Quantification of residual cryoprotectants and cytotoxicity in thawed bovine ovarian tissues after slow freezing or vitrification.

Study Question: How much residual cryoprotectant remains in thawed/warmed ovarian tissues after slow freezing or vitrification?

Summary Answer: After thawing/warming, at least 60 min of diffusion washing in media was necessary to significantly reduce the residual cryoprotectants in ovarian tissues frozen by slow freezing or vitrification.

What Is Known Already: Ovarian tissue cryopreservation (OTC) by slow freezing has been the conventional method; while the vitrification method has gained popularity for its practicality. The main concern about vitrification is how much potentially toxic residual cryoprotectant remains in the warmed tissues at the time of transplantation.

A multi-institutional survey of the quality of life after treatment for uterine cervical cancer: a comparison between radical radiotherapy and surgery in Japan.

This study aimed to research the post-treatment quality of life (QOL) between radiotherapy (RT)- and operation (OP)-treated early cervical cancer survivors, using separate questionnaires for physicians and patients. We administered an observational questionnaire to patients aged 20-70 years old with Stages IB1-IIB cervical cancer who had undergone RT or OP and without recurrence as outpatients for ≥6 months after treatment. We divided 100 registered patients equally into two treatment groups (n = 50 each).

Value of adjuvant chemotherapy and informed microscopic examination for occult gynecologic cancer detected upon risk-reducing salpingo-oophorectomy after chemotherapy for BRCA1/2-associated breast cancer: a case report.

BRCA1/2 mutation carriers are at high risk for type II ovarian, fallopian tube or peritoneal cancer. Although risk-reducing salpingo-oophorectomy plays an important role in the prevention of these BRCA1/2-associated gynecological cancers, occult ovarian, fallopian tube, or peritoneal cancer is discovered upon risk-reducing salpingo-oophorectomy in 1-4% of BRCA1/2 mutation carriers. Notably, around 30% of BRCA1/2 mutation carriers who undergo risk-reducing salpingo-oophorectomy have undergone adjuvant chemotherapy for breast cancer.

Effectiveness of human papillomavirus vaccination in young Japanese women: a retrospective multi-municipality study.

In Japan, government support for human papillomavirus (HPV) vaccination began in November 2010. However, the mass media repeatedly reported on severe adverse events. The Japanese Ministry of Health, Labor and Welfare suspended proactive recommendations for HPV vaccines in June 2013.

Comparison of ThinPrep Integrated Imager-Assisted Screening versus Manual Screening of ThinPrep Liquid-Based Cytology Specimens.

Objective: The aim of this study was to find out whether ThinPrep Integrated Imager (Hologic Inc.) screening is non-inferior to manual screening in the detection of cervical lesion.

Study Design: For a total of 4,011 ThinPrep Pap test specimens stained by ThinPrep staining, manual screening (Manual arm) and ThinPrep Integrated Imager screening (Imager arm) were performed so as not to be screened by the same cytotechnologist, and the sensitivity and specificity in the detection of cervical lesion were compared using McNemar's test.

The Clinical Features of Recurrent Endometrial Cancer in Japan: Chemotherapy Instead of Radiotherapy as Postoperative Adjuvant Treatment.

Objective: Chemotherapy is a standard adjuvant treatment after primary surgery for endometrial cancer in Japan. We aimed to characterize the clinical features of recurrent endometrial cancer (REC) patients in Japan.

Materials And Methods: We retrospectively reviewed the medical records of 112 REC patients who were primarily treated at 1 of 3 university hospitals in Japan from 2005 to 2012.

Glycan profiling using formalin-fixed, paraffin-embedded tissues: Hippeastrum hybrid lectin is a sensitive biomarker for squamous cell carcinoma of the uterine cervix.

Aim: Glycosylation of proteins is altered in cancer cells and distinctive glycan structures are associated with specific cancers, but little is known about the complete glycan profile of particular tumors. In this study, glycomic analysis of squamous cell carcinoma (SCC) of the uterine cervix was performed to search for useful markers.

Methods: A lectin microarray containing 45 lectins with different binding preferences that covered N- and O-linked glycans was coupled with evanescent field-activated fluorescent detection for glycomic analysis of SCC and normal squamous epithelium (NSE) of the cervix.

Contributions of the Japanese Gynecologic Oncology Group (JGOG) in Improving the Quality of Life in Women With Gynecological Malignancies.

The Japanese Gynecologic Oncology Group (JGOG) is leading Japan in the treatment of gynecological malignancies. The JGOG consists of three treatment committees focusing on uterine cervical cancer, endometrial cancer, and ovarian cancer. Each committee makes efforts to improve treatment and diagnosis.

Proteomic analysis of differential protein expression by brain metastases of gynecological malignancies.

Brain metastases of gynecological malignancies are rare, but the incidence is increasing. Patients with brain metastases have a poor prognosis, therefore early detection and optimal management is necessary. In order to determine a new biomarker, we aimed to identify proteins that associated with brain metastases.

Heat shock protein 27 and p16 immunohistochemistry in cervical intraepithelial neoplasia and squamous cell carcinoma.

Heat shock protein 27 (hsp27) is expressed by squamous cell carcinoma of the uterine cervix. Results from an earlier study by our group indicted that hsp27 may be a diagnostic marker for cervical intraepithelial neoplasia (CIN) and carcinoma. p16 expression is known to be elevated in intraepithelial uterine cervical cancer and grades 2 and 3 lesions (CIN2, CIN3), but has also been reported to be negative in 5-20% of cervical cancer and CIN lesions.
