Unexpected diagnosis of stage IIA dysgerminoma in streak gonad in a patient with Swyer syndrome: a case report.

Patients with Swyer syndrome, which is also known as 46,XY pure gonadal dysgenesis, are at an increased risk of gonadoblastoma and germ cell tumor. Prophylactic gonadectomy is recommended for these patients. We report a case of stage IIA dysgerminoma arising in a streak gonad in a patient with Swyer syndrome, which was not diagnosable preoperatively and intraoperatively.

Ovarian insufficiency following allogeneic hematopoietic stem cell transplantation.

Ovarian insufficiency is a serious complication for young women who undergo hematopoietic stem cell transplantation (HSCT). Reduced-intensity conditioning (RIC) has been utilized more widely due to its reduced toxicity; however, there is a lack of data concerning ovarian function after HSCT with RIC. We investigated the ovarian function in patients who received HSCT with RIC, compared to those who received myeloablative conditioning (MAC).

Efficacy of dienogest in thinning the endometrium before hysteroscopic surgery.

Study Objective: To investigate the efficacy of administration of dienogest to thin the endometrium before hysteroscopic surgery and to evaluate the surgical outcome.

Design: Retrospective clinical study (Canadian Task Force classification III).

Setting: Community hospital.

Total laparoscopic hysterectomy in patients with previous abdominal surgery.

Purpose: To evaluate the effects of previous abdominal surgery on the feasibility and the safety of total laparoscopic hysterectomy (TLH).

Methods: One hundred seventy-four consecutive patients who underwent TLH in private hospital between February 2008 and December 2009 were retrospectively reviewed. Surgical history, operation time, blood loss, transfusion, conversion to an open surgery, complications and hospital stay were assessed in each patient.

Concurrent weekly nedaplatin, external beam radiotherapy and high-dose-rate brachytherapy in patients with FIGO stage IIIb cervical cancer: a comparison with a cohort treated by radiotherapy alone.

Objectives: The aim of this study was to evaluate whether nedaplatin-based concurrent chemoradiotherapy (CCRT) using high-dose-rate intracavitary brachytherapy (HDR-ICBT) is superior to radiotherapy (RT) alone in patients with FIGO stage IIIb cervical cancer.

Methods: The records of 41 consecutive women treated either with nedaplatin-based CCRT using HDR-ICBT (n = 20) or RT alone (nonrandomized control group, n = 21) for stage IIIb cervical cancer were retrospectively reviewed. The activity and toxicity were compared between the two treatment groups.

Estrogen and raloxifene inhibit the monocytic chemoattractant protein-1-induced migration of human monocytic cells via nongenomic estrogen receptor alpha.

Objective: To investigate the effects of estradiol (E2) and raloxifene on the migration of human monocytic THP-1 cells to endothelium.

Design: A prospective comparative study. THP-1 cells, a human acute monocytic leukemia cell line, were used for the study.

Inhibition of inhibitor of nuclear factor-kappaB phosphorylation increases the efficacy of paclitaxel in in vitro and in vivo ovarian cancer models.

We investigated whether inhibition of nuclear factor-kappaB (NFkappaB) increases the efficacy of paclitaxel in in vitro and in vivo ovarian cancer models. Treatment of paclitaxel-sensitive Caov-3 cells with paclitaxel transiently activated the phosphorylation of Akt, the phosphorylation of IkappaB kinase (IKK), and the phosphorylation of inhibitor of NFkappaB (IkappaBalpha). Paclitaxel also caused a transient increase in NFkappaB activity, followed by a decrease in NFkappaB activity.

Inhibition of NFkappaB increases the efficacy of cisplatin in in vitro and in vivo ovarian cancer models.

Whether or not inhibition of NFkappaB increases the efficacy of cisplatin in in vitro and in vivo ovarian cancer models was investigated. We compared the basal levels of phosphorylation of IkappaBalpha and activity of NFkappaB between cisplatin-sensitive A2780 cells and cisplatin-resistant Caov-3 cells. The basal levels of phosphorylation of IkappaBalpha and activity of NFkappaB in Caov-3 cells were significantly higher than those in A2780 cells.

Estrogen inhibits paclitaxel-induced apoptosis via the phosphorylation of apoptosis signal-regulating kinase 1 in human ovarian cancer cell lines.

The influence of postoperative estrogen replacement therapy on the sensitivity of ovarian cancer to paclitaxel remains elusive. We examined whether estrogen affects paclitaxel-induced apoptosis in the Caov-3 human ovarian cancer cell line, which expresses estrogen receptor. 17beta-Estradiol (E2) significantly reversed the paclitaxel-induced apoptosis and reduction of cell viability, and a highly selective estrogen receptor antagonist, ICI182,780, and a phosphatidylinositol 3-kinase inhibitor, LY294002, attenuated the reversal effect of E2 on paclitaxel-induced apoptosis and reduction of cell viability.

Metastatic ovarian tumors: a review of 64 cases.

Objective: The goal was to review cases of metastatic ovarian tumor with respect to their clinical features.

Methods: Sixty-four patients with pathologically confirmed metastatic ovarian carcinoma, who were treated between 1978 and 2002 at Osaka Medical Center for Cancer and Cardiovascular Diseases (OMCC), were reviewed and the clinical features examined.

Results: We found that metastatic tumors accounted for 21.
