6Impact of Patient Navigation
- Reduction treatment interruptions?
- Overall experience during treatment enhanced?
- Any change in trust towards the health care
system? - Cultural competency

8Surveys
- 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
9Cancer 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.
10Cancer 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.
Guadagnolo A, Petereit D, et al. Racial
disparities in knowledge, attitudes, and stage
for screen-detectable cancers among Native
Americans presenting for cancer treatment.
Manuscript in review.
11Cancer 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).
12Cancer 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
13Community Survey Screening Rates (N900)
- Breast 61 (214/353)
- Cervix 49 (275/567)
- Prostate 32 (32/100)
- Colorectal
- females 24 (41/172)
- males14 (13/91)
14Community 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
15Phase 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
16Phase 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

21ATM 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
22ATM 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

26Successful Recruitment Clinical Trials
- As of June 2007, 21 AIs who underwent patient
navigation during radiation were enrolled on a
clinical trial - Reasons for non-participation in clinical
treatment trials for AIs - advanced stage and/or poor performance status
(29) - no trial available for cancer site (16)
- and other reasons for ineligibility after
evaluation (15) - only one patient refused participation in a
clinical trial after being deemed potentially
eligible
27Clinical Trials Operating Committee (CTOC)

the recruitment of minority populations in
clinical cancer trials -NCI Clinical Trials

32Predictors 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
33Walking 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
34Walking 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
