Prediction of Outcomes of Brain Irradiation in Correlation with Molecular Subtypes in Patients with Metastatic Breast Cancer

Key Points

The central aim is to identify prognostic factors that impact survival in breast cancer patients with brain metastases and to propose a scoring system for treatment decisions.
Analysis of molecular subtypes and clinical characteristics in patients with metastatic breast cancer.
Identification of key factors influencing survival outcomes.
Development of a scoring system to aid in radiotherapy decision-making.
HER2-positive and triple-negative subtypes have the poorest survival rates.
The proposed scoring system helps guide radiotherapy decisions based on patient-specific factors.
Further validation is necessary to confirm the scoring system's accuracy and utility.

Abstract

This study identifies key prognostic factors influencing survival in breast cancer patients with BM and proposes a scoring system to guide radiotherapy decisions. Molecular subtypes, metastatic burden, and clinical characteristics significantly affect outcomes, with HER2-positive and triple-negative subtypes showing the poorest survival. The system provides a structured approach for treatment selection, though further validation is needed to ensure its accuracy and clinical utility in personalized radiotherapy planning.
