Benefits of Personalized Medicine: Tailoring Treatments for Better Outcomes 

Personalized medicine, also known as precision medicine, is an innovative approach tailored for disease prevention and treatment based on people’s genetic makeup, lifestyle, and environment. As you will see in this article, the benefits of personalized medicine (PM) are many.

Firstly, PM can help doctors choose the right dose of the right medicine at the right time for each individual patient. As well as finding the right treatment, personalized medicine can also improve the accuracy of diagnoses, predict the likelihood that someone might develop a condition, and prevent a condition from getting worse.

Additionally, the benefits of personalized medicine also include the ability to target therapy that increases the likelihood of successful treatments, reduce side effects, increase patient engagement, and reduce healthcare costs. It also promotes research and innovation.

In summary, personalized medicine can improve healthcare and reduce healthcare costs, while improving quality of life for patients.

However, experts believe the healthcare industry must overcome many challenges and barriers before personalized medicine can be successfully implemented in healthcare systems. As such, PM is currently only used as the standard procedure in a small number of settings.

Additionally, it is important to realize that PM is not a medical revolution but an evolution.

NOTE: Although I use the term “doctor” for ease of reading, I am referring to all healthcare providers.

What exactly is personalized medicine?

Personalized medicine (PM) uses a patient’s genetic profile (using genomics) to guide decisions regarding the prevention, diagnosis, and treatment of disease. With a patient’s genetic profile, doctors can choose the proper medication or therapy and administer it with the proper dose or regimen.

Simply put, instead of a “one size fits all” approach, doctors can tailor treatments to each patient based on what will likely give them the best possible outcome with the least possible side effects.

This approach has already led to powerful discoveries and FDA-approved therapies specifically tailored to individual characteristics. For instance, knowing the genetic makeup of tumors in a cancer patient can improve the effectiveness of treatment, while sparing him/her from any potential side effects of ineffective treatments.

Excitingly, personalized medicine already impacts various medical specialties and healthcare areas, including cardiology, mental health, and oncology.

The role of genomics in personalized medicine.

Importantly, genomics plays a vital role in personalized medicine, providing insights that allow personalized decisions regarding diagnoses and treatments. Additionally, knowing a person’s genome can allow for personalized predictions about disease risk which can help people choose a prevention plan that is right for them.

What’s the difference between genomics and genetics?

Genetics is the study of genes and their roles in inheritance. For instance, it explains how certain traits or conditions are passed down in the genes from one generation to the next. In healthcare, genetics has typically focused on variations in a single gene to determine the cause of health conditions.

In contrast, genomics is an all-encompassing term that takes into account all the DNA in a person’s (or organism’s) genome – both the genes that code for proteins and the non-coding regions. Genomics looks at how genes are expressed and the interplay between different genes.

How is a genomic sequence analyzed?

Excitingly, new technology can quickly and relatively inexpensively sequence a person’s whole genome, usually using a blood or saliva sample.

What’s the future of genomics?

As mentioned above, barriers in place will impede a rapid expansion of genomics and personalized medicine. Someday, we may have our complete genomes sequenced and placed into our medical records which will help doctors and patients in prevention, diagnosis, and treatment decisions.

The role of proteins in personalized medicine.

Proteins are the workhorses of the cell and most biological functions rely on them. The proteome is the complete set of proteins expressed by an organism, which change over time, depending on physiological conditions.

Proteomics – a key part of personalized medicine – helps scientists and doctors understand health and disease. Modern technology allows scientists to see thousands of proteins simultaneously across dozens – or even hundreds – of samples.

Researchers conduct a protein analysis – using a blood sample – to search for biomarkers (molecules or characteristics in the body) to measure a snapshot of health. Doctors can use this information to estimate a person’s risk of developing a certain disease or the likelihood of a person responding favorably to a treatment.

For instance, measuring C-reactive protein (CRP) – a biomarker for inflammation – can help doctors assess a person’s risk of autoimmune diseases and cardiovascular disease risk. Additionally, proteomics experiments can locate biomarkers for a range of illnesses, including cancer.

The role of “omics” in personalized medicine.

Scientists integrate data from a variety of sources – called multi-omics data. The synthesis of this information, which primarily includes genomics, transcriptomics*, proteomics, and metabolomics**, allows for a comprehensive understanding of a person’s health by analyzing genetic, molecular, and biochemical profiles.

*Transcriptomics is the study of the entire collection of RNA transcripts in a given cell, tissue, or organism at a specific time.

**Metabolomics is the study of small molecules (metabolites) produced during metabolism in biological systems, like cells, tissues, or organisms.

Read below for information regarding some of the benefits of personalized medicine and genomics.

Benefits of personalized medicine: Improved diagnosis and treatment.  

With PM, doctors can make accurate diagnoses based on genetic makeup and identify underlying causes of diseases. This information can help doctors predict which medical treatments will be safe and effective for a patient based on their unique genetic profile. Furthermore, doctors can determine which treatments will not help a patient. This approach can increase the likelihood of success while minimizing the harmful effects of treatment.

Benefits of personalized medicine: Targeted therapies improve effectiveness.

Targeted therapy – a type of personalized medicine – increases the likelihood of successful treatments.

How? Targeted therapy involves the use of drugs that target disease causing molecules (generally, a protein or a gene). In this type of treatment, the drug specifically binds to disease-causing molecules or cells without affecting normal, healthy tissue.

Predictive analysis helps doctors tailor treatments. 

Predictive analytics, a vital part of personalized medicine, leverages vast amounts of data to predict a patient’s disease progression, treatment response, and potential side effects. By combining these datasets with a patient’s unique genetic makeup, medical history, lifestyle factors, and disease profile (e.g., tumor characteristics), predictive models can guide doctors toward tailored treatment plans, thereby maximizing therapeutic effectiveness and minimizing adverse effects.

Benefits of personalized medicine: Biomarkers help with decision making.

Importantly, biomarkers are biological molecules or indicators measured in a patient’s body. The biomarkers provide essential information about the patient’s health status, disease progression, or treatment response.

Biomarkers can take various forms, including proteins, genes, hormones, and even specific cellular structures. As signposts, they provide significant information that help doctors select treatments most likely to work. Additionally, this data can reduce the chance of patients receiving ineffective treatments or potentially harmful treatments.

Biomarker testing may be used for a variety of health conditions, including cancer, heart disease, and Alzheimer’s disease.

Benefits of personalized medicine: Early detection and disease prevention.

Traditionally, medicine reacts to symptoms of conditions already known. However, with PM, doctors have a better indication of diseases that may develop in the future.

With this knowledge, patients can take proactive steps to delay or prevent the onset of disease. Additionally, finding a disease in its early stages can delay or prevent the use of more severe, potentially difficult to tolerate, treatments. Not only can this increase the effectiveness of treatments, but it can also improve the quality of life.

Benefits of personalized medicine: Understanding and predicting a person’s response to medication.

Pharmacogenomics  – a vital component of personalized medicine – studies how genetic variation can impact how a person’s body responds to medication.

Interestingly, a single variation in a gene can impact how medication moves into, through, and out of the body. Additionally, a single variation can alter the time it takes for your body to absorb a drug and how your body metabolizes it.

Excitingly, genomic testing can predict how patients will respond to medications as well as the likelihood of an adverse reaction.

Not only can doctors use this approach in cancer treatments, but doctors can use this information to address inherited genetics that impact the likelihood that a particular person will respond to a medication or develop adverse effects.

Benefits of personalized medicine: Combining real-time health data with genetic profiles.

Digital tools and wearable technologies, such as smartwatches and fitness trackers, allow doctors and patients to monitor vital signs, track medication adherence, and detect early warning signs of potential health complications.

The data gathered in this real-time monitoring, combined with knowledge of a patient’s unique genetic profile, makes it easier for doctors to provide personalized care with highly targeted treatment plans.

Additionally, consistent feedback from these tools encourages patients to take charge of their health.

What role does personalized medicine play in cancer care?

Although there are many health conditions that benefit from personalized medicine, the impact on cancer treatment is tremendous.

With personalized cancer treatment, your genetic profile could play a significant role in determining your best treatment options.

Targeted cancer therapy targets proteins that control how cancer cells grow, divide, and spread. As knowledge grows regarding DNA changes and proteins that drive cancer, scientists can design better treatments to target these proteins. Excitingly, this type of treatment attacks cancer cells without hurting healthy cells.

In contrast, traditional cancer treatment focuses on the location of the cancer. For example, treatments for ovarian cancer are different from treatments for lung cancer. With targeted cancer therapy, your treatment may be based on the genetic change driving your cancer, instead of the location of your cancer.

Interestingly, this approach has fostered the use of medications traditionally only used for one type of cancer to be used for multiple cancers driven by the same genetic mutation.

What are the types of targeted cancer therapy?

Most targeted cancer therapies involve:

• Small-molecule drugs which are small enough to enter cells easily, making them effective for targets inside cells.
• Monoclonal antibodies, also known as therapeutic antibodies, are proteins produced in the lab. These proteins attach to specific targets found on cancer cells. There are several types of monoclonal antibodies. For instance, some mark cancer cells so they will be better seen and destroyed by the immune system. Other monoclonal antibodies directly stop cancer cells from growing or cause them to self-destruct. And others carry toxins to cancer cells. Learn more about monoclonal antibodies.
