Background/aim: Immune-checkpoint inhibitors have recently shown great promise in treating various cancers, but often cause immune-related adverse events (irAEs). Simultaneous drug-induced hypothyroidism and isolated adrenocorticotropic hormone (ACTH) deficiency are rare irAEs. This combination of irAEs is associated with paradoxical endocrine dysfunction characterized by large amounts of thyroid-stimulating hormone (TSH) and small amounts of ACTH in the anterior lobe of the pituitary.

Many reports have described the clinical effects of immune checkpoint inhibitors (ICIs), supporting their utility as a promising therapy that will achieve prominent effects even in patients resistant to cytotoxic anticancer drugs or gene-targeting therapy. ICIs may also prolong overall survival.

We have experienced an extremely rare anomaly of the right superior PV.
Presentation Of Case: A 74-year-old man patient with right lung cancer visited our hospital.
Solitary fibrous tumors (SFTs) are relatively rare neoplasms that commonly occur in the pleura. The pathological feature of SFTs is a proliferation of spindle-shaped cells in interlacing or storiform fascicles. SFTs appear to derived from pluripotential submesothelial cells, but not the covering mesothelium.

The designation is used for lesions that show increased cellularity with a fascicular growth pattern and frequent extension. Our search of literature only revealed one case of a primary CFH of the lung.

In contrast, pulmonary fibroleiomyomatous hamartoma, which consists of interlacing bundles of smooth muscle cells admixed with fibrous tissue and numerous tubular or cleft-like epithelial inclusions, is a rare type of hamartoma.

A 90-year-old woman who was admitted to our hospital because of a urinary tract infection was treated with a course of antibiotics, but she demonstrated a rapidly progressive course with dyspnea.

Trauma, neoplasms, infection, and degenerative disease are the most common causes of this condition, whereas idiopathic eventration of the diaphragm is relatively infrequent.
Presentation Of Case: We herein present the rare case of an 85-year-old female with idiopathic eventration of the bilateral diaphragm.
Introduction: We herein describe a rare case of a pulmonary arteriovenous fistula (PAVF).
Presentation Of Case: The patient was a 20-year-old asymptomatic female, admitted to our hospital because of an abnormal shadow in the right lung field on chest X-rays. Chest computed tomography (CT) revealed two nodules with well-defined margins in the right upper and lower lobes.
Introduction: While hypervascular lesions in the lung are known to mimic pulmonary arteriovenous malformation (PAVM), here we report a rare case of lung granuloma mimicking PAVM, on which video-assisted thoracic surgery (VATS) was performed.
Presentation Of Case: A 76-year-old woman without any symptom was admitted to our hospital because of abnormal shadow in the left lung field on chest X-ray. A 20mm×14mm nodule with well-defined margins and smooth contours in the left upper segment was detected in her chest computed tomography (CT).
Azygos vein aneurysms are very rare causes of mediastinal masses and are usually accidental findings on chest roentgenography. Most are detected in patients with portal hypertension or venous malformations. An idiopathic azygos vein aneurysm is assumed to be congenital and is much more exceptional.

Because of its rarity, its biological and clinical characteristics are still not fully understood and, to date, no standard therapy has been developed. Here, we present a case and a review of the literature regarding this cancer, focusing on clinicopathological findings and treatment.

Therefore, gene expression profile in the PUF/spheroid culture is hypothesized to be different from that in the monolayer culture. The aim of this study is to clarify the characteristic gene expression in PUF/spheroid-cultured Hep G2 cells, as a cell source for bioartificial liver (BAL), using microarray analysis.

Therefore, the specific inhibition of TNF-alpha could improve the viability of the hepatic graft upon reperfusion.
Methods: We assessed the efficacy of TNF-alpha antisense (TNF-AS) oligodeoxynucleotides (ODNs) delivery to KC in a rodent liver transplantation model.
Aim: To elucidate the immunologic parameters for the outcome of patients with malignant tumors, especially esophageal squamous cell carcinoma (ESCC) associated with high malignant potential.
Methods: Clinicopathologic features were compared between patients with lower and higher CD4 and CD8 values as well as CD4/CD8 ratio in peripheral blood.
Results: The survival rate of patients with higher CD4 value was significantly better than that in patients with lower CD4 value (P = 0.
Cytomegalovirus infections are associated with a high mortality rate after liver transplantation, but they are treated successfully by administration of the combination of ganciclovir plus intravenous immunoglobulin. We herein describe cytomegalovirus esophagitis in a patient having gastrointestinal symptoms such as dysphagia, retrosternal pain and epigastralgia after liver transplantation was detected by performing the surveillance of endoscopy. At first, the findings of endoscopy that were segmental erosive areas but no ulcerative areas on the esophageal lumen were unusual in this case of cytomegalovirus infections, but cytomegalovirus esophagitis was confirmed by cytomegalovirus immunohistochemical stain using biopsies.

Patients And Methods: Six randomized controlled trials on node-negative breast cancer patients were conducted from 1992 through 1995 in Japan that included the three, three-arm trials (control [no adjuvant], UFT, and tamoxifen [TAM] groups) and the three, four-arm trials (control, UFT, TAM, and UFT plus TAM groups). Pooled analysis was performed on the data obtained from these six trials (involving 2,934 patients).
In this paper we report a case of hyperplastic polyp with malignant transformation. The patient was followed up by annual radiographic and endoscopic examination during 9 years. The first gastroscopy revealed a semi-pedunculated polyp beneath the esophageal-cardiac junction, 1.

Methodology: Sixty-six patients undergoing colorectal resection were studied. Patients in the Study group began on 7.
Background/aims: It has been reported that non-insulin dependent diabetes mellitus (NIDDM) is one of the risk factors for colorectal cancer. Usually, in the pre-NIDDM state, hyperinsulinemia is seen for 5 to 8 years. Insulin is the growth factor of epithelial and cancer cells of colon and rectum.

AAH may have a role in regulating invasive or metastatic tumor cell growth of human intrahepatic cholangiocarcinoma.
Background: Recent studies demonstrated increased expression of the AAH gene in the majority of cholangiocarcinomas.
Reported frequencies for microsatellite instability (MSI) in oesophageal cancer differ widely in the literature, perhaps due to the high incidence of loss of heterozygosity (LOH) in this cancer. Using high-resolution fluorescent microsatellite analysis (HRFMA), we analysed microsatellite alterations in detail in 50 Japanese and 50 Chinese patients with squamous cell carcinoma in the oesophagus. In HRFMA, several devices have been developed to improve the detection characteristics, reproducibility of polymerase chain reaction and the migration accuracy of electrophoresis.
