Cervical Cancer Prevention: New Tools and Old Barriers

Cervical cancer is the second most common female tumor worldwide, and its incidence is disproportionately high (>80%) in the developing world. In the United States, in which Papanicolaou (Pap) tests have reduced the annual incidence to approximately 11,000 cervical cancers, >60% of cases are reported to occur in medically underserved populations as part of a complex of diseases linked to poverty, race/ethnicity, and/or health disparities. Because carcinogenic human papillomavirus (HPV) infections cause virtually all cervical cancer, 2 new approaches for cervical cancer prevention have emerged: 1) HPV vaccination to prevent infections in younger women (aged ≤18 years) and 2) carcinogenic HPV detection in older women (aged ≥30 years). Together, HPV vaccination and testing, if used in an age‐appropriate manner, have the potential to transform cervical cancer prevention, particularly among underserved populations. Nevertheless, significant barriers of access, acceptability, and adoption to any cervical cancer prevention strategy remain. Without understanding and addressing these obstacles, these promising new tools for cervical cancer prevention may be futile. In the current study, the delivery of cervical cancer prevention strategies to these US populations that experience a high cervical cancer burden (African‐American women in South Carolina, Alabama, and Mississippi; Haitian immigrant women in Miami; Hispanic women in the US‐Mexico Border; Sioux/Native American women in the Northern Plains; white women in the Appalachia; and Vietnamese‐American women in Pennsylvania and New Jersey) is reviewed. The goal was to inform future research and outreach efforts to reduce the burden of cervical cancer in underserved populations. Cancer 2010.

Assessing the acceptability of self-sampling for HPV among Haitian immigrant women: CBPR in action

ObjectiveTo determine whether pairing self-sampling for HPV with community health workers (CHWs) is a culturally acceptable method for cervical cancer screening among Haitian immigrant women residing in Little Haiti, the predominately Haitian neighborhood in Miami, FL.MethodsAs part of a larger, ongoing community-based participatory research (CBPR) initiative in Little Haiti, Haitian CHWs recruited 246 eligible women to this study. Participants provided self-collected cervical specimens for HPV testing and answered a series of questions about their experience with self-sampling for HPV.ResultsThe vast majority of women (97.6%) was comfortable using the self-sampler at home, would recommend this screening method to their friends and/or family members (98.4%), and described the sampler as easy to use (95.1%). Additionally, 97% of all self-collected specimens were deemed adequate for HPV testing.ConclusionsWhen paired with CHWs, who are of Haitian descent and well respected in Little Haiti, self-sampling is a highly acceptable method of cervical screening for Haitian women in this ethnic enclave. This approach addresses critical access barriers, including poverty, language difficulties, and sociocultural concerns about modesty, that may similarly affect Pap smear utilization among other immigrant or medically underserved population sub-groups. Coupled with generally positive reviews of the device, the low rate of insufficient specimens for testing suggests that this device is promising for use in non-clinical settings.

Women with HIV are more commonly infected with non-16 and -18 high-risk HPV types.

OBJECTIVE To review and summarize evidence from clinical, translational and epidemiologic studies which have examined the clinically relevant aspects of HPV type prevalence and cervical dysplasia in HIV-infected women. METHODS Relevant studies were identified through a MEDLINE search. References of identified reports were also used to identify additional published articles for review. RESULTS HIV-infected women in different geographic regions (such as Zambia, Brazil, Rochester NY) appear to be infected with less prevalent types of HR-HPV as compared to the general population who, across all continents, are more commonly infected with types 16 and 18. Secondly, integration of HPV DNA into the host genome is no longer thought to be a necessary cause of malignant transformation of cervical cells. However, rate of integration appears to differ by the type of HPV. In fact, the types of HPV which appear to be more common in cervical dysplasia of HIV-infected women are the same types which are more likely to require integration for malignant transformation. Finally, HPV types found in HIV-infected women are relatively common and likely to persist. The most common among these types belong to the alpha-9 and -7 species which are the most carcinogenic species. CONCLUSION Given that current vaccines target HR-HPV-16/18, the findings from the above mentioned studies may have important implications for the design of HPV vaccines that target the types of HPV associated with disease risk in HIV-infected women. HPV typing and assessment of the physical state (whether it is integrated or episomal) appear to be two valuable parameters for the prognostic evaluation of dysplastic lesions of the uterine cervix. This, however, has not yet been assessed in HIV-infected women. Recent data about the immune response in HPV/HIV co-infection may lead to understanding potential mechanisms for less virulent HPV causing malignant transformation in HIV-infected women.

Knowledge of HPV among United States Hispanic women: opportunities and challenges for cancer prevention.

In the United States, Hispanic women contribute disproportionately to cervical cancer incidence and mortality. This disparity, which primarily reflects lack of access to, and underutilization of, routine Pap smear screening may improve with increased availability of vaccines to prevent Human Papillomavirus (HPV) infection, the principal cause of cervical cancer. However, limited research has explored known determinants of HPV vaccine acceptability among Hispanic women. The current study examines two such determinants, HPV awareness and knowledge, using data from the 2007 Health Interview National Trends Survey (HINTS) and a cross-section of callers to the National Cancer Institutes (NCI) Cancer Information Service (CIS). Study data indicate that HPV awareness was high in both samples (69.5% and 63.8% had heard of the virus) but that knowledge of the virus and its association with cervical cancer varied between the two groups of women. The CIS sample, which was more impoverished and less acculturated than their HINTS counterparts, were less able to correctly identify that HPV causes cervical cancer (67.1% vs. 78.7%) and that it is a prevalent sexually transmitted infection (STI; 66.8% vs. 70.4%). Such findings imply that future research may benefit from disaggregating data collected with Hispanics to reflect important heterogeneity in this population subgroups ancestries, levels of income, educational attainment, and acculturation. Failing to do so may preclude opportunity to understand, as well as to attenuate, cancer disparity.

Patnè en Aksyon: Addressing Cancer Disparities in Little Haiti Through Research and Social Action

Haitian women living in Miami, Florida, experience an increased risk of developing and dying from cervical cancer compared with women in other racial/ethnic minority and immigrant groups in the area. In response to this disparity, academic investigators from a local university-based cancer center and community leaders from Little Haiti, the predominately Haitian neighborhood in Miami, created Patnè en Aksyon (Partners in Action), a campus-community partnership. We describe the partnerships effort to document the prevalence of lifetime and routine Papanicolau test use using community-based participatory research methods. Community health workers indigenous to the area recruited participants from various community venues throughout Little Haiti and administered informal, brief interviews to assess their screening practices. The results indicate that Haitian women are underscreened and underscore the importance of community involvement in study implementation.

One Size Does Not Fit All: Differences in HPV Knowledge between Haitian and African American Women

Background: Historically, all black persons, regardless of ancestry or country of origin, have been categorized as one group for cancer research and control efforts. This practice likely masks variability in exposure to determinants of disease, as well as in risk of cancer incidence and mortality. The current study examines potential differences in knowledge of human papilloma virus (HPV) between Haitian women living in Little Haiti, Miami, Florida, and a national sample of predominately African American women. Methods: Data for Haitian women were collected in 2007 as part of an ongoing community-based participatory research initiative in Little Haiti. For purposes of comparison, we used data from a largely African American subsample of the 2007 Health Information National Trends Survey (HINTS). These data sources used identical items to assess HPV knowledge, providing a unique opportunity to examine how this outcome may vary between two very distinct populations who are often grouped together for research and disease surveillance. Results: Relative to the HINTS sample, Haitian women were far less likely to have heard about HPV. Conclusions: Study data highlight important differences in Haitian and African American womens knowledge of HPV, a known determinant of cervical cancer risk. Such findings suggest that continuing to classify persons of similar phenotype but different cultural backgrounds and lifetime exposures as one group may preclude opportunity to understand, as well as attenuate, health disparity.

Barriers to breast cancer screening among Haitian immigrant women in Little Haiti, Miami

Previous research has not examined barriers to mammography screening among Haitian immigrant women through their own discourse. Community Health Workers conducted in-depth interviews with Haitian women in Little Haiti, Miami. We used a grounded theory approach to analyze data from the in-depth interviews. Emergent themes coalesced into three core categories of screening barriers: Structural, Psychosocial, and Socio-Cultural. We developed a model of screening barriers to depict the themes within each core category. Screening barriers must be examined and understood from the social contexts in which they are produced in order to create meaningful interventions.

Community-based participatory research in Little Haiti: challenges and lessons learned.

Background: Community-based participatory research (CBPR) is an effective methodology for developing relevant interventions with socially marginalized communities. However, implementing CBPR methods is challenging for several reasons. This paper presents challenges encountered in the context of an ongoing CBPR initiative in Little Haiti in Miami, Florida, and describes the solutions used to address them.Objectives: We sought to describe the challenges faced and lessons learned while conducting CBPR in Little Haiti.Methods: Community–academic partnerships were created to guide the creation of culturally relevant cancer interventions and research.Lessons Learned: Historical distrust of research, cultural constructions of health and illness, and literacy issues are key considerations when developing partnerships with Haitian and other marginalized, immigrant communities.Conclusions: Partnerships are fostered over time through demonstrated mutual commitment to improving health and building community capacity. Communities must play an active role throughout the research process to ensure that studies are culturally relevant, and ensuing intervention, sustainable.

Does a Community-Based Stress Management Intervention Affect Psychological Adaptation Among Underserved Black Breast Cancer Survivors?

BACKGROUND In this randomized trial, Project CARE, we examined whether participation in a cognitive-behavioral stress management and breast cancer wellness and education program improved psychological outcomes among a sample of underserved black breast cancer survivors. METHODS Both complementary medicine interventions were 10-sessions, manualized, group-based, and were culturally adapted for black women in the community from evidence-based interventions. Participants were 114 black women (mean age = 51.1, 27-77 years) who had completed breast cancer treatment 0-12 months before enrollment (stages 0-IV, mean time since cancer diagnosis = 14.1 months). Women were enrolled upon completion of curative treatment (ie, surgical, chemotherapy, radiation oncology) and randomized to receive cognitive-behavioral stress management or cancer wellness and education program. RESULTS There was a remarkable 95% retention rate from baseline to 6-month follow-up. Participants in both conditions showed statistically significant improvement on indices of psychological well-being, including overall quality of life (Functional Assessment of Cancer Therapy-Breast), intrusive thoughts (Impact of Event Scale-Revised), depressive symptoms (Center for Epidemiologic Studies-Depression), and stress levels (Perceived Stress Scale) over the 6-month postintervention follow-up (all repeated measures analysis of variance within-subjects time effects: P < .05, except for overall mood; Profile of Mood States-Short Version). Contrary to hypotheses, however, condition × time effects were not statistically significant. CONCLUSIONS Findings suggest that improvements in multiple measures over time may have been due to intensive training in stress management, extensive provision of breast cancer information, or participation in an ongoing supportive group of individuals from a similar racial background. Implications bear on decisions about appropriate control groups, the timing of intervention delivery during the treatment trajectory, and perceived support from the research team.
