Endocervical-type mucinous adenocarcinoma (ECA) of the uterine cervix is defined as a tumor composed of cells resembling those of the endocervical glands, but recent studies have demonstrated that a minority of ECAs displays a gastric immunophenotype. The aim of this study was to assess the significance of the gastric phenotype. Fifty-three cases of(More)
PURPOSE High-grade serous ovarian cancers are heterogeneous not only in terms of clinical outcome but also at the molecular level. Our aim was to establish a novel risk classification system based on a gene expression signature for predicting overall survival, leading to suggesting novel therapeutic strategies for high-risk patients. EXPERIMENTAL DESIGN(More)
From January 1990 to December 2004, the prognosis of 28 patients with stage Ib1 adenosquamous cell carcinoma (ASC) were assessed in comparison with those of matched counterparts of pure adenocarcinoma (ADC) and squamous cell carcinoma (SCC). The mean ages were 46.6, 48.3, and 48.5 years for patients with ASC, ADC, and SCC, respectively. All the patients(More)
OBJECTIVE The purpose of this study was to compare surgical outcomes using modified (type II) and traditional (type III) abdominal radical trachelectomy (ART) for fertility-sparing surgery in early cervical cancer. METHODS A prospectively maintained database of ART procedures was analyzed. Data were collected regarding age, stage, histology, operative(More)
Paclitaxel stabilizes microtubules, causing mitotic arrest and activating the spindle assembly checkpoint. We determined whether suppression of the checkpoint genes Mad2 and BubR1 affects paclitaxel resistance and whether overexpression of Mad2 protein in checkpoint-defective cells enhances paclitaxel sensitivity. Suppression of Mad2 and BubR1 in(More)
A subset of endocervical-type mucinous adenocarcinomas (ACs) of the uterine cervix exhibit a gastric phenotype and morphology, as reported in cases of minimal deviation AC in which the presence of human papillomavirus (HPV) has been rarely detected. To investigate the HPV-independent pathway of carcinogenesis in cases of gastric-type AC, we investigated the(More)
INTRODUCTION Paclitaxel is used widely in the treatment of breast cancer. Not all tumors respond to this drug, however, and the characteristics that distinguish resistant tumors from sensitive tumors are not well defined. Activation of the spindle assembly checkpoint is required for paclitaxel-induced cell death. We hypothesized that cyclin-dependent kinase(More)
OBJECTIVE Cancer cells have characteristics, such as high telomerase activity and high levels of migration activity and proliferation, which are very similar to those of germ cell lineages. In this study, we examined the expression of VASA, a germ cell lineage specific marker and evaluated its clinical significance in epithelial ovarian cancer (EOC). (More)
PURPOSE Endometrial stromal sarcomas (ESSs) are rare tumors and are divided into two groups: low-grade endometrial stromal sarcoma (ESS-LG) and undifferentiated endometrial sarcoma (UES). The purpose of this study was to compare the clinicopathological features and immunophenotypes of ESS-LG and UES. METHODS The authors evaluated 16 patients diagnosed(More)
Previously, we reported that ABCF2 protein expression is higher in clear cell than serous histotype of ovarian adenocarcinomas and that its expression correlates with chemoresponse in patients with clear cell ovarian cancer. In this study, we examined ABCF2 protein expression in mucinous, endometrioid, and poorly differentiated type of ovarian(More)
