-A4 protein complexed with cholesteryl pullulan melanoma antigen gene-A4 nanogel (CHP-MAGE-A4) is currently underway in patients with MAGE-A4-expressing cancer. In the present study, the primary phase I endpoint was to test the safety of the administration of 300 µg CHP-MAGE-A4 with and without OK-432. Another aim of the study was to clarify the details of the specific humoral immune response to vaccination.

Down-regulation of Human Leukocyte Antigen class I heavy chain in tumors is associated with a poor prognosis in advanced esophageal cancer patients.

The HLA class I antigen processing machinery (APM) plays a crucial role in the anticancer immune response. The aim of this study was to assess the clinical significance of APM components in esophageal cancer. A total of 11 esophageal cancer cell lines were evaluated by Western blot analysis for 13 HLA class I APM components.

Sequence confirmation and characterization of the mouse Ssxa gene: Ssxa protein is cleaved and the N-terminal cleaved fragment translocates into the nucleus.

This is the first demonstration of a stop codon in the sequence of mouse Ssxa and characterization of the biological behavior of Ssxa protein. Cancer testis antigen (CTA) is known as a target of immunotherapy against cancer, and Ssxa is one of the CTAs. Although a CTA would be useful to establish a mouse cancer vaccine model using endogenous antigen, the stop codon was not identified in the sequence of Ssxa cDNA that was previously reported.

A case of primary pulmonary hypertension with pulmonary tumor.

A 64-year-old female with a 9-year history of primary pulmonary hypertension developed a solid pulmonary tumor. Partial lung resection was planned for diagnosis. Although prostacyclin was increased to 8 ng/kg/min, she did not tolerate the decubitus position and one-lung ventilation, and her pulmonary arterial pressure rose to 110/45 mmHg.

Simultaneous resection of bilateral intralobar and extralobar pulmonary sequestrations with video-assisted thoracoscopic surgery.

The term pulmonary sequestration is applied to a pulmonary lobe or portion of a lobe that is supplied by an anomalous systemic artery and drain either into the systemic or pulmonary veins. The conditions are divided into intralobar pulmonary sequestration, in which the sequestration is situated inside the visceral pleura of a normal lobe, and extralobar sequestration, in which the sequestration is surrounded by its own pleura. Most sequestrations are unilateral; bilateral sequestrations are rare.

Incarcerated femoral hernia with ovary and fallopian tube torsion in an infant: a rare occurrence.

Incarcerated femoral hernia with ovary and fallopian tube torsion is very rare in children. We herein report a case of incarcerated femoral hernia with ovary and fallopian tube torsion in a 7-month-old female who was diagnosed on the basis of operative findings. We released the torsion of the left fallopian tube.
