Introduction to Personalized Medicine
Personalized medicine (PM) is a new way to change healthcare. It offers treatments that fit each person’s unique genetic and molecular makeup2. This method aims to give the right treatment to the right person at the right time2. It helps doctors make better choices and patients get care that really works for them.
Definition and Concept of Personalized Medicine
At its heart, personalized medicine puts patients first. It uses new tech in genomics and data to sort people based on their genes and molecules3. This way, doctors can find the best treatments for each person, leading to better health and fewer side effects3.
Tailoring Treatment to Individual Needs
Personalized medicine’s strength is in customizing care for each person. Doctors can pick the best treatments and dosages based on a patient’s genes and health3. This method boosts the chance of good results and cuts down on bad side effects, making care better and more satisfying3.
Knowing a person’s genes and using new tech in data and biology opens up a new chapter in health care4. It lets people find out their health risks and take steps to stay healthy4.
“The 21st century vision of personalized medicine is to provide the right drug, with the right dose at the right time to the right patient.”
The Role of Genomics in Personalized Treatment
Personalized medicine uses advanced diagnostic tools to find the best treatments for patients. Genetic profiling and molecular diagnostics are key in this field. They help identify genetic markers and understand disease mechanisms5.
This knowledge lets doctors group patients by how they’ll react to treatments. This approach can greatly improve patient care.
Genetic Profiling and Molecular Diagnostics
Genomics is changing healthcare, especially for rare diseases and cancer5. Whole genome sequencing (WGS) can spot millions of genetic differences in each genome5. But, it’s expensive and hard to understand5.
Sequencing DNA from tumors helps find cancer drivers. This guides doctors in choosing treatments5. Genomic tests also affect family members and future generations, making careful categorization crucial5.
| Key Milestone | Year |
|---|---|
| Human Genome Project (HGP) launched | 19906 |
| First draft of HGP published | 20016 |
| Final version of HGP published | 20036 |
| Herceptin approved as first “official” companion molecular diagnostics (CMDx) test | 19986 |
The Human Genome Project mapped over 3 billion DNA base pairs over 13 years5. In the UK, there are about 6,000 rare diseases, affecting 3.5 million people5. About 80% of these diseases have genetic causes5.
“Precision medicine aims to provide the right treatments to the right patients at the right time.”
While precision medicine is still a goal, recent data has helped it grow. Big data analysis, like deep learning, is key in healthcare6. But, using these tools in real-world medicine is still limited6.
Pharmacogenomics is a big part of personalized medicine. For example, the TPMT gene helps decide how much of certain drugs to give to leukemia patients7. People with the TPMT*3A variant need much less of these drugs to avoid serious side effects7.
A study in healthy Europeans found that genetic testing for TPMT is very accurate7. It’s considered a valuable tool in medicine756.
Targeted Therapies and Precision Medicine
Precision medicine has opened up new chances for drug makers to create molecular-targeted therapeutics. This new way also means using and repurposing drugs and combining them8. It changes how we diagnose and treat, making patients more involved in their care8.
Molecular targeted therapies include drugs like Herceptin for breast cancer. They also treat rheumatoid arthritis and inflammatory bowel disease9. Precision medicine in cancer tailors treatments to a patient’s genes and lifestyle9.
Precision medicine is a better option than old treatments like chemotherapy9. Cancer is very different, with many types and subtypes9. Doctors use it to find the right treatments by looking at tumor genetics9.
| Concept | Proportion of Participants with Relative Who Had Cancer |
|---|---|
| Personalized Medicine | 37 out of 48 in the English foreign language group to 48 out of 62 in the psychology group8 |
| Targeted Therapies | 42 out of 57 in the English foreign language group to 44 out of 63 in the medicine group8 |
Precision medicine helps find the right treatments for patients, improving cancer care9. Doctors use it when standard treatments don’t work9. It also helps predict cancer risk by looking at inherited genes9.
“Precision medicine immunotherapies include targeted therapies like CAR T cell therapy, cancer vaccines, and immune checkpoint inhibitors like pembrolizumab for cancers that evade the immune system.”
The growth of targeted therapies and precision medicine has changed how we treat diseases, especially cancer.
Personalized Treatment Options for Specific Conditions
Cancer and Targeted Therapies
In cancer treatment, understanding a patient’s genes and epigenetics is key. This knowledge helps use targeted therapies like Herceptin10. It ensures the right treatment for those with HER2 levels and resistance to Herceptin10.
The FDA has approved over 160 biomarkers for guiding drug use10. Also, 33.5% of biomarkers in oncology have FDA approval10. For example, the MammaPrint™ test for breast cancer was approved in 200710.
Cardiovascular Diseases and Pharmacogenomics
In heart diseases, pharmacogenomics is vital. It tailors treatments to a patient’s genetic makeup. This approach reduces side effects and boosts drug effectiveness10.
Tools like Geno2pheno predict HIV drug resistance based on viral genotype10. The S3 score also predicts outcomes in certain cancers10.
| Diagnostic Test | Description |
|---|---|
| Clinical Genetic Testing | Offers a comprehensive range of tests for analyzing hematologic disorders, central nervous system tumors, and solid and soft tissue tumors which aid in diagnosis and treatment planning11. |
| 22q11.2 Deletion/Duplication Analysis | This test by the Department of Pathology and Laboratory Medicine and the Center for Personalized Medicine is indicated for individuals with disorders associated with copy number alterations of the 22q11.2 region, such as DiGeorge/Velocardiofacial syndrome, 22q11.2 duplication syndrome, and Cat Eye syndrome11. |
| Chromosomal Microarray Analysis | Recommended as the first tier diagnostic test for pediatric patients with certain conditions by the American College of Medical Genetics, the American Academy of Neurology, and the American Academy of Pediatrics11. |
| Clinical Exome Sequencing | A highly complex test aiming to identify genetic changes among the ~20,000 genes that encode proteins crucial to bodily processes, particularly efficient when analyzing a patient’s sample together with those of both parents11. |
“Personalized treatment options for cancer and cardiovascular diseases have the potential to significantly improve patient outcomes by tailoring therapies to individual genetic profiles and molecular characteristics.”
Integrating personalized treatments into healthcare is a big step forward. It leads to better care for patients with complex conditions10. By using targeted therapies and advanced diagnostics, doctors can make treatment plans more effective10.
Patient-Centric Care and Individualized Approaches
Personalized medicine (PM) focuses on each patient’s unique situation to find the best treatment. This approach respects the patient’s preferences, values, and needs12. For example, in prostate cancer, patients can choose between immediate treatment or waiting for signs of disease progression12.
This empowers patients to be involved in their care. It ensures their situation and preferences guide treatment choices.
Effective care needs a team effort between healthcare providers, patients, and families13. This teamwork respects the patient’s wishes, leading to better health outcomes and a kinder healthcare system13. Patients with chronic conditions especially benefit from this approach, needing a tailored wellness plan13.
Patient-centered care looks at all aspects of care, including physical, emotional, and social13. It involves creating personalized wellness plans and ensuring care flows smoothly13. This approach requires open conversations about treatment options, considering the patient’s background and values13.
When patients are involved in their care, they are more likely to follow their wellness plans and prevent health issues13.
The move towards patient-centric care is driven by initiatives like the UK’s Integrated Personal Commissioning (IPC) scheme14. It lets people with complex needs buy support with their own budget14. The UK Supreme Court’s ruling also emphasizes the importance of patients understanding their treatment choices14.
While progress is slow, the value of patient-centered care is clear12. By putting patients at the center, healthcare can offer care that fits each person’s unique needs13.
“Patient-centered care establishes a partnership among practitioners, patients, and their families…to ensure that decisions respect patients’ wants, needs, and preferences.”12
| Principles of Patient-Centered Care | Examples |
|---|---|
| Respect for patient values | Considering cultural background, personal values, and socioeconomic conditions |
| Clear communication | Providing information and involving patients in shared decision-making |
| Emotional support | Compassionate, active listening and ongoing patient communication |
| Family involvement | Collaborating with patients and their families to deliver personalized care |
| Continuity of care | Seamless care coordination and integration of physical, emotional, and social aspects |
| Fast access to care | Providing timely and convenient access to healthcare services |

This leads to better health and saves money for the healthcare system18.
Improved Outcomes and Reduced Side Effects
PM uses genetic tests and targeted therapies to find the best treatments for each patient. This approach can cut down on bad reactions to drugs. It’s known that up to 50% of patients don’t get better with the first drug they try, showing how important personalized care is18.
PM also targets specific genetic markers, like the HER2 protein in some breast cancers. This makes treatments more precise and effective18.
Cost-Effectiveness and Healthcare Savings
Personalized treatments can save a lot of money for healthcare. They prevent unnecessary hospital stays and bad drug reactions, which cause about 5.3% of hospital admissions18. This can lower long-term healthcare costs.
Patients who know their genetic makeup are more likely to stick to their treatment, with over 86% adherence after two years. This is compared to 38% before testing18. This shows how PM can lead to better health and save money.
Using existing drugs in new ways and stopping disease progression through personalized care also saves money. For example, the drug Iressa® (gefitinib) helped about 10% of patients with specific genetic mutations, even though it didn’t help everyone18. This shows how PM can give the right care to the right patients, improving health and reducing healthcare costs.
“Precision medicine has the potential to prevent unnecessary hospitalizations and care, reducing long-term costs.”18
