Clinical Context
Biological effective dose (BED) and equivalent dose in 2 Gy fractions (EQD2) calculations are essential for comparing different fractionation schedules in radiation oncology. The linear-quadratic (LQ) model enables conversion between standard fractionation, hypofractionation, stereotactic body radiation therapy (SBRT), and brachytherapy schedules using tissue-specific α/β ratios.
Brain metastasis prognosis is stratified using the Graded Prognostic Assessment (GPA) and Diagnosis-Specific GPA (DS-GPA) scores, which incorporate age, KPS, number of metastases, and tumor subtype. These scores guide the selection between whole-brain radiotherapy, stereotactic radiosurgery (SRS), and best supportive care.
The normal tissue complication probability (NTCP) models and QUANTEC dose constraints guide radiation treatment planning to minimize toxicity to organs at risk including the lung, heart, esophagus, spinal cord, parotid glands, and rectum.
