Functional information guided adaptive radiation therapy.
1Hillman Cancer Center, Radiation Oncology, University of Pittsburgh Medical Center, Williamsport, PA, United States.
Functional information enables personalized cancer therapy by mathematically linking tumor biomarkers and treatment response models. This adaptive approach allows for individualized adjustments in radiation dose, chemotherapy, and immunotherapy for better patient outcomes.
Area of Science:
- Biomedical Engineering
- Computational Biology
- Oncology
Background:
- Cancer therapies require adaptation for individual patients.
- Tumor biomarkers offer insights into treatment response.
Purpose of the Study:
- Introduce functional information as a mechanism for adaptive cancer therapy.
- Demonstrate a method to uniquely adapt therapies based on tumor biomarkers.
Main Methods:
- Developed a tumor volume biomarker model using a reduction rate coefficient.
- Adapted a radiotherapy model using functional information to link biomarker and bioresponse data.
- Quantified biomarker and bioresponse data in information units to create an analytic conduit.
Main Results:
- Presented an information-guided process for individualized dose adaptations.
- Utilized clinical data to demonstrate the methodology for adaptive cancer therapy research.
- Showcased a flowchart and tabular data for the information-guided process.
Conclusions:
- Functional information mathematically connects disparate bioresponse and biomarker data sets.
- This approach is extensible across multiple research fields.
- Functional information facilitates adaptive cancer therapy by integrating immunotherapy, chemotherapy, and radiotherapy for individualized treatment plans.
