Strategies for reducing colorectal cancer risk
Maintain a healthy weight
Be physically active
Consume a healthy diet
Limit alcohol consumption
Consume recommended levels of calcium
Avoid tobacco products
Screening at 50, OR earlier with a family history of adenomas or CRC
Who should begin screening before 50?
High risk Age to begin
Familial adenomatous polyposis (FAP) 10-12 years
Lynch syndrome 20-25 years*
Inflammatory bowel disease(ulcerative colitis or Crohn disease)
Varies depending on age at onset
*Or 10 years before youngest case in immediate family
Who else should begin screening before 50?
Increased risk Age to begin
Cancer/adenomas in a first-degree relative
40 years OR10 years before youngest case
Cancer in > 2 second-degree relatives 40 years
Conclusions
• CRC incidence rates continue to increase in young adults
• Know when to begin screening based on your family history
• Increase awareness to hasten follow-up of symptomatic young adults
1. Rectal bleeding2. Abdominal pain3. Change in bowel habits
• Critical need for further research to elucidate the cause of this trend

What is a colon adenomatous polyp?
Polyps begin in the cells of glandular structures lining the colon. Most polyps are benign, but one kind is the cause of greater concern–the colon adenomatous polyp (adenoma). This growth is associated with DNA changes in the lining of the colon. Polyps can become cancerous if undetected or ignored.

How common is CRC in adults younger than 50?
• ~10% of CRCs arise in men and women <50 yrs
140,000 new cases, 2014
• Incidence in US is 7 per 100,000 people/year (<50) vs 130 per 100,000 people/year (≥50)
14,000
10% <50 years
How common are inherited CRC syndromes in EAO-CRC?
• ~10% of EAO-CRC is attributed to known inherited CRC syndromes– 14,000 ~1,400 total cases
• Likely underestimated– This has not been comprehensively studied
• What about the pool of “at-risk” individuals?
10%
Lynch Syndrome
Most prevalent hereditary CRC syndrome 5% of all CRC
Defective DNA Mismatch Repair Mutations in MLH1, MSH2, MSH6, PMS2
Lifetime risk of CRC ~60%; endometrial cancer ~40-60% Risk is markedly lower if colonoscopies begin early

Lynch Syndrome Clinical Features
Striking family history affecting multiple generations
Early (but variable) age at CRC diagnosis (mean 45 years)
Multiple primary cancers Extracolonic cancers:
Endometrium Ovary Urinary tract Stomach small bowel sebaceous carcinomas of skin
Lynch Syndrome• Sine qua non is identification of a germline mutation
• Families originally identified based on Amsterdam Criteria (AC-I)
• ≥ 3 cases of CRC• ≥ 2 generations affected• at least one CRC< 50 years• no evidence of FAP
• 50% of AC-I families do not have a MMR mutation• Testing only those who meet AC fails to detect 50%
Clinical Criteria for the Identification of Lynch Syndrome
• Revised Bethesda Guidelines– Incorporates MSI testing, extracolonic cancers– Cumbersome criteria to apply regularly which makes
uptake low– Testing those who meet any of the Bethesda criteria would
fail to detect 30% of gene mutations carriers
Lynch syndrome and EAO-CRC
• Lynch syndrome accounts for 3-4% of ALL CRCs, regardless of ages
• What % of EAO-CRC is due to Lynch syndrome?
• Few studies have examined random samples of the prevalence among CRC patients <50 years
Lynch syndrome and EAO-CRC
• US study examining the prevalence of Lynch syndrome – Unselected, population-based sample– Young-onset CRC cases diagnosed <50 years– Identified through the CCFR
• Results: 195 eligible subjects– Mean age of diagnosis: 43 years– 5.6% (11/195) had MMR gene associated with
Lynch syndromeLimburg PJ et al. Clin Gastroenterol Hepatol. 2011;9(6):497-502
Lynch syndrome and EAO-CRC
• Spanish study examining the prevalence of Lynch syndrome – Unselected, population-based sample– Young-onset CRC cases diagnosed <50 years– Identified through 2 surgical centers in Spain
• Results: 140 eligible subjects– Mean age of diagnosis: 44.1 years– 7.8 (11/140) had MMR gene associated with
Lynch syndromeGiraldez MD et al. Clin Cancer Res. 2010; 16: 5402-5413.
Summary of Lynch syndrome and contribution on EAO-CRC
• 3-4 % of all CRCs, regardless of age, are due to Lynch syndrome
• 6-8% of EAO-CRC are due to Lynch syndrome
• Largest impact for at-risk individuals– Early identification of mutation carriers prevents
cancer

Thibodeau, PhD; Lisa A. Boardman, MD; Daniela Seminara, PhD, MPH
Ability to define new conditions from existing ones
• Families fulfill AC-I criteria – Suspected Lynch syndrome but no mutation
• Lower CRC incidence than Lynch syndrome– SIR 2.3 (1.7-3.0) vs SIR 6.1 (5.2-7.2)
• Incidence may be lower for other cancers• Families should not be described or counseled
as having Lynch syndrome • Lynch Syndrome ≠ Familial CRC Type X
Familial Colorectal Cancer Type X
• Genetic etiology is largely unknown– Has a monogenic component
• likely caused by high-penetrance mutations
– ?Polygenic component: Is there an interaction of multiple low-penetrance genetic variants
• Clinical characteristics such as lower risk of CRC and fewer associated extracolonic cancers suggest this
• More similar to sporadic CRC?
• Represents a novel form of familial CRC and families are resource for research
Familial Colorectal Cancer Type X
HOWEVER….• Phenotype varies from “classic” to “attenuated”• 30% are de novo cases: no family history
• Classic FAP easy to recognize• Penetrance for adenomas and
cancer near 100% in APC+ gene mutation carriers
Familial Adenomatous Polyposis
Variations of classic phenotypes are common: Attenuated FAP
• Attenuated polyposis is a phenotypically distinct variant of FAP
• Arises from mutations in proximal or distal portions of APC gene
Characteristics
• Mean age at CRC diagnosis: 54 years • Cumulative risk of CRC by the age of 80 yr is ~69%• Proximal>>distal colon polyps and 75% of tumors occur in the
proximal colon
*The prevalence of APC mutations is likely similar in EAO-CRC*
• Polyp phenotype more so “attenuated”• Autosomal recessive pattern of inheritance• Biallelic mutation carriers: 53 fold excess risk of CRC• Up to 80% increased risk of CRC in lifetime• Monoallelic mutation carriers: OR 1.15• Mutational hotspots:
–White, Northern Europeans : Y165CG382D
– Indian/Pakistani: E466X
MYH associated polyposis (MAP): A newer entity in inherited CRC risk
account for 80% of all mutations
Jenkins MA, et al. Cancer Epidemiol Biomarkers Prev 2006; 15:312-4Win AK, et al. Fam Cancer 2011; 10:1-9
MYH associated polyposis
• ~3% of EAO-CRC is due to MYH mutations– Compared to <1% of all CRC cases, regardless of
age• ~30% of biallelic MYH carriers develop CRC
without polyps – According to population-based studies
• Recommendation that all early-onset CRC should be tested for MUTYH mutations

Stepwise Approach for Inherited CRC Syndromes
• Requires recognition of cancer syndromes by providers–Diagnosis may be missed–Additional genes with other cancer syndromes increase
CRC risk • Time consuming process, multiple decisions
–Test and re-test–Complex decision-making for patients
Germline p53 Mutations and Early Age Onset Cancers
• Li-Fraumeni syndrome – caused by p53 mutations
• Lifetime risk of cancer is ~70-100%• Carriers develop early onset cancers
– Leukemias, brain tumors, sarcomas, breast cancer, adenocortical cancers
– Reports of gastric and CRC
• 457 patients with CRC ≤40 years old• 1.3% carried a p53 gene mutation
– Comparable to the prevalence of APC gene mutations associated with FAP
• None of the patients met clinical criteria for Li-Fraumeni Syndrome
Advances in Genetic Testing for Inherited CRC
• Next Generation Sequencing (NGS) allows for simultaneous assessment of many cancer susceptibility genes with multi-gene panel testing: – Breast, colon, ovarian, pancreas….
• The role of NGS panel testing and its yield over traditional genetic testing strategies are unclear
• Will change the conventional approach to genetic evaluation

Summary & Future Directions
• 85 % of EAO-CRC are not explained by known inherited CRC syndromes
• NGS Panel testing will redefine the contribution of known cancer-related genes in EAO-CRC
• Continued research efforts are necessary in affected individuals and family members– Gene discovery– Screening and surveillance recommendations

Hereditary CRC risk
• familial cases comprise approximately 30% of all CRC
• mutations in highly penetrant CRC susceptibility genes account for 5-10% of all CRC
• etiology of remaining 20-25% of inherited CRC is not completely understood

Gut microbiome and CRC
• Gut microbiome plays key roles in inflammation and in the breakdown of otherwise indigestible food compounds, such as fiber.
• Animal studies (Infect Immun 1998, mBio 2013)
- mice develops fewer colon tumors under germ-free conditions - fecal transplant from CRC mice results in tumor formation
• Systematic epidemiologic surveys of gut microbiome with cases and controls are lacking.
• We tested the hypothesis that altered gut microbiome is associated with risk of CRC.

Fusobacterium increases CRC risk
• Multivariate OR=3.74, p=0.0035.
• Fusobacterium is gram negative inflammatory bacteria.
• Consistent with our result, two studies reported that Fusobacterium is enriched in human colorectal cancer tissue compared to adjacent normal tissue
(Genome Research 2012 and Science 2013).
Ahn et al, JNCI, 2013
173
Clostridia decreases in CRC patients
• Clostridia depleted in CRC cases (Multivariate OR = 0.8, P=0.005).
• Clostridia ferment dietary fiber to short chain fatty acid
(butyrate),anti-carcinogenic components.

• However…………..• At least 75% of EAO-CRC patients DO NOT
report positive family history of the disease
• Dr Kastrinos shared Dr Limburg’s Colorectal CFR data indicating less than 6% of < 50 patients carried a Lynch Syndrome gene mutation.

“You Never Know…”
Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge
• We know a great deal• There are clear opportunities to use
that knowledge to inform patient choice and provider response / action.
• Knowledge of RISK FACTORS can be immediately deployed to RISK REDUCTION strategies.
Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge
• Known RISK FACTORS need to be validated in YOUNG ADULTS.
• Tackling UNKOWNS – requires resourcing our national / international cancer registries to address the problem
• EAO-CRC Survivor Survey Project

Cancer Survivorship
• Cancer survivorship = the state or process of living after a diagnosis of cancer
• Encompasses not only the physical but also the social, psychological, and spiritual/existential impact of cancer on one’s life and for the remainder of one’s life.
Measuring Quality of Life
• Physical functioning• Health status• Sexuality and fertility• Emotional adjustment• Psychological and
behavioral functioning• Spiritual/existential
domains
• Future outlook• Independence• School performance• Work performance• Social relationships• Family relationships
• Establish autonomy and independence– Achieve emotional independence from adults– Self-esteem and identity development– Acquire a set of values and an ethical system as a
guide to behavior• Social and intimate relationships
– More mature relations with peers– Prepare for marriage and family
• Establish financial independence– Completion of school– Prepare for a career.
Crucial Developmental Milestones in Young Adulthood
The Impact of an Illness
• Changes in mobility and physical functioning
• Changes in physical appearance• Separation from peers and usual activities• Increased dependence on parents at a
time they would usually be practicing independence
Research on Quality of Life (QOL) in
Young Adult Cancer Survivors
N=523 young survivors, age 15-39• Compared to peers, YCS had lower physical
and social functioning; psychosocial, emotional, and work/school functioning were similar to peers
• Worse HRQOL associated with: < high school, no insurance, Hispanic ethnicity, active treatment (esp. chemo), younger age, greater symptom burden
• Demands of normal physical, hormonal, cognitive changes + other normal developmental changes may contribute to lower levels of physical functioning and fatigue
Smith, JCO, 2013
Health-related QOL in Young Cancer Survivors
N=8375 survivors, diagnosed age 15-39
• Compared to peers, 30% of those age 40-64 reportpoor/fair health vs. controls
• > 1 diagnosis associated with poorer QOL• 45% of female CRC survivors report fair/poor health
– Long-term issues with infertility, bowel function• Earlier age of diagnosis associated with more
days of poor mental health compared with older age at diagnosis– Gap in psychological support for youngest survivors
• Young age at diagnosis may have long-term QOL impact across lifespan
Kirchhoff, JAYAO, 2014
Health-related QOL in Young Cancer Survivors
• About half or fewer may achieve recommended levels of physical activity (PA)
(ages 20-44)• About half may be overweight or obese• More physically active compared to older
survivors, less compared to age-related peers
• Benefits of PA include improved QOL, symptom reduction, and improved survival/reduced recurrence risk in some cancers
• Tobacco use may be higher compared to older survivors

– Side effects and symptoms• Fatigue, depression, nausea, weight gain/loss, bowel function,
sexuality/fertility, changes in eating, decreased energy, body image concerns
Zebrack, Psychosoc Onc, 2014
QOL Domains for Young Cancer Survivors
• Practical– Financial
• Inadequate or gaps in health insurance• Difficulty navigating health insurance coverage• Work interruptions• Acquiring early debt & limited financial resources
– School/ work disruption• Treatment takes precedence over work, school
QOL Domains for Young Cancer Survivors
• Psychological and Spiritual– Managing distress & emotions related to
cancer,treatment, and fear of recurrence
– Social functioning and isolation• Disclosure and communication
– Maintain/re-establish normalcy
– Loss: job/school, appearance change, relationship changes
***Positive attitudes, beliefs, feelings emerge from cancer experience
QOL Domains for Young Cancer Survivors
Cancer Can Promote Psychological Growth: Resilience Concept
• Some people can transform their lives by responding to an illness in ways that enhance the quality and meaning of their lives
• Resilience = process for identifying and developing resources or strengths to manage stressors in order to gain positive outcome from the experience
• Positive growth: greater maturity, appreciationfor life than population norms
• Racial/ethnic minority and medically underserved cancer survivors have greater disparities in cancer outcomes and access to survivorship care– African Americans: higher mortality for CRC– Uninsured or underinsured persons → more likely to
be diagnosed with advanced cancer → less likely to receive standard care and survive → less likely to adhere to surveillance and survivorship care regimens
• Uninsured/underinsured = predominantly Hispanic, recent immigrants, and the working poor
– Lifestyle behaviors (e.g., obesity, low physical activity, tobacco use) related to cancer recurrence or mortality are more prevalent among racial/ethnic minority, lower resourced, and less educated survivors
CDC, 2011; American Cancer Society, 2012
Health disparities in U.S. cancer survivors
Including “Previvors” in the Discussion About EAO-CRC
• Previvors = at increased risk of hereditary CRC, no CRC diagnosis• Bowel function and QOL in children with FAP who underwent
colectomyat age < 14 y
• n=28, 56% female, mean colectomy age=12 y, current age=24 y• Reported more night incontinence, nighttime stools (p<0.05); daytime
incontinence not different from adult sample• 60% reported feeling embarassed “always or sometimes” due to bowel
concerns• 20% reported restrictions at school or work, 30% restrictions in
sports due to bowel concerns• 36% worried ‘at least some’ about post-surgery cancer risk;
greaterin younger patients had greater worry
• Younger patients reported more FAP surgery-related distress– Number of FAP-affected family members associated with higher distress
• Body image and self-esteem scores in normal ranges

Clauser, 2011
• In general, young adult cancer survivors not well- represented in QOL studies of survivors– Especially EAO-CRC
• QOL needs for young adult survivors are specific anddiffer from older survivors
e.g., social functioning, financial stress, sexuality, health information
→ Need better understanding of QOL in EAO-CRC→ QOL measures specific to EAO-CRC→ Resources targeted toward specific QOL support
in EAO-CRC
Gaps and Opportunities
• Subgroups of young adult cancer survivors have specific needs– Those diagnosed at youngest ages– Underserved– Fertility, sexuality considerations– Pre-vivors
→ Need better understanding of life-stage specific QOL in EAO- CRC
→ Resources targeted toward specific QOLsupport in EAO-CRC
Gaps and Opportunities
• Health care system may not be responsive to needs of EAO-CRC– Cancer treatment settings may reflect pediatric vs. older
adult divisions in care– Delay in initial diagnosis and treatment, despite
persistent symptoms & health concerns• Delays in diagnosis → skepticism, mistrust →
pooradherence to treatment, failure to seek future care
→ Resources needed for EAO-CRC that areappropriate for varied stages of life, development
→ Support for providers who care for EAO-CRC e.g., Focus Under Forty (ASCO, Livestrong), EAO- targeted survivorship care plans and services

• Inadequate or gaps in health insurance• Difficulty navigating health insurance coverage
• Work interruptions• Acquiring early debt & limited financial resources
– School/ work disruption• Treatment takes precedence over work, school*QOL Domains for Young
Cancer Survivors
• Psychological and Spiritual– Managing distress & emotions related to
cancer,treatment, and fear of recurrence
– Social functioning and isolation• Disclosure and communication
– Maintain/re-establish normalcy
– Loss: job/school, appearance change, relationship changes
***Positive attitudes, beliefs, feelings emerge from cancer experience
*QOL Domains for Young Cancer Survivors
* Cancer Can Promote
Psychological Growth:
Resilience Concept
• Some people can transform their lives by responding to an illness in ways that
enhance the quality and meaning of their lives
• Resilience = process for identifying and developing resources or strengths to manage
stressors in order to gain positive outcome from the experience
• Positive growth: greater maturity, appreciation
for life than population norms
• Racial/ethnic minority and medically underserved cancer survivors have greater disparities in cancer outcomes
and access to survivorship care– African Americans: higher mortality for CRC
– Uninsured or underinsured persons → more likely to be diagnosed with advanced cancer → less likely to receive standard care and survive → less likely to
adhere to surveillance and survivorship care regimens
• Uninsured/underinsured = predominantly Hispanic, recent immigrants, and the working poor
– Lifestyle behaviors (e.g., obesity, low physical activity, tobacco use) related to cancer recurrence or
mortality are more prevalent among racial/ethnic minority, lower resourced, and less educated
survivorsCDC, 2011; American Cancer Society, 2012
*Health disparities in U.S. cancer survivors
* Including “Previvors” in the Discussion About EAO-
CRC• Previvors = at increased risk of hereditary CRC, no CRC diagnosis
• Bowel function and QOL in children with FAP who underwent colectomy
at age < 14 y• n=28, 56% female, mean colectomy age=12 y, current age=24 y
• Reported more night incontinence, nighttime stools (p<0.05); daytimeincontinence not different from adult sample
• 60% reported feeling embarassed “always or sometimes” due to bowelconcerns
• 20% reported restrictions at school or work, 30% restrictions in sports due to bowel concerns
• 36% worried ‘at least some’ about post-surgery cancer risk; greater
in younger patients had greater worry• Younger patients reported more FAP surgery-related distress
– Number of FAP-affected family members associated with higher distress
• Body image and self-esteem scores in normal ranges

• In general, young adult cancer survivors not well- represented in QOL studies of survivors
– Especially EAO-CRC
• QOL needs for young adult survivors are specific and
differ from older survivorse.g., social functioning, financial stress,
sexuality, health information
→ Need better understanding of QOL in EAO-CRC→ QOL measures specific to EAO-CRC
→ Resources targeted toward specific QOL support in EAO-CRC
*Gaps and Opportunities
• Subgroups of young adult cancer survivors have specific needs
– Those diagnosed at youngest ages– Underserved
– Fertility, sexuality considerations– Pre-vivors
→ Need better understanding of life-stage specific QOL in EAO- CRC
→ Resources targeted toward specific QOLsupport in EAO-CRC
*Gaps and Opportunities
• Health care system may not be responsive to needs of EAO-CRC
– Cancer treatment settings may reflect pediatric vs. older adult divisions in care
– Delay in initial diagnosis and treatment, despite persistent symptoms & health concerns•Delays in diagnosis → skepticism, mistrust →
poor
*adherence to treatment, failure to seek future care
*→ Resources needed for EAO-CRC that are
*appropriate for varied stages of life, development
* → Support for providers who care for EAO-CRC e.g., Focus Under Forty (ASCO, Livestrong), EAO- targeted survivorship care plans and services

What Is “Normal” After Cancer Treatment?
Those who have gone through cancer treatment describe the first few months as a time of change. It’s not so much “getting back to normal” as it is finding out what’s normal for you now. People often say that life has new meaning or that they look at things differently now. You can also expect things to keep changing as you begin your recovery.
Your new “normal” may include making changes in the way you eat, the things you do, and your sources of support.
From Facing Forward: Life After Cancer Treatment – National Institute of Health; National Cancer Institute, May 2014
What is the ‘New Normal’ ?
• A paradigm shift
• A work in progress
• Part of a club you never wanted to join
• There is no new normal
• Nothing about the new is normal
• I am constantly reminded of my life before cancer
and it stings a little more as time passes
A New Normal: Patient Insight
• 175 patients, survivors and caregivers
participated
• Study and interviews conducted during January
and February, 2015
• In person meetings; virtual town hall meetings;
telephone; and social media private chats
