Personalized medicine considers the uniqueness of each cancer patient’s tumor, and uses the description of mutated genes to define each patient’s unique set of therapeutic targets. In this approach, molecular profiling of the tumor, or tumor profiling, is the first step in the process.

How biomarkers are helpful for personalized Onco Therapy?
Predictive (diagnostic) biomarkers are helpful in matching targeted therapies with patients and in preventing toxicity of standard (systemic) therapies. Prognostic biomarkers identify somatic germ line mutations, changes in DNA methylation, elevated levels of microRNA (miRNA) and circulating tumor cells (CTC) in blood.
What significance does PM have on personalizing cancer treatments for cancer patients?
It's sometimes called personalized medicine or personalized care. Precision medicine looks at how a specific gene change (gene mutation) might affect a person's risk of getting a certain cancer or, if they already have cancer, how their genes (or genes in their cancer cells) might affect treatment.
What is tumor genetic profiling?
Biomarker testing (also called tumor testing, tumor profiling, or tumor genetic testing) finds changes in your cancer that could help you and your doctor choose your cancer treatment.
What types of information might be used in the development of personalized cancer therapies to respond to an individual patient's tumor?
Personalized cancer medicine comes from studies of human genes and the genes in different cancers. These studies have helped researchers design more effective treatments. They have also used genetic information to develop tests for cancer and ways to prevent it.
How does precision targeted therapy work?
Targeted therapy is a type of cancer treatment that targets proteins that control how cancer cells grow, divide, and spread. It is the foundation of precision medicine. As researchers learn more about the DNA changes and proteins that drive cancer, they are better able to design treatments that target these proteins.
What is the importance of personalized medicine?
Personalized medicine, because it is based on each patient's unique genetic makeup, is beginning to overcome the limitations of traditional medicine. Increasingly it is allowing health care providers to: shift the emphasis in medicine from reaction to prevention. predict susceptibility to disease.
What does genomic profiling mean?
A laboratory method that is used to learn about all the genes in a person or in a specific cell type, and the way those genes interact with each other and with the environment.
What is molecular profiling used for?
A laboratory method that uses a sample of tissue, blood, or other body fluid to check for certain genes, proteins, or other molecules that may be a sign of a disease or condition, such as cancer.
Is molecular profiling the same as genetic testing?
Molecular profiling—or “tumor genomic profiling”—is a form of testing that classifies tumors based on this genetic make-up to help diagnose and treat cancer. Using a blood test or biopsy, this testing examines the DNA of cancer cells, looking for genetic mutations that have been acquired by these cells.
How can genetic testing help with cancer treatment?
Genetic testing helps estimate your chance of developing cancer in your lifetime. It does this by searching for specific changes in your genes, chromosomes, or proteins. These changes are called mutations. Genetic tests are available for some types of cancer.
Why are biomarkers important in cancer?
When a biomarker is identified in a cancer through molecular or genetic testing, it tells the physician what makes the cancer grow and thrive, and that information allows physicians to decide what may be the most effective treatment for the patient.
How do cancer genomics aid the diagnosis and treatment choices for the disease?
In practice, genomics is important because: Genomic analysis of the DNA changes present in cancer cells – known as somatic variants / mutations, or acquired variants / mutations – can be helpful when determining which treatments are likely to be effective.
What is tumor profiling?
Tumor profiling companies use a variety of techniques to analyze the biopsy sample, and return information about the genes altered in the cancer cells. However, some companies only focus on specific cancer types. When selecting a tumor profiling company, it is important to know which types of cancer each company focuses on. Several examples are listed below:
What is the first step in a cancer biopsy?
The first step in the process is a biopsy, in which a sample of tissue, blood, or urine is taken from the patient’s body for analysis. It is important to consider the types of biopsy available, although for some cancer patients, the choice of biopsy maybe be limited to one option. For patients with hematological cancers and bone marrow cancers, a liquid biopsy may be the only viable choice. Conversely, if a patient has recently had surgery to remove some or all of their tumor, it may be best to request that a sample of the tumor be used for tumor profiling rather than performing a second procedure.
Is cancer unique?
Every patient’s cancer is unique. However, the vast majority of cancer patients are still treated as if cancers can be grouped together by the organ of origin (e.g., colon cancer, breast cancer) rather than by looking at each cancer on an individual basis. Personalized medicine considers the uniqueness of each cancer patient’s tumor, and uses the description of mutated genes to define each patient’s unique set of therapeutic targets. In this approach, molecular profiling of the tumor, or tumor profiling, is the first step in the process.
How does molecular profiling help with cancer?
As an instrument of “personalized medicine,” molecular profiling can help your doctor individualize your disease management plan by tailoring your treatment to the specific biomarkers found in your cancer.
What is molecular profiling?
Molecular profiling, a service also known as tumor profiling, can help you manage your rare or aggressive disease by giving your doctor very specific information about your tumor’s genetic composition and other biomarkers that constitute your cancer’s molecular “signature.”.
What is standard of care for cancer?
The phrase “standard of care” or “standard treatment” is used to describe the most common and effective treatment option for your cancer based on several characteristics such as the body part where your cancer first appeared (e.g. the breast, colon, or lung), the location of any metastases, and its stage of progression.
Is molecular profiling a first line treatment?
If you are a patient with a rare or aggressive cancer, you may find that standard or first-line treatment options aren’t working for you. Or perhaps there’s no standard treatment available for your particular cancer in the first place.
Does molecular profiling work for everyone?
While many patients do find effective treatments through the standard of care, it doesn’t work for everybody. This is especially true for patients with rare and/or aggressive cancers that are difficult to treat. For those patients, a more personalized approach, using tools like molecular profiling, is needed to guide therapy.
