Costs and Projected Effect of a Federally Qualified Health Center-Based Mailed Colorectal Cancer Screening Program in Texas.

Introduction: Mailed stool testing for colorectal cancer (CRC) may improve screening uptake and reduce the incidence and mortality of CRC, especially among patients at federally qualified health centers (FQHCs). To expand screening programs it is important to identify cost-effective approaches. Methods: We developed a decision-analytic model to estimate the cost, effects on screening and patient outcomes (CRCs detected, CRCs prevented, CRC deaths prevented), and cost-effectiveness of implementing a state-wide mailed stool testing program over 5 years among unscreened, age-eligible (aged 50-75 y) patients at FQHCs in Texas. We compared various outreach strategies and organizational structures (centralized, regional, or a hybrid). We used data from our existing regional mailed stool testing program and recent systematic reviews to set parameters for the model. Costs included start-up and ongoing activities and were estimated in 2022 US dollars from the perspective of a hypothetical third-party payer. Cost-effectiveness was assessed by using both incremental and average cost-effectiveness ratios. Results: Using either a statewide centralized or hybrid organizational configuration to mail stool tests to newly eligible FQHC patients and patients who have responded at least once since program inception is likely to result in the best use of resources over 5 years, enabling more than 110,000 additional screens, detecting an incremental 181 to 194 CRCs, preventing 91 to 98 CRCs, and averting 46 to 50 CRC deaths, at a cost of $10 million to $11 million compared with no program. Conclusions: A statewide mailed stool testing program for FQHC patients can be implemented at reasonable cost with considerable effects on CRC screening outcomes, especially when its structure maximizes program efficiency while maintaining effectiveness.

Barriers to Cervical Cancer Screening by Sexual Orientation Among Low-Income Women in North Carolina.

We sought to examine cervical cancer screening barriers by sexual orientation among low-income women in North Carolina. The MyBodyMyTest-3 Trial recruited low-income women (< 250% of federal poverty level) aged 25-64 years who were 1+ year overdue for cervical cancer screening. We compared perceptions of cervical cancer screening among those who self-identified as lesbian, gay, bisexual, or queer (LGBQ; n = 70) to straight/heterosexual women (n = 683). For both LGBQ and straight respondents, the greatest barriers to screening were lack of health insurance (63% and 66%) and cost (49% and 50%). LGBQ respondents were more likely than straight respondents to report forgetting to screen (16% vs. 8%, p = .05), transportation barriers (10% vs. 2%, p = .001), and competing mental or physical health problems (39% vs. 27%, p = .10). Addressing access remains important for improving cervical cancer screening among those under-screened. For LGBQ women, additional attention may be needed for reminders, co-occurring health needs, and transportation barriers.

Inclusion of marginalized populations in HPV vaccine modeling: A systematic review.

OBJECTIVE: Models simulating the potential impacts of Human Papillomavirus (HPV) vaccine have been used globally to guide vaccination policies and programs. We sought to understand how and why marginalized populations have been incorporated into HPV vaccine simulation models. METHODS: We conducted a systematic search of PubMed, CINAHL, Scopus, and Embase to identify studies using simulation models of HPV vaccination incorporating one or more marginalized population through stratification or subgroup analysis. We extracted data on study characteristics and described these overall and by included marginalized groups. RESULTS: We identified 36 studies that met inclusion criteria, which modeled vaccination in 21 countries. Models included men who have sex with men (MSM; k = 16), stratification by HIV status (k = 9), race/ethnicity (k = 6), poverty (k = 5), rurality (k = 4), and female sex workers (k = 1). When evaluating for a marginalized group (k = 10), HPV vaccination was generally found to be cost-effective, including for MSM, individuals living with HIV, and rural populations. In studies evaluating equity in cancer prevention (k = 9), HPV vaccination generally advanced equity, but this was sensitive to differences in HPV vaccine uptake and use of absolute or relative measures of inequities. Only one study assessed the impact of an intervention promoting HPV vaccine uptake. DISCUSSION: Incorporating marginalized populations into decision models can provide valuable insights to guide decision making and improve equity in cancer prevention. More research is needed to understand the equity impact of HPV vaccination on cancer outcomes among marginalized groups. Research should emphasize implementation - including identifying and evaluating specific interventions to increase HPV vaccine uptake.

Financial burden among metastatic breast cancer patients: a qualitative inquiry of costs, financial assistance, health insurance, and financial coping behaviors.

PURPOSE: Metastatic breast cancer (MBC) patients often face substantial financial burden due to prolonged and expensive therapy. However, in-depth experiences of financial burden among MBC patients are not well understood. METHODS: Qualitative interviews were conducted to describe the experiences of financial burden for MBC patients, focusing on the drivers of financial burden, their experience using their health insurance, accessing financial assistance, and any resulting cost-coping behaviors. Interviews were transcribed and qualitatively analyzed using a descriptive phenomenological approach to thematic analysis. RESULTS: A total of n = 11 MBC patients or caregiver representatives participated in the study. MBC patients were on average 50.2 years of age (range: 28-65) and 72.7% non-Hispanic White. MBC patients were diagnosed as metastatic an average of 3.1 years (range: 1-9) before participating in the study. Qualitative analysis resulted in four themes including (1) causes of financial burden, (2) financial assistance mechanisms, (3) health insurance and financial burden, and (4) cost-coping behaviors. Both medical and non-medical costs drove financial burden among participants. All participants reported challenges navigating their health insurance and applying for financial assistance. Regardless of gaining access to assistance, financial burden persisted for nearly all patients and resulted in cost-coping behaviors. CONCLUSION: Our findings suggest that current systems for health insurance and financial assistance are complex and difficult to meet patient needs. Even when MBC patients accessed assistance, excess financial burden persisted necessitating use of financial coping-behaviors such as altering medication use, maintaining employment, and taking on debt.

Adapting a model of cervical carcinogenesis to self-identified Black women to evaluate racial disparities in the United States.

BACKGROUND: Self-identified Black women in the United States have higher cervical cancer incidence and mortality than the general population, but these differences have not been clearly attributed across described cancer care inequities. METHODS: A previously established microsimulation model of cervical cancer was adapted to reflect demographic, screening, and survival data for Black US women and compared with a model reflecting data for all US women. Each model input with stratified data (all-cause mortality, hysterectomy rates, screening frequency, screening modality, follow-up, and cancer survival) was sequentially replaced with Black-race specific data to arrive at a fully specified model reflecting Black women. At each step, we estimated the relative contribution of inputs to observed disparities. RESULTS: Estimated (hysterectomy-adjusted) cervical cancer incidence was 8.6 per 100 000 in the all-race model vs 10.8 per 100 000 in the Black-race model (relative risk [RR] = 1.24, range = 1.23-1.27). Estimated all-race cervical cancer mortality was 2.9 per 100 000 vs 5.5 per 100 000 in the Black-race model (RR = 1.92, range = 1.85-2.00). We found the largest contributors of incidence disparities were follow-up from positive screening results (47.3% of the total disparity) and screening frequency (32.7%). For mortality disparities, the largest contributor was cancer survival differences (70.1%) followed by screening follow-up (12.7%). CONCLUSION: To reduce disparities in cervical cancer incidence and mortality, it is important to understand and address differences in care access and quality across the continuum of care. Focusing on the practices and policies that drive differences in treatment and follow-up from cervical abnormalities may have the highest impact.

Knowledge, Attitudes, and Resources of Frontline Oncology Support Personnel Regarding Financial Burden in Patients With Cancer.

PURPOSE: Financial navigation services support patients with cancer and address the direct and indirect financial burden of cancer diagnosis and treatment. These services are commonly delivered through a variety of frontline oncology support personnel (FOSP) including navigators, social workers, supportive care providers, and other clinic staff, but the perspective of FOSPs is largely absent from current literature on financial burden in oncology. We surveyed a national sample of FOSPs to understand their perspectives on patient financial burden, resource availability, and barriers and facilitators to assisting patients with cancer-related financial burden. METHODS: We used Qualtrics online survey software and recruited participants using multiple professional society and interest group mailing lists. Categorical responses were described using frequencies, distributions of numeric survey responses were described using the median and IQR, and two open-ended survey questions were categorized thematically using a priori themes, allowing additional emergent themes. RESULTS: Two hundred fourteen FOSPs completed this national survey. Respondents reported a high awareness of patient financial burden and felt comfortable speaking to patients about financial concerns. Patient assistance resources were commonly available, but only 15% described resources as sufficient for the observed needs. A substantial portion of respondents reported moral distress related to this lack of resources. CONCLUSION: FOSPs, who already have requisite knowledge and comfort in discussing patient financial needs, are a critical resource for mitigating cancer-related financial burden. Interventions should leverage this resource but prioritize transparency and efficiency to reduce the administrative and emotional toll on the FOSP workforce and reduce the risk of burnout.

Multidimensional financial hardship among uninsured and insured young adult patients with metastatic breast cancer.

BACKGROUND: Little is known about the heterogeneous nature of financial hardship in younger patients with metastatic disease and the extent to which insurance protects against it. We examine the association between insurance status and multidimensional indicators of financial hardship in a national sample of women with metastatic breast cancer. METHODS: We conducted a national, retrospective online survey in partnership with the Metastatic Breast Cancer Network. Eligible participants were ≥18 years, diagnosed with metastatic breast cancer, and able to respond in English. We estimated multivariate generalized linear models predicting two distinct dimensions of financial hardship-financial insecurity (the ability to afford care and living costs) and financial distress (the extent of emotional/psychological distress experienced due to costs)-as a function of insurance status. RESULTS: Participants responded from 41 states (N = 1054; median age: 44 years). Overall, 30% were uninsured. Financial insecurity was more frequently reported by uninsured respondents. In adjusted analyses, uninsured participants were more likely than insured participants to report contact by debt collectors (adjusted risk ratio [aRR]: 2.38 [2.06, 2.76]) and being unable to meet monthly expenses (aRR: 2.11 [1.68, 2.66]). Financial distress was reported more frequently by insured participants. For example, insured participants were more likely to worry about future financial problems due to cancer and distress about lack of cost transparency. After adjustment, uninsured participants remained about half as likely as insured participants to report financial distress. CONCLUSIONS: Young adult women with metastatic cancer reported a high burden of financial toxicity. Importantly, insurance does not protect against financial distress; however, the uninsured are the most materially vulnerable.

Racial and Ethnic Disparities in Cervical Cancer Screening From Three U.S. Healthcare Settings.

INTRODUCTION: This study sought to characterize racial and ethnic disparities in cervical cancer screening and follow-up of abnormal findings across 3 U.S. healthcare settings. METHODS: Data were from 2016 to 2019 and were analyzed in 2022, reflecting sites within the Multi-level Optimization of the Cervical Cancer Screening Process in Diverse Settings & Populations Research Center, part of the Population-based Research to Optimize the Screening Process consortium, including a safety-net system in the southwestern U.S., a northwestern mixed-model system, and a northeastern integrated healthcare system. Screening uptake was evaluated among average-risk patients (i.e., no previous abnormalities) by race and ethnicity as captured in the electronic health record, using chi-square tests. Among patients with abnormal findings requiring follow-up, the proportion receiving colposcopy or biopsy within 6 months was reported. Multivariable regression was conducted to assess how clinical, socioeconomic, and structural characteristics mediate observed differences. RESULTS: Among 188,415 eligible patients, 62.8% received cervical cancer screening during the 3-year study period. Screening use was lower among non-Hispanic Black patients (53.2%) and higher among Hispanic (65.4%,) and Asian/Pacific Islander (66.5%) than among non-Hispanic White patients (63.5%, all p<0.001). Most differences were explained by the distribution of patients across sites and differences in insurance. Hispanic patients remained more likely to screen after controlling for a variety of clinical and sociodemographic factors (risk ratio=1.14, CI=1.12, 1.16). Among those receiving any screening test, Black and Hispanic patients were more likely to receive Pap-only testing (versus receiving co-testing). Follow-up from abnormal results was low for all groups (72.5%) but highest among Hispanic participants (78.8%, p<0.001). CONCLUSIONS: In a large cohort receiving care across 3 diverse healthcare settings, cervical cancer screening and follow-up were below 80% coverage targets. Lower screening for Black patients was attenuated by controlling for insurance and site of care, underscoring the role of systemic inequity. In addition, it is crucial to improve follow-up after abnormalities are identified, which was low for all populations.

Motivational Interviewing Counseling to Increase Endocrine Therapy Adherence in Diverse Patients.

BACKGROUND: Oral endocrine therapy (ET) is an inexpensive and effective therapy for hormone receptor-positive (HR+) breast cancer that prevents recurrence but relies upon long-term adherence for up to ten years. More than 80% of breast cancer patients have an HR+ phenotype and are candidates for ET, but approximately half discontinue or become non-adherent by five years. ET underuse is more prevalent in Black and young (<50 yrs) women, which may contribute to outcome disparities in these groups. The objective of this study was to evaluate the feasibility, acceptability, and utility of a patient-centered counseling intervention to enhance ET adherence, with a focus on the needs of Black and younger women. METHODS: We conducted a single-arm pilot study of a twelve-month motivational interviewing (MI) intervention consisting of five MI counseling sessions, an interactive workbook, a resource guide, and an educational video developed and revised with iterative patient and clinician input. The eligible participants were >18 years old, English speaking, and with stage I-III HR+ breast cancer. Participants were recruited across a large academic medical center and four community sites. Feasibility and acceptability were assessed by measures of participant recruitment, retention, session participation, and patient-reported satisfaction. ET adherence at 12 months was assessed by self-report and medication event monitoring system (MEMS) caps using a continuous measure of the proportion of days covered (PDC) as well as a dichotomous measure of the optimal adherence, defined as >80% PDC. RESULTS: Forty-two women initiated the intervention, of whom thirty-five participants (83%) completed outcome assessments at 12 months, including thirteen Black and twenty-two non-Black participants. The average participant age was 54.8 years (range: 25-73). Overall, 97% completed at least three MI sessions and 83% completed at least four sessions. Participant retention and satisfaction were high, particularly among Black women. Self-reported adherence at 12 months was 88% overall (100% in Black women and 81% in non-Black women). The majority of women also achieved 80% of days adherent using MEMS caps, with a greater adherence in Black women. CONCLUSIONS: This study demonstrates the feasibility, acceptability, and early promise of the effectiveness of an MI counseling-based intervention to promote ET adherence and prevent breast cancer recurrence in diverse populations.

Adherence to Adjuvant Endocrine Therapy and Survival Among Older Women with Early-Stage Hormone Receptor-Positive Breast Cancer.

BACKGROUND AND OBJECTIVE: Although improving adherence to adjuvant endocrine therapies (AETs) is critical to ensure better patient outcomes, the evidence is still lacking on differences in 5-year AET adherence trajectories. This study aimed to estimate the time trend of adherence by the type of individual AET and the association of adherence to AETs with overall survival among older women with hormone receptor-positive breast cancer. METHODS: This study used the Surveillance, Epidemiology, and End Results-Medicare database 2006-2016. We included women aged ≥ 65 years with newly diagnosed hormone receptor-positive breast cancer and who had initiated AET (anastrozole, letrozole, exemestane, or tamoxifen). Adherence to AETs was defined as the proportion of days covered that was calculated for the follow-up period (5 years). The overall survival time was defined as the time from the date of AET initiation to death. The linear mixed models with repeated measures were used to estimate the changes in adherence to AETs. The Cox proportional hazard model was used to assess the relationships (hazard ratio [HR] and 95% confidence interval [CI]) between adherence to AETs and death. RESULTS: A total of 11,617 patients were included. Anastrozole was the most commonly used (n = 6,908), followed by letrozole (n = 2,586), tamoxifen (n = 1,750), and exemestane (n = 373). The mean (standard deviation) of proportion of days covered for 5 years was 57.4 (34.6), indicating the highest proportion of days covered in the anastrozole group [61.1 (34.1)] and the lowest proportion of days covered in the exemestane group [44.0 (35.1)]. Overall, adherence to AET decreased over the 5-year follow-up period in all AET groups, but the decrease in the tamoxifen group was steeper (42.3% decreased) compared with other AETs. Anastrozole, letrozole, and exemestane groups were associated with a lower risk of death compared with the tamoxifen group (HR = 0.80, 95% CI 0.71-0.89 for anastrozole; HR = 0.82, 95% CI 0.72-0.93 for letrozole; HR = 0.82, 95% CI 0.63-1.07 for exemestane). CONCLUSIONS: Patients who initiated with tamoxifen had a steeper decrease in adherence over the 5 years compared with anastrozole, letrozole, and exemestane groups. Furthermore, higher adherence was associated with a decreased risk of mortality. Physicians should be cognizant of decreasing adherence over time and choose effective treatment options with minimal side-effect profiles to better support adherence by patients with breast cancer.

Understanding the role of access in Hispanic cancer screening disparities.

BACKGROUND: Hispanic populations in the United States experience numerous barriers to care access. It is unclear how cancer screening disparities between Hispanic and non-Hispanic White individuals are explained by access to care, including having a usual source of care and health insurance coverage. METHODS: A secondary analysis of the 2019 National Health Interview Survey was conducted and included respondents who were sex- and age-eligible for cervical (n = 8316), breast (n = 6025), or colorectal cancer screening (n = 11,313). The proportion of ever screened and up to date for each screening type was compared.  Regression models evaluated whether controlling for reporting a usual source of care and type of health insurance (public, private, none) attenuated disparities between Hispanics and non-Hispanic White individuals. RESULTS: Hispanic individuals were less likely than non-Hispanic White individuals to be up to date with cervical cancer screening (71.6% vs. 74.6%) and colorectal cancer screening (52.9% vs. 70.3%), but up-to-date screening was similar for breast cancer (78.8% vs. 76.3%). Hispanic individuals (vs. non-Hispanic White) were less likely to have a usual source of care (77.9% vs. 86.0%) and more likely to be uninsured (23.6% vs. 7.1%). In regressions, insurance fully attenuated cervical cancer disparities. Controlling for both usual source of care and insurance type explained approximately half of the colorectal cancer screening disparities (adjusted risk difference: -8.3 [-11.2 to -4.8]). CONCLUSION: Addressing the high rate of uninsurance among Hispanic individuals could mitigate cancer screening disparities. Future research should build on the relative successes of breast cancer screening and investigate additional barriers for colorectal cancer screening. PLAIN LANGUAGE SUMMARY: This study uses data from a national survey to compare cancer screening use those who identify as Hispanic with those who identify as non-Hispanic White. Those who identify as Hispanic are much less likely to be up to date with colorectal cancer screening than those who identify as non-Hispanic White, slightly less likely to be up to date on cervical cancer screening, and similarly likely to receive breast cancer screening. Improving insurance coverage is important for health equity, as is further exploring what drives higher use of breast cancer screening and lower use of colorectal cancer screening.

Many hops, many stops: care-seeking "loops" for diabetes and hypertension in three urban informal settlements in the Mumbai Metropolitan Region.

Background: The burden of Non-Communicable Diseases (NCDs) in urban informal settlements across Lower and Middle Income Countries is increasing. In recognition, there has been interest in fine-tuning policies on NCDs to meet the unique needs of people living in these settlements. To inform such policy efforts, we studied the care-seeking journeys of people living in urban informal settlements for two NCDs-diabetes and hypertension. The study was done in the Mumbai Metropolitan Region, India. Methods: This qualitative study was based on interviews with patients having diabetes and hypertension, supplemented by interactions with the general community, private doctors, and public sector staff. We conducted a total of 47 interviews and 6 Focus Group Discussions. We synthesized data thematically and used the qualitative software NVivo Version 10.3 to aid the process. In this paper, we report on themes that we, as a team, interpreted as striking and policy-relevant features of peoples' journeys. Results: People recounted having long and convoluted care-seeking journeys for the two NCDs we studied. There were several delays in diagnosis and treatment initiation. Most people's first point of contact for medical care were local physicians with a non-allopathic degree, who were not always able to diagnose the two NCDs. People reported seeking care from a multitude of healthcare providers (public and private), and repeatedly switched providers. Their stories often comprised multiple points of diagnosis, re-diagnosis, treatment initiation, and treatment adjustments. Advice from neighbors, friends, and family played an essential role in shaping the care-seeking process. Trade-offs between saving costs and obtaining relief from symptoms were made constantly. Conclusion: Our paper attempts to bring the voices of people to the forefront of policies on NCDs. People's convoluted journeys with numerous switches between providers indicate the need for trusted "first-contact" points for NCD care. Integrating care across providers-public and private-in urban informal settlements-can go a long way in streamlining the NCD care-seeking process and making care more affordable for people. Educating the community on NCD prevention, screening, and treatment adherence; and establishing local support mechanisms (such as patient groups) may also help optimize people's care-seeking pathways.

pMTL60000: A modular plasmid vector series for Parageobacillus thermoglucosidasius strain engineering.

Parageobacillus thermoglucosidasius is a promising chassis for producing chemicals and fuels. Here we designed, built and tested the pMTL60000 modular plasmids containing standardised Gram-positive and Gram-negative replicons, selectable markers and application-specific modules. The pMTL60000 modular plasmids were characterised with regard to transformation efficiency, segregational stability, copy number and compatibility.

Assessment of US Preventive Services Task Force Guideline-Concordant Cervical Cancer Screening Rates and Reasons for Underscreening by Age, Race and Ethnicity, Sexual Orientation, Rurality, and Insurance, 2005 to 2019.

Importance: Cervical cancer screening rates are suboptimal in the US. Population-based assessment of reasons for not receiving screening is needed, particularly among women from historically underserved demographic groups. Objective: To estimate changes in US Preventive Service Task Force guideline-concordant cervical cancer screening over time and assess the reasons women do not receive up-to-date screening by sociodemographic factors. Design, Setting, and Participants: This pooled population-based cross-sectional study used data from the US National Health Interview Survey from 2005 and 2019. A total of 20 557 women (weighted, 113.1 million women) aged 21 to 65 years without previous hysterectomy were included. Analyses were conducted from March 30 to August 19, 2021. Exposures: Sociodemographic factors, including age, race and ethnicity, sexual orientation, rurality of residence, and health insurance type. Main Outcomes and Measures: Primary outcomes were US Preventive Services Task Force guideline-concordant cervical cancer screening rates and self-reported primary reasons for not receiving up-to-date screening. For 2005, up-to-date screening was defined as screening every 3 years for women aged 21 to 65 years. For 2019, up-to-date screening was defined as screening every 3 years with a Papanicolaou test alone for women aged 21 to 29 years and screening every 3 years with a Papanicolaou test alone or every 5 years with high-risk human papillomavirus testing or cotesting for women aged 30 to 65 years. Population estimation included sampling weights. Results: Among 20 557 women (weighted, 113.1 million women) included in the study, most were aged 30 to 65 years (16 219 women; weighted, 86.3 million women [76.3%]) and had private insurance (13 571 women; weighted, 75.8 million women [67.0%]). With regard to race and ethnicity, 997 women (weighted, 6.9 million women [6.1%]) were Asian, 3821 women (weighted, 19.5 million women [17.2%]) were Hispanic, 2862 women (weighted, 14.8 million women [13.1%]) were non-Hispanic Black, 12 423 women (weighted, 69.0 million women [61.0%]) were non-Hispanic White, and 453 women (weighted, 3.0 million women [2.7%]) were of other races and/or ethnicities (including Alaska Native and American Indian [weighted, 955 000 women (0.8%)] and other single and multiple races or ethnicities [weighted, 2.0 million women (1.8%)]). In 2019, women aged 21 to 29 years had a significantly higher rate of overdue screening (29.1%) vs women aged 30 to 65 years (21.1%; P < .001). In both age groups, the proportion of women without up-to-date screening increased significantly from 2005 to 2019 (from 14.4% to 23.0%; P < .001). Significantly higher rates of overdue screening were found among those of Asian vs non-Hispanic White race and ethnicity (31.4% vs 20.1%; P = .01), those identifying as LGBQ+ (gender identity was not assessed because of a small sample) vs heterosexual (32.0% vs 22.2%; P < .001), those living in rural vs urban areas (26.2% vs 22.6%; P = .04), and those without insurance vs those with private insurance (41.7% vs 18.1%; P < .001). The most common reason for not receiving timely screening across all groups was lack of knowledge, ranging from 47.2% of women identifying as LGBQ+ to 64.4% of women with Hispanic ethnicity. Previous receipt of a human papillomavirus vaccine was not a primary reason for not having up-to-date screening (<1% of responses). From 2005 to 2019, among women aged 30 to 65 years, lack of access decreased significantly as a primary reason for not receiving screening (from 21.8% to 9.7%), whereas lack of knowledge (from 45.2% to 54.8%) and not receiving recommendations from health care professionals (from 5.9% to 12.0%) increased significantly. Conclusions and Relevance: This cross-sectional study found that cervical cancer screening that was concordant with US Preventive Services Task Force guidelines decreased in the US between 2005 and 2019, with lack of knowledge reported as the biggest barrier to receiving timely screening. Campaigns addressing patient knowledge and provider communication may help to improve screening rates, and cultural adaptation of interventions is needed to reduce existing disparities.

Potential effectiveness of a therapeutic HPV intervention campaign in Uganda.

Cervical cancer is a major source of morbidity and mortality in Uganda. In addition to prophylactic HPV vaccination, secondary prevention strategies are needed to reduce cancer burden. We evaluated the potential cancer reductions associated with a hypothetical single-contact therapeutic HPV intervention-with 70% coverage and variable efficacy [30%-100%]-using a three-stage HPV modeling framework reflecting HPV and cervical cancer burden in Uganda. In the reference case, we assumed prophylactic preadolescent HPV vaccination starting in 2020 with 70% coverage. A one-time therapeutic intervention targeting 35-year-old women in 2025 (not age-eligible for prophylactic vaccination) averted 1801 cervical cancers per 100 000 women over their lifetime (100% efficacy) or 533 cancers per 100 000 (30% efficacy). Benefits were considerably smaller in birth cohorts eligible for prophylactic HPV vaccination (768 cases averted per 100 000 at 100% efficacy). Evaluating the population-level impact over 40 years, we found introduction of a therapeutic intervention in 2025 with 100% efficacy targeted annually to 30-year-old women averted 139 000 incident cervical cancers in Uganda. This benefit was greatly reduced if efficacy was lower (30% efficacy; 41 000 cases averted), introduction was delayed (2040 introduction; 72 000 cases averted) or both (22 000 cases averted). We demonstrate the potential benefits of a single-contact HPV therapeutic intervention in a low-income setting, but show the importance of high therapeutic efficacy and early introduction timing relative to existing prophylactic programs. Reduced benefits from a less efficacious intervention may be somewhat offset if available within a shorter time frame.

Reducing Poverty-Related Disparities in Cervical Cancer: The Role of HPV Vaccination.

BACKGROUND: Near elimination of cervical cancer in the United States is possible in coming decades, yet inequities will delay this achievement for some populations. We sought to explore the effects of human papillomavirus (HPV) vaccination on disparities in cervical cancer incidence between high- and low-poverty U.S. counties. METHODS: We calibrated a dynamic simulation model of HPV infection to reflect average counties in the highest and lowest quartile of poverty (percent of population below federal poverty level), incorporating data on HPV prevalence, cervical cancer screening, and HPV vaccination. We projected cervical cancer incidence through 2070, estimated absolute and relative disparities in incident cervical cancer for high- versus low-poverty counties, and compared incidence with the near-elimination target (4 cases/100,000 women annually). RESULTS: We estimated that, on average, low-poverty counties will achieve near-elimination targets 14 years earlier than high-poverty counties (2029 vs. 2043). Absolute disparities by county poverty will decrease, but relative differences are estimated to increase. We estimate 21,604 cumulative excess cervical cancer cases in high-poverty counties over the next 50 years. Increasing HPV vaccine coverage nationally to the Healthy People 2020 goal (80%) would reduce excess cancer cases, but not alter estimated time to reach the near-elimination threshold. CONCLUSIONS: High-poverty U.S. counties will likely be delayed in achieving near-elimination targets for cervical cancer and as a result will experience thousands of potentially preventable cancers. IMPACT: Alongside vaccination efforts, it is important to address the role of social determinants and health care access in driving persistent inequities by area poverty.

Exercise Intervention: A Pilot Study to Assess the Feasibility and Impact on Cancer-Related Fatigue and Quality of Life Among Patients With High-Grade Glioma.

BACKGROUND: Cancer-related fatigue (CRF) is a challenging symptom, often compromising quality of life (QOL) and hindering physical activity among patients with cancer. OBJECTIVES: This 18-month pilot study assessed the feasibility to recruit and retain participants with high-grade glioma into a 10-week exercise intervention and evaluated the effects on CRF and QOL. METHODS: Participants were enrolled into the usual care, education, or exercise group based on time of enrollment and radiation treatment location. Feasibility was determined by accrual and retention rates. Fatigue and QOL were assessed at weeks 0, 3, and 10. Descriptive statistics and percentage change were used for pre-/post-test differences. FINDINGS: Exercise participants experienced less fatigue and improved QOL as compared to the usual care and education groups, suggesting that exercise favorably affects clinical outcomes and is feasible among patients with high-grade glioma.
