<h4>Background</h4>Cervical cancer is caused by persistent human papillomavirus (HPV) infection. US consensus management guidelines for a positive cervical screening result typically focus on the current screening result only. A negative testing history may alter risk of the following positive screening results, caused by a new HPV infection, and therefore its optimal management.<h4>Methods</h4>Women ages 30 years and older were screened with triennial HPV and cytology co-testing at Kaiser Perma ...[more]

Project description:The clinical management of cervical cancer in HIV-positive patients has challenges mainly due to the concerns on immune status. At present, their mode of management is similar to HIV-seronegative patients involving the use of chemotherapy and radiotherapy concurrently as indicated. HIV infection, cancer, radiotherapy, and chemotherapy lower immunity through reduction in CD4 cell counts. At present there are no treatment guidelines for HIV-positive patients. This study was done to systematically review the literature on cervical cancer management in HIV-positive patients and treatment outcomes. A systematic literature search was done in the major databases to identify studies on the management of HIV-positive patients with cervical cancer. Identified studies were assessed for eligibility and inclusion in the review following the guidelines of The Cochrane Handbook for Systematic Reviews and CRD's (Centre for Reviews and Dissemination) guidance for undertaking reviews in health care. Eight eligible studies were identified from the literature. Three of them were prospective while five were retrospective studies. Notably, the average age at diagnosis of cervical cancer in HIV-positive patients was a decade lower than in seronegative patients. There was no difference in distribution of stages of disease at presentation between HIV-positive and negative patients. Mild acute toxicity (Grades 1 and 2) was higher in HIV-positive patients than in HIV-negative patients in hematopoietic system. In the grades 3 and 4 reactions, anemia was reported in 4% versus 2% while gastrointestinal reactions were reported in 5% versus 2% respectively. In general, patients who were started early on HAART had higher rates of treatment completion. The study supports the suggestion that HAART should be commenced early at cervical cancer diagnosis in HIV-positive patients diagnosed with cervical cancer to ensure less toxicity and better treatment compliance.

Project description:BackgroundSeveral countries are implementing a transition to HPV testing for cervical screening in response to the introduction of HPV vaccination and evidence indicating that HPV screening is more effective than cytology. In Australia, a 2017 transition from 2-yearly conventional cytology in 18-20 to 69 years to 5-yearly primary HPV screening in 25 to 74 years will involve partial genotyping for HPV 16/18 with direct referral to colposcopy for this higher risk group. The objective of this study was to determine the optimal management of women positive for other high-risk HPV types (not 16/18) ('OHR HPV').MethodsWe used a dynamic model of HPV transmission, vaccination, natural history and cervical screening to determine the optimal management of women positive for OHR HPV. We assumed cytology triage testing was used to inform management in this group and that those with high-grade cytology would be referred to colposcopy and those with negative cytology would receive 12-month surveillance. For those with OHR HPV and low-grade cytology (considered to be a single low-grade category in Australia incorporating ASC-US and LSIL), we evaluated (1) the 20-year risk of invasive cervical cancer assuming this group are referred for 12-month follow-up vs. colposcopy, and compared this to the risk in women with low-grade cytology under the current program (i.e. an accepted benchmark risk for 12-month follow-up in Australia); (2) the population-level impact of the whole program, assuming this group are referred to 12-month surveillance vs. colposcopy; and (3) the cost-effectiveness of immediate colposcopy compared to 12-month follow-up. Evaluation was performed both for HPV-unvaccinated cohorts and cohorts offered vaccination (coverage ~72%).FindingsThe estimated 20-year risk of cervical cancer is ?1.0% at all ages if this group are referred to colposcopy vs. ?1.2% if followed-up in 12 months, both of which are lower than the ?2.6% benchmark risk in women with low-grade cytology in the current program (who are returned for 12-month follow-up). At the population level, immediate colposcopy referral provides an incremental 1-3% reduction in cervical cancer incidence and mortality compared with 12-month follow-up, but this is in the context of a predicted 24-36% reduction associated with the new HPV screening program compared to the current cytology-based program. Furthermore, immediate colposcopy substantially increases the predicted number of colposcopies, with >650 additional colposcopies required to avert each additional case of cervical cancer compared to 12-month follow-up. Compared to 12-month follow-up, immediate colposcopy has an incremental cost-effectiveness ratio (ICER) of A$104,600/LYS (95%CrI:A$100,100-109,100) in unvaccinated women and A$117,100/LYS (95%CrI:A$112,300-122,000) in cohorts offered vaccination [Indicative willingness-to-pay threshold: A$50,000/LYS].ConclusionsIn primary HPV screening programs, partial genotyping for HPV16/18 or high-grade triage cytology in OHR HPV positive women can be used to refer the highest risk group to colposcopy, but 12-month follow-up for women with OHR HPV and low-grade cytology is associated with a low risk of developing cervical cancer. Direct referral to colposcopy for this group would be associated with a substantial increase in colposcopy referrals and the associated harms, and is also cost-ineffective; thus, 12-month surveillance for women with OHR HPV and low-grade cytology provides the best balance between benefits, harms and cost-effectiveness.

Project description:ObjectiveThe aim of the study was to survey obstetrician-gynecologists' cervical cancer screening practices and management of cervical abnormalities to ascertain adherence to guidelines.MethodsFrom January to July 2019, obstetrician-gynecologists at 5 St. Louis area hospitals were surveyed online about cervical cancer screening and management practices through 13 clinical vignettes. Survey scores and the American Society of Colposcopy and Cervical Pathology (ASCCP) app use were compared using Mann-Whitney tests.ResultsWhen screening 30- to 65-year-old participants, 114 (98%) of the 116 total participants used co-testing, but only 71 (61%) screened at 5-year intervals. None used primary human papillomavirus (HPV) testing. For 21- to 29-year-old participants, 17 (15%) screened with annual cytology, whereas 14 (12%) used annual or every 3-year co-testing. Forty eight (41%) screened younger than 21 years, regardless of risk factors or only if immunocompromised. Eleven (9%) continued screening after total hysterectomy for benign indications. Only 2 (2%) responded to all clinical vignettes in adherence to guidelines. More than 30% of participants would pursue unnecessary HPV testing and/or loop electrosurgical excision procedure for persistent low-grade cytology. Fifty eight (48%) incorrectly reported hysterectomy as management for adenocarcinoma in situ on biopsy. Participants would undertreat young women with high-grade abnormalities including high-grade squamous intraepithelial lesion/cervical intraepithelial neoplasia 3 (48, 41%) and high-grade squamous intraepithelial lesion/cervical intraepithelial neoplasia 1 (65, 56%). Forty one (35%) reported exiting women from screening prematurely. The median score for participants using the ASCCP app was significantly greater than those who did not (79% vs 71%, p = .002).ConclusionsMidwestern obstetrician-gynecologists' adherence to the guidelines for cervical cancer screening and management of abnormal results is suboptimal. Although co-testing for women aged 30-65 years has been broadly adopted, primary HPV testing has not. Physicians overscreen, overtreat low-grade lesions, and undertreat high-grade lesions in young women.

Project description:BackgroundIn US cervical screening, immediate colposcopy is recommended for women with HPV-positive ASC-US (equivocal) cytology. We evaluated whether partial typing by Onclarity™ (BD) might identify HPV-positive women with low enough CIN3+ risk to permit 1-year follow-up instead.MethodsThe NCI-Kaiser Permanente Northern California Persistence and Progression cohort includes a subset of 13,890 women aged 21+ with HC2 (Qiagen)-positive ASC-US at enrollment; current median follow-up is 3.0years. Using stratified random sampling, we typed 2079 archived enrollment specimens including 329 women subsequently diagnosed with CIN3+, 563 with CIN2, and 1187 with <CIN2. Adjusting for sampling, we computed 3-year cumulative CIN3+ risks for each Onclarity typing channel, using Kaplan-Meier methods.ResultsThe 3-year CIN3+ risk for all HC2-positive women with ASC-US was 5.2%; this establishes the "benchmark" risk for colposcopic referral. Hierarchically, 3-year cumulative risks for each typing channel were 16.0% for HPV16, 7.4% for HPV18, 7.0% for HPV31, 7.1% for grouped HPV33/58, 4.3% for HPV52, 3.9% for HPV45, 2.7% for HPV51, 1.6% for HPV39/68/35, and 1.3% for HPV59/56/66.DiscussionASC-US linked to HPV16, HPV18, HPV31, or HPV33/58 warrants immediate colposcopy. Optimal management of women with HPV52 or HPV45 is uncertain. Risk of women with only HPV51, HPV39/68/35, or HPV59/56/66 might be low enough to recommend 1-year retesting permitting viral clearance. This strategy would defer colposcopy for 40% of women with HPV-positive ASC-US, half of whom would be cotest-negative at 1-year return. Approximately 10% of those with CIN3 diagnosable at enrollment would be delayed 1year instead. Cost-effectiveness analyses are needed.

Project description:Current US cervical cancer screening guidelines do not differentiate recommendations based on a woman's human papillomavirus (HPV) vaccination status. Changes to cervical cancer screening policies in HPV-vaccinated women should be evaluated. We utilized an individual-based mathematical model of HPV and cervical cancer in US women to project the health benefits, costs, and harms associated with screening strategies in women vaccinated with the bivalent, quadrivalent, or nonavalent vaccine. Strategies varied by the primary screening test, including cytology, HPV, and combined cytology and HPV "cotesting"; age of screening initiation and/or switching to a new test; and interval between routine screens. Cost-effectiveness analysis was conducted from the societal perspective to identify screening strategies that would be considered good value for money according to thresholds of $50 000 to $200 000 per quality-adjusted life-year (QALY) gained. Among women fully vaccinated with the bivalent or quadrivalent vaccine, optimal screening strategies involved either cytology or HPV testing alone every five years starting at age 25 or 30 years, with cost-effectiveness ratios ranging from $34 680 to $138 560 per QALY gained. Screening earlier or more frequently was either not cost-effective or associated with exceedingly high cost-effectiveness ratios. In women vaccinated with the nonavalent vaccine, only primary HPV testing was efficient, involving decreased frequency (ie, every 10 years) starting at either age 35 years ($40 210 per QALY) or age 30 years ($127 010 per QALY); with lower nonavalent vaccine efficacy, 10-year HPV testing starting at earlier ages of 25 or 30 years was optimal. Importantly, current US guidelines for screening were inefficient in HPV-vaccinated women. This model-based analysis suggests screening can be modified to start at later ages, occur at decreased frequency, and involve primary HPV testing in HPV-vaccinated women, providing more health benefit at lower harms and costs than current screening guidelines.

Project description:Objective:To study the clinical features of HPV58-positive cervical cancer. Methods:A retrospective analysis of 347 patients with HPV58- or HPV16 positive cervical cancer from the Department of Gynecology Tumor of Guangxi Medical University Affiliated Cancer Hospital was performed. Molecular hybridization was used to detect HPV genotypes. The clinical features, including age, pathology, and invasion, were compared between the HPV58 positive and HPV16 positive cervical cancer groups. Results:A total of 347 patients were eligible for this study, and the proportion of patients who were with poorly differentiated cancer (P?=?0.015) was significantly higher in the HPV58 positive group. HPV58 positivity was an independent risk factor for poorly differentiated cancer [HR 2.156, 95% confidence interval: 1.167-3.984, P?=?0.014]. The percentage of uterus corps invasion is significantly lower in HPV58 (p?=?0.041), but HPV58 positivity is the independent risk factor for uterus corps invasion [HR?=?3.985, 95% confidence interval: 1.066-14.893, P?=?0.040]. The overall survival of HPV58-positive cervical cancer patients with uterine corpus invasion was significantly lower (P?=?0.000). The age of patients in the HPV58-positive cervical cancer at advanced stage was significantly older (P?=?0.045). Conclusions:HPV58-positive cervical cancer patients are at higher risk of poorly differentiated cancer and uterus corps invasion. The patients with HPV58 positive cervical cancer with uterus corps invasion may result a worse prognosis.

Project description:BackgroundHPV16/18 detection may improve cervical cancer risk stratification and better guide which HPV-positive women warrant immediate colposcopy/biopsy. We estimated risks of cervical precancer and cancer by HPV genotype and cytology during the implementation phase of primary HPV testing in Norway.MethodsA total of 3111 women, aged 34-69 years, testing HPV-positive at baseline and undergoing cytology testing from February 2015 to April 2018 had data available for analysis. Risk estimates with 95% confidence intervals (95%CIs) of cervical intraepithelial neoplasia grade 3 or more severe (CIN3+) were estimated for cytology results and HPV genotypes (HPV16, HPV18, and other high-risk HPV).ResultsCIN3+ risks were higher for HPV16/18 than other high-risk HPV genotypes. Among women with any cytologic abnormality [atypical squamous cells of undetermined significance or worse], immediate risks were 57.8% (95%CI = 53.0-62.6%) for HPV16, 40.2% (95%CI = 32.3-49.2%) for HPV18, and 31.4% (95%CI = 28.7-34.3%) for other high-risk HPV. Among those with normal cytology, CIN3+ risks were 19.9% (95%CI = 15.0-26.1%) for HPV16 positives, 10.8% (95%CI = 5.6-20.5%) for HPV18 positives, and 5.5% (95%CI = 4.2-7.1%) for other high-risk HPV.ConclusionsThe benefits and harms of managing women based on HPV positivity and cytology results can be better balanced by inclusion of HPV genotyping in screening and choosing more conservative management for other high-risk HPV compared to HPV16/18.

Project description:Sudden cardiac death (SCD) is a leading cause of death among athletes, and those with a positive family history (FH) of SCD and/or cardiovascular disease (CVD) may be at increased risk. The primary objective of this study was to assess the prevalence and predictors of positive FH of SCD and CVD in athletes using four widely used preparticipation screening (PPS) systems. The secondary objective was to compare the functionality of the screening systems. In a cohort of 13,876 athletes, 1.28% had a positive FH in at least one PPS system. Multivariate logistic regression analysis identified the maximum heart rate as significantly associated with positive FH (OR = 1.042, 95% CI = 1.027-1.056, p < 0.001). The highest prevalence of positive FH was found using the PPE-4 system (1.20%), followed by FIFA, AHA, and IOC systems (1.11%, 0.89%, and 0.71%, respectively). In conclusion, the prevalence of positive FH for SCD and CVD in Czech athletes was found to be 1.28%. Furthermore, positive FH was associated with a higher maximum heart rate at the peak of the exercise test. The findings of this study revealed significant differences in detection rates between PPS protocols, so further research is needed to determine the optimal method of FH collection.

Project description:BackgroundHuman papillomavirus (HPV) testing allows women to self-collect cervico-vaginal cells at home (i.e., self-sampling). Using primary data from a randomized pilot study, we evaluated the long-term consequences and cost-effectiveness of using self-sampling to improve participation to routine cervical cancer screening in Norway.MethodsWe compared a strategy reflecting screening participation (using reminder letters) to strategies that involved mailing self-sampling device kits to women noncompliant to screening within a 5- or 10-year period under two scenarios: (A) self-sampling respondents had moderate under-screening histories, or (B) respondents to self-sampling had moderate and severe under-screening histories. Model outcomes included quality-adjusted life-years (QALY) and lifetime costs. The "most cost-effective" strategy was identified as the strategy just below $100,000 per QALY gained.ResultsMailing self-sampling device kits to all women noncompliant to screening within a 5- or 10-year period can be more effective and less costly than the current reminder letter policy; however, the optimal self-sampling strategy was dependent on the profile of self-sampling respondents. For example, "10-yearly self-sampling" is preferred ($95,500 per QALY gained) if "5-yearly self-sampling" could only attract moderate under-screeners; however, "5-yearly self-sampling" is preferred if this strategy could additionally attract severe under-screeners.ConclusionsTargeted self-sampling of noncompliers likely represents good value-for-money; however, the preferred strategy is contingent on the screening histories and compliance of respondents.ImpactThe magnitude of the health benefit and optimal self-sampling strategy is dependent on the profile and behavior of respondents. Health authorities should understand these factors prior to selecting and implementing a self-sampling policy. Cancer Epidemiol Biomarkers Prev; 26(1); 95-103. ©2016 AACR.

Project description:In 1994, a pilot program of cervical cancer screening was introduced in the Alsace region, France. Women aged 25-65 years were proposed to have one Pap smear every 3 years. The objective was to assess cervical morbidity in Alsace before the human papillomavirus vaccinated population reaches the age of screening. Data on cervical lesions and cancers were collected by EVE for the period September 2008 to August 2011 from existing medical services and cytopathology laboratories in Alsace. Cytological and histological data were completed with data from the two cancer registries covering the region (Bas-Rhin and Haut-Rhin). Cancer incidence rates were computed for the target population (truncated to 25-64 years) and were age standardized according to the world reference population. World standardized incidence rates for the whole female population were obtained from the two cancer registries. During 2008-2011, 565?153 smears were performed in 498?913 women aged 25-64 years, representing an average of 1.13 smears/woman and 1.62 smears/screened woman. The overall screening coverage was 70.1% over the 3-year period. Histologically confirmed high-grade lesions were found in 2303 women (0.5%). Moreover, 215 cervical cancers were reported among women aged 25-64 years (crude and standardized truncated incidence rate of 10.6 and 10.0/100?000 women-years, respectively). The overall screening coverage of 70% at 3 years is higher than the national rate (57%), and the overall cancer incidence of 5.5/100?000 is below the national French level. The EVE database will be useful to assess trends in cervical morbidity over time and to further assess the effect of screening as well as of human papillomavirus vaccination.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.
