RESUMO

BACKGROUND: We evaluated the longitudinal performance of three options: HPV16/18 genotyping (HPV16/18), cytology (LBC), and p16/Ki-67 dual stain cytology (DS) for the triage of high-risk Human Papillomavirus-positive (Hr-HPV+) women within the cervical screening program in Scotland. METHODS: Data were derived from a cohort of Hr-HPV+ women (n = 385) who participated in PaVDaG (Papillomavirus Dumfries and Galloway) study. Performance of triage strategies for detecting high-grade disease was assessed at 3 (in women <50 years) or 5 years (in women >50 years). Sensitivity, specificity, PPV, and cNPV of each triage test were calculated for CIN2+ and CIN3+ when used singly or sequentially. RESULTS: The sensitivity of LBC (≥ borderline), DS, and HPV 16/18 genotyping for the detection of CIN2+ was 62.7% (50.7-73.3), 77.7% (63.1-83.7), and 62.7% (50.7-73.3) with corresponding cNPVs of 10.9%, 8.4%, and 11.9%. The option with the highest sensitivity and lowest cNPV was HPV 16/18 genotyping followed by LBC of Hr-HPV other+ and then DS of the LBC negatives. This yielded sensitivity of 94.7% (86.2-98.3) and cNPV 2.7% for CIN2+. Triage performance was similar if women had tested Hr-HPV+ positive by vaginal self-sampling. CONCLUSIONS: Two-step triage with HPV 16/18 genotyping before LBC (or DS) for Hr-HPV other+ women was associated with a lower risk of significant disease at follow-up compared with single triage approaches. IMPACT: This study provides longitudinal performance data on triage strategies in Hr-HPV+ women and will be informative for the evolution of cervical screening programs that increasingly rely on molecular technologies.

RESUMO

Self-sampling provides a powerful means to engage women in cervical screening. In the original Papillomavirus Dumfries and Galloway study (PaVDaG), we demonstrated cross-sectional similarity of high-risk human papillomavirus (Hr-HPV) testing on self-taken vaginal vs clinician-taken samples for the detection of cervical intraepithelial neoplasia 2 or worse (CIN2+). Few data exist on the longitudinal performance of self-sampling; we present longitudinal outcomes of PaVDaG. Routinely screened women provided a self-taken and a clinician-collected sample. Ninety-one percent of 5136 women from the original cohort completed a further screening round. Sensitivity, specificity, positive predictive value and complement of the negative predictive value of the Hr-HPV test on self-samples for detection of CIN2+ and CIN3+ up-to 5 years after testing were determined. Additionally, clinical accuracy of Hr-HPV testing on vaginal and clinician-collected samples was assessed. A total of 183 CIN2+ and 102 CIN3+ lesions were diagnosed during follow-up. Risk of CIN2+ and CIN3+ following an Hr-HPV negative self-sample was 0.6% and 0.2%, respectively, for up to 5 years after testing. The relative sensitivity for CIN3+ and specificity for ≤CIN1 of Hr-HPV testing on self-taken specimens was slightly lower vs clinician-collected samples: 0.95 (95% CI: 0.90-0.99; PMcN = .0625) and 0.98 (95% CI: 0.95-1.00; PMcN = <.0000), respectively. The low risk of CIN2+ in women with Hr-HPV-self-sample(s) suggests, that the 3 to 5-year recall interval implemented in several cervical screening settings, based on clinician-taken samples, may be safe for self-samples. Future assessment will show if "universal" 5-year screening is appropriate for programs based on self-sampling.

RESUMO

Menopause is a major life event affecting all women in a variety of ways, both short and long term. All women should have access to accurate information, available in all forms and through all recognised sources. All healthcare professionals should have a basic understanding of the menopause and know where to signpost women for advice, support and treatment whenever appropriate. Every primary care team should have at least one nominated healthcare professional with a special interest and knowledge in menopause. All healthcare professionals with a special interest in menopause should have access to British Menopause Society Menopause Specialists for advice, support, onward referral and leadership of multidisciplinary education. With the introduction of the comprehensive British Menopause Society Principles and Practice of Menopause Care programme, the society is recognised throughout the UK as the leading provider of certificated menopause and post reproductive health education and training for healthcare professionals. Restrictions imposed by the coronavirus pandemic have been a springboard for the British Menopause Society to bring innovations to the services provided for our membership and for healthcare professionals throughout the UK.

RESUMO

Background: Several options for the triage of high-risk HPV screen-positive (hrHPV+) women were assessed.Methods: This study incorporated CIN2+ cases and controls, all of whom tested hrHPV+ and whose results of liquid-based cytology (LBC), HPV16/18 genotyping, and p16/Ki67 cytoimmunochemistry were available. Sensitivity and specificity for the CIN2+ of these triage tests were evaluated.Results: Absolute sensitivities of HPV 16/18 typing, LBC, and p16/Ki-67 cytoimmunochemistry for CIN2+ detection were 61.7%, 68.3%, and 85.0% for women with hrHPV+ clinician-taken samples. Respective specificities were 70.5%, 89.1%, and 76.7%. The absolute accuracy of the triage tests was similar for women with a hrHPV+ self-sample. P16/Ki-67 cyto-immunochemistry was significantly more sensitive than LBC although significantly less specific.Conclusions: All three single-test triage options, if positive, exceed the threshold of 20% risk at which colposcopy would be indicated. However, none of them conferred a post-test probability of CIN2+ <2%; which would permit routine recall. P16/Ki-67 cytoimmunochemistry on HPV16/18 negative women had a post-test probability of CIN2+ of 1.7% and 0.6% if also LBC negative.Impact: This is one of the few studies to directly compare the performance of triage strategies of hrHPV+ women, in isolation and combinations. It is the only study assessing triage strategies in women who test hrHPV+ in self-taken vaginal samples. A combined triage option that incorporated HPV 16/18 typing prior to p16/ki-67 cytoimmunochemistry in HPV 16/18-negative women yielded a post-test probability of CIN2+ of >20%, whereas women who tested negative had a probability of CIN2+ of <2%.

RESUMO

OBJECTIVES: Papillomavirus Dumfries and Galloway (PaVDaG) assessed the performance of a high-risk human papillomavirus (hrHPV) PCR-based assay to detect high-grade cervical intraepithelial neoplasia (CIN2+) in self-collected vaginal and urine samples. SETTING: Women attending routine cervical screening in primary care. PARTICIPANTS: 5318 women aged 20-60 years provided self-collected random urine and vaginal samples for hrHPV testing and a clinician-collected liquid-based cytology (LBC) sample for cytology and hrHPV testing. INTERVENTIONS: HrHPV testing. All samples were tested for hrHPV using the PCR-based cobas 4800 assay. Colposcopy was offered to women with high-grade or repeated borderline/low-grade cytological abnormalities; also to those who were LBC negative but hrHPV 16/18 positive. PRIMARY AND SECONDARY OUTCOME MEASURES: The self-tests' absolute sensitivity and specificity for CIN2+ were assessed on all biospecimens; also, their relative sensitivity and specificity compared with clinician-taken samples. Interlaboratory and intralaboratory performance of the hrHPV assay in self-collected samples was also established. RESULTS: HrHPV prevalence was 14.7%, 16.6% and 11.6% in cervical, vaginal and urine samples, respectively. Sensitivity for detecting CIN2+ was 97.7% (95% to 100%), 94.6% (90.7% to 98.5%) and 63.1% (54.6% to 71.7%) for cervical, vaginal and urine hrHPV detection, respectively. The corresponding specificities were 87.3% (86.4% to 88.2%), 85.4% (84.4% to 86.3%) and 89.8% (89.0% to 90.7%). There was a 38% (24% to 57%) higher HPV detection rate in vaginal self-samples from women over 50 years compared with those ≤29 years. Relative sensitivity and specificity of hrHPV positivity for the detection of CIN2+ in vaginal versus cervical samples were 0.97 (0.94 to 1.00) and 0.98 (0.97 to 0.99); urine versus cervical comparisons were 0.53 (0.42 to 0.67) and 1.03 (1.02 to 1.04). The intralaboratory and interlaboratory agreement for hrHPV positivity in self-samples was high (κ values 0.98 (0.96 to 0.99) and 0.94 (0.92 to 0.97) for vaginal samples and 0.95 (0.93 to 0.98) and 0.90 (0.87 to 0.94) for urine samples). CONCLUSIONS: The sensitivity of self-collected vaginal samples for the detection of CIN2+ was similar to that of cervical samples and justifies consideration of this sample for primary screening.

RESUMO

The menopause should be diagnosed based on age, menstrual history and clinical symptoms, and as such, follicle stimulating hormone testing may be considered inappropriate when diagnosing the menopause or peri-menopause in women aged 45 and over. As part of a demand optimisation programme, the number of follicle stimulating hormone tests requested to diagnose the menopause in this age group was quantified and educational interventions were implemented to reduce inappropriate testing. The number of follicle stimulating hormone tests requested to diagnose the menopause in women aged 45 and over was successfully and sustainably reduced.

RESUMO

The term genitourinary syndrome of menopause (GSM) emerged following a consensus conference held in May 2013. GSM is a more descriptive term than vulvovaginal atrophy (VVA) and does not imply pathology. However there are concerns that GSM is all encompassing and includes not only symptoms resulting from estrogen deficiency, but also those arising from the effects of ageing and other processes on the bladder and pelvic floor. Focusing on symptoms related to estrogen deficiency, the update provides a practical guide for health and allied health professionals on the impact of GSM on women and their partners, assessment, management and areas for future research. As GSM is a chronic condition, long term therapy is required. Hormonal, nonhormonal, laser and alternative and complementary therapies are described.

RESUMO

AIMS: To assess the performance of a clinically validated human papillomavirus (HPV) test (the Cobas 4800 HPV test) in urine and self-taken vaginal specimens within a colposcopy population and to assess HPV prevalence before and after treatment across the different biospecimens. METHODS: A total of 100 women attending a colposcopy clinic provided three biospecimens (a clinician-taken liquid-based cytology sample (LBC), a self-taken vaginal sample and a urine sample) for HPV testing. HPV prevalence and concordance was compared across the biospecimens and clinical performance relative to the detection of cervical intraepithelial neoplasia (CIN)2+ and CIN3+ was assessed. A total of 39 women retuned at 6 months for a post-treatment follow-up appointment, and HPV concordance in all biospecimens was measured relative to their original HPV status. RESULTS: 65 cases of CIN2+ were detected in the baseline population; sensitivity for CIN2+ was 92% (82 to 97) for the vaginal and the LBC sample and 80.0 (68% to 88%) for the urine sample. In the follow-up (post treatment) population, women were twice as likely to be HPV positive in their urine or vaginal sample compared with the equivalent LBC sample. CONCLUSIONS: Vaginal and LBC samples showed very similar performance for the detection of CIN2+ in this population using the Cobas HPV test; further validation of these findings in screening contexts will be of value. Self-taken samples may have less utility in a 'test of cure' setting-given the higher prevalence of HPV relative to LBC.

RESUMO

Current guidelines recommend that hormone therapy (HT) in postmenopausal women with a uterus include a progestin to protect against endometrial hyperplasia. However, many concerns relating to HT use appear to be related to the progestin component, including cardiovascular risk, breast stimulation, and irregular vaginal bleeding. Conjugated estrogens (CE) combined with the selective estrogen receptor modulator bazedoxifene (BZA) is a new progestin-free HT option for alleviating estrogen deficiency symptoms in postmenopausal women with a uterus for whom treatment with progestin-containing therapy is not appropriate. Five double-blind, randomized, placebo-controlled, phase 3 studies, known as the Selective estrogens, Menopause, And Response to Therapy (SMART) trials have investigated the efficacy of CE/BZA for relieving vasomotor symptoms (VMS), and effect on bone mass, as well as endometrial and breast safety in postmenopausal women. In a 12-week study, CE 0.45 mg/BZA 20 mg significantly reduced the number and severity of hot flushes compared with placebo at weeks 4 and 12. Unlike estrogen-progestin therapy (EPT), CE 0.45 mg/BZA 20 mg did not increase breast density compared with placebo. In clinical trials up to 2 years, CE/BZA had a favorable tolerability profile, demonstrated by amenorrhea rates similar to placebo. Vascular disorders including venous thromboembolic events (pulmonary embolism, retinal vein thrombosis, deep vein thrombosis, and thrombophlebitis) were rare events, occurring in less than 1 per 1000 patients. CE/BZA was associated with significantly higher incidences of amenorrhea and lower incidences of bleeding compared with CE/medroxyprogesterone acetate in 2 comparative trials. Therefore, CE 0.45 mg/BZA 20mg provides an effective, well-tolerated, progestin-free alternative to EPT for postmenopausal women with a uterus.
