PURPOSE To evaluate the prognostic value of vascular endothelial growth factor (VEGF)-D and VEGF receptor (VEGFR)-3 in endometrial carcinoma. EXPERIMENTAL DESIGN We assessed the levels of immunoreactivity for VEGF-D and VEGFR-3 in 71 endometrial carcinomas, 14 complex atypical endometrial hyperplasias, and 16 normal endometria by immunohistochemistry.

Human hepatocellular carcinomas (HCC) are known to frequently exhibit clear-cell or fatty change. The expression of three enzymes related to fatty acid metabolism, the peroxisomal bifunctional enzyme (enoyl-CoA hydratase/3-hydroxyacyl-CoA dehydrogenase, BE), cytosolic carbonyl reductase (CR) and the α-class glutathione S-transferase (GST) was investigated(More)
OBJECTIVE The purpose of this study was to determine whether para-aortic lymphadenectomy improves disease-related survival (DRS) in stage IIIc endometrial cancer. METHODS A total of 63 patients with stage IIIc endometrial carcinoma underwent primary radical surgery in the Tohoku Gynecologic Cancer Unit from 1993 to 2004. All patients had modified radical(More)
The purpose of this study was to evaluate the effectiveness and safety of concurrent chemoradiotherapy using weekly nedaplatin for the treatment of locally advanced squamous cell carcinoma of the uterine cervix. Nedaplatin at 30 mg/m(2) was administered weekly 6 times with a concurrent external beam and intracavity radiotherapy. External beam radiation was(More)
The choroid in the eye provides vascular support for the retinal pigment epithelium (RPE) and the photoreceptors. Vascular endothelial growth factor (VEGF) derived from the RPE has been implicated in the physiological regulation of the choroidal vasculature, and overexpression of VEGF in this epithelium has been considered an important factor in the(More)
Recent reports have shown that peroxisome proliferator-activated receptor (PPAR)alpha ligands reduce growth of some types of malignant tumors and prevent carcinogenesis. In this study, we investigated the inhibitory effect of clofibric acid (CA), a ligand for PPARalpha on growth of ovarian malignancy, in in vivo and in vitro experiments using OVCAR-3 and(More)
BACKGROUND It was recently reported that high expression of peroxisome proliferator-activated receptor gamma (PPARgamma) and low expression of cyclooxygenase-2 (COX-2) might be involved in the inhibition of ovarian tumor progression and confirmed that PPARgamma activation could suppress COX-2 expression via the nuclear factor-kappaB pathway in ovarian(More)
The aim of this study was to investigate the prognostic role of the pretreatment neutrophil-to-lymphocyte ratio (NLR) as a predictive marker prior to treatment ofcervical cancer with radiation therapy (RT) alone or concurrent chemoradiation therapy (CCRT). Fifty-six patients with squamous cell carcinoma (SCC) of the uterine cervix who underwent RT or CCRT(More)
BACKGROUND The endometrial stromal sarcoma (ESS) is a rare neoplasm of the uterine origin. Intracardiac metastasis from the low-grade ESS is an extremely rare event. A case of a patient who successfully underwent surgical extraction of metastatic tumors of the low-grade ESS in the right ventricle is described in the present report. CASE A 48-year-old(More)
