Personalized Medicine & Clinical Tools
Personalized Medicine
Definition: Tailoring medical treatment based on individual factors like genetic makeup, tumor behavior, or immune status.
Example: Choosing a drug based on a patient's tumor DNA mutation.
​
Patient-Specific Predictive Modeling
Definition: Using mathematical models and personal patient data (like tumor growth, imaging, and genetics) to predict how they will respond to treatment.
Example: Using a model to figure out the best time for a patient to start therapy.
​
Predictive Modeling
Definition: Using data and math to predict how a disease or treatment will progress.
Example: Estimating the chance that a tumor will come back after treatment.
​
Treatment Response Metrics (e.g., Days Gained)
Definition: Measuring how much a treatment helps slow down disease progression.
Example: “Days Gained” measures how many extra days a treatment delays tumor growth compared to no treatment.
​
MGMT Methylation
Definition: A genetic marker used to help decide the best chemotherapy for glioblastoma patients.
Example: Low MGMT methylation may mean the tumor won’t respond well to certain drugs.
​
Clinical Imaging
Definition: Non-invasive tools like MRI and CT scans to observe and measure tumors.
Example: Measuring tumor size before and after chemotherapy using MRI.
​
Multiparametric Imaging Integration
Definition: Using different types of medical images together to better understand a tumor’s properties.
Example: Combining MRI and PET scans to help calibrate treatment models.
​
Treatment Response Monitoring
Definition: Using imaging and mathematical models to track how tumors shrink or change during treatment.
Example: Monitoring tumor changes using serial MRI scans during radiation therapy.
​
Radiomics
Definition: Analyzing medical images to extract detailed features that help assess tumor characteristics.
Example: Analyzing the texture of an MRI scan to determine how aggressive a tumor is.
​
Radiogenomics
Definition: Connecting features from medical images with genetic data to understand a tumor better.
Example: Using CT scan features to predict a genetic mutation in the tumor using machine learning.
​
Machine Learning in Radiogenomics
Definition: Using algorithms to learn from both medical images and genetic data to make predictions.
Example: Using machine learning to predict a tumor’s HPV status from its CT scan features.
​
Big Data
Definition: Large sets of data from clinical, genetic, and imaging sources that help doctors make better treatment decisions.
Example: Using patient data, genetic information, and imaging to develop personalized treatment plans.
​
Bayesian Inference
Definition: A method of using existing knowledge and new data to estimate uncertainties in predictions.
Example: Using Bayesian methods to figure out how certain we are about how much a treatment delays tumor growth.
​
Random Forests
Definition: A machine learning technique that builds multiple decision trees and combines them to make predictions.
Example: Using random forests to predict tumor malignancy by combining decisions from several trees based on tumor features like size and texture.
