    Summary

    Radiation therapy improved disease-free survival for many adult brain tumors after subtotal resection. New high-dose radiotherapy for malignant gliomas shows promise for better survival rates.

    Area of Science:

    • Neuro-oncology
    • Radiation Oncology
    • Neurosurgery

    Background:

    • Radiation therapy is a cornerstone in treating adult brain tumors.
    • Outcomes vary significantly across different brain tumor histologies.
    • Advances in radiation techniques are crucial for improving patient survival.

    Purpose of the Study:

    • To review radiation therapy outcomes for adult brain tumors over 25 years.
    • To evaluate the impact of subtotal resection followed by irradiation.
    • To explore novel therapeutic strategies for malignant gliomas.

    Main Methods:

    • Retrospective analysis of radiation therapy results for adult brain tumors.
    • Inclusion of astrocytomas, ependymomas, pineal/suprasellar tumors, meningiomas, and malignant gliomas.
    • Discussion of multimodality therapies and a new high-dose radiotherapy program.

    Main Results:

    • Subtotal resection followed by irradiation improved disease-free survival for most tumor types.
    • Malignant gliomas showed a lack of survival improvement with standard irradiation.
    • A new high-dose radiotherapy program using iodine-125 sources was initiated.

    Conclusions:

    • Irradiation following subtotal resection is beneficial for several adult brain tumors.
    • Novel approaches are needed to improve outcomes for malignant gliomas.
    • High-dose radiotherapy with iodine-125 may enhance survival for central nervous system tumors.
