ABSTRACT
Importance: To inform the design and implementation of targeted interventions to reduce the future burden of human papillomavirus (HPV)-related cancers in Texas, it is necessary to examine the county and health service region (HSR) levels of (1) the proportion of children and teenagers aged 9 to 17 years who initiated and were up to date for HPV vaccination series and (2) HPV-related cancer incidence rates (IRs). Objective: To evaluate temporal trends and geospatial patterns of HPV vaccination initiation and up-to-date status as well as HPV-related cancer rates at county and HSR levels in Texas. Design, Setting, and Participants: This population-based cross-sectional study used data from the Texas Immunization Registry, the National Cancer Institute's Surveillance, Epidemiology, and End Results Program database, and Texas Department of State Health Services annual population counts from 2006 to 2022. The analysis of HPV vaccination rates was conducted among children and teenagers aged 9 to 17 years; the analysis of HPV-related cancer rates was conducted among adults aged 20 years and older. Data were extracted between June and July 2023 and statistical analysis was performed from February to April 2024. Main Outcomes and Measures: HPV vaccination initiation and up-to-date status rates and HPV-related cancer IR at county and HSR levels. Results: A total of 32â¯270â¯243 children and teenagers (65.8% female individuals and 34.2% male individuals) and 22â¯490â¯105 individuals aged 20 years and older (50.7% female individuals and 49.3% male individuals) were included. The mean 2021 to 2022 county-level HPV vaccination series initiation estimates ranged from 6.3% to 69.1% for female and from 7.0% to 77.6% for male children and teenagers aged 9 to 17 years. County-level vaccination up-to-date estimates were generally lower compared with those of initiation estimates and ranged from 1.6% to 30.4% for female and from 2.1% to 34.8% for male children and teenagers. The pattern of HPV vaccination rates stratified by sex were similar across counties and HSRs. The age-adjusted annual HPV-related cancer IR by county for years 2016 to 2020 ranged from 0 to 154.2 per 100â¯000 for female individuals and from 0 to 60.1 per 100â¯000 for male individuals. The counties located in North Texas, HSRs 2/3 and 4/5N, had lower HPV vaccination rates and higher IRs of HPV-related cancers for both female and male individuals compared with other regions. Conclusions and Relevance: In this study, the incidence of HPV-related cancers varied widely across the counties and HSRs of Texas. More counties in North Texas, HSRs 2/3 and 4/5N, had higher IRs of HPV-related cancers and a lower proportion of HPV vaccination rates than counties in other regions. Designing and implementing targeted interventions to increase uptake and completion of HPV vaccination series across counties with low HPV vaccination rates may help to reduce future the burden of HPV-related cancers.

BACKGROUND: While cervical cancer incidence rates (IR) in the United States have dropped in the last 20 years, non-cervical human papillomavirus (HPV) associated cancers increased. Many people in Texas (TX) live in medically underserved areas and have higher risk of developing HPV-associated cancers. Since previous studies of these regions focused on cervical cancer, we included other HPV-associated cancers in our analysis of IR in East TX and the TX-Mexico Border compared to other TX regions. METHODS: Cancer data from 2006 to 2019 were obtained from the TX Cancer Registry. Cases of HPV-associated cervical, vaginal, vulvar, penile, anal, and oropharyngeal cancers and corresponding patient-level demographic data were included. We calculated IR per 100,000 and drew heat maps to visualize cancer IR by county. To control potential confounders, we added county-level risk factors: rates for smoking, excessive drinking, obesity, STIs, primary care provider availability and dentist availability, from the County Health Rankings and Roadmaps program. We reported IRs by region and time and estimated unadjusted and adjusted risk ratio (RR) for association of each type of cancer and region. Lastly, we created adjusted models for each cancer by period to see time trends of regional differences. RESULTS: Risk of anal, cervical, and oropharyngeal cancer was lower at parts of the Border than in the rest of TX in the adjusted model. We also observed increasing anal and oropharyngeal cancer risk and decreasing cervical and vaginal cancer risk over time. CONCLUSION: Patient sociodemographics, behavioral risk factors, and access to care may contribute to some observed differences in cancer IR across regions. This indicates that targeted prevention efforts towards these regions, especially in low socioeconomic status communities, may benefit future generations.

BACKGROUND: Kidney transplant recipients (KTRs) have elevated risks of cervical pre-cancers and cancers, and guidelines recommend more frequent cervical cancer screening exams. However, little is known about current trends in cervical cancer screening in this unique population. We described patterns in the uptake of cervical cancer screening exams among female KTRs and identified factors associated with screening utilization. METHODS: This retrospective cohort study included female KTRs between 20-65 years old, with Texas Medicare fee-for-service coverage, who received a transplant between January 1, 2001, and December 31, 2017. We determined the cumulative incidence of receiving cervical cancer screening post-transplant using ICD-9, ICD-10, and CPT codes and assessed factors associated with screening utilization, using the Fine and Gray model to account for competing events. Subdistribution hazards models were used to assess factors associated with screening uptake. RESULTS: Among 2,653 KTRs meeting the inclusion and exclusion criteria, the 1-, 2-, and 3-year cumulative incidences of initiating a cervical cancer screening exam post-transplant were 31.7% (95% confidence interval (CI), 30.0-33.6%), 48.0% (95% CI, 46.2-49.9%), and 58.5% (95% CI, 56.7-60.3%), respectively. KTRs who were 55-64 years old (vs. <45 years old) and those with a higher Charlson Comorbidity Score post-transplant were less likely to receive cervical cancer screening post-transplant. CONCLUSIONS: Cervical cancer screening uptake is low in the years immediately following a kidney transplant. IMPACT: Our findings highlight a need for interventions to improve cervical cancer screening utilization among KTRs.
ABSTRACT
Endometrial cancer has continued to see a rising incidence in the US over the years. The main aim of this study was to assess current trends in patients' characteristics and outcomes of treatment for endometrial carcinoma over 16 years. A dataset from the National Cancer Database (NCDB) for patients diagnosed with endometrial carcinoma from 2005 to 2020 was used in this retrospective, case series study. The main outcomes and measures of interest included tumor characteristics, hospitalization, treatments, mortality, and overall survival. Then, 569,817 patients who were diagnosed with endometrial carcinoma were included in this study. The mean (SD) age at diagnosis was 62.7 (11.6) years, but 66,184 patients (11.6%) were younger than 50 years, indicating that more patients are getting diagnosed at younger ages. Of the patients studied, 37,079 (6.3%) were Hispanic, 52,801 (9.3%) were non-Hispanic Black, 432,058 (75.8%) were non-Hispanic White, and 48,879 (8.6%) were other non-Hispanic. Patients in the 4th period from 2017 to 2020 were diagnosed more with stage IV (7.1% vs. 5.2% vs. 5.4% vs. 5.9%; p < 0.001) disease compared with those in the other three periods. More patients with severe comorbidities (Charlson Comorbidity Index score of three) were seen in period 4 compared to the first three periods (3.9% vs. ≤1.9%). Systemic chemotherapy use (14.1% vs. 17.7% vs. 20.4% vs. 21.1%; p < 0.001) and immunotherapy (0.01% vs. 0.01% vs. 0.2% vs. 1.1%; p < 0.001) significantly increased from period 1 to 4. The use of laparotomy decreased significantly from 42.1% in period 2 to 16.7% in period 4, while robotic surgery usage significantly increased from 41.5% in period 2 to 64.3% in period 4. The 30-day and 90-day mortality decreased from 0.6% in period 1 to 0.2% in period 4 and 1.4% in period 1 to 0.6% in period 4, respectively. Over the period studied, we found increased use of immunotherapy, chemotherapy, and minimally invasive surgery for the management of endometrial cancer. Overall, the time interval from cancer diagnosis to final surgery increased by about 6 days. The improvements observed in the outcomes examined can probably be associated with the treatment trends observed.
ABSTRACT
Importance: The current method of BRCA testing for breast and ovarian cancer prevention, which is based on family history, often fails to identify many carriers of pathogenic variants. Population-based genetic testing offers a transformative approach in cancer prevention by allowing for proactive identification of any high-risk individuals and enabling early interventions. Objective: To assess the lifetime incremental effectiveness, costs, and cost-effectiveness of population-based multigene testing vs family history-based testing. Design, Setting, and Participants: This economic evaluation used a microsimulation model to assess the cost-effectiveness of multigene testing (BRCA1, BRCA2, and PALB2) for all women aged 30 to 35 years compared with the current standard of care that is family history based. Carriers of pathogenic variants were offered interventions, such as magnetic resonance imaging with or without mammography, chemoprevention, or risk-reducing mastectomy and salpingo-oophorectomy, to reduce cancer risk. A total of 2000 simulations were run on 1â¯000â¯000 women, using a lifetime time horizon and payer perspective, and costs were adjusted to 2022 US dollars. This study was conducted from September 1, 2020, to December 15, 2023. Main Outcomes and Measures: The main outcome measure was the incremental cost-effectiveness ratio (ICER), quantified as cost per quality-adjusted life-year (QALY) gained. Secondary outcomes included incremental cost, additional breast and ovarian cancer cases prevented, and excess deaths due to coronary heart disease (CHD). Results: The study assessed 1â¯000â¯000 simulated women aged 30 to 35 years in the US. In the base case, population-based multigene testing was more cost-effective compared with family history-based testing, with an ICER of $55â¯548 per QALY (95% CI, $47â¯288-$65â¯850 per QALY). Population-based multigene testing would be able to prevent an additional 1338 cases of breast cancer and 663 cases of ovarian cancer, but it would also result in 69 cases of excess CHD and 10 excess CHD deaths per million women. The probabilistic sensitivity analyses show that the probability that population-based multigene testing is cost-effective was 100%. When the cost of the multigene test exceeded $825, population-based testing was no longer cost-effective (ICER, $100â¯005 per QALY; 95% CI, $87â¯601-$11â¯6323). Conclusions and Relevance: In this economic analysis of population-based multigene testing, population-based testing was a more cost-effective strategy for the prevention of breast cancer and ovarian cancer when compared with the current family history-based testing strategy at the $100â¯000 per QALY willingness-to-pay threshold. These findings support the need for more comprehensive genetic testing strategies to identify pathogenic variant carriers and enable informed decision-making for personalized risk management.

Studies have suggested the effectiveness of COVID-19 vaccines in preventing SARS-CoV-2 reinfection among those previously infected. However, it is not yet clear if one dose of the vaccine is enough to prevent breakthrough infections compared to two doses. Using data from Optum deidentified COVID-19 Electronic Health Record (EHR) data set, we assessed breakthrough infection risks in individuals previously infected, comparing those with one vaccine dose to those with two doses. Propensity scores were applied to mitigate confounding factors. Follow-up spanned 6 months, beginning 2 weeks postvaccination. Among 213 845 individuals, those receiving one vaccine dose had a significantly higher breakthrough infection risk than the two-dose group (HR 1.69, 95% CI 1.54-1.85). This pattern was observed across genders, racial/ethnic groups, age categories, and vaccine types. This study reveals a substantial disparity in the risk of breakthrough infections between individuals receiving one versus two doses of the COVID-19 vaccine, suggesting that a single dose may not provide adequate protection against reinfection.

INTRODUCTION AND HYPOTHESIS: There is a need for cost effective interventions that increase surgical preparedness in urogynecology. METHODS: We performed an ancillary prospective economic evaluation of the Telehealth Intervention to Increase Patient Preparedness for Surgery (TIPPS) Trial, a randomized multicenter trial that evaluated the impact of a preoperative telehealth call on surgical preparedness in women undergoing urogynecologic surgery. A within-trial analysis from the health care sector and societal perspective was performed. Cost-effectiveness was computed from health care sector and societal perspectives, with an 8-week time horizon. RESULTS: A total of 126 women were included in our analysis. QALYs gained were similar between groups (telehealth 0.1414 + 0.0249; usual care 0.1409 + 0.0179). The cumulative mean per-person costs at 8 weeks from the healthcare sector perspective were telehealth call: $8696 +/- 3341; usual care: $8473 +/- 3118 (p = 0.693) and from the societal perspective were telehealth call: $11,195 + 5191; usual care: $11,213 +/- 4869 (p = 0.944). The preoperative telehealth call intervention was not cost effective from the health care sector perspective with an ICER of $460,091/QALY (95%CI -$7,382,608/QALY, $7,673,961) using the generally accepted maximum willingness to pay threshold of $150,000/QALY (Neumann et al. N Engl J Med. 371(9):796-7, 2014). From the societal perspective, because incremental costs per QALY gained were negative $-35,925/QALY (95%CI, -$382,978/QALY, $317,226), results suggest that preoperative telehealth call dominated usual care. CONCLUSIONS: A preoperative telehealth call is cost effective from the society perspective. CLINICAL TRIAL REGISTRATION: Registered with http://ClinicalTrials.gov .

Background: In the United States, the human papillomavirus (HPV) vaccine is approved for use in individuals up to age 45. Individuals 15 years and older require three doses of the vaccine to complete the recommended dosing series. Incomplete HPV vaccination rates (i.e., one or two doses) among those over age 26, however, remain high. This study examined the independent effects of individual- and neighborhood-level factors on incomplete HPV vaccination rates in the United States (U.S.) among those aged 27-45 years. Methods: This retrospective cohort study used administrative data from Optum's de-identified Clinformatics® Data Mart Database to identify individuals aged 27-45 years who received one or more doses of HPV vaccine between July 2019 and June 2022. Multilevel multivariable logistic regression models were applied to the data on 7662 individuals identified as being fully or partially vaccinated against HPV, nested within 3839 neighborhoods across the U.S. Results: Approximately half of the patients in this study (52.93%) were not completely vaccinated against HPV. After adjusting for all other covariates in the final model, being older than 30 years old decreased the odds of not completing the HPV vaccine series. Participants living in South-region neighborhoods of the U.S. had enhanced odds of not completing the vaccine series compared with those residing in Northeast-region neighborhoods (aOR 1.21; 95% CrI 1.03-1.42). There was significant clustering of incomplete HPV vaccination rates at the neighborhood level. Conclusions: This study revealed that individual- and neighborhood-level factors were associated with the risk of not completing the HPV vaccine series among individuals aged 27-45 years in the U.S. Interventions to improve HPV vaccination series completion rates for this age group should take into consideration both individual and contextual factors.
ABSTRACT
Postmarket surveillance of the incidence of human papillomavirus (HPV)-related cancers is essential to monitor the effectiveness of HPV vaccines. We directly compared HPV-related cancer incidences during the pre- and postvaccine era to assess the effects of HPV vaccination among vaccine-eligible age groups in the United States using data from the US Cancer Statistics database. The 5-year average annual incidence rates for HPV-related cancers decreased in 2015-2019 compared with 2002-2006 among females aged 15-24 years and 25-34 years. Overall, a decrease in young males was not observed, whereas males aged 25-34 years experienced a slight decline in oropharyngeal squamous cell carcinoma between 2005-2009 and 2015-2019. Incidence rates for HPV-related cancers statistically significantly decreased in the vaccine era compared with the prevaccine era among females aged 15-34 years, suggesting the potential early effects of the introduction of HPV vaccination in the United States.

Background: The human papillomavirus (HPV) vaccine was approved in 2006 and has been shown to decrease vaccine-related HPV types in the oropharynx. Its impact on the incidence of HPV-related oropharyngeal squamous cell carcinoma (OPSCC) has not been examined. We investigated the impact of HPV vaccination on the incidence of HPV-related OPSCC in the US among male and female adults from different age groups. Methods: The US Cancer Statistics 2001-2018 database and the National Cancer Institute (NCI)'s Surveillance Epidemiology and End Results (SEER) program were used in this study. OPSCC incidence was age-adjusted to the US standard population in 2000. Cause-specific 5-year survival probability was calculated using 60 monthly intervals in SEER*Stat software. Results: Incidence of HPV-related OPSCC was much higher in males than in females. Age-adjusted annual incidence of OPSCC was significantly lower in 2014-2018 than in 2002-2006 among males 20-44 years old (11.4 vs 12.8 per 1,000,000, rate ratio 0.89, 95% confidence interval 0.84-0.93) and among females 20-44 years old (3.0 vs 3.6 per 1,000,000, rate ratio 0.86, 95% confidence interval 0.78-0.95), but increased in both 45-64 year old and 65+ year old males and females. Joinpoint regression revealed a significant joint in the HPV-OPSCC incidence trend for 20-44-year-old males in 2008 at which time the incidence began to decrease. Except for 20-44 year old females (74.8% in 2002-2006 vs. 75.7% in 2009-2013, p=0.84), cancer-specific 5-year survivals significantly improved for males and females of all age groups. Conclusions: HPV-related OPSCC was much more common in males. Incidence of HPV-related OPSCC declined among young adults during the vaccination era compared with pre-vaccination era. Cancer-specific 5-year survival was significantly improved in young males but not in young females.
ABSTRACT
Since the 1990 s discovery of BRCA1 and BRCA2 pathogenic variants in breast or ovarian cancer patients, genetic testing has been recommended as part of a targeted, individualized approach for cancer prevention and treatment in eligible individuals. The aim of this study was to assess trends in BRCA test rates and results among adult women aged 18 to 65 in the US between 2007 and 2017. Using Clinformatics© Data Mart (CDM) Electronic Health Records, we included 223,211 women 18-65 years old with documented BRCA testing results from 1/1/2007-9/30/2017. Positive results indicated the presence of pathogenic variantss. BRCA test rates increased significantly from 34 per 100,000 women in 2007 to 488 per 100,000 women in 2016 (APC 30.8, 95% confidence interval 26.6-35.1). Documented positive results decreased from 86.1% in 2007 to 78.0% in 2017(APC -0.6, 95% confidence interval -1.4-0.2). From 2007 to 2017, decreasing trends in the rates of documented positive results were observed among all three age groups (18-39, 40-54, and 55-65 years; largest in 40-54 group). In 2015-2017, women with positive test results were less likely to be non-Hispanic Whites, cancer patients, or living in the Northeast or an area with average household income ≥$50,000. Between 2007 and 2017, increasing use of BRCA testing for cancer prevention and treatment occurred, correlating to the observed decreasing documented positive test rate. The utilization of testing and corresponding test results differed significantly across races/ethnicities, suggestive of a divergent application of the same testing criteria.

Knowledge, attitudes, and patient preferences about genetic testing and subsequent risk management for cancer prevention among average risk populations are understudied, especially among Hispanics. This study was to assess these items by conducting an in-person survey in this understudied population. We conducted in-person surveys using a self-administered, structured questionnaire among young women in 2017. Survey questions were adapted from other validated surveys. This study had 677 participants in the final analyses. Data were collected in 2017 and analyzed in 2018 and 2019. Participants had little knowledge about genes or breast cancer risk, but most felt that genetic testing for cancer prevention is "a good idea" (87.0%), "a reassuring idea" (84.0%), and that "everyone should get the test" (87.7%). Most (64.0%) of these women would pay up to $25 for the test, 29.3% would pay $25-$500, and < 10% would pay more than $500 for the test. When asked about a hypothetical scenario of high breast cancer risk, 34.2% Hispanics and 24.5% non-Hispanics would choose chemoprevention. Women would be less likely to choose risk reduction procedures, such as mastectomy (19.6% among Hispanics and 15.1% among non-Hispanics) and salpingo-oophorectomy (11.8% among Hispanics and 10.7% among non-Hispanics). In this low-income, mostly Hispanic population, knowledge about genetic testing and cancer risk is poor, but most have positive opinions about genetic testing for cancer prevention. However, their strong preference for chemoprevention and lesser preference for prophylactic surgeries in a hypothetical scenario underscore the importance of genetic counseling and education.

Childhood vaccination is an important public health intervention, yet many children remain under-vaccinated. The objective of this study was to examine infant vaccination education preferences in a population of low-income pregnant women by ethnicity, nativity, and language. Pregnant women 14-44 y old (n = 335) attending a participating low-income reproductive health clinic in southeast Texas from May 26-July 21, 2017, and who completed a paper survey offered in English and Spanish were included. Participants were asked to complete questions about their demographic characteristics and preferences about infant vaccination education. To examine differences in vaccine education preferences by participant demographic characteristics, chi-squared tests, or Fisher's exact tests and one-way analysis of variance (ANOVA) were conducted using Stata SE Version 15.1 with α = 0.05. Nearly half (47.5%) of participants considered pregnancy the best time to get information about infant vaccination and were most likely (40.6%) to indicate the nurse who gives vaccines during pregnancy as the health-care worker with whom they would like to discuss infant vaccination. There were no demographic differences in preferred timing of vaccine education delivery or provider who delivers vaccine education. Prenatal, nurse-delivered vaccine educational programs would be well accepted in this low-income population.

Importance: Genetic testing for BRCA1/2 pathogenic variants has been used for targeted, individualized cancer prevention and treatment. A positive BRCA test result indicates a higher risk for developing BRCA-related cancers. During the past decade, testing criteria have loosened. The impact of these loosened criteria on BRCA testing in older women has not previously been studied. Objective: To assess whether the rate of positive BRCA test results changed between 2008 and 2018 among older women in the United States. Design, Setting, and Participants: This cross-sectional study used a 10% random sample of women 65 years of age or older from Optum's deidentified Integrated Claims-Clinical data set (2008-2018), a large national electronic health record data set. A total of 5533 women with BRCA test results from January 1, 2008, to March 31, 2018, were evaluated. Main Outcomes and Measures: Annual percentage change in positive BRCA test results was evaluated. Multivariable logistic regression models were used to assess the association between positive test results and race/ethnicity, region of residence, income, educational level, and personal history of breast or ovarian cancer. Results: Of 5533 women 65 years of age or older (mean age, 68.1 years [95% CI, 67.9-68.4 years]) who underwent BRCA testing from 2008 to 2018, most (4679 [84.6%]) were non-Hispanic White women, and 1915 (34.6%) resided in the Midwest. Positive BRCA test results decreased from 85.7% (36 of 42) in 2008 to 55.6% (140 of 252) in 2018 (annual percentage change, -2.55; 95% CI, -3.45 to -1.64). Among patients with breast or ovarian cancer, positive test results decreased from 83.3% (20 of 24) in 2008 to 61.6% (61 of 99) in 2018, while among women without breast or ovarian cancer, positive test results decreased from 87.5% (21 of 24) in 2008 to 48.4% (74 of 153) in 2018 (annual percentage change, -3.17 vs -2.49; P = .29). Women with positive test results were more likely to be non-Hispanic Black women, to live in the West or South, to live in areas with a low percentage of college graduates, or to not have a personal history of breast or ovarian cancer. Conclusions and Relevance: This study suggests that there was a significantly decreasing rate of positive BRCA test results among women 65 years of age or older. Socioeconomic and regional disparities in testing use remain an issue.

BACKGROUND: Team care improves processes and outcomes of care, especially for patients with complex medical conditions that require coordination of care. This study aimed to compare the processes and outcomes of care provided to older patients with diabetes by primary care teams comprised of only primary care physicians (PCPs) versus team care that included nurse practitioners (NPs) or physician assistants (PAs). METHODS: We studied 3,524 primary care practices identified via social network analysis and 306,741 patients ≥66 years old diagnosed with diabetes in or before 2015 in Medicare data. Guideline-recommended diabetes care included eye examination, hemoglobin A1c test, and nephropathy monitoring. High-risk medications were based on recommendations from the American Geriatrics Society Beers Criteria for Potentially Inappropriate Medication Use in Older Adults. Preventable hospitalizations were defined as hospitalizations for a potentially preventable condition. RESULTS: Compared with patients in the PCP only teams, patients in the team care practices with NPs or PAs received more guideline-recommended diabetes care (annual eye exam: adjusted odds ratio (aOR): 1.04 (95% CI: 1.00-1.08), 1.08 (95% CI: 1.03-1.13), and 1.10 (95% CI: 1.05-1.15), and HbA1C test: aOR: 1.11 (95% CI: 1.04-1.18), 1.11 (95% CI: 1.02-1.20), and 1.15 (95% CI: 1.06-1.25) for PCP/NP, PCP/NP/PA, and PCP/PA teams). Patients in the PCP/NP and the PCP/PA teams had a slightly higher likelihood of being prescribed high-risk medications (aOR: 1.03 (95% CI: 1.00-1.07), and 1.06 (95% CI: 1.02-1.11), respectively). The likelihood of preventable hospitalizations was similar among patients cared for by various types of practices. CONCLUSION: The team care practices with NPs or PAs were associated with better adherence to clinical practice guideline recommendations for diabetes compared to PCP only practices. Both practices had similar outcomes. Further efforts are needed to explore new and cost-effective team-based care delivery models that improve process, outcomes, and continuity of care, as well as patient care experiences.

BACKGROUND: The discovery of the BRCA gene in the 1990s created an opportunity for individualized cancer prevention. BRCA testing in young women before cancer onset enables early detection of those with an increased cancer risk and creates an opportunity to offer lifesaving prophylactic procedures and medications. This study assessed trends in BRCA testing in women younger than 40 years without diagnosed breast or ovarian cancer (unaffected young women [UYW]) for cancer prevention between 2006 and 2017 in the United States. METHODS: This study included 93,278 adult women 18 to 65 years old with insurance claims for BRCA testing between 2006 and 2017 from the de-identified Optum Clinformatics Data Mart database. The data contained medical claims and administrative information from privately insured individuals in the United States. The proportion of BRCA testing in UYW younger than 40 years among adult women aged 18 to 65 years who received BRCA testing was assessed. RESULTS: In 2006, only 10.5% of the tests were performed in UYW. The proportion of BRCA tests performed in UYW increased significantly to 25.5% in 2017 (annual percentage change for the 2006-2017 period, 6.9; 95% confidence interval, 6.4-7.3; P < .001). The increased trend in the proportion of BRCA tests in UYW significantly differed by region of residence and family history of breast or ovarian cancer. CONCLUSIONS: Over the past decade, there was increased use of BRCA testing for cancer prevention. Additional efforts are needed to maximize the early detection of women with BRCA pathogenic variants so that these cancers may be prevented.

INTRODUCTION: The U.S. Preventive Services Task Force changed breast cancer screening guidelines in November 2009 for mammograms in women aged 40-49 and 50-74 years. The aim of this study was to assess the impact of the 2009 guideline changes on breast cancer incidence by stage among women aged 40-49 and 50-74 years in the U.S. METHODS: This was a cross-sectional trend analysis of the impact of 2009 guideline change on breast cancer incidence by stage, using data from the National Program for Cancer Registries and Surveillance, Epidemiology, and End Results Incidence-U.S. Cancer Statistics 2001-2014 database among women aged 40-74 years. Incidence was age adjusted to the U.S. standard population. Data were collected in 2001-2014, released in 2017, and analyzed in 2018. RESULTS: Among women aged 40-49 years, the 4-year average annual incidence of breast cancer increased slightly in 2011-2014 for in situ, localized, and distant cancer, but decreased for regional cancer compared with the incidence in 2006-2009. Among women aged 50-74 years, the 4-year average annual incidence of breast cancer increased in 2011-2014 for localized and distant cancer, but decreased for in situ and regional cancer. Joinpoint analyses revealed that annual percentage changes decreased after 2009 for distant cancer among both women aged 40-49 and 50-74 years. The composition of breast cancer by stage was similar between 2006-2009 and 2011-2014 among both women aged 40-49 and 50-74 years. CONCLUSIONS: Changes in breast cancer screening by the 2009 U.S. Preventive Services Task Force guidelines had little immediate adverse effects on the stage distribution of breast cancer diagnoses in the U.S. Monitoring the incidence by cancer stages over time is needed.
