RESUMEN

OBJECTIVE: To evaluate if daily oral 75 µg of Desogestrel (DSG) for 3 months prior to the insertion of etonogestrel-releasing contraceptive implant (ENG-IMPLANT) might help reduce its premature discontinuation. RESULTS: A total of 66 women were randomized in the ENG-IMPLANT group (26) and in the DSG + ENG-IMPLANT group (40), respectively, in the Geneva University Hospitals and Basel University Hospital, from August 15th, 2016 through September 30th, 2019. In the DSG + ENG-IMPLANT group, patients were given a 3 months' supply of 75 µg of DSG before the insertion of the ENG-IMPLANT. All women were seen after 3 months for bleeding and satisfaction evaluation, and at 12 months post ENG-IMPLANT insertion. Higher levels of satisfaction at 12-months were found in the ENG-IMPLANT group compared to the DSG + ENG-IMPLANT group (8.5 ± 1.7 vs. 6.6 ± 2.9, p = 0.012). There were no statistically significant differences regarding tolerance (7.8 ± 2.5 vs 6.8 ± 2.6, p = 0.191) and contraceptive continuation (80% vs 72.4%, p = 0.544) between groups. CONCLUSION: DSG prior to insertion of the ENG-IMPLANT did not improve its continuation rate neither its satisfaction at 1 year. Trial registration NCT05174195. Retrospectively registered, the 30th December 2021.

RESUMEN

BACKGROUND: In low-resource countries, interpretation of the transformation zone (TZ) using the classification of the International Federation for Cervical Pathology and Colposcopy (IFCPC), adopted by the World Health Organization, is critical for determining if visual inspection with acetic acid (VIA) screening and thermal ablation treatment are possible. We aim to assess inter- and intra-observer agreement in TZ interpretation. METHODS: We performed a prospective multi-observer reliability study. One hundred cervical digital images of Human papillomavirus positive women (30-49 years) were consecutively selected from a Cameroonian cervical cancer screening trial. Images of the native cervix and after VIA were obtained. The images were evaluated for the TZ type at two time points (rounds one and two) by five VIA experts from four countries (Côte d'Ivoire, Cameroon, Peru, and Zambia) according to the IFCPC classification (TZ1 = ectocervical fully visible; TZ2 = endocervical fully visible; TZ3 = not fully visible). Intra- and inter-observer agreement were measured by Fleiss' kappa. RESULTS: Overall, 37.0% of images were interpreted as TZ1, 36.4% as TZ2, and 26.6% as TZ3. Global inter-observer reliability indicated fair agreement in both rounds (kappa 0.313 and 0.288). The inter-observer agreement was moderate for TZ1 interpretation (0.460), slight for TZ2 (0.153), and fair for TZ3 (0.329). Intra-observer analysis showed fair agreement for two observers (0.356 and 0.345), moderate agreement for two other (0.562 and 0.549), and one with substantial agreement (0.728). CONCLUSION: Interpretation of the TZ using the IFCPC classification, adopted by the World Health Organization, is critical for determining if VIA screening and thermal ablation treatment are possible. However, the low inter- and intra-observer agreement suggest that the reliability of the referred classification is limited in the context of VIA. It's integration in treatment recommendations should be used with caution since TZ3 interpretation could lead to an important referral rate for further evaluation.

RESUMEN

Human papillomavirus (HPV) testing is replacing cytological screening for cervical cancer. Our aim was to assess the expected benefits and harms of different cervical screening strategies. This study is sub-analysis of a previous cost-effectiveness study with a target population of unscreened women without cervical cancer aged ≥ 25 years. A recursive decision-tree with one-year cycles was used to model the life-long natural HPV history. Markov cohort simulations were used to assess the expected outcomes from the model. The outcomes of three strategies were compared with the absence of screening: HPV-testing on self-collected vaginal samples (Self-HPV) followed by colposcopy (Self-HPV/colpo), Self-HPV and triage with cytology (Self-HPV/PAP), cytology and triage with HPV (PAP/HPV). All screening strategies resulted in reductions in cancer cases and deaths. Self-HPV strategies were associated with a lower cancer incidence and mortality life-long, not only when performed every 3 years but also when Self-HPV was performed every 5 years vs cytology every 3 years. The gain in life expectancy obtained was 82 days with Self-HPV/colpo, 81 days with Self-HPV/PAP and 75 days with PAP/HPV compared to no screening. The number of lifetime total visits was greater with PAP/HPV compared with the Self-HPV strategies (13.13 vs < 3). The number of conizations remained relatively stable with the change of screening frequency and strategy. Self-HPV may represent a reasonable balance of harms and benefits when performed every 5 years compared to cytology every 3 years. Self-HPV/PAP yielded the most efficient harm to benefit ratio when using colposcopy as a proxy for harms.

RESUMEN

OBJECTIVES: A simple system for visual inspection with acetic acid assessment, named ABCD criteria, has been developed to increase accuracy for triaging of high-risk human papillomavirus (HPV)-positive women. This study aimed to determine the accuracy of ABCD criteria for the detection of histologically confirmed cervical intraepithelial neoplasia grade two or worse (CIN2+) in HPV-positive women living in a low-resource setting. DESIGN: Prospective study of diagnostic accuracy. SETTING: Cervical cancer screening programme based on a 3T-Approach (test, triage and treat) in the Health District of Dschang, West Cameroon. PARTICIPANTS: Asymptomatic non-pregnant women aged 30-49 years were eligible to participate. Exclusion criteria included history of CIN treatment, anogenital cancer or hysterectomy. A total of 1980 women were recruited (median age, 40 years; IQR 35-45 years), of whom 361 (18.4%) were HPV-positive and 340 (94.2%) completed the trial. INTERVENTIONS: HPV-positive women underwent a pelvic examination for visual assessment of the cervix according to ABCD criteria. The criteria comprised A for acetowhiteness, B for bleeding, C for colouring and D for diameter. The ABCD criteria results were codified as positive or negative and compared with histological analysis findings (reference standards). PRIMARY OUTCOME MEASURE: Diagnostic performance of ABCD criteria for CIN2+, defined as sensitivity, specificity, negative and positive predictive values. RESULTS: ABCD criteria had a sensitivity of 77.5% (95% CI 61.3% to 88.2%), specificity of 42.0% (95% CI 36.5% to 47.7%), positive predictive value of 15.1% (95% CI 10.8% to 20.8%), and negative predictive value of 93.3% (95% CI 87.6% to 96.5%) for detection of CIN2 +lesions. Most (86.7%) of the ABCD-positive women were treated on the same day. CONCLUSIONS: ABCD criteria can be used in the context of a single-visit approach and may be the preferred triage method for management of HPV-positive women in a low-income context. TRIAL REGISTRATION NUMBER: NCT03757299.

RESUMEN

AIMS OF THE STUDY: Remote follow-up based on self-assessment plus a telephone call with a healthcare provider is a safe and reliable method for assessing the success of medical termination of pregnancy (mTOP) and can lead to an important reduction in costs. The aim of the study was to analyse its efficacy, acceptability and associated costs. METHODS: This was a retrospective comparative study analysing two follow-up protocols for home-based mTOP. A total of 201 women were included: 56 for a standard in-clinic follow-up and 145 for a remote follow-up based on self-assessment with a low-sensitivity urine pregnancy test and a questionnaire. The main outcome was the total number of outpatient consultations needed for each procedure and the associated costs (according to the Swiss tariff system); acceptability and satisfaction were assessed using questionnaires. RESULTS: Demand for home-based termination increased by 7.8% in the observation period. There was a reduction in diagnosis of retained products of conception, with a consequent decrease of follow-up consultations from 1.47 to 0.41 appointments per patient. A reduction of 38.9% in the average cost per patient (including supplementary follow-up appointments) was observed. Moreover, the remote alternative led to higher patient satisfaction (95.1% vs 55.0%) and acceptability (84.8%). The choice for long-acting reversible contraceptives was not affected by the removal of in-person consultation. CONCLUSION: A remote follow-up procedure is an acceptable and less costly alternative to hospital-based follow-up with a higher rate of acceptability and adherence by the studied population.

RESUMEN

BACKGROUND: High-risk human papillomavirus (HPV)-positive women require triage to identify those at higher risk of cervical intraepithelial neoplasia grade 2 or worse (CIN2+). We aimed to compare visual assessment of the cervix, manual cytology and automated cytology as triage tests to screen HPV-positive women, and to assess over-treatment rates after visual assessment and over-referral rates to colposcopy after cytology. METHODS: The present cross-sectional study is nested in a large prospective screening trial in Cameroon. Evaluations of the tests have been conducted individually and in combination with HPV-16/HPV-18/45 genotyping. For the evaluation of over-treatment and colposcopic over-referral, we simulated two screening scenarios: (1) one-visit scenario (test-triage-and-treatment); and (2) two-visit scenario (test-triage-and-colposcopy). RESULTS: 1582 women with a median age of 40 years (IQR 35-45) performed self-sampling for HPV testing, of which 294 (18.6%) were HPV-positive, and 12.2% had CIN2+. Sensitivities for CIN2+ detection were 77.1% for visual assessment, 80.0% for manual cytology, and 84.8% for automated cytology. Sensitivity of combined tests was higher compared with single tests. The highest sensitivity was obtained by the combination of genotyping and automated cytology (91.2%). In the one-visit scenario, the over-treatment rate was 83.9% in referred women, with a ratio of 6.2 treated women per CIN2+. In the two-visit scenario, the lowest over-referral rate would have been under manual cytology (45.0%), with a ratio of 1.8 referred women per CIN2+. Single and combined triage strategies by automated cytology gave rise to over-referral rates of 69.2% and 76.7%, respectively, and a ratio of 3.2 and 4.3 referred women per CIN2+, respectively. DISCUSSION: Triage of HPV-positive women using a combination of genotyping and automated cytology for CIN2+ detection may provide public benefits in low- and middle-income countries.

RESUMEN

Option recommended by World Health Organization (WHO) includes human papillomavirus (HPV) primary screening followed by visual inspection with acetic acid (VIA) triage. We implemented a program based on a 3T-approach (Test-Triage and Treat). Our objective was to verify the effectiveness of the program by defining a set of performance indices. A sensitization campaign was performed in Dschang (Cameroon) and women aged 30-49 years were invited to participate for screening based on the 3T-approach. Participants performed HPV self-sampling (Self-HPV), analyzed with the point-of-care Xpert HPV assay followed by VIA/VILI triage and treatment if required. Key performance indicators (KPIs) for screening, diagnosis, treatment and follow-up were defined, and achievable targets were described for which the approach is likely to be running optimally. A total of 840 women with a mean age of 39.4±5.9 years participated. The KPIs included (i) the screening rate (8.4% at 7 months, target =20% at 12 months), (ii) HPV positivity rate (19.8%, expected range 18-25%), (iii) compliance to referral to VIA/VILI and complete test (100%, target >90%), (iv) compliance to referral to thermal ablation (100%, target >90%), (v) VIA/VILI positivity rate (50.6%, expected range 45-55%), (vi) a single visit from diagnostic to treatment (79.8%, target >80%), (vii) compliance to follow-up at 1 month (96.4%, target >80%) and (viii) at 6 months (70.6%, target >80%). Program performance based on the single-visit 3T-approach corresponded to defined targets and preliminary results support adequateness of KPIs for periodic monitoring.

RESUMEN

With a challenging diagnosis, schistosomiasis is a major public health issue worldwide, particularly in low-resource countries. The presence of Schistosoma ova in the female genital tract is a common finding, which may engender considerable suffering among women of child-bearing age. We report the asymptomatic case of endocervical schistosomiasis without visible exocervical lesions in a 41-yr-old Malagasy woman with human papillomavirus-positive status detected during a cervical cancer screening campaign in Andilampanahy, Madagascar. Schistosomiasis involving only the endocervical canal is rarely reported and can be diagnosed histologically with endocervical brushing, which therefore represents a minimally invasive and well-tolerated tool for disease detection.

RESUMEN

OBJECTIVES: To identify factors influencing the long-term prognosis after surgical repair of obstetric fistula, establish a prognosis-based classification system, and examine changes in quality of life after surgery. METHODS: A retrospective study of 308 women who underwent obstetric fistula repair at Saint Jean de Dieu Hospital, Tanguiéta, Benin, between 2008 and 2016, and were supported by a multidisciplinary management model. All participants were from rural areas of Burkina Faso. The women completed interviews before, immediately after, and 2, 4-6, and 12 months after surgery to assess their clinical state and socioeconomic and psychologic status. RESULTS: Overall, the fistulae of 230/274 (83.9%) women were considered to be repaired after 12 months. Factors associated with poor repair outcome included the presence of sclerotic tissue (odds ratio [OR], 0.25; 95% confidence interval [CI], 0.11-0.53) and intraoperative complications (OR, 0.16; 95% CI, 0.07-0.39). Women with successful surgery had a better quality of life as compared with women with an unrepaired fistula (Ditrovie score, 1.1 vs 3.9; P<0.001). CONCLUSION: The multidisciplinary Tanguiéta model for management of obstetric fistula allowed successful fistula closure, thereby facilitating the women's long-term social reintegration, and improved quality of life.

RESUMEN

OBJECTIVE: To assess triage compliance and the effect of the time from screening to triage on follow-up among HPV-positive women. METHODS: We recruited 1232 women in a screening campaign in Madagascar from February to October 2015. In the first period (February-May), HPV tests were performed remotely using the cobas test. In the second period (May-October), testing was performed on-site using the Xpert HPV assay. HPV-positive women were invited for triage with visual inspection with acetic acid (VIA) and Lugol's iodine (VILI). Systematic biopsy and endocervical brushing were performed on all HPV-positive women for quality control. Three groups were defined according to time from HPV testing to triage invitation for HPV-positive women-Group I: delayed (> 3 months), Group II: prompt (24-48 hours), and Group III: immediate (< 24 hours). RESULTS: A total 1232 self-sampled HPV tests were performed in the study period (496 in Group I, 512 in Group II, and 224 in Group III). Participants' mean age was 43.2 ± 9.3 years. Mean time from screening to VIA/VILI testing was 103.5 ± 43.6 days. Overall HPV prevalence was 28.0%. HPV prevalence was 27.2% in Group I (cobas test), 29.2% in Group 2 (Xpert test), and 26,7% in Group III (Xpert test). The VIA/VILI compliance rate was 77.8% for Group I, 82.7% for Group II, and 95.0% for Group III. Of women undergoing VIA/VILI, 56.3% in Group I and 43.5% in Groups II/III had positive results. Prevalence of cervical intraepithelial neoplasia grade 2 or worse among HPV-positive women was 9.8% for Group I and 6.8% for Groups II/III. Non-adherence was higher among rural women, uneducated women, and women in Group I. CONCLUSION: HPV-positive women with immediate VIA/VILI triage invitation had the best triage compliance. A single-day test and triage strategy is preferred for low-resource settings.

RESUMEN

BACKGROUND: Women undergoing pelvic examination for cervical cancer screening can experience periprocedural anxiety. OBJECTIVE: The aim of this study was to assess the anxiety level experienced by women undergoing a visual inspection with acetic acid and Lugol iodine (VIA and VILI) examination, with or without watching the procedure on a digital screen. METHODS: This prospective randomized study took place in the district of Dschang, Cameroon. A previous cervical cancer screening campaign tested women aged between 30 and 49 years for human papillomavirus (HPV). HPV-positive women were invited for the 12-month follow-up control visit, including a VIA/VILI examination. During that visit, we recruited women to participate in this study. Before the examination, participants were randomized in a 1:1 ratio to a control group (CG) and an intervention group (IG). Women in both groups underwent a pelvic examination and were verbally informed about the steps undertaken during the gynecological examination. The IG could also watch it live on a tablet screen. Women's anxiety was assessed before and immediately after the examination, using the Spielberger State-Trait Anxiety Inventory (STAI). A paired t test was used to compare the mean STAI score for each question before and after VIA/VILI while a nonpaired, 2-sided t test was used to compare the mean differences of the STAI score between the 2 study groups. RESULTS: A total of 122 women were randomized in the study; 4 of them were excluded as they did not undergo the pelvic examination, did not answer to the second STAI questionnaire because of personal reasons, or the cervix could not be properly visualized. Thus, the final sample size consisted of 118 patients of whom 58 women were assigned to the CG and 60 to the IG. The mean age was 39.1 (SD 5.2) years. Before the examination, the mean (SD) STAI score was 33.6 (SD 10.9) in the CG and 36.4 (SD 11.8) in the IG (P=.17). The STAI score after pelvic examination was significantly reduced for both groups (CG: 29.3 [SD 11.2]; IG: 28.5 [SD 12.0]). Overall, the difference of the STAI scores before and after the pelvic examination was lower in the CG (4.2 [SD 9.0]) than in the IG (7.9 [SD 14.3]), although the difference was not significant (P=.10). However, the women's emotional state, such as I feel secure and I feel strained, was improved in the IG as compared with the CG (CG: P=.01; IG: P=.007). CONCLUSIONS: Watching the VIA/VILI procedure in real time improved the women's emotional state but did not reduce the periprocedural anxiety measured by the STAI score. Furthermore, larger studies should assess women's satisfaction with watching their pelvic examination in real time to determine whether this tool could be included in VIA/VILI routine practice.

RESUMEN

OBJECTIVE: About 30% of women who are eligible for cervical cancer (CC) screening remain un-screened or under-screened in Switzerland. HPV testing on self-collected vaginal samples (Self-HPV) has shown to be more sensitive than cytology while also reaching non-attendees. The objective of this study was to explore the cost-effectiveness of offering Self-HPV to non-attendees in Switzerland. METHODS: A recursive decision-tree with one-year cycles was used to model the life-long natural HPV history. Markov cohort simulations were used to assess the expected outcomes from the model. The outcomes of three strategies were compared with the absence of screening: Self-HPV and triage with colposcopy (Self-HPV/colpo), Self-HPV and triage with Pap cytology (Self-HPV/PAP), cytological screening and triage with HPV (PAP/HPV). Sensitivity analyses for the key parameters of the model were conducted to check the robustness of findings. RESULTS: Offering a Self-HPV screening to non-attendees could prevent 90% of CC and 94% of CC-related deaths in the study population. The current cytology-based program could reduce by 83% the number of CC cases and by 88% the number of CC-related deaths over the population's lifetime. Compared to the absence of screening, incremental cost-effectiveness ratios (ICER) were estimated to be, per saved Quality Adjusted Life Year (QALY), 12413US$ for the strategy Self-HPV/colpo, 11138US$ for the strategy Self-HPV/Pap and 22488US$ for the strategy PAP/HPV. CONCLUSIONS: Offering Self-HPV as a CC screening strategy to non-attendees in Switzerland is a cost-effective solution that is associated with a reduction of CC cases and related deaths. Self-HPV is more cost-effective than the currently used cytology-based screening.

RESUMEN

OBJECTIVE: Persistent infection with human papillomavirus is the prerequisite for the development of cervical precancerous and cancerous lesions. The aim of this study was to determine the time-to-viral clearance in a population of human papillomavirus-infected Cameroonian women and to examine the possible predictors of viral persistence. METHODS: We conducted a prospective cohort study based on a population of human papillomavirus-positive women having previously been recruited in a self-human papillomavirus-based cervical cancer screening campaign, who were invited for a control visit at 6 and 12 months. We determined human papillomavirus clearance using self-sampling (Self-HPV) and physician-sampling (Dr-HPV), which were analyzed with a point-of-care assay (GeneXpert® IV; Cepheid, Sunnyvale, CA, USA). Logistic regression was performed to assess the relationship between sociodemographic and clinical characteristics with HPV clearance according to the two sampling techniques. RESULTS: A total of 187 participants were included in the study. At the 12 months follow-up, 79.5% (n = 104) and 65.3% (n = 86) had cleared their human papillomavirus infection according to Dr-HPV and self-HPV, respectively (p = 0.001). Only parity (>5 children) was statistically associated with viral persistence (p = 0.033). According to Dr-HPV, clearance of women treated with thermoablation at 12 months was of 84.1% versus 70.2% for non-treated women (p = 0.075). CONCLUSION: The human papillomavirus clearing rates found in our study are close to those found in other studies worldwide. Parity was significantly associated with human papillomavirus persistence. Larger, prospective studies are needed to confirm our results.

RESUMEN

OBJECTIVE: Vaginal self-sampling for human papillomavirus (HPV) testing has recently been proposed to optimize cervical cancer screening coverage. The objective of this study was to compare the performance of self-taken samples using flocked and cotton swabs for HPV detection and cellular retrieval. METHODS: We recruited women aged 21-65 years, referred to colposcopy at the Division of Gynecology of the Geneva University Hospitals between May and September 2016. Each participant collected 2 vaginal samples: 1 with a cotton swab and 1 with a flocked swab. A 1:1 randomization determined the order in which the 2 samples were taken. The swabs were introduced into a 20 mL PreservCyt® vial. Real-time polymerase chain reaction analysis using the Anyplex™ II HPV HR assay, cytofluorometric analysis and cytological cell counting were performed on each sample. RESULTS: A total of 119 participants were recruited in the study. Their mean ± standard deviation age was 35.1±8.9 years. The HPV prevalence was 29.7% and 38.1% according to the cotton and flocked swab, respectively (p=0.006). The mean number of cells collected per milliliter according to cytofluorometry was 96,726.6 with the cotton swab and 425,544.3 with the flocked swab (p<0.001). The mean number of cells detected at cytological cell count was 13,130.42 using the cotton swab and 17,503.6 using the flocked swab (p<0.001). CONCLUSION: The flocked swab achieved a greater cellular retrieval and showed an improved performance in HPV detection. Further studies are needed to assess the usability and cost-effectiveness of the 2 self-sampling devices.

RESUMEN

INTRODUCTION: Human papillomavirus (HPV) testing is a suitable tool for primary cervical cancer (CC) screening and follow-up in low-resource settings. Vaginal samples taken by women themselves (Self-HPV) are an interesting alternative to physician-performed sampling (Dr-HPV). Our aim was to assess the performance of Self-HPV and Dr-HPV at 6 and 12 months following a CC screening campaign. METHODS: This study was carried out at the Dschang District Hospital, Cameroon. Women aged 30-49 years were recruited in a CC screening campaign. HPV-positive women, of whom 2/3 were treated with thermoablation because of abnormal results at baseline screening, were invited to participate in a follow-up study. Self- and Dr-HPV, as well as cytology, were performed at 6 and 12 months. HPV samples were analyzed using the Xpert HPV assay. Sensitivity and specificity for the detection of low-grade squamous intraepithelial lesion or worse and of high-grade squamous intraepithelial lesion or worse were calculated for Self-HPV and Dr-HPV, using cytology as the reference diagnosis. RESULTS: Overall, 188 HPV-positive women were invited to attend follow-up. The obtained follow-up visits' attendance was 154 (81.9%) and 131 (69.7%) at 6 and 12 months, respectively. While the overall performance of Dr-HPV at 6 months was slightly superior, Self-HPV showed an improved sensitivity for HSIL+ detection at 12 months when compared with Dr-HPV (83.3% [95% CI 41.8-98.9] versus 71.4% [95% CI 21.5-95.8], respectively). The overall HPV positivity agreement between Self- and Dr-HPV at 6 and 12 months corresponded to a κ value of 0.62 and 0.52, respectively. Among women treated with thermoablation (n=121) at baseline screening, Self-HPV was as sensitive as Dr-HPV, although less specific (P=0.003). CONCLUSION: Self-HPV is a valuable tool for the follow-up of HPV-positive women in low-resource settings. Larger, randomized trials are needed to confirm the validity of our findings.

RESUMEN

BACKGROUND: In Madagascar, human papillomavirus (HPV), human immunodeficiency virus (HIV), and hepatitis B virus (HBV) infection, as well as syphilis share common risk factors but seem to differ in their prevalence. We measured and compared their prevalence in the country. METHODS: The data used in this study came from the Saint Damien Health Centre in Ambanja, Madagascar. The tests used for disease detection were the Alere Determine, Virucheck, rapid plasma reagin, and S-DRY self-HPV samples for HIV infection, HBV infection, syphilis, and HPV infection, respectively. RESULTS: In men and women, respectively, the prevalence was 0.6% and 0.4% for HIV infection, 2.2% and 2.0% for HBV infection, and 0.6% and 0.3% for syphilis. The HPV infection prevalence was 39.3%. CONCLUSIONS: Despite common risk factors, the prevalence of HPV infection was high, in contrast to a much lower prevalence of other sexually transmitted infections (STIs) in the same geographical area. Further investigations are required to clarify the status of STIs in the Malagasy population.

RESUMEN

INTRODUCTION: Treating cervical intraepithelial neoplasia (CIN) grades 2 and 3 is the recommended strategy for preventing invasive carcinoma in low- and middle-income countries (LMICs). Our objective was to assess the efficacy of thermoablation in the treatment of CIN2 and CIN3 in a screen-and-treat approach. METHODS: Women aged 30-49 years in Dschang, Cameroon, were invited to undergo vaginal sampling for human papillomavirus (HPV), samples being assessed by an Xpert HPV Assay. HPV-positive women underwent visual inspection with acetic acid (VIA) and visual inspection with Lugol's iodine (VILI), cervical biopsy, and endocervical curettage. Women positive for HPV-16/18/45 or other HPV types with abnormal VIA/VILI were treated by thermoablation on the same day. The primary outcome was persistence of high-grade disease on cytologic examination at 12 months. RESULTS: Of a total of 1,012 recruited women, 188 were HPV-positive, 121 patients required thermoablation, and 99 had a CIN of grade <2, making the overtreatment rate 9.9%. The cure rate for CIN2 and CIN3 at 12 months was 70.6%. Failure (higher risk of persistent disease) was associated with the presence of occult endocervical lesions at baseline diagnosis (adjusted odds ratio [aOR] =128.97 [95% confidence interval [CI], 8.80-1,890.95]; p<0.0001). First sexual intercourse before the age of 15 was also a risk factor (aOR =0.003 [95% CI, 0.001-0.61]; p=0.023). CONCLUSION: In LMICs, use of thermoablation in a screen-and-treat approach is a valuable treatment option for CIN2 and CIN3. Studies comparing thermoablation with cryotherapy are needed to determine the most appropriate treatment for cervical precancer in such countries.

RESUMEN

OBJECTIVES: To evaluate whether the endocervical brush (ECB) is better accepted by patients and health care providers for endocervical evaluation when compared to the endocervical curette (ECC), without a decrease in the quality of sampling. METHODS: Two hundred patients with cervical dysplasia were randomized at the colposcopy clinic of the University Hospital of Geneva into two groups according to technique. Patients and physicians' preference regarding the technique as well as the quality of samples were assessed. ECB samples were analyzed using both cytological (cell block) and histologic analysis, while ECC samples were analyzed using standard histologic analysis. RESULTS: Of the 200 patients, 89 were randomized to ECC, 101 to ECB and 10 were excluded due to incomplete information or cervical stenosis. Physicians preferred ECB against ECC, classifying it more frequently as an easy technique (94.1% vs.61.4%, p<0.001). Physicians more frequently evaluated the ECB as little or not uncomfortable for patients (28.7% vs.10.2%, p<0.001), though patients themselves didn't express a preference for either technique. From a quality standpoint, the brush allowed for a better quality of samples, with a lower rate of inadequate samples (2.0% vs 14.3%, p = 0.002) and greater amount of material. CONCLUSION: Endocervical sampling using ECB seems to be easier to perform and provides better quality samples. ECB can therefore be an acceptable alternative to ECC in standard practice.
