ObjectiveTo evaluate disease-free survival of cervical conization prior to radical hysterectomy in patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2009).MethodsA multicenter retrospective observational cohort study was conducted including patients from the Surgery in Cervical Cancer Comparing Different Surgical Aproaches in Stage IB1 Cervical Cancer (SUCCOR) database with FIGO 2009 IB1 cervical carcinoma treated with radical hysterectomy between January 1, 2013, and December 31, 2014. We used propensity score matching to minimize the potential allocation biases arising from the retrospective design. Patients who underwent conization but were similar for other measured characteristics were matched 1:1 to patients from the non-cone group using a caliper width ≤0.2 standard deviations of the logit odds of the estimated propensity score.ResultsWe obtained a weighted cohort of 374 patients (187 patients with prior conization and 187 non-conization patients). We found a 65% reduction in the risk of relapse for patients who had cervical conization prior to radical hysterectomy (hazard ratio (HR) 0.35, 95% confidence interval (CI) 0.16 to 0.75, p=0.007) and a 75% reduction in the risk of death for the same sample (HR 0.25, 95% CI 0.07 to 0.90, p=0.033). In addition, patients who underwent minimally invasive surgery without prior conization had a 5.63 times higher chance of relapse compared with those who had an open approach and previous conization (HR 5.63, 95% CI 1.64 to 19.3, p=0.006). Patients who underwent minimally invasive surgery with prior conization and those who underwent open surgery without prior conization showed no differences in relapse rates compared with those who underwent open surgery with prior cone biopsy (reference) (HR 1.94, 95% CI 0.49 to 7.76, p=0.349 and HR 2.94, 95% CI 0.80 to 10.86, p=0.106 respectively).ConclusionsIn this retrospective study, patients undergoing cervical conization before radical hysterectomy had a significantly lower risk of relapse and death.

Abstract Introduction Complications of copper load intrauterine devices, including ectopic pregnancies are well reported. Rates of ectopic pregnancy are 0.6 to 1.1% per year. However, the levonorgestrel intrauterine device has been described as more protective against ectopic pregnancies due to the addition of the hormone levonorgestrel. The hormone released from the intrauterine device causes some systemic effects, but local effects such as glandular atrophy and stromal decidualization, in addition to foreign body reaction, are dominant. Few case reports have described ampullary ectopic pregnancies. However, we report, for the first time, a major complication of levonorgestrel intrauterine device: a cornual pregnancy. Case presentation A 36-year-old Caucasian nulliparous woman presented with complaints of progressive nausea, abdominal pain and irregular vaginal bleeding for 2 months. For 3 years, she had been using a levonorgestrel intrauterine device. A two-dimensional transvaginal sonogram noted a sac situated external to the endometrial cavity in the right cornua of the uterus with an empty uterus. She was successfully treated with chemotherapy. Conclusion Many complications have been described, including ectopic pregnancies, using copper intrauterine devices. The levonorgestrel-releasing intrauterine system is a particularly good choice for adolescents because of associated non-contraceptive benefits such as decreased menstrual bleeding, dysmenorrhea and pain associated with endometriosis 1. Yet a cornual pregnancy following the use of a levonorgestrel intrauterine device is a complication which, to our knowledge, has not been described before. Physicians prescribing this type of intrauterine device should be aware of this rare event.

- Abstract
Objective: Treatment of cervical cancer patients in Uganda is hampered by late diagnosis due to the unavailability of timely screening and limited availability of advanced cancer care. This study evaluated the clinical presentation and management of cervical cancer patients presenting at the Uganda Cancer Institute (UCI) in Kampala, the tertiary oncology facility in Uganda with access to radiotherapy and reflected on daily clinical practice to identify priority areas for improving cervical cancer care in Uganda., Patients and Methods: We retrospectively analyzed medical records of all cervical cancer patients presenting to UCI between January 2017 and March 2018 for sociodemographic characteristics and clinical variables with descriptive statistics. The clinical management of patients with early and advanced stage disease who initiated treatment at UCI was evaluated using the national targets formulated in the Uganda strategic plan for cervical cancer prevention and control., Results: Medical records of 583 patients were included, representing less than 10% of the annual estimated incidence in Uganda. The majority (86%) of patients presented with advanced stage of disease. More than half of patients never initiated (31%) or interrupted (30%) treatment. The national treatment targets for surgery (10%) and palliative care (25%) were achieved for eligible patients at UCI, however, the target for chemoradiotherapy (65%) was not met., Conclusion: Daily clinical practice differed from the ambitions formulated in the national treatment targets on cervical cancer control. While most women presented in advanced stage requiring chemoradiotherapy, the target was not met due to limited availability of radiotherapy. Although targets for surgery and palliative care were achieved at UCI facility level, they mask the unmet need of the majority of cervical cancer patients who never initiated or completed treatment. This demands for further expansion of oncological surgical capacity, chemotherapy and radiotherapy and warrants to focus on accessible prevention programs., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2025 de Fouw et al.

- Abstract
Objectives: The World Health Organization supports both the screen-and-treat (ST) approach and the screen, triage and treat (STT) approach to cervical cancer screening using high-risk human papillomavirus (hrHPV) testing. For Uganda, the sequence of hrHPV-ST and hrHPV-STT could be similar, with visual inspection with acetic acid (VIA) after positive hrHPV tests in both. To consider potential tradeoffs (overtreatment in ST versus missed cancer cases in STT), we compared hrHPV-STT with VIA triage (STT-VIA), and STT with HPV 16/18 genotyping risk stratification, to hrHPV-ST for Uganda, in terms of overtreatment, cervical cancer incidence, and life years, for the general female population of Uganda., Methods: A microsimulation model of cervical cancer was adapted. Incremental benefit-harm ratios of STT were calculated as ratios of prevented overtreatment to reduced life years, and to increased cancer cases. Additional scenarios with 20% difference in intra- and inter-screening follow-up between ST and STT were modeled., Results: Both STT strategies resulted in life year losses on average compared to ST. STT-VIA prevented more overtreatment but led to increased cervical cancer incidence and life year losses. STT-G-VIA resulted in better harm-benefit ratios and additional costs. With better follow-up, STT prevented overtreatment and improved outcomes., Discussion: For Uganda, the STT approach appears preferrable, if the screening sequences of hrHPV-based ST and STT are similar in practice. While VIA triage alone would reduce overtreatment the most, it could also result in more cancer cases. Risk stratification via genotyping could improve STT. Potential follow-up differences and resource availability should be considered by decision-makers when planning Uganda's hrHPV-based screening strategy., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Sultanov et al.

- Abstract
Background: Uganda has a high burden of cervical cancer and its current coverage of screening based on visual inspection with acetic acid (VIA) is low. High-risk HPV (hrHPV) testing is recommended by the World Health Organization as part of the global elimination strategy for cervical cancer. In this context, country-specific health economic evaluations can inform national-level decisions regarding implementation. We evaluated the recommended hrHPV screen-and-treat strategy to determine the minimum required levels of coverage and treatment adherence, as well as the maximum price level per test, for the strategy to be cost-effective in Uganda., Methods: We conducted a headroom analysis to estimate potential room for spending on implementing the hrHPV screen-and-treat strategy at different levels of coverage and treatment adherence (from 10% to 100%) at each screening round, and at different price levels of the hrHPV test. We compared the strategy with the existing VIA-based screen-and-treat policy in Uganda. We calculated headroom as the product of number of life years gained by the strategy and the willingness-to-pay threshold, minus the incremental costs incurred by the strategy. Positive headroom was interpreted as an indication of cost-effectiveness., Results: Compared with VIA-based screening with low 5% coverage, the hrHPV screen-and-treat strategy required at least 30% coverage and adherence for positive mean headroom, and compared with 30% VIA-based screening coverage, the minimum levels were 60%. At 60% coverage and adherence, the maximum acceptable price per hrHPV test was found to be between 15 and 30 international dollars., Conclusions: The hrHPV-based screen-and-treat strategy could be cost-effective in Uganda if the screening coverage and treatment adherence are at least 30% in each screening round, and if the price per test is set below 30 international dollars. The minimum required levels of screening coverage and adherence to treatment provide potential starting points for decision-makers in planning the rollout of hrHPV testing. The headroom estimates can guide the planning costs of screening infrastructure and campaigns to achieve the required coverage and treatment adherence in Uganda., Competing Interests: Disclosure of interest: The authors completed the ICMJE Disclosure of Interest Form (available upon request from the corresponding author) and disclose no relevant interest., (Copyright © 2024 by the Journal of Global Health.

- Abstract
Introduction: In Bangladesh, the uptake of cervical cancer screening is low. Lack of knowledge and understanding of symptoms and risk factors contributes to low screening uptake. The purpose of this study was to explore the knowledge of cervical cancer risk factors and symptoms and to measure the association with socio-demographic characteristics among women and household decisionmakers living in hard-to-reach areas of Bangladesh., Methods: A cross-sectional survey was conducted in five districts in Bangladesh among women aged between 30 and 60 years, their husbands, and their mothers-in-law from April to September 2022. Data were collected using a modified version of the validated AWACAN questionnaire tool. The significance level was considered at p-value <0.05 and odds ratios with 95% confidence., Results: Nearly 50% of participating women in hard-to-reach areas of Bangladesh and their family decisionmakers had low levels of knowledge of the risk factors and symptoms of cervical cancer. Only 20% of respondents in our survey knew about HPV, the most important risk factor for developing cervical cancer. Most respondents were familiar with the terminology of cervical cancer as a disease; however, approximately 40% of respondents did not know that not adhering to cervical cancer screening could be seen as a risk factor. Women do not make decisions about participation in cervical cancer screening on their own. Knowledge of cervical cancer risk factors and symptoms among decisionmakers was significantly associated with higher education and higher household monthly expenditure., Conclusion: Women, their husbands, and mothers-in-law in hard-to-reach areas of Bangladesh had limited knowledge about cervical cancer risk factors and symptoms. Engaging these key decision-makers in targeted health education is vital to improve screening uptake. Conduction of future research to identify and address screening barriers is also essential for effective prevention efforts., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Nazrul et al.

- Abstract
Objectives: Imaging is increasingly used to assess lymph node involvement in clinically early-stage cervical cancer. This retrospective study aimed to evaluate the diagnostic accuracy of MRI, CT, and [
18 F]FDG-PET-CT., Methods: Women with International Federation of Gynaecology and Obstetrics (FIGO) 2009 stage IA2-IIA cervical cancer and pretreatment imaging between 2009 and 2017 were selected from the Netherlands Cancer Registry. Patient-based and region-based (i.e. pelvic and common iliac) nodal status was extracted from radiology reports. Pathology results were considered the reference standard for calculating accuracy indices. Multiple imputation was used for missing pathology to limit verification bias risk., Results: Nodal assessment was performed in 1676 patients with MRI, 926 with CT, and 379 with [18 F]FDG-PET-CT, with suspicious nodes detected in 17%, 16%, and 48%, respectively. [18 F]FDG-PET-CT was used to confirm MRI/CT results in 95% of patients. Pathology results were imputed for 30% of patients. [18 F]FDG-PET-CT outperformed MRI and CT in detecting patient-based nodal metastases with sensitivities of 80%, 48%, and 40%, and AUCs of 0.814, 0.706, and 0.667, respectively, but not in specificity: 79%, 92%, and 92%. Region-based analyses showed similar indices in the pelvic region, but worse performance in the common iliac region with AUCs of 0.575, 0.554, and 0.517, respectively., Conclusions: [18 F]FDG-PET-CT outperformed MRI and CT in detecting nodal metastases, which may be related to its use as a verification modality. However, MRI and CT had the highest specificity. As MRI is generally performed routinely to assess local and regional spread of cervical cancer, [18 F]FDG-PET-CT can be used to confirm suspicious nodes., Critical Relevance Statement: Accurate assessment of the nodal status in clinically early-stage cervical cancer is essential for tumour staging, treatment decision making and prognosis., Key Points: • The accuracy of MRI, CT or [18 F]FDG-PET-CT for nodal staging in early cervical cancer is a subject of discussion. • Overall, [18 F]FDG-PET-CT outperformed MRI, followed by CT, when used as a verification modality. • Staging with MRI and the addition of [18 F]FDG-PET-CT to verify high-risk cases seems to be a good approach., (© 2024.

- Abstract
Background: The optimal follow-up strategy to detect recurrence after fertility-sparing surgery for early stage cervical cancer is unknown. Tailored surveillance based on individual risks could contribute to improved efficiency and, subsequently, reduce costs in health care. The aim of this study was to establish the predictive value of cervical cytology and high-risk human papillomavirus (HPV) testing to detect recurrent cervical intraepithelial neoplasia grade 2 or worse (CIN2+; including recurrent cervical cancer) after fertility-sparing surgery., Methods: In this nationwide, population-based, retrospective cohort study, we used data from the Netherlands Cancer Registry and the Dutch Nationwide Pathology Databank. All patients aged 18-40 years with cervical cancer of any histology who received fertility-sparing surgery (ie, large loop excision of the transformation zone, conisation, or trachelectomy) between Jan 1, 2000, and Dec 31, 2020, were included. Pathology data from diagnosis, treatment, and during follow-up were analysed. The primary and secondary outcomes were the cumulative incidence of recurrent CIN2+ and recurrence-free survival, overall and stratified by results for cytology and high-risk HPV., Findings: 1548 patients were identified, of whom 1462 met the inclusion criteria. Of these included patients, 19 568 pathology reports were available. The median age at diagnosis was 31 years (IQR 30-35). After a median follow-up of 6·1 years (IQR 3·3-10·8), recurrent CIN2+ was diagnosed in 128 patients (cumulative incidence 15·0%, 95% CI 11·5-18·2), including 52 patients (cumulative incidence 5·4%, 95% CI 3·7-7·0) with recurrent cervical cancer. The overall 10-year recurrence-free survival for CIN2+ was 89·3% (95% CI 87·4-91·3). By cytology at first follow-up visit within 12 months after fertility-sparing surgery, 10-year recurrence-free survival for CIN2+ was 92·1% (90·2-94·1) in patients with normal cytology, 84·6% (77·4-92·3) in those with low-grade cytology, and 43·1% (26·4-70·2) in those with high-grade cytology. By high-risk HPV status at first follow-up visit within 12 months after surgery, 10-year recurrence-free survival for CIN2+ was 91·1% (85·3-97·3) in patients who were negative for high-risk HPV and 73·6% (58·4-92·8) in those who were positive for high-risk HPV. Cumulative incidence of recurrent CIN2+ within 6 months after any follow-up visit (6-24 months) in patients negative for high-risk HPV with normal or low-grade cytology was 0·0-0·7% and with high-grade cytology was 0·0-33·3%. Cumulative incidence of recurrence in patients positive for high-risk HPV with normal or low-grade cytology were 0·0-15·4% and with high-grade cytology were 50·0-100·0%. None of the patients who were negative for high-risk HPV without high-grade cytology, at 6 months and 12 months, developed recurrence., Interpretation: Patients who are negative for high-risk HPV with normal or low-grade cytology at 6-24 months after fertility-sparing surgery, could be offered a prolonged follow-up interval of 6 months. This group comprises 80% of all patients receiving fertility-sparing surgery. An interval of 12 months seems to be safe after two consecutive negative tests for high-risk HPV with an absence of high-grade cytology, which accounts for nearly 75% of all patients who receive fertility-sparing surgery., Funding: KWF Dutch Cancer Society., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2023 Elsevier Ltd.

- Abstract
Introduction: Visual inspection with acetic acid is limited by subjectivity and a lack of skilled human resource. A decision support system based on artificial intelligence could address these limitations. We conducted a diagnostic study to assess the diagnostic performance using visual inspection with acetic acid under magnification of healthcare workers, experts, and an artificial intelligence algorithm., Methods: A total of 22 healthcare workers, 9 gynecologists/experts in visual inspection with acetic acid, and the algorithm assessed a set of 83 images from existing datasets with expert consensus as the reference. Their diagnostic performance was determined by analyzing sensitivity, specificity, and area under the curve, and intra- and inter-observer agreement was measured using Fleiss kappa values., Results: Sensitivity, specificity, and area under the curve were, respectively, 80.4%, 80.5%, and 0.80 (95% CI 0.70 to 0.90) for the healthcare workers, 81.6%, 93.5%, and 0.93 (95% CI 0.87 to 1.00) for the experts, and 80.0%, 83.3%, and 0.84 (95% CI 0.75 to 0.93) for the algorithm. Kappa values for the healthcare workers, experts, and algorithm were 0.45, 0.68, and 0.63, respectively., Conclusion: This study enabled simultaneous assessment and demonstrated that expert consensus can be an alternative to histopathology to establish a reference standard for further training of healthcare workers and the artificial intelligence algorithm to improve diagnostic accuracy., Competing Interests: Competing interests: KP and SG were involved in development of the Artificial Intelligence algorithm., (© IGCS and ESGO 2023.

- Abstract
Introduction: In early-stage vulvar squamous cell carcinoma (VSCC) a sentinel lymph node (SLN) procedure is regarded successful if at least one SLN is removed with minimal residual radioactivity. An inguinofemoral lymphadenectomy is considered if not all SLNs visualized on lymphoscintigraphy can be found, with subsequent increased morbidity. We correlated lymphoscintigraphy findings with surgical outcome and groin recurrence with focus on number of SLNs found., Methods: This study concerns a retrospective cohort of 171 women treated for early-stage VSCC who underwent a SLN procedure between 2000 and 2020. The risk of groin recurrence was compared after either a successful or complete SLN procedure, i.e. removal of all SLNs that were visualized on lymphoscintigraphy., Results: In 13 (7.6%) groins of 171 patients SLN visualization on lymphoscintigraphy failed. In 230 of the 246 (93.5%) groins in which a SLN was visualized, at least one SLN was found during surgery. In 224 of the 246 (91.1%) groins the SLN procedure was regarded either successful (n = 14) or complete (n = 210). An isolated groin recurrence was documented in 5 out of 192 (2.6%, 95%-CI; 0.34 to 4.9) SLN-negative groins after a median follow-up of 47.0 months. All recurrences were noted in the complete SLN group (5/180 groins). The difference with the successful SLN group (0/12 groins) was not significant., Conclusion: Risk of groin recurrence was 2.6% after SLN negative biopsy in early-stage VSCC. The risk appeared not increased if at least one SLN was found with minimal residual radioactivity, in case more SLNs were visualized on lymphoscintigraphy., (© 2023 The Author(s).

- Abstract
Introduction: Evidence-based preventive strategies for cervical cancer in low-resource setting have been developed, but implementation is challenged, and uptake remains low. Women and girls experience social and economic barriers to attend screening and human papillomavirus (HPV) vaccination programs. Male support has been proven successful in uptake of other reproductive healthcare services. This qualitative study with focus groups aimed to understand the perspectives of males on cervical cancer screening and HPV vaccination in Western-Uganda This knowledge could be integrated into awareness activities to increase the attendance of cervical cancer screening and HPV vaccination programs., Materials and Methods: Focus group discussions were conducted with men aged 25 to 60 years, who were married and/or had daughters, in Kagadi district, Mid-Western Uganda. All interviews were transcribed verbatim and thematically analyzed using an inductive approach., Results: Eleven focus group discussions were conducted with 67 men. Men were willing to support their wives for screening and their daughters for HPV vaccination. Misperceptions such as family planning and poor personal hygiene leading to cervical cancer, and misperception of the preventative aspect of screening and vaccination were common. Women with cervical cancer suffer from stigmatization and family problems due to loss of fertility, less marital sexual activity, domestic violence and decreased economic productivity., Conclusions: Ugandan men were willing to support cervical cancer prevention for their wives and daughters after being informed about cervical cancer. Limited knowledge among men about the risk factors and causes of cervical cancer, and about the preventative aspect of HPV vaccination and screening and their respective target groups, can limit uptake of both services. Screening and vaccination programs should actively involve men in creating awareness to increase uptake and acceptance of prevention., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 de Fouw et al.

- Abstract
Objective: Standard surgical treatment of advanced-stage ovarian carcinoma with electrosurgery cannot always result in complete cytoreductive surgery (CRS), especially when many small metastases are found on the mesentery and intestinal surface. We investigated whether adjuvant use of a neutral argon plasma device can help increase the complete cytoreduction rate., Patients and Methods: 327 patients with FIGO stage IIIB-IV epithelial ovarian cancer (EOC) who underwent primary or interval CRS were randomized to either surgery with neutral argon plasma (PlasmaJet) (intervention) or without PlasmaJet (control group). The primary outcome was the percentage of complete CRS. The secondary outcomes were duration of surgery, blood loss, number of bowel resections and colostomies, hospitalization, 30-day morbidity, and quality of life (QoL)., Results: Complete CRS was achieved in 119 patients (75.8%) in the intervention group and 115 patients (67.6%) in the control group (risk difference (RD) 8.2%, 95% confidence interval (CI) -0.021 to 0.181; P = 0.131). In a per-protocol analysis excluding patients with unresectable disease, complete CRS was obtained in 85.6% in the intervention group and 71.5% in the control group (RD 14.1%, 95% CI 0.042 to 0.235; P = 0.005). Patient-reported QoL at 6 months after surgery differed between groups in favor of PlasmaJet surgery (95% CI 0.455-8.350; P = 0.029). Other secondary outcomes did not differ significantly., Conclusions: Adjuvant use of PlasmaJet during CRS for advanced-stage ovarian cancer resulted in a significantly higher proportion of complete CRS in patients with resectable disease and higher QoL at 6 months after surgery.

- Abstract
Background: High-risk human papillomavirus (hrHPV) testing has been recommended by the World Health Organization as the primary screening test in cervical screening programs. The option of self-sampling for this screening method can potentially increase women's participation. Designing screening programs to implement this method among underscreened populations will require contextualized evidence., Methods: PREvention and SCReening Innovation Project Toward Elimination of Cervical Cancer (PRESCRIP-TEC) will use a multi-method approach to investigate the feasibility of implementing a cervical cancer screening strategy with hrHPV self-testing as the primary screening test in Bangladesh, India, Slovak Republic and Uganda. The primary outcomes of study include uptake and coverage of the screening program and adherence to follow-up. These outcomes will be evaluated through a pre-post quasi-experimental study design. Secondary objectives of the study include the analysis of client-related factors and health system factors related to cervical cancer screening, a validation study of an artificial intelligence decision support system and an economic evaluation of the screening strategy., Discussion: PRESCRIP-TEC aims to provide evidence regarding hrHPV self-testing and the World Health Organization's recommendations for cervical cancer screening in a variety of settings, targeting vulnerable groups. The main quantitative findings of the project related to the impact on uptake and coverage of screening will be complemented by qualitative analyses of various determinants of successful implementation of screening. The study will also provide decision-makers with insights into economic aspects of implementing hrHPV self-testing, as well as evaluate the feasibility of using artificial intelligence for task-shifting in visual inspection with acetic acid., Trial Registration: ClinicalTrials.gov, NCT05234112 .

- Abstract
Objective: Treatment strategies for bulky lymph nodes in patients with locally advanced cervical cancer scheduled for definitive chemoradiation include nodal boosting with radiotherapy, surgical debulking, or both. The aim of this retrospective cohort study was to compare survival and toxicity in patients receiving these treatments and to compare them with a group that received neither form of treatment., Methods: Women diagnosed between January 2009 and January 2017 with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB2, IIA2-IVA cervical cancer with lymph nodes ≥1.5 cm without upper limit on pretreatment imaging and treated with definitive chemoradiation were selected from the Netherlands Cancer Registry. Patients were categorized by intention-to-treat strategy: boosting, debulking, or neither treatment, with subgroup analysis for patients receiving both treatments, that is, debulking with boosting. Overall and relapse-free survival outcomes were compared by Kaplan-Meier and Cox regression analyses and toxicity by logistic regression analysis., Results: Of 190 patients, 101 (53%) received only nodal boosting, 31 (16%) debulking alone, 29 (15%) debulking combined with boosting, and 29 (15%) received neither treatment. The 5 year overall and relapse-free survival for the treatment groups were 58%, 45% and 45% (p=0.19), and 47%, 44% and 46% (p=0.87), respectively. Multivariable Cox regression analyses demonstrated no differences in overall and relapse-free survival. Combination of debulking with boosting was associated with decreased overall and relapse-free survival compared with debulking alone (HR 2.47, 95% CI 1.22 to 5.00; and HR 2.37, 95% CI 1.14 to 4.93). Nodal boosting was independently associated with a decreased toxicity risk compared with debulking strategy (OR 0.37, 95% CI 0.16 to 0.83)., Conclusions: This study showed no survival benefit from either nodal boosting or debulking strategy in patients with suspicious bulky nodes. Nodal boosting might, however, be associated with less toxicity. Dual treatment with debulking and boosting showed a worse survival outcome because this group probably represents patients with poor prognostic factors., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2022.

- Abstract
Introduction: Comprehensive updated information on cervical cancer surgical treatment in Europe is scarce., Objective: To evaluate baseline characteristics of women with early cervical cancer and to analyze the outcomes of the ESGO quality indicators after radical hysterectomy in the SUCCOR database., Methods: The SUCCOR database consisted of 1272 patients who underwent radical hysterectomy for stage IB1 cervical cancer (FIGO 2009) between January 2013 and December 2014. After exclusion criteria, the final sample included 1156 patients. This study first described the clinical, surgical, pathological, and follow-up variables of this population and then analyzed the outcomes (disease-free survival and overall survival) after radical hysterectomy. Surgical-related ESGO quality indicators were assessed and the accomplishment of the stated recommendations was verified., Results: The mean age of the patients was 47.1 years (SD 10.8), with a mean body mass index of 25.4 kg/m
2 (SD 4.9). A total of 423 (36.6%) patients had a previous cone biopsy. Tumor size (clinical examination) <2 cm was observed in 667 (57.7%) patients. The most frequent histology type was squamous carcinoma (794 (68.7%) patients), and positive lymph nodes were found in 143 (12.4%) patients. A total of 633 (54.8%) patients were operated by open abdominal surgery. Intra-operative complications occurred in 108 (9.3%) patients, and post-operative complications during the first month occurred in 249 (21.5%) patients, with bladder dysfunction as the most frequent event (119 (10.3%) patients). Clavien-Dindo grade III or higher complication occurred in 56 (4.8%) patients. A total of 510 (44.1%) patients received adjuvant therapy. After a median follow-up of 58 months (range 0-84), the 5-year disease-free survival was 88.3%, and the overall survival was 94.9%. In our population, 10 of the 11 surgical-related quality indicators currently recommended by ESGO were fully fulfilled 5 years before its implementation., Conclusions: In this European cohort, the rate of adjuvant therapy after radical hysterectomy is higher than for most similar patients reported in the literature. The majority of centers were already following the European recommendations even 5 years prior to the ESGO quality indicator implementations., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2021.

- Abstract
Introduction: In Ethiopia there is an extensive unmet need for palliative care, while the burden of non-communicable diseases and cancer is increasing. This study aimed to explore palliative care needs and preferences of patients, their caregivers, and the perspective of stakeholders on service provision in palliative programs for women, mostly affected by cervical cancer and breast cancer., Methods: A rapid program evaluation using a qualitative study approach was conducted in three home-based palliative care programs in Addis Ababa and Yirgalem town, Ethiopia. Female patients enrolled in the programs, and their primary caregivers were interviewed on palliative care needs, preferences and service provision. We explored the views of purposely selected stakeholders on the organization of palliative care and its challenges. Audio-taped data was transcribed verbatim and translated into English and an inductive thematic analysis was applied. Descriptive analyses were used to label physical signs and symptoms using palliative outcome scale score., Results: A total of 77 interviews (34 patients, 12 primary caregivers, 15 voluntary caregivers, 16 stakeholders) were conducted. The main physical complaints were moderate to severe pain (70.6%), followed by anorexia (50.0%), insomnia, nausea and vomiting (41.2%). Social interaction and daily activities were hampered by the patients' condition. Both patients and caregivers reported that programs focus most on treatment of symptoms, with limited psychosocial, emotional, spiritual and economic support. Lack of organizational structures and policy directions limit the collaboration between stakeholders and the availability of holistic home-based palliative care services., Conclusions: Although female patients and caregivers appreciated the palliative care and support provided, the existing services did not cover all needs. Pain management and all other needed supports were lacking. Multi-sectorial collaboration with active involvement of community-based structures is needed to improve quality of care and access to holistic palliative care services., Competing Interests: EA is executive director of Hospice Ethiopia. MF and JJ provided training and supervision of cervical cancer screening activities via the Female Cancer Foundation for the EFCI program. The authors declare they have no competing interests. This does not alter our adherence to PLOS ONE policies on sharing data and materials.

- Abstract
Objective: The aim of this study was to assess the superiority of ICG-
99m Tc-nanocolloid for the intraoperative visual detection of sentinel lymph nodes (SLNs) in vulvar squamous cell carcinoma (VSCC) patients compared to standard SLN detection using99m Tc-nanocolloid with blue dye., Methods: In this multicenter, randomized controlled trial, VSCC patients underwent either the standard SLN procedure or with the hybrid tracer ICG-99m Tc-nanocolloid. The primary endpoint was the percentage of fluorescent SLNs compared to blue SLNs. Secondary endpoints were successful SLN procedures, surgical outcomes and postoperative complications., Results: Forty-eight patients were randomized to the standard (n = 24) or fluorescence imaging group (n = 24) using ICG-99m Tc-nanocolloid. The percentage of blue SLNs was 65.3% compared to 92.5% fluorescent SLNs (p < 0.001). A successful SLN procedure was obtained in 92.1% of the groins in the standard group and 97.2% of the groins in the fluorescence imaging group (p = 0.33). Groups did not differ in surgical outcome, although more short-term postoperative complications were documented in the standard group (p = 0.041)., Conclusions: Intraoperative visual detection of SLNs in patients with VSCC using ICG-99m Tc-nanocolloid was superior compared to99m Tc-nanocolloid and blue dye. The rate of successful SLN procedures between both groups was not significantly different. Fluorescence imaging has potential to be used routinely in the SLN procedure in VSCC patients to facilitate the search by direct visualization., Clinical Trial Registration: Netherlands Trial Register (Trial ID NL7443)., (Copyright © 2020 The Author(s).

- Abstract
Objective: The aim of this study was to assess the impact of the evolving role of the addition of chemotherapy to postoperative radiotherapy on oncological outcomes and toxicity in patients with early-stage cervical cancer after radical hysterectomy., Methods: Retrospective cohort study of patients with stage IB1-IIB FIGO 2009 cervical cancer treated from November 1999 to May 2015 by primary surgery and radiotherapy (46-50.4 Gy in 1.8-2.0 Gy fractions) with or without concurrent cisplatin (40 mg/m
2 , 5-6 weekly cycles) with or without a brachytherapy boost. Chemotherapy was allocated depending on the risk factors for recurrence. Incidences of all outcomes were calculated using Kaplan-Meier's methodology and compared by log-rank tests. Risk factors for recurrence and survival were identified using Cox's proportional hazards models., Results: A total of 154 patients were included, median follow-up was 9.6 years (IQR: 6.1-12.8). Five-year pelvic recurrence-free survival was 75.3%; 74.7% in patients with high-risk factors treated with radiotherapy; and 77.3% in those treated with chemoradiation (P=0.43). Distant metastasis-free survival at 5 years was 63.4%; 63.6% in high-risk patients after radiotherapy; and 57.1% after chemoradiation (P=0.36). Five-year overall survival was 63.9%: 66.8% and 51.6% after radiotherapy and after chemoradiation in patients with high-risk factors (P=0.37), respectively. Large tumor size was a risk factor for vaginal and pelvic recurrence, ≥2 involved lymph nodes was a significant risk factor for para-aortic recurrence and death. Mild treatment-related late toxicity was observed in 53.9% of the patients. Five-year severe (grade 3-5) late rectal, bladder, bowel, and vaginal toxicities were, respectively, 1.3%, 0%, 3.4%, and 0.9%. Any late severe toxicity was observed in 5.5% of patients treated with radiotherapy and in 15.3% of those treated with chemoradiation (P=0.07)., Conclusion: Postoperative (chemo)radiation for early-stage cervical cancer patients with risk factors for recurrence yields adequate pelvic tumor control, but overall survival is limited due to distant metastasis., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2020.

- Abstract
Background: Minimally invasive surgery in cervical cancer has demonstrated in recent publications worse outcomes than open surgery. The primary objective of the SUCCOR study, a European, multicenter, retrospective, observational cohort study was to evaluate disease-free survival in patients with stage IB1 (FIGO 2009) cervical cancer undergoing open vs minimally invasive radical hysterectomy. As a secondary objective, we aimed to investigate the association between protective surgical maneuvers and the risk of relapse., Methods: We obtained data from 1272 patients that underwent a radical hysterectomy by open or minimally invasive surgery for stage IB1 cervical cancer (FIGO 2009) from January 2013 to December 2014. After applying all the inclusion-exclusion criteria, we used an inverse probability weighting to construct a weighted cohort of 693 patients to compare outcomes (minimally invasive surgery vs open). The first endpoint compared disease-free survival at 4.5 years in both groups. Secondary endpoints compared overall survival among groups and the impact of the use of a uterine manipulator and protective closure of the colpotomy over the tumor in the minimally invasive surgery group., Results: Mean age was 48.3 years (range; 23-83) while the mean BMI was 25.7 kg/m
2 (range; 15-49). The risk of recurrence for patients who underwent minimally invasive surgery was twice as high as that in the open surgery group (HR, 2.07; 95% CI, 1.35 to 3.15; P=0.001). Similarly, the risk of death was 2.42-times higher than in the open surgery group (HR, 2.45; 95% CI, 1.30 to 4.60, P=0.005). Patients that underwent minimally invasive surgery using a uterine manipulator had a 2.76-times higher hazard of relapse (HR, 2.76; 95% CI, 1.75 to 4.33; P<0.001) and those without the use of a uterine manipulator had similar disease-free-survival to the open surgery group (HR, 1.58; 95% CI, 0.79 to 3.15; P=0.20). Moreover, patients that underwent minimally invasive surgery with protective vaginal closure had similar rates of relapse to those who underwent open surgery (HR, 0.63; 95% CI, 0.15 to 2.59; P<0.52)., Conclusions: Minimally invasive surgery in cervical cancer increased the risk of relapse and death compared with open surgery. In this study, avoiding the uterine manipulator and using maneuvers to avoid tumor spread at the time of colpotomy in minimally invasive surgery was associated with similar outcomes to open surgery. Further prospective studies are warranted., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2020. No commercial re-use. See rights and permissions.

- Abstract
Aim: Recently, the safety of laparoscopic radical hysterectomy (LRH) has been called into question in early-stage cervical cancer. This study aimed to evaluate overall survival (OS) and disease-free survival (DFS) in patients treated with abdominal radical hysterectomy (ARH) and LRH for early-stage cervical cancer and to provide a literature review., Methods: Patients diagnosed between 2010 and 2017 with International Federation of Gynaecology and Obstetrics (2009) stage IA2 with lymphovascular space invasion, IB1 and IIA1, were identified from the Netherlands Cancer Registry. Cox regression with propensity score, based on inverse probability treatment weighting, was applied to examine the effect of surgical approach on 5-year survival and calculate hazard ratios (HR) and 95% confidence intervals (CIs). Literature review included observational studies with (i) analysis on tumours ≤4 cm (ii) median follow-up ≥30 months (iii) ≥5 events per predictor parameter in multivariable analysis or a propensity score., Results: Of the 1109 patients, LRH was performed in 33%. Higher mortality (9.4% vs. 4.6%) and recurrence (13.1% vs. 7.3%) were observed in ARH than LRH. However, adjusted analyses showed similar DFS (89.4% vs. 90.2%), HR 0.92 [95% CI: 0.52-1.60]) and OS (95.2% vs. 95.5%), HR 0.94 [95% CI: 0.43-2.04]). Analyses on tumour size (<2/≥2 cm) also gave similar survival rates. Review of nine studies showed no distinct advantage of ARH, especially in tumours <2 cm., Conclusion: After adjustment, our retrospective study showed equal oncological outcomes between ARH and LRH for early-stage cervical cancer - also in tumours <2 cm.

- Abstract
Objective: To assess the feasibility, safety, oncological, and obstetric outcomes in patients with cervical tumors >2 cm treated with neoadjuvant chemotherapy in preparation for abdominal radical trachelectomy., Methods: A retrospective analysis of patients with cervical cancer >2 cm (up to 6 cm) was conducted in patients who were selected to receive neoadjuvant chemotherapy before abdominal radical trachelectomy. Surgical and clinical outcomes were examined in relation to radiological and pathological results. In addition, obstetric outcomes were described. The Mann-Whitney U test and Fisher's exact test were performed to compare radiological findings between successful and unsuccessful abdominal radical trachelectomy procedures. International Federation of Gynecology and Obstetrics (FIGO) 2009 staging classification was used for this study., Results: A total of 19 women were treated with neoadjuvant chemotherapy for cervical tumors >2 cm at our institution between May 2006 and July 2018. The median age was 28 years (range 19-36). The distribution of FIGO stages was seven patients stage IB1 (37%), 10 patients stage IB2 (53%), and two patients (10%) stage IIA. Mean clinical tumor size was 4.4 cm (range 3.5-6.0). Histology revealed 74% cases of squamous cell carcinoma. The remaining patients had adenocarcinoma (21%) and only one patient had clear cell adenocarcinoma (5%). Chemotherapy consisted of six weekly cycles of cisplatin (70 mg/m
2 ) and paclitaxel (70 mg/m2 ). In 15 of the 19 patients (74%) fertility was successfully preserved. In the four patients in whom fertility preservation failed, one patient had stable disease after three cycles and did not meet the criteria for fertility-sparing surgery and three patients had intra- or post-operative indications for adjuvant therapy. Three of the 19 patients (15.7%) had a relapse, two of whom died. One case was in the group of successful abdominal radical trachelectomy., Conclusion: Neoadjuvant chemotherapy followed by fertility-sparing surgery may be a feasible and safe option in select patients with cervical tumors >2 cm. Unfavorable prognostic factors are defined as non-responsiveness and non-squamous pathology, which can help in patient selection for fertility-sparing surgery., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2020.

- Abstract
Community mobilisation is an essential part of cervical cancer screening programmes to increase demand for screening services. While there are different methods of community mobilisation, in Ethiopia community conversations during traditional coffee ceremonies appear to be a context appropriate and effective method. Linkage of community mobilisation with existing community networks can increase uptake of cervical cancer screening and improve continuous support and care among community members.

- Abstract
Background: Thermal coagulation is gaining popularity for treating cervical intraepithelial neoplasia (CIN) in screening programs in low- and middle-income countries (LMICs) due to unavailability of cryotherapy., Objectives: Assess the effectiveness of thermal coagulation for treatment of CIN lesions compared with cryotherapy, with a focus on LMICs., Search Strategy: Papers were identified from previous reviews and electronic literature search in February 2018 with publication date after 2010., Selection Criteria: Publications with original data evaluating cryotherapy or thermal coagulation with proportion of cure as outcome, assessed by colposcopy, biopsy, cytology, and/or visual inspection with acetic acid (VIA), and minimum 6 months follow-up., Data Collection and Analysis: Pooled proportions of cure are presented stratified per treatment modality, type of lesion, and region., Main Results: Pooled cure proportions for cryotherapy and thermal coagulation, respectively, were 93.8% (95% CI, 88.5-97.7) and 91.4% (95% CI, 84.9-96.4) for CIN 1; 82.6% (95% CI, 77.4-87.3) and 91.6% (95% CI, 88.2-94.5) for CIN 2-3; and 92.8% (95% CI, 85.6-97.7) and 90.1% (95% CI, 87.0-92.8) for VIA-positive lesions. For thermal coagulation of CIN 2-3 lesions in LMICs 82.4% (95% CI, 75.4-88.6)., Conclusions: Both cryotherapy and thermal coagulation are effective treatment modalities for CIN lesions in LMICs., (© 2019 The Authors.

- Abstract
Background: The most important goal for survival benefit of advanced stage ovarian cancer is to surgically remove all visible tumour, because complete cytoreductive surgery (CCS) has been shown to be associated with prolonged survival. In a remarkable number of women, CCS is very challenging. Especially in women with many small metastases on the peritoneum and intestinal surface, conventional CCS with electrosurgery is not able to be "complete" in removing safely all visible tumour. In this randomized controlled trail (RCT) we investigate whether the use of the PlasmaJet Surgical Device increases the rate of CCS, and whether this indeed leads to a longer progression free and overall survival. The main research question is: does the use of the PlasmaJet Surgical Device in surgery for advanced stage ovarian cancer result in an increased number of complete cytoreductive surgeries when compared with conventional surgical techniques. Secondary study objectives are: 30-day morbidity, duration of surgery, blood loss, length of hospitalisation, Quality of Life, disease-free survival, overall survival, percentage colostomy, cost-effectiveness., Methods: The study design is a multicentre single-blinded superiority RCT in two university and nine non-university hospitals in The Netherlands. Three hundred and thirty women undergoing cytoreductive surgery for advanced stage ovarian carcinoma (FIGO Stage IIIB-IV) will be randomized into two arms: use of the PlasmaJet (intervention group) versus the use of standard surgical instruments combined with electrocoagulation (control group). The primary outcome is the rate of complete cytoreductive surgery in both groups. Secondary study objectives are: 30-day morbidity, duration of surgery, blood loss, length of hospitalisation, Quality of Life, disease-free survival, overall survival, percentage colostomy, cost-effectiveness. Quality of life will be evaluated using validated questionnaires at baseline, at 1 and 6 months after surgery and at 1, 2, 3 and 4 years after surgery., Discussion: We hypothesize the additional value of the use of the PlasmaJet in CCS for advanced stage epithelial ovarian cancer. More knowledge about efficacy, side effects, recurrence rates, cost effectiveness and pathology findings after using the PlasmaJet Device is advocated. This RCT may aid in this void., Trial Registration: Dutch Trial Register NTR6624 . Registered 18 August 2017.

- Abstract
The optimal management of breast cancer susceptibility gene (BRCA)1/2 carriers with isolated serous tubal intraepithelial carcinoma (STIC) found at risk-reducing salpingo-oophorectomy (RRSO) is unclear. The prevalence of occult carcinoma and STIC in a consecutive series of BRCA1/2 carriers undergoing RRSO is reported. The outcome of staging procedures in BRCA1/2 carriers with isolated STIC at RRSO as well as the relationship between staging, chemotherapy treatment and risk of recurrence was assessed via a systematic review of the literature. Our series included 235 BRCA1/2 carriers who underwent RRSO. Federation of Gynaecology and Obstetrics stage IA carcinoma or STIC was found at RRSO in three (1.3%) and two (0.9%) patients, respectively. A systematic review of the literature included 82 BRCA1/2 carriers with isolated STIC found at RRSO. In 13/82 (16%) cases with STIC, staging was reported. In none of these cases staging revealed more advanced disease. Recurrent disease was found in four of 36 patients with reported follow-up. The estimated risk of recurrence in patients with isolated STIC at RRSO was about 11% (95% confidence interval 3-26%) after a median follow-up of 42 months (range 7-138). No recurrences were reported in those patients with STIC at RRSO who underwent staging or received chemotherapy. We found 1.3% occult carcinoma and 0.9% STIC at RRSO in our cohort of BRCA1/2 carriers. A systematic review of the literature suggests that additional treatment after RRSO, i.e. staging and/or chemotherapy, is associated with a lower risk of recurrence. However, data on staging and follow-up are limited., (Copyright © 2018 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.)

- Abstract
Objective: Detection and resection of all malignant lesions is pivotal in staging and cytoreductive surgery (CRS) of endometrial cancer (EC). Intraoperative EC detection could be enhanced using OTL-38, a fluorescent-labelled folate receptor-α (FRα) targeted imaging agent. The objectives of this study were to investigate which subgroups of high-risk EC patients express FRα and assess feasibility of intraoperative EC detection using OTL-38., Results: FRα expression on TMA was significantly correlated with tumor type ( p < 0.01). Eighty-two percent of serous and clear cell carcinomas showed FRα expression. Four patients were enrolled in the clinical study. Using fluorescence imaging all omental ( n = 3) and lymph node (LN) metastases ( n = 16) could be clearly identified, including one otherwise undetected omental metastasis. However, false-positive fluorescence was identified in 17/50 non-metastatic LNs, caused by OTL-38 targeting of FRβ, expressed by tumor-associated activated macrophages., Conclusions: This study describes high FRα expression in serous and clear cell EC and demonstrates the first experience of intraoperative FRα-targeted tumor detection in patients with these subtypes of EC. Although all metastases could be clearly identified using OTL-38, the role of tumor-associated macrophages should be further evaluated., Methods: Immunohistochemical (IHC) staining of FRα expression was performed on tissue micro arrays (TMA) of 116 patients with high-risk EC features. Patients with either serous or clear cell EC, planned for staging or CRS, were eligible for inclusion in the clinical study and received an intravenous dose of 0.0125 mg/kg OTL-38, 2-3 hours prior to surgery. Resected lesions, identified by standard-of-care and/or fluorescence imaging, were histopathologically assessed for FRα and tumor status., Competing Interests: CONFLICTS OF INTEREST The Centre for Human Drug Research (a not-for-profit foundation) and the Leiden University Medical Center received financial compensation, study drug and equipment for the execution of this study from On Target Laboratories LLC.

- Abstract
Background: L1 cell adhesion molecule (L1CAM) has been shown to be a prognostic marker in various cancer types, and has been suggested to play a role in epithelial mesenchymal transition (EMT). Here, we determined the prognostic significance of L1CAM in cervical cancer and its association with vimentin expression on tumor cells, indicative of EMT., Methods: Formalin-fixed, paraffin-embedded primary tumor samples from 372 cervical cancer patients were collected for immunohistochemical analysis of L1CAM expression. In 109 FFPE specimens, the percentage of vimentin expressing tumor cells was determined by flow cytometry., Results: Positive L1CAM expression (≥10% of tumor cells) was associated with disease-free survival, validated using RNAseq TCGA data. L1CAM expression was independently associated with locoregional recurrence-free survival (hazard ratio 2.62, 95% CI 1.33 - 5.17, P = 0.006), and strongly associated with percentage of vimentin expressing tumor cells ( P = 0.003). Expression of both L1CAM and vimentin indicated a subgroup with the highest risk of recurrence (hazard ratio 3.15, 95% CI 1.25 - 7.92, P = 0.015)., Conclusion: L1CAM might be a promising new prognostic marker for locoregional recurrences in cervical cancer, and its association with vimentin expression suggests that L1CAM might affect tumor aggressiveness, possibly through EMT., Competing Interests: CONFLICTS OF INTEREST None

- Abstract
Objective To evaluate progress made at district level in Malawi towards reaching the 5th Millennium Development Goal, the reduction of maternal mortality. Methods In 2006, community-based maternal mortality in Thyolo, Malawi was calculated by applying the 'sisterhood method', a survey that relies on participants responding to basic questions about maternal mortality in their families. Results were compared with a 1989 sisterhood study in the same district. Information on facility-based maternal mortality in 2005 was extracted from district hospital records. Results The community-based maternal mortality ratio (MMR) was calculated as 558 per 100 000 live births (95% CI 260 to 820). A comparison with the MMR from the 1989 survey (409 per 100 000 live births) shows that maternal mortality had not declined. The hospital-based MMR was 994 per 100 000 live births in 2005. Conclusion Maternal mortality in this district has not reduced and may actually have increased. The threat of failure to achieve Millennium Development Goal 5 increases the moral obligation to improve access to quality health care.

- Abstract
Round the clock (24 hours×7 days) HIV testing is vital to maintain a high prevention of mother to child transmission (PMTCT) coverage for women delivering in district health facilities. PMTCT coverage increases when most of the pregnant women will have their HIV status tested. Therefore routine offering of HIV testing should be integrated and seen as a part of comprehensive antenatal care. For women who miss antenatal care and deliver in a health facility without having had their HIV status tested, the labour and maternity ward could still serve as other entry points.

- Abstract
International migration of health care workers from low-income countries to the West has increased considerably in recent years, thereby jeopardizing the achievements of The Millennium Development Goals, especially number 4 (reduction of child mortality) and 5 (improvement of maternal health).This migration, as well as the HIV/AIDS epidemic, lack of training of health care personnel and poverty, are mainly responsible for this health care personnel deficit. It is essential that awareness be raised amongst donors and local governments so that staffing increases, and that infection prevention measures be in place for their health care personnel. Western countries should conduct a more ethical recruitment of health care workers, otherwise a new millennium development goal will have to be created: to reduce the human resources for health crisis.
