The autopsy findings of patients who died of recurrence after curative resection of pancreatic cancer may afford a reliable guide to increase long-term survival after surgery. Recurrence patterns were analyzed for 27 autopsied patients who had undergone potentially curative resection of pancreatic cancer. The pattern of recurrence was classified as follows:(More)
We conducted clinicopathologic and immunohistochemical analyses of the prevalence of Epstein-Barr virus (EBV) among 24 patients with malignant lymphoma complicating systemic rheumatic diseases. (SRD) These 24 patients included 17 with rheumatoid arthritis (RA), 3 with systemic lupus erythematosus (SLE), 2 with systemic sclerosis (SS), and 2 with(More)
The fibroblast growth factor receptor (FGFR)-3 gene encodes a receptor tyrosine kinase that is frequently mutated in non-muscle invasive bladder cancer (NMIBC). A sensitive and quantitative assay using peptide nucleic acid-mediated real-time PCR was developed for detecting FGFR3 mutations in the urine samples and evaluated as a molecular marker for(More)
Somatic mutations of the fibroblast growth factor receptor 3 (FGFR3) gene were detected by peptide nucleic acid (PNA)-mediated real-time PCR clamping. Mutation was detected in negative control containing only wild-type DNA due to a misincorporation of dNTPs to PNA binding sites when the amount of template DNA was decreased to 1 ng. Thus, the amount of(More)
Desmoid tumor, also referred to as aggressive fibromatosis, is a relatively rare, locally infiltrative, histologically benign tumor. This report details a case of desmoid tumor presented as a superior sulcus tumor, which showed a unique manifestation in the vertebral bodies on computed tomography.
We report a case of colitic cancer detected by target biopsies at surveillance colonoscopy in a patient with long-standing and extensive ulcerative colitis. At first, the detected colitic cancer was removed by endoscopic mucosal resection as the patient refused surgical resection. However, total proctocolectomy with an ileal-J-pouch anal anastomosis was(More)
OBJECTIVE We generated cytomegalovirus (CMV)-specific cytotoxic T lymphocytes (CTL) in vitro using dendritic cells (DC) pulsed with crude CMV antigens (Ag). PATIENTS AND METHODS Mononuclear cells from healthy CMV-seropositive or seronegative volunteers and from stem cell transplant (SCT) recipients were cultured with CD14(+) monocyte-derived DC prepulsed(More)
The regional levels of several cell marker proteins in the brain and the ability of operant discrimination learning on a multiple fixed ratio (FR), fixed interval (FI) schedule were determined in rats with microencephaly induced by prenatal treatment with methylazoxymethanol (MAM), an antimitotic agent, on the 11 th to 13 th days (Group A) or on the 15 th(More)
We report a case of synchronous hepatocellular carcinoma (HCC) and malignant peritoneal mesothelioma (MM-per). A 56-year-old man with no past history of asbestos exposure, chronic viral hepatitis, or alcoholic liver injury was admitted to our hospital with left flank pain and abdominal tumor. Partial hepatectomy, splenectomy, partial diaphragm resection,(More)
Dear Dr. Bedrossian: In the literature, the cytological findings of pleural effusion in marginal zone B-cell lymphoma (MZBCL) are limited. Here, we report a case of nodal MZBCL showing prominent plasma cell differentiation in the pleural effusion. The patient was an 81-year-old Japanese woman who had a one-year history of a left submandibular mass. She had(More)
