PURPOSE Histologic components of the TNM classification system have been repeatedly revised since the fifth edition (TNM5). TNM classification revisions provide different criteria for categorizing tumor nodules without residual lymph node structure (ND). However, there are few systematic evaluations regarding the effectiveness of these revisions. PATIENTS(More)
A burned-out testicular tumor with lung and lymph node metastases presented high serum levels of DU-PAN-2. However, the serum levels of CA19-9, alpha-fetoprotein, beta-human chorionic gonadotropin, and sialyl Lewis X were normal. A biopsy of the cervical lymph nodes revealed embryonal carcinoma. Four courses of chemotherapy, including cisplatin, etoposide,(More)
GASDERMIN B (GSDMB) belongs to the novel gene family GASDERMIN (GSDM). All GSDM family members are located in amplicons, genomic regions often amplified during cancer development. Given that GSDMB is highly expressed in cancerous cells and the locus resides in an amplicon, GSDMB may be involved in cancer development and/or progression. However, only limited(More)
Aldo-keto reductase family 1, member B10 (AKR1B10), a cancer-related oxidoreductase, is expressed in well-differentiated hepatocellular carcinomas (HCCs). However, AKR1B10 levels are minimal in normal liver tissues (NLs), similar to the 70-kilodalton heat shock protein (HSP70) and glypican-3. Moreover, the role of AKR1B10 in chronic hepatitis or cirrhosis,(More)
OBJECTIVE This study aimed to determine the optimal categorization of extramural tumor deposits lacking residual lymph node (LN) structure (EX) in colorectal cancer staging. BACKGROUND The TNM classification system categorizes EX on the basis of their contour characteristics (the contour rule). METHODS We conducted a multicenter, retrospective,(More)
Sweet's disease with central nervous system involvement, tentatively named neuro-Sweet's disease, has rarely been reported. Although systemic corticosteroid therapy is highly effective for neurologic symptoms in neuro-Sweet's disease, relapse is common. Here, we describe the case of a 38-year-old Japanese man who presented with relapsing neuro-Sweet's(More)
We previously reported a relationship between depth of submucosal invasion of early colorectal carcinomas and desmoplastic reaction (DR). However, poor inter-observer agreement on the histopathological diagnosis of DR in biopsy specimens with hematoxylin and eosin (H&E) staining has been the major critique of this tool. In this study, reproducibility of the(More)
We report a 74-year-old man with triple synchronous cancers occurring in the gallbladder, common bile duct, and pancreas. The patient had consulted a nearby physician because of epigastralgia and icterus. On September 30, 1997, the patient was admitted to our department for further evaluation and treatment. Abdominal computed tomography (CT) showed(More)
