BACKGROUND We investigated the relationship of the immunohistochemical expression status of manganese superoxide dismutase (MnSOD), catalase, glutathione peroxidase (GPx), and myeloperoxidase (MPO) in buccal mucosal squamous cell carcinoma (SCC) with clinicopathologic parameters and prognosis. METHODS The expression status of MnSOD, GPx, catalase, and MPO(More)
Female urethral diverticulum is an uncommon pathologic entity and can manifest with a variety of symptoms involving the lower urinary tract. Selection of the appropriate imaging modality is critical in establishing the diagnosis. Urethrography has traditionally been used in the evaluation of urethral diverticulum but provides only intraluminal information.(More)
Vascular leiomyosarcoma is extremely rare and represents < 2% of all leiomyosarcomas. The frequency of occurrence of leiomyosarcomas in veins is five times more than in arteries, with approximately half of them occurring in the inferior vena cava. Although leiomyosarcomas originating from large arteries or veins have been widely reported, similar tumors of(More)
OBJECTIVES Cyclins and cyclin-dependent kinase (CDK) complexes have important regulatory roles during cell cycle progression and can be used as prognostic markers in various kinds of malignant tumors. This study investigated the expression of proliferative cell nuclear antigen (PCNA), p53, Rb, p27(kip1), and cyclin D1 by immunostains in bladder tumors,(More)
OBJECTIVE The present study investigated the relationship between the expression of manganese superoxide dismutase (MnSOD), catalase, glutathione peroxidase (GPx), and myeloperoxidase (MPO) in buccal mucosal squamous cell carcinoma (SCC), and the risk of second primary tumors (SPTs). STUDY DESIGN Immunohistochemistry was performed to examine the(More)
BACKGROUND OCT4, SOX2, and NANOG are major transcription factors related to stem cell self-renewal and differentiation. The aim of this study was to examine the association of OCT4, SOX2, and NANOG expression levels with the development and prognosis of patients with oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS Expression levels of OCT4,(More)
DNA methylation at the 5 position of cytosine (5mC) is an epigenetic hallmark in cancer. The 5mC can be converted to 5-hydroxymethylcytosine (5hmC) through a ten-eleven-translocation (TET). We investigated the impact of 5mC, 5hmC, TET1, and TET2 on tumorigenesis and prognosis of breast cancer. Immunohistochemistry was used to assess the levels of 5mC, 5hmC,(More)
Primary non-Hodgkin's lymphoma of bone (PLB) is a rare disorder representing less than 1% of all non-Hodgkin's lymphomas and has rarely been reported in Taiwan. A retrospective clinicopathological study was performed according to the 2002 World Health Organization criteria and identified 14 cases during a 13-year period in 2 medical centers in southern(More)
BACKGROUNDS Oral cancer is the 4th leading cause of cancer death for males and the top cancer in young adult males in Taiwan. Tongue squamous cell carcinoma (TSCC) is a common oral cancer and generally associated with poor prognosis. Global DNA hypomethylation at the 5 position of cytosine (5mC) is a well-known epigenetic feature of cancer. Therefore, the(More)
Upper gastrointestinal bleeding from primary aortoduodenal fistula (PADF) is unusual and fatal. The etiology of PADF from tuberculous aortitis is rare. We report a 69-year-old male patient who suffered recurrent hematemesis and hematochezia with hypovolemic shock of unknown origin. Initial endoscopy failed to lead to a diagnosis. A bleeder over the third(More)
