Artificial intelligence in precision medicine is a revolutionary new approach advancing health and wellness, knowledge, and health care delivery to maximize the quality of life for all over a lifetime. The main concept of precision medicine is providing health care which is individually tailored on the basis of a person’s genes, lifestyle and environment. With the advances in genetics, artificial intelligence and the growing availability of health data, present an opportunity to make precise personalized patient care a clinical reality.
It is like cricket. No two cricket ball deliveries, players, — or patients — are exactly alike. No two games or diseases are exactly the same. To win the game every ball, every delivery needs unique strategy. Precision medicine is like that. No two diseases are same, so the treatments will be different and unique.
AI with precision medicine is a part of artificial intelligence in health care. It brings together innovations in genomics, metabolomics, mobile health, biomedical data sciences, imaging, social engagement and networking, communication, and environmental sciences to make diagnostics, therapeutics, and prevention more individualized, proactive, predictive, and precise.
Precision medicine often involves the application of panomic analysis and systems biology to analyze the cause of an individual patient’s disease at the molecular level and then to utilize targeted treatments (possibly in combination) to address that individual patient’s disease process. Here Panomicsrefers to the range of molecular biology technologies including genomics, proteomics, metabolomics, transcriptomics, and so forth, or the integration of their combined use. Systems biology approaches are often based upon the use of panomic analysis data.
The National Research Council explains it as: “Precision Medicine refers to the tailoring of medical treatment to the individual characteristics of each patient. It does not literally mean the creation of drugs or medical devices that are unique to a patient, but rather the ability to classify individuals into sub-populations that differ in their susceptibility to a particular disease, in the biology or prognosis of those diseases they may develop, or in their response to a specific treatment.
Preventive or therapeutic interventions can then be concentrated on those who will benefit, sparing expense and side effects for those who will not. Although the term ‘personalized medicine’ is also used to convey this meaning, that term is sometimes misinterpreted as implying that unique treatments can be designed for each individual.”[1]
Artificial intelligence in precision medicine combines genetic, proteomic, structural, and computational methods to proceed from patient-based systems data, such as genome-wide association studies, to functional complexes, to pathways, and ultimately to predictive networks.
Availability of Large Data for Machine Learning
Large data sets are now available through international collaborative projects, such as the 1000 Genomes Project, the 100,000 Genomes Project, ENCODE, the Roadmap Epigenomics Project and the US National Institutes of Health’s 4D Nucleome Initiative. These large data offer an opportunity for machine learning to have a significant impact on biology and precision medicine.
Artificial Intelligence for Genome Sequencing
Genes are the building blocks of life. When a gene is expressed, it is first transcribed into an RNA sequence, and the RNA is then translated into a protein, a sequence of amino acids. Normally, for small scale, biologists measure the protein-production rate directly, but that is very difficult and impractical on a large scale. Alternatively, machine learning algorithms process can measure gene-expression levels more efficiently.
The genotype is the set of genes in our DNA which is responsible for a particular trait. The phenotype is the physical expression, or characteristics, of that trait. A clinical phenotype is the presentation of a disease in a given individual. A clinical phenotype may be result from complex, nonlinear, and often stochastic interactions among various factors that contribute to the phenotype. Even a single gene disorder can cause a disease. Common diseases such as coronary artery disease and hypertension are caused, at the genetic level, by a combination of common and rare variants. Predicting clinical phenotype requires knowledge of the genetic diversity of the humans, etiological complexity of the clinical phenotype, and phenotypic variability of the diseases and artificial intelligence has a crucial role to play.
Artificial Intelligence for Genomics sequencing help medical professionals to interpret how genetic variation affects metabolism, DNA repair, and cell growth. Machine learning algorithms are designed based on patterns identified in large genetic data sets. Generally, machine learning methods generally have one of two goals: prediction or interpretation. Gene-expression microarrays, commonly called “gene chips”, make it possible to measure the rate at which a cell or tissue is expressing itself in translating into a DNA-to-RNA to protein. Artificial intelligence gives the ability to measure at once the transcription of all the genes in an organism. For this, the amount of data that biologists need to examine is overwhelming. Finding some combination of genes whose expression levels can distinguish the groups of patients is a daunting task for a human, but a relatively natural one for a machine-learning algorithm.
How AI Enhances Precision Medicine
1. Genomic Data Analysis
AI plays a critical role in analyzing genetic data to identify mutations or variations linked to diseases. Machine learning algorithms can sift through massive genomic datasets to pinpoint patterns that indicate a patient’s risk of conditions like cancer or heart disease. This enables:
- Early detection of diseases based on genetic predispositions.
- Development of personalized prevention or treatment strategies.
2. Drug Discovery and Development
AI accelerates the traditionally slow and expensive process of drug discovery and development by:
- Analyzing large datasets of chemical compounds and their interactions with biological systems.
- Predicting potential drug candidates for specific diseases or patient groups. This leads to faster development of targeted therapies, particularly for rare diseases or individualized needs, reducing the time and cost of bringing new drugs to market.
3. Medical Imaging and Diagnostics
AI enhances diagnostic accuracy by analyzing medical images, such as MRIs, CT scans, or mammograms. For example:
- Deep learning models can detect abnormalities like tumors or fractures that might be missed by human eyes.
- AI tools improve early diagnosis, such as identifying breast cancer at its earliest stages. This results in earlier interventions and better treatment outcomes.
4. Predictive Analytics for Patient Outcomes
AI uses data from electronic health records (EHRs), lab results, and other sources to:
- Predict a patient’s risk of developing specific conditions.
- Forecast how they might respond to a particular treatment or their likelihood of complications, such as hospital readmission. This allows healthcare providers to proactively adjust treatment plans, improving patient care and reducing costs.
5. Personalized Treatment Plans
By integrating data from genomics, clinical history, and lifestyle factors, AI recommends tailored treatment options. For instance:
- In oncology, AI can analyze tumor genetics to suggest the most effective chemotherapy regimen for an individual patient. This minimizes trial-and-error, reduces side effects, and enhances treatment success.
6. Wearable Devices and Real-Time Monitoring
AI-powered wearable devices and remote monitoring tools track vital signs and detect anomalies in real time. Examples include:
- Smartwatches predicting heart attacks or strokes by analyzing heart rate data.
- Continuous monitoring of chronic conditions like diabetes. This enables timely interventions, improves quality of life, and reduces the need for frequent hospital visits.
Compassionate AI with Precision Medicine
The integration of compassionate AI with precision medicine can lead to significant advancements in patient care. Here are some key areas where this synergy can be beneficial:
Enhanced Patient Engagement
AI-driven tools can facilitate better communication between patients and healthcare providers. For instance, virtual health assistants can provide personalized information and support, helping patients understand their conditions and treatment options. By fostering a more engaging and supportive environment, patients are more likely to adhere to their treatment plans and actively participate in their healthcare journey.
Improved Decision-Making
AI algorithms can analyze vast amounts of data to identify patterns and predict outcomes, aiding healthcare providers in making informed decisions. When combined with compassionate AI, these tools can also take into account the emotional and psychological aspects of patient care, ensuring that treatment recommendations align with patients’ values and preferences.
Challenges and Limitations
While AI offers immense potential, several hurdles must be addressed to fully realize its benefits in precision medicine:
1. Data Quality and Quantity
- AI models require large, high-quality datasets to function effectively.
- In precision medicine, obtaining such data is challenging due to privacy regulations, data silos, and the inherent complexity of biological systems.
2. Interpretability
- Many AI models, particularly deep learning systems, are “black boxes,” meaning their decision-making processes are not fully transparent.
- In medicine, understanding why a model makes a specific prediction is crucial for clinician trust and patient safety, making interpretability a significant concern.
3. Bias and Fairness
- If training data is biased (e.g., lacks diversity across populations), AI models can perpetuate or amplify these biases.
- This could lead to unequal healthcare outcomes, disproportionately affecting certain patient groups.
4. Integration into Clinical Practice
- Even with effective AI tools, integrating them into existing healthcare systems and workflows is complex.
- Technical, regulatory, and cultural barriers must be overcome to ensure widespread adoption.
