Racial/ethnic and socioeconomic disparities in mortality among women diagnosed with cervical cancer in New York City, 1995-2006

The relationship between household income and prognosis of patients with cervical adenocarcinoma in the United States: A retrospective cohort study based on the SEER database

OBJECTIVE

To investigate the association between household income and overall survival (OS) of patients with cervical adenocarcinoma.

METHODS

We conducted a retrospective cohort study involving participants selected from the Surveillance, Epidemiology, and End Results (SEER) database. Data were collected on various variables, including demographic variables such as median household income and clinicopathological characteristics for all participants. Cox regression analysis was utilized to examine the association between household income and OS. Subgroup analysis, sensitivity analysis, and E-value were used to further confirm the association.

RESULTS

A total of 2217 patients were included in the study. Compared with low-income (<$35,000-$54,999), middle-income (55,000-$69,999) or high-income (≥$70,000) was significantly associated with a higher 5-year OS (70.8 %, 58.7 % vs 50 %) in patients with cervical adenocarcinoma. The HR was 0.49, 95 % CI 0.41-0.58, p < 0.001 and 0.66 (0.55-0.78), p < 0.001 respectively, in the unadjusted model. After adjustment for potential confounders, the results were similar (adjusted HR 0.54 (0.45-0.65), p < 0.001) and 0.79 (0.66-0.94), p = 0.01), respectively. This significant association was also present in the various adjusted models. Subgroup and sensitivity analyses suggested that the relationship remained robust and reliable. The E-value analysis indicated robustness to unmeasured confounding. There was evidence of an interaction between age at diagnosis, race, primary site, tumor grade, T, N, M, or Scope Reg LN Sur, and household income on increasing the 5-year OS of cervical adenocarcinoma.

CONCLUSIONS

Our study found that middle or high household income was significantly associated with a better 5-year OS compared with low household income in patients with cervical adenocarcinoma.

The interaction between social determinants of health and cervical cancer survival: A systematic review

OBJECTIVE

This systematic review aimed to investigate what are the most relevant social determinants of health (SDH), how they are measured, how they interact among themselves and what is their impact on the outcomes of cervical cancer patients.

METHODS

Search was performed in PubMed, Scopus, Web of Science, Embase, Cochrane, and Google Scholar databases from January 2001 to September 2022. The protocol was registered at PROSPERO (CRD42022346854). We followed the PICOS strategy: Population- Patients treated for cervical cancer in the United States; Intervention - Any SDH; Comparison- None; Outcome measures- Cancer treatment outcomes related to the survival of the patients; Types of studies- Observational studies. Two reviewers extracted the data following the PRISMA guidelines. Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies was used for risk of bias (ROB) assessment.

RESULTS

Twenty-four studies were included (22 had low and 2 had moderate ROB). Most manuscripts analyzed data from public registries (83.3%) and only one SDH (54.17%). The SDH category of Neighborhood was not included in any study. Although the SDH were measured differently across the studies, not being married, receiving treatment at a low-volume hospital, and having public insurance (Medicaid or Medicare) or not being insured was associated with shorter survival of cervical cancer patients in most studies.

CONCLUSIONS

There is a deficit in the number of studies comprehensively assessing the impact of SDH on cervical cancer treatment-related outcomes. Marital status, hospital volume and health insurance status are potential predictors of worse outcome.

Critical analyses of Latina mortality: disentangling the heterogeneity of ethnic origin, place, nativity, race, and socioeconomic status

Despite the significant body of research on social determinants of health (SDH) and mortality, limited knowledge is available on the epidemiology of aggregated Latino health overall, and by women and subgroups. In population health studies, U.S. Latinos often are considered a monolithic population and presented as an aggregate, obscuring the diversity and variations within and across Latino subgroups, contributing to missed opportunities to identify SDH of health outcomes, and limiting the understanding of health differences. Given diverse environmental, racial, class, and geographic factors, a specific focus on women facilitates a more in-depth view of health disparities. This paper provides a scoping review of current gaps in research that assesses the relationships between SDH and mortality rates for the five leading causes of chronic-disease related deaths among Latinas by ethnic origin, place, race, and SES. We analyzed 2020 national mortality statistics from the CDC WONDER Online database jointly with reviews of empirical articles on Latina health, employing the EBSCOhost MEDLINE databases. These findings challenge the phenomenon of the Hispanic paradox that identified Latinos as a relatively healthy population compared to non-Hispanic White populations despite their lower economic status. The findings confirm that prior research on Latino women had methodological limitations due to the exclusion of SDH and an overemphasis on culturalist perspectives, while overlooking the critical role of socioeconomic impacts on health. Findings indicate major knowledge gaps in Latina mortality by SDH and subgroups that may undermine surveillance efforts and treatment efficacy. We offer forward-looking recommendations to assure the inclusion of key SDH associated with Latina mortality by subgroup as essential to inform future studies, intervention programs, and health policy.

Race and Ethnicity Disparities in Cardiovascular and Cancer Mortality: the Role of Socioeconomic Status-a Systematic Review and Meta-analysis

To clarify the role of socioeconomic status (SES) in cardiovascular and cancer mortality disparities observed between Black, Hispanic, and Asian compared to White adults, we conducted a meta-analysis of the longitudinal research in the USA. A PubMed, Ovid Medline, Web of Science, and EBSCO search was performed from January 1995 to May 2023. Two authors independently screened the studies and conducted risk assessments, with conflicts resolved via consensus. Studies were required to analyze mortality data using Cox proportional hazard regression. Random-effects models were used to pool hazard ratios (HR) and reporting followed PRISMA guidelines. Twenty-two studies with cardiovascular mortality (White and Black (n = 22), Hispanic (n = 7), and Asian (n = 3) adults) and twenty-three with cancer mortality endpoints (White and Black (n = 23), Hispanic (n = 11), and Asian (n = 10) adults) were included. The meta-analytic sample for cardiovascular mortality endpoints was 6,199,049 adults (White = 4,891,735; Black = 935,002; Hispanic = 295,623; Asian = 76,689), while for cancer-specific mortality endpoints was 7,745,180 adults (White = 5,988,392; Black= 1,070,447; Hispanic= 484,848; Asian = 201,493). Median follow-up was 10 and 11 years in cohorts with cardiovascular and cancer mortality endpoints, respectively. Adjustments for SES attenuated the higher risk for cardiovascular (HR, 1.46; 95% CI, 1.30-1.64) and cancer mortality (HR, 1.35; 95% CI, 1.32-1.38) of Black compared to White adults by 25% (HR, 1.21; 95% CI, 1.15-1.28) and 19% (HR, 1.16; 95% CI, 1.13-1.18), respectively. However, the Hispanic cardiovascular (HR, 0.79; 95% CI, 0.73-0.85) and Asian cancer mortality (HR, 0.81; 95% CI, 0.76-0.86) advantage were independent of SES. These findings emphasize the need to develop strategies focused on SES to reduce cardiovascular and cancer mortality in Black adults.

Patient-Provider Health Communication Strategies: Enhancing HPV Vaccine Uptake among Adolescents of Color

Cervical cancer remains a public health issue in the United States, particularly among stigmatized racial and ethnic populations. The human papillomavirus (HPV) vaccine has been clinically proven to prevent cervical cancers, and other HPV-associated cancers, among men and women. However, HPV vaccine uptake is suboptimal; only 55% of adolescents complete the two-dose series by age 15. Past research has shown that provider HPV vaccine communication for people of marginalized races/ethnicities is subpar. This article focuses on provider communication strategies to promote HPV vaccine uptake effectively and equitably. The authors reviewed the literature on evidence-based patient-provider HPV vaccine communication techniques to create a set of communication language providers could use and avoid using to enhance HPV vaccine acceptance and uptake among adolescents of marginalized racial and ethnic groups. Evidence has shown that information and the manner of dissemination are critical for influencing HPV vaccine uptake. These communication strategies must be suited to the context of the targeted population, and the message content can be broadly categorized into source, content, and modality. Strategies to improve patient-provider communication among adolescents of color using source, modality, and content include the following: (1) Source: increase provider self-efficacy to provide the recommendation, building rapport between providers and parents; (2) Content: persistent, forceful language with minimal acquiescence should be employed, reframing the conversation focus from sex to cancer; and (3) Modality: use multiple vaccine reminder modalities, and work with the community to culturally adapt the vaccination language. Utilizing effective behavior-change communication adapted for adolescents of color can reduce missed opportunities for HPV prevention, potentially decreasing racial and ethnic disparities in HPV-related morbidity and mortality.

Racial/Ethnic Disparities in Cervical Cancer Stage at Diagnosis: Mediating Effects of Neighborhood-level Socioeconomic Deprivation

BACKGROUND

Mortality from cervical cancer has declined steadily in the United States over the past several decades due to widespread screening for precancerous and early-stage cervical cancer (ECC), which are significantly easier to treat compared with late-stage cervical cancer (LCC). Unequal screening access continues to cause significant racial/ethnic disparities in cervical cancer diagnosis stage. This study examined the underlying role of neighborhood-level socioeconomic disadvantage as a potential mediator of the association between race/ethnicity and cervical cancer diagnosis stage.

METHODS

We analyzed Texas Cancer Registry data for cervical cancer cases diagnosed among women ages 18 or older from 2010 to 2018. We performed causal mediation analyses of the association between race/ethnicity and cervical cancer stage at diagnosis mediated by neighborhood-level socioeconomic disadvantage.

RESULTS

Of the 9,192 women with cervical cancer, 4,720 (51.3%) had LCC at diagnosis. Compared with non-Hispanic white (NHW) women (106.13, standard deviation (SD) = 13.32), non-Hispanic Black (NHB; 111.46, SD = 9.55) and Hispanic (112.32, SD = 9.42) women had higher area deprivation index (ADI) and had greater odds of LCC diagnosis [total effects: adjusted odds ratios (AOR) = 1.29 (95% CI, 1.11-1.46) and AOR 1.14 (95% CI, 1.03-1.25), respectively]. Approximately 34.7% and 71.6% of the disparity in LCC diagnosis were attributable to higher neighborhood socioeconomic disadvantage among NHB and Hispanic women, respectively.

CONCLUSIONS

LCC disparity varied by race/ethnicity and was partly attributable to neighborhood disadvantage. The disparity among Hispanic women due to neighborhood deprivation was twice as high among NHB women.

IMPACT

Findings may be used to develop targeted race- and place-specific interventions to improve cancer care equity.

A Randomized Controlled Trial to Increase Cancer Screening and Reduce Depression Among Low-Income Women

Low-income women of color receive fewer cancer screenings and have higher rates of depression, which can interfere with cancer screening participation. This study assessed the comparative effectiveness of two interventions for improving colorectal, breast, and cervical cancer screening participation and reducing depression among underserved women in Bronx, NY, with depression. This comparative effectiveness randomized controlled trial (RCT) with assessments at study entry, 6, and 12 months utilized an intent-to-treat statistical approach. Eligible women were aged 50 to 64, screened positive for depression, and were overdue for ≥ 1 cancer screening (colorectal, breast, and/or cervical). Participants were randomized to a collaborative depression care plus cancer screening intervention (CCI + PCM) or cancer screening intervention alone (PCM). Interventions were telephone-based, available in English or Spanish, delivered over 12 months, and facilitated by a skilled care manager. Cancer screening data were extracted from electronic health records. Depression was measured with a validated self-report instrument (PHQ-9). Seven hundred fifty seven women consented and were randomized (CCI + PCM, n = 378; PCM, n = 379). Analyses revealed statistically significant increases in up-to-date status for all three cancer screenings; depression improved in both intervention groups. There were no statistically significant differences between the interventions in improving cancer screening rates or reducing depression. CCI and PCM both improved breast, cervical, and colorectal cancer screening and depression in clinical settings in underserved communities; however, neither intervention showed an advantage in outcomes. Decisions about which approach to implement may depend on the nature of the practice and alignment of the interventions with other ongoing priorities and resources.

Prevalence and Treatment of Vulvar Cancer From 2014-2018: A Nationwide Population-Based Study in Korea

BACKGROUND

Vulvar cancer is one of the rare gynecologic malignancies. Despite the recent increasing trend of vulvar cancer in western countries due to the increased infection of human papillomavirus, there has been no study for population-based incidence of vulvar cancer in Korea. We aimed to investigate the prevalence and treatment of vulvar cancer in South Korea between 2014 and 2018.

METHODS

Data from patients diagnosed and treated with vulvar cancer between 2014 and 2018 were obtained from the Health Insurance Review and Assessment Service/National Inpatient Sample (National In-Patient Sample) in South Korea.

RESULTS

A total of 4,636,542 women were identified through the HIRA-NIS database from 2014 to 2018, of which 259 patients were diagnosed and treated for vulvar cancer. The mean age diagnosed with vulvar cancer was 62.82 (± 14.30) years in 2014, 64.19 (± 16.79) years in 2015, and 67.40 (± 14.41) years in 2016. In terms of treatment modalities, the most frequent treatment was surgery only without chemotherapy or radiation therapy. In the age-specific prevalence analysis, vulvar cancer was the most prevalent among those over 70 years old. According to multiple regression analysis, patients' age was significantly associated with the prevalence of vulvar cancer. Vulvar cancer was more prevalent in women with low socioeconomic status (SES) compared to those with high SES in 2018 (OR, 4.242; P < 0.001).

CONCLUSION

Considering the high prevalence of vulvar cancer in the elderly, it is necessary to establish a new strategy for early screening and treatment.

Health services related factors affecting the pap smear services in Fiji: a qualitative study

BACKGROUND

Cervical cancer is the thirdly vast usual cause of cancer in women, and the second vast majority cause of death among women aged 14 to 44 years, both in developed and developing countries. This paper aims to explore the perception of women and Health Care Workers (HCWs) about health care related factors affecting the Pap smear services among women who are screened in the Women Wellness Centre (WWC) in Suva, Fiji.

METHODS

This study used a qualitative method in July-September 2019 in which women screened for cervical cancer used in-depth interviews whereas HCWs used Focus Group Discussion (FGD) in WWC in Suva, Fiji. This study used purposive maximum variation sampling where participants are selected according to the inclusion and exclusion criteria. Semi-structured open ended questionnaires were used to collect the data among participants. Data coding was done until theoretical saturation was reached. Thematic analysis was used and all the text has been coded, themes were abstracted from the coded text segments.

RESULTS

A total of 20 women screened for cervical cancer and 5 HCWs were present during the duration of the study. Health care system was a factor recognized by both groups to have been a cause for the hindrance of cervical screening. There were 8 themes identified from the study, 3 themes from the women screened for cervical cancer and 5 from HCWs. Nearly all the participants reported about the compromised of cervical cancer screening services delivery because of factors such as lack of equipment and supplies, shortage of staff, long distances to health facilities, turnaround time and delay of results which affect the uptake of cervical cancer screening services.

CONCLUSION

While improvement has been made in the distribution of cervical cancer screening in WWC, a number of barriers and factors affect service uptake and delivery. Investments to be made in order to address the identified barriers such as turnaround time, long distances to health facilities, shortage of supplies and staff in order to improve uptake of cervical cancer screening services.

Racial-Ethnic Comparison of Guideline-Adherent Gynecologic Cancer Care in an Equal-Access System

OBJECTIVE

To compare receipt of National Comprehensive Cancer Network Guideline-adherent treatment for gynecologic cancers, inclusive of uterine, cervical, and ovarian cancer, between non-Hispanic White women and racial-ethnic minority women in the equal-access Military Health System.

METHODS

We accessed MilCanEpi, which links data from the Department of Defense Central Cancer Registry and Military Health System Data Repository administrative claims data, to identify a cohort of women aged 18-79 years who were diagnosed with uterine, cervical, or ovarian cancer between January 1, 1998, and December 31, 2014. Information on tumor stage, grade, and histology was used to determine which treatment(s) (surgery, chemotherapy, radiotherapy) was indicated for each patient according to the National Comprehensive Cancer Network Guidelines during the period of the data (1998-2014). We compared non-Hispanic Black, Asian, and Hispanic women with non-Hispanic White women in their likelihood to receive guideline-adherent treatment using multivariable logistic regression models given as adjusted odds ratios (aORs) and 95% CIs.

RESULTS

The study included 3,354 women diagnosed with a gynecologic cancer of whom 68.7% were non-Hispanic White, 15.6% Asian, 9.0% non-Hispanic Black, and 6.7% Hispanic. Overall, 77.8% of patients received guideline-adherent treatment (79.1% non-Hispanic White, 75.9% Asian, 69.3% non-Hispanic Black, and 80.5% Hispanic). Guideline-adherent treatment was similar in Asian compared with non-Hispanic White patients (aOR 1.18, 95% CI 0.84-1.48) or Hispanic compared with non-Hispanic White women (aOR 1.30, 95% CI 0.86-1.96). Non-Hispanic Black patients were marginally less likely to receive guideline-adherent treatment compared with non-Hispanic White women (aOR 0.73, 95% CI 0.53-1.00, P=.011) and significantly less likely to receive guideline-adherent treatment than either Asian (aOR 0.65, 95% CI 0.44-0.97) or Hispanic patients (aOR 0.56, 95% CI 0.34-0.92).

CONCLUSION

Racial-ethnic differences in guideline-adherent care among patients in the equal-access Military Health System suggest factors other than access to care contributed to the observed disparities.

The impact of socioeconomic deprivation on mortality in cervical cancer patients in Cornwall (England)

OBJECTIVES

To assess the association between risk factors, including socioeconomic deprivation, and mortality, recurrence and chemo- or radiation toxicity in cervical cancer patients.

METHODS

Retrospective study of cervical cancer patients diagnosed between January 2007 and July 2018. Patient characteristics and mortality data, including recurrence, were assessed, together with socioeconomic deprivation measures evaluated using the English Indices of Multiple Deprivation. Markov multi-state models were used to model mortality and recurrence, and logistic regression models were used to model chemo- or radiation toxicity.

RESULTS

Included were 243 women with a median age of 49 years. A total of 57 patients died (23%), of which 41 due to cervical cancer, and 21 (9%) had recurrent disease. Hazard ratios (HR) showed no evidence of association between socioeconomic deprivation and cancer-specific hazard of mortality from diagnosis or recurrence, hazard of mortality due to other causes or hazard of cancer recurrence. Furthermore, there was no evidence of association between socioeconomic deprivation and chemo- or radiation toxicity (bowel, bladder or vaginal stenosis).

CONCLUSIONS

No associations were found between socioeconomic deprivation and cancer mortality or recurrence in cervical cancer patients in the population of Cornwall. In addition, no association was found between socioeconomic deprivation and chemo- or radiation toxicity.

Regional inequalities in cervical cancer survival in Minas Gerais State, Brazil

BACKGROUND

Cervical cancer survival is marked by socioeconomic and demographic inequalities. We investigated differences in survival across health regions in Minas Gerais, Brazil, in cervical cancer patients who underwent treatment in the Brazilian Public Health System.

METHODS

From a database developed through probabilistic and deterministic linkage of data from information systems of the Brazilian Public Health System, we identified cervical cancer cases, diagnosed between 2002 and 2010, who underwent radiation and/or chemotherapy and lived in Minas Gerais, Brazil. Five-year overall and cause-specific survivals were estimated by the Kaplan-Meier method and compared using the log-rank test. We used extended Cox models to assess the relationship between the health region of residence and the overall and cause-specific death risk, adjusting for relevant variables.

RESULTS

We included 5613 patients with a median age of 55.0 years. Median follow-up time was 70.0 months. Five-year overall and cause-specific survivals were 56.3 % and 63.6 %, respectively. Across the 13 health regions, 5-year survival ranged from 46.6%-64.2% (p < 0.001) in the overall analysis and from 52.0% to 72.0% (p < 0.001) in the cause-specific analysis. Multivariate models revealed a significantly higher death risk for most health regions in comparison to the reference health region (Norte). Adjustment by age, tumor stage, comorbidity, treatment, travel time, and year of diagnosis had little effect on the association.

CONCLUSION

We found regional disparities in cervical cancer survival that persisted after relevant adjustments. Uneven regional provision of health services might be implicated in these disparities, affecting timely access to treatment for cervical cancer patients.

Integrating Cancer Screening and Mental Health Services in Primary Care: Protocol and Baseline Results of a Patient-Centered Outcomes Intervention Study

BACKGROUND

Low-income and minority women are significantly more likely to be diagnosed with preventable, late-stage cancers and suffer from depression than the general population. Intervention studies aiming to reduce depression to increase cancer screening among underserved minority women are sparse.

METHODS

This patient-centered outcomes trial compared Collaborative Care Intervention plus Cancer Prevention Care Management (CCI+PCM) versus PCM alone. Participants from six Federally Qualified Health Centers (FQHCs) were interviewed at baseline, 6-and 12-month follow-up to monitor adherence to screening guidelines, depressive symptoms, quality of life, barriers to screening, and other psychosocial and health-related variables.

RESULTS

Participants included 757 English-or Spanish-speaking women (ages 50-64) who screened positive for depression on the Patient Health Questionnaire (PHQ)-9 and were not up-to-date for breast, cervical, and/or colorectal cancer screening.

CONCLUSIONS

Study methodology and baseline participant characteristics are reported to contribute to the literature on evidence-based interventions for cancer screening among underserved, depressed women.

Cervical cancer sociodemographic and diagnostic disparities in Florida: a population-based study (1981-2013) by stage at presentation

Objective: Florida has one of the highest cervical cancer mortality rates and socioeconomically diverse populations in the United States. We used statewide population-based cancer registry data to assess disparities in cervical cancer stage at diagnosis. Design: Primary invasive adult female cervical cancer patients in the Florida Cancer Data Registry (1981-2013) were linked with 2000 United States Census data. Early (localized) and advanced (regional and distant) stage at diagnosis was assessed by age, race, ethnicity, neighborhood socioeconomic-, marital-, and smoking- status. Univariate and multivariable logistic regression models were fit to identify factors associated with the risk of advanced cervical cancer stage at diagnosis. Adjusted odds ratios (aOR) and corresponding 95% confidence intervals (95%CI) were calculated. Results: Of 18,279 women (mean_age 51.3 years old), most were non-Hispanic (83.5%), white (79.1%), middle-low neighborhood socioeconomic status (NSES) (34.7%), married (46.0%), and never smoked (56.0%). Higher odds of advanced stage was observed for blacks (aOR: 1.42, 95%CI: 1.30-1.55, p < 0.001) compared to whites, Hispanics (1.15, 1.06-1.25, p = 0.001) compared to non-Hispanics, and middle-low (1.13, 1.02-1.25, p = 0.02) and low NSES (1.42, 1.28-1.57, p < 0.001) compared to high NSES. Previously (1.30, 1.21-1.39, p < 0.001) and never married (1.37, 1.27-1.48, p < 0.001) had higher odds of presenting with advanced stage versus married women. Never smokers had decreased odds of presenting with advanced stage compared to women with history of (1.41, 1.32-1.52, p < 0.001) or current (1.29, 1.18-1.42, p < 0.001)smoking status. Conclusions: There are cancer disparities in women of black race, Hispanic ethnicity and of middle-low and lowest NSES in Florida. Evidence-based interventions targeting these vulnerable groups are needed.

Using Peer Health Educators to Conduct Community Level Surveillance of HPV Vaccination Status: Findings Among Women Who Live in Medically Underserved Areas of Chicago

Young women are key stakeholders in efforts to increase human papillomavirus (HPV) vaccination uptake. Community health workers who engage with young women can provide valuable information to inform intervention strategies to increase vaccine uptake. We aimed to determine HPV vaccination and sexually transmitted infection (STI) rates among urban women and to identify barriers to vaccination. A trained health educator collaborated with community-based organizations to host health education and STI testing sessions for women in Chicago, Illinois. Forty-nine sessions took place at 15 sites over two years. Each attendee met with the educator about sexual health and HPV vaccination, and completed a health survey. We used contingency tables and logistic regression to determine factors associated with HPV vaccination using the cross-sectional survey data. Of the 292 women who answered questions about history of HPV vaccination, the average age was 17 (SD 2.3) years old, 63% (n = 184) were African American, and 33% (n = 98) Hispanic. Only 13.4% (n = 39) previously received the vaccine, and 6.2% (n = 18) received two to three doses. After adjustment, prior HIV testing was associated with 4.6 times higher odds (95% CI 1.71, 12.53, p = 0.002) of being vaccinated compared to women without prior testing. Our study provides evidence that young African American and Hispanic women living in Chicago may have low HPV vaccination rates. Women who received prior STI testing (i.e., sought healthcare) were more likely to be vaccinated relative to their peers who did not, indicating that racial/ethnic or socioeconomic disparities may inhibit utilization of preventative services.

Declines in Vaccine-Type Human Papillomavirus Prevalence in Females Across Racial/Ethnic Groups: Data From a National Survey

PURPOSE

To monitor human papillomavirus (HPV) vaccine impact in the U.S., we evaluated quadrivalent vaccine (4vHPV)-type prevalence among females aged 14-34 years in the prevaccine (2003-2006) and vaccine (2013-2016) eras overall and by race/ethnicity in the National Health and Nutrition Examination Survey.

METHODS

We analyzed HPV DNA prevalence in self-collected cervicovaginal specimens, demographic characteristics, sexual behavior, and self-reported/parent-reported vaccination status. We compared prevaccine to vaccine era 4vHPV-type prevalence, using unadjusted and adjusted prevalence ratios (PR and aPR) and 95% confidence intervals (CIs). PRs were calculated by race/ethnicity (non-Hispanic white [NHW], non-Hispanic black [NHB], and Mexican American [MA]). Overall aPRs were adjusted for race/ethnicity, lifetime sex partners, and poverty.

RESULTS

Overall, 4,674 females had HPV typing results; 3,915 reported NHW, NHB, or MA race/ethnicity. Vaccination coverage of ≥1 dose was 53.9% among 14- to 19-year-olds (NHW 52.6%, NHB 58.1%, and MA 59.5%) and 51.5% among 20- to 24-year-olds (NHW 58.8%, NHB 45.0%, MA 33.8%). Among 14- to 19-year-olds, 4vHPV-type prevalence decreased overall (11.5% to 1.8%; aPR = .14 [CI: .08-.24]) and in NHW (PR = .14 [CI: .06-.29]), NHB (PR = .26 [CI: .12-.54]), and MA (PR = .13 [CI: .03-.53]). In 20- to 24-year-olds, 4vHPV-type prevalence decreased overall (18.5% to 5.3%; aPR = .29 [CI: .15-.56]) and in NHW (PR = .27 [CI: .11-.67]) and NHB (PR = .38 [CI: .18-.80]). No significant declines were observed in older age groups.

CONCLUSIONS

Within 10 years of vaccine introduction, 4vHPV-type prevalence declined 86% among 14- to 19-year-olds, with declines observed in NHW, NHB, and MA females, and 71% among 20- to 24-year-olds, with declines in NHW and NHB females. These extraordinary declines should lead to substantial reductions in HPV-associated cancers.

Hospitalization outcomes and racial disparities in cervical cancer patients: An analysis of the national inpatient sample data from 2002 to 2014

BACKGROUND

Little is known about outcomes in patients after being hospitalized for care of cancer or comorbid conditions and the disparity between African-American and White cervical cancer patients.

METHODS

Using the national inpatient sample (HCUP-NIS) database of the Healthcare Cost and Utilization Project between 2002-2014, we included 5217 African-American and 21,752 White patients hospitalized with a primary diagnosis of cervical cancer. We examined racial differences in hospitalization outcomes; length of stay (LOS) in hospital, mortality in hospital, post-operative complications in patients who underwent hysterectomy and discharge disposition. Patients were matched on age at primary diagnosis, insurance status, residential region, and median income of residential area, modified Deyo comorbidity index, stage of disease and treatment. Categorical outcomes were analyzed by conditional logistic regression accounting for matched study design and odds ratios (95%CI) were reported. LOS was analyzed using t-test and beta estimate for difference in means was reported.

RESULTS

The LOS was significantly lower for Whites compared to African-American cervical cancer patients when matched on demographic only (β=-0.41, p-value<0.0005, presentation + demographic (β=-0.41, p-value<0.0006) and treatment + presentation + demographic variables (β=-0.46, p-value<0.0001). White cervical cancer patients were commonly discharged to other intermediate nursing facility (OR = 1.30, 95%CI = 1.20-1.41, matched on demographic only; OR = 1.31, 95%CI = 1.21-1.43, matched on presentation + demographic; and OR = 1.32, 95%CI = 1.22-1.43), matched on treatment + presentation + demographic). Similar trends were seen in both older (≥65 years) and younger (<65 years) patients, when stratified by age.

CONCLUSION

Disparities in hospitalization outcomes in cervical patients are not observed when different characteristics of African-American and White cervical patients are accounted for and matched.

Racial/Ethnic Disparities in Mammogram Frequency Among Women With Intellectual Disability

Little information exists on the associations between intellectual disability (ID) and race/ethnicity on mammogram frequency. This study collected survey and medical record data to examine this relationship. Results indicated that Hispanic and Black women with ID were more likely than White women with ID to have mammograms every 2 years. Participants who live in a state-funded residence, were aged 50+, and had a mild or moderate level of ID impairment were more likely to undergo mammography compared to participants living with family or alone, were <50, and had severe ID impairment. Further research is needed to understand the mechanisms explaining disparities in mammograms between these racial/ethnic groups.

Disparities in Adherence to National Comprehensive Cancer Network Treatment Guidelines and Survival for Stage IB-IIA Cervical Cancer in California

OBJECTIVE

To evaluate the association of sociodemographic and hospital characteristics with adherence to National Comprehensive Cancer Network treatment guidelines for stage IB-IIA cervical cancer and to analyze the relationship between adherent care and survival.

METHODS

This is a retrospective population-based cohort study of patients with stage IB-IIA invasive cervical cancer reported to the California Cancer Registry from January 1, 1995, through December 31, 2009. Adherence to National Comprehensive Cancer Network guideline care was defined by year- and stage-appropriate surgical procedures, radiation, and chemotherapy. Multivariate logistic regression, Kaplan-Meier estimate, and Cox proportional hazard models were used to examine associations between patient, tumor, and treatment characteristics and National Comprehensive Cancer Network guideline adherence and cervical cancer-specific 5-year survival.

RESULTS

A total of 6,063 patients were identified. Forty-seven percent received National Comprehensive Cancer Network guideline-adherent care, and 18.8% were treated in high-volume centers (20 or more patients/year). On multivariate analysis, lowest socioeconomic status (adjusted odds ratio [OR] 0.69, 95% CI 0.57-0.84), low-middle socioeconomic status (adjusted OR 0.76, 95% CI 0.64-0.92), and Charlson-Deyo comorbidity score 1 or higher (adjusted OR 0.78, 95% CI 0.69-0.89) were patient characteristics associated with receipt of nonguideline care. Receiving adherent care was less common in low-volume centers (45.9%) than in high-volume centers (50.9%) (effect size 0.90, 95% CI 0.84-0.96). Death from cervical cancer was more common in the nonadherent group (13.3%) than in the adherent group (8.6%) (effect size 1.55, 95% CI 1.34-1.80). Black race (adjusted hazard ratio 1.56, 95% CI 1.08-2.27), Medicaid payer status (adjusted hazard ratio 1.47, 95% CI 1.15-1.87), and Charlson-Deyo comorbidity score 1 or higher (adjusted hazard ratio 2.07, 95% CI 1.68-2.56) were all associated with increased risk of dying from cervical cancer.

CONCLUSION

Among patients with early-stage cervical cancer, National Comprehensive Cancer Network guideline-nonadherent care was independently associated with increased cervical cancer-specific mortality along with black race and Medicaid payer status. Nonadherence was more prevalent in patients with older age, lower socioeconomic status, and receipt of care in low-volume centers. Attention should be paid to increase guideline adherence.

On surmounting the barriers to HPV vaccination: we can do better

The major impediment to increased human papillomavirus (HPV) vaccination coverage in young males and females is lack of health care provider recommendation. Despite its efficacy in preventing cervical cancer, HPV vaccination in females (49.5%) and males (37.5%) ages 13 through 17 falls well below the Centers for Disease Control and Prevention's (CDC) Healthy People 2020 target of 80% coverage. Parents' willingness to vaccinate their child has been shown to be much higher when physicians share personal vaccination decisions for their own children as well as what other parents have done at that particular clinic. Furthermore, the vaccine must be presented presumptively as a "bundle" along with the rest of the standard adolescent vaccine panel. Multiple exemplars presented including in several European countries, low-income countries and Rwanda, demonstrate that school-based health care systems dramatically increase vaccination coverage. Finally, acceptability for vaccination of males must improve by increasing provider recommendation and by presenting the HPV vaccine as a penile, anal and oropharyngeal cancer prevention therapy in males and not merely a vaccine to prevent cervical cancers in females. Paediatricians, obstetrician/gynaecologists and primary care physicians should consider these data as a call-to-action. Key messages   • Despite recent efforts in the US, only 49.5% of females and only 37.5% of males ages 13 through 17 have received all recommended HPV vaccine doses. These numbers fall well below the 80% target set forth by the Healthy People 2020 initiative.   • According to the CDC, if health care providers increase HPV vaccination rates in eligible recipients to 80%, it is estimated that an additional 53,000 cases of cervical cancer could be prevented during the lifetime of those younger than 12 years. Furthermore, for every year that the vaccination rate does not increase, an additional 4400 women will develop cervical cancer.   • First and foremost, healthcare providers (HCPs) must make a strong recommendation to vaccinate patients and these recommendations must become routine, including for males.   • It is clear that HPV vaccination rates improve significantly when vaccine administration occurs at designated, well-organized sites such as school-based vaccination programmes. Furthermore, HPV vaccination should be a high school requirement and offered in the standard adolescent vaccine panel as a bundle with Tdap and MenACWY vaccines in order to promote maximum adherence.   • Finally, research on immunogenicity and antibody titre longevity needs to be done in newborns. The HPV vaccine may be recommended in the newborn panel of vaccines to avoid any issues of sexualization and misplaced fears of sexual disinhibition, akin to the success of the Hepatitis B vaccine in the 1980s.   • The HPV vaccine is a vaccine against cancer and should be aggressively marketed as such. As healthcare providers, we need to make every effort to overcome barriers, real or perceived, to protecting our population from potential morbidity and mortality associated with this virus.

Mujer Sana, Familia Fuerte: The Effects of a Culturally-Relevant, Community-Based, <i>Promotores</i> Program to Increase Cervical Cancer Screening among Latinas

OBJECTIVE

Although cervical cancer can be prevented through screening and follow-up, Latinas' rate of Pap tests remains low due to knowledge gaps and cultural and attitudinal factors.

METHODS

This study used a single-group pre-/post-test design to evaluate the effectiveness of Mujer Sana, Familia Fuerte (Healthy Woman, Strong Family), an intervention intended to improve Latinas' cervical cancer prevention knowledge, attitudes, self-efficacy to obtain a Pap test, and intention to get tested. The intervention is delivered through a single session by promotores de salud, who use a culturally competent, linguistically appropriate toolkit. A total of 5,211 Latinas participated in the study.

RESULTS

The evaluation indicated that participants had increases in knowledge, positive attitudes, self-efficacy, and intention to test.

CONCLUSION

Latinas have a low rate of cervical cancer screening but a high rate of cervical cancer, and Mujer Sana, Familia Fuerte shows promise as a public health practice for use with this population.

Health Volunteerism and Improved Cancer Health for Latina and African American Women and Their Social Networks: Potential Mechanisms

Health volunteerism has been associated with positive health outcomes for volunteers and the communities they serve. This work suggests that there may be an added value to providing underserved populations with information and skills to be agents of change. The current study is a first step toward testing this hypothesis. The purpose is to identify how volunteerism may result in improved cancer health among Latina and African American women volunteers. A purposive sample of 40 Latina and African American female adults who had participated in cancer volunteerism in the past 5 years was recruited by community advocates and flyers distributed throughout community venues in San Diego, CA. This qualitative study included semi-structured focus groups. Participants indicated that volunteerism not only improved their health but also the health of their family and friends. Such perceptions aligned with the high rates of self-report lifetime cancer screening rates among age-eligible patients (e.g., 83-93 % breast; 90-93 % cervical; 79-92 % colorectal). Identified mechanisms included exposure to evidence-based information, health-protective social norms and support, and pressure to be a healthy role model. Our findings suggest that train-the-trainer and volunteer-driven interventions may have unintended health-protective effects for participating staff, especially Latina and African American women.

Standardized cancer incidence disparities in Upper Manhattan New York City neighborhoods: the role of race/ethnicity, socioeconomic status, and known risk factors

We examined the effects of race/ethnicity and neighborhood, a proxy of socioeconomic status, on cancer incidence in New York City neighborhoods: East Harlem (EH), Central Harlem (CH), and Upper East Side (UES). In this ecological study, Community Health Survey data (2002-2006) and New York State Cancer Registry incidence data (2007-2011) were stratified by sex, age, race/ethnicity, and neighborhood. Logistic regression models were fitted to each cancer incidence rate with race/ethnicity, neighborhood, and Community Health Survey-derived risk factors as predictor variables. Neighborhood was significantly associated with all cancers and 14 out of 25 major cancers. EH and CH residence conferred a higher risk of all cancers compared with UES (OR=1.34, 95% CI 1.07-1.68; and OR=1.39, 95% CI 1.12-1.72, respectively). The prevalence of diabetes and tobacco smoking were the largest contributors toward high cancer rates. Despite juxtaposition and similar proximity to medical centers, cancer incidence disparities persist among EH, CH, and UES neighborhoods. Targeted, neighborhood-specific outreach may aid in reducing cancer incidence rates.

Socioeconomic and Racial/Ethnic Disparities in Cancer Mortality, Incidence, and Survival in the United States, 1950-2014: Over Six Decades of Changing Patterns and Widening Inequalities

We analyzed socioeconomic and racial/ethnic disparities in US mortality, incidence, and survival rates from all-cancers combined and major cancers from 1950 to 2014. Census-based deprivation indices were linked to national mortality and cancer data for area-based socioeconomic patterns in mortality, incidence, and survival. The National Longitudinal Mortality Study was used to analyze individual-level socioeconomic and racial/ethnic patterns in mortality. Rates, risk-ratios, least squares, log-linear, and Cox regression were used to examine trends and differentials. Socioeconomic patterns in all-cancer, lung, and colorectal cancer mortality changed dramatically over time. Individuals in more deprived areas or lower education and income groups had higher mortality and incidence rates than their more affluent counterparts, with excess risk being particularly marked for lung, colorectal, cervical, stomach, and liver cancer. Education and income inequalities in mortality from all-cancers, lung, prostate, and cervical cancer increased during 1979-2011. Socioeconomic inequalities in cancer mortality widened as mortality in lower socioeconomic groups/areas declined more slowly. Mortality was higher among Blacks and lower among Asian/Pacific Islanders and Hispanics than Whites. Cancer patient survival was significantly lower in more deprived neighborhoods and among most ethnic-minority groups. Cancer mortality and incidence disparities may reflect inequalities in smoking, obesity, physical inactivity, diet, alcohol use, screening, and treatment.

Human papillomavirus-induced oropharyngeal cancer in Hispanics in the United States

OBJECTIVES/HYPOTHESIS

Determine disparities in survival outcome and clinical presentation between Hispanic and non-Hispanic white patients with human papillomavirus-positive oropharyngeal squamous cell carcinoma.

STUDY DESIGN

Retrospective clinical research.

METHODS

Clinical data on Hispanics and non-Hispanic white patients with diagnosis of human papillomavirus/p16-positive oropharyngeal squamous cell carcinoma were drawn from a tumor registry from the University of Miami Hospitals and Clinics from 2008 to 2014. Of 436 patients with oropharyngeal squamous cell carcinoma, 237 patents met inclusion criteria. Patient's age, gender, smoking history, alcohol history, race/ethnicity, tumor T stage, nodal N stage, and composite TNM stage were included in the analysis. Associations between race and other categorical variables were explored with χ² test or Fisher exact test where appropriate. Survival curves were generated using the Kaplan-Meier method.

RESULTS

Significant differences in clinical presentation was detected between Hispanic (N = 70) and non-Hispanic white (N = 167) patients. Hispanic human papillomavirus-positive oropharyngeal squamous cell carcinoma patients showed a higher proportion of women with disease, a higher proportion of patients presenting with tonsil rather than tongue base primary subsite cancer, and a higher proportion of patients who do not consume alcohol compared to non-Hispanic white human papillomavirus-positive oropharyngeal squamous cell carcinoma patients. A statistically significant survival difference between these two ethnic groups was not detected in the current dataset.

CONCLUSIONS

Unique differences in clinical presentations between Hispanic patients and non-Hispanic whites with human papillomavirus-positive oropharyngeal squamous cell carcinoma were detected. This may be the first study to report novel clinical presentation in Hispanic human papillomavirus-positive patients with oropharyngeal squamous cell carcinoma living in the United States.

Treatment Compliance and Outcomes for Women With Locoregionally Advanced Cervical Cancer Treated in a Safety Net Health System

OBJECTIVE

This study aims to assess treatment compliance among women undergoing definitive chemoradiation with weekly cisplatin for cervical cancer within a safety net health system and to quantify the impact of chemotherapy compliance on outcomes.

MATERIALS AND METHODS

All women who were treated for International Federation of Gynecology and Obstetrics stage IB2 to stage IVA cervical cancer between April 2008 and May 2014 were identified. Treatment delays were attributed to toxicity, comorbid conditions, or system issues, or categorized as patient-initiated. Disease-free survival and overall survival of women who received fewer than 6 versus 6 or more doses of weekly cisplatin 40 mg/m were compared using Kaplan-Meier analyses.

RESULTS

One hundred nineteen women (mean [SD] age, 48.5 [11.8] years) were identified. Most women (n = 112; 94.1%) completed definitive radiotherapy, requiring a mean (SD) of 56.5 (20.1) days. Sixty-four women (57.1%) completed definitive radiotherapy in 56 days or less. Only 44 women (36.4%) received 6 or more cycles of cisplatin. Of 122 delayed cycles, reasons for delay were as follows: grade 2 or higher toxicity (n = 70; 57.4%), medical comorbidity (n = 12; 9.8%), system issues (n = 9; 7.4%), and patient-initiated (n = 14; 11.5%). Multiple issues complicated treatment for 3 doses (2.5%). Reasons for delay were not documented in 14 doses (11.5%). Among patients who received 6 or more cycles, disease-free survival improved by 17.4 months (mean [SD], 61.1 [3.7] vs 43.7 [4.3] months, P = 0.002) and overall survival improved by 8.6 months (mean [SD], 68.7 [2.3] vs 60.1 [3.7] months, P = 0.011).

CONCLUSIONS

Higher rates of toxicity and psychosocial barriers to chemotherapy compliance adversely impact survival among women who seek care in low-resource settings. In our population, administration of all 6 cycles of cisplatin was necessary for optimal survival benefit. Future efforts to improve cervical cancer outcomes should address preventable reasons for treatment delays among underinsured or uninsured individuals.

Disparities in collaborative patient-provider communication about human papillomavirus (HPV) vaccination

BACKGROUND

Healthcare providers may vary their communications with different patients, which could give rise to differences in vaccination coverage. We examined demographic disparities in parental report of collaborative provider communication and implications for human papillomavirus (HPV) vaccination.

METHODS

Participants were 4,124 parents who completed the National Immunization Survey-Teen about daughters ages 13-17. We analyzed disparities in collaborative communication (mutual information exchange, deliberation, and decision) and whether they mediated the relationship between demographic characteristics and HPV vaccine initiation.

RESULTS

Half of parents (53%) in the survey reported collaborative communication. Poor, less educated, Spanish-speaking, Southern, and rural parents, and parents of non-privately insured and Hispanic adolescents, were least likely to report collaborative communication (all p<.05). These disparities in communication accounted for geographic variation in HPV vaccination, specifically, the higher rates of uptake in the Northeast versus the South (mediation z=2.31, p<.01) and in urban/suburban vs. rural areas (mediation z=2.87, p<.01). These disparities were also associated with vaccination among subgroups with relatively high coverage, minimizing what could have been even higher uptake among Hispanic compared to non-Hispanic white adolescents (mediation z=-3.04, p<.01) and non-privately versus privately insured adolescents (mediation z=-3.67, p<.001). Controlling for provider recommendation attenuated some of these associations (but all p<.10).

CONCLUSIONS

Collaborative communication showed widespread disparities, being least common among underserved groups. Collaborative communication helped account for differences-and lack of differences-in HPV vaccination among some subgroups of adolescent girls. Leveraging patient-provider communication, especially for underserved demographic groups, could improve HPV vaccination coverage.

An Ethical Justification for Expanding the Notion of Effectiveness in Vaccine Post-Market Monitoring: Insights from the HPV Vaccine in Canada

Health regulators must carefully monitor the real-world safety and effectiveness of marketed vaccines through post-market monitoring in order to protect the public's health and promote those vaccines that best achieve public health goals. Yet, despite the fact that vaccines used in collective immunization programmes should be assessed in the context of a public health response, post-market effectiveness monitoring is often limited to assessing immunogenicity or limited programmatic features, rather than assessing effectiveness across populations. We argue that post-market monitoring ought to be expanded in two ways to reflect a 'public health notion of post-market effectiveness', which incorporates normative public health considerations: (i) effectiveness monitoring should yield higher quality data and grant special attention to underrepresented and vulnerable populations; and (ii) the scope of effectiveness should be expanded to include a consideration of the various social factors that maximize (and minimize) a vaccine's effectiveness at the population level, paying particular attention to how immunization programmes impact related health gradients. We use the case of the human papillomavirus vaccine in Canada to elucidate how expanding post-market effectiveness monitoring is necessary to close the gap between clinical practice and public health, and to ensure that vaccines are effective in a morally relevant sense.

Higher Prevalence of Human Papillomavirus-Related Cervical Precancerous Abnormalities in HIV-Infected Compared to HIV-Uninfected Women

INTRODUCTION

Persistent high risk human papillomavirus (hrHPV) has been associated with cervical abnormalities and cancer. There are few studies comparing HIV-infected with uninfected African American women from the Southern U.S. We evaluated medical records of a women's cohort in an urban clinic in Tennessee to assess the prevalence of hrHPV and cytology correlates, as well as HPV vaccination rates.

METHODS

We reviewed medical records of 50 HIV infected and 304 HIV uninfected women, including Pap smears and hrHPV.

RESULTS

HIV-infected women were older than HIV-uninfected women (p<0.0001) and were more likely to have hrHPV (p=<0.0001) and LGSIL/HGSIL (p=0.006). Within the HIV uninfected group, Hispanic women were younger than non-Hispanic African American women (p=0.04) and non-Hispanic white women (p=0.0002). Non-Hispanic African-American women were younger (p=0.004) than non-Hispanic white women. Both HIV-uninfected and HIV-infected women had an 11-fold and 5-fold odds, respectively, of having precancerous lesions when harboring hrHPV, compared to hrHPV-uninfected women. Of the 125 HIV-uninfected women, only 17% had received at least one dose of the HPV vaccine. None of the 21 vaccine recipients had evidence of SILs compared to 9% of vaccine non-recipients (p=0.35, Fisher's exact test).

CONCLUSION

HIV-infected women remained at significantly higher risk for developing cervical precancerous lesions when exposed to hrHPV than their uninfected counterparts. Hispanic women were least likely to have been vaccinated. Missed HPV vaccination trended towards being associated with a higher odds of precancerous lesions. Routine HPV vaccination should be reinforced for adolescents and young women using public hospital facilities of all races and ethnic backgrounds.

Factors associated with delayed diagnosis of cervical cancer in Iran--a survey in Isfahan City

BACKGROUND

In the absence of routine screening program for cervical cancer in Iran and high rate of diagnosed cancer in its advanced stage, recognition of sociodemographic factors related to delayed diagnosis of cancer in Iran could be helpful in reducing the burden of disease in our community. The aim of this study was to determine the stage of cervical cancer at diagnosis and factors related to delayed diagnosis of cervical cancer in Isfahan, Iran.

MATERIALS AND METHODS

In this cross sectional study women diagnosed with cervical cancer for the first time by histo-pathological examination were enrolled. According to the clinical and paraclinical findings and staging of the cancer, they were classified into early and delayed diagnosis of cervical cancer. Sociodemographic factors were compared in the two groups.

RESULTS

In this study of 55 women mean age was 48.3±12.0. According to our classification 6/55 (10.9%) and 49/55 (89.1%) of them had early and delayed diagnosis of cervical cancer. Delayed diagnosis of the cancer was significantly higher in patients with lower degree of education, lower socioeconomic status, having smoker and addict husband and those who did not have a history of Pap smear test (p<0.05).

CONCLUSIONS

The results of this study indicated risk factors related to delayed diagnosis of cervical cancer. The affected women should be targeted for implementation of specialized educational programmes for improving knowledge and screening test.

[Primary cervical cancer screening]

Cervico-uterine cancer screening with cytology decrease incidence by more than 50%. The cause of this cancer is the human papilloma virus high risk, and requires a sensitive test to provide sufficient sensitivity and specificity for early detection and greater interval period when the results are negative. The test of the human papilloma virus high risk, is effective and safe because of its excellent sensitivity, negative predictive value and optimal reproducibility, especially when combined with liquid-based cytology or biomarkers with viral load, with higher sensitivity and specificity, by reducing false positives for the detection of cervical intraepithelial neoplasia grade 2 or greater injury, with excellent clinical benefits to cervical cancer screening and related infection of human papilloma virus diseases, is currently the best test for early detection infection of human papillomavirus and the risk of carcinogenesis.

Nativity and neighborhood characteristics and cervical cancer stage at diagnosis and survival outcomes among Hispanic women in California

OBJECTIVES

We examined stage of diagnosis and survival after cervical cancer among Hispanic women, and their associations with Hispanic nativity, and explored whether neighborhood socioeconomic status (SES) and residence in a Hispanic enclave modify the association of nativity with stage and survival.

METHODS

We used California Cancer Registry data (1994-2009) to identify 7958 Hispanic women aged 21 years and older with invasive cervical cancer. We used logistic and Cox proportional hazards models to estimate the associations between stage and mortality with nativity, neighborhood factors, and other covariates.

RESULTS

Foreign-born women had similar adjusted relative odds of being diagnosed with stages II through IV (vs stage I) cervical cancer compared with US-born Hispanic women. However, among foreign-born women, those in low-SES-low-enclave neighborhoods were more likely to have late-stage disease than those in high-SES-low-enclave neighborhoods (adjusted odds ratio=1.91; 95% confidence interval=1.18, 3.07). Foreign-born women had lower cervical cancer mortality (adjusted hazard ratio=0.67; 95% confidence interval=0.58, 0.76) than US-born women, but only in high enclaves.

CONCLUSIONS

Among Hispanic women, nativity, neighborhood enclaves, and SES interact in their influence on stage and survival of cervical cancer.

Sociodemographic predictors of delayed- versus early-stage cervical cancer in California

PURPOSE

We sought to evaluate and distinguish roles of sociodemographic predictors for delayed- versus early-stage cervical cancer.

METHODS

Demographic variables for 13,624 cervical cancers having complete data for age at diagnosis (4 categories), race and ethnicity (4 categories), socioeconomic status (SES) quintiles, and marital status (3 categories) were extracted from the California Cancer Registry database for the period 1996 to 2005 and analyzed using multiple logistic regression as predictors of delayed- versus early-stage diagnosis.

RESULTS

Fifty-eight percent of cervical cancers were among women younger than 50 years, compared with 46% of delayed-stage cases. Independent odds of delayed- versus early-stage cervical cancer were higher for older age categories within each race and ethnic group. Declining odds of delayed- versus early-stage diagnosis were evident for increasing SES quintiles among Asian or other (trend P = .015), non-Hispanic black (P = .024), Hispanic (P = .001), and non-Hispanic white (P = .001) women. Odds of delayed- versus early-stage cervical cancer were highest among unmarried compared with married women.

CONCLUSIONS

Our findings support evidence that older age, low SES, and unmarried status predict delayed-stage cervical cancer diagnosis in each of the four major race and ethic groups. The two lowest SES quintiles independently identified larger percentages of delayed-stage cervical cancers in each of the race and ethnicity groups assessed, particularly among Hispanic and non-Hispanic black women.

Neighborhood factors associated with time to resolution following an abnormal breast or cervical cancer screening test

BACKGROUND

The effect of neighborhood and healthcare access factors on cancer outcomes among patients enrolled in navigator programs is not clearly understood. This study assessed associations between: (i) neighborhood factors and diagnostic time to resolution (TTR) and (ii) geographic access and TTR following an abnormal breast or cervical cancer screening test among women participating in the Ohio Patient Navigator Research Program (OPNRP).

METHODS

Patient (demographic, socioeconomic status, home-to-clinic distance) and neighborhood (deprivation, racial segregation) characteristics of 801 women living in one of 285 census tracts (CT) in greater Columbus, Ohio were examined. Randomization to receive navigation occurred at the clinic level. Multilevel Cox regression and spatial analysis were used to estimate effects of various factors on TTR and assess model assumptions, respectively.

RESULTS

TTR increased as neighborhood deprivation increased. After adjustment for age, friend social support, education, and healthcare status, the TTR among women living in a neighborhood with a moderate median household income (between $36,147 and $53,099) was shorter compared with women living in low median household income neighborhoods (<$36,147; P < 0.05). There is little evidence that unmeasured confounders are geographically patterned.

CONCLUSIONS

Increased neighborhood socioeconomic deprivation was associated with longer TTR following an abnormal breast or cervical cancer screening test.

IMPACT

These results highlight the need for addressing patient- and neighborhood-level factors to reduce cancer disparities among underserved populations.

Race, ethnicity, and income factors impacting human papillomavirus vaccination rates

BACKGROUND

Human papillomavirus (HPV) infection and cervical cancer disproportionately affect low-income and minority women. HPV vaccines have the potential to either reduce or exacerbate racial disparities in HPV-related diseases and cervical cancers, depending on the equitability of vaccine uptake.

OBJECTIVES

This review aims to identify barriers and facilitators of equitable uptake of HPV vaccination among low-income and minority girls. This review discusses factors related to race, ethnicity, and income that are associated with initiation and completion rates of the 3-dose HPV vaccine series and presents targets for intervention.

METHODS

We reviewed relevant English-language literature to identify current vaccination rates and factors associated with vaccine uptake. Study findings related to race (black, Latino, Asian), and incomes were summarized.

RESULTS

Current trends in the United States indicate low uptake among all adolescents, and that rates stagnated between 2011 and 2012. Low-income and minority adolescents are equally or more likely to start the HPV vaccination series than are white and higher-income adolescents, but are less likely to complete all 3 shots. Provider recommendation is a key factor in HPV vaccination, and minorities are less likely to report receiving recommendations for HPV vaccination.

CONCLUSIONS

As black, Hispanic, and Asian populations continue to grow in the United States over the next several decades, it is imperative that we not only improve HPV vaccination rates overall, but also focus on high-risk populations to prevent an increase in cervical cancer disparities.

Exploring the role of neighborhood socio-demographic factors on HPV vaccine initiation among low-income, ethnic minority girls

Little is known about whether neighborhood factors are associated with human papillomavirus (HPV) vaccine uptake, especially among disadvantaged groups that can benefit most from the vaccine. We used data collected from immigrant, low-income mothers of adolescent girls and data from the 2005-2009 American Community Survey to investigate the relationship between HPV vaccine initiation and neighborhood characteristics. We compared initiation rates across levels of neighborhood disadvantage and employed multilevel logistic regression models to examine contextual effects on uptake. Overall, 27 % of girls (n = 479) initiated the vaccine. Initiation rates were highest among girls from the most disadvantaged neighborhoods (30 %), however, neighborhood factors were not independently associated with vaccine initiation after adjusting for individual factors. Mother's awareness of HPV, age, and insurance status were strong predictors for initiation. Future interventions should focus on improving awareness among low-income mothers as well as targeting vulnerable families outside the catchment area of public programs.

The association between neighborhood socioeconomic status and clinical outcomes among patients 1 year after hospitalization for cardiovascular disease

Residing in lower socioeconomic status (SES) neighborhoods is associated with increased risk of morbidity and mortality. Few studies have examined this association for cardiovascular disease (CVD) outcomes in a treated population in New York City (NYC). The purpose of this study was to determine the relationship between neighborhood level poverty and 1-year clinical outcomes (rehospitalization and/or death) among hospitalized patients with CVD. Data on rehospitalization and/or death at 1-year were collected from consecutive patients admitted at a university medical center in NYC from November 2009 to September 2010. NYC residents totaled 2,198. U.S. Census 2000 zip code data was used to quantify neighborhood SES into quintiles of poverty (Q1 = lowest poverty to Q5 = highest poverty). Univariate analyses were used to determine associations between neighborhood poverty and baseline characteristics and comorbidities. A logistic regression analysis was used to calculate odds ratios for the association between quintiles of poverty and rehospitalization/death at 1 year. Fifty-five percent of participants experienced adverse outcomes. Participants in Q5 (9 %) were more likely to be female [odds ratio (OR) = 0.49, 95 % confidence interval (CI) 0.33-0.73], younger (OR = 0.50, 95 % CI 0.34-0.74), of minority race/ethnicity (OR = 18.24, 95 % CI 11.12-29.23), and have no health insurance (OR = 4.79, 95 % CI 2.92-7.50). Living in Q5 was significantly associated with increased comorbidities, including diabetes mellitus and hypertension, but was not a significant predictor of rehospitalization/death at 1 year. Among patients hospitalized with CVD, higher poverty neighborhood residence was significantly associated with a greater prevalence of comorbidities, but not of rehospitalization and/or death. Affordable, accessible resources targeted at reducing the risk of developing CVD and these comorbidities should be available in these communities.

An ecological analysis of the incidence of invasive squamous cell carcinoma of the cervix in Hispanic women in the United States

PURPOSE

To evaluate the relationship between county-level characteristics and the incidence of invasive squamous cell carcinoma of the cervix among Hispanic women.

METHODS

The Surveillance, Epidemiology and End Results (SEER) Program's 18 registries from 2000-2009 were queried. Average annual age-adjusted incidence rates for invasive squamous cell carcinoma of the cervix among Hispanic women were calculated. Patients were then stratified by residence in a county with high vs low percent language isolation (LI), income, and education levels.

RESULTS

Among Hispanic women living in high LI, the highest incidence of cervical cancer was found among women residing in counties with low incomes and low education levels (11.3; CI: 10.8-11.8).

CONCLUSIONS

County-level characteristics are associated with cervical cancer incidence in Hispanic women. A more precise understanding of contributing socioeconomic factors such as language may facilitate the design of targeted research studies and interventions, and community-level public policy interventions might be effective in reducing the unequal burden of cervical cancer in Hispanic women in the United States.

Application of the Carolina Framework for Cervical Cancer Prevention

OBJECTIVE

The Carolina Framework for Cervical Cancer Prevention describes 4 main causes of cervical cancer incidence: human papillomavirus (HPV) infection, lack of screening, screening errors, and not receiving follow-up care. We present 2 applications of the Carolina Framework in which we identify high-need counties in North Carolina and generate recommendations for improving prevention efforts.

METHODS

We created a cervical cancer prevention need index (CCPNI) that ranked counties on cervical cancer mortality, HPV vaccine initiation and completion, Pap smear screening, and provision of Pap tests to rarely- or never-screened women. In addition, we conducted in-depth interviews with 19 key informants from programs and agencies involved in cervical cancer prevention in North Carolina.

RESULTS

North Carolina's 100 counties varied widely on individual CCPNI components, including annual cervical cancer mortality (median 2.7/100,000 women; range 0.0-8.0), adolescent girls' HPV vaccine initiation (median 42%; range 15%-62%), and Pap testing in the previous 3 years among Medicaid-insured adult women (median 59%; range 40%-83%). Counties with the greatest prevention needs formed 2 distinct clusters in the northeast and south-central regions of the state. Interviews generated 9 recommendations to improve cervical cancer prevention in North Carolina, identifying applications to specific programs and policies in the state.

CONCLUSIONS

This study found striking geographic disparities in cervical cancer prevention need in North Carolina. Future prevention efforts in the state should prioritize high-need regions as well as recommended strategies and applications in existing programs. Other states can use the Carolina Framework to increase the impact of their cervical cancer prevention efforts.

Are HPV vaccination services accessible to high-risk communities? A spatial analysis of HPV-associated cancer and Chlamydia rates and safety-net clinics

PURPOSE

While HPV vaccines can greatly benefit adolescents and young women from high-risk areas, little is known about whether safety-net immunization services are geographically accessible to communities at greatest risk for HPV-associated diseases. We explore the spatial relationship between areas with high HPV risk and proximity to safety-net clinics from an ecologic perspective.

METHODS

We used cancer registry data and Chlamydia surveillance data to identify neighborhoods within Los Angeles County with high risk for HPV-associated cancers. We examined proximity to safety-net clinics among neighborhoods with the highest risk. Proximity was measured as the shortest distance between each neighborhood center and the nearest clinic and having a clinic within 3 miles of each neighborhood center.

RESULTS

The average 5-year non-age-adjusted rates were 1,940 cases per 100,000 for Chlamydia and 60 per 100,000 for HPV-associated cancers. A large majority, 349 of 386 neighborhoods with high HPV-associated cancer rates and 532 of 537 neighborhoods with high Chlamydia rates, had a clinic within 3 miles of the neighborhood center. Clinics were more likely to be located within close proximity to high-risk neighborhoods in the inner city. High-risk neighborhoods outside of this urban core area were less likely to be near accessible clinics.

CONCLUSIONS

The majority of high-risk neighborhoods were geographically near safety-net clinics with HPV vaccination services. Due to low rates of vaccination, these findings suggest that while services are geographically accessible, additional efforts are needed to improve uptake. Programs aimed to increase awareness about the vaccine and to link underserved groups to vaccination services are warranted.

Socioeconomic position and survival after cervical cancer: influence of cancer stage, comorbidity and smoking among Danish women diagnosed between 2005 and 2010

Background:

In an attempt to decrease social disparities in cancer survival, it is important to consider the mechanisms by which socioeconomic position influences cancer prognosis. We aimed to investigate whether any associations between socioeconomic factors and survival after cervical cancer could be explained by socioeconomic differences in cancer stage, comorbidity, lifestyle factors or treatment.

Methods:

We identified 1961 cases of cervical cancer diagnosed between 2005 and 2010 in the Danish Gynaecological Cancer database, with information on prognostic factors, treatment and lifestyle. Age, vital status, comorbidity and socioeconomic data were obtained from nationwide administrative registers. Associations between socioeconomic indicators (education, income and cohabitation status) and mortality by all causes were analysed in Cox regression models with inclusion of possible mediators. Median follow-up time was 3.0 years (0.01–7.0).

Results:

All cause mortality was higher in women with shorter rather than longer education (hazard ratio (HR), 1.46; 1.20–1.77), among those with lower rather than higher income (HR, 1.32; 1.07–1.63) and among women aged<60 years without a partner rather than those who cohabited (HR, 1.60; 1.29–1.98). Socioeconomic differences in survival were partly explained by cancer stage and less by comorbidity or smoking (stage- and comorbidty- adjusted HRs being 1.07; 0.96–1.19 for education and 1.15; 0.86–1.52 for income).

Conclusion:

Socioeconomic disparities in survival after cervical cancer were partly explained by socioeconomic differences in cancer stage. The results point to the importance of further investigations into reducing diagnosis delay among disadvantaged groups.

Vulvar/vaginal melanoma: an updated surveillance epidemiology and end results database review, comparison with cutaneous melanoma and significance of racial disparities

OBJECTIVE

We aimed to compare the differences in demographic features, clinicopathologic features, and survival in patients with vulvar/vaginal melanoma versus cutaneous melanoma with a special emphasis on race.

MATERIALS AND METHODS

Data were obtained from the Surveillance Epidemiology and End Results database from 1973 to 2008. Kaplan-Meier curves and Cox multivariate model were used for statistical analysis.

RESULTS

Seven hundred sixty-two patients with vulvar/vaginal melanoma and 55,485 patients with cutaneous melanoma patients were included in the study. Twenty-eight patients of the vulvar/vaginal group and 334 patients of the cutaneous group were black (3.6% vs 0.6%, respectively). The median age at the time of diagnosis was 68 years in the vulvar/vaginal group and 52 years in the cutaneous group (P < 0.0001). Three hundred fifty patients (45.9%) in the vulvar/vaginal and 46,499 patients (83.8%) in the cutaneous group presented with localized disease (P < 0.0001), whereas 64 patients (8.4%) in the vulvar/vaginal group and 1520 patients (2.7%) in cutaneous group presented with advanced disease (P = 0.0081). The median survival of the black patients was 16 months in the vulvar/vaginal group and 124 months in the cutaneous melanoma group (P < 0.0001). The median survival in the nonblack population was 39 months in the vulvar/vaginal group compared to 319 months in the cutaneous melanoma group (P <0.0001). In multivariate analysis performed for patients between 1988 and 2008, age, stage, and positive lymph nodes were negative independent prognostic factors for survival in vulvar/vaginal melanoma; whereas age, race, stage, radiation therapy, and lymph node positivity were negative prognostic factors in cutaneous melanoma.

CONCLUSION

These findings emphasize that cutaneous and vulvar/vaginal melanomas have different clinicopathologic features and survival patterns.
