Purpose: Glioblastoma (GBM) is the most common aggressive mice with or without a brain tumor. The survival of young and old primary malignant brain tumor in adults with a median age of onset wild-type or transgenic (INK-ATTAC) mice with a brain tumor was of 68 to 70 years old. Although advanced age is often associated with evaluated after treatment with or without senolytics and/or poorer GBM patient survival, the predominant source(s) of malimmunotherapy. adaptive aging effects remains to be established. Here, we studied Results: Human patients with GBM ≥65 years of age had a ntratumoral and extratumoral relationships between adult patients significantly decreased survival compared with their younger with GBM and mice with brain tumors across the lifespan. counterparts.
