Impact of Patient Navigation
  • Reduction treatment interruptions?
  • Overall experience during treatment enhanced?
  • Any change in trust towards the health care
    system?
  • Cultural competency

Surveys
  • 1. Community Survey to identify and document the
    barriersto timely and effective cancer
    screening, diagnosis and treatment for the Native
    American community
  • Opened in 06/04 data collection completed
    (N984)
  • 2. Cancer Patient Survey to assess barriers to
    timely and effective cancer care in a population
    with demonstrated stage disparities and to
    evaluate patient navigationprogram
  • 204 surveys completed 80 NAs, 124 non-NA
  • Interim analysis completed (see next slides)
    accrual ongoing
  • Co-PI Ashleigh Guadagnolo, MD, MPH University
    of Texas MD Anderson Cancer Center

Cancer Survey Mistrust and Satisfaction
  • Data set N165 (52 Native Americans and 113
    non-Native)
  • Native Americans expressed significantly higher
    levels of mistrust (p0.0001) and lower levels of
    satisfaction with health care (p 0.0001)
  • In multivariable analyses, Native American race
    was the only factor found to be significantly
    predictive of higher mistrust and lower
    satisfaction with healthcare, even when adjusting
    for income, education, and geographic remoteness.

disparities in trust and satisfaction with health
care among Native Americans presenting for cancer
treatment. Manuscript in review. Submitted
October, 2007.
10
Cancer Survey Knowledge and Attitudes
  • Native Americans scored lower on screening
    knowledge battery (p0.0001) and exhibited more
    negative attitudes about cancer treatment than
    non-NAs (p 0.0001)
  • In multivariable analyses, Native American
    race was the only factor found to be
    significantly predictive lower screening
    knowledge and more negative attitudes about
    cancer treatment, even when adjusting for income,
    education, and geographic remoteness.

disparities in knowledge, attitudes, and stage
for screen-detectable cancers among Native
Americans presenting for cancer treatment.

11
Cancer Survey Persistent Stage Disparity
  • Native Americans presented with more
    advanced-stage screen detectable cancers than
    non-NAs (breast, cervix, colorectal, prostate)
    45 vs. 24, p0.04.
  • Of patients with screen-detectable cancer, the
    identifying diagnostic was a screening test for
    68 of white vs. 37 of Native American patients.
    (p0.006).

12
Cancer Survey Implications
  • Stage disparity shows continued barriers to
    timely and effective cancer care
  • Mistrust and less satisfaction with prior health
    care emphasizes need for patient navigation
  • Less screening knowledge and more negative
    attitudes toward cancer care emphasizes need for
    educational interventions

13
Community Survey Screening Rates (N900)
  • Breast 61 (214/353)
  • Cervix 49 (275/567)
  • Prostate 32 (32/100)
  • Colorectal
  • females 24 (41/172)
  • males14 (13/91)

14
Community Survey Updated Results (N900)
  • AIs indicated that they were more likely to be
    screened if
  • a screening advocate made public presentation
  • a screening clinic came to their community
  • they knew more about screening
  • they had help with transportation
  • they had help making appointments
  • Fifty-three percent of males and 70 of females
    planned on obtaining cancer screening

15
Phase II Trial HDR Brachytherapy Stage I and II
Breast Cancer Rapid City PI Petereit
  • Similar criteria as previous APBI RTOG trial
  • 34 Gy/10 Fxs
  • Endpoints
  • Evaluate the rate of acute, late toxicities
  • Efficacy, local control, cosmesis
  • 20 pts (4 AIs) enrolled on clinical trial out of
    about 100 total procedures
  • 10 pts interstitial technique, 10 pts Mammosite
  • 2 G3 toxicity recurrent infection requiring
    drainage
  • both are with Mammosite technique

16
Phase II Study High Dose Rate Brachytherapy
Advanced Prostate Cancer
  • Patient eligibility intermediate, high-risk
    prostate cancer
  • Androgen ablation 6 to 12 months
  • EBRT 2.2 Gy X 16 over 15 treatment days, HDR 9 Gy
    X 2
  • Endpoints
  • Evaluate the rate acute, late toxicities
  • Efficacy HDR boost
  • 4 pts (0 AIs) enrolled on clinical trial out of
    about 100 total procedures
  • No G3 toxicities
  • Low accrual because of tomotherapy / IMRT trial
  • HDR FX schedule recently changed from 6.5 x 3, to
    9 Gy x 2 to increase accrual by eliminating need
    for hospitalization
  • new changes allow IMRT and PSI

ATM mutations in Native Americans Possible
Association with Cancer and Radiotherapy
Toxicities
  • PIs Moser, A. Petereit, D.
  • To determine the association between ATM
    heterozygosity and sensitivity to radiation
  • Gene sequencing underwayAmy Moser, PhD, UW
  • Rapid City enrollment
  • 36 American Indians
  • 51 non-Natives

22
ATM Preliminary Results
  • DNA was isolated from 53 NA and non-NA undergoing
    radiation therapy for various cancers
  • 26 of 28 AIs agreed to participate
  • Variants were identified in 14 of 61 sequenced
    exons -11 variants would result in an AA change,
    functional change protein- 3 variants would not
    change AA - 3 variants may be new compared to
    current database

Predictors of Radiosensitivity through Genomics
  • Using gene array technology, gene expression
    changes in lymphocytes after radiation exposure
    will be characterized as a surrogate to determine
    whether the expression pattern differs between AI
    patients who experienced adverse reactions, as
    compared with those who did not
  • 20 AI cancer patients 10 with and 10 without
    radiation sides effects
  • Goal identify markers that might be used to
    identify AI patients who are likely to suffer
    adverse reactions due to radiotherapy, and to
    begin to understand the genetic basis of adverse
    reactions
  • Funding source University of Wisconsin

33
Walking Forward Navigator-Driven Community
Education and Screening
  • Goal Expand and enhance a Navigator-driven
    cancer education and screening program with
    American Indians (AIs) in the Northern Plains
  • Aim Increase AI screening for breast, cervix,
    colorectal, and prostate cancers by 20
  • The goal of this 12-month supplement is to expand
    and enhance a Navigator-driven cancer education
    and screening program with AIs in the Northern
    Plains
  • Project builds upon the ongoing Walking Forward
    Study to expand the Community Research
    Representatives (CCR) roles to become cancer
    screening coordinators

Funding source NCI
34
Walking Forward Navigator-Driven Community
Education and Screening
  • Partners Native American Cancer Research
    (NACR), Aberdeen Area Tribal Chairmens Health
    Board, University of Wisconsin Cancer Information
    Service and Cancer Division, and Spirit of Eagles
    Program
  • CCRs trained to coordinate, implement and
    evaluate community cancer workshops to increase
    knowledge and recruitment to appropriate breast,
    cervix, colon, and prostate cancer screenings
  • Community workshops will be based on NACRs
    validated, intertribal "Get on the Path to
    Health" curricula (i.e., specific six-part
    curricula on (a) breast, (b) cervix, (c) colon,
    and (d) prostate

35
Next Grant Rapid City and UW
  • Need to expand Patient Navigation
  • UW School of Public Health
  • Need to Promote Cancer Screening Education
  • UW School of Public Health
  • Desperately need to implement Hospice
  • James Clearly, MD
  • Lessons learned in Western, SD, could easily be
    applied to other disparate and rural populations
    - Wisconsin, elsewhere
