BACKGROUND Patients with gynecologic cancer have a high risk of venous thromboembolism (VTE) like patients with other cancers. However, there is little information on risk factors for VTE during gynecologic surgery and no uniform preventive strategy. Our objectives were to identify risk factors for perioperative VTE in gynecologic patients and establish(More)
OBJECTIVES In recent years, cancer stem cells (CSCs) have been reported to be correlated with chemoresistance and may also be enriched in side populations (SPs). In this study, the relationship between resistance to paclitaxel (PTX) and cisplatin (CDDP) and side populations was examined in three parental PTX- and CDDP-sensitive ovarian cancer cell lines(More)
The clinical activity of combination of irinotecan (CPT-11) and nedaplatin (NDP) for recurrent patients with uterine cervical cancer was evaluated retrospectively. Intravenous CPT-11 was given at 60 mg/m2 (days 1, 8, 15), followed by NDP 80 mg/m2 (day 1), every 4 weeks. According to the medical records, 29 cases have received this regimen since 2000. Median(More)
A cell line designated HTLS was established from the retroperitoneal liposarcoma. The HTLS line showed stable proliferation without interruption for 2 years and subcultivated over 35 times. The cells were elongated fibrous and spindle in shape, and neoplastic and pleomorphic features. The multinucleated giant cells with he cytoplasm were seen. The cells(More)
So far, there is no recommended evidence-based chemotherapeutic regimen for recurrent or refractory ovarian carcinoma in the guideline. In our institute, combination chemotherapy of CPT-11 and CDDP (CPT-P) was administered for recurrent or refractory ovarian carcinoma patients previously treated with regimens including taxane. In fourteen cases treated with(More)
TGP (thermo-reversible gelation polymer) is a high molecular compound that has so-gel transmitting temperature of 22°C Since solid cancer tissue grows in this polymer three-dimensionally, and fibroblasts scarcely grow in it, TGP is suitable for chemosensitivity assays for solid tumors. In this study, a chemosensitivity test using TGP was applied to(More)
A novel serous surface papillary carcinoma of the ovary (SSPC) cell line, HYKSSPC, was established successfully. Carcinoma cells were obtained from ascitic fluid of a 60-year-old Japanese woman. The population doubling time was 51.4 h. A phase contrast micrograph showed a pavement stone-like arrangement without contact inhibition. The chromosome number(More)
Formation of a fistula to a digestive organ is an extremely rare phenomenon in cases of ovarian carcinoma. We report a case of ovarian clear-cell carcinoma complicated by formation of a sigmoid colon fistula, and review the related literature. A 61-year-old woman, who had undergone hysterectomy and right salpingo-oophorectomy due to myoma and an ovarian(More)
Although radical hysterectomy is the standard surgical treatment for patients with stage IB and II cervical cancer, it does not improve the prognosis of high-risk patients even if postoperative radiotherapy is added. There is therefore a need to establish some other therapeutic regimen. In the present retrospective study, the efficacy of concurrent(More)
BACKGROUND Diagnosis of cancer causes psychological distress. The present study investigated the safety and efficacy of fluvoxamine therapy in gynecologic cancer patients with either adjustment disorder or major depression after cancer was diagnosed. METHODS Screening with the Hospital Anxiety and Depression Scale (HADS) was conducted at least 2 weeks(More)
