BACKGROUND AND PURPOSE Plaque morphologic features have been suggested as a complement to luminal narrowing measurements for assessing the risk of stroke associated with carotid atherosclerotic disease, giving rise to the concept of "vulnerable plaque." The purpose of this study was to evaluate the ability of multidetector-row CT angiography (CTA) to assess the composition and characteristics o...
Epidemiologic studies have reported the underrepresentation of cervical precancerous lesions caused by human papillomavirus (HPV) types 18 and 45 (HPV18/45) compared with the proportion of cervical cancers attributed to these HPV types. We investigated the timing of diagnosis of histologic cervical intraepithelial neoplasia grade 3 or worse (CIN3+) using data from the atypical squamous cells of...
BACKGROUND Neuroblastoma (NB), is a neuroectodermal tumor derived from neural crest cells, and it is the second most common pediatric malignant tumor. The biological and clinical behavior of NB is very heterogeneous. This study was conducted to evaluate the expression of Ki-67, p53 and VEGF markers in tissues obtained from NB patients with different histologic types and stage. MATERIALS AND M...
PURPOSE To investigate the prognostic factors and effectiveness of postoperative radiotherapy alone for endometrial carcinoma. MATERIALS AND METHODS Sixty four patients with stage I-III endometrial cancer (EC) treated with postoperative radiotherapy alone between January 1989 and December 2008 at the Keimyung University Dongsan Medical Center were chosen for the present study. Typically, tota...
PURPOSE To prospectively evaluate the ability of diffusion-weighted (DW) magnetic resonance (MR) imaging to be used to determine the T stage of bladder cancer and to measure the correlation between the apparent diffusion coefficient (ADC) and histologic grade. MATERIALS AND METHODS This study was approved by the local institutional review board. All patients gave written informed consent. For...
Esophageal cancer incidence rates have been increasing over the past years and survival remain low. According to Global Cancer Observatory, 3.1% of new cases consists esophageal 5.5% deaths was due cancer. Histologic classification comprises either squamous cell carcinoma (SCC) or Adenocarcinoma. Other types are reported be uncommon. We present a case 33-year old male admitted progressive dysph...
BACKGROUND Recent studies suggest that the use of combined estrogen and progestin hormone replacement therapy is associated with an increased risk of invasive lobular carcinoma (ILC), but that it has little association with risk of invasive ductal carcinoma (IDC). Also, the incidence rates of ILC have risen over the past 10 years while those of IDC have remained constant. Differences in surviva...
OBJECTIVES Positron emission tomography using [(18)F]-fluoro-2-deoxy-D-glucose ((18)F-FDG-PET) plays an important role in many oncological settings. In this study, we assessed the utility of (18)F-FDG PET-CT for predicting the histologic type and stage of thymic epithelial tumours. METHODS We retrospectively analyzed 58 patients with thymic epithelial tumours who underwent PET-CT before treat...
BACKGROUND Ovarian carcinoma is composed of five major histologic types, which associate with outcome and predict therapeutic response. Our aim was to evaluate histologic type assessments across the centers participating in the Ovarian Tumor Tissue Analysis (OTTA) consortium using an immunohistochemical (IHC) prediction model. METHODS Tissue microarrays (TMA) and clinical data were available ...
