OBJECTIVE Vascular endothelial growth factor (VEGF) plays an important role in cervical carcinogenesis. We hypothesized that VEGF genetic polymorphisms may affect cancer susceptibility, angiogenesis, and survival in patients with early cervical cancer. METHODS Among 215 healthy subjects and 199 early cervical cancer patients who were treated with surgical(More)
PURPOSE To describe the computed tomographic (CT) findings of ectopic pancreas and to identify the features that differentiate it from other similarly manifesting gastric submucosal tumors such as gastrointestinal stromal tumor (GIST) and leiomyoma, which are the most common gastrointestinal submucosal tumors. MATERIALS AND METHODS This retrospective(More)
PURPOSE The aim of this study is to retrospectively analyze the variety of CT findings based on new pathologic classification. MATERIALS AND METHODS During a 10-year period, 59 histopathologically proven pancreatic SCTs and 13 SCTs confirmed with typical image findings and strict clinical criteria were enlisted. Two radiologists analyzed CT images for the(More)
Cetuximab is a monoclonal antibody targeting epidermal growth factor receptor (EGFR). The present study investigated the association between germline genetic polymorphisms and the treatment outcome of cetuximab plus modified leucovovin, fluorouracil, and oxaliplatin (FOLFOX)6 chemotherapy in advanced gastric cancer (AGC). DNA from peripheral blood(More)
HER-2 gene amplification and the overexpression of HER-2 protein have been observed in various solid tumors, including gastric carcinomas. HER-2 gene amplification has attracted research attention since the development of the new therapeutic agent trastuzumab. Here, we evaluated HER-2 status in the surgically resected tissues of 248 gastric carcinoma cases(More)
OBJECTIVE Caveolin 1 gene is known as a tumor promoter or suppressor, depending on the tumor type and/or tumor stage. We aimed to investigate the clinical significance of caveolin 1 protein (Cav1) expression in gastric cancer (GC). METHODS Immunohistochemistry was performed on tissue array slides containing 405 GC specimens. The relationships between Cav1(More)
Ataxia-telangiectasia mutated (ATM) is a Ser/Thr protein kinase that plays a critical role in DNA damage-induced signaling and initiation of cell cycle checkpoint signaling in response to DNA-damaging agents such as ionizing radiation. We have previously reported the ATM protein loss by immunohistochemistry (IHC) in 16% of human gastric cancer (GC) tissue.(More)
BACKGROUND To investigate the utility of CT volumetry for primary gastric lesions in the prediction of pathologic response to neoadjuvant chemotherapy in patients with resectable advanced gastric cancer (AGC). MATERIALS AND METHODS Thirty-three consecutive patients with resectable AGC stage >or=T2 and N1), who had been treated with neoadjuvant(More)
Metastasis is a multi-step process involving many biomolecular changes and DNA methylation is one such molecular change. Although differences in DNA methylation have been reported in matched primary and metastatic mammary carcinoma, no such differences have been reported in gastric carcinoma. Accordingly, to investigate whether DNA methylation profiles in(More)
BACKGROUND Success factors of laparoscopic nerve-sparing radical hysterectomy (LNRH) to preserve bladder function are little known despite its widespread use. Thus, we conducted a protocol-based prospective cohort study to evaluate clinicopathologic factors for preserving autonomic nerves and its impact on duration of postoperative catheterization (DPC).
