Reoperation for glioblastoma.

B Young, E H Oldfield, W R Markesbery

    Journal of Neurosurgery
    |December 1, 1981
    PubMed
    Summary

    Second surgeries for glioblastoma offer limited survival benefits. Patients with a Karnofsky rating (KR) of at least 60 before reoperation have better outcomes, suggesting careful patient selection is crucial for tumor removal.

    Area of Science:

    • Neurosurgery
    • Oncology
    • Clinical Neurology

    Background:

    • Supratentorial glioblastoma multiforme and anaplastic astrocytoma are aggressive brain tumors.
    • Reoperation for recurrent or residual tumors is a treatment option, but its efficacy requires further investigation.

    Purpose of the Study:

    • To analyze the outcomes of a second operation for tumor removal in adult patients with supratentorial glioblastoma multiforme or anaplastic astrocytoma.
    • To identify prognostic factors influencing survival after reoperation.

    Main Methods:

    • Retrospective analysis of 24 adult patients undergoing a second tumor removal surgery.
    • Evaluation of survival time and Karnofsky rating (KR) as key outcome measures.
    • Statistical analysis to determine the significance of preoperative neurological status, interoperative interval, age, sex, and tumor location on survival.

    Main Results:

    • Median survival after reoperation was 14 weeks; only 5 patients survived 6 months or longer.
    • Preoperative Karnofsky rating (KR) was the most significant determinant of survival (p = 0.02).
    • Patients with KR ≥ 60 had a median survival of 22 weeks, compared to 9 weeks for those with KR < 60.

    Conclusions:

    • Reoperation for supratentorial glioblastoma/anaplastic astrocytoma yields the best results when the Karnofsky rating (KR) is at least 60 and the interval between operations exceeds 6 months.
    • Reoperation is not recommended for patients with a preoperative KR below 60.
    • Approximately one-third of carefully selected patients may achieve a KR of at least 60 for 6 months post-reoperation.
