Early Prophylactic Versus Late Salvage Recombinant Human Endostatin in Managing Radiosurgery-Induced Brain Injury for NSCLC Brain Metastases
Primary Purpose:To preliminarily evaluate the efficacy and safety of recombinant human endostatin (Endostar) in the early prophylactic cohort (Cohort A) and late salvage cohort (Cohort B) for radiation-induced brain injury after stereotactic radiosurgery (SRS) in patients with non-small cell lung cancer (NSCLC) brain metastases, with a focus on the improvement rate of peritumoral brain edema.Secondary Purpose:To explore the effects of Endostar treatment on neurological function, quality of life, and survival outcomes in patients with NSCLC brain metastases following SRS; and to evaluate the convenience and compliance of the "72-hour continuous intravenous pump infusion" regimen.
Karnofsky performance status (KPS) score ≥60. [+7]
