Ovarian cancer is the most lethal gynecological malignancy in the western world. Although patients with early-stage ovarian cancer generally have a good prognosis, approximately 20%-30% of patients will die of the disease, and 5-year recurrence rates are 25%-45%, highlighting the need for improved detection and treatment. We investigated the role of VAV1, a(More)
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. The authors evaluated 16 patients diagnosed with ESS at the Hyogo(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)
OBJECTIVE To analyze the factors prognostic of survival in patients with advanced epithelial ovarian cancer (EOC) treated with neoadjuvant chemotherapy (NAC) followed by interval debulking surgery. METHODS Outcomes were retrospectively in patients with advanced EOC or peritoneal cancer who received neoadjuvant paclitaxel and carboplatin chemotherapy every(More)
OBJECTIVE Cervical cancer is the second most common cancer in females worldwide, and the majority of squamous cell carcinomas and adenocarcinomas are associated with high-risk human papillomavirus (HPV) infection. However, the relationship between clear cell carcinoma of the cervix (CCCC) and HPV is unclear. In this study, we sought to determine if HPV(More)
A high positivity of cold activation of complement has been reported in Japanese patients having hepatitis B virus-negative chronic hepatitis. Although the cause of cold activation of complement is unknown, the involvement of hepatitis C virus (HCV) has been suspected. We studied the positivity of cold activation of complement in 253 patients, including 93(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)
A 52-year-old woman presented to our hospital due to elevated liver enzyme levels and hypereosinophilia. Liver biopsy specimens revealed chronic hepatitis with abundant eosinophils and immunoglobulin G4(IgG4)-positive plasma cell infiltration. Systemic lymphadenopathy, including that involving the hepatic hilar lymph nodes, was observed on computed(More)
A 53-year-old female who complained of constipation and abdominal fullness was referred to our hospital. A tender low abdominal mass was palpable. Imaging (abdominal ultrasonography, CT, and MRI) revealed that the tumor had spread to the mesosigmoid and the superior mesentery. The tumor was very difficult to diagnose on the basis of imaging alone.(More)
BACKGROUND AND AIM Multi-detector-row computed tomography (MDCT) has been reported to be a potentially useful modality for detection of the bleeding origin in patients with acute upper massive gastrointestinal (GI) bleeding. The purpose of this study is to investigate the efficacy of MDCT as a routine method for detecting the origin of acute upper GI(More)
