©2013 MFMER | slide-5 Overview of the Mayo Clinic Historical Points of Interest Present Day
©2013 MFMER | slide-6 Founding of the Mayo Clinic
©2013 MFMER | slide-7 Mayo - History 1864: Dr. William Worrall Mayo moves to Rochester to examine new recruits for the Union Army 1883, 1888: Dr. Mayos two sons, William J. and Charles H., join him in practice after finishing medical school
©2013 MFMER | slide-8 Founding of the Mayo Clinic December,1876 Mother Alfred commissioned to establish an academy in Waseca, MN. In 1877 she also established a mission house and day school in Rochester, Minnesota 1883: Tornado strikes Rochester. Mother Alfred Moes, of the Sisters of Saint Francis, proposes to build and staff a hospital if Dr. William Worrall Mayo and his sons will provide medical care. Saint Marys Hospital opens in 1889 with 27 beds
©2013 MFMER | slide-9 Mayo - History 1892: More physicians are invited to join, thus beginning the concept of an integrated group practice. The team approach naturally leads to a division of labor, specialists in different fields working together 1905: Louis Wilson, M.D., develops a rapid way to diagnose surgical specimens (quick-frozen tissue stained with methylene blue), which allows Mayo surgeons to explore, diagnose and repair, all in one operation
©2013 MFMER | slide-10 Mayo - History 1914: Mayo isolates thyroxin, the principal active component of the thyroid gland 1920: Mayo develops a system for grading cancer on a numerical basis that is adopted worldwide and still used today 1934: Edward Kendall, Ph.D., isolates cortisone, a hormone from the suprarenal cortex that will later be used to treat rheumatoid arthritis with dramatic results 1950: Edward Kendall, Ph.D., and Philip Hench, M.D., are awarded the Nobel Prize for the isolation and first clinical use of cortisone
©2013 MFMER | slide-11 Mayo - History 1919: The Mayos turn over the assets of Mayo Clinic to the nonprofit Mayo Properties Association, the forerunner of Mayo Foundation 1915: Doctors come from all over the world to observe and learn, leading to the organization of one of the worlds first formal graduate training programs for physicians, the Mayo School of Graduate Medical Education
©2013 MFMER | slide-12 Mayo - History Early 1900s rapid growth of infrastructure
©2013 MFMER | slide-13 Mayo - History 1939: Will and Charlie Mayo pass away within 2 months of each other

©2013 MFMER | slide-28 Mayo Clinic Activities in Alaska Adult and Pediatric Cardiac Clinics, 1963 - 1980 Teams of Mayo Cardiac physicians traveled to Alaska on an annual basis to conduct pediatric and adult cardiac clinics, including assessment of surgical candidates for referral to the Mayo Clinic The cardiac and surgery clinics were first coordinated by the Alaska Territorial Office and then the State of Alaska, with the assistance of handicapped and crippled children programs The clinics continued until Alaska medical facilities were able to provide the needed surgical services in- state

©2013 MFMER | slide-37 Cancer Death Rates by Gender Cancer remains the leading cause of death among Alaska Native people. The all cancer mortality rate has exceeded the US white cancer mortality rate for more than 30 years. There have not been any significant declines. The leading cause of cancer death is lung cancer; where the mortality rate is 40% higher in Alaska Native people than US whites (Cancer in Alaska Native People 1969-2008. 40-Year Report. http://anthctoday.org/epicenter/)

©2013 MFMER | slide-44 Colorectal Cancer Incidence in AI/AN People
©2013 MFMER | slide-45 Colon Cancer – Risk Factors Defined Risk Factors Diet: Consumption of animal fat, meat, and protein and a concomitant decreased consumption of fiber Tobacco: 1.4-fold increase risk of death from colorectal cancer in smokers compared to non- smokers (Int J Cancer 124:2406-15, 2009) Hereditary Factors: Accounts for approximately 15% of colorectal cancer across populations
©2013 MFMER | slide-46 Colon Cancer – Molecular Changes (Gastroenterology 143:1442-60, 2012)
©2013 MFMER | slide-47 Assessing Molecular Changes in Alaska Native People with Colorectal Cancer CRC from 329 Alaska Native people (165 Eskimo, 111 Indians, and 53 Aleut) evaluated for defective DNA mismatch repair (MMR), testing tumors for altered protein expression (hMLH1, hMSH2, and hMSH6) and for the presence of microsatellite instability (MSI) Findings 46 (14%) showed both MSI and altered protein expression; 42 (91%) with a loss of hMLH1, 3 (7%) hMSH2, and 1 (2%) hMLH1/hMSH6. (Cancer Epidemiol Biomarkers Prev 2007;16(11):2344–50)
©2013 MFMER | slide-48 Assessing Molecular Changes in Alaska Native People with Colorectal Cancer Findings Continued Tumors with loss of hMLH1 further evaluated for hMLH1 promoter hypermethylation and for the BRAF-V600E mutation (23 of 27) tested positive for the V600E alteration Conclusion CRC with defective MMR among the Eskimo sample fit the typical profile for hMLH1-related cancer associated with sporadic CRC, whereas the pattern in the Aleut and Indian suggests the possibility that germ line hMLH1 mutations may be present

©2013 MFMER | slide-52
©2013 MFMER | slide-53 Based on tumor exfoliation Whole colonocytes Proteins Metabolites RNA DNA Nearly 100% discrimination of CRC and adenomas from normal mucosa Highly sensitive assay technique, QuARTS (quantitative allele-specific real-time target and signal amplification)
©2013 MFMER | slide-54 Stool DNA Identified 85% of patients with CRC and 54% of patients with adenomas 1 cm with 90% specificity (aggregate 87% detection rate for CRC stages IIII). Detection rates increased with adenoma size: 54% 1 cm, 63% >1 cm, 77% >2 cm, 86% >3 cm, and 92% >4 cm (P <.0001). Based on receiver operating characteristic analysis, the rate of CRC detection was slightly greater for the training than the test set (P =.04), whereas the rate of adenoma detection was comparable between sets. Sensitivities for detection of CRC and adenoma did not differ with lesion site (Gastroenterology. 2012 Feb; 142(2): 248-56) Training Set Test Set

©2013 MFMER | slide-57 Rates of tobacco use are higher in AN people. Recent Behavioral Risk Factor Surveillance System (BRFSS) survey the rate of smoking in AN people is 45% compared to 21% in non-Native Alaskans
©2013 MFMER | slide-58 Yukon-Kuskokwim Neonatal Tobacco Exposure Pilot project, 1998 Mayo Nicotine Dependence Center Director Richard Hurt, MD and staff and YKHC program director Caroline Renner, MPH, collaborated on a pilot study to assess the impact of exposure of newborn infants to spit tobacco used by mothers during pregnancy and delivery.

©2013 MFMER | slide-63 Breast Cancer Risk Factors Risk factors: Age: menarche, first birth, menopause Parity Family history of breast cancer Hormone replacement therapy Lactation Hysterectomy Prior breast biopsy Smoking status Ethnic group Breast Density
©2013 MFMER | slide-64 Mammogram density has also not been studied in Alaska Native women The breast tissue parenchymal pattern as depicted on a mammogram is a factor that is influenced by hormonal breast cancer risk factors such as age at first birth, parity, menopause, and HRT3 Density is a strong independent indicator of breast cancer risk
©2013 MFMER | slide-65 Retrospective review of a sample of all sequential screening mammography examinations that were performed at the Alaska Native Medical Center between January and August of 1998 (n: 662 women) Aleut and Indian women were less likely to have high-density mammograms than were Eskimo women (P 0.0448). No significant differences were found between ethnic group for conventional breast cancer risk factors

(Cancer Information Resource Center for Learning and Education): serves as a national resource for information and educational materials specifically targeting the American Indian/Alaska Native (AI/AN) population.
