What is precision medicine
Imagine that you and another person are diagnosed with the same disease.
And yet you experience the illness in different ways, from how your diseases progress to which treatments are most effective.
TAKEAWAY
Precision medicine provides insight into how your individual biomarkersA biomarker is a sign of disease or abnormal function that can be measured in your blood, tissue, or bodily fluid. In cancer, biomarkers are often used to help choose the best treatment for you. These biomarkers can be proteins, genes, or gene mutations. Biomarkers are often referred to by a 3 or 4 letter abbreviation. Examples of biomarkers are HER2 in breast cancer or EGFR in lung cancer (Cancer Support Community, Precision Medicine Plain Language Lexicon). can be matched with the right treatment.

Check out this video from the Leukemia & Lymphoma Society to learn about what precision medicine means for cancer patients.
Including the diseases you may develop, the symptoms you may experience, and the ways in which your body might respond to certain treatments.
Instead of a one-size-fits-all approach to health care, precision medicine a form of medicine that uses information about a person’s own genes or proteins to prevent, diagnose, or treat disease. In cancer, precision medicine uses specific information about a person’s tumor to help make a diagnosis, plan treatment, find out how well treatment is working, or make a prognosis (National Cancer Institute, Dictionary of Cancer Terms). takes into account these differences between individuals to find the best possible therapies.

When there’s a suspicion of a cancer diagnosis, there might be the recommendation to undergo special testing
Biomarker testing
Biomarker testing can help patients and their healthcare team get information on your specific cancer to help make informed decisions for optimal treatment.
Biomarker testing can be done to look for mutations in a cancer (called somatic mutations). Somatic mutationsTwo kinds of mutations can be found in cancer cells — mutations you inherit and mutations you acquire during your lifetime (called somatic mutations). Inherited mutations are found in all your cells. Somatic/quaired mutations may only be found in the cancer’s cells. Somatic/acquired mutations happen as you get older and are the result of the wear and tear of life. These mutations were not inherited and cannot be passed on to children. Mutations in the cancer can affect how the cancer grows and spreads. These mutations can also define the cancer's subtype. Mutations in the cancer can be a type of biomarker. A biopsy sample or liquid biopsy is needed to test for mutations in the cancer (Cancer Support Community, Precision Medicine Plain Language Lexicon). cause most cancers and can’t be passed on to family members.
While biomarker testing does not always contribute to a diagnosisThe process of identifying a disease, condition, or injury from its signs and symptoms. A health history, physical exam, and tests, such as blood tests, imaging tests, and biopsies, may be used to help make a diagnosis. (National Cancer Institute, Dictionary of Cancer Terms). , it can provide crucial information about the tumor type.
Genetic testing the process of analyzing cells or tissue to look for changes in genes, chromosomes, or proteins that may be a sign of a disease or condition, such as cancer. These changes may also be a sign that a person has an increased risk of developing a specific disease or condition. Genetic testing may be done on tumor tissue to help diagnose cancer, plan treatment, or find out how well treatment is working (National Cancer Institute, Dictionary of Cancer Terms).
Also genetic testing can support patients and the healthcare team in getting the right information to make informed decisions.
Different from biomarker testing, genetic testing looks for mutations in your genes that can cause/increase the chances for a disease.
Identification of a somatic mutation
A somatic mutation is a variation in your cancer’s DNA. Because these mutations are cancer specific, you cannot pass them on to family members.
Identification of an inherited mutation(also called germline mutations) Two kinds of mutations can be found in cancer cells — mutations you inherit and mutations you acquire during your lifetime (called somatic mutations). Inherited mutations are found in all your cells. They are passed on from parents to offspring (Cancer Support Community, Precision Medicine Plain Language Lexicon). or cancer risk
An inherited mutation is a variation in your DNA. It is inherited from your parents and can be passed on to your children.
However, there are some limitations to access that patients, healthcare professionals, and regulators should be aware of when considering precision medicine as a solution:
Precision medicine is a growing field but is not yet widely available. Patients may not have access to targeted therapies, or there might not yet be a targeted treatment available for specific mutations.
FT3 partners are working on mapping precision medicine access information at global and country level.
Check out the first cards hereEven if you receive targeted therapy A type of treatment that uses drugs or other substances to identify and attack specific types of cancer cells with less harm to normal cells. Some targeted therapies block the action of certain enzymes, proteins, or other molecules involved in the growth and spread of cancer cells. Other types of targeted therapies help the immune system kill cancer cells or deliver toxic substances directly to cancer cells and kill them. Targeted therapy may have fewer side effects than other types of cancer treatment. Most targeted therapies are either small molecule drugs or monoclonal antibodies (National Cancer Institute, Dictionary of Cancer Terms). , you might build resistance to the treatment. In this case, you may need further testing to find new therapies.

Check hereBiomarker tests (also referred to as Comprehensive biomarker testing, Gene-based cancer testing, Genetic testing of the cancer, Cancer marker testing, Next generation sequencing, Genomic profiling, Mutation biomarker testing, Genomic testing, Molecular profiling, Tumor marker testing, Mutation testing, Molecular testing): Biomarker testing helps your doctor match the right drugs to the specific subtype of cancer you have. In biomarker testing, a sample of your cancer is collected from your blood, bodily fluids, or tissue taken during surgery or biopsy. Your sample is sent to a lab. The test looks for biomarkers in your cancer sample. The test results can be used to help guide your treatment options. Biomarkers tell your doctor about the subtype of the cancer in your body (Cancer Support Community, Precision Medicine Plain Language Lexicon). are not available at all medical centers. The required testing procedures might delay your treatment. But the results could be key in determining the most appropriate therapy.
Although targeted therapy is not yet widely available, results of testing may open the door to participation in clinical trials. A type of research study that tests how well new medical approaches work in people (National Cancer Institute, Dictionary of Cancer Terms).

It’s time for precision medicine to deliver the promise to patients. However, there are existing barriers in the healthcare systems that need to be addressed in order to accomplish that.

WHY
The story of precision medicine has not been told as such, in the context of wider medical progress, with a history and a future. Precision medicine is mainly explained in a very technical way, focused on specific health technologies.
There is limited storytelling about precision medicine as an overall topic in lay language, including the patient experience and patient stories.
GOAL
Support readiness and cultural change by equiping Precision Medicine Champions with information and resources that will establish among stakeholders a common understanding of the value of Precision Medicine. This is done through a dynamic and engaging narrative describing what precision medicine is, its value for patients that can benefit from it, and its progress and potential for the future.
