Evidence-Based Practices for Hereditary Breast and Ovarian Cancer Syndrome and Lynch Syndrome 1
Slide 2-

Overview What are Hereditary Breast and Ovarian Cancer syndrome (HBOC) and Lynch syndrome (LS)? How common are LS and HBOC? How do LS and HBOC affect individuals and families? How do I identify individuals at risk and their families? What should I do after I identify a patient at risk? What should I do after a patient is diagnosed? 2
Slide 3-

Hereditary Breast and Ovarian Cancer Syndrome (HBOC): An Overview Individuals with HBOC have a significantly increased risk for breast, ovarian, and other cancers. Identifying individuals with HBOC is important because steps can be taken to reduce future cancer risks for patients and their relatives. 3
Slide 4-

BRCA-Associated Hereditary Breast and Ovarian Cancer Syndrome Caused by inherited changes in BRCA1 and BRCA2 genes Increased risk for breast, ovarian, and other types of cancer (high grade prostate, male breast, pancreatic) Certain ethnic groups are at increased risk for BRCA mutations 1 in 40 Ashkenazi Jews Interventions can significantly reduce risk of cancers 4

Screening Tumor Tissue for Lynch Syndrome For individuals newly diagnosed with colorectal cancer, tumor screening is often done before genetic testing Less complicated Less expensive Identify patients for genetic testing Guide which genes to include in genetic testing 26
Slide 27-

Screening Tumor Tissue for Lynch Syndrome Immunohistochemistry (IHC) or Microsatellite Instability (MSI) screening Screening tests, not diagnostic tests Identify those more likely to have Lynch syndrome but further testing needed for diagnosis of Lynch syndrome Can be done individually or in combination Some institutions may decide to perform IHC and/or MSI testing on newly diagnosed endometrial cancers Source: National Comprehensive Cancer Network. NCCN Guidelines Version 1.2017 Genetics/Familial High-Risk Assessment: Colon. 27
Slide 28-

Immunohistochemical (IHC) Screening Mutations in mismatch repair genes result in loss of expression of 1-2 of the mismatch repair proteins in tumor tissue IHC involves staining tumor tissue for protein expression of the Lynch syndrome-related mismatch repair genes: MLH1, MSH2, MSH6, and PMS2 Absence of staining in tumor tissue = loss of protein expression If screen positive, referral for genetic counseling and diagnostic germline mutation analysis About 20% CRC tumors have abnormal IHC, not all Lynch 5-15% false-negative rate Not useful screen for other hereditary colon cancer syndromes This tumor sample has absent staining of MLH1 and PMS2 proteins http://www.lynchscreening.net/implementation/immunohistochemistry-ihc-only-2 Source: National Comprehensive Cancer Network.

Slide 29-

Screening Tumor Tissue for Lynch Syndrome: BRAF Testing BRAF mutations present in 15% of colorectal cancers BRAF mutations can inhibit MLH-1 expression so absent MLH-1 and PMS2 expression in IHC screening could be due to BRAF mutations BRAF mutations are not associated with Lynch syndrome and are consistent with sporadic, not inherited, colorectal cancer Molecular genetic testing for somatic BRAF mutations can help rule out Lynch syndrome in individuals with absent expression of MLH1 and PMS2 in IHC screening For Endometrial Cancers: BRAF testing is not helpful in distinguishing sporadic vs. Lynch syndrome-related cancers Kohlmann W, Gruber SB.

IHC Testing Algorithm
Slide 31-

Microsatellite Instability (MSI) Testing Compares areas of repeated DNA, called microsatellites, in the tumor tissue to normal tissue to determine if the mismatch repair genes associated with Lynch syndrome are working properly 5-15% false-negative rate Possible results MSI-High (MSI-H): microsatellite unstable, patient may have Lynch syndrome Additional testing to determine if result is due to Lynch syndrome (IHC, MLH1 hypermethylation testing, or DNA testing) MSS (MSI-Low): microsatellite stable, patient likely does not have Lynch syndrome Source: National Comprehensive Cancer Network.

Family Health History Screening and Risk Assessment 35
Slide 36-

Family Health History Screening and Risk Assessment Health care providers should ask the following questions when taking a family health history: Do you have any relatives who have been diagnosed with cancer? Be sure to ask about parents, brothers, sisters, children, grandparents, aunts, uncles, nieces, and nephews For each relative with a diagnosis of cancer What type(s) of cancer did the relative have (note multiple primaries)? What was the specific pathology of the cancer (if known)? Is the tumor available for testing (if colorectal or endometrial cancer)? At what age was the relative diagnosed with cancer? Family ethnicity/country of origin 36

Genetic Counseling for Hereditary Breast and Ovarian Cancer Syndrome and Lynch Syndrome 43
Slide 44-

What Do I Do After I Identify a Patient as At-Risk? Refer for genetic counseling Provide education regarding the genetics of cancer and the likelihood of developing cancer Discuss risks, benefits, and limitations of genetic testing Review appropriate cancer screening and prevention strategies NSGC Practice Guideline: Risk Assessment and Genetic Counseling for Hereditary Breast and Ovarian Cancer: J Genet Counsel (2013) 22:155-163. 44
Slide 45-

Who Can Provide Genetic Counseling? Several professional organizations describe skills and training needed for comprehensive genetic counseling National Society of Genetic Counselors American College of Surgeons Commission on Cancer 45
Slide 46-

Who Can Provide Genetic Counseling? National Society of Genetic Counselors Certified Genetic Counselors Have Master’s-level education through accredited program Passed certification exam Meet other requirements of American Board of Genetic Counseling Certification and licensure requirements differ by state Search for a genetic counselor by specialty and location at http://www.nsgc.org/ 46
Slide 47-

Who Can Provide Genetic Counseling? American College of Surgeons Commission on Cancer Standard 2.3. Risk Assessment and Genetic Counseling Genetics professionals include American Board of Genetic Counseling or American Board of Medical Genetics board-certified or licensed genetic counselor American College of Medical Genetics physician board-certified in medical genetics Genetics Clinical Nurse or an Advanced Practice Nurse in Genetics credentialed through Genetics Nursing Credentialing Commission Board-certified physician with experience in cancer genetics (defined as providing cancer risk assessment on a regular basis) Advanced practice oncology nurse with specialized graduate education in cancer genetics and hereditary cancer predisposition syndromes; certification by the Oncology Nursing Certification Corporation preferred Educational seminars offered by commercial laboratories about how to perform genetic testing not considered adequate training for cancer risk assessment and genetic counseling 47
Slide 48-

Why is Genetic Counseling Essential? Ensure full informed consent Address patient’s and families’ concerns Review differential diagnosis Assess best strategy to test the family Obtain records (on other family members), pathology, detailed family health history Interpret results accurately Positive, negative, variant of unknown significance Increase the likelihood that correct surveillance is recommended Coordinate testing for family members 48
Slide 49-

Cascade Screening An active process to find relatives of person affected with certain genetic conditions at a pre-symptomatic stage because interventions exist that can save lives An example of cascade screening for HBOC: 49
Slide 50-

Risks to Family Members BRCA- and Lynch syndrome-associated genetic changes are almost always inherited from a parent First degree relatives (parents, siblings, children) of an individual diagnosed with a BRCA or Lynch syndrome-associated genetic change have a 50% risk of having the same genetic change Second, third, and more distant relatives are also at risk to have the same genetic change Relatives who do not have the genetic change identified in the family cannot pass it on to their children 50
Slide 51-

Genetic Testing in Relatives First person tested in family should have had breast or ovarian cancer (for BRCA testing) or colorectal or other Lynch syndrome-related cancer (for Lynch syndrome testing) whenever possible Full gene sequencing of one or more indicated genes Testing for founder mutations if Ashkenazi Jewish or Eastern European ancestry Identify specific genetic change in the family Relatives should have genetic testing for the specific genetic change identified Single Site testing or Site-specific testing Significantly less expensive 51
Slide 52-

Continuity of Care Continuity of care is essential and includes Continuing contact with patients, inquiring about changes in family history Asking carriers about other family members considering genetic counseling Discuss new testing techniques, changes in variants of uncertain significance 52
Slide 53-

When Can Genetic Evaluation Be Done? After identification of risk (significant family health history) After cancer diagnosis Concomitant with diagnosis and treatment discussions During treatment, including chemotherapy After treatment Months, years later, when other family members become concerned 53
Slide 54-

Affordable Care Act Affordable Care Act (ACA) requires many health plans to provide in-network coverage without cost-sharing for preventive services with a USPSTF rating of “A” or “B” B rating for BRCA screening recommendation Genetic counseling, if appropriate, is covered in-network without cost sharing when used in accordance with the USPSTF recommendation Department of Health and Human Service clarified in 2013 that the BRCA test itself, if appropriate, is within the scope of the USPSTF recommendation and should be covered in-network without cost sharing Applies to non-grandfathered health plans and health insurance coverage offered in the individual or group market *Billing practices for genetic counseling vary by institution and may affect coverage http://www.cms.gov/CCIIO/Resources/Fact-Sheets-and-FAQs/aca_implementation_faqs12.html https://www.healthcare.gov/preventive-care-benefits/women/ 54

Management Options for Hereditary Breast and Ovarian Cancer Syndrome and Lynch Syndrome 55
Slide 56-

Interventions for Women with BRCA1 and BRCA2 Mutations Several management options exist but the strength of evidence varies across types of interventions USPSTF recommends: Risk-reducing bilateral mastectomy 85-100% reduction in breast cancer risk Risk-reducing oophorectomy or bilateral salpingo-oophorectomy (BSO) 69-100% reduction in ovarian cancer risk 37-100% reduction in breast cancer risk Chemoprevention Tamoxifen or raloxifene U.S. Preventive Services Task Force.

Bidirectional Cancer Registry Reporting for the Identification of Individuals at Risk for Hereditary Breast and Ovarian Cancer Syndrome and Lynch Syndrome 61
Slide 62-

Cancer Registries All states maintain central cancer registries in accordance with state laws All cancers diagnosed in a state are reported to that state’s central cancer registry Cancer registrars at each institution collect information required by the state to submit to the state registry, including: Demographics Information about cancer diagnosis Treatment information 62
Slide 63-

Cancer Registries State central cancer registry data are used for Identifying trends Public health purposes Approved research Patient information is kept confidential Only reported in aggregate, without patient identifiers IRB approval required for research using cancer registry data 63

Slide 65-

Bidirectional Cancer Registry Reporting A two-way exchange of information between the state cancer registry and reporting institutions Cancer cases reported to state registry by institution State cancer registry uses national guidelines to identify cases with increased risk for HBOC or LS State compiles these cases and associated informational materials for providers and patients State sends this information back to institution 65
Slide 66-

Information Provided Through Bidirectional Cancer Registry Reporting Number of patients identified as being potential candidates for genetic evaluation for HBOC or LS Information for providers about HBOC and LS Summary of patient management recommendations List of cancer genetic counseling services in the state Patient educational materials about HBOC and LS Information to assist patients with sharing information about their HBOC or LS diagnosis with family members 66

Slide 69-

How Bidirectional Cancer Registry Reporting Can Improve Patient Health Identifies patients who are potential candidates for genetic counseling and testing for HBOC and LS Allows for identification of at-risk relatives of individuals with HBOC or LS through cascade screening Provides patients and their family members with information for primary and secondary prevention of cancer in the future, if patients are contacted as part of bidirectional reporting program Aids providers in personalizing screening and prevention plans for patients and their family members, if providers receive information on individual patients Increases awareness of national guidelines for HBOC and LS 69
Slide 70-

[State’s] Bidirectional Cancer Registry Reporting Program [Use this slide to describe the program being implemented in your state. For example, who will be receiving information from the cancer registry and in what format? What patients will be identified? Will providers have access to specific patient names? Etc.] 70
Slide 71-

Bidirectional Cancer Registry Reporting: Limitations Bidirectional reporting will not identify all patients who meet national guidelines Most state cancer registries do not collect family history information, so patients with a significant family history of cancer may not be identified. Providers must continue to be vigilant in identifying these patients through careful family health history collection. Lag in registry data (2+ years) so most individuals will be finished with treatment at the time they are identified. Reporting physician information is not always reliable, and provider may no longer provide care for patient. Reporting institution might be where patient got diagnosed and not where they received care or routinely see doctors. Reports sent to institutions may not be seen by providers. 71

Information for Patients and Families
Slide 73-

Brochure Talking to Your Family About Your Diagnosis of Lynch Syndrome When you share information with people, sometimes they feel helpless and don’t want to address it. I used to have that mentality, too. After my genetic testing, the genetic counselor asked if I wanted to come in to talk about my test results or if I would rather have them over the phone. I wanted it quick like a band-aid. At that moment, my life changed: I was positive for Lynch syndrome. I could not ignore it anymore. Now there’s always the question, where do you go from here? Because it’s not something you get better from. That is the most difficult part of explaining to people what Lynch syndrome is and what it means for the future. Why Talk to My Family? Your family members can benefit from knowing about your diagnosis of Lynch syndrome. Talk to your family members about Lynch syndrome, so that they will know that: Lynch syndrome is passed through families. A person with Lynch syndrome is more likely to get colorectal, endometrial (uterine), ovarian, and other cancers. Genetic counseling and testing for Lynch syndrome can provide information about their risk. If they choose to be tested, they should be tested for the same mutation that you have. Steps can be taken to prevent colorectal and other cancers or find them earlier. IT’S NOT EASY... ...but talking about Lynch syndrome is one of the most important things you can do to protect your family. Judi’s Story Insert Your Logo/Organization Info Here

What if My Family Does Not Want to Talk? Talking to some family members about Lynch syndrome might not be easy. Some might not understand why they need to know this information. Others might be nervous about receiving a diagnosis of Lynch syndrome. Remember that family members need to make their own choices about getting tested, whether or not you agree with their decisions. If family members don’t want to talk about Lynch syndrome, respect their wishes. Let them know you are available to talk if they have questions, and give them places to find information. When family members do not want to talk about Lynch syndrome, you might feel upset or alone. Seek support from friends, healthcare providers, other family members, or people you know with Lynch syndrome. Where Can I Find More Information? You can find more information on Lynch syndrome at: www.ghr.nlm.nih.gov/condition/lynch-syndrome You can find information on support groups for Lynch syndrome at: http://www.diseaseinfosearch.org/Lynch+syndrome/3371 How Do I Talk to My Family About My Lynch Syndrome Diagnosis? WHO: Your parents, siblings, and children are the family members who are most likely to have Lynch syndrome. Other blood relatives, such as aunts, uncles, nieces, nephews and cousins, are also more likely to have Lynch syndrome. Your healthcare provider or genetic counselor can help you figure out who in your family might have Lynch syndrome and thus would benefit from knowing about your diagnosis. WHAT: You can share test results, letters from your doctor or genetic counselor, or other information you received about your diagnosis with your family. Giving family members information about your specific genetic mutation helps their healthcare providers know exactly which test to use and might possibly save your family money. HOW: If you need extra support talking to your family, bring a friend. You can also ask a family member to attend your next medical appointment with you. The website http://kintalk.org can help you let your relatives know about your diagnosis and provides resources to help them learn more about Lynch syndrome. A sample letter that you can fill out and send to your family is available at www.cdc.gov/genomics/restoflink How Do I Talk to My Children? If you have Lynch syndrome, each of your children has a 50% (1 in 2) chance of having Lynch syndrome. Genetic testing for Lynch syndrome is typically not recommended for children younger than 18, but can be considered when your children reach adulthood. Younger children might not be able to understand what your diagnosis means for you or for them. Children differ in the age at which they are ready to learn about this information. Answer the questions they ask. They will ask more complex questions as they grow and are ready to learn more. Know that your children may have fears about the risk both to themselves and to you. Just as you need time and support to cope with the information and accept it, so will your children. Brochure 2
