RESUMEN

INTRODUCTION: One of the major changes in the revised (2018) FIGO-staging system is the addition of stage IIIC to the previously used 2009 system. We evaluated the prognostic value of positive pelvic and/or para-aortic lymph nodes in patients with cervical cancer. METHODS: A nationwide retrospective cohort study was performed by analyzing data from the Netherlands Cancer Registry. All patients newly diagnosed with stage IB-IVA between 2005 and 2018 were identified. Three-year, 5-year and 15-year overall survival (OS) rates were estimated with the Kaplan-Meier method. RESULTS: Of the included 6082 patients, 1740 patients (29%) had pelvic and/or para-aortic lymph node metastases. For patients with FIGO 2009 stage IB-IB1-IIA-IIA1 and stage IB2-IIA2-IIB with pelvic and/or para-aortic lymph node metastases the OS was significantly different (p < 0.001 and p = 0.009), with a 5-year OS of 77% and 67%, compared with 92% and 74% for women without lymph node metastases. For FIGO 2009 stage IIIA-IIIB-IVA with and without lymph node metastases, survival rates are not significantly different (p = 0.064). For FIGO 2018 stage IIIC the 3y-OS, 5y-OS and 15-year OS are 72%, 65% and 59% respectively. Survival rates of IIIC diagnosed based on imaging (IIICr) are significantly impaired compared to stage IIIC diagnosed based on pathology (IIICp) (p < 0.001). CONCLUSION: Patients with FIGO 2009 stage IB-IIB cervical cancer with pelvic and/or para-aortic lymph node metastases have significantly impaired survival compared to patients without metastases. Survival rates of patients with FIGO 2009 stage IIIA-IVA are not affected by lymph node metastases.

RESUMEN

BACKGROUND: The RAS/RAF/MEK/ERK (MAPK) pathway plays a role in ovarian carcinogenesis. Low-grade serous ovarian carcinoma (LGSOC) frequently harbors activating MAPK mutations. MAPK inhibitors have been used in small subsets of ovarian carcinoma (OC) patients to control tumor growth. Therefore, we performed a meta-analysis to evaluate the effectiveness of MAPK inhibitors in OC patients. We aimed to determine the clinical benefit rate (CBR), the subgroup of MAPK inhibitors with the best CBR and overall response rate (ORR), and the most common adverse events. METHODS: We conducted a search in PubMed, Embase via Ovid, the Cochrane library and clinicaltrials.gov on studies evaluating the efficacy of single MAPK pathway inhibition with MAPK pathway inhibitors in OC patients. Our primary outcome included the CBR, defined by the proportion of patients with stable disease (SD), complete (CR) and partial response (PR). Secondary outcomes included the ORR (including PR and CR) and grade 3 and 4 adverse events. Meta-analysis was performed using a random-effects model. RESULTS: We included nine studies with a total of 319 OC patients, for which we determined a pooled CBR of 63% (95%-CI 39-84%, I2 = 92%). Combined treatment with Raf- and MEK inhibitors in in BRAFv600 mutated LGSOC (n = 6) had the greatest efficacy with a CBR of 100% and ORR of 83%. MEK inhibitors had the best efficacy as a single agent. Subgroup analysis by tumor histology demonstrated a significantly higher CBR and ORR in patients with LGSOC, with a pooled CBR and ORR of 87% (95%-CI 81-92%, I2 = 0%) and 27% (95%-CI 10-48%, I2 = 77%) respectively. Adverse events of grade 3 or higher were reported frequently: 123 in 167 patients. CONCLUSIONS: MEK inhibitors are the most promising single agents in (LGS)OC. However, dual MAPK pathway inhibition should be considered in patients with a BRAFv600 mutation, or non-mutated OC with depleted treatment options due indications of higher efficacy and tolerable toxicity profiles.

RESUMEN

AIMS: Uterine serous carcinoma (USC) is an aggressive subtype of endometrial cancer with high rates of relapse and death. As adjuvant therapy might be beneficial in early-stage disease, the impact of standard complete surgical staging is questioned. Therefore, we wanted to explore the optimal treatment strategy for women diagnosed with USC. MATERIALS AND METHODS: A retrospective multicentre study of women diagnosed with primary USC in the UK and the Netherlands. Treatment strategy in relation to overall survival and progression-free survival was recorded and evaluated with Kaplan-Meier and Cox regression analysis. Furthermore, primary surgical staging and/or adjuvant treatment in relation to patterns of recurrence were evaluated. RESULTS: In total, 272 women with a median age of 70 years were included. Most patients presented with International Federation of Gynecology and Obstetrics (FIGO) stage I disease (44%). Overall, 48% of patients developed recurrent disease, most (58%) with a distant component. Women treated with chemotherapy showed significantly better overall survival (hazard ratio 0.50, 95% confidence interval 0.31-0.81; P = 0.005) and progression-free survival (hazard ratio 0.48, 95% confidence interval 0.28-0.80; P = 0.04) in multivariable analysis. Furthermore, even in surgically staged women with FIGO stage IA disease, a high recurrence rate of 42% was seen. CONCLUSION: Women with USC who received adjuvant chemotherapy showed better survival rates compared with those who received other or no adjuvant treatment. The benefit of adjuvant chemotherapy was observed across all tumour stages, including surgically staged FIGO stage IA. These data question the role of surgical staging in the absence of macroscopic disease in USC.

RESUMEN

INTRODUCTION: Endometriosis is a risk factor for low-grade serous, clear cell, and endometroid ovarian carcinoma. In both endometriosis and ovarian carcinoma, immunological factors are associated with clinical outcome. Chronic inflammation in endometriosis may be linked to tumorigenesis, but exact processes contributing to endometriosis-associated ovarian carcinoma remain unknown. This review aims to describe potential immunological factors involved in the malignant transformation of endometriosis into ovarian carcinoma. METHODS: PubMed and Embase were searched from inception up to October 2020 for studies comparing immunological processes in endometriosis and endometriosis-associated ovarian carcinoma. RESULTS: Detailed analysis of immune components in the malignant transformation of endometriosis into endometriosis-associated ovarian carcinoma is lacking. Altered levels of chemokines and cytokines as IL-6, IL-8, IL-10, and TNF-α are reported and the function, number and polarization of NK cells, dendritic cells, and monocytes differ between endometriosis and associated ovarian carcinoma compared to healthy tissue. In addition, altered inflammasome and complement systems, indicate a role for the immune system in the carcinogenesis of endometriosis. CONCLUSION: Chronic inflammation in endometriosis may potentially drive inflammation-induced carcinogenesis in endometriosis-associated ovarian carcinoma. Exact immunological pathways and cellular processes remain unknown and require more thorough investigation.

RESUMEN

STUDY QUESTION: What is the effect of salpingectomy for ectopic pregnancy or hydrosalpinx at a young age on ovarian cancer risk compared to no salpingectomy for any reason? SUMMARY ANSWER: We found no significant reduction in ovarian cancer risk after salpingectomy for ectopic pregnancy or hydrosalpinx. WHAT IS KNOWN ALREADY: Salpingectomy may reduce ovarian cancer incidence, although the lag-time between intervention and therapeutic effect remains to be elucidated. STUDY DESIGN, SIZE, DURATION: This nationwide population-based database study uses the Dutch pathology database to identify all women who underwent salpingectomy for ectopic pregnancy or hydrosalpinx between January 1990 and December 2012 and compared ovarian cancer incidence to a control group of women who had a benign dermal nevus removed, matched for age at the time and year of procedure. PARTICIPANTS/MATERIALS, SETTING, METHODS: After selection and manual control of intervention and control group, ovarian cancer incidence was recorded. Hazard ratios (HRs) with 95% CI for the development of ovarian cancer were calculated with Cox regression analyses, both unadjusted and adjusted for age. Subgroup analyses were performed to investigate lag-time between intervention and protective effect. MAIN RESULTS AND THE ROLE OF CHANCE: In all, 18 961 women were included in the intervention group; 17 106 women had a unilateral salpingectomy and 1855 had a bilateral salpingectomy. The control group consisted of 23 686 women. With 14 ovarian cancer cases in the intervention group, the incidence rate (IR) of ovarian cancer was 5.4 (95% CI 3.1-8.9) per 100 000 person-years. In the control group, there were 24 ovarian cancer cases, resulting in an IR of 7.1 (95% CI 4.7-10.5) per 100 000 person-years (P = 0.34). The age-adjusted HR for ovarian cancer was 0.76 (95% CI 0.39-1.47) after salpingectomy. Unilateral salpingectomy resulted in an age-adjusted HR of 0.81 (95% CI 0.41-1.59) and bilateral salpingectomy resulted in an age-adjusted HR of 0.43 (95% CI 0.06-3.16) based on one case. None of our subgroup analysis for lag-time resulted in a significant difference in ovarian cancer incidence between intervention and control group. The difference in ovarian cancer incidence appeared largest in women with at least 8 years of follow-up (P = 0.08). LIMITATIONS, REASONS FOR CAUTION: Due to the young population, ovarian cancer incidence is low, even at the end of follow-up. Furthermore, due to the anonymous nature of the pathology registry, we were unable to adjust for confounding factors. WIDER IMPLICATIONS OF THE FINDINGS: Although results did not reach statistical significance, they add to the available data on ovarian cancer incidence after salpingectomy. Our subgroup analysis suggests there may be no benefit in the first years following salpingectomy. STUDY FUNDING/COMPETING INTEREST(S): None. TRIAL REGISTRATION NUMBER: N/A.

RESUMEN

BACKGROUND: Cervical cancer is caused by Human Papilloma viruses (HPV) and is preceded by precursor stages: Cervical Intraepithelial Neoplasia (CIN). CIN is mostly found in women in their reproductive age and treated with a Loop Electrosurgical Excision Procedure (LEEP). The recurrence or residual disease rate after treatment is up to 17%. These women have a lifelong increased risk of recurrent CIN, cervical cancer and other HPV related malignancies. Furthermore, LEEP treatments are associated with complications such as premature birth. Limited data show that prophylactic HPV vaccination at the time of LEEP reduces recurrence rates, therefore leading to a reduction in repeated surgical interventions and side effect like preterm birth. The primary study objective is to evaluate the efficacy of the nonavalent HPV vaccination in women with a CIN II-III (high-grade squamous intraepithelial lesion (HSIL) lesion who will undergo a LEEP in preventing recurrent CIN II-III after 24 months. METHODS: This study is a randomised, double blinded, placebo controlled trial in 750 patients without prior HPV vaccination or prior treatment for CIN and with histologically proven CIN II-III (independent of their hrHPV status) for whom a LEEP is planned. Included patients will be randomised to receive either three injections with nonavalent (9 HPV types) HPV vaccine or placebo injections (NaCL 0.9%) as a comparator. Treatment and follow-up will be according the current Dutch guidelines. Primary outcome is recurrence of a CIN II or CIN III lesion at 24 months. A normal PAP smear with negative hrHPV test serves as surrogate for absence of CIN. At the start and throughout the study HPV typing, quality of life and cost effectiveness will be tested. DISCUSSION: Although prophylactic HPV vaccines are highly effective, little is known about the effectivity of HPV vaccines on women with CIN. Multiple LEEP treatments are associated with complications. We would like to evaluate the efficacy of HPV vaccination in addition to LEEP treatment to prevent residual or recurrent cervical dysplasia and decrease risks of repeated surgical treatment. TRIAL REGISTRATION: Medical Ethical Committee approval number: NL66775.078.18. Affiliation: Erasmus Medical Centre. Dutch trial register: NL 7938. Date of registration 2019-08-05.

RESUMEN

OBJECTIVES: METHODS: This is a retrospective study of surgically managed endometrial cancer patients in the Royal Cornwall Hospital Truro between January 2006 and August 2017. Patient characteristics, overall survival, recurrence free survival and intra- and postoperative outcomes were evaluated across socioeconomic deprivation groups in which socioeconomic deprivation was measured with the English Indices of Multiple Deprivation (IMD). RESULTS: In total, we identified 831 women, of which 690 were included. The median age was 66 years with a median BMI of 31 and the majority of tumours were endometrioid tumours (80.1%). For type 1 (endometrioid) tumours, better survival was seen in the least deprived patients, however this was not significant in a multivariate analysis and only age, stage and BMI remained significant. For type 2 (all other) tumours, no association between survival and socioeconomic deprivation was found and only stage was significant. However, more affluent patients had significantly higher recurrence rates. In addition, we did not find evidence of an association between intra- or post-operative complication rates and socioeconomic deprivation. CONCLUSION: Socioeconomic deprivation is associated with survival in endometrial cancer patients, however after adjusting for confounders this association does not remain. Only age, stage and BMI are independent prognostic factors for survival. In addition, there is no evidence of association between socioeconomic deprivation and peri-operative outcomes in endometrial cancer patients.

RESUMEN

INTRODUCTION: There is currently no standard of care for women with cervical cancer stage IB2 (FIGO 2018, ≥2 cm and <4 cm in greatest dimension) who wish to preserve their fertility. Generally, two approaches are offered. Option 1: neoadjuvant platinum-based chemotherapy (NACT) to reduce the tumor size to ≤ 2 cm, followed by Vaginal Radical Trachelectomy (VRT) with Pelvic Lymph Node Dissection (PLND) either before chemotherapy or at the time of VRT. Option 2: Abdominal Radical Trachelectomy (ART) with PLND. OBJECTIVE: To compare rates of fertility, pregnancy, life births as well as recurrence for women with cervical cancer stage IB2 treated with either NACT followed by VRT, or ART. METHODS: A systematic review was performed using the PubMed database. Articles reporting the search term 'trachelectomy' as text word or as Medical Subject Headings (MeSH) were identified. RESULTS: Ten studies were identified with a total of 338 patients. After NACT followed by VRT 39% of the women tried to conceive, 70% of these women got pregnant, of which 63% resulted in a life birth. The overall recurrence and death rate were 10% and 2.9% respectively. After ART 40% of the women tried to conceive, 21% of these women got pregnant, which resulted in a life birth rate of 42%. Recurrence and death rate after ART were 6.9%, and 3.4% respectively. CONCLUSION: Women with cervical cancer stage IB2 and a wish to preserve fertility treated with NACT followed by VRT have a significantly higher chance of pregnancy than women treated with ART, with comparative oncological results.

RESUMEN

PURPOSE: The primary objectives in this review were to (1) assess the association between socioeconomic deprivation and survival in endometrial cancer patients (2) investigate if there is an association between socioeconomic deprivation and peri-operative morbidity in endometrial cancer patients. METHODS: We performed a systematic review using Medline (1946-2018), Embase (1980-2018), Cinahl (1981-2018) and the Cochrane Controlled Register of Trials to identify studies that reported on the association between socioeconomic deprivation and survival or peri-operative outcomes in endometrial cancer patients. Included were adult women (age ≥ 18 years) diagnosed with primary endometrial cancer. Two reviewers independently selected studies and assessed bias using the Newcastle-Ottawa assessment scale. Data extraction was completed using pre-determined forms, and summary tables of evidences from the included studies were created. RESULTS: Nine studies were included in this review with a total number of 369,900 patients. Eight studies investigated survival and socioeconomic deprivation, and the majority showed that socioeconomic deprivation is associated with poorer survival in endometrial cancer patients. One study assessed the association between deprivation and peri-operative morbidity and found no difference in 30-day postoperative mortality. CONCLUSIONS: Socioeconomic deprivation seems to be associated with worse survival in endometrial cancer patients, even after adjusting for stage at diagnosis. However, the impacts of important confounders such as BMI, smoking and comorbidities are unclear and should be assessed. The relationship between socioeconomic deprivation and peri-operative morbidity is unclear, and further research is needed to evaluate this aspect. A standardised measure for socioeconomic deprivation is needed in order to establish adequate comparison between studies.

RESUMEN

INTRODUCTION: The care for patients with epithelial ovarian cancer(EOC) is organised in eight different geographical regions in the Netherlands. This situation allows us to study differences in practice patterns and outcomes between geographical regions for patients with FIGO stage IIIC and IV. METHODS: We identified all EOC patients who were diagnosed with FIGO stage IIIC or IV between 01.01.2008 and 31.12.2015 from the Netherlands Cancer Registry. Descriptive statistics were used to summarize treatment and treatment sequence(primary cytoreductive surgery(PCS) or neoadjuvant chemotherapy and interval cytoreductive surgery(NACT-ICS)). Moreover, outcome of surgery was compared between geographical regions. Multilevel logistic regression was used to assess whether existing variation is explained by geographical region and case-mix factors. RESULTS: Overall, 6,741 patients were diagnosed with FIGO IIIC or IV disease. There were no differences in the percentage of patients that received any form of treatment between the geographical regions(range 80-86%, P = 0.162). In patients that received cytoreductive surgery and chemotherapy, a significant variation between the geographical regions was observed in the use of PCS and NACT-ICS(PCS: 24-48%, P < 0.001). The percentage of complete cytoreductive surgeries after PCS ranged from 10 to 59%(P < 0.001) and after NACT-ICS from 37 to 70%(P < 0.001). Moreover, geographical region was independently associated with the outcome of surgery, also when adjusted for treatment sequence(P < 0.001). CONCLUSION: We observed a significant variation in treatment approach for advanced EOC between geographical regions in the Netherlands. Furthermore, the probability to achieve no residual disease differed significantly between regions, regardless of treatment sequence. This may suggest that surgical outcomes can be improved across geographical regions.

RESUMEN

OBJECTIVE: The Netherlands converted to high-risk (hr)HPV-based screening in 2017. An increase in referral of hrHPV-positive women with low risk for cervical intraepithelial neoplasia grade 3 or more (CIN3+) is anticipated and reduction of unjustified referrals will have priority. The relevance of koilocytosis in relation to the underlying risk of high-grade CIN in a primary HPV screening setting is unclear. The aim was to investigate whether the risk for CIN3+ differs between hrHPV-positive atypical squamous cells of undetermined significance (ASC-US)/low-grade squamous intraepithelial lesion (LSIL) with or without koilocytosis. METHODS: Retrospective cohort study, using data from the Dutch national pathology database (PALGA). The population was 1201 hrHPV-positive women with cytological diagnosis of ASC-US/LSIL. Reporting of koilocytosis was assessed as well as detection rates of CIN1 or less, CIN2 and CIN3+ for ASC-US/LSIL cytology stratified by presence or absence of koilocytosis. Crude and adjusted odds ratios were determined. RESULTS: Koilocytosis was present in 40.1% of ASC-US and 45.9% of LSIL cases. CIN3+ is significantly less often found when koilocytosis is present (7.8% for hrHPV-positive ASC-US with- vs 15.8% without koilocytosis). For hrHPV-positive LSIL this was 11.7% vs 20.2%. The crude and adjusted odds ratios for CIN3+ was 0.45 for hrHPV-positive ASC-US and 0.52 for hrHPV-positive LSIL. CONCLUSIONS: The presence of koilocytosis is a negative predictor of CIN3+. The risk of hrHPV-positive ASC-US with koilocytosis is in the same range as hrHPV-positive/cytology negative cases and in a setting of primary hrHPV screening these cases could be followed conservatively by repeat cytology. The results should be confirmed by the first data from the Dutch HPV-based screening programme.

RESUMEN

In 2017 the cervical cancer screening program in The Netherlands will be revised. Cervical smears will primarily be tested for the presence of high-risk human papillomavirus (hrHPV) instead of cytology, and vaginal self-sampling will be offered to non-responders. This includes a potential risk that part of the women who would otherwise opt for a cervical smear will wait for self-sampling. However, self-sampling for hrHPV in a responder population has never been studied yet. The aim of this study was to investigate the applicability and accuracy of self-sampling in detecting hrHPV in a screening responder population. A total of 2049 women, aged 30-60years, participating in the screening program in The Netherlands were included from April 2013 to May 2015. After they had their cervical smear taken, women self-collected a cervicovaginal sample with a brush-based device, the Evalyn Brush. Both the cervical smear and self-sample specimen were tested with the COBAS 4800 HPV platform. The hrHPV prevalence was 8.0% (95% CI 6.9-9.2) among the physician-taken samples, and 10.0% (95% CI 8.7-11.3) among the self-samples. There was 96.8% (95% CI 96.0-97.5) concordance of hrHPV prevalence between self-samples and physician-taken samples. Women in our study evaluated self-sampling as convenient (97.1%), user-friendly (98.5%), and 62.8% preferred self-sampling over a physician-taken sampling for the next screening round. In conclusion, self-sampling showed high concordance with physician-taken sampling for hrHPV detection in a responder screening population and highly acceptable to women. Implementation of HPV-self-sampling for the responder population as a primary screening tool may be considered.

RESUMEN

OBJECTIVE: To assess the impact of body mass index (BMI) on radiotherapy toxicities in endometrial cancer patients. METHODS: This was a retrospective cohort study of women diagnosed with endometrial cancer between January 2006 and December 2014 at the Royal Cornwall Hospital Trust. Women who received radiotherapy as part of their treatment, including external beam radiotherapy (EBRT) and/or vaginal brachytherapy were included. Radiation-related toxicities were graded according to the Radiation Therapy Oncology Group (RTOG) guidelines. Toxicity outcomes were compared across BMI groups-non-obese (BMI <30 kg/m2) and obese (BMI ≥30 kg/m2)-according to radiotherapy treatment received (EBRT, brachytherapy or a combination). RESULTS: Of a total of 159 women who received radiotherapy, 110 were eligible for inclusion in the study. Sixty-three women had a BMI <30 kg/m2 and 47 women were obese. Obese women had poorer Eastern Cooperative Oncology Group performance status (P = 0.021) and more comorbidities (P < 0.001) compared to the non-obese group. Total (any) toxicity rates were 60.3, 72.7 and 52.0% for EBRT and brachytherapy (N = 63), single-mode EBRT (N = 22) and brachytherapy (N = 25), respectively. BMI was not associated with the incidence of acute and late radiation toxicities in the different radiotherapy groups, and there were no differences in individual complications between the BMI groups. CONCLUSION: When comparing obese to non-obese women, obesity does not negatively impact the incidence of radiation toxicities in endometrial cancer. However, toxicities remain an important challenge as they are common and negatively influence the quality of life (QoL) of survivors. Future studies need to further explore the role of BMI and possible interventions to improve toxicities and QoL.

RESUMEN

The consensus statements regarding first-line therapies in women with ovarian cancer, reached at the Fifth Ovarian Cancer Consensus Conference held in Tokyo, Japan, in November 2015 are reported. Three topics were reviewed and the following statements are recommended: (i) Surgery: the subgroups that should be considered in first-line ovarian cancer clinical trials should be (a) patients undergoing primary debulking surgery and (b) patients receiving neo-adjuvant chemotherapy. The amount of residual disease following surgery should further stratify patients into those with absent gross residual disease and others. (ii) Control arms for chemotherapy: for advanced stage ovarian cancer the standard is intravenous 3-weekly carboplatin and paclitaxel. Acceptable alternatives, which should be stratified variables in trials when more than one regimen is offered, include weekly paclitaxel plus 3-weekly carboplatin, the addition of bevacizumab to 3-weekly carboplatin and paclitaxel, and intraperitoneal therapy. (iii) Trial Endpoints: overall survival is the preferred primary endpoint for first-line clinical trials with or without a maintenance component. Progression-free survival (PFS) is an alternative primary endpoint, but if PFS is chosen overall survival must be measured as a secondary endpoint and PFS must be supported by additional endpoints, including predefined patient reported outcomes and time to first or second subsequent therapy. For neoadjuvant therapy, additional 'window of opportunity' endpoints should be included.

RESUMEN

OBJECTIVE: To evaluate the effect of body mass index on the surgical outcomes in ovarian cancer patients. In addition, we performed a systematic review to compare our outcomes with the current literature. DESIGN: Retrospective cohort study and a systematic review of the literature. SETTING: Gynaecology department at the Royal Cornwall Hospital Trust. POPULATION: Surgically managed stage I-IV ovarian cancer patients between September 2006 and September 2014. METHODS: Primary and secondary outcome measures were evaluated across BMI categories; BMI <25 kg/m², BMI 25­29.9 kg/m², BMI ≥30 kg/m² and BMI ≥40 kg/m². A systematic review was performed according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. MAIN OUTCOME MEASURES: The primary outcome measure was surgical complications. Secondary outcome measures were other intra- and postoperative outcomes. RESULTS: Two hundred twenty-eight women were included in the study, of which 84 had a BMI <25 kg/m², 84 women had a BMI 25­29.9 kg/m², and 60 women were obese (BMI ≥30 kg/m²), 13 of whom were morbidly obese. Morbid obesity was associated with increased rates of wound complications. However, BMI did not show an association with other outcomes. In the review, an increasing BMI was associated with increased rates of wound complications and prolonged hospital stay, but did not impact other surgical outcomes. CONCLUSION: Obesity is associated with increased rates of wound complications and a prolonged hospital stay, but does not appear to affect other operative outcomes including cytoreduction status and 30-day mortality. Therefore, operative management and postoperative care require a multifactorial approach to minimise adverse outcomes.

RESUMEN

BACKGROUND: Studies of see-and-treat management of cervical intraepithelial neoplasia (CIN) vary in their inclusion criteria, resulting in a broad range of overtreatment rates. OBJECTIVES: To determine overtreatment rates in see-and-treat management of women referred for colposcopy because of suspected CIN, in order to define circumstances supporting see-and-treat management. SEARCH STRATEGY: MEDLINE, EMBASE, and the Cochrane Library were searched from inception up to 12 May 2014. SELECTION CRITERIA: Studies of see-and-treat management in women with a reported cervical smear result, colposcopic impression, and histology result were included. DATA COLLECTION AND ANALYSIS: Methodological quality was assessed with the Newcastle-Ottawa scale. We used the inverse variance method for pooling incidences, and a random-effects model was used to account for heterogeneity between studies. Overtreatment was defined as treatment in patients with no CIN or CIN1. MAIN RESULTS: Thirteen studies (n = 4611) were included. The overall overtreatment rate in women with a high-grade cervical smear and a high-grade colposcopic impression was 11.6% (95% CI 7.8-15.3%). The overtreatment rate in women with a high-grade cervical smear and low-grade colposcopic impression was 29.3% (95% CI 16.7-41.9%), and in the case of a low-grade smear and high-grade colposcopic impression it was 46.4% (95% CI 15.7-77.1%). In women with a low-grade smear and low-grade colposcopic impression, the overtreatment rate was 72.9% (95% CI 68.1-77.7%). AUTHOR'S CONCLUSIONS: The pooled overtreatment rate in women with a high-grade smear and high-grade colposcopic impression is at least comparable with the two-step procedure, which supports the use of see-and-treat management in this subgroup of women. TWEETABLE ABSTRACT: See-and-treat management is justified in the case of a high-grade smear and a high-grade colposcopic impression.

RESUMEN

BACKGROUND: Primary high-risk human papillomavirus (hrHPV) testing in cervical cancer screening shows relatively low specificity, which makes triage testing necessary. In this study, DNA methylation analysis was compared with cytology for triage testing in hrHPV-positive women. Moreover, feasibility of DNA methylation analysis directly on brush-based self-sampled specimens was assessed. METHODS: Non-responding women from population-based screening were invited to self-collect a cervico-vaginal specimen for hrHPV testing; hrHPV-positive women were referred to a physician for triage liquid-based cytology. DNA methylation analysis was performed on 128 hrHPV-positive physician-collected triage samples and 50 matched brush self-samples with QMSP for C13ORF18, EPB41L3, JAM3 and TERT. RESULTS: In physician-taken triage material, DNA methylation analysis of JAM3 showed the highest combined specificity (88%) and sensitivity (82%) for detection of CIN3+, whereas cytology showed a specificity of 48% and a sensitivity of 91%. Out of 39 women with abnormal cytology and normal histology (false-positive by cytology), 87% were negative for JAM3 and 90% for C13ORF18 methylation. Agreement between DNA methylation analysis performed directly on the matched self-sampled material and physician-taken samples was 88% for JAM3 (κ=0.75, P<0.001) and 90% for C13ORF18 (κ=0.77; P<0.001). CONCLUSIONS: DNA methylation analysis as a triage test in hrHPV-positive women is an attractive alternative to cytology. Furthermore, DNA methylation is feasible directly on brush-based self-samplers and showed good correlation with matched physician-taken samples. Direct molecular triage on self-collected specimens could optimise the screening program, especially for non-responders, as this would eliminate the need for an additional physician-taken scraping for triage testing.

RESUMEN

Human papillomavirus (HPV) is a necessary factor in the development of cervical intraepithelial neoplasia and cervical cancer. However, HPV is also a very common sexually transmitted virus and many women clear their infection. To study HPV incidence and clearance, 2,065 women, aged 18-29 years, were followed for 12 months and were asked to provide a self-collected cervico-vaginal sample and fill-out a questionnaire every 3 months. For HPV DNA detection, the SPF10 -DEIA LiPA25 system was used. Incidence rates of any-type high-risk HPV and low-risk HPV were 17.0 per 1,000-person months, and 14.3 per 1,000-person months, respectively. HPV types 16, 52, 51 and 31 had the highest type-specific incidence rates. HPV incidence was increased in singles, and women having a new relationship. A higher number of lifetime sex partners, and a higher frequency of sexual contacts in the past 3 months was associated with an increased HPV incidence. The overall clearance of the newly detected type-specific high-risk HPV infections and low-risk HPV infections was 61.2% and 69.0%, respectively. Having a sexual relationship compared to being single, and a higher sexual age both positively influenced the clearance of any-type high-risk HPV. Among the women infected with HPV 16, the women who had a co-infection had a lower proportion of clearance of HPV 16. In conclusion, in this young Dutch study population, HPV incidence rates are not related to age and comparable to other western countries. Clearance was only independently related to factors associated with sexual behavior, either past or current.

RESUMEN

PURPOSE: To investigate the effect of implementation of the HPV vaccine on HPV knowledge and HPV vaccine acceptance. METHODS: From June until December 2009 in Nijmegen, the Netherlands, 698 male and female students aged 18-25 years were recruited and interviewed about HPV, cervical carcinoma and HPV vaccine acceptance. RESULTS: Of all participants 46.6% had never heard of HPV. Women and students from the medical faculty were significantly more aware of HPV. Acceptance of a "catch-up" HPV vaccination in women was 51% and in men 27%. Acceptance of the HPV vaccination for 12-year old girls was 79%. CONCLUSION: After implementation of the HPV vaccine in the national vaccination program, > 50% of the students lack knowledge on HPV. Acceptance of a "catch-up" HPV vaccination was low. However, the acceptance of HPV vaccination for 12-year-old girls was high. Vaccine implementation strategies, focusing on 12-16 year old girls, might have caused this difference. Young adults need to be informed that the HPV vaccine may still be efficient when they are sexually active, but HPV 16 and 18 negative.

RESUMEN

OBJECTIVE: We investigated whether providing targeted information on an individual level by mail and by phone reduces anxiety in women referred to the colposcopy clinic. DESIGN: Randomised controlled trial. POPULATION: Women referred to the colposcopy clinic. METHODS: Between December 2007 and April 2010, 169 patients with abnormal smear results were randomised into two study arms. Group A received individually targeted information about the diagnosis and procedure by mail and phone. Group B received the standard folder about colposcopies alone. Patients were requested to fill out a questionnaire prior to their first colposcopy appointment. MAIN OUTCOME MEASURES: The questionnaire included the hospital anxiety and depression scale (HADS), and the Spielberger state-trait anxiety inventory (STAI), as well as a short self-administered questionnaire. RESULTS: Twenty women were excluded from further analyses after randomisation, leaving 149 women for evaluation. The median STAI state anxiety score was high (50.0), but there was no significant difference in median STAI state anxiety and HADS anxiety scores between both groups. However, knowledge about human papillomavirus and the colposcopy procedure did significantly increase in group A (P = 0.004). CONCLUSIONS: Anxiety levels before primary colposcopy are surprisingly high, and are not reduced following individually targeted information given before colposcopy.
