RESUMO
In November 2021, the government of Japan announced a reversal of its decision in 2013 to suspend the previous proactive recommendation for HPV vaccination. However, the program for young girls to receive routine and catch-up vaccinations has not necessarily developed as expected. We conducted a nationwide questionnaire survey by mail in September 2022. The survey was mailed to 133 municipalities consisting of all cities/wards of the Tokyo and Osaka Prefectures and all other prefectural capital cities. Responses were received from 82 municipalities (62.7%). Notification of routine HPV vaccinations had already been sent to 76 (92.7%) of the municipalities; 70 (85.4%) had been encouraged to promote catch-up vaccinations. The questionnaire forms for registration and pre-vaccination screening for routine immunization had been sent to 74.1% (60/81) of the municipalities and 68.8% (55/80) for catch-up immunizations. For catch-up vaccination, only 54 municipalities (65.9%) had detailed vaccination records for those eligible. In total, 10 municipalities (12.2%) had virtually no vaccination records because these had already been discarded. In addition, 61 municipalities (74.4%) had notified only women and girls eligible for a catch-up vaccination based on their vaccination record, whereas 25.6% (21/82) of the municipalities reported that they had sent, or would send, the notification to all women and girls within the targeted grades, including those who had already been vaccinated with three injections. The survey revealed disparities among the municipalities in their HPV vaccine notification processes. Future research on monitoring HPV vaccination rates and incidence rates of cervical cancer and precancerous lesions in each municipality will be desirable.

PURPOSE: In Japan, Japan's Ministry of Health, Labor, and Welfare decided to suspend govermental recommendation for HPV vaccination in FY 2013. The HPV vaccination rate for those born in FY 2000 or thereafter declined dramatically. In 2021, the "suspension of recommendation" ended. The catch-up vaccinations for the unvaccinated have been offered nationwide from FY 2022 to FY 2024. We aimed to quantify the vaccination intentions and characteristics of those young women now eligible for catch-up vaccination. METHODS: In February of 2022, we conducted an internet survey targeted women who were born in 1997-2004 but who had not yet been HPV vaccinated. RESULTS: We received 1,648 valid responses. 41.6% of the respondents wanted to uptake the catch-up HPV vaccination, 29.7% were undecided, and 28.7% did not want to be vaccinated. The intention to uptake catch-up HPV vaccination was associated with a good history of gynecological visits, intention to receive cervical cancer screening, sexual activity, degree of anxiety about cervical cancer, familiarity with problems associated with cervical cancer, experience with vaccination recommendations, and knowledge about cervical cancer (p < 0.05, respectively). In the vaccinated generation, the proportion of the group that did not want to be vaccinated was significantly higher (p < 0.05). In the vaccine-suspended generation, the proportion of the group that wanted to be vaccinated was significantly higher (p < 0.05). CONCLUSION: Our survey revealed that catch-up vaccination intentions differed depending on the vaccination environment. It is necessary for all organizations involved with HPV vaccination, such as government, medical institutions, and educational institutions, to make recommendations based on an understanding of the characteristics of the "vaccinated generation" and the "vaccine-suspended generation".

BACKGROUND: This study assesses the feasibility of minimally invasive surgery (MIS) for well-selected epithelial ovarian cancer (EOC) patients. METHODS: We performed a review of data prospectively collected from a single center from 2017 to 2022. Only patients with histologically confirmed EOC, with a tumor diameter of less than 10 cm, were eligible. We also performed a meta-analysis of similar studies comparing the outcomes of laparoscopy and laparotomy. We used MINORS (Methodological Index for Non-Randomized Studies) to assess the risk of bias and calculated the odds ratio or mean difference. RESULTS: Eighteen patients were included; 13 in re-staging group, four in PDS group, and one in IDS group. All achieved complete cytoreduction. One case was converted to laparotomy. The median number of removed pelvic lymph nodes was 25 (range 16-34), and 32 (range 19-44) for para-aortic nodes. There were two (15.4%) intraoperative urinary tract injuries. The median follow-up was 35 months (range 1-53). Recurrence was observed in one case (7.7%). Thirteen articles for early-stage ovarian cancer were included in our meta-analysis. Analysis of the pooled results found that MIS had a higher frequency of spillage (OR, 2.15; 95% CI 1.27-3.64). No differences were observed in recurrence, complications, or up-staging. CONCLUSIONS: Our experience supports the possibility of conducting MIS for EOC in well-selected patients. Except for spillage, our meta-analysis findings are consistent with previous reports, the majority of which were also retrospective. Ultimately, randomized clinical trials will be needed to authenticate the safety.

The incidence of uterine corpus cancer has been increasing globally due to increase in obesity. However, a detailed analysis of long-term epidemiological trends of corpus cancer in Japan, where obesity is relatively minimal, has not been conducted. In this retrospective, population-based study using the Osaka Cancer Registry, we analyzed 15 255 cases of corpus neoplasia registered between 1977 and 2016. We determined the age-standardized incidence, mortality, relative survival and conditional survival rates, and the treatment trends for corpus cancer over the last 40 years in Japan. The age-standardized incidence rate of corpus neoplasia increased sharply in 2000-2011 (APC = 9.9, 95% CI: 8.4-11.3), whereas the mortality rate trended to a much more modest increase (APC = 3.3, 95% CI: 2.7-3.8). Compared to 1977-2000, 10-year survival rates for post-2000 cases of localized and regional corpus cancers significantly improved (from 87.7% [95% CI: 85.8-89.4] to 94.2% [95% CI: 92.7-95.7] and from 47.5% [95% CI: 43.3-51.6] to 64.4% [95% CI: 61.0-67.6], respectively). This was largely associated with the significant increase in the percentage of localized and regional patients who received chemotherapy instead of radiation as an adjuvant therapy combined to surgery (P < .001 for both). We found that each histological type (endometrioid carcinoma, serous carcinoma, clear cell carcinoma and carcinosarcoma) has different characteristics of trend of age-standardized incidence rate, relative survival and distribution of extent of disease. In endometrioid carcinoma, the age-standardized incidence rate increased consistently after 1990, but the rate of increase was decreasing after 1997.

BACKGROUND: Endometrial cancer (EC) is a common gynecologic malignancy and patients with advanced and recurrent EC have a poor prognosis. Although chemotherapy is administered for those patients, the efficacy of current chemotherapy is limited. Therefore, it is necessary to develop novel therapeutic agents for EC. In this study, we focused on lipolysis-stimulated lipoprotein receptor (LSR), a membrane protein highly expressed in EC cells, and developed a chimeric chicken-mouse anti-LSR monoclonal antibody (mAb). This study investigated the antitumor effect of an anti-LSR mAb and the function of LSR in EC. METHODS: We examined the expression of LSR in 228 patients with EC using immunohistochemistry and divided them into two groups: high-LSR (n = 153) and low-LSR groups (n = 75). We developed a novel anti-LSR mAb and assessed its antitumor activity in an EC cell xenograft mouse model. Pathway enrichment analysis was performed using protein expression data of EC samples. LSR-knockdown EC cell lines (HEC1 and HEC116) were generated by transfected with small interfering RNA and used for assays in vitro. RESULTS: High expression of LSR was associated with poor overall survival (hazard ratio: 3.53, 95% confidence interval: 1.35-9.24, p = 0.01), advanced stage disease (p = 0.045), deep myometrial invasion (p = 0.045), and distant metastasis (p < 0.01). In EC with deep myometrial invasion, matrix metalloproteinase (MMP) 2 was highly expressed along with LSR. Anti-LSR mAb significantly inhibited the tumor growth in EC cell xenograft mouse model (tumor volume, 407.1 mm3 versus 726.3 mm3, p = 0.019). Pathway enrichment analysis identified the mitogen-activated protein kinase (MAPK) pathway as a signaling pathway associated with LSR expression. Anti-LSR mAb suppressed the activity of MAPK in vivo. In vitro assays using EC cell lines demonstrated that LSR regulated cell proliferation, invasion, and migration through MAPK signaling, particularly MEK/ERK signaling and membrane-type 1 MMP (MT1-MMP) and MMP2. Moreover, ERK1/2-knockdown suppressed cell proliferation, invasion, migration, and the expression of MT1-MMP and MMP2. CONCLUSIONS: Our results suggest that LSR contributes to tumor growth, invasion, metastasis, and poor prognosis of EC through MAPK signaling. Anti-LSR mAb is a potential therapeutic agent for EC.

BACKGROUND: In Japan, in June 2013, The Ministry of Health, Labor and Welfare (MHLW) decided to temporarily suspend its official recommendation for the participation of girls in the national immunization program. The HPV vaccination rate in Japan soon declined to below 1%. In October 2020, the MHLW notified that the municipalities could and should begin to individually notify girls and their parents targeted for routine vaccination. We have examined how that type of individual notification has affected the number of vaccinations. METHODS: From 12 municipalities (with a combined total population of approximately 4.06 million), we collected vaccination data for all girls who attended grades 6 through 10 from April 2019 to March 2021. We analyzed the number of initial-round vaccinations that occurred by month and the timing and the subjects of the individual notifications. RESULTS: The annual vaccination rate for tenth-grade students in 2020 in the six municipalities that had implemented individual notification was 9.46% (342/3618), which was significantly higher than the rate of 3.22% (54/1676) in the three municipalities that had not implemented individual notification (p < 0.001). On the other hand, the annual vaccination rate for the sixth to ninth-grade students in 2020 in the six municipalities that had implemented individual notification was not significantly (p = 0.56) higher than the rate in the three municipalities that did not: 1.43% (197/13,785) versus 1.33% (83/6260), respectively. CONCLUSION: This study clearly demonstrates the importance of providing information for routine vaccination directly to the targets and their parents.

BACKGROUND: In Japan, HPV vaccination rates has dramaticaly declined since 2013. Since mothers are the ones making the decision to vaccinate their daughters against HPV, we probed the mothers' intention to receive vaccinations for themselves and to vaccinate their daughters against HPV, and their reasoning. METHODS: An internet survey was conducted in March of 2021. Through the screening, 1576 participants were extracted from a survey panel and divided into 3 groups based on their daughter's birth fiscal year (Group 1: 1994 to 1999, Group 2: 2000 to 2003, Group3: 2004 to 2008). The chi-square test and residual analysis were used for the statistical analysis of comparison among the groups. Logistic regression analysis was used to identify independent variables with mothers intention to get their daughters vaccinated under specific situations. RESULTS: The percentage of respondents without anxiety regarding their daughter's general vaccination was significantly higher in Group 1 (p < 0.05). In the mothers of daughters born in or after 2000 when vaccination rates declined (Groups 2 and 3), a situation in which 'The daughter's best friends were vaccinated before her' made the mothers think positively about HPV vaccination, and to the same degree as a situation in which 'You received a notice from your local government recommending vaccination' (Group 2: 41.6% (214/514) and 40.5% (208/514), Group 3: 48.5% (257/530) and 47.0% (249/530)). CONCLUSION: If mothers who have had their daughters vaccinated were to recommend HPV vaccination to their close friends, 'the best friend effect' should promote others to be vaccinated.

BACKGROUND: In Japan, the government suspended HPV vaccine recommendation in 2013, resulting in dropping vaccination uptake to almost zero. We conducted four serial surveys on our colleague' attitude to HPV vaccination between 2014 and 2021. Here, we evaluate the result of the survey in 2021 and compare it to previous surveys. METHODS: The subjects were 567 obstetricians and gynecologists who had been trained in our university hospital or our affiliated hospitals. We used a questionnaire similar in format to those used in 2014, 2017, and 2019. RESULTS: A total of 340 doctors (60.0%) completed the survey. Among them, 93.2% (317/340) of respondents thought that the government should restart HPV vaccination recommendation, and that 63.2% (215/340) think male teenagers should also vaccinate against HPV. The percentage of teenaged daughters inoculated with HPV vaccination after Japanese government had suspended its recommendation was 43.5% (20/46), an increasing trend from the previous surveys. 39 out of the 46 daughters (84.8%) would be expected to receive full HPV vaccination after they take junior high school entrance examination or after 9-valent HPV vaccination is designated as a national routine-immunization. CONCLUSION: This study revealed increasing number of our colleagues think HPV vaccination is necessary for prevention of cervical cancer. The Japanese government's decision to resume its recommendation of the HPV vaccine in November 2021 will lead to a change in the public's thinking and behavior toward the HPV vaccine.

BACKGROUND: In recent years, feelings of isolation among mothers caring for small children has become a significant social issue in Japan. The purpose of this study is to develop a message to alleviate their loneliness, to evaluate the impact of social networking sites (SNS) for delivering such messages, and to propose means of more effective information transmission to promote health for mothers raising small children. METHODS: Our study was conducted in two stages, first an interview and then a cross-sectional study of the mothers involving a questionnaire survey. The interview was targeted two public-health nurses caring for mothers. Based on these interviews, we developed six messages intended to alleviate the mothers' sense of loneliness, which were vetted by seven mothers. The second stage was to conduct a questionnaire survey of mothers both before and after our selected message as advertisement on Instagram and analyzed the effect. The surveys were collected during routine child health check-ups in the City of Takatsuki, Japan. RESULTS: From the six draft messages created based on interviews with public health nurses, we selected the message that most relieves the feeling of loneliness of the mothers who are raising small children. The survey questionnaire was taken by 494 mothers prior to our posting of Instagram advertisements (ads), and afterwards by 419 mothers. The percentage of mothers feeling loneliness tended to decrease after reading the messages (before ads.:8.1%, after ads.:5.8%). 8.6% of the mothers (36/419) remembered seeing the Instagram ads. Mothers with financial anxiety were significantly more likely to have remembered seeing the Instagram ads (p < 0.01). CONCLUSIONS: Our results indicate that usefulness of SNS messaging for mothers raising small children may reduce their feeling of loneliness. Among the SNS, disseminating child-rearing information on Instagram may be more effective for people with financial instability.

AIM: In Japan, in 2013, following reports of several alleged adverse reactions in young girls following vaccination, the previously successful national human papillomavirus infection (HPV) vaccination program collapsed rapidly. In the 8 years since vaccination rates have hovered near zero. In October of 2020, in an attempt to mitigate this lingering disaster, the Japanese Ministry of Health, Labor, and Welfare (MHLW) agency finally revised its HPV vaccination informational leaflet that was designed to be distributed by local governments nationwide. Prior to this revision, Toyonaka City, in Japan's Osaka province, had already begun sending out their own unique leaflet to girls in the targeted 6th-10th grades. As a preview of how MHLW's revised leaflet might eventually succeed, we have studied the HPV vaccination results from Toyonaka City's experiment. METHOD: This study was a population-based analysis that compared the monthly rates of new vaccinations in girls of a targeted grade school age group. We looked at rates before and after the leaflets were sent by Toyonaka City's Division of Health Promotion and Senior Services. RESULTS: The vaccination rates between April 2020 and March 2021 were improved across all grades; 1.2% in 6th grade (p = 0.000185), 2.5% in 7th grade (p < 0.0001), 3.5% in 8th grade (p < 0.0001), 6.8% in 9th grade (p < 0.0001), and a remarkable 16.5% in 10th grade (p < 0.0001). CONCLUSION: When a local government sends an HPV informational leaflet targeted at young girls, it can significantly improve their HPV vaccination rates.

This study aimed to investigate the cytotoxicity of a cluster of differentiation 70 antibody-drug conjugate (CD70-ADC) against ovarian cancer in in vitro and in vivo xenograft models. CD70 expression was assessed in clinical samples by immunohistochemical analysis. Western blotting and fluorescence-activated cell sorting analyses were used to determine CD70 expression in the ovarian cancer cell lines A2780 and SKOV3, and in the cisplatin-resistant ovarian cancer cell lines A2780cisR and SKOV3cisR. CD70 expression after cisplatin exposure was determined in A2780 cells transfected with mock- or nuclear factor (NF)-κB-p65-small interfering RNA. We developed an ADC with an anti-CD70 monoclonal antibody linked to monomethyl auristatin F and investigated its cytotoxic effect. We examined 63 ovarian cancer clinical samples; 43 (68.3%) of them expressed CD70. Among patients with advanced stage disease (n = 50), those who received neoadjuvant chemotherapy were more likely to exhibit high CD70 expression compared to those who did not (55.6% [15/27] vs 17.4% [4/23], P < .01). CD70 expression was confirmed in A2780cisR, SKOV3, and SKOV3cisR cells. Notably, CD70 expression was induced after cisplatin treatment in A2780 mock cells but not in A2780-NF-κB-p65-silenced cells. CD70-ADC was cytotoxic to A2780cisR, SKOV3, and SKOV3cisR cells, with IC50 values ranging from 0.104 to 0.341 nmol/L. In A2780cisR and SKOV3cisR xenograft models, tumor growth in CD70-ADC treated mice was significantly inhibited compared to that in the control-ADC treated mice (A2780cisR: 32.0 vs 1639.0 mm3 , P < .01; SKOV3cisR: 232.2 vs 584.9 mm3 , P < .01). Platinum treatment induced CD70 expression in ovarian cancer cells. CD70-ADC may have potential therapeutic implications in the treatment of CD70 expressing ovarian cancer.

BACKGROUND: Although ovarian clear cell carcinoma (CCC) is associated with high incidence of thromboembolism, the clinicopathological and biological significance of hypercoagulable status in CCC remains unclear. MATERIALS AND METHODS: We retrospectively analyzed pretreatment D-dimer levels, thromboembolic status, and clinical outcome of 125 CCCs in the discovery set and 143 CCCs in two other independent validation sets. Next, we performed RNA sequencing of 93 CCCs and compared coagulation-related gene profiles with 2492 pan-cancer data. We investigated differences in molecular characteristics of CCC subclasses based on coagulation status. RESULTS: In the discovery dataset, D-dimer elevation above the normal range was significantly associated with shorter progression-free and overall survival, irrespective to thromboembolic status. Multivariate analysis identified D-dimer elevation and clinical stage as an independent prognostic factors. We confirmed the prognostic significance of D-dimer elevation in the validation sets. Tissue factor and IL6, which are considered key elements of cancer-induced hypercoagulation, were highly expressed in CCC than in other cancers regardless of D-dimer level. Higher activity of various oncogenic pathways was observed in CCC with compared to without D-dimer elevation. Moreover, hierarchical cluster analysis divided 57 CCCs with D-dimer elevation into immunologically hot and cold tumor subtypes. Hot tumors were characterized by enrichment of T-cell inflamed phenotype, inflammation, the epithelial-mesenchymal transition, and high serum levels of CRP, and cold tumors by enrichment of cell cycle and MYC pathways. CONCLUSIONS: CCC represents hypercoagulable disease and elevate D-dimer is a prognostic factor for decreased survival in CCC. D-dimer high CCC has distinct molecular characteristics into the inflammatory-driven pathway (hot tumor) and the immune-suppressive pathway (cold tumor). Treatment implication of our proposed molecular classification merits further investigation.

BACKGROUND: The retained products of conception (RPOC) and related conditions (RPOC-ARC) are the main cause of secondary postpartum hemorrhage (sPPH), but there is no clear consensus for their management. The purpose of this study was to characterize those RPOC-ARC that require invasive treatment and those that could be managed more conservatively. METHODS: We retrospectively analyzed 96 cases of RPOC-ARC that occurred after miscarriage, abortion, or delivery at a gestational age between 12 and 42 completed weeks, that were managed within our institution from May 2015 to August 2020. We reviewed the associations between the occurrence of sPPH requiring invasive treatment with clinical factors such as the maternal background and the characteristics of the lesions. RESULTS: The range of gestational age at delivery in our study was 12-21 weeks in 61 cases, 22-36 in 5, and 37 or later in 30. Among them, nine cases required invasive procedures for treatment. The onset of sPPH was within one month of delivery in all but two cases, with a median of 24 days (range 9-47). We found significant differences between requirements for invasive versus non-invasive strategies according to gestational age at delivery, assisted reproductive technology (ART) pregnancy, amount of blood loss at delivery, and the long axis of the RPOC-ARC lesion (p = 0.028, p = 0.009, p = 0.004, and p = 0.002, respectively). Multivariate analysis showed that only the long axis of the lesion showed a significant difference (p = 0.029). The Receiver Operating Characteristic (ROC) curve for predicting the need for invasive strategies using the long axis of the lesion showed that with a cutoff of 4.4 cm, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) was 87.5, 90.0, 43.8, and 98.7%, respectively. CONCLUSION: The long axis of the RPOC-ARC is a simple indicator for predicting which sPPH will require invasive procedures, which use is rare in cases with lesions less than 4.4 cm or those occurring after the first postpartum month. Conservative management should be considered in such cases.

AIM: A feeling of isolation childcare mothers' face is a serious social problem in Japan because the relationships with mothers and local communities have grown sparser. The purpose of this study was to clarify the feelings of isolation of mothers during childcare and the factors related to it. METHODS: We conducted a questionnaire survey in Yao City, Osaka. We mailed out a questionnaire survey of 1293 mothers with infants who had either a 4-month or 42-month routine health checkup during the period from September to December of 2018. RESULTS: There was no association between "feeling lonely while raising my child" and the absence of "people who helped raise my children." On the other hand, it was found that the mothers' inner feelings, such as "I wasn't satisfied with my childcare environment" (OR: 2.55, 95% CI: 1.32-4.91, p = 0.0052) or "I lacked confidence in my own childcare abilities" (OR: 6.21, 95% CI: 4.31-8.95, p < 0.0001), were associated with their sense of loneliness. CONCLUSIONS: Mothers' "sense of loneliness" was shown to be best correlated with their dissatisfaction with the environment of their childcare and with their lack of confidence in raising their own children.

BACKGROUND: HPV vaccines are well known to prevent several devastating HPV-associated cancers-when administered before sexual activity begins. We have previously found that mothers in Japan play an important role in a young girl's vaccination decision-making, and that educational intervention with the mothers positively changed their attitude towards the HPV vaccine. The role of fathers is still unclear. We report here similar effects can be achieved by an educational intervention with the fathers. METHOD: We conducted an online survey of 1648 Japanese fathers as having 13-18 year-old daughters. In this group, 1450 fathers had HPV-unvaccinated daughters. Roughly half, 721, were supplied an educational sheet concerning cervical cancer, which included information regarding the safety and efficacy of the HPV vaccine, the other 729 did not receive the sheet. Afterwards, a self-administered questionnaire obtained information from both groups of fathers. We evaluated their attitudes and intentions to inoculate their daughters and willingness to be associated with the vaccination decision-making process. RESULTS: Paternal education with an information sheet was associated with an increased odds ratio for changing the father's attitude in a positive direction, but it was not associated with improving the father's intention to their have their daughters inoculated, nor the father's willingness to be associated with the decision-making process. CONCLUSION: While educational intervention can promote a father's positive attitude towards HPV vaccination, it is ineffective at promoting a positive intention to follow through to inoculate their daughters or improving their willingness to assist in the decision-making process.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rapidly progressive and often fatal pulmonary disease induced by tumor emboli within the small pulmonary arteries. PTTM presents clinically as progressive hypoxia and pulmonary hypertension. Most cases of PTTM are caused by an adenocarcinoma of the stomach. We present the first case report of PTTM caused by cervical squamous cell carcinoma. An 82-year-old woman presented with vaginal bleeding and exertional dyspnea. A cervical mass biopsy showed squamous cell carcinoma. Computed tomography revealed ground glass opacity of the bilateral peripheral lung fields. Hypoxia and pulmonary hypertension gradually worsened after admission. Treatment for acute heart failure was started, but was ineffective. She died of respiratory failure 31 days after admission. She was diagnosed at autopsy as having PTTM induced by cervical squamous cell carcinoma. PTTM needs to be considered in any patient with advanced cancer and lung-related issues to rule out metastatic disease, even in the absence of imaging findings.

PURPOSE: We retrospectively analyzed the differential clinical features and prognosis of endometrial carcinomas arising from the lower uterus, which are reported to have a poorer prognosis than those arising from the upper uterus. METHODS: 246 patients with endometrial carcinoma who underwent surgery were entered as subjects. RESULTS: Twenty-three were classified as having lower uterine segment carcinomas (LUSC); the remaining 223 were upper uterine segment carcinomas (UUSC). LUSC cases were associated with a more advanced FIGO stage than UUSC (p < 0.001). Deep myometrial invasion and lymph node metastasis were more common in LUSC than in UUSC (p = 0.006 and p < 0.001, respectively). LUSC cases demonstrated significantly shorter overall survival (OS) and progression-free survival (PFS) than UUSC (p = 0.02 and p < 0.001, respectively). Multivariate cox proportional hazards analysis demonstrated that the hazard ratio for LUSC was 1.769 for OS and 3.479 for PFS. For endometrial carcinoma survival, FIGO stage and histological type were extracted as independent variables. CONCLUSIONS: LUSC is a high-risk indicator for poorer prognosis for endometrial carcinoma because it is associated with more advanced stage disease, deep myometrial invasion and lymph node metastasis, and indicates a significantly worsened PFS probability. Our analysis concludes that LUSC is FIGO stage-dependent and an important factor for OS.

RESUMO
In 2013, the Ministry of Health, Labor, and Welfare (MHLW) in Japan announced a suspension of the governmental recommendation for routine HPV vaccinations. In 2020, MHLW started individual notifications of HPV vaccine to the targeted girls. In April 2022, the governmental recommendation was restarted, and catch-up vaccinations started. We evaluated the benefits and limitations of the MHLW's new vaccination strategies by estimating the lifetime risk for cervical cancer for each birth FY under different scenarios to suggest a measure for the vaccine suspension generation. It was revealed that catch-up immunization coverage among the unvaccinated must reach as high as 90% in FY2022, when the program begins, in order to reduce the risk of the females already over the targeted ages to the same level or lower than that of women born in FY1994-1999 who had high HPV vaccination rates. For women whose vaccination coverage waned because of their birth FYs, strong recommendations for cervical cancer screening should be implemented.
RESUMO
The present study created an artificial intelligence (AI)-automated diagnostics system for uterine cervical lesions and assessed the performance of these images for AI diagnostic imaging of pathological cervical lesions. A total of 463 colposcopic images were analyzed. The traditional colposcopy diagnoses were compared to those obtained by AI image diagnosis. Next, 100 images were presented to a panel of 32 gynecologists who independently examined each image in a blinded fashion and diagnosed them for four categories of tumors. Then, the 32 gynecologists revisited their diagnosis for each image after being informed of the AI diagnosis. The present study assessed any changes in physician diagnosis and the accuracy of AI-image-assisted diagnosis (AISD). The accuracy of AI was 57.8% for normal, 35.4% for cervical intraepithelial neoplasia (CIN)1, 40.5% for CIN2-3 and 44.2% for invasive cancer. The accuracy of gynecologist diagnoses from cervical pathological images, before knowing the AI image diagnosis, was 54.4% for CIN2-3 and 38.9% for invasive cancer. After learning of the AISD, their accuracy improved to 58.0% for CIN2-3 and 48.5% for invasive cancer. AI-assisted image diagnosis was able to improve gynecologist diagnosis accuracy significantly (P<0.01) for invasive cancer and tended to improve their accuracy for CIN2-3 (P=0.14).
