Outline
• American Indian and Alaska Native sovereignty and health care delivery
• Cervical cancer burden in American Indian and Alaska Natives
• Promising interventions for Cervical Cancer Prevention– HPV vaccine– Cervical Cancer Screening
The Federal - Tribal Relationship
Is unique and is expressed through:
– Recognition of Tribal sovereignty
– Government to government interactions
– Support of the Federal trust responsibility
– Tribal consultation
Background: Health care for AI/AN• AI/AN have sovereignty and self-governance• Indian Health Service (IHS) provides health services to
AI/AN– comprehensive health service delivery system for
approximately 1.9 million AI/AN who belong to 560+ federally recognized tribes in 35 states
• Members of these tribes are eligible to receive, without charge, primary healthcare from IHS
• Self governance contracts with tribal governments in some settings
• Private/public clinics outside IHS also used depending on employment, Veterans benefits, Medicaid, Medicare
Burden of HPV-AssociatedDiseases/Cancers
• Genital warts• Recurrent respiratory
papillomatosis
• Cervical cancers• Vaginal/Vulvar cancers• Anal cancers• Penile cancers• Oropharyngeal and
Oral Cavity cancers
> 90% HPV 6, 11
~30-80% HPV 16, 18
BackgroundBurden of HPV-associated Cervical
Cancers, AI/AN
• Considerable misclassification of race/ethnicity• Regional variations in cervical cancers
– Highest age-adjusted rates reported in Southern Plains (14.1 per 100,000) and Northern Plains (12.5 per 100,000)
• Overall higher rates of cervical cancer than non Hispanic White women (9.4 per 100,000), and more likely to be diagnosed at later stage of disease
Becker TM, Cancer 2008
Interventions to reduce HPV-associated cancers
• HPV Vaccine implementation– Implementation status as of beginning of 2010– School based vaccine implementation project– Evaluation of HPV Vaccine Impact
• Cervical cancer screening – Northern Plains evaluation of cervical self-sampler

Fort Berthold HPV Vaccine Implementation Project
• Fort Berthold Reservation: Affiliated Tribes Mandan, Hidatsa, and Arikara
• 5 School Districts in Tribal Areas participated– Meetings with parents/schools, education
materials– Permission slips collected from parents before the
beginning of the school year – Snacks, incentives provided—combined with a
nutrition/exercise program• 138 girls completed series, 453 doses distributed• Intention is to expand this program next school
year
Arctic Investigations Program, CDCAnchorage, AK
• Collaboration with Alaska Native Tribal Health Consortium and Southcentral Foundation, CDC is conducting projects to measure HPV vaccine impact in Alaska Natives– HPV genotypes in women at time of coloposcopy– Immunogenicity and duration of immunity among
teens receiving HPV vaccine– HPV genotypes in archived cervical cancer
– Development of AN specific education materials based on focus groups
HPV types Causing Cervical Cancers in Alaska Native Women
• P-810
“Prevalence of HPV types in archived cervical cancer specimens from Alaska Native women, 1980-2007”

Northern PlainsCervical Cancer Screening Project
• Challenges in rural and underserved settings for cervical cancer screening– Time constraints, travel, childcare– In Aberdeen Area, less than 1/3 of AI women have
annual Pap screening• This project is a collaboration between Native Plains
NARCH, the Tribal Chairman’s Health Board, University South Dakota
• Goal is to evaluate if cervical self-sampler can improve experiences of cervical cancer screening in Northern Plains AI women
HPV self-sampling to improve cervical cancer screening in AI communities
Study evaluation• Women in tribal settings presenting for cervical
cancer screening recruited• Each woman will have a traditional Pap smear and
HPV testing• Teaching session on how to administer self-sampler• Woman self collects sample at home, 30 and 90 days
later • Evaluation of acceptability, validity
HPV Vaccination of Boys
• P-734• Survey of IHS providers about intentions to vaccinate
boys
