Although preoperative prediction of serous carcinoma was difficult, endometrial cytology had a higher evaluable rate for EC types. Endometrial cytology may complement endometrial biopsy in preoperative women with EC.

The vital role of folic acid is to reduce the risk of having a neonate afflicted with neural tube defects. The prevalence of neural tube defects (myelomeningocele and anencephaly) has been reported in an incomplete form over the last 40 years in Japan. We aimed to evaluate the total number of neural tube defects including those delivered or terminated, to clarify the proportion of those terminated, and to internationally compare their prevalence. Through information on >311 000 deliveries obtained from 262 hospitals/clinics for 2 years of 2014 and 2015, we identified that the rate of total neural tube defects (termination of pregnancy, live births and stillbirths) was 8.29 per 10 000 deliveries for the year 2014 and was 8.72 for 2015, which were 1.5 and 1.6 times higher than the respective values (live births and stillbirths) reported. It is also observed that the ratio of the total number of myelomeningocele (termination of pregnancy, live births, and stillbirths) to that of anencephaly was approximately 1:1.2, that a half of pregnancies afflicted with neural tube defects were terminated, and that the proportion of termination of pregnancy due to myelomeningocele and due to anencephaly was 20% and 80%, respectively. Internationally, the real prevalence of neural tube defects in Japan was comparatively high, ranking fifth among the seven developed countries. In conclusion, the real prevalence of total neural tube defects was approximately 1.5 times higher than that currently reported by the Japan Association of Obstetricians and Gynecologists.

Objective: The prognosis of ovarian cancer has improved because of platinum-and taxanecontaining chemotherapy. We investigated the 5-year disease-specific overall survival and prognostic factors of patients with advanced ovarian cancer to elucidate the change in clinical course of ovarian cancer with the advance of chemotherapy for patients who developed relapse in the era before the addition of molecular targeting therapy. Methods: We reviewed the clinical course of 134 patients with advanced ovarian cancer (FIGO Stage III and IV) treated in the past 11 years (1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010). We classified the patients into two groups: those who had been diagnosed with ovarian cancer from 1999 to 2005 (Group A) and those who had been diagnosed from 2006 to 2010 (Group B). We compared the 5-year diseasespecific overall survival and median survival rates between these two groups. We also investigated the prognostic factors of 104 patients who developed relapse. Results: The 5-year disease-specific overall survival rate was significantly higher in Group B than A (67.0% vs. 38.6%; P = 0.032). Chemotherapy containing pegylated liposomal doxorubicin hydrochloride, non-clear cell adenocarcinoma and intestinal resection were independent prognostic factors. Conclusions: The induction of new chemotherapeutic drugs and the increased variation of secondor third-line chemotherapy affected the improvement in overall survival of patients with advanced epithelial ovarian cancer.
