RESUMEN

The WHO recommends the use of human papillomavirus (HPV) testing for primary cervical cancer (CC) screening because of its high sensitivity. However, triage is desirable to correctly identify HPV+ women who have high-grade lesions (CIN2+) and require treatment. The ANRS-12375 study was conducted in Côte d'Ivoire, Burkina Faso and Cambodia to assess the performance, feasibility and benefits of different triage options for detecting CIN2+ lesions: partial (HPV16 and HPV16/18/45) and extended genotyping, visual inspection (VIA) alone and VIA combined with partial genotyping. VIA was performed by gynecologists. The sensitivity, specificity, and diagnostic likelihood ratio (DLR) of each triage option for detecting CIN2+ lesions with histology as a reference standard were calculated. Of the 2253 women living with HIV (WLHIV) included, 932 (41%) were HPV+. A CIN2+ lesion was identified in 105 (13%) of the 777 participants with histopathology results. The sensitivity of VIA as a triage test for CIN2+ patients was 89%, while that for extended genotyping was 89%, that for HPV16/18/45 partial genotyping was 51%, and that for HPV16 partial genotyping was 36%. The specificities for these tests were 45%, 29%, 72%., and 85%, respectively. Combining VIA and/or partial genotyping positivity slightly increased the sensitivity (94%) at the cost of lower specificity (28%). There was significant intersite heterogeneity (p = .04). Among the three triage tests with a sensitivity ≥85%, the VIA had the highest specificity and positive likelihood ratio (p < .001). VIA and extended genotyping, whether independent or combined, are good triage options with high sensitivity for identifying WLHIV needing treatment for CIN2+.

RESUMEN

OBJECTIVE: To assess the impact of thermal ablation (TA) for the treatment of cervical dysplasia on fertility and pregnancy outcomes among women screened for cervical cancer in Cameroon. DESIGN: Retrospective cohort study. SETTING: Dschang health district, Cameroon. POPULATION: Participants aged 30-45 years from two screening trials conducted between 2015 and 2020 in Dschang District Hospital. METHODS: Participants were primarily screened for human papillomavirus infection, triaged by visual inspection and treated by TA if needed. Between October 2021 and March 2022, interviews on subsequent fertility were conducted with participants treated by TA and a control group of untreated women. MAIN OUTCOME MEASURES: Pregnancy and miscarriage after screening/treatment. RESULTS: A total of 760 participants (219 treated and 541 untreated) completed the survey, with a mean follow-up time of 1297 days. Sixty-two women (28.3%) treated by TA reported a pregnancy postscreening versus 165 (30.5%) in the control group (p = 0.550). Adjusted for potential confounders, the hazard ratio of pregnancy for treated compared with untreated women was 0.82 (0.54-1.24, p = 0.350). Among women reporting pregnancies with a known outcome and which were not voluntarily terminated, 18 (35.3%) treated participants had a miscarriage versus 31 (21.4%) in the control group (p = 0.048). In the adjusted model, no association remained between TA and miscarriage (1.04, 0.39-2.78, p = 0.935). CONCLUSIONS: In our study population, TA did not significantly impact fertility nor miscarriage risk. Our results support the widespread use of TA as a treatment of choice for precancerous cervical lesions in low-income settings.

RESUMEN

Female genital mutilation or cutting (FGM/C) is a practice involving the partial or complete removal of the external female genitalia for non-medical reasons. To facilitate attitude changes, the ecological model of behavior change considers multiple levels of influence and their relationships with environmental and behavioral factors. The combined effects of migration and cultural adaptation result in a transformative process that leads to decreased support for FGM/C. This qualitative study aimed to gain knowledge from FGM/C field professionals regarding the factors promoting behavioral changes in migrant communities in Geneva, Switzerland. Between September and October 2023, we conducted semi-structured interviews using a reflexive thematic analysis. Our qualitative research is reported in accordance with the COREQ criteria. A data analysis was performed using NVivo 14 software. Four influential dimensions were identified, each with associated factors. The first dimension, the social level, includes (1) the impact and implementation of anti-FGM/C laws. The second dimension, the community level, encompasses four factors such as (2) religion, (3) a multifaceted examination of social aspects, (4) navigating language barriers and raising awareness, and (5) cultural adaptation processes. The third dimension, the interpersonal level, includes factors such as (6) changing views on the marriage prerequisite. Finally, the fourth dimension, the personal level, is associated with (7) women's experiences and perspectives regarding FGM/C. The findings highlight seven environmental factors, both within and across dimensions of the ecological model, that interact with human behavior to enable an adaptive cultural process. This process influences changes in attitudes and behaviors regarding FGM/C.

RESUMEN

BACKGROUND: Cervical cancer is the fourth most frequent cancer among women, with 90% of cervical cancer-related deaths occurring in low- and middle-income countries like Cameroon. Visual inspection with acetic acid is often used in low-resource settings to screen for cervical cancer; however, its accuracy can be limited. To address this issue, the Swiss Federal Institute of Technology Lausanne and the University Hospitals of Geneva are collaborating to develop an automated smartphone-based image classifier that serves as a computer aided diagnosis tool for cancerous lesions. The primary objective of this study is to explore the acceptability and perspectives of women in Dschang regarding the usage of a screening tool for cervical cancer relying on artificial intelligence. A secondary objective is to understand the preferred form and type of information women would like to receive regarding this artificial intelligence-based screening tool. METHODS: A qualitative methodology was employed to gain better insight into the women's perspectives. Participants, aged between 30 and 49 were invited from both rural and urban regions and semi-structured interviews using a pre-tested interview guide were conducted. The focus groups were divided on the basis of level of education, as well as HPV status. The interviews were audio-recorded, transcribed, and coded using the ATLAS.ti software. RESULTS: A total of 32 participants took part in the six focus groups, and 38% of participants had a primary level of education. The perspectives identified were classified using an adapted version of the Technology Acceptance Model. Key factors influencing the acceptability of artificial intelligence include privacy concerns, perceived usefulness, and trust in the competence of providers, accuracy of the tool as well as the potential negative impact of smartphones. CONCLUSION: The results suggest that an artificial intelligence-based screening tool for cervical cancer is mostly acceptable to the women in Dschang. By ensuring patient confidentiality and by providing clear explanations, acceptance can be fostered in the community and uptake of cervical cancer screening can be improved. TRIAL REGISTRATION: Ethical Cantonal Board of Geneva, Switzerland (CCER, N°2017-0110 and CER-amendment n°4) and Cameroonian National Ethics Committee for Human Health Research (N°2022/12/1518/CE/CNERSH/SP). NCT: 03757299.


Globally, cervical cancer is the fourth most frequent cancer among women. However, 90% of all deaths caused by cervical cancer occur in low-and middle-income countries. Methods traditionally used in settings like Cameroon to detect cervical cancer unfortunately lack accuracy. Therefore, researchers at the Swiss Federal Institute of Technology Lausanne and the University Hospitals of Geneva are developing an artificial intelligence-based computer aided diagnosis tool to detect pre-cancerous lesions using a smartphone application. The aim of this study was to explore the acceptability and perspectives regarding an AI-based tool for cervical cancer screening for women in Dschang, a city in the west of Cameroon. A qualitative methodology was conducted with six focus groups and a total of 32 participants. The main concerns highlighted by the study are related to privacy, trust in the ability of the healthcare providers, accuracy of the tool as well as the potential negative impact of smartphones. In conclusion, our results show that a computer aided diagnosis tool using artificial intelligence is mostly acceptable to women in Dschang, as long as their confidentiality is preserved, and they are provided with clear explanations beforehand.

RESUMEN

A growing body of evidence indicates a significant decrease in support for female genital mutilation/cutting (FGM/C) within post-migration communities in Western countries. Addressing knowledge gaps and comprehending the factors associated with FGM/C discontinuation in these communities is crucial. The objective of this scoping review is to describe the effects of migration and cultural change on factors supporting FGM/C cessation in migrant communities. The review, from 2012 to 2023, included the following databases: Embase, PubMed, Google Scholar, Swisscovery, CINAHL, APA PsycInfo, and gray literature. Applying the PRISMA-ScR framework, we identified 2819 studies, with 17 meeting the inclusion criteria. The results revealed seven key factors shaping attitudes and behavior toward FGM/C abandonment: (1) legislation against FGM/C, (2) knowing that FGM/C is not a religious requirement, (3) enhancing education about the practice, (4) migration and cultural change, (5) awareness of the harmful effects of FGM/C, (6) a positive view of uncut girls, and (7) a sense of self-agency. These findings highlight factors on a social, community, interpersonal, and personal level that enhance the abandonment of the practice. Further research in the FGM/C field will gain more accuracy in understanding and accounting for these multilevel factors in post-migration settings, offering valuable insights for targeted interventions to promote the cessation of the practice.

RESUMEN

BACKGROUND: Outpatient surgery in gynaecology may offer advantages including cost reduction, patient convenience and hospital bed optimisation without compromising patient safety and satisfaction. With the continual rise in health costs since 2000, outpatient surgery could be a line of action to improve financial resource utilisation and a solution for continuing to treat patients during crises such as the coronavirus disease 2019 pandemic. OBJECTIVE: This systematic review provides an overview of the literature on minimally invasive outpatient hysterectomy for benign indications. METHOD: A focused systematic review of the medical literature between 2018 and 2022 on outpatient gynaecological surgery for a benign indication was conducted using the PubMed and Google Scholar search engines. We then narrowed our selection to articles that referred to hysterectomy. Successful same-day discharge (SDD) was defined as the patient's return home on the day of the procedure without an overnight stay. RESULTS: Fifteen articles that focused on minimally invasive surgery were included in this review. Most of the studies (n = 11) were conducted in the United States. Outpatient surgery had a mean success rate of 60 % and a mean readmission rate of 3 %. The main reasons for SDD failure were patient choice, failed voiding, the need for pain management, nausea or vomiting, or both and the late timing of surgery. SDD was not associated with more complications and readmissions compared with inpatient care. The three main attribute predictors of SDD were young age, early timing of surgery and short total operative time. Patient satisfaction with SDD was high in absolute terms and relative to satisfaction with hospitalisation. CONCLUSION: Minimally invasive outpatient hysterectomy for a benign indication is feasible and safe but is associated with a notable risk of failure. To increase the success rate of outpatient management, patients must be well selected and surgery pathways must be planned in advance. The implementation of enhanced recovery protocols may help promote outpatient hysterectomy for a benign indication.

RESUMEN

Clear cell carcinoma is a rare and very aggressive subset of cervical cancer, with poor outcome if diagnosed at advanced stage. There are few data available on the optimal management of this histotype, and treatment recommendations that include surgery and chemoradiotherapy, are essentially based on those for squamous cell carcinoma. Here we report the case of a young patient newly diagnosed with advanced stage (FIGO IIB) clear cell carcinoma of the uterine cervix who received a window of opportunity one injection of nivolumab followed by standard chemoradiotherapy. She showed a persistent complete remission after 28 months of follow-up, but developed hypothyroidism, as a consequence of immunotherapy, and required lifelong thyroid hormone replacement.

RESUMEN

OBJECTIVE: To determine whether knowledge of cytology affects the colposcopist's diagnostic accuracy in the identification of cervical intraepithelial neoplasia grade 2 and worse (≥ CIN2). METHOD: In this cross-over study, healthcare professionals interpreted colposcopy images from 80 patient cases with known histological diagnoses. For each case, 2 images taken with a colposcope were provided (native and after acetic acid application). Inclusion criteria consisted of women with a transformation zone type 1 or 2, who had both a cytological and histological diagnosis. Cases were distributed across two online surveys, one including and one omitting the cytology. A wash-out period of six weeks between surveys was implemented. Colposcopists were asked to give their diagnosis for each case as < CIN2 or ≥ CIN2 on both assessments. Statistical analysis was conducted to compare the two interpretations. RESULTS: Knowledge of cytology significantly improved the sensitivity when interpreting colposcopic images, from 51.1% [95%CI: 39.3 to 62.8] to 63.7% [95%CI: 52.1 to 73.9] and improved the specificity from 63.5% [95%CI: 52.3 to 73.5] to 76.6% [95%CI: 67.2 to 84.0]. Sensitivity was higher by 38.6% when a high-grade cytology (ASC-H, HSIL, AGC) was communicated compared to a low-grade cytology (inflammation, ASC-US, LSIL). Specificity was higher by 31% when a low-grade cytology was communicated compared to a high-grade. CONCLUSIONS: Our data suggests that knowledge of cytology increases sensitivity and specificity for diagnosis of ≥ CIN2 lesions at colposcopy. Association between cytology and histology may have contributed to the findings.

RESUMEN

BACKGROUND: Screening participation at recommended intervals is a crucial component of cervical cancer prevention effectiveness. However, little is known regarding the rate of re-screening in a Sub-Saharan context. This study aimed to estimate the re-screening rate of women in a semi-rural after an initial HPV-based screening and identify factors that influence adherence. METHODS: This cohort study at the Annex Regional Hospital of Dschang enrolled women screened for cervical cancer over 5 years ago and due for re-screening. Women who initially tested HPV-positive (n = 132) and a random sample of HPV-negative women (n = 220) participated in a telephone survey between October 2021 and March 2022 to assess re-screening participation and reasons. Sociodemographic factors were collected, and associations with rescreening were evaluated. RESULTS: A total of 352 participants aged under 50 years (mean age 37.4 years) were contacted, and 203 (58.0%) completed the survey. The proportion of women who complied with the screening recommendation was 34.0% (95% CI 27.5% - 40.5%), The weighted re-screening proportion was 28.4%. Age, marital status, education level, type of employment, and place of residence were not associated with the rate of re-screening. Main reported barriers to re-screening were lack of information (39.0%), forgetfulness (39.0%), and impression of being in good health (30.0%). Women who remembered the recommended screening interval were 2 to 3 times more likely to undergo re-screening (aOR (adjusted odds ratio) = 2.3 [1.2-4.4], p = 0.013). Human papilloma virus- positive status at the initial screening was also associated with the re-screening((aOR) (95% CI): 3.4 (1.8-6.5). CONCLUSION: Following an initial Human Papilloma Virus-based screening campaign in the West Region of Cameroon, one third of women adhered to re-screening within the recommended timeframe. Existing screening strategies would benefit from developing better information approaches to reinforce the importance of repeated cervical cancer screening.

RESUMEN

Screening Papanicolaou test samples has proven to be highly effective in reducing cervical cancer-related mortality. However, the lack of trained cytopathologists hinders its widespread implementation in low-resource settings. Deep learning-assisted telecytology diagnosis emerges as an appealing alternative, but it requires the collection of large annotated training datasets, which is costly and time-consuming. In this paper, we demonstrate that the abundance of unlabeled images that can be extracted from Pap smear test whole slide images presents a fertile ground for self-supervised learning methods, yielding performance improvements compared to off-the-shelf pre-trained models for various downstream tasks. In particular, we propose Cervical Cell Copy-Pasting (C3P) as an effective augmentation method, which enables knowledge transfer from public and labeled single-cell datasets to unlabeled tiles. Not only does C3P outperforms naive transfer from single-cell images, but we also demonstrate its advantageous integration into multiple instance learning methods. Importantly, all our experiments are conducted on our introduced in-house dataset comprising liquid-based cytology Pap smear images obtained using low-cost technologies. This aligns with our long-term objective of deep learning-assisted telecytology for diagnosis in low-resource settings.

RESUMEN

INTRODUCTION: Transvaginal natural orifice transluminal endoscopic surgery (vNOTES) has already proven its non-inferiority to conventional abdominal laparoscopy (CAL) for hysterectomy without conversion. The results in terms of efficacy and safety are promising. However, we note a lack of medical literature and no specific randomised controlled trial assessing women's sexual function after vNOTES for benign adnexal surgery. The aim of this RCT is to confirm the non-inferiority of the vNOTES approach for benign adnexal pathology compared with CAL on women's sexual function. Secondary outcomes will evaluate vNOTES's efficiency, morbidity and postoperative complications compared with CAL for benign adnexal surgery. The relationship between adnexal mass morcellation and the quality of the histological analysis will also be evaluated as secondary outcome. METHODS AND ANALYSIS: Women aged 18-70 years undergoing a benign adnexal surgery at the Geneva University Hospitals will be eligible and randomised with a 1:1 ratio to the CAL arm or the vNOTES arm, if inclusion criteria are met. Participants will complete the Female Sexual Function Index, the Couple Satisfaction Index-16 and a self-reported questionnaire on dyspareunia within 4 weeks prior to randomisation and at 3+6 months after surgery. General and clinical data will be collected when the patient is enrolled in the study, during hospitalisation and at 1 month postoperative to assess secondary outcomes.An absence of impairment on sexual function will be confirmed with a stability or an improvement of the evaluated scores in each group at 3 and 6 months postoperative compared with the preoperative scores. We expect to have no statistically significant difference in sexuality questionnaires scores between the two groups. ETHICS AND DISSEMINATION: Protocol of this study was validated by the Cantonal Research Ethics Commission of Geneva, Switzerland, on 9 August 2022. We aim to publish the study's results in peer-reviewed journals within 3 years. TRIAL REGISTRATION NUMBER: NCT05761275.

RESUMEN

Uterine leiomyoma is the most common benign tumour of the uterus in women of reproductive age. When removed surgically, a mini-invasive procedure is preferentially used (laparoscopic or robotic) and the extraction of the specimen can be managed by power morcellation. In this consecutive case-series, we present three cases of parasitic leiomyoma that appeared following previous surgical management of leiomyoma using the technique of laparoscopic myomectomy with uncontained power morcellation. The time frame in between the initial surgery and the diagnosis of the parasitic leiomyoma was 5.7 years. All three patients were diagnosed with endometriosis: 2 cases prior to the initial surgery and 1 case after the initial surgery. One hypothesis could be that, due to pelvic inflammation, endometriosis is a risk factor for iatrogenic parasitic leiomyoma development in case of uncontained morcellation of leiomyoma during myomectomy.

RESUMEN

Visual inspection with acetic acid (VIA) is one of the methods recommended by the World Health Organization for cervical cancer screening. VIA is simple and low-cost; it, however, presents high subjectivity. We conducted a systematic literature search in PubMed, Google Scholar and Scopus to identify automated algorithms for classifying images taken during VIA as negative (healthy/benign) or precancerous/cancerous. Of the 2608 studies identified, 11 met the inclusion criteria. The algorithm with the highest accuracy in each study was selected, and some of its key features were analyzed. Data analysis and comparison between the algorithms were conducted, in terms of sensitivity and specificity, ranging from 0.22 to 0.93 and 0.67 to 0.95, respectively. The quality and risk of each study were assessed following the QUADAS-2 guidelines. Artificial intelligence-based cervical cancer screening algorithms have the potential to become a key tool for supporting cervical cancer screening, especially in settings where there is a lack of healthcare infrastructure and trained personnel. The presented studies, however, assess their algorithms using small datasets of highly selected images, not reflecting whole screened populations. Large-scale testing in real conditions is required to assess the feasibility of integrating those algorithms in clinical settings.

RESUMEN

Pigment epithelium-derived factor (PEDF) is a secreted glycoprotein involved in various biological processes. Its expression declines during ovarian carcinogenesis where it could decrease macrophages polarization, inhibit angiogenesis and induce apoptosis. Altogether, PEDF represents an ideal anti-cancer agent against ovarian cancer. We previously proposed the non-viral Sleeping Beauty transposon (SBT) system to stably integrate the PEDF transgene into ovarian cancer cells. Here, we report the development of liposomes and lipid nanoparticles for SBT-PEDF gene therapy. We determined that the SBT-PEDF nanolipid delivery system was the best system to increase the expression of PEDF in ovarian cancer spheroids. We also developed an ex vivo model of ovarian tumors which allowed us to show that nanolipoplexe in combination to paclitaxel exhibits synergistic and effective anti-tumor efficacy on ovarian tumors. These findings demonstrate that lipid nanoparticle for SBT-PEDF gene therapy may be a promising therapeutic approach for ovarian cancer.

RESUMEN

Human papillomavirus (HPV) is a common sexually transmitted disease that has been linked to both cancer and reproductive health issues. While its impact on fertility and pregnancy success has been studied, there is still too little evidence about the influence of HPV on assisted reproductive technology (ART). Therefore, there exists a need for HPV testing in couples undergoing infertility treatments. Infertile men have been found to have a higher prevalence of seminal HPV infection, which can compromise sperm quality and reproductive function. As such, it could be important to investigate the correlation between HPV and ART outcomes in order to improve the quality of evidence. Understanding the potentially detrimental effects of HPV on ART outcomes may have promising important implications for the management of infertility. This minireview summarizes the so far limited developments in this area and highlights the major need for further well-designed studies to address this issue.

RESUMEN

INTRODUCTION: Cytology is an option for triaging human papillomavirus (HPV)-positive women. The interpretation of cytologic slides requires expertise and financial resources that are not always available in resource-limited settings. A solution could be offered by manual preparation and digitization of slides on site for real-time remote cytologic diagnosis by specialists. In the present study, we evaluated the operational feasibility and cost of manual preparation and digitization of thin-layer slides and the diagnostic accuracy of screening with virtual microscopy. MATERIALS AND METHODS: Operational feasibility was evaluated on 30 cervical samples obtained during colposcopy. The simplicity of the process and cellularity and quality of digitized thin-layer slides were evaluated. The diagnostic accuracy of digital versus glass slides to detect cervical intraepithelial neoplasia grade 2 or worse was assessed using a cohort of 264 HPV-positive Cameroonian women aged 30 to 49 years. The histologic results served as the reference standard. RESULTS: Manual preparation was found to be feasible and economically viable. The quality characteristics of the digital slides were satisfactory, and the mean cellularity was 6078 squamous cells per slide. When using the atypical squamous cells of undetermined significance or worse threshold for positivity, the diagnostic performance of screening digital slides was not significantly different statistically compared with the same set of slides screened using a light microscope (P = 0.26). CONCLUSIONS: We have developed an innovative triage concept for HPV-positive women. A quality-ensured telecytologic diagnosis could be an effective solution in areas with a shortage of specialists, applying a same day "test-triage-treat" approach. Our results warrant further on-site clinical validation in a large prospective screening trial.

RESUMEN

PURPOSE: Thermal ablation (TA) has become the conventional method for treatment of precancerous cervical lesions in low-resource settings. After TA, both the squamocolumnar junction (SCJ) and the transformation zone (TZ) may be subject to change. Our aim was to evaluate SCJ and TZ variability after TA. METHODS: Study data were collected in a large prospective trial of a cervical cancer screening campaign in Cameroon. For each patient, two sets of cervical photos (native and with acetic acid) were taken before and 6-12 months after TA. The SCJ and TZ were evaluated independently by three observers according to the WHO nomenclature. When discordances were observed between the type of TZ and SCJ selected by each observer, a corrected TZ was established on the basis of the SCJ categorization. Interobserver agreement for TZ interpretation was evaluated using Cohen's kappa coefficient for agreement between two observers and Fleiss' kappa between three observers. RESULTS: Fifty consecutive participants were included in the analysis. Seventy-six percent were interpreted as TZ1-2, and 24% as TZ3 before TA. In 56% of cases, the entire SCJ could not be entirely visualized after TA, thus being recategorized as TZ3. Interobserver agreement was fair for diagnosis before TA (Kappa coefficient, 0.34; 95% CI, 0.27 to 0.45) and moderate for diagnosis after TA (Kappa coefficient, 0.40; 95% CI, 0.30 to 0.50). After TA, 36% progressed from TZ1-2 to TZ3, with a moderate interobserver agreement (Kappa coefficient, 0.44; 95% CI, 0.40 to 0.54). CONCLUSION: We observed a shift of the SCJ into the endocervical canal after TA. A significant proportion of participants had TZ 3 after treatment, raising the question of visual inspection with acetic acid's applicability as a first-line follow-up examination method after TA.
