.style1 { text-align: center; } THE VERY FIRST LINE OF DEFENSE IN THE SURVIVAL OF LYNCH SYNDROME IS KNOWING ONE'S FAMILY HISTORY Lynch syndrome is inherited through families in an autosomal dominant manner. This means an inherited mutation of the mismatch repair gene, coupled with a normal gene will produce children that have an estimated 50-50 chance of contracting Lynch syndrome. The ONLY way to diagnose Lynch syndrome effectively is first through a careful review of the family history. What the physician is looking for are three individuals, two of which are directly related to the third and who have sustained a Lynch cancer. (Colorectal Cancer, Endometrial Cancer, Gastric Cancer, Ovarian Cancer, Hepatobiliary Cancer, Pancreatic Cancer, Ureter Cancer, Renal Pelvic Cancer, Skin Cancer (Muir Torre), Prostate Cancer, some subsets of Breast Cancer and Brain Cancer.) This basically leads the physician to determine whether or not to prescribe genetic counseling and/or genetic testing which, if positive, allows individuals diagnosed with Lynch syndrome to obtain annual screening tests to detect cancers early, when they are often treatable and not life threatening. Generations of a Lynch Syndrome Family - A Personal Story Knowing family histories and sharing them with physicians not only helps protect us in avoiding certain hereditary illnesses and predispositions to chronic conditions but alerts us to possible complications which could occur during surgeries and conditions which can affect recovery. An added benefit is it allows us to learn of family traditions and stories of the trials and tribulations of our ancestors which can also greatly assist in achieving a strong recovery and survivorship. A good first step toward this process is to view the free, public resource available through the Surgeon General's Family Health Initiative addressing documenting your family history. Their site has software available for use to document and print out the family history for family members and the health care provider. In addition, it has the capabilities for the family history to be downloaded into the medical file in your physician's office. After reviewing it carefully, sit down with your parents and ask them their medical backgrounds, questions about their lives. Where were they born? What ethnicity were they and their ancestors? How and where did they grow up? Were they raised in the city or on a farm--in a small town or in a major metropolitan area? How did they get their water -- from a well, or a municipality? What did they eat and how was it prepared? What was their life like? Did they work in factories or spray crops? When and where were they born? Were they ever ill or hospitalized? Did they contract any cancers? At what age? If so, where was the cancer located? Where were they treated? These questions are extremely important as environmental factors have every bit as much of an effect on cancers as hereditary factors and can provide clues into what familial or inherited cancer condition one may have. Everything is interrelated when it comes to cancer. Therefore, list every occupation, every situation, everything those ancestors did and when, where and at what age it occurred. Ask about their parents, grandparents, brothers and sisters, nieces and nephews and pose the same questions you asked about your parents' past and lifestyles. Every answer they provide will render little clues as to the information you will need to protect yourself and your family. In many families, adults and other family members have often kept health matters private and may at first appear uncomfortable about answering these questions. It is important to ask the right questions and to prompt them and job their memories as to where there was removal of colon polyps, skin melanomas, abdominal surgeries, brain disorders and hysterectomies. Be certain to document each and every one. When documenting the family history, don't forget to ask about hysterectomies. Today, one of three women have had a hysterectomy. This information can significantly provide clues or information to create a direct relationship as endometrial cancer may be equally as prolific in Lynch syndrome as colorectal cancer. Its also not unusual for family members to have little or no knowledge of how grandparents, aunts and uncles or cousins died so simply ask them when and where...then go to the local library or newspaper office and research the obituary or pull the death certificate from the state or country department of vital records. When preparing a family history, its a good practice to not limit one's self strictly to Lynch syndrome, but to document every possible condition parents, siblings, children, grandparents, aunts, uncles, nieces, nephews, cousins and ancestors could have had. This process is often eye opening and can provide a totally new perspective in respect to other potential unknown health conditions. While performing research upon our ancestors and related family members, it only helps us to learn not only how they died but what our ancestors endured in life. This can prove invaluable toward our own sense of survival. The characters of our ancestors can serve as clues as to how they survived unthinkable conditions. Those clues may dramatically help us weave our way through the survival process. In reflecting upon how they lived and managed despite incredible adversity, we can draw from their strength. Once the family history is provided to the doctor, he/she will assess it and by the use of online tools or by expertise, will determine the level of risk for inherited conditions and whether or not to refer you to a genetic counselor or grant a direct referral for genetic testing. The taking of a family medical history is considered a "standard of care," taught to all physicians at all medical schools and is considered "good medicine." However in today's quickly evolving technical world, there are an overwhelming number of things for physicians to know. Therefore, it is reasonable to assume your physician, gynecologist, urologist, dermatologist, obstetrician or pediatrician may not be aware of Lynch syndrome. We may have to provide our care providers with guidelines and resources so they may become familiar with it. A family medical history will assist health providers in not only determining risk and patterns that may be relevant to one's own health but also provide them with information to recommend prevention tools to reduce the risk of disease, decide what diagnostic tests to prescribe, assess whether or not genetic tests are necessary, diagnose a condition that may not otherwise have been considered, determine whether or not other members of your family are at risk for disease and other measures that could be life saving. The family medical history won't predict your future health but will allow you to know if you are at high risk for disease, life threatening or chronic conditions. The past provides clues to our futures so we and our families may remain happy, healthy and intact. Researching your family medical history is not only good sense and a loving thing to do, not only as parents, but as a responsibility of a patient to provide to the care provider.

    Women face additional risks of contracting cancer as a result of having Lynch syndrome, including an extremely high risk of endometrial cancer.  Endometrial cancer may be far more prevalent than previously thought and ongoing research is studying the prevalence. As well, women face an approximate 12% lifetime  risk of contracting ovarian cancer, which often appears symptomless and is difficult to diagnose at an early stage. Breast cancer has been identified as an integral component of LS, based upon mismatch repair germline mutation factors in breast cancer tissues from family members who are not only at high risk, but, moreover, who had Lynch syndrome cancers, such as involving the colorectum.  Breast cancer is exceedingly common in the population and, therein, its occurence in Lynch syndrome families could be due to chance, but importantly, a subset will likely be integrally related to a germline mismatch repair Lynch syndrome mutation in some LS families.  Therefore, it is prudent to mount a screening and management program for Lynch syndrome in those families where breast cancer is believed to be an integral lesion. (For more on breast cancer, visit the LSI Library for the up to date studies) Due to this, it is extremely important women consult with their gynecologist and schedule annual gynecological surveillance screenings, beginning between the ages of thirty to thirty five years of age. In addition to the annual PAP smear, the examinations should include: A pelvic exam; An endometrial biopsy; A vaginal ultrasound; A CA-125 blood test; Annual PAP smears; Annual mammograms; And if a family history of breast cancer exists, discussion with your physician as to whether an additional screening method is necessary.     Research into Lynch syndrome is relatively new and in the past there were not yet enough studies to determine evidence of the effectiveness or screenings.   These can be located at however, very little is stated regarding the women's cancers of Lynch syndrome. Australian and other international studies have explored the possibility of an association between Lynch syndrome and cervical cancer.  The jury is out as to whether or not there is a direct association and/or the extent of that association.  It is prudent to obtain annual PAP tests to insure early detection even if you have undergone a total hysterectomy with salpingo oopherectomy.   Forewarned is forearmed and in order to protect one's self, discuss creating an annual screening management program with your gynecologist.  For more detailed information on women's cancers and the women's risk, MD Anderson has outstanding resources upon their website.  Additionally, studies regarding Lynch syndrome women's cancers are available upon this site, under the LSI Library. Following child-bearing years, to reduce the risks of uterine and ovarian cancers, women with Lynch syndrome should seriously consider prophylactic (preventative) surgery to reduce the high risk of contracting endometrial and ovarian cancer.  This is especially important as often there are few or no symptoms of gynecological cancers and screening tests are not all that accurate in detecting women's cancers at an early stage.   The standard procedure utilized is referred to as a full abdominal hysterectomy with bilateral salpingo-oopherectomy (removal of the uterus, cervix, ovaries and fallopian tubes). As a result of modern technology, the surgery today is much easier for recovery and sometimes hospital stays are as short as 5 hours. Nonetheless, it is important to realize it is still a serious surgery and full recovery takes months. Prophylactic surgery, recommended following child bearing years, is often a "win-win" situation, protecting us from Lynch cancers and saving many women the "misery" of having to endure perimenopause, that up to ten year period of time prior to completion of menopause.   THE SURGICAL PROCESS Over 600,000 hysterectomies are performed each year and by the age of sixty, one in every three women, in the United States, has undergone hysterectomy.  Almost 90% of all the surgeries are elective (chosen) procedures, rather than lifesaving procedures.  A common practice, the majority of surgeons who perform hysterectomies are pretty experienced.

A TRIBUTE TO DR. HENRY T. LYNCH Lynch syndrome is about families and if anyone understands that, it is Dr. Henry T. Lynch, the founder. Today, many of us with Lynch syndrome exist, only as a result of this wonderful, caring man and his family who have given and sacrificed so very much so we and our families may live. Words can never express our gratitude but hopefully our global actions will. Our mission is to carry his mission forward for the generations to come--to work together as a team ---- survivors, previvors, medical professionals, genetics professionals, research professionals, governmental agencies, educational facilities, communities-- to find the over 600,000 individuals of which only 5% are diagnosed and to protect families and save lives from devastating cancers and to do so working within the true tradition of Dr. Henry Lynch. With Immense Gratitude For All He Has Done So Our Families May Live--- Team LSI Often referred to as the father of hereditary cancer, Lynch is a pioneer in the study of cancer and genetics. Part of the international team that discovered the location of one of two known genes involved in hereditary breast cancer, Lynch and his early cancer research significantly influenced how physicians and researchers treat and study hereditary cancers today. Lynch’s groundbreaking research in the 1960s into the medical history data of two extended families led him to the discovery of cancer family syndrome (CFS), also known as hereditary nonpolyposis colorectal cancer (HNPCC) or Lynch syndrome. Though not an actual cancer, Lynch syndrome strongly predisposes people who have this inherited defect to develop colorectal cancer as well as several other types of cancer. Lynch’s use of statistics to prove the genetic link to certain cancer types was unique from other researchers at the time. Born in Lawrence, Massachusetts on January 4, 1928, Lynch grew up in New York City. He joined the U.S. Navy at 16 using a falsified birth certificate and served in Europe, the Philippines and as a gunner on a marine ship in the Pacific during the Second World War. After being discharged from the Navy in 1946, Lynch stepped into the ring and became a professional boxer. He earned the nickname “Hammerin’ Hank” while boxing in upper New York State and in the San Francisco area. Lynch received his bachelor’s degree from the University of Oklahoma in 1951 and went on to earn his master’s degree in clinical psychology from the University of Denver in 1952. He received his doctorate degree in human genetics at the University of Texas, Austin, before completing medical school at the University of Texas, Galveston, in 1960. Lynch then interned at St. Mary's Hospital in Evansville, Ind. and completed his residency in internal medicine at the University of Nebraska College of Medicine in Omaha, Neb. Lynch was an assistant professor at the University of Texas M.D. Anderson Hospital and Tumor Institute in Houston prior to joining the Creighton University School of Medicine faculty in 1967. In 1984, Lynch established Creighton University's Hereditary Cancer Prevention Clinic, an interdisciplinary clinic that provides information and services related to hereditary cancers. He is currently chairman of Preventive Medicine at Creighton University, and the holder of the Charles F. and Mary C. Heider Endowed Chair in Cancer Research.
