BACKGROUND BRAF mutation is an important diagnostic and prognostic marker in patients with papillary thyroid carcinoma (PTC). To be applicable in clinical laboratories with limited equipment, diverse testing methods are required to detect BRAF mutation. METHODS A shifted termination assay (STA) fragment analysis was used to detect common V600 BRAF(More)
SIRT1 (silent mating-type information regulation 2 homologue 1)-mediated cellular resistance to various stresses is negatively regulated by deleted in breast cancer 1 (DBC1), which was originally reported to be deleted in breast cancer. However, the suggested functions of SIRT1 as a potential tumor promoter and of DBC1 as a potential tumor suppressor have(More)
Only few studies have evaluated the usefulness of the GLUT1 and p53 status of pancreatobiliary tract carcinomas in revealing tumorigenesis. We studied GLUT1 and p53 immunoexpression in a total of 355 cases of the pancreatobiliary carcinoma to determine the biological significance of GLUT1 and p53 expression. Positive expression of GLUT1 was identified in 38(More)
Bone involvement is an unusual manifestation of secondary syphilis, but little information is available in the English-language literature. We carried out a systematic review of the English-language literature from 1964 to 2013, describing cases of secondary syphilis with bone involvement. We also describe a case of secondary syphilis with multiple(More)
OBJECTIVES:Despite an increase in the reports of intraductal papillary neoplasm of the bile duct (IPN-B), the clinical characteristics and long-term prognosis of this disease are not well known compared with those of intraductal papillary mucinous neoplasms of the pancreas. The objective of our study was to compare the clinical features, radiologic(More)
OBJECTIVES To assess the characteristics of pseudocapsule (PC) in localized renal cell carcinoma (RCC) by analyzing the rates of completeness of PC and pseudocapsular invasion and clinical and pathological risk factors of it. MATERIALS AND METHODS Between February 2013 and September 2015, data were gathered prospectively from 180 consecutive patients who(More)
The role of adjuvant chemotherapy and the value of molecular biomarkers in bladder cancer have not been determined. We aimed to assess the predictive and prognostic values of excision repair cross-complementation 1 (ERCC1) in identifying appropriate patients who may potentially benefit from adjuvant chemotherapy for bladder cancer. A retrospective analysis(More)
Peritoneal loose bodies (PLBs) are usually discovered incidentally during laparotomy or autopsy. A few cases of giant PLBs presenting with various symptoms have been reported in the literature. Here, we describe a case of a giant PLB incidentally found in the pelvic cavity of a 50-year-old man. Computed tomography revealed a free ovoid mass in the pelvic(More)
PURPOSE Tumor-associated macrophages (TAMs) play a significant role in tumor progression and angiogenesis. However, the prognostic value of TAMs in different histologic locations of gastric cancer (GC) is still unknown. We evaluated the distribution of TAMs in different histologic locations to investigate its importance in predicting prognosis and the(More)
