Abstract
OBJECTIVE To examine the association between intrauterine manipulator use and pathological factors and oncologic outcomes in patients with endometrial cancer who had laparoscopic hysterectomy in Japan. METHODS This was a nationwide retrospective cohort study of the tumor registry of the Japan Society of Obstetrics and Gynecology. Study population was 3846 patients who had laparoscopic hysterectomy for endometrial cancer from January 2015 to December 2017. An automated 1-to-1 propensity score matching with preoperative and intraoperative demographics was performed to assess postoperative pathological factors associated with the intrauterine manipulator. Survival outcomes were assessed by accounting for possible pathological mediators related to intrauterine manipulator use. RESULTS Most patients had preoperative stage I disease (96.5%) and grade 1-2 endometrioid tumors (81.9%). During the study period, 1607 (41.8%) patients had intrauterine manipulator use and 2239 (58.2%) patients did not. In the matched cohort, the incidences of lymphovascular space invasion in the hysterectomy specimen were 17.8% in the intrauterine manipulator group and 13.3% in the non-manipulator group. Intrauterine manipulator use was associated with a 35% increased odds of lymphovascular space invasion (adjusted odds ratio 1.35, 95% confidence interval (CI) 1.08 to 1.69). The incidences of malignant cells identified in the pelvic peritoneal cytologic sample at hysterectomy were 10.8% for the intrauterine manipulator group and 6.4% for the non-manipulator group. Intrauterine manipulator use was associated with a 77% increased odds of malignant peritoneal cytology (adjusted odds ratio 1.77, 95% Cl 1.29 to 2.31). The 5 year overall survival rates were 94.2% for the intrauterine manipulator group and 96.6% for the non-manipulator group (hazard ratio (HR) 1.64, 95% Cl 1.12 to 2.39). Possible pathological mediators accounted HR was 1.36 (95%Cl 0.93 to 2.00). CONCLUSION This nationwide analysis of predominantly early stage, low-grade endometrial cancer in Japan suggested that intrauterine manipulator use during laparoscopic hysterectomy for endometrial cancer may be associated with an increased risk of lymphovascular space invasion and malignant peritoneal cytology. Possible mediator effects of intrauterine manipulator use on survival warrant further investigation, especially with a prospective setting.

Abstract
In association with an update of the Japan Society of Gynecologic Oncology clinical practice guidelines for endometrial cancer in 2023, a systematic review was conducted about the therapeutic benefit of adjuvant therapy on patients with early-stage endometrial carcinoma, who presented positive peritoneal cytology (PPC) without the risk factors for recurrence. The systematic review only included two eligible retrospective studies. Both studies included patients with risk factors for recurrence. A nationwide study in the United States reported that adjuvant chemotherapy was associated with the reduced risk of death among patients with stages I-II endometrial cancer with PPC by multivariate, propensity score-adjusted analysis. Another single-center study in Japan reported no association between adjuvant chemotherapy and relapse-free survival among patients with stage IA endometrial cancer by univariate analysis. This systematic review identified that evidence was limited with conflicting results. Continuous evaluation is warranted to address this clinical question.

Abstract
OBJECTIVE This study elucidated the efficacy of Relugolix (REL) on the reduction of uterine volume and clinical symptoms for the treatment of adenomyosis. METHODS We conducted a retrospective cohort study of patients who received REL (40 mg for about 20 weeks) and who underwent a hysterectomy for adenomyosis or fibroids. We divided patients into two groups: adenomyosis coexisting with fibroids (Group A) and fibroids only (Group B); the groups were determined by a postoperative pathological examination. The primary end points were the percent reduction in uterine volume, adenomyotic lesion, and the largest fibroid volume at week 16. The secondary end points were the rate of amenorrhea, pelvic pain, and anemia at week 12. RESULTS A total of 56 patients participated in the current study: 20 in Group A and 36 in Group B. Regarding the largest fibroid volume, there was no significant difference between the two groups. Uterine volume after REL treatment was significantly decreased in Group A (43%), as compared to Group B (27%) (p = .00972), In Group A, adenomyotic lesion was decreased by 61%. Irrespective of the group, adenomyosis showed a significant reduction compared to uterine fibroids (p < .001). There was no statistically significant difference in the mitigation of symptoms (amenorrhea, pelvic pain, and anemia) between the two groups. CONCLUSIONS REL is more effective in reducing adenomyotic lesion than uterine fibroids and in relieving symptoms (amenorrhea, pelvic pain, and anemia). It can be expected that REL will also be used as a preoperative treatment for adenomyosis.

Abstract
AIMS/INTRODUCTION To evaluate the efficacy of sensor-augmented pump (SAP) for improving obstetric and neonatal outcomes among pregnant women with type 1 diabetes mellitus by comparing it with continuous subcutaneous insulin infusion plus self-monitoring of blood glucose (continuous subcutaneous insulin infusion [CSII]/SMBG). MATERIALS AND METHODS This retrospective cohort study included 40 cases of pregnancy complicated by type 1 diabetes mellitus treated with SAP (SAP group), and 29 cases of pregnancy complicated by type 1 diabetes mellitus treated with CSII/SMBG (CSII/SMBG group). The obstetric and neonatal outcomes were compared between the two groups. RESULTS The median of the glycoalbumin levels in the first (18.8% vs 20.9%; P < 0.05) and second (15.4% vs 18.0%; P < 0.05) trimesters, the hemoglobin A1c levels in the peripartum period (6.1% vs 6.5%; P < 0.05) and the standard deviation score of birthweights (0.36 vs 1.52; P < 0.05) were significantly lower in the SAP group than in the CSII/SMBG group. The incidence rate of large for gestational age newborns was significantly lower in the SAP group than in the CSII/SMBG group (27.5% vs 65.5%; P < 0.05). No significant differences in the incidence rates of hypertensive disorders of pregnancy, small for gestational age, respiratory distress syndrome, neonatal hypoglycemia, hypervolemia and hyperbilirubinemia were observed between the groups. CONCLUSION The present study showed that SAP therapy is more effective in preventing large for gestational age newborns in pregnant women with type 1 diabetes mellitus than CSII/SMBG.

Abstract
INTRODUCTION AND IMPORTANCE A case of Low-grade endometrial stromal sarcoma (LG-ESS) invading the great vessels is rare. CASE PRESENTATION A 34-year-old female who had no past history presented to a previous hospital with abdominal distension. Magnetic resonance imaging revealed a 15 cm pelvic mass beside the uterus, and only the pelvic mass was removed at the surgery. The tumor was judged to be a LG-ESS. The patient chose to be observed to preserve her fertility, and no adjuvant treatment was undertaken. Two years later, she was referred to our hospital due to recurrence of the pelvic mass. Enhanced computed tomography revealed a large tumor in the vena cava which extended from the left internal iliac vein and which originated from the pelvic tumor. An operation was performed by a multidisciplinary team. Complete resection of the tumor was achieved with a radical hysterectomy, bilateral salpingo-oophorectomy, removal of recurrent pelvic masses and the intravascular tumor. We diagnosed a recurrence of LG-ESS. She received a postoperative adjuvant therapy of LG-ESS. CLINICAL DISCUSSION Patients with fertility-sparing treatment had higher recurrence rates. In cases of tumor intravenous extension, we should make every effort to extract the tumor to avoid sudden death. CONCLUSION This case highlights the importance of a multidisciplinary approach in treating this rare tumor with intravascular extension. In particular, patients with LG-ESS who receive fertility-sparing surgery should undertake postoperative chemotherapy or radiotherapy in order to reduce the risk of recurrence, as was in this case.

Abstract
AIM Minimally invasive surgery (MIS) has been introduced as an alternative to more radical surgical procedures. The Japan Society of Gynecologic and Obstetric Endoscopy and Minimally Invasive Therapy conducted a cross-sectional questionnaire survey to ascertain the status of MIS for endometrial cancer. METHODS The survey was conducted between May 10 and June 30, 2022. The questionnaire included information on personal attributes, academic affiliations, qualifications, hysterectomies, and intraoperative procedures performed. RESULTS The total number of questionnaire respondents was 436 (9.2% of the membership). The hysterectomy methods and percentage performed were as follows: simple total hysterectomy (equivalent to benign surgery), 3%; simple total hysterectomy with care to avoid shaving the cervix, 31%; extended total hysterectomy, 48%; and modified radical hysterectomy, 15%. An analysis of hysterectomies performed using MIS for endometrial cancer by qualified gynecologists of endoscopy or board-certified gynecologic oncologists showed a tendency not to choose simple total hysterectomy compared to the gynecologists who did not hold certification (p = 0.019, p = 0.045, and p = 0.010, respectively). Additionally, 67% of respondents did not use uterine manipulators, and 59% of the respondents did not perform lymph node dissection following the guidelines for treating endometrial cancer in Japan. CONCLUSION This study provided the current status of MIS for endometrial cancer in Japan. The hysterectomy method, use of uterine manipulators, and criteria for omitting lymph node dissection were generally in agreement with the guidelines. Currently, an extra-fascial simple hysterectomy, including at least not shaving the cervix, was a major method for early invasive endometrial cancer using MIS.

Abstract
Ovarian cancer (OC) is a refractory cancer that shows recurrence due to the acquisition of resistance to anticancer drugs, including cisplatin. However, the molecular mechanism underlying the acquisition of cisplatin resistance by cancer cells remains largely unknown. In the present study, two sets of ovarian endometrioid carcinoma cell lines were used: The parental A2780 cell line, the OVK18 cell line, and their derived cisplatin‑resistant cells. It was found that cisplatin could induce ferroptosis in these parental cells by enhancing mitochondrial membrane potential and lipid peroxidation as assessed by flow cytometric analysis, and that expression of Ferredoxin1 (Fdx1), an iron‑sulfur protein localized to the mitochondria, could be upregulated in cisplatin‑resistant cells in the absence of cisplatin. Intriguingly, it was shown that the siRNA‑mediated depletion of Fdx1 in cisplatin‑resistant cells resulted in enhanced ferroptosis by increasing the mitochondrial membrane potential and lipid peroxidation induced by cisplatin. By examining Fdx1 expression with immunohistochemical analysis in clinical specimens from patients with OC, higher expression of Fdx1 was detected in cisplatin‑resistant specimens than in cisplatin‑sensitive specimens. Collectively, these results indicated that Fdx1 may be a novel and suitable diagnostic/prognostic marker and therapeutic molecular target for the treatment of cisplatin‑resistant OC.

Abstract
OBJECTIVE Owing to the potential benefits of minimally invasive hysterectomy for endometrial cancer, the practice pattern has recently shifted in Japan. This study examined the trends in minimally invasive surgery (MIS) in patients with endometrial cancer in Japan. METHODS This retrospective observational study examined the Japan Society of Obstetrics and Gynecology Tumor Registry database between 2015-2019. This study examined the time-specific proportion change and predictors of MIS use in initial endometrial cancer treatment in Japan, and compared it with the use of abdominal surgery. Additionally, the association between hospital surgical treatment volume and MIS use was examined. RESULTS A total of 14,059 patients (26.5%) underwent minimally invasive hysterectomy, and 39,070 patients (73.5%) underwent abdominal hysterectomy in the study period. Patients who underwent MIS were more likely to be treated at high-volume centers, younger, central, or western Japan residents, registered in recent years, and had a tumor with stage I disease, type 1 histology, and less myometrial invasion (all adjusted p<0.05). The proportion of MIS treatments increased from 19.1% in 2015 to 34.3% in 2019 (p<0.001). On multivariable analysis, treatment at high-volume centers was a contributing factor for MIS (adjusted odds ratio=3.85; 95% confidence interval=3.44-4.30). MIS at high-volume centers increased significantly from 24.8% to 41.0% (p<0.001) during the study period, whereas MIS at low-volume centers remained at median 8.8%. CONCLUSION MIS has increased significantly in recent years, accounting for nearly 34% of surgical management of endometrial cancer in Japan. High-volume treatment centers take the lead in performing MIS.

Abstract
Intramural pregnancy is a rare form of ectopic pregnancy. It is defined by a gestation within the uterine wall, completely surrounded by myometrium and separated from the uterine cavity and the fallopian tube. We report a rare case of intramural ectopic pregnancy. If a patient has a history of intrauterine surgery or myomectomy, the possibility of intramural pregnancy, although rare, should not be ruled out.

Abstract
Ovarian cancer (OC) is the fifth most common cancer of female cancer death and leading cause of lethal gynecological cancers. High-grade serous ovarian carcinoma (HGSOC) is an aggressive malignancy that is rapidly fatal. Many cases of OC show amplification of the 8q24 chromosomal region, which contains the well-known oncogene MYC. Although MYC amplification is more frequently observed in OCs than in other tumor types, due to the large size of the 8q24 amplicon, the functions of the vast majority of the genes it contains are still unknown. The TIGD5 gene is located at 8q24.3 and encodes a nuclear protein with a DNA-binding motif, but its precise role is obscure. We show here that TIGD5 often co-amplifies with MYC in OCs, and that OC patients with high TIGD5 mRNA expression have a poor prognosis. However, we also found that TIGD5 overexpression in ovarian cancer cell lines unexpectedly suppressed their growth, adhesion, and invasion in vitro, and also reduced tumor growth in xenografted nude mice in vivo. Thus, our work suggests that TIGD5 may in fact operate as a tumor suppressor in OCs rather than as an oncogene.

Abstract
AIM To evaluate the impact on urodynamic results between the laparoscopic nerve-sparing radical hysterectomy (LRH) following a step-by-step procedure and abdominal nerve-sparing radical hysterectomy (ARH) for patients with uterine cervical cancer. METHODS This retrospective study enrolled 76 patients with cervical cancer: 35 in the LRH group and 41 in the ARH group. We analyzed their postoperative bladder function in a urodynamics study and examined the volume of resected pelvic nerves contained in parametrial sections using S-100 antibody staining. RESULTS Estimated blood loss and hospital stay after operation for the LRH group were significantly better than those in the ARH group (p < 0.0001). As well, the number of harvested lymph nodes was significantly higher in the LRH group (p = 0.044). There was no difference in perioperative complications between the two groups in this study. The 5-year disease-free survival rates and overall survival rates were 91.2% and 94.0% in the LRH group and 87.8% and 95.1% in the ARH group, both respectively. Although the median residual urine volume were no statistical differences between the LRH group and the ARH group, the recovery of postoperative bladder function (uroflowmetry) in the LRH group rapidly reached presurgery levels at 1 month, and the LRH group had a smaller number of s-100 antibody stained nerves contained the parametrial sections. CONCLUSION We demonstrated that LRH following a step-by-step procedure could achieve a higher level of prevention of damage to the bladder branch of the pelvic splanchnic nerve plexus and thus restore bladder function more rapidly.

Abstract
Human papillomavirus (HPV) vaccine has been used to prevent chronic HPV infection, which accounts for cervical cancer. Japanese Ministry of Health, Labor and Welfare (MHLW) conducted an HPV vaccination campaign in 2010 and the Obstetrical Gynecological Society of Osaka initiated a multicenter, prospective cohort study in Osaka, Japan – OCEAN (Osaka Clinical resEArch of HPV vacciNe) study – to investigate the oncogenic HPV prevalence and the long-term protection rate of HPV vaccine. A total of 2814 participants were enrolled on their visit for HPV vaccination between 12 and 18 years old. Among them, 102 participants received HPV/Pap co-test as primary cancer screening at the age of 20–21. We compared the prevalence in two groups (the vaccinated and the unvaccinated group). HPV infection ratio was significantly lower in the vaccinated group compared to the unvaccinated (12.9% vs. 19.7%; p = .04). In particular, HPV 16 and 18 were not detected in the vaccinated group, while 4.9% of participants in the unvaccinated group were infected (p = .001), suggesting that vaccination provided effective protection against high-risk types of HPV. The cross-protection effect of HPV vaccines was also observed against HPV 31, 45, and 52. Although HPV vaccines were not contributed to the reduction of cervical intraepithelial neoplasia 1 (CIN) (p = .28), CIN2 or worse was not observed in vaccinated group. Our research showed that at the age of 20–21, HPV vaccine inhibited the infection of high-risk HPV and had impacted on the development to CIN2 or worse in Japan.

Abstract
Radiotherapy (RT) is used to manage cervical cancer, and pelvic insufficiency fracture (PIF) is known as a late complication of RT. The present study identified risk factors for PIF after radiotherapy for cervical cancer, and investigated its incidence rate. It also considered the usefulness of positron emission tomography/magnetic resonance imaging (PET/MRI) in PIF diagnosis. A total of 149 patients with cervical cancer who received definitive or adjuvant RT with/without concurrent chemotherapy between January 2013 and December 2018 were investigated in the present study and followed up for more than one month after RT at Kobe University Hospital. The median follow-up period was 32 months (range, 1-87 months), and the median age of all patients was 66 years (age range, 34-90 years). Computed tomography (CT), MRI, PET/CT or PET/MRI were used for image examination. Among the 149 patients, 31 (20.8%) developed PIF. The median age of these patients was 69 years (age range, 44-87 years). Univariate analysis using the log-rank test demonstrated that age (≥60 years) was significantly associated with PIF. The median maximum standardized uptake value of PIF sites on PET/CT was 4.32 (range, 3.04-4.81), and that on PET/MRI was 3.97 (range, 1.21-5.96) (P=0.162). Notably, the detection time of PIF by PET/MRI was significantly earlier compared with PET/CT (P<0.05). The incidence of PIF after RT for cervical cancer was 20.8%, and age was significantly associated with risk factors for such fractures. Taken together, these results suggest that PET/MRI, which offers the advantage of decreased radiation exposure to the patient, is useful for diagnosing PIF and can detect it earlier than PET/CT imaging.

Abstract
OBJECTIVE The purpose of our study was to conduct a detailed survey of radical hysterectomy in Japanese patients with early-stage cervical cancer, and to compare oncologic outcomes between open and minimally invasive radical hysterectomy. METHODS In Japan during 2015, the medical records of 929 patients with FIGO stage IB1 and IIA disease treated with radical hysterectomy were retrospectively reviewed. We assessed patients' characteristics, disease-free survival (DFS), overall survival (OS) and prognostic factors for survival. RESULTS The median patient age was 44 (20-80) years. Most patients (94.4%) had stage IB1 disease. Of the patients who underwent radical hysterectomy, 91.2% underwent open surgery and 8.8% underwent minimally invasive surgery (MIS). The median follow-up period was 40.8 months (range, 0.49-51.1 months). The rate of DFS and OS at 4 years in all patients was 88.3% and 96.4%, respectively. Multivariate analysis identified age (≥ 47), adenocarcinoma histology, tumor size (≥ 2 cm), parametrial invasion, positive lymph node metastasis and institutional accreditation as independent predictors of recurrence, and adenocarcinoma, other cell types, and positive lymph node metastasis as independent predictors of death. Oncologic outcomes in all patients were similar between open and MIS, including DFS and OS. CONCLUSION The survival rate of the Japanese patients underwent radical hysterectomy for early-stage cervical cancer was favorable. No significant differences were observed for DFS and OS between open and MIS performed by a limited number of surgeons at a limited number of facilities in Japan. Further investigations are required to identify the appropriate patients might benefit from MIS.

Abstract
Placental mesenchymal dysplasia (PMD) is a rare placental abnormality that is closely related to severe pregnancy complications. A 27-year-old woman with fetal growth restriction and placenta previa was referred to a university hospital at 22 gestational weeks (GW). She was suspected of having a twin pregnancy with a complete or partial hydatidiform mole and coexisting normal live fetus, because two separate placentas, an enlarged one with multiple cystic lesions and a normal one, were shown on ultrasound examinations. At 27 GW, she experienced a sudden intrauterine fetal death (IUFD) after bleeding due to placenta previa, despite confirmation of fetal well-being at 2 h before bleeding. After delivery, histopathological examination confirmed the diagnosis of PMD. This is the first documented case of a woman with PMD and placenta previa who had a sudden IUFD after bleeding. Patients with both PMD and placenta previa should be considered at extremely high risk for IUFD.

INTRODUCTION Placenta accreta spectrum (PAS) is a life-threating obstetric complication, and prenatal prediction of PAS can decrease maternal morbidity and mortality. The aim of this prospective cohort study was to determine the clinical factors associated with PAS. METHODS Pregnant women who delivered at a university hospital were enrolled. Clinical data were collected from medical records, and logistic regression analyses were performed to determine which clinical factors were associated with PAS. RESULTS Eighty-seven (2.1%) of the 4146 pregnant women experienced PAS. Multivariable analyses revealed that a prior history of cesarean section (CS) (OR 3.3; 95% CI 1.9-5.7; p < 0.01), dilation and curettage (D&C) (OR 2.8; 95% CI 1.7-4.6; p < 0.01), hysteroscopic surgery (OR 5.7; 95% CI 2.3-14.4; p < 0.01), uterine artery embolization (UAE) (OR 44.1; 95% CI 13.8-141.0; p < 0.01), current pregnancy via assisted reproductive technology (ART) (OR 4.1; 95% CI 2.4-7.1; p < 0.01), and the presence of placenta previa in the current pregnancy (OR 13.1; 95% CI 7.9-21.8; p < 0.01) were independently associated with the occurrence of PAS. CONCLUSION Pregnant women who have a prior history of CS, D&C, hysteroscopic surgery, UAE, current pregnancy via ART, and the presence of placenta previa in the current pregnancy are high risk for PAS.

Abstract
A 40-year-old primigravida woman with a monochorionic-triamniotic (MT) triplet pregnancy was hospitalized due to threatened abortion at 16 gestational weeks. Polyhydramnios in two fetuses and oligohydramnios in the third supported a diagnosis of feto-fetal transfusion syndrome (FFTS) at 23 weeks and 3 days of gestation. Severe dyspnea and liver dysfunction required intensive care unit admission and mechanical ventilation support, and abdominal compartment syndrome (ACS) caused by polyhydramnios was clinically diagnosed. When her general condition was not improved regardless of intensive care, the patient delivered the three fetuses by cesarean section at 23 weeks and 5 days gestation. Abdominal decompression was achieved with delivery, and the patient was discharged 13 days after operation without morbidity. This is the first case report of ACS caused by FFTS in a MT triplet pregnancy resulting in extremely preterm birth.

Abstract
BACKGROUND Serous endometrial intraepithelial carcinoma (SEIC) is now considered to represent an early stage of uterine serous carcinoma (USC). It is an intraepithelial lesion but has been reported to cause extrauterine metastases. We report a case of SEIC with serous ovarian carcinoma and lymph node metastasis. CASE PRESENTATION A 57-year-old post-menopausal woman (gravida 3, para 2, SA1) was referred to our hospital with lower abdominal pain. An ultrasound and MRI showed that the ovary had swollen to 8 cm in size and had a solid lesion. The uterus was normal. The patient underwent exploratory laparoscopy on the suspicion of torsion of the ovarian tumor. Intraoperative findings showed a right ovarian tumor, but no ovarian tumor torsion was observed. A small amount of bloody ascites was found in the Douglas fossa, and bleeding was observed from the tumor itself. A right salpingo-oophorectomy was then performed. Histopathological results revealed a high-grade serous carcinoma. Forty days after the first surgery, we performed a staging laparotomy: a total abdominal hysterectomy, left salpingo-oophorectomy, systematic pelvic and paraaortic lymphadenectomy, and a partial omentectomy. A complete cytoreduction was achieved. In the pathological examination, the invasion of the serous carcinoma was observed in the left ovarian ligament, and lymph node metastasis was found in the paraaortic lymph nodes. Atypical columnar cells formed irregular papillary lesions which had proliferated in the endometrium, and this was diagnosed as SEIC. The final diagnosis was serous ovarian cancer, FIGO stage IIIA1(ii), pT2bN1M0, with SEIC. CONCLUSION We report a case of SEIC with synchronous serous carcinoma of the adnexa uteri. Both were serous carcinomas and, thus, it was difficult to identify the primary lesion. The distinction between metastatic cancer and two independent primary tumors is important for an accurate diagnosis and tumor staging. Histological diagnostic criteria remain controversial, and further development of a method for differentiating between both diseases is required.

Abstract
AIM To evaluate whether embryo selection using the early embryo viability assessment (EEVA) score increases the ongoing pregnancy rate of in vitro fertilization and intracytoplasmic sperm injection patients. METHODS One hundred eighty-one patients whose serum anti mullerian hormone (AMH) level was greater than 0.5 ng/μL were enrolled in the study. All patients received oocyte retrieval repeatedly from June 2017 to January 2019. Transferred embryos were selected using the EEVA score and Veeck's criteria. We investigated the blastocyst rate according to the EEVA score and Veeck's criteria and also evaluated the clinical outcome following embryo transfer of the blastocysts. RESULTS Blastocyst development rate (48.7%) and high-quality blastocyst (42.4%) of Veeck 1 was statistically higher than others. The blastocyst rate (71.4%) and high-quality blastocyst rate (60.0%) for EEVA 1 was the highest, and a correlation between the EEVA score and the blastocyst rate was also identified in cases younger than 40 years. Blastocyst rate of EEVA 1 + 2 (69.8% 208/298) was statistically higher than that of Veeck 1 + 2 (40.1% 317/791) (p < 0.05) and high-quality blastocyst rate of EEVA 1 + 2 (50.0% 104/208) was also higher than that of Veeck 1 + 2 (36.6% 117/320) (p < 0.05). However, there was a significant correlation between EEVA and the pregnancy rate and pregnancy rate of EEVA 1 + 2 showed no statistical difference compared with Veeck 1 + 2. CONCLUSIONS Although it remains to be answered whether a computer can substitute Veeck's classification, the EEVA score could be a viable alternative to predict the blastocyst rate and to select those high-potential embryos that improve the pregnancy rate.

Abstract
INTRODUCTION In Japan, two groups of women, HPV vaccinated and unvaccinated, are approaching age 20, when they should begin cervical cancer screening. To improve Japan's current poor cervical cancer screening rate, we need to know how these women are thinking about screening. METHODS We conducted an internet survey of 20-y-old women, exploring their understanding of HPV and cervical cancer screening. We then gave them leaflets with basic information about HPV and cervical cancer, stressing the importance of early detection by screening. We analyzed the leaflet's effects on their attitudes based on their vaccination status. RESULTS Our study of 618 women found a significantly higher intention for engagement for cervical cancer screening in women HPV-vaccinated as teenagers (29% versus 17%). They were also more aware that: (1) HPV is transmitted by sexual intercourse (49.1% versus 39.2%); (2) the HPV vaccine prevents cervical cancer (49.0% to 34.0%); and (3) the appropriate cervical cancer screening interval is every 2 y (63.3% versus 56.2%). Women in both groups responded well to the leaflet, with significant improvements in intention to receive screening. However, 65%-67% were not swayed. DISCUSSION HPV-vaccinated women were more knowledgeable about cervical cancer and had a greater intention to receive screening. Our educational leaflet was moderately effective in both groups for increasing intentions to screen, but the majority in both groups were still resistant to screening. CONCLUSION Japan needs to develop more effective educational programs and tools to vigorously impart the importance of cervical cancer screening.

Abstract
Cervical cancer is the fourth-most prevalent malignancy in women. For advanced cervical cancer, radiotherapy is a major treatment. Micro RNAs (miRNAs) are small, noncoding RNAs that negatively regulate the target gene expression posttranscriptionally. miR-22 is frequently downregulated in various cancers including cervical cancer, and is associated with a poor prognosis in cervical cancer. Exosomes are small endosomally secreted vesicles that carry components such as proteins, messenger RNA (mRNA), DNA and miRNA. We investigated whether or not exosomes can efficiently deliver miR-22 to recipient cervical cancer cells and affect the gene expression in the cells, as well as assessed the role of exosomal miR-22 in radiosensitivity. Exosomes containing high levels of miR-22 were extracted by ultracentrifugation and then characterized by Western blotting, a nanoparticle tracking analysis and electron microscopy. The high presence of miR-22 in the exosome was confirmed by real-time polymerase chain reaction. After the administration of the collected exosomal miR-22 to SKG-II and C4-I cervical cancer cells, the level of miR-22 in the cells was significantly increased, indicating the absorption of the exosomal miR-22. When miR-22 encapsulated in exosomes was administered to the SKG-II cells, the level of c-Myc binding protein (MYCBP) and human telomerase reverse transcriptase (hTERT) was significantly decreased in correlation with increased radiosensitivity determined by a clonogenic assay. Taken together, these results suggest that the administration of exosomal miR-22 may be a novel drug delivery system for cervical cancer radiotherapy.

Abstract
BACKGROUND The development of perforations or fistulas in the Gastrointestinal (GI) tract or genitourinary (GU) system is a serious adverse effect of bevacizumab. The aim of this study was to investigate the incidences of these GI/GU events as well as their association with previous radiotherapy (RT) in Japanese women with cervical cancer. METHODS We conducted a written questionnaire survey among 14 gynecological institutions belonging to the Oncology Research Committee of the Obstetrical and Gynecological Society of Kinki District, Japan. The severity of GI/GU events was classified according to the National Cancer Institute's Common Terminology Criteria for Adverse Events version 5.0. All data were extracted from survey responses and maintained in an Excel spreadsheet and summarized using descriptive statistics. RESULTS The information of 224 Japanese women with cervical cancer (152 recurrent and 72 advanced) who were treated with bevacizumab-containing chemotherapy was collected from 14 institutions. Of these, 65% had been previously treated with RT. GI/GU events of any grade developed in 25 (11.2%) patients, leading directly to death in 3 (1.3%) patients. When compared, the incidence of GI/GU events was higher in recurrent disease patients than in advanced disease patients (13.8% vs 5.6%, p = 0.0728). When examined according to the history of RT, the incidence of GI/GU events was greater in patients with a history of RT than in those without (14.5% vs 5.1%, p = 0.044). CONCLUSION More than 10% of patients experience GI/GU events during or after receiving bevacizumab-containing chemotherapies. Prior RT is a risk factor for bevacizumab-associated GI/GU events.

Abstract
Background MicroRNAs (miRNAs) have been implicated to play a vital role in development, differentiation, cell proliferation and apoptosis. However, which miRNAs are actually associated with endometriosis-associated ovarian cancer remains controversial. Methods Serum and ascites samples were obtained from all patients. Serum samples from 5 cases of ovarian endometrioma and endometriosis-associated ovarian cancer each were submitted for comprehensive miRNA microarray profiling. We investigated the differential expression of miRNAs between the two groups to confirm the pivotal role of miRNAs. Quantitative reverse transcription-polymerase chain reaction validation of five selected miRNAs [miR-92a-3p, miR-486-5p, miR-4484, miR-6821-5p, and miR-7108-5p] was performed, and miR-486-5p expression analysis was followed by proliferation and wound healing assays, depending on the expression of miR-486-5p. Result miR-486-5p expression in serum and ascites samples from endometriosis-associated ovarian cancer patients was significantly higher than that from ovarian endometrioma patients. Moreover, the miR-486-5p level in serum and ascites samples was significantly correlated with the severity of the endometriosis. The upregulation of miR-486-5p in immortalized ovarian endometrioma cells significantly increased proliferation and migration. In contrast, the downregulation of miR-486-5p in these cells significantly decreased proliferation and migration. Conclusion miR-486-5p might function as an oncogenic miRNA in endometriosis-associated ovarian cancer and could be a noninvasive biomarker to prospect the severity of ovarian endometrioma.

Abstract
MicroRNAs (miRs) influence the expression of their target genes post-transcriptionally and serve an important role in multiple cellular processes. The downregulation of miR-22 is associated with a poor prognosis in cervical cancer. However, the mechanisms underlying miR-22-mediated gene regulation and its function are yet to be elucidated. In the present study, the effect of miR-22 expression on the radiosensitivity of cervical cancer was investigated. First, miR-22 was either up- or downregulated to evaluate the regulation of the MYC-binding protein (MYCBP) in four cervical cancer cell lines (C-4I, SKG-II and SiHa). Notably, MYCBP expression was inversely associated with miR-22 induction. A dual-luciferase reporter gene assay revealed that miR-22 directly targets the MYCBP 3'-untranslated region. Subsequently, the level of human telomerase reverse transcriptase component (hTERT; an E-box-containing c-Myc target gene) was analyzed after the up- or downregulation of miR-22. Notably, miR-22-mediated repression of MYCBP reduced hTERT expression. In addition, the influence of miR-22 on radiosensitivity in C-4I, SKG-II and SiHa cells was examined using a clonogenic assay and in mouse xenograft models. Upregulation of miR-22 was associated with increased radiosensitivity. Furthermore, lentiviral transduction of miR-22 reduced the Ki-67 index while increasing the TUNEL index in xenograft tissue. The current findings indicate the potential utility of miR-22 in radiotherapy for cervical cancer.

Abstract
CD24, which is upregulated in several human malignancies, is related to Epithelial-mesenchymal-transition (EMT) and has characteristics of cancer stem-like cells, especially in cisplatin-resistant ovarian carcinoma cells. Drug delivery systems represent a promising therapeutic approach for diseases with treatment resistance, and the present study investigated a novel CD24-targeted drug delivery system for advanced ovarian carcinoma. We produced liposomal cisplatin with a red fluorescent substance - cyanine 5.5 (GL-CDDP-Cy5.5). In order to target CD24-positive cells, an anti-CD24 monoclonal antibody was modified to the above drug (CD24-GL-CDDP-Cy5.5). Specific uptake of CD24-GL-CDDP-Cy5.5 was confirmed using a therapeutically resistant ovarian cancer cell line, Caov-3 cells. Antitumor effects of CD24-GL-CDDP-Cy5.5 were then evaluated in Caov-3 ×enograft mice. CD24-GL-CDDP-Cy5.5 showed more specific uptake by flow cytometry than GL-CDDP-Cy5.5. In xenograft mice, GL-CDDP-Cy5.5 and CD24-GL-CDDP-Cy5.5 treatment had significantly higher platinum concentration in disseminated tumor cells than cisplatin (P<0.05). Moreover, CD24-GL-CDDP-Cy5.5 suppressed tumor growth and prolonged survival time compared with other treatments. Median survival times of the control, cisplatin, GL-CDDP-Cy5.5 and CD24-GL-CDDP-Cy5.5 groups were 37, 36, 46 and 54 days after inoculation, respectively. Immunohistochemical analysis showed that CD24-GL-CDDP-Cy5.5 treatment, compared with GL-CDDP-Cy5.5, decreased the number of CD24-positive cells and suppressed the EMT phenomenon significantly (P<0.05). The present study demonstrated that CD24-GL-CDDP-Cy5.5, compared with other treatments, improved therapeutic efficacy. The present results suggested the potential for targeting anticancer therapeutics for CD24-positive cells to prevent disease progression.

Abstract
OBJECTIVE We report a balloon-occluded arterial infusion therapy with an original four-lumen double-balloon catheter (4L-DB) which allows for the efficient injection of an anticancer agent at a high concentration to the target spot for patients with locally advanced uterine cervical cancer. METHODS One hundred and forty-three patients with locally advanced cervical cancer treated with neoadjuvant intra-arterial chemotherapy (NAIAC) or a primary radical hysterectomy (PRH) were retrospectively assessed. The patients in the NAIAC group received irinotecan 70 mg/m2 intravenously on day 1 and 8 and cisplatin 70 mg/m2 intra-arterially using the 4L-DB on day 2 of a 21-day course, and two courses were performed in principle. The radical hysterectomy was performed within 6 weeks after NAIAC. RESULTS Ninety-four patients were treated with NAIAC, and 49 patients undertook a PRH. The response rate of NAIAC on MRI was 92.6%. Fourteen patients (14.6%) had no evidence of cancer cells on pathologic diagnoses. The NAIAC group had a longer disease-free survival than the PRH group (p=0.02); however, the overall survival was not significantly different. The relative risk (RR) for recurrence was higher in patients with lymph node metastasis (RR, 4.31; 95% CI, 2.23-8.43) and lower in those who underwent NAIAC (RR, 0.30; 95% CI, 0.14-0.68). CONCLUSION Our results with NAIAC using the 4L-DB catheter in locally advanced cervical cancer indicates beneficial effects on primary lesions and improves disease-free survival.

Abstract
A 33-year-old woman, gravida two para one, at 31 weeks of gestational age experienced sudden onset of left lower quadrant pain and underwent unenhanced pelvic MRI. On fast imaging employing steady state precession (FIESTA) sequence images, a marked difference was observed in the diameters of the right and left ovarian veins. The right ovarian vein was torturous and dilated, measuring 35 mm in diameter, while the left ovarian vein was thin and linear, measuring 7 mm in diameter. The left ovary showed no apparent swelling or hemorrhage, but was suspected to have been shifted anteriorly. The patient underwent explorative laparotomy and was found to have left ovarian torsion. A difference in diameter of the ovarian veins, with thinning of the twisted side and compensatory dilatation of the contralateral side for drainage of increased uterine blood flow, may be a useful imaging sign for the diagnosis of ovarian torsion during pregnancy.

Abstract
Background Ovarian granulosa cell tumors (GCTs) are divided into adult GCT (AGCT) and juvenile GCT (JGCT). The AGCT is more common type, conversely, less than 5% of tumors are the JGCT and occur in mainly premenarchal girls and in women younger than 30 years. Although JGCT have different histologic features compared to AGCT, the two types have similar imaging features because they have similar gross appearance. Therefore, it is difficult to distinguish two types by radiologic findings. In addition, it has not been described about the growth rate of JGCTs in past literatures. The aims of this report were to describe a case of rapidly growing JGCT arising in adult with difficulty in diagnosing and to review the literatures. Case presentation A 38-year-old woman, presented with abdominal distension and frequent urination, was found to have a pelvic mass measuring approximately 12 cm on ultrasonography. On magnetic resonance imaging (MRI), right ovarian multiloculated cystic mass accompanied with hemorrhagic foci was demonstrated. Although the presumptive diagnosis of GCT was made based on MR findings, the intraoperative differential diagnoses included GCT, yolk sac tumor or malignant mucinous tumor due to cytologic atypia and lack of the typical findings for AGCT such as nuclear grooves and Call-Exner bodies. As a result, abdominal simple total hysterectomy, bilateral oophoro-salpingectomy, partial omentectomy and appendectomy were performed. Moreover, she had a history of laparoscopic uterine myomectomy about one year before, and during that surgery bilateral ovaries were found to be macrospically normal. Therefore, it was suspected the tumor became enlarged within the short period of time. Conclusions Even though it is difficult to distinguish two types of GCT by imaging findings, in some cases without typical findings for AGCT pathologically, MRI could provide useful information in accurately diagnosing JGCT. Moreover, in this case, the tumor growth rate seemed to be rapid regardless of its borderline malignant potential. It may be related with nuclear atypia and high mitotic rate of the tumor.

Abstract
Objective The histological tumor grade is a strong predictor of nodal metastasis in endometrial cancer; as such, an accurate pre- or intraoperative diagnosis is important for performing lymphadenectomy. Methods Ninety-one patients with endometrioid endometrial cancer were imaged on DW-MRI with the apparent diffusion coefficient (ADC) calculated and a frozen section (FS) diagnosis made before and at hysterectomy. The diagnostic accuracy for predicting the tumor grade for diffusion weighted magnetic resonance inaging (DW-MRI) and the FS diagnosis compared to the ultimate histologic status was analyzed. Results Among 91 patients with endometrioid endometrial cancer, high-grade (endometrioid G3) tumors had lower ADC values than low-grade (endometrioid G1/2) tumors. The cut-off of the mean ADCmean values for predicting high-grade tumors resulted in 743×10-6 mm2/sec according to the receiver operating characteristic curve. The true positive rates of ADC values and FSs for the prediction of high-grade tumors did not differ to a statistically significant extent (73.3% vs. 66.7%, p=0.7), however, the true negative rate of ADC values for the prediction of low-grade tumors was significantly lower than that of the FSs (64.5% vs. 98.7%, p=0.01). The kappa statistics of ADC values and FSs were 0.23 and 0.73, respectively. Of note, all five patients with high-grade tumors for whom intraoperative FSs indicated low-grade tumors were predicted to have high-grade tumors on preoperative DW-MRI. Conclusion A FS diagnosis is more suitable for predicting high-grade tumors than DW-MRI; however, physicians should pay close attention to tumors with low ADC values on preoperative DW-MRI.

Abstract
Matrix metalloproteinase-9 (MMP9) has been recognized to be an important factor in cancer invasion and metastasis. In contrast, decorin has been revealed to inhibit primary tumor development. The aim of the present study was to investigate the function of MMP9 and decorin in cervical cancer. Three experiments were performed to analyze the function of MMP9 and decorin in the invasion of cervical cancer by: i) Analyzing the expression of MMP9 and decorin by immunohistochemistry in 100 cervical specimens; ii) determining the concentration of decorin by an enzyme-linked immunosorbent assay (ELISA) using the human squamous cervical cancer cell line CaSki and human endometrial stromal cell line CRL4003 and iii) evaluating the invasion ability of CaSki cells in a cervical invasion model by an invasion assay. Immunohistochemistry revealed that MMP9 was overexpressed in microinvasive carcinoma (100.0%) but was less strongly expressed in normal or pre-malignant squamous epithelium (0-41.9%). In contrast, the activity of decorin in stroma adjacent to neoplastic cells was lower in microinvasive carcinoma (9.1%) compared with in normal or pre-malignant lesions (74.2-100.0%). An ELISA revealed that MMP9 released from CaSki cells resolved the decorin released from CRL4003 cells. An invasion assay demonstrated that the invasive ability of CaSki cells was suppressed by an MMP inhibitor, and decorin was released from CRL4003 cells. These data suggested that decorin prevented the invasion of malignant cells in uterine cervical cancer; however, MMP9 promotes cell invasion by destroying decorin.

Abstract
According to the sentinel node biopsy (SNB), systematic pelvic lymph node dissection (PLND) may not be needed for patients with early-stage endometrial cancer. On the other hand, imaging technology including fluorodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) has been developing worldwide. The aim of this study was to evaluate the combined diagnostic accuracy of FDG PET/CT and SNB in the prediction of pelvic lymph node metastasis in endometrial cancer patients.One hundred twenty-one patients with endometrial cancer underwent FDG PET/CT before hysterectomy and received SNB followed by systematic PLND. Univariate and multivariate analyses were performed to compare the diagnostic accuracy of FDG PET/CT and SNB in the prediction of pelvic node metastasis to the ultimate histologic status.FDG PET/CT had lower sensitivity (36.8% versus 57.9%, P = .1) and a higher specificity (96.4% versus 84.8%, P < .01) than SNB. The kappa statistics of FDG PET/CT and SNB were 0.37 (95% CI, 0.15-0.59) and 0.72 (95% CI, 0.53-0.90), respectively. The sensitivity of SNB was significantly higher than that of FDG PET/CT in all hemi-pelvises (HPs) in which the short axis of the largest metastatic lymph node was <5 mm in diameter (72.7% versus 18.2%, P = .01). In contrast, the sensitivity of FDG PET/CT was higher than that of SNB in all HPs in which the short axis of the largest metastatic lymph node was ≥5 mm in diameter (62.5% versus 37.5%, P = .2); however, the difference was not statistically significant. When the combined diagnosis of FDG PET/CT and SNB was made, the sensitivity and specificity were 84.2% and 82.1%, respectively.SNB was more useful for detecting lymph node metastasis than FDG PET/CT, especially in patients with small metastatic lymph nodes. The combined diagnosis of FDG PET/CT and SNB improves the sensitivity; PET-positive nodes should be dissected regardless of SNB status and HPs in which SNB was not detected should be dissected systematically regardless of FDG PET/CT status.

Abstract
Background It is well known that ovarian mature cystic teratomas (MCTs) occasionally go through malignant transformations. Among these, approximately 75% of histological types are squamous cell carcinoma, with the other types being exceptionally rare. We report an extremely rare case of ovarian clear cell carcinoma arising from ovarian mature cystic teratoma. Case presentation The case was a 71-year-old woman with abdominal distention. Ultrasonography and magnetic resonance imaging showed a huge mass in her abdominal cavity. Fluorodeoxyglucose-positron emission tomography (FDG-PET) showed FDG uptake not only in the pelvic tumor but also in the hepatic nodule, thus suggesting metastases. We performed a total abdominal hysterectomy, bilateral salpingo-oophorectomy, and an omentectomy. The pathological diagnosis showed clear cell carcinoma of the right ovary which arose from the MCT with malignant transformation pT2aNXM1. Although the patient underwent chemotherapy, she died after 17 months. Conclusion This case is histologically characteristic of the proof of transition from simple squamous epithelium via simple glandular epithelium to papillary change with atypia. This is the first case report of unaccompanied clear cell carcinoma arising from MCT reported in English literatures.

Abstract
In Japan, the trend for cervical cancer at younger ages has been increasing. As a countermeasure, the HPV vaccine was introduced as a routine vaccination in April 2013. However, the Ministry of Health, Labour and Welfare (MHLW) announced a “Suspension of its active inoculation recommendation for HPV vaccine” in June 2013. In 2016, 32 months after that suspension, we conducted survey via Internet and compared the results with our previous ones conducted at 9 and 23 months after suspension (in 2014 and 2015, respectively). We examined the ‘time-dependent change’ of the ‘intention of mothers to inoculate their daughters with the HPV vaccine’ in terms of efficacy of external decision-making support. 17.5% of mothers in the first survey replied that they would inoculate their daughters under the current circumstances, 12.1% in the second survey, and 6.7% in the third, showing a consistent decrease in willingness over time (p = 0.03, p < 0.01). If the government recommendation were to be reintroduced, 22.5% of mothers in the first survey replied they would inoculate their daughters, 21.0% in the second survey, which indicated no significant difference (p = 0.65) over the first interval; however, this was significantly decreased to 12.2% in the third survey (p < 0.01). Our study revealed that the intention to inoculate their daughters has been declining among Japanese mothers over time triggered by the suspension.

Abstract
Uterine leiomyoma is the most common benign tumour in women, and an appropriate animal model for leiomyoma would be useful for exploring new therapeutic strategies. Therefore, we have been challenged to develop a new simple mouse model for human leiomyoma. Leiomyoma tissues were harvested from myomas resected by different surgical procedures with or without gonadotropin-releasing hormone agonist (GnRHa) treatment and were subcutaneously implanted into BALB/c nude mice with an estradiol/progesterone-releasing pellet. The implanted leiomyoma tissues that were obtained from the marginal site of large myomas resected by abdominal myomectomy with GnRHa treatment exhibited sufficient tumour growth in the transplanted mice. The leiomyomas that were treated with GnRHa highly expressed the estrogen/progesterone receptor genes, insulin-like growth factor 2 (IGF2) and embryonic smooth muscle myosin heavy chain (SMemb), which suggests that these factors are critical in the establishment of a mouse model of growing leiomyoma. As a result, this model will be useful for the development of new therapeutic strategies.

Abstract
Objective Foretinib (GSK1363089 or XL880), which is an oral multikinase inhibitor developed to primarily target the hepatocyte growth factor (HGF)/Met signaling pathway, has shown anti-tumor effects against some cancers in preclinical and clinical studies. Results HGF/Met signaling in endometrial cancer cell lines was stimulated in an autocrine manner, and was essential for cell survival. Inhibiting the HGF/Met signaling with foretinib induced p53-dependent apoptosis in endometrial cancer cell lines in vitro. Foretinib also showed significant anti-cancer effects in vivo in experiments using cell tumor xenografts. p53 mutations were observed in 37 (10.8%) of 344 endometrial cancer specimens. Conclusion The HGF/Met-MAPK/PI3K pathway in endometrial cancer is activated by HGF in an autocrine manner. Foretinib induces an anti-cancer effect through the anti-phosphorylation of Met, which results in the induction of p53-dependent apoptosis; foretinib was found to exert greater anti-cancer activity in endometrial cancer specimens with wild-type p53 than in specimens with p53 mutations. Our immunochemical analysis revealed that foretinib-induced p53-dependent apoptosis can be expected to have therapeutic potential in approximately 90% of endometrial cancer patients. Methods We evaluated the HGF/Met signaling pathway in endometrial cancer cell lines and assessed the anti-cancer effects of foretinib using in vitro and in vivo experimental models. Furthermore, endometrial cancer specimens were subjected to an immunohistochemical analysis.

Abstract
AIM The aim of this study was to investigate whether FOXO1 and FOXO3 mRNA expression in granulosa cells is the cause of unexplained infertility. METHODS Thirty-one patients aged <40 years (13 with unexplained infertility and 18 with male partner infertility as a control group) whose serum anti-Müllerian hormone level was >0.5 ng/μL were enrolled in the study. All patients underwent oocyte retrieval under a short protocol from June 2012 to October 2013. Real-time PCR was carried out using mRNA extracted from granulosa cells retrieved from mature follicles. We compared FOXO1 and FOXO3 mRNA expression ratios in granulosa cells between the unexplained infertility group and the male infertility group. The relation between FOXO1 and FOXO3 mRNA expression ratios in granulosa cells and assisted reproduction technology clinical outcome was also examined. RESULTS FOXO3 mRNA expression ratio was significantly lower in the unexplained infertility group than in the male infertility group. Moreover, FOXO3 mRNA expression ratio showed a positive correlation with both the number of retrieved oocytes and serum anti-Müllerian hormone level. A positive correlation was also identified between FOXO1 mRNA expression and total dose of hMG. As well, the number of retrieved oocytes in the unexplained infertility group was statistically lower than that in the male infertility group. CONCLUSION A lower FOXO3 mRNA expression in granulosa cells leads to poor oocyte development in patients with unexplained infertility undergoing controlled ovarian stimulation for in vitro fertilization-embryo transfer.

Abstract
Systematic pelvic lymph node resection may not be needed for patients with cervical cancer, especially in the early stage, if the pre- or intraoperative diagnosis of lymph node status is correct. The aim of this study was to evaluate the diagnostic accuracy of pelvic lymph node metastasis for fluorodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) and sentinel node biopsy (SNB) of cervical cancer patients.Forty-eight patients with cervical cancer were imaged with FDG PET/CT before radical hysterectomy and underwent an SNB followed by systematic pelvic lymph node dissection. The diagnostic accuracy for predicting pelvic node metastases for FDG PET/CT and SNB compared with the ultimate histologic status was analyzed.Among 96 hemi-pelvises (HPs) in 48 patients, pelvic lymph node metastases were obtained in 12 HPs. The sensitivity of pelvic node metastases for FDG PET/CT and SNB was 8.3% and 75.0%, respectively. The specificity for FDG PET/CT and SNB was 97.6% and 94.0%, respectively. The negative predictive value for FDG-PET/CT and SNB was 88.2% and 100%, respectively.SNB is more suitable for detecting pelvic node metastases than FDG PET/CT. The omission of systematic pelvic lymphadenectomy should be considered based on the findings of SNB, not FDG PET/CT.

Abstract
INTRODUCTION Placental insufficiency is one of the major risk factors for growth restriction and preeclampsia. The aim of this study is to investigate whether recombinant human Thrombomodulin(r-TM) improves fetal conditions and physiological outcomes. METHODS We used CBA/J × BALB/C mice as a control and CBA/J × DBA/2 mice - a well-studied model of recurrent spontaneous miscarriage. Pregnant mice received daily subcutaneous injections of r-TM or saline from day 0-15. The fetal resorption rate, fetal weight, and litter size were calculated at day 15. Additionally, we analyzed the mRNA expression of angiogenic factors and the concentration of soluble Flt-1 (sFlt-1) using the ELISA kit. RESULTS The rate of fetal resorption in CBA/J × DBA/2 mice treated with r-TM was significantly lower compared with mice without r-TM treatment. Additionally, fetal weight and litter size were also significantly higher in the r-TM treated mice. Fibrinogen deposition in the labyrinth area of the CBA/J × DBA/2 mice treated with r-TM was significantly lower compared with deposits in the mice untreated with r-TM. As well, r-TM significantly increased the gene expression level of VEGF and Flt-1 mRNA in the placentas of the CBA/J × DBA/2 mice. r-TM treatment also significantly decreased the production of sFlt-1 protein in the placentas of preeclampsia-like diseased mice. CONCLUSION r-TM as an anticoagulation therapy has the potential for the medical treatment of recurrent miscarriage and fetal growth restriction due to improved angiogenic factors. Additionally, r-TM treatment has the potential for the recovery of preeclampsia.

Abstract
Background In Japan, the rate of cervical cancer screening is remarkably low, especially among women in their twenties and thirties, when cervical cancer is now increasing dramatically. The aim of this study was to test whether a modified government reminder for 20-year-old women to engage in cervical cancer screening, acting through maternal education and by asking for a maternal recommendation to the daughter to receive the screening, could increase their participation rate. Methods In two Japanese cities, 20-year-old girls who had not received their first cervical cancer screening before October of fiscal year 2014 were randomized into two study arms. One group of 1,274 received only a personalized daughter-directed reminder leaflet for cervical cancer screening. In the second group of 1,274, the daughters and their mothers received a combination package containing the same reminder leaflet as did the first group, plus an additional informational leaflet for the mother, which requested that the mother recommend that her daughter undergo cervical cancer screening. The subsequent post-reminder screening rates of these two study arms were compared. Results The cervical cancer screening rate of 20-year-old women whose mothers received the information leaflet was significantly higher than that for women who received only a leaflet for themselves (11% vs 9%, P = 0.0049). Conclusions An intervention with mothers, by sending them a cervical cancer information leaflet with a request that they recommend that their daughter receive cervical cancer screening, significantly improved their daughters’ screening rate.

Abstract
INTRODUCTION The aim of this study was to investigate the effect of laparoscopic endometriotic cystectomy and vaporization on ovarian reserve. METHODS We prospectively analyzed the serum level of anti-Mullerian hormone (AMH) in 62 patients at four different time points- preoperatively and at 1 month, 6 months, and 1 year postoperatively. Among the 62 cases, a bilateral cystectomy was performed in 10, bilateral vaporization in 16, a unilateral cystectomy in 24, and unilateral vaporization in 12. RESULTS The rate of AMH decline after unilateral cystectomy or bilateral cystectomy was higher than that after unilateral vaporization or bilateral vaporization. Age and bilaterality were associated with an AMH decline at 1 month, and age alone was associated with an AMH decline at 1 year. Moreover, being older than 38 years of age and having a revised American Society for Reproductive Medicine score >80 were independent risk factors for the non-recovery of AMH. CONCLUSION The rate of AMH decline after laparoscopic endometriotic vaporization is significantly lower than that after cystectomy. Both methods, however, have the potential to lower ovarian reserve, especially in cases of severe endometriosis or in patients older than 38 years of age.

Abstract
The aim of this study was to evaluate the dissemination of cancer cells at laparoscopic hysterectomy according to the intraperitoneal cytology.Patients with endometrial cancer underwent total laparoscopic modified radical hysterectomy. Peritoneal wash cytology was performed on entering the peritoneal cavity before surgical preparation and just after hysterectomy.Seventy-eight patients underwent laparoscopic hysterectomy for endometrial cancer. Among the 15 patients who had positive intraperitoneal cytology on entering the peritoneal cavity, 10 converted to negative intraperitoneal cytology after hysterectomy. In contrast, among the 63 patients who had negative intraperitoneal cytology on entering the peritoneal cavity, 2 converted to positive intraperitoneal cytology after hysterectomy.While surgery can reduce the number of cancer cells in the peritoneal cavity, leakage can occur, as seen in some cases of hysterectomy. Careful washing must be performed after hysterectomy.

Abstract
Objective: Laparoscopic surgery has been developed worldwide due to its minimal invasion as well as noninferiority, compared with laparotomy. However, whether or not laparoscopic systematic para-aortic lymphadenectomy for endometrial cancer is feasible and has advantages of various clinical factors, such as a short hospital stay, less blood loss, and faster recovery, compared with open surgery has not yet been clarified. The aim of this study was to compare a laparoscopic procedure with laparotomy for para-aortic lymphadenectomy for patients with endometrial cancer. Study Design: This was a retrospective multicenter study of laparoscopic systematic para-aortic lymphadenectomy for endometrial cancer in five institutions. Materials and Methods: The current authors conducted a retrospective multicenter study of laparoscopic systematic para-aortic lymphadenectomy for endometrial cancer. The study involved patients from five institutions in Japan between January 2008 and March 2016. Clinical data were compared with those of a laparotomic procedure performed around the same period. Results: A total of 54 patients in the laparoscopic group and 99 patients in the laparotomic group were analyzed. In the laparoscopic group, 21 patients had stage IA disease, 19 had stage IB disease, 5 had stage II disease, and 9 had stage III disease. In the laparotomic group, 35 patients had stage IA disease, 19 had stage IB disease, 9 had stage II disease, and 36 had stage III disease. There were no significant differences in characteristics between the groups, including age, body mass index, and histologic type. The mean operative time in the laparoscopic group was 483 ± 102 minutes, while that in the laparotomic group was 481 ± 106 minutes (p = 0.9). The laparoscopic group had less intraoperative blood loss (143 ± 253 versus 988 ± 694 mL; p < 0.01) and shorter hospital stays (8.4 ± 5.7 versus 16.1 ± 8.0 days; p < 0.01). The rates of intraoperative complications were not significantly different between the groups. No cases of ileus occurred in the laparoscopic group. Procedures for 2 of the 54 patients in the laparoscopic group were converted to laparotomy. The number of dissected pelvic lymph nodes (31.8 ± 10.1 versus 39.9 ± 15.9, p < 0.01) and para-aortic lymph nodes (26.2 ± 10.9 versus 31.1 ± 13.2; p = 0.02) were lower in the laparoscopic group than in the laparotomic group. The postoperative minimum level of hemoglobin was higher in the laparoscopic group than in the laparotomic group (10.4 ± 1.1 g/dL versus 9.9 ± 1.4 g/dL; p = 0.02). In contrast, the postoperative maximum level of C-reactive protein was lower in the laparoscopic group than in the laparotomic group (6.3 ± 3.8 mg/dL versus 10.2 ± 4.9 mg/dL; p < 0.01). The recurrence rate was not significantly different between the groups in the above time period (7.4% versus 14.3%; p = 0.2). Conclusions: Laparoscopic systematic para-aortic lymphadenectomy is feasible and can be substituted for laparotomic procedures for patients with early stage endometrial cancer.

Abstract
Background PD-0332991, the selective cyclin-dependent kinase 4/6 inhibitor palbociclib, causes cell cycle arrest by inhibiting phosphorylation of retinoblastoma (Rb) protein. The aim of this study was to evaluate the therapeutic potential of PD-0332991 in endometrial cancer. Methods and findings Four human endometrial cancer cell lines, ECC, HEC1A, HEC108 and TEN, were treated with PD-0332991 and their function was evaluated. In vivo, the therapeutic efficacy was evaluated in a model of subcutaneous endometrial cancer. An immunohistochemical analysis was performed in 337 endometrial cancer specimens. A proliferation assay revealed that 2 of the 4 cell lines that expressed Rb were sensitive to PD-0332991 with an IC50 of 0.65 μM (HEC1A) and 0.58 μM (HEC108), respectively. Both cell lines had G0/G1 cell cycle arrest after treatment with PD-0332991 according to flow cytometry. In vivo, PD-0332991 had antitumoral efficacy with a reduction in the activity of Ki67 and phosphorylation of Rb. Immunohistochemical analyses revealed that the positive rate of Rb was 67.7%, however, there was no significant relationship between the expression levels of Rb and the tumor grade. Conclusions PD-0332991 had therapeutic potential against endometrial cancer cell lines expressing Rb protein. Our immunohistochemical analysis revealed that approximately 70% of patients with endometrial cancer might have therapeutic indications for PD-0332991. Of note, the tumor grade had no impact on the indications for treatment.

Abstract
The degree of peritoneal dissemination and chemotherapy-resistant tumors is related to the prognosis in patients with advanced-stage ovarian cancer. The epithelial-mesenchymal-transition (EMT) is a multifaceted pathological program that endows cancer cells with the ability to invade and disseminate. CD24 is frequently overexpressed in various human cancers and is correlated with a poor prognosis. We herein examined the functions of CD24 in human ovarian cancer cell lines and evaluated how it contributes to the molecular mechanism underlying the regeneration of cancer stem-like cells (CSCs) through the EMT mechanism in ovarian carcinoma. We demonstrated that CD24 was expressed in 70.1% of primary ovarian carcinoma tissues, which were obtained from 174 patients, and that the expression of CD24 was an independent predictor of survival in patients with ovarian cancer. The expression of CD24 has been found to be correlated with the FIGO stage, presence of peritoneal and lymph node metastasis. CD24 induces the EMT phenomenon, which is involved in cell invasion, the highly proliferative phenotype, colony formation and which is associated with cisplatin resistance and the properties of CSCs, via the activation of PI3K/Akt, NF-κB and ERK in Caov-3 cisplatin-resistant cell lines. CD24-positive ovarian carcinomas have been shown to have a greater potential for intra-abdominal tumor cell dissemination in in vivo models. Our findings suggest that CD24 induced the EMT phenomenon in ovarian cancer, and that CD24 amplified cell growth-related intracellular signaling via the PI3K/Akt and MAPK pathways by affecting the EMT signal pathways. We believe that CD24 is a key molecule of metastatic progression in the EMT phenomenon and a promising therapeutic target for advanced ovarian cancer.

Abstract
Objective: In Japan, the possible adverse events upon HPV vaccination was widely reported in the media. MHLW announced the suspension of aggressively encouraging HPV vaccination in 2013, and inoculation rate has sharply declined. The aim of the present study was estimation of future cervical cancer risk. Methods: The latest data on vaccination rate at each age in Sakai City were first investigated. The rate of experiencing sexual intercourse at the age of 12, 13, 14, 15, 16, 17 and throughout lifetime is assumed to be 0%, 1%, 2%, 5%, 15%, 25%, and 85% respectively. The cervical cancer risk was regarded to be proportional to the relative risk of HPV infection over the lifetime. The risk in those born in 1993 whom HPV vaccination was not available yet for was defined to be 1.0000. Results: The cumulative vaccination rates were 65.8% in those born in 1994, 72.7% in 1995, 72.8% in 1996, 75.7% in 1997, 75.0% in 1998, 66.8% in 1999, 4.1% in 2000, 1.5% in 2001, 0.1% in 2002, and 0.1% in 2003. The relative cervical cancer risk in those born in 1994–1999 was reduced to 0.56–0.70, however, the rate in those born in 2000–2003 was 0.98–1.0, almost the same risk as before introduction of the vaccine. Discussion: The cumulative initial vaccination rates were different by the year of birth. It is confirmed that the risk of future cervical cancer differs in accordance with the year of birth. For these females, cervical cancer screening should be recommended more strongly.

Abstract
Aim To investigate which risk factors contribute to a lower oocyte retrieval ratio in women who are receiving controlled ovarian hyperstimulation. Methods The authors retrospectively analyzed 329 in vitro fertilization (IVF) cycles under controlled ovarian hyperstimulation by using a gonadotropin‐releasing hormone antagonist or agonist at Osaka Medical College, Japan. The patients were classified into five groups: advanced age, male infertility, severe endometriosis, tubal infertility, and unexplained infertility. The primary outcomes were the patients’ age, oocyte retrieval ratio, serum basal follicle‐stimulating hormone, total dose of gonadotropin, and the clinical outcome. A secondary outcome was the stepwise multivariate logistic regression analysis to assess the factors associated with the failure of oocyte retrieval. Results The oocyte retrieval ratio declined significantly with the patient's age. The ratio of endometriosis in unsuccessful cases was significantly higher than that in successful cycles. Advanced age and endometriosis were the factors that were significantly associated with a lowered oocyte retrieval rate. Conclusion Advanced age and endometriosis are high‐risk factors that contribute to oocyte retrieval failure in infertile patients who are receiving IVF treatment.

Abstract
OBJECTIVE Our objective was to determine the feasibility and detection rates and clarify the most effective combination of injected tracer types for sentinel lymph node (SLN) mapping in uterine cervical cancer in patients who have undergone laparoscopic surgery or neoadjuvant chemotherapy (NAC). METHODS A total of 119 patients with cervical cancer underwent SLN biopsy at radical hysterectomy using three types of tracers. The various factors related to side-specific detection rate, sensitivity, and false negative (FN) rate were analyzed. RESULTS The SLN detection rates using 99m-technetium ((99m)Tc)-tin colloid, indigo carmine, and indocyanine green (ICG) were 85.8%, 20.2%, and 61.6%, respectively. The patients with ≥2-cm-diameter tumors and those who received NAC had lower detection rates than those with <2-cm-diameter tumors (75.7% vs. 91.5%, p<0.01) and those who did not receive NAC (67.9% vs. 86.3%, p<0.01), respectively. Laparoscopic procedures had a higher detection rate than laparotomy (100.0% vs. 77.1%, p<0.01). No factors significantly affected the sensitivity; however, the patients with ≥2-cm-diameter tumors (86.0% vs. 1.4%, p<0.01), NAC (19.4% vs. 2.2%, p<0.01), and those who underwent laparotomy (7.4% vs. 0%, p<0.01) had an unfavorable FN rate. CONCLUSION Among the examined tracers, (99m)Tc had the highest detection of SLN mapping in patients with uterine cervical cancer. Patients with local advanced cervical cancer with/without NAC treatment might be unsuited for SLN mapping. SLN mapping is feasible and results in an excellent detection rate in patients with <2-cm-diameter cervical cancer. Laparoscopic surgery is the best procedure for SLN detection in patients with early-stage disease.

Abstract
Background In Japan, new HPV immunizations have dropped dramatically after repeated adverse media reports and a June 2013 temporary suspension of the government’s recommendation for the vaccine. The aim of the present study was to develop an efficient strategy to improve HPV immunization coverage across Japan. Methods We conducted an internet survey in Japan of mothers of 12–16 year-old girls who were unvaccinated as of May, 2015. The goal was to gather behavioral information from the mothers to develop a strategy for improving Japanese HPV immunization coverage. Results Valid survey answers were obtained from 2060 mothers. The survey found that a hypothetical restart of a governmental recommendation for the vaccine would induce 4.1 % of all the mothers surveyed to be more likely to encourage vaccination of their daughters, without any other preconditions. This initial result would be followed by a moderate spread of vaccinations to these daughters’ close friends and acquaintances, hypothetically resulting in a total vaccination rate of 21.0 % of the targeted age-eligible girls. As a second critical step for improving vaccinations, an educational information sheet integrating the concepts of behavioral economics for changing behaviors was found to be significantly effective for persuading mothers with poorer decision-making facilities, who would otherwise prefer to wait to first see the vaccination of other girls of the same age as their daughter. Conclusions Following what we foresee as the inevitable restart of the Japanese government’s recommendation for receiving the HPV vaccine, we expect to first see vaccinations occurring in a very small group of girls, the daughters of the most willing mothers, which will be roughly 4 % of those eligible for government paid vaccinations. This will be followed by the spread of vaccinations outward through these girls’ circle of friends and acquaintances, and, finally, to the daughters of the most skeptical mothers, those who would await the return of new vaccine safety results from a large group of similarly-aged girls. As a critical step in improving HPV vaccine coverage in Japan, an educational information sheet that integrates the concepts of behavioral economics for changing behaviors can be employed to persuade mothers with poor decision-making facilities.
