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)
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)
Cyclin A-associated kinases, such as cyclin-dependent kinase 2 (CDK2), participate in regulating cellular progression from G(1) to S to G(2), and CDK2 has also been implicated in the transition to mitosis. The antitumor properties of CDK inhibitors, alone or in combination with taxanes, are currently being examined in clinical trials. Here, we examined(More)
Although the majority of smooth muscle neoplasms found in the uterus are benign, uterine leiomyosarcoma (LMS) is extremely malignant, with high rates of recurrence and metastasis. We earlier reported that mice with a homozygous deficiency for LMP2, an interferon (IFN)-γ-inducible factor, spontaneously develop uterine LMS. The IFN-γ pathway is important for(More)
A choriocarcinoma component with a malignant tumor is relatively rare. We present a case of an 85-year-old woman with mixed carcinoma, which was endometrioid adenocarcinoma with squamous differentiation, choriocarcinoma and a disseminated peritoneal nodule, which was papillary serous adenocarcinoma. The patient received surgery and conservative treatment.(More)
We herein present atypical histologic and immunohistochemical features of DSRCT. The various differential diagnoses of DSRCT may occasionally generate confusion. Cytogenetic analysis may solve diagnostic dilemmas such as that in our case. Further studies are required to establish a standard treatment for DSRCT.
AIM To evaluate the effect of abdominal radical trachelectomy on ovarian reserve and compare it with abdominal radical hysterectomy and a control group that did not have surgery. METHOD We enrolled eighteen women who had abdominal radical trachelectomy with pelvic lymphadenectomy and sixteen patients who had abdominal radical hysterectomy for this study.(More)
