Desmoplastic small round cell tumor (DSRCT) is a rare intra-abdominal tumor of uncertain histogenesis that occurs predominantly in young males. We report two cases of DSRCT in young women that presented clinically as ovarian tumor with extensive pelvic and abdominal dissemination. Both patients underwent debulking surgery and combined chemotherapy. After(More)
Combined chemotherapy with etoposide and cis-platinum (CDDP) is considered a second line regimen for refractory cases of ovarian cancer. In addition to the time-dependent cytocidal kinetic of etoposide, much attention has been paid to low-dose continuous administration of etoposide. In this study, ovarian cancer cells (SHIN-3) were continuously exposed to(More)
An extensive series of histological sections from various types of benign, borderline, and malignant human ovarian tumors were examined for expression of the p53 protein by immunohistochemical staining, using a new anti-p53 mouse monoclonal antibody. Positive staining for p53 was detected in 34% of all malignant ovarian cancer tissues. A high rate of(More)
The frequency of ovarian cancers in Japan has increased; however, doubts have been raised concerning the mechanism by which high-grade serous adenocarcinomas (HGSCs) arise. Conventionally, HGSC is thought to originate from the ovarian surface epithelium or epithelial inclusion cyst. However, recent data indicate that HGSCs may in fact develop from precursor(More)
A large number monoclonal antibodies (Mo-Abs) to neoplasms have been utilized as diagnostic tools, but they have not yet been fully characterized from the biological point of view. Antibody-dependent cellular cytotoxicity, complement dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC) were investigated in Mo-Abs OC125 and(More)
We investigated the relationship between the serum level of CA125 before a second-look operation (SLO) and SLO findings in 196 patients with adenocarcinoma of the ovary. SLO findings were positive in 38 (19.4%) of 196 patients. The positive rate tended to increase with the clinical stage, but SLO findings were positive even in a patient with stage Ia(More)
