[A new perspective in adolescent contraception--why prescribe an IUD first?]. / Un nouveau regard sur la contraception des adolescentes: pourquoi prescrire un dispositif intra-utérin en première intention?

Adolescent girls are very fertile and therefore need a reliable contraceptive strategy in order to prevent unwanted pregnancies. Although highly recommended by international gynecological and adolescent societies and in spite of its high efficiency, good tolerance and ease of use, only minority of adolescents use IUD as a contraceptive method. This article will focus on available IUDs suitable for adolescents and will address misconceptions and barriers to use of IUDs in this age group. We believe this information will encourage physicians in recommending IUD use to adolescents during their most vulnerable years.

HPV self-sampling as primary screening test in sub-Saharan Africa: implication for a triaging strategy.

Our objective was (i) to assess if a self-collected test for human papillomavirus (HPV) may serve as a primary cervical cancer screening method in a low-resource setting, (ii) to evaluate its implication in a screen and treat approach and (iii) to identify the most eligible age group in a screening program. Women were recruited through a cervical cancer screening campaign conducted in Cameroon. Written and oral instructions were given to participants by a health-care professional to carry out an unsupervised self-collected HPV-test (Self-HPV), followed by a physician-collected cervical sample for HPV testing (Physician-HPV) and cytology. Differences in performance between Self-HPV versus Physician-HPV and their ability to detect abnormal cytology results (ASC-US+) were evaluated. Descriptive analyses were used to examine the correlation between HPV positivity and cervical abnormalities by age. A sample of 789 women was prospectively enrolled. HPV prevalence was 14.6% and 12.7% for Self-HPV and Physician-HPV, respectively (Cohen's kappa = 0.74). HPV positivity by cytological diagnosis for ASC-US+ was similar with the two tests. positive predictive value of the Self-HPV for ASC-US+ was 20.4; odds ratio and number needed to treat were 6.5 (3.2-13.4) and 6 (4.2-10.9), respectively. We observed a trend of increasing cytological abnormalities in 30-49 year-old women and a concomitant trend of decreasing HPV prevalence supporting that this age group might be the most eligible group for screening. In conclusion, Self-HPV can be used as a primary screening test but needs to be followed by a triaging test that would identify the subset of women affected by clinically significant precancer or cancer.

Randomized comparison of vaginal self-sampling by standard vs. dry swabs for human papillomavirus testing.

BACKGROUND: To evaluate if human papillomavirus (HPV) self-sampling (Self-HPV) using a dry vaginal swab is a valid alternative for HPV testing. METHODS: Women attending colposcopy clinic were recruited to collect two consecutive Self-HPV samples: a Self-HPV using a dry swab (S-DRY) and a Self-HPV using a standard wet transport medium (S-WET). These samples were analyzed for HPV using real time PCR (Roche Cobas). Participants were randomized to determine the order of the tests. Questionnaires assessing preferences and acceptability for both tests were conducted. Subsequently, women were invited for colposcopic examination; a physician collected a cervical sample (physician-sampling) with a broom-type device and placed it into a liquid-based cytology medium. Specimens were then processed for the production of cytology slides and a Hybrid Capture HPV DNA test (Qiagen) was performed from the residual liquid. Biopsies were performed if indicated. Unweighted kappa statistics (к) and McNemar tests were used to measure the agreement among the sampling methods. RESULTS: A total of 120 women were randomized. Overall HPV prevalence was 68.7% (95% Confidence Interval (CI) 59.3-77.2) by S-WET, 54.4% (95% CI 44.8-63.9) by S-DRY and 53.8% (95% CI 43.8-63.7) by HC. Among paired samples (S-WET and S-DRY), the overall agreement was good (85.7%; 95% CI 77.8-91.6) and the κ was substantial (0.70; 95% CI 0.57-0.70). The proportion of positive type-specific HPV agreement was also good (77.3%; 95% CI 68.2-84.9). No differences in sensitivity for cervical intraepithelial neoplasia grade one (CIN1) or worse between the two Self-HPV tests were observed. Women reported the two Self-HPV tests as highly acceptable. CONCLUSION: Self-HPV using dry swab transfer does not appear to compromise specimen integrity. Further study in a large screening population is needed. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01316120.

Human papillomavirus self-sampling in Cameroon: women's uncertainties over the reliability of the method are barriers to acceptance.

OBJECTIVE: The study aimed to assess acceptability and preference for self-collected human papillomavirus tests (self-HPV) compared with traditional physician-sampled Pap tests (physician sampling) in a low-resource country. MATERIALS AND METHODS: Women were recruited through a cervical cancer screening campaign conducted in Cameroon. Written and oral instructions were given to carry out an unsupervised self-HPV, followed by a physician-collected cervical sample for HPV testing and cytology. Subsequently the women were asked to answer a questionnaire. RESULTS: A total of 243 women were prospectively enrolled in this study. Median age of participants was 39 years (range = 25-65 years). Acceptability score was higher for self-HPV (p < .001) compared with physician sampling. Preference was lower for self-HPV than physician sampling (29% vs 62%; p < .001). Most participants thought that physician sampling was more reliable than self-HPV (59% vs 1%; p < .001). Women who preferred physician sampling were significantly more likely to have low knowledge about cervical cancer and a low educational level. CONCLUSIONS: Although most of the women were more comfortable and less embarrassed with the self-HPV, they did not trust the method and did prefer physician sampling. The study underlines the need not only to educate women about HPV, cervical cancer, and its prevention but also to reassure them about the accuracy of self-HPV.

Young patients with endometrial cancer: how many could be eligible for fertility-sparing treatment?

OBJECTIVES: To assess the characteristics of young women with endometrial carcinoma, and evaluate those potentially eligible for conservative therapy. METHODS: We identified women diagnosed with endometrial cancer between 1970 and 2005 at the population-based Geneva Cancer Registry (n=1365). We classified patients into two age groups (< or =45 and >45 years old). Differences in demographic, tumor, diagnostic and treatment characteristics were tested with chi square. Kaplan-Meier analysis was used to calculate survival from endometrial cancer and the log-rank test to analyze differences in survival between the two groups. RESULTS: The young group comprised 44 (3.2%) women and the old group 1321 (96.8%) women. Synchronous ovarian malignancies were found in six patients (14%) in the young group, compared with 23 (2%) in the old group (P<0.001). Tumor stage was also different between the two groups, principally because of more stage II among the young (P=0.012). Histological tumor type, grade and specific endometrial cancer 5-year survival did not significantly differ between the two groups. According to final histopathologic evaluation, eight patients from the young group had FIGO stage IA, grade I disease, i.e. may have been eligible for fertility-sparing treatment, corresponding to an incidence rate of 0.3/100,000. CONCLUSION: No significant difference regarding tumor characteristics and survival between young and older patients was observed, except stage of disease and rate of synchronous ovarian malignancy. Conservative approach is a meaningful quality of life goal for patients with cancer, but only suitable for a limited number of patients.

User perception of endocervical sampling: A randomized comparison of endocervical evaluation with the curette vs cytobrush.

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.

Is imaging relevant for treatment choice in early stage cervical uterine cancer?

BACKGROUND: Improvement in the selection of patients with early cervical cancer eligible for different therapeutic options is expected from imaging. OBJECTIVE: We examined key tumoral features such as tumor diameter cut-off values of 2 cm or 4 cm in largest dimension, distance between tumor and internal os, outer third stromal cervical invasion, parametrial invasion and lymph node invasion. SEARCH STRATEGY: We conducted a literature search to identify all relevant studies based on imaging that evaluated these parameters. SELECTION CRITERIA: Articles were only considered when data of imaging modalities were compared with histopathological findings of the surgical specimens, considered as the gold standard. DATA COLLECTION AND ANALYSIS: We examined series that included more than 30 patients with primary untreated biopsy-confirmed cervical cancer. When numerous articles were obtained for one investigational modality, only series that included more than fifty patients were taken into account. MAIN RESULTS: Data is lacking for the diagnostic value of imaging for assessing tumor diameter cut-off values of 2 cm or 4 cm, and distance between tumor and internal os. There is a high negative predictive value of MRI for complete stromal invasion. Accurate assessment of lymph node status in patients with early cervical cancer is still lacking. PET-CT role is promising, but the diagnostic value of normal-sized hypermetabolic lymph nodes needs further investigation. CONCLUSION: Based on imaging, accurate selection of patients for treatment choice is still lacking in patients with early cervical cancer.
