    Area of Science:

    • Oncology
    • Radiotherapy
    • Biostatistics

    Background:

    • Prognostic indexes like RPA, GPA, and WBRT30 aid treatment selection for brain metastases.
    • Current indexes are complex, limiting routine clinical use.
    • A practical spreadsheet tool was developed to simplify index calculation.

    Purpose of the Study:

    • To develop and evaluate a spreadsheet tool for calculating prognostic indexes (RPA, GPA, WBRT30).
    • To assess the tool's utility in clinical decision-making for palliative radiotherapy in brain metastases.
    • To perform a retrospective survival analysis based on calculated indexes.

    Main Methods:

    • A spreadsheet platform was created for automatic calculation of RPA, GPA, and WBRT30 indexes.
    • 121 patients undergoing palliative radiotherapy for brain metastases were analyzed.
    • Calculated survival parameters were compared with estimated ones, and radiotherapy techniques were evaluated.

    Main Results:

    • Median overall survival was 3.13 months.
    • Significant differences in overall survival were observed across subgroups for all three scoring systems.
    • The tool facilitated the analysis of patient survival based on prognostic indexes.

    Conclusions:

    • Routine calculation of prognostic indexes is valuable for guiding radiotherapy decisions in brain metastases.
    • Widely available spreadsheet tools significantly simplify the calculation and application of these indexes.
    • The developed tool enhances the practical utility of prognostic indexes in clinical settings.
