29. 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

30. 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

31. Who else should begin screening before 50? Increased risk Age to begin Cancer/adenomas in a first-degree relative 40 years OR 10 years before youngest case Cancer in > 2 second-degree relatives 40 years

32. 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 bleeding 2. Abdominal pain 3. Change in bowel habits • Critical need for further research to elucidate the cause of this trend

45. 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.

84. 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

85. 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%

86. 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

87. Lynch Syndrome Results From Failure of Mismatch Repair (MMR) Genes Base pair mismatch Normal DNA repair Defective DNA repair (MMR+) T CTA C A G C T G T C G A C A G C T G T CTA C A G C T G A G A T G T C T A C

88. Mismatch Repair Failure Leads to Microsatellite Instability (MSI) Normal Microsatellite instability Addition of nucleotide repeats

89. 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

90. 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%

91. 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

92. 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

93. 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 syndrome Limburg PJ et al. Clin Gastroenterol Hepatol. 2011;9(6):497-502

94. 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 syndrome Giraldez MD et al. Clin Cancer Res. 2010; 16: 5402-5413.

95. 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

99. • 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

100. • 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

101. 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

102. 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*

103. • 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 : Y165C G382D –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; 15:312-4 Win AK, et al. Fam Cancer 2011; 10:1-9

104. 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 Riegert-Johnson DL et al. Genet Test. 2007;11:361–365. Giraldez MD et al. Clin Cancer Res. 2010; 16: 5402-5413.

105. Germline Testing Proband HEREDITARY GI CANCER SYNDROME Pedigree Clinical Criteria +/- tumor testing + 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

106. 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

107. • 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

108. 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

115. 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

160. 16 5 • Recently completed study of microbiome and colorectal cancer - published in Journal of National Cancer Institute • Large scale on-going effort on - NYU Human Microbiome Study Cohort Overview of talk

161. 16 6 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.

162. 16 7 • Hospital based case-control study - 47 CRC cases and 94 non-cancer controls - recruited 3 hospitals in Washington DC area - matched by age, gender, and BMI • Diet and demographic questionnaires • In-home 2 day fecal collection • 16s rRNA gene sequencing microbiome assay Study Design

163. 16 8 Microbiome Assay and Data Analysis - Compared overall gut microbiome diversity and microbial taxa abundances in CRC cases and controls

166. 17 1 Taxonomic differences in CRC and controls Case Cont Ahn et al, JNCI, 2013

167. 17 2 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

168. 17 3 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. Ahn et al, JNCI, 2013

169. 17 4 High fiber intake decreases CRC risk 0.6 0.7 0.8 0.9 1 1.1 CRC Risk <15 g/day, 15-20 g/day, 20-24 g/day, 24-30 g/day 30+ g/day Dietary Fiber Intakes Lancet 2003, JAMA 2005 • Non-digestible plant component of complex carbohydrates

183. Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge • For almost a quarter of a century our collective “conditioned reflexes” have been wired to think “genetic hereditary syndrome” when we see a young (under 50) solid tumor patient in general and especially with breast and colorectal cancer. • However…………..

185. Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge • 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.

186. Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge • So………….. • We are facing a new problem… • A Fresh Challenge….... • A novel opportunity to advance our understanding of the basic biology of the pathophysiology of solid tumor malignancy in the young.

187. Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge • I have no links whatsoever to this man…

188. However NO RELATION!

189. HOWEVER…… Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge • A Potentially Useful Construct: • “There are known knowns. These are things we know that we know. • There are known unknowns. That is to say, there are things that we know we don't know. • But there are also unknown unknowns. There are things we don't know we don't know.”

190. Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge Known Knowns……The Basics • Health Insurance: what are the dimensions of this problem? What specific strategies could address this? Do related pre-existing issues impact it” • No Primary Care Physician: again – the dimensions? • Remember – in NYC > 80% unscreened had insurance AND a primary care physician

216. Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge SUMMARY?

217. Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge “You Never Know…”

218. 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.

219. 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

220. Early Age Onset Colorectal Cancer A 21st Century Epidemiologic Challenge RISK • Identification • Clarification • Mitigation / Reduction

224. 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.

225. 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

226. • 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

227. 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

228. Research on Quality of Life (QOL) in Young Adult Cancer Survivors

229. 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

230. N=8375 survivors, diagnosed age 15-39 • Compared to peers, 30% of those age 40-64 report poor/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

231. • 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 Health Behaviors in Young Adult Cancer Survivors

234. • Medical care – Perceived excellence in care after diagnosis – Dissatisfaction with initial diagnosis delay • Patient factors - still-maturing cognitive function, reliance on peers for information • Provider factors – not attributing symptoms to cancer, poor provider-patient communication – 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

235. • 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

236. • 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

237. 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

238. • Racial/ethnic minority and medically underserved cancer survivors have greater disparities in cancer outcomes and access to survivorship care – AfricanAmericans: 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

239. 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); 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; 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 Durno, Dis Colon Rectum (2012)

243. • 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 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

244. • 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 QOL support in EAO-CRC Gaps and Opportunities

245. • 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 Gaps and Opportunities
