Li-Fraumeni Syndrome

By Linda Athanasiadou

Genetics plays a fundamental role in the development and progression of cancer. As someone who has faced the challenges of cancer treatment, I, Linda Athanasiadou, have come to some thoughts on how our genetic makeup can significantly influence both the risk of developing cancer and the effectiveness of preventive measures. In this article, I will explore how genetics impacts cancer risk, the role of inherited mutations, and how understanding these genetic factors can inform prevention and treatment strategies. I am not a doctor, it’s just my personal research.

The Role of Genetics in Cancer

Cancer is caused by changes (mutations) in the DNA that lead to uncontrolled cell growth. While many of these mutations occur as a result of environmental factors, such as smoking, radiation, or diet, some mutations are inherited from one generation to the next. Inherited genetic mutations can significantly increase the risk of certain types of cancer, and understanding these genetic factors can be crucial for prevention, early detection, and treatment.

Genetic mutations that increase cancer risk are often classified into two categories: those that are inherited (germline mutations) and those that occur during a person’s lifetime (somatic mutations). Germline mutations are passed down from parent to child and are present in every cell of the body, while somatic mutations are acquired during a person’s lifetime and affect only specific cells.

Inherited Genetic Mutations and Cancer Risk

Some genetic mutations are directly linked to an increased risk of developing certain cancers. One of the most well-known examples is mutations in the BRCA1 and BRCA2 genes, which significantly increase the risk of breast and ovarian cancer. Women who inherit a BRCA mutation have a much higher lifetime risk of developing breast cancer, with estimates ranging from 45% to 70%, compared to about 12% in the general population. Additionally, men with BRCA mutations are also at increased risk for breast cancer and other cancers, such as prostate cancer.

In addition to BRCA1 and BRCA2, there are other inherited genetic mutations associated with increased cancer risk. For example, mutations in the TP53 gene, which is responsible for producing a protein that helps prevent the growth of tumours, can lead to a rare inherited disorder called Li-Fraumeni syndrome. This condition significantly increases the risk of developing several types of cancer, including breast cancer, bone cancer, and brain tumours, often at a young age.

Lynch syndrome, caused by mutations in genes involved in DNA repair, is another genetic condition that increases the risk of colorectal cancer and other cancers, such as endometrial and ovarian cancer. Individuals with Lynch syndrome have a much higher lifetime risk of developing these cancers compared to the general population.

Genetic Testing and Risk Assessment

Genetic testing has become an invaluable tool in assessing cancer risk. By testing for specific inherited mutations, healthcare providers can identify individuals who may be at higher risk of developing certain cancers. This information allows for targeted preventive measures, such as increased surveillance, lifestyle modifications, or even preventative treatments.

For instance, women who test positive for BRCA mutations may choose to undergo more frequent breast cancer screenings, including mammograms and MRI scans, starting at an earlier age. In some cases, individuals with a high genetic risk may opt for prophylactic surgeries, such as a mastectomy or oophorectomy (removal of the ovaries), to reduce the risk of cancer.

Genetic testing can also provide valuable information for family members, as they may share the same genetic mutations and be at increased risk for developing cancer. Understanding the genetic risk within families allows for early intervention and more effective prevention strategies.

The Role of Somatic Mutations in Cancer

While inherited genetic mutations contribute to cancer risk, most cancers are caused by somatic mutations, which occur throughout a person’s lifetime. These mutations are typically the result of environmental factors, such as exposure to carcinogens, UV radiation, or the natural aging process. Somatic mutations can affect specific genes that regulate cell growth, apoptosis (programmed cell death), and DNA repair.

In fact, many cancers involve mutations in genes that are responsible for controlling cell division and tumour suppression. For example, mutations in the TP53 gene, often referred to as the “guardian of the genome,” are common in many types of cancer, including lung, colon, and breast cancer. The loss of this tumour-suppressor gene can allow cancer cells to proliferate uncontrollably.

Somatic mutations can also be responsible for the development of resistance to cancer treatments. Over time, cancer cells can acquire mutations that enable them to evade the effects of chemotherapy or immunotherapy. This is why ongoing research into cancer genetics and the development of targeted therapies is so important in improving treatment outcomes.

Preventing Cancer Through Genetic Understanding

Understanding the genetic basis of cancer risk provides opportunities for prevention. While we cannot change our genetic makeup, there are several strategies available to reduce cancer risk, particularly for individuals who are aware of their genetic predisposition.

Lifestyle Modifications

For those with a family history or genetic predisposition to certain types of cancer, adopting a healthy lifestyle can reduce the risk of developing cancer. Maintaining a healthy weight, exercising regularly, avoiding tobacco use, and limiting alcohol consumption are all key strategies for cancer prevention. A balanced diet rich in fruits, vegetables, and whole grains, as well as minimizing exposure to harmful chemicals and toxins, can further reduce cancer risk.

Targeted Preventive Measures

In addition to lifestyle changes, individuals at higher genetic risk may benefit from targeted preventive measures. For example, individuals with a BRCA mutation may opt for preventive surgeries, as mentioned earlier, or may choose to take medications like tamoxifen or raloxifene, which have been shown to reduce the risk of breast cancer in women at high genetic risk.

For those at risk of colorectal cancer due to inherited conditions like Lynch syndrome, regular colonoscopies starting at an earlier age can help detect precancerous polyps or early-stage cancer, allowing for early intervention.

Gene Therapy and Targeted Treatments

In the future, gene therapy may offer more direct ways to address genetic risk. Scientists are researching ways to repair or replace faulty genes that contribute to cancer risk. While gene therapy is still in its early stages, breakthroughs in this area could revolutionise cancer prevention and treatment, allowing for personalised approaches tailored to an individual’s unique genetic makeup.

Conclusion: The Importance of Genetic Awareness

Genetics plays a crucial role in both the development and prevention of cancer. Understanding the inherited genetic mutations that increase cancer risk can lead to early detection, more effective prevention strategies, and tailored treatments. Genetic testing and counselling can provide invaluable information for individuals and families, empowering them to make informed decisions about their health.

If you have a family history of cancer or are concerned about your genetic risk, it’s essential to speak with a healthcare provider or genetic counsellor. By understanding your genetic predisposition, you can take proactive steps to reduce your risk and improve your overall health.

by Andi Last, Living LFS Secretary & Media Relations – I am part of a group of people with a rare genetic condition called #LiFraumeniSyndrome (LFS). You’ve heard of the infamous BRCA, “the #BreastCancer gene?” LFS is like BRCA on crack. Men with LFS have a 73% lifetime chance of developing #Cancer. For women with LFS, the lifetime chance of developing cancer is nearly 100%. LFS “core” cancer are breast, brain, sarcoma and adrenocortical, but LFS can cause any kind of cancer. Some of us get more than one kind, or even more than one kind at a time. It can also happen at any age, although half of LFS cancer happen before the age of 30. No, unfortunately, I’m not making any of this up. (source: https://www.cancer.net/cancer-types/li-fraumeni-syndrome)

As you can probably imagine, such sobering odds can give those of us with LFS a very different – and sometimes twisted – outlook on life. Part of that twist is that some of us lovingly call ourselves “mutants,” since LFS is caused by a mutation of the TP53 “tumor suppressor” gene.

Recently I asked the members of our private Living LFS online support group, “If you could give one piece of life advice to non-mutants or other “normals” what would it be?” Following are some of the insights from this LFS family of ours – people who currently have cancer, have had cancer, have lost family members to cancer, or have been diagnosed with li-fraumeni-syndrome, a.k.a. “BRCA on crack.”

Don’t Wait, and Don’t Take Time For Granted

Ilonka: When possible I try not to delay doing things that I love to do. Read about Ilonka’s experience at the 2018 LFS International Conference: http://www.livinglfs.org/connecting-the-beautifully-twisted-dana-reed-international-scholarship/

Nina: Stop waiting to do things, or go places, or to do something for you. None of us are guaranteed anything, and it will never be the perfect time to do what you want/need to do. ????

Jonathan: Life is a terminal illness – for everyone. Your life consists of two dates and a dash. Make the most of the dash.

Nadja: To not take time for granted. I’ve just known about my LFS for a few months (and have never had cancer) but I’ve started to feel like “you never know what or when something might happen”. I try to get out and do fun stuff more than before and don’t think as much that “I can do that later”. Better to enjoy life while I can and my body is healthy! ????

Sonja: Find your peace and happiness inside yourself, not outside. Stop thinking: if I stayed healthy, if I became a mum, if I bought the house… In the end, it is not a children, a job, a fiancé, not even your health, that determines how much meaning, peace and happiness you have in your life. It is captured deep inside yourself. All you need, you can find inside yourself. Saying this, I know it is a big challenge to come closer to this source…I am failing on a daily basis, but hey, as long as I breathe there is still a chance to get there!

Prioritize Who You Spend Time With

Ilonka: Although it’s not possible to avoid, I try as much as possible to stay away from people with negative energy.

Emily C: To go ahead and cut the toxic people out because shitty people are just that, shitty. And they’re not going to change. So it’s better to go ahead and cut your ties before something major or life altering happens. There’s nothing worse than thinking you can depend on someone only to find out they simply don’t care, and a lot of times we know beforehand that we can’t depend on them but we expect that maybe they’ll change. We shouldn’t be surprised, but we still are. Relationships of all sorts should never be one sided. And we try to make excuses as to why we can’t cut them out. “But she’s my mother,” “but we’ve been best friends for 20 years,” “but they’re going through some really hard times right now”.

Be Genuinely Supportive: Just Listen

Andi: Many people don’t want to hear about real problems – or aren’t equipped to hear about them. Efforts to be helpful and supportive can do more harm than good. Since diagnosis I understand the phrase, “Everyone you meet is fighting a battle you know nothing about. Be kind. Always.” better than ever. Sometimes, genuine support simply means being forgiving, holding space, and only giving advice if it’s requested.

Julie: I don’t know how to answer this. What is normal? A friend of mine died almost 2 weeks ago from #ColonCancer, she battled it for 2½ years. She wasn’t a mutant, but she’s the one who battled and died. I think she should have been the one to give me advice on life ????

Mandy: My child is not defined by this. She is an amazing girl who is going to do amazing things and I am the lucky one because God chose me to be her Mommy.

Ru’a: Stop talking about cancer (unless you or someone you know is going through it, but too often its used in conversation casually)!!! Stop recommending me shows/movies about it!

www.livinglfs.org/rare-diseases-day-2015-what-people-with-lf...

Samantha: ‘At leasts’ are not helpful. You can at least stuff in your own life, but people telling you at least is not helpful. For example, at least you know, or, at least you are not sick right now (yeah I may have survived the last one, but chances are more is coming, not if, but when) or at least one (or two) of your kids don’t have LFS (like it makes it ok that one or more do? Seriously?) or whatever, nothing takes away from the dark shadow lurking, ready to pounce. This life is real, it can be hard, and the mental load is much more than you can imagine. Please don’t at least us!!!

Greg (President of Living LFS): As someone without LFS, I’ve learned to “listen”. You don’t have to say the right thing, or anything at all, to support someone. Just be there. Read why Greg is a part of Living LFS: http://www.livinglfs.org/about-us/#bod

Have Gratitude, And Love As Much As You Can

Ilonka: The clichés are true, since cancer arrived in my life, I enjoy the little things in life so much more. I don’t take anything for granted, and I love and live more intense, in a good way, most of the times. Oh, and I hardly do material gifts anymore with the people that are most dear to me, I’d rather spend time with them instead.

Andi: The most important thing I have learned from having LFS, and having breast cancer twice, is to have gratitude, every single day. There is so much to be grateful for. Even the small, mundane, basic things. They can be gone so quickly. Appreciate them always. Read Mutant Vs. Monster: Andi Last’s Tale of li-fraumeni-syndrome: http://www.livinglfs.org/mutant-vs-monster-andi-lasts-tale-of-li-fraumeni-syndrome/

Monica: Treasure every moment you have with your family and friends. Don’t take life for granted, everyday is a blessing. Make sure you always say “I love you” to the ones that you love because those little words make a difference. Smile even if you feel like you don’t want to on some days. Monetary things are not as important as you think. It’s the small things, the quality time, that counts in life.

Andrea: Enjoy life, regardless what curve balls may be thrown your way. If you think you have hit rock bottom (ie. Financially) just know the sun is still going shine tomorrow and things are going to get better. Here is a good saying to live by, mutant or non mutant: Yesterday is history, Tomorrow is a mystery, Today is a gift, That’s why they call it the Present.

Jenny F: If there’s anything I have learned, it is to continue to “look up.” I learned that in Toronto first by having to look up to see all the attractions and beauty it has to offer (my first time in a big city, so i had to teach myself to look up). I also realized while I was there that “looking up” refers to many aspects in life and with cancer: keep your head up, look up to God, look up to the clear beautiful blue sky, and last but certainly not all, look up and over and through the clouds, there is always something positive behind them. (Having an emotional day today because of my bone scan, so I had to remind myself of my own advice.)

Fannie: I don’t think people can learn from other people’s experience. This “enjoy every moment thing” happens only once someone tells you you’re gonna die, I think. I don’t think it can be passed on; I can barely apply it myself. I would say just love as much as you can. Love and give and feel and share and touch and breathe and observe and laugh and then love a little more.

Linda H: Love till your heart aches.

Be You, Sparkle and Laugh

Rowena: My advice is just remember you can only be you. Don’t compare your life journeys to anyone else’s, as #1, you have no real idea what theirs is, and #2, yours will never be the same. We are all unique for a reason! ☺

Catherine: Be your TRUE self. There is not enough time or energy to apologize for owning your truth (unless you are an utter ass, then find a hardware store and buy some duct tape). Be and DO YOU! Who cares what makes Mr. or Mrs. Whomever happy. As we know all too well, this body is only borrowed for a bit. Use it for good and have fun!

Brandy: To sparkle even in the darkness! Be your own light and light the fucking world UP!

Also Brandy (heeding her own advice to sparkle!): Don’t half ass anything. Whatever you do, use your full ass.

Jennifer M: Find the humor in every situation. You may have to look hard, and it may be a bit twisted, but find it. And Laugh Hard!
