Cervical cancer screening and management practices among providers in the National Breast and Cervical Cancer Early Detection Program (NBCCEDP)

Lifting the fog of confusion about breast cancer screening guidelines: Surprise - it's about the money!

Large amounts of misinformation denigrating the benefits of breast cancer screening have been published over the past 50 years and continue to be published. Each effort to reduce breast cancer screening has been refuted, scientifically, but the efforts continue. The motivation has been unclear until the recent guidelines issued by the American Society of Breast Surgeons who support annual screening starting at the age of 40 contrasted with the American College of Physicians who advocated delaying screening until the age of 50 and then biennially. An analysis of the facts can only lead to the conclusion that delayed screening has been chosen to save money rather than lives.

Integrating multiple community perspectives in intervention development

We offer a framework and exemplify how to integrate multiple community perspectives in research to develop breast cancer screening interventions among Latinas non-adherent to national guidelines. We leverage members of an academic institution's community consultative service [community engagement advisory board (CEAB) members]; study team members [community health workers (CHWs)] and study-eligible individuals (non-adherent Latinas). First, we asked what was needed from CEAB members (N=17), CHWs (N=14) and non-adherent Latinas (N=20) in one-time semi-structured group consultations and focus groups. Second, we drafted materials. Third, we conducted group consultations and focus groups with a new set of CEAB members (N=13), CHWs (N=17) and non-adherent Latinas (N=16) to reflect on our initial analysis and draft materials. Fourth, we finalized interventions. Certain recommendations were shared across stakeholders and simple to integrate (e.g. costs → access to free services). Some recommendations varied, but complementary integration was possible (e.g. location versus recruitment → multiple recruitment in multiple community areas). Others were distinct across stakeholders and resulted in strategies to recognize participants' agency and inform their choices about breast cancer screening (e.g. differences in preferred information about screening → personalized information and evidence about all screening options).

Factors associated with high-risk human papillomavirus test utilization and infection: a population-based study of uninsured and underinsured women

Background

Current cervical cancer screening guidelines recommend a Pap test every 3 years for women age 21–65 years, or for women 30–65 years who want to lengthen the screening interval, a combination of Pap test and high-risk human papilloma virus testing (co-testing) every 5 years. Little population-based data are available on human papilloma virus test utilization and human papilloma virus infection rates. The objective of this study was to examine the patient-level, cervical cancer screening, and area-level factors associated with human papilloma virus testing and infection among a diverse sample of uninsured and underinsured women enrolled in the New Jersey Cancer Early Education and Detection (NJCEED) Program.

Methods

We used data for a sample of 50,510 uninsured/underinsured women, age ≥ 29 years, who screened for cervical cancer through NJCEED between January 1, 2009 and December 31, 2015. Multivariable logistic regression models were used to estimate associations between ever having a human papilloma virus test or a positive test result, and individual- (age, race/ethnicity, birthplace) and area-level covariates (% below federal poverty level, % minority, % uninsured), and number of screening visits.

Results

Only 26.6% (13,440) of the sample had at least one human papilloma virus test. Among women who underwent testing, 13.3% (1792) tested positive for human papilloma virus. Most women who were positive for human papilloma virus (99.4%) had their first test as a co-test. Human papilloma virus test utilization and infection were significantly associated with age, race/ethnicity, birthplace (country), and residential area-level poverty. Rates of human papilloma virus testing and infection also differed significantly across counties in the state of New Jersey.

Conclusions

These findings suggest that despite access to no-cost cervical cancer screening for eligible women, human papilloma virus test utilization was relatively low among diverse, uninsured and underinsured women in New Jersey, and test utilization and infection were associated with individual-level and area-level factors.

Population-based cancer screening programmes in low-income and middle-income countries: regional consultation of the International Cancer Screening Network in India

The reductions in cancer morbidity and mortality afforded by population-based cancer screening programmes have led many low-income and middle-income countries to consider the implementation of national screening programmes in the public sector. Screening at the population level, when planned and organised, can greatly benefit the population, whilst disorganised screening can increase costs and reduce benefits. The International Cancer Screening Network (ICSN) was created to share lessons, experience, and evidence regarding cancer screening in countries with organised screening programmes. Organised screening programmes provide screening to an identifiable target population and use multidisciplinary delivery teams, coordinated clinical oversight committees, and regular review by a multidisciplinary evaluation board to maximise benefit to the target population. In this Series paper, we report outcomes of the first regional consultation of the ICSN held in Agartala, India (Sept 5-7, 2016), which included discussions from cancer screening programmes from Denmark, the Netherlands, USA, and Bangladesh. We outline six essential elements of population-based cancer screening programmes, and share recommendations from the meeting that policy makers might want to consider before implementation.

Recommendations on Quality Control and Quality Assurance in Cervical Cytology

OBJECTIVE

We aimed to critically evaluate the importance of quality control (QC) and quality assurance (QA) strategies in the routine work of uterine cervix cytology.

STUDY DESIGN

We revised all the main principles of QC and QA that are already being implemented worldwide and then discussed the positive aspects and limitations of these as well as proposing alternatives when pertinent.

RESULTS

A literature review was introduced after highlighting the main historical revisions, and then a critical evaluation of the principal innovations in screening programmes was conducted, with recommendations being postulated.

CONCLUSIONS

Based on the analysed data, QC and QA are two essential arms that support the quality of a screening programme.

Transition from film to digital mammography: impact for breast cancer screening through the national breast and cervical cancer early detection program

INTRODUCTION

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides mammograms and diagnostic services for low-income, uninsured women aged 40-64 years. Mammography facilities within the NBCCEDP gradually shifted from plain-film to digital mammography. The purpose of this study is to assess the impact of replacing film with digital mammography on health effects (deaths averted, life-years gained [LYG]); costs (for screening and diagnostics); and number of women reached.

METHODS

NBCCEDP 2010 data and data representative of the program's target population were used in two established microsimulation models. Models simulated observed screening behavior including different screening intervals (annual, biennial, irregular) and starting ages (40, 50 years) for white, black, and Hispanic women. Model runs were performed in 2012.

RESULTS

The models predicted 8.0-8.3 LYG per 1,000 film screens for black women, 5.9-7.5 for white women, and 4.0-4.5 for Hispanic women. For all race/ethnicity groups, digital mammography had more LYG than film mammography (2%-4%), but had higher costs (34%-35%). Assuming a fixed budget, 25%-26% fewer women could be served, resulting in 22%-24% fewer LYG if all mammograms were converted to digital. The loss in LYG could be reversed to an 8%-13% increase by only including biennial screening.

CONCLUSIONS

Digital could result in slightly more LYG than film mammography. However, with a fixed budget, fewer women may be served with fewer LYG. Changes in the program, such as only including biennial screening, will increase LYG/screen and could offset the potential decrease in LYG when shifting to digital mammography.

Quality assurance through quality improvement and professional development in the National Breast and Cervical Cancer Early Detection Program

Quality assurance (QA) is the process of providing evidence that the outcome meets the established standards. Quality improvement (QI), by contrast, is the act of methodically developing ways to meet acceptable quality standards and evaluating current processes to improve overall performance. In the case of the National Breast and Cervical Cancer Early Detection Program (NBCCEDP), the desired outcome is the delivery of quality health care services to program clients. The NBCCEDP provides professional development to ensure that participating providers have current knowledge of evidence-based clinical standards regarding breast and cervical cancer screening and diagnosis and are monitoring women with abnormal screening results for timely follow-up. To assess the quality of clinical care provided to NBCCEDP clients, performance data are collected by NBCCEDP grantees and compared against predetermined Centers for Disease Control and Prevention (CDC) benchmarks known as Data Quality Indicator Guides. In this article, the authors describe 1) the development and use of indicators for QI in the NBCCEDP and 2) the professional development activities implemented to improve clinical outcomes. QA identifies problems, whereas QI systematically corrects them. The quality of service delivery and improved patient outcomes among NBCCEDP grantees has enhanced significantly because of continuous monitoring of performance and professional development. By using QA, NBCCEDP grantees can maximize the quality of patient screening, diagnostic services, and follow-up. Examples of grantee activities to maintain quality of care are also described in this report.

Focus group discussions in community-based participatory research to inform the development of a human papillomavirus (HPV) educational intervention for Latinas in San Diego

The purpose of this paper is to demonstrate the usefulness of formative focus groups as a community-based participatory research (CBPR) method in developing cancer education programs. Two focus groups were conducted according to CBPR principles, in order to develop a community-competent human papillomavirus (HPV)/cervical cancer educational program for Latinas living in the USA/Mexico border region. Focus group participants were 18 female Mexican American community health advisors. Participants reported that there is limited information and many myths about HPV and the vaccine in the Latino/Latina community, along with many barriers to acceptance of HPV/cervical cancer-related information. Furthermore, participants discussed their recommendations for the development of a culturally appropriate HPV educational program. From these data, we have a better understanding of the HPV/cervical cancer educational approach that will be most accepted in the community and what key information needs to be provided to women who participate in the program, which reinforces the importance of the CBPR approach to the formative phase of cancer education program development.

Practice patterns in cervical cancer screening and human papillomavirus testing

The use of human papillomavirus DNA testing plus Papanicolaou (Pap) testing (cotesting) for cervical cancer screening in women 30 years and older has been recommended since 2006. However, few studies have detailed the adoption of such cotesting in clinical practice. We examined the trends in monthly percentage of Pap tests ordered as cotests in our laboratory over a 2.5-year period and used joinpoint regression to identify periods in which there was a change in the average monthly proportion of cotests. Cotesting of patients 30 years and older increased from 15.9% in January 2008 to 39.4% in June 2010. In patients aged 18 to 29 years, cotesting initially increased, but showed a downward trend in the last 14 months of the study, ending at 7.7% in June 2010. Our study highlights increased adoption of age-appropriate cotesting as well as the persistence of age-inappropriate cotesting.

Timeliness of cervical cancer diagnosis and initiation of treatment in the National Breast and Cervical Cancer Early Detection Program

OBJECTIVES

To examine time intervals from cervical cancer screening to diagnosis and treatment initiation among low-income and uninsured women in the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) during two consecutive time periods.

METHODS

We analyzed NBCCEDP data for women with abnormal Pap tests (n=100,167), from which 1,417 invasive cervical cancers were diagnosed. We examined two time intervals for this study: diagnostic interval (time from abnormal Pap test to the date of definitive diagnosis) and treatment initiation interval (time from definitive diagnosis to treatment initiation) for two time periods: 1996-2002 and 2003-2009. We compared median time intervals for diagnostic and treatment initiation using the Kruskal-Wallis test. Adjusted proportions (predicted marginals) were calculated using logistic regression to examine diagnosis and treatment within program benchmarks (≤60 days).

RESULTS

Median diagnostic intervals decreased overall by 6 days (54 vs. 48 days, p<0.001). This decrease in the median diagnostic interval was noted for all variables examined. The median treatment initiation intervals remained stable over the two time periods.

CONCLUSIONS

Women screened by the NBCCEDP receive diagnostic follow-up and initiate treatment within preestablished program guidelines.

Evaluation of HPV-16 and HPV-18 genotyping for the triage of women with high-risk HPV+ cytology-negative results

The ATHENA (Addressing THE Need for Advanced HPV Diagnostics) HPV study evaluated the clinical usefulness of the cobas HPV Test (Roche Molecular Systems, Pleasanton, CA) for high-risk human papillomavirus (HR-HPV) testing (14 HR types) and individual HPV-16/HPV-18 genotyping in women undergoing routine cervical cytology screening in the United States. For the study, 47,208 women were recruited, including 32,260 women 30 years or older with negative cytology. All women with positive results for HR-HPV (n = 4,219) plus a subset of HR-HPV- women (n = 886) were referred for colposcopy and biopsy. The overall prevalence of HR-HPV was 6.7% and of HPV-16/HPV-18 was 1.5%. Cervical intraepithelial neoplasia grade 2 (CIN 2) or worse was found in 1.2% of women examined. The estimated absolute risk of CIN 2 or worse in HPV-16+ and/or HPV-18+ women was 11.4% (95% confidence interval [CI], 8.4%-14.8%) compared with 6.1% (95% CI, 4.9%-7.2%) in HR-HPV+ and 0.8% (95% CI, 0.3%-1.5%) in HR-HPV- women. These analyses validate the 2006 American Society of Colposcopy and Cervical Pathology guidelines for HPV-16/HPV-18 genotyping, which recommend referral to colposcopy of HPV-16/HPV-18+ women with negative cytology.

Trends of human papillomavirus testing in cervical cancer screening at a large academic cytology laboratory

OBJECTIVE

To estimate time trends of actual provider use of human papillomavirus (HPV) testing in cervical cancer screening by using laboratory and administrative data from the Johns Hopkins Hospital Division of Cytopathology in Baltimore, Maryland.

METHODS

In this ecologic trend study, we analyzed 178,510 Pap specimen records and 12,221 HPV tests among 85,048 patients from 2001 to 2007. Monthly frequencies and proportions of HPV reflex testing and HPV cotesting with Pap (stratified by patient ages 30 and older and 18-29 years) were calculated. Time trends of monthly HPV testing proportions were analyzed using joinpoint regression methods.

RESULTS

From April 2002, when the American Society for Colposcopy and Cervical Pathology added HPV reflex testing to its guidelines, to December 2007, the monthly the proportion of reflex testing was 95.8%. From February 2004, when the society added HPV cotesting with Pap among women aged 30 years or older to its guidelines, to December 2007, the overall proportion HPV cotesting with Pap among patients aged 30 years or older was 7.8% (compared with 4.9% among patients 18-29 years [P<.01]). The highest proportion of HPV cotesting among women aged 30 years or older, 15%, was observed in September 2006, and the trend later plateaued around 13%. The monthly proportions of HPV reflex testing and cotesting with Pap changed significantly over time.

CONCLUSION

These data reveal that a small percentage of women aged 30 years or older received HPV cotesting with Pap, thus identifying a significant opportunity for providers to improve patient care in cervical cancer prevention.

Cancer screening practices among physicians in the national breast and cervical cancer early detection program

BACKGROUND

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides low-income, uninsured women with screening and diagnostic services for breast and cervical cancer. Our study was conducted to describe the demographic and practice characteristics of participating and nonparticipating physicians, as well as their beliefs, adoption of new screening technologies, and recommendations for breast and cervical cancer screening.

METHODS

From a 2006-2007 nationally representative survey, we identified 1,111 practicing primary care physicians who provide breast and cervical cancer screenings and assessed their recommendations using clinical vignettes related to screening initiation, frequency, and cessation. Responses of physicians participating in the NBCCEDP were compared with those from nonparticipating physicians.

RESULTS

Of the physicians surveyed, 15% reported participation in the NBCCEDP, 65% were not participants, and 20% were not sure or did not respond to this question. Program physicians were significantly more likely to practice in multispecialty settings, in a rural location, and in a hospital or clinic setting and had more patients who were female and insured by Medicaid or uninsured compared with nonprogram physicians. Beliefs about the effectiveness of screening tools or procedures in reducing breast or cervical cancer mortality were similar by program participation. Adoption of new technologies, including digital mammography and human papillomavirus (HPV) testing, and making guideline-consistent recommendations for screening initiation, frequency, and cessation did not differ significantly by program participation.

CONCLUSIONS

Although there may be differences in physician characteristics and practice settings, the beliefs and screening practices for both breast and cervical cancer are similar between program and nonprogram providers.

US physicians' intentions regarding impact of human papillomavirus vaccine on cervical cancer screening

BACKGROUND

US cervical cancer screening recommendations have not changed since the human papillomavirus (HPV) vaccine introduction in 2006, but epidemiological and cost-effectiveness studies indicate that recommendations will need to change for fully vaccinated women. We evaluated physician intentions regarding HPV vaccine's impact on future screening.

METHODS

A nationally representative sample of 1212 primary care physicians was surveyed in 2006-2007 (response rate: 67.5%). Our study included 1114 physicians who provided Pap testing. Questions covered Pap test screening practices and intentions regarding HPV vaccine's impact on screening. Distribution differences were assessed using chi(2) statistics; multivariate analyses were performed.

RESULTS

Overall, 40.7% (95% confidence interval (CI): 37.6-43.8%) of physicians agreed that the HPV vaccine will affect screening initiation, and 38.2% (35.0-41.5%) agreed that vaccination will affect screening frequency. Significant differences in responses were found by specialty; internists were more likely to agree that vaccination would impact screening than other specialties. Belief in the effectiveness of new screening technologies was associated with intention to change screening initiation (odds ratio (OR) = 1.66 (1.20-2.31)) and frequency (OR = 1.99 (1.40-2.83)). Adherence to current Pap test screening interval guidelines was associated with intention to change screening frequency (OR = 1.39 (1.01-1.91)).

CONCLUSIONS

Many providers anticipate adjusting screening for vaccinated women, but a significant group believes nothing will change or are unsure. The present study provides important baseline data on intentions in the period preceding widespread vaccine diffusion and may help explain current and future trends in practice patterns.

Association between physician specialty and uptake of new medical technologies: HPV tests in Florida Medicaid

BACKGROUND

It is well established that specialists often adopt new medical technologies earlier than generalists, and that racial and ethnic minority patients are less likely than White patients to receive many procedures and prescription drugs. However, little is known about the role that specialists or generalists may play in reducing racial and ethnic disparities in uptake of new medical technologies. Human papillomavirus (HPV) DNA tests, introduced as a cervical cancer screening tool in 2000, present a rich context for exploring patterns of use across patient and provider subgroups.

OBJECTIVE

To identify patient characteristics and the provider specialty associated with overall and appropriate use of HPV DNA tests over time, and to examine the associations between clinical guidelines and adoption of the test in an underserved population.

DESIGN

Retrospective longitudinal study using Florida Medicaid administrative claims data.

PARTICIPANTS

Cervical cancer screening test claims for 415,239 female beneficiaries ages 21 to 64 from July 2001 through June 2006.

MAIN MEASURES

Overall and appropriate use of HPV DNA tests.

KEY RESULTS

Although minority women were initially less likely than White women to receive HPV DNA tests, test use grew more rapidly among Black and Hispanic women compared to White women. Obstetricians/gynecologists were significantly more likely than primary care providers to administer HPV DNA tests. Release of the first set of clinical guidelines was associated with a large increase in the use of HPV DNA tests (adjusted odds ratio: 2.46, p<0.0001); subsequent guidelines were associated with more modest increases.

CONCLUSIONS

Uptake of new cervical cancer screening protocols can occur quickly among traditionally underserved groups and may be aided by early adoption by specialists.

Repeat pap testing and colposcopic biopsies in the underserved

OBJECTIVE

To quantify repeat Pap testing and colposcopic biopsies among women in the National Breast and Cervical Cancer Early Detection Program between 2003 and 2006 (N=955,494).

METHODS

Rates of repeat Pap testing (two tests within 9 months) and colposcopic biopsies were estimated along with 95% confidence intervals (CIs). Odds ratios and 95% CIs for receipt of colposcopic biopsy compared with repeat Pap testing were estimated from multivariable logistic regression models. Finally, we estimated positive predictive values and 95% CIs of cervical intraepithelial neoplasia (CIN) 2 or worse (CIN 3, carcinoma in situ, invasive cancer) for two strategies: 1) repeat Pap testing followed by colposcopic biopsy and 2) colposcopic biopsy alone.

RESULTS

There were 39,583 and 53,880 women with repeat Pap testing and colposcopic biopsy, respectively, from 2003 to 2006. Overall, age-standardized rates of repeat Pap testing and colposcopic biopsies were 37.2 per 1,000 women and 39.3 per 1,000 women, respectively. Younger women, Hispanic women, and African-American women were more likely to receive colposcopic biopsies compared with repeat Pap tests. Positive predictive values of colposcopic biopsy were highest after abnormal Pap test results (27% after a result of atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion, 70% after a result of high-grade squamous intraepithelial lesion/squamous cell cancer).

CONCLUSION

Colposcopic biopsies are common among young women after being screened for cervical cancer and, except among those with the most severe Pap test results, may not be efficient in detecting serious disease. These results conflict with current recommendations for less aggressive follow-up for most young women.

Timeliness of breast cancer diagnosis and initiation of treatment in the National Breast and Cervical Cancer Early Detection Program, 1996-2005

OBJECTIVES

To determine the effects of program policy changes, we examined service delivery benchmarks for breast cancer screening in the National Breast and Cervical Cancer Early Detection Program (NBCCEDP).

METHODS

We analyzed NBCCEDP data for women with abnormal mammogram or clinical breast examination (n=382 416) from which 23 701 cancers were diagnosed. We examined time to diagnosis and treatment for 2 time periods: 1996 to 2000 and 2001 to 2005. We compared median time for diagnostic, treatment initiation, and total intervals with the Kruskal-Wallis test. We calculated adjusted proportions (predicted marginals) with logistic regression to examine diagnosis and treatment within program benchmarks (<or=60 days) and time from screening to treatment (<or=120 days).

RESULTS

Median diagnostic intervals decreased by 2 days (25 vs 23; P<.001). Median treatment initiation intervals increased by 2 days (12 vs 14; P<.001). Total intervals decreased by 3 days (43 vs 40; P<.001). Women meeting the 60-day benchmark for diagnosis improved the most for women with normal mammograms and abnormal clinical breast examinations from 77% to 82%.

CONCLUSIONS

Women screened by the NBCCEDP received diagnostic follow-up and initiated treatment within preestablished program guidelines.

An evaluation of a Medicaid expansion for cancer care: The Breast and Cervical Cancer Prevention and Treatment Act of 2000

The National Breast and Cervical Cancer Early Detection Program is a multifaceted, federal program that provides breast and cervical cancer screening and diagnostic services to low-income women, but does not cover the costs of treatment. This study used a fixed-effects, longitudinal time-series research design (from 1995 to 2005) to evaluate the impact of a Medicaid expansion aimed at covering treatment for program clients, enacted via the Breast and Cervical Cancer Prevention and Treatment Act of 2000. In summary, the Treatment Act of 2000 had some positive impacts, including a 12.8% decrease in the average number of days to definitive cervical diagnosis for White women. Nonetheless, the Treatment Act also had some negative impacts on the timing of diagnosis and treatment services, including a significant increase in the average time between a diagnosis of cervical dysplasia or cancer and the initiation of treatment for Black and Hispanic women (7-15 days across age groups). The Treatment Act was also associated with a 9% decrease in the probability that Black women would initiate treatment within 60 days of a cervical diagnosis (-.094; 95% confidence interval [CI] -.178 to -.01). As such, although the Treatment Act had no impact on the proportion of clients who initiated breast cancer treatment within 60 days, it reduced the probability that Black women initiated cervical treatment within an accepted benchmark for timely care.

Access of Black, Hispanic, and nonprivately insured women to liquid-based cytology, human papillomavirus DNA testing, and on-site colposcopy in the United States

OBJECTIVE

To determine whether patient race, ethnicity, or insurance status was associated with access to cervical cancer screening with liquid-based cytology (LBC) and with human papillomavirus (HPV) DNA testing and with access to on-site colposcopy at the provider's principal practice site.

MATERIALS AND METHODS

We conducted a nationally representative survey of clinicians in specialties that provide cervical cancer screening. Adjusted odds ratios (OR) were estimated for the associations between race, ethnicity, and insurance status of patients and provider use of LBC, HPV DNA testing, and on-site colposcopy.

RESULTS

Providers who cared for >or=20% Hispanic patients were less likely to use LBC (OR 0.60, 95% CI=0.42-0.84). Providers who cared for >or=25% black women (OR 0.71, 95% CI=0.51-0.98) and providers who cared for <75% privately insured patients (OR 0.66, 95% CI=0.46-0.95) were less likely to use HPV DNA testing. Providers who cared for <75% privately insured patients were less likely to have on-site colposcopy (OR 0.57, 95% CI=0.37-0.89), but those who cared for >or=20% Medicaid patients were more likely to have on-site colposcopy (OR 1.86, 95% CI=1.26-2.73).

CONCLUSIONS

Given the high rates of cervical cancer in minority women, access to cervical cancer screening and diagnostic follow-up must be ensured. It may also be beneficial to ensure affordable access to technologies such HPV DNA testing that increases the sensitivity of disease detection and to on-site colposcopy that facilitates follow-up of abnormal cytology.

Assessment of follow-up for low-grade cytological abnormalities in the National Breast and Cervical Cancer Early Detection Program, 2000-2005

OBJECTIVE

To assess the management of women in the National Breast and Cervical Cancer Early Detection Program with low-grade squamous intraepithelial lesions (LSIL) before and after the American Society for Colposcopy and Cervical Pathology (ASCCP) guidelines for management of abnormal cytology were published in 2002.

MATERIALS AND METHODS

We examined the follow-up for 22,342 women with LSIL during 2 periods: 2000-2002 and 2003-2005.

RESULTS

The percentage of providers who followed the recommended guidelines with colposcopy for an LSIL Pap test result increased by 9% from the pre-ASCCP to the post-ASCCP period. An increase was seen in every age and racial/ethnic group. Younger women (<30 years) and white women were more likely than comparison groups to be followed by colposcopy rather than a repeat Pap test.

CONCLUSIONS

The increase in percentage of women having colposcopy in 2003, 1 year after the new guidelines were published, suggests a change in provider practices consistent with those guidelines.

Cancer screenings, diagnostic technology evolution, and cancer control

Screening should allow for the anticipation of cancer diagnosis at an earlier stage, when curative treatment is possible. Screening for cervical, large bowel, and breast cancer were shown to be effective in reducing mortality. The wide acceptance of the screening concept led to the wide diffusion also of screening of uncertain benefit against prostate cancer and skin melanoma. Diagnostic technologies are continuously evolving, and new tests are proposed to improve existing screenings or as screening tests for additional cancer sites (e.g., lung cancer). Cancer screening, however, is a complex and costly intervention that does not result only in benefits but also may cause harm. A major emerging problem of screening is overdiagnosis, or the detection of cases that would have not progressed to the symptomatic phase in the absence of screening. Thus, both experimental and observational evaluation studies are needed to reduce harm caused by screenings and to select effective interventions among many proposed innovations. Finally, the research of markers to assess the aggressive nature of screen-detected lesions is of great importance to improve screenings ' harm/benefit ratio.

Human papillomavirus and cervical cancer behavioral surveillance in the US

In the US, federal and state behavioral surveillance systems routinely monitor self-reported sexual behavior and Papanicolaou (Pap) test use to identify high-risk populations, trends, and disparities and to guide and evaluate interventions for cervical cancer prevention and control. Clinical uptake of human papillomavirus (HPV) vaccination and testing necessitates the expansion of behavioral surveillance systems. Cervical disease is the main focus of HPV-related behavioral surveillance because of greater cancer incidence and mortality relative to other susceptible organs, and the availability of effective technologies for prevention and control. In the current study, a framework is presented for the types of behaviors to monitor, their conceptual and operational definitions, target populations, and evidence supporting the reliability and validity of self-report measures. An overview is also provided of 8 population-based and 2 provider-based data systems that are nationally representative and accessible for behavioral surveillance research. Ongoing surveillance at the national, state, and local level is critical for monitoring the dissemination of HPV technologies and their impact on reducing disparities in the detection of precursor lesions, incidence of invasive cancer, and mortality.

Preventing cervical cancer : overviews of the National Breast and Cervical Cancer Early Detection Program and 2 US immunization programs

Three federal programs with the potential to reduce cervical cancer incidence, morbidity, and mortality, especially among underserved populations, are administered by the Centers for Disease Control and Prevention (CDC): the National Breast and Cervical Cancer Early Detection Program (NBCCEDP), the Vaccines for Children (VFC) Program, and the Section 317 immunization grant program. The NBCCEDP provides breast and cervical cancer screening and diagnostic services to uninsured and underinsured women. The VFC program and the Section 317 immunization grant program provide vaccines, including human papillomavirus (HPV) vaccine, to targeted populations at no cost for these vaccines. This article describes the programs, their histories, populations served, services offered, and roles in preventing cervical cancer through HPV vaccination and cervical cancer screening. Potential long-term reduction in healthcare costs resulting from HPV vaccination is also discussed. As an example of an initiative to vaccinate uninsured women aged 19-26 years through a cancer services program, a state-based effort that was recently launched in New York, is highlighted.
