RESUMO
OBJECTIVE: This study aimed to investigate the prognostic significance of tumor size and number of positive pelvic lymph nodes (PLN) in International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IIIC1 cervical cancer patients. METHODS: Clinical data from 626 women with cervical cancer treated at Osaka International Cancer Center in 2010-2020 were retrospectively reviewed. Using the cutoff value obtained on the receiver operating characteristic analysis, the prognostic significance of tumor size and number of positive PLN in stage IIIC1 patients was first evaluated via uni- and multivariate analyses. Then, the impact of incorporating tumor size and number of positive PLN into the FIGO staging system was investigated using the Kaplan-Meier method. RESULTS: Among 196 women with Stage IIIC1 disease, larger tumors (>4 cm) and multiple PLN metastases (≥4) were independent predictors of progression-free survival (PFS) in patients with stage IIIC1 cervical cancer. The PFS of patients with stage IIIC1 disease was inversely associated with the number of risk factors. Although patients with stage IIIC1 disease had significantly increased survival rates compared to those with stage IIIA or IIIB disease in the original FIGO 2018 staging system, this reversal phenomenon was resolved by incorporating larger tumors (>4 cm) and multiple PLN metastases (≥4) into the revised staging system. CONCLUSIONS: Incorporating tumor size and number of metastatic lymph nodes into the FIGO staging system allows additional risk stratification for women with stage IIIC1 cervical cancer and improves survival prediction performance.

PURPOSE: The goal of this study was to evaluate, using definitive diagnostic criteria, the incidence of lymphocyst formation following pelvic lymphadenectomy for gynecological cancer, and to compare rates between the approaches of laparoscopy and laparotomy. METHODS: We retrospectively reviewed the medical records of all patients who underwent pelvic lymphadenectomy for cervical or endometrial cancer between March of 2010 and March of 2016. We defined a lymphocyst as a circumscribed collection of fluid within the pelvic cavity, with a diameter of 2 cm or more, as diagnosed with ultrasound or computed tomography. RESULTS: During the six-year observational period, a pelvic lymphadenectomy was conducted in 196 women with clinical stage I uterine cancer; 90 cases underwent laparoscopy, 106 underwent laparotomy. The minimally invasive laparoscopic group had a lower estimated blood loss (p < 0.01), shorter hospital stay (p < 0.01). Lymphocysts were observed in 14.4% (13/90) of the laparoscopy cases, and in 15.1% (16/106) of the laparotomy cases which means no significant difference of lymphocyst (p = 1.00). The median size of symptomatic lymphocyst was significantly larger in laparotomy group than in laparoscopy group (4.8 cm v.s. 2.8 cm, median) (p = 0.04). Symptomatic lymphocysts were more common in laparotomy [7/90 (7.8%) vs 14/106 (13.2%) (p = 0.253)]. CONCLUSIONS: In a retrospective analysis with a strict diagnostic criteria, we could find no statistical difference in lymphocyst occurrence between laparoscopy and laparotomy. The median size of the lymphocyst was bigger and lymphocyst was likely to be symptomatic in the laparotomy group.

BACKGROUND: Smartphones recently have been applied in the medical setting. However, the literature evaluating the utility of smartphones in gynecologic oncology is limited. OBJECTIVE: To evaluate the utility of a smartphone in the detection of uterine cervical lesions in patients with abnormal cervical cytology. STUDY DESIGN: Seventy-five women with abnormal cervical cytology were enrolled. Two doctors independently inspected the uterine cervix by using smartphone or colposcopy. Images were captured using acetic acid, and biopsies were taken as standard-of-care procedures. The diagnostic performance of the smartphone for cervical intraepithelial neoplasm 1 or worse and cervical intraepithelial neoplasm 2 or worse were evaluated, and the kappa value was calculated to determine the chance corrected agreement of the histologic diagnoses based on the smartphone and colposcopic findings. RESULTS: There was a substantial agreement between histologic diagnoses based on the smartphone and colposcopic findings, with a kappa value of 0.67 (95% confidence interval, 0.43-0.90). The sensitivity, specificity, positive predictive value, and negative predictive value of the smartphone in the diagnosis of cervical intraepithelial neoplasm 1 or worse were 0.89 (95% confidence interval, 0.79-0.96), 0.33 (95% confidence interval, 0.08-0.70), 0.91 (95% confidence interval, 0.81-0.97), and 0.30 (95% confidence interval, 0.07-0.65), respectively. The sensitivity, specificity, positive predictive value, and negative predictive value in the diagnosis of cervical intraepithelial neoplasm 2 or worse were 0.92 (95% confidence interval, 0.81-0.98), 0.24 (95% confidence interval, 0.09-0.45), 0.71 (95% confidence interval, 0.58-0.81), and 0.60 (95% confidence interval, 0.26-0.88), respectively. CONCLUSION: We found that there was a substantial agreement between the histologic diagnoses based on the smartphone and colposcopic findings. The smartphone seems to be useful and may be an alternative to colposcopy.

BACKGROUND: In Japan, the cervical cancer preventative HPV vaccination rate has dramatically declined, directly as a result of repeated broadcasts of so-called adverse events and the resulting suspension of the government's recommendation. Our previous survey of obstetricians and gynecologists in Japan regarding their opinions toward HPV vaccination revealed that these key specialists were as negatively influenced by the reports of purported negative events as were the general population. Here, we report a 3-year follow-up survey of these clinicians. METHODS: We reused the same questionnaire format as used in our 2014 survey, but added new questions concerning opinions regarding a WHO statement and reports of a Japanese nation-wide epidemiological study related to the adverse events, released in 2015 and 2016, respectively. RESULTS: The response rate was 46% (259/567): 5 (16.1%) of 31 doctors had inoculated their own teenaged daughters during the time period since the previous survey, despite the continued suspension of the governmental recommendation, whereas in the previous survey none of the doctors had done so. Among the respondents, the majority claimed awareness of the recent pro-vaccine WHO statement (66.5%), and of the report of a Japanese epidemiological study (71.5%), and a majority affirmed they currently held positive opinions of the safety (72.7%) and effectiveness (84.3%) of the HPV vaccine. CONCLUSIONS: Our re-survey of Japan's obstetricians and gynecologists regarding their opinions about the HPV vaccine found that their opinions have changed, potentially leading to a more positive future re-engagement for HPV vaccination in Japan.

PURPOSE: To assess and compare maternal and neonatal outcomes of pregnancy with or without mental disorders. METHODS: We performed a retrospective cohort study of births at our institution from January 2009 to December 2011, which included all live singleton births during these 3 years. Women emergently transferred to our institution in the middle of their pregnancies were excluded. Associations between mental disorders and perinatal outcomes were estimated using statistical analysis, and multivariable analysis was performed using propensity score-based weighting. RESULTS: A total of 1,166 women were included, 152 (13.0 %) of whom had mental disorders. Comparison of maternal characteristics showed that women with mental disorders were significantly more likely to be multiparous, smokers, recipients of public assistance, unmarried, and to have inadequate perinatal care. Comparison of perinatal outcomes showed that preterm births (PTB) before 37 weeks were significantly increased in women with mental disorders (10.5 vs. 6.0 %, P = 0.037). There were no significant differences in low birth weight (LBW), pregnancy-induced hypertension, and gestational diabetes mellitus. Multivariable analysis using propensity score weighting showed that after adjusting for other factors, women with mental disorders were more likely than women without mental disorders to have PTB before 34 weeks [adjusted odds ratio (OR) 4.79, 95 % confidence interval (CI) 1.49-15.4; P = 0.009], PTB before 37 weeks (adjusted OR 2.46, 95 % CI 1.62-3.69; P < 0.001), or LBW (adjusted OR 1.83; 95 % CI 1.32-2.55; P < 0.001). CONCLUSION: Maternal mental disorders were associated with adverse birth outcomes and socioeconomic disadvantage.

The placenta has several crucial physiological functions that help maintain a normal pregnancy. Although approximately 2-4% of pregnancies are complicated by abnormal placentas, obstetric outcomes remain understudied. This study aimed to determine the outcomes and prevalence of patients with abnormal placentas by conducting a systematic review of 48 studies published between 1974 and 2022. The cumulative prevalence of circumvallate placenta, succenturiate placenta, multilobed placenta, and placenta membranacea were 1.2%, 1.0%, 0.2%, and 0.004%, respectively. Pregnancies with a circumvallate placenta were associated with an increased rate of emergent cesarean delivery, preterm birth (PTB), and placental abruption compared to those without a circumvallate placenta. The succenturiate lobe of the placenta was associated with a higher rate of emergent cesarean delivery, whereas comparative results were observed in terms of PTB, placental abruption, and placenta previa in comparison to those without a succenturiate lobe of the placenta. A comparator study that examined the outcomes of multilobed placentas found that this data is usually unavailable. Patient-level analysis (n = 15) showed high-rates of abortion (40%), placenta accreta spectrum (40%), and a low term delivery rate (13.3%) in women with placenta membranacea. Although the current evidence is insufficient to draw a robust conclusion, abnormal placentas should be recognized as a high-risk factor for adverse outcomes during pregnancy.
RESUMO
Randomized clinical trials assessing the efficacy of neoadjuvant chemotherapy (NACT) for advanced epithelial ovarian cancer have predominantly included women with high-grade serous carcinomas. The response rate and oncological outcomes of NACT for malignant ovarian germ cell tumors (MOGCT) are poorly understood. This study aimed to examine the effects of NACT on women with MOGCT by conducting a systematic review of four public search engines. Fifteen studies were identified, and a further descriptive analysis was performed for 10 original articles. In those studies, most women were treated with a bleomycin, etoposide, and cisplatin regimen, and one to three cycles were used in most studies. Four studies comparing NACT and primary debulking surgery showed similar complete response rates (n = 2; pooled odds ratio [OR] 0.90, 95% confidence interval [CI] 0.15-5.27), comparable overall survival (n = 3; 87.0-100% versus 70.0-100%), disease-free survival (n = 3; 87.0-100% versus 70.0-100%), recurrence rate (n = 1; OR 3.50, 95%CI 0.38-32.50), and adverse events rate from chemotherapy between the groups. In conclusion, NACT may be considered for the management of MOGCT; however, possible candidates for NACT use and an ideal number of NACT cycles remain unknown. Further studies are warranted to validate the efficacy of NACT in advanced MOGCT patients.
RESUMO
In early-stage cervical cancer, ovarian metastasis is relatively rare, and ovarian transposition is often performed during surgery. Although rare, the diagnosis and surgical approach for recurrence at transposed ovaries are challenging. This study focused on the diagnosis and surgical management of transposed ovarian recurrence in cervical cancer patients. A 45-year-old premenopausal woman underwent radical hysterectomy, bilateral salpingectomy, and pelvic lymphadenectomy following postoperative concurrent chemoradiotherapy for stage IB1 cervical cancer. During the initial surgery, the ovary was transposed to the paracolic gutter, and no postoperative complications were observed. Ovarian recurrence was diagnosed using positron emission tomography-computed tomography, and a laparoscopic bilateral oophorectomy was performed. A systematic review identified nine women with transposed ovarian recurrence with no other metastases of cervical cancer, and no studies have discussed the optimal surveillance of transposed ovaries. Of those (n = 9), four women had died of the disease within 2 years of the second surgery, and the prognosis of transposed ovarian cervical cancer seemed poor. Nevertheless, three women underwent laparoscopic oophorectomies, none of whom experienced recurrence after the second surgery. Few studies have examined the surgical management of transposed ovarian recurrence. The optimal surgical approach for transposed ovarian recurrence of cervical cancer requires further investigation.

Vasa previa is a rare fetal life-threatening obstetric disease classified into types I and II. This study aimed to examine the characteristics and obstetric outcomes of type II vasa previa. A systematic review was performed, and 20 studies (1998-2022) were identified. The results from six studies showed that type II vasa previa accounted for 21.3% of vasa previa cases. The characteristics and obstetric outcomes (rate of assisted reproductive technology (ART), antenatal diagnosis, emergent cesarean delivery, maternal transfusion, gestational age at delivery, and neonatal mortality) were compared between type I and II vasa previa, and all outcomes of interest were similar. The association between ART and abnormal placenta (bilobed placenta or succenturiate lobe) was examined in three studies, and the results were as follows: (i) increased rate of succenturiate lobes (ART versus non-ART pregnancy; OR (odds ratio) 6.97, 95% confidence interval (CI) 2.45-19.78); (ii) similar rate of abnormal placenta (cleavage-stage versus blastocyst embryo transfer); (iii) increased rate of abnormal placenta (frozen versus fresh embryo transfer; OR 2.97, 95%CI 1.10-7.96). Although the outcomes of type II vasa previa appear to be similar to those of type I vasa previa, the current evidence is insufficient for a robust conclusion.
RESUMO
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.

Ovarian cancer is the leading cause of gynecologic cancer-related deaths and novel therapeutic strategies are required. Programmed cell death 1 and programmed cell death ligand 1 (PD-L1), which are key mediators of host immune tolerance, are associated with ovarian cancer progression. Recent evidence indicates the importance of IFNγ-induced PD-L1 for immune tolerance in ovarian cancer. This study aimed to reveal the therapeutic potential of suppressor of cytokine signaling 1 (SOCS-1), an endogenous inhibitor of the Janus kinase (JAK)-STAT signaling pathway, for the treatment of ovarian cancer. IHC assessment revealed that patients with ovarian cancer with high intratumoral STAT1 activation exhibited poor prognosis compared with patients with low STAT1 activation (P < 0.05). Stimulation of OVISE, OVTOKO, OV2944-HM-1 (HM-1), and CT26 cell lines with IFNγ induced STAT1 phosphorylation and PD-L1 expression. Adenovirus-mediated SOCS-1 gene delivery (AdSOCS-1) in HM-1 and CT26 cells in vitro potently inhibited IFNγ-induced STAT1 phosphorylation and PD-L1 upregulation, similar to the addition of JAK inhibitor I, but failed to inhibit their proliferation. Notably, intratumoral injection of AdSOCS-1, but not AdLacZ, significantly inhibited the tumor growth of HM-1 and CT26 cells subcutaneously transplanted in immunocompetent syngeneic mice. AdSOCS-1 reduced PD-L1 expression on tumors and restored the activation of tumor-infiltrating CD8+ T cells. Moreover, the antitumor effect of AdSOCS-1 was significantly attenuated by PD-L1 Fc-fusion protein administration in vivo, suggesting that the effect of AdSOCS-1 is mainly attributable to enhancement of tumor immunity. This study highlights the potential clinical utility of SOCS-1 as an immune checkpoint inhibitor. Mol Cancer Ther; 17(9); 1941-50. ©2018 AACR.

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.

OBJECTIVE: The aim of this study was to determine the predictive value of high-normal blood pressure (HNBP) during the early second trimester for hypertensive disorders in pregnancy, including gestational hypertension (GH) and preeclampsia (PE). METHODS: This was a retrospective single-center cohort study of 2143 singleton pregnant women. The association of HNBP, ranging from 130/85 to 139/89 mmHg between 14 and 19 weeks of gestation, with the development of hypertensive disorders was assessed by multivariable logistic regression analyses. RESULTS: In a cohort of 2102 pregnant women, 93 (4.4%) pregnancies had HNBP during early second trimester. Pregnant women with HNBP more frequently developed hypertensive disorders than normotensive women (20.4% vs. 8.2%, p < 0.001). HNBP was significantly associated with the development of GH (adjusted odds ratio (aOR): 1.81; 95% confidence interval (CI): 1.16-3.25, p = 0.015) and PE (aOR: 6.05; 95% CI: 3.46-12.6, p = 0.013) after adjustment for confounders. CONCLUSION: HNBP during the early second trimester is an independent risk factor for both GH and PE.

OBJECTIVE: Hypertensive disorders in pregnancy are major causes of maternal mortality and morbidity. Although the combined risk assessments of maternal history, blood pressure, uterine artery Doppler, and maternal serum marker seem to be highly predictive of the development of hypertensive disorders, this method is a little complicated to be performed on many low-risk pregnant women. The aim of this study is to evaluate the use of maternal characteristics, and physical findings early in the second trimester, as predictive factors of hypertensive disorders. MATERIALS AND METHODS: This is a retrospective cohort study undertaken in a single tertiary care center in Japan. Singleton pregnant women without underlying disease and evaluated before 14 weeks of gestation were included. We conducted multivariate logistic regression analysis and decision tree analysis to elucidate the potential risk factors of hypertensive disorders, including gestational hypertension and preeclampsia. RESULTS: In total, 1986 women were evaluated, of whom 863 were nulliparous and 1123 were multiparous, and 166 (8.3%) were diagnosed with hypertensive disorders. In multivariate analysis, maternal age ≥ 40 years, prepregnancy BMI ≥ 30 kg/m(2), in vitro fertilization and embryo transfer (IVF-ET), family history of hypertension, and blood pressure ≥ 130/85 mmHg at first visit were independent risk factors for the nulliparous women. Maternal age ≥ 40 years, a history of previous hypertensive disorders, and blood pressure ≥ 130/85 mmHg at first visit were independent risk factors for the multiparous women. According to the decision tree analysis, high-risk populations were as follows: women ≥ 40 years old who conceived thorough IVF-ET and women with prepregnancy BMI ≥ 30 kg/m(2) who conceived spontaneously in nulliparous women; women with a history of hypertensive disorders and women with blood pressure ≥ 130/85 mmHg in the absence of the previous history. CONCLUSION: The combination of maternal background and physical findings is useful to identify the population with a high risk of hypertensive disorders.

OBJECTIVE: To identify the clinical features and risk factors for diagnosis of a postpartum-onset hypertensive disorder. METHODS: A retrospective cohort study of singleton pregnancies. Clinical features of postpartum-onset hypertensive disorders were evaluated, and prenatal risk factors were also identified with a multivariate logistic regression model. RESULTS: Of 1,964 women, 57 (2.9%) developed hypertensive disorder after delivery. The independent risk factors were assisted reproductive technology, pre-pregnancy body mass index, chronic nephritis, hypothyroidism, high-normal blood pressure before or at delivery, and cesarean section. CONCLUSION: Careful monitoring of blood pressure should be considered for women with the identified risk factors even after delivery.
