Gliosarcoma is a rare tumor of the central nervous system, consisting of gliomatous and sarcomatous elements. The glioblastoma can undergo a change in phenotype, transforming into a gliosarcoma, especially when the tumor has been treated with radiotherapy. Features unique to gliosarcoma compared to glioblastoma include their potential to appear similar to a meningioma at macroscopy, repeated reports of metastases and infrequency of EGFR mutations. We present a case of secondary gliosarcoma to emphasize on the specificities, essentially diagnostical of this rare entity.

Purpose: This study describes oncological outcomes and investigates prognostic factors for patients with gliosarcomas (GSM).
Methods: Histopathologically confirmed GSM patients who underwent treatment at five European institutions were retrospectively analyzed.
Results: We analyzed 170 patients with a median clinical follow-up time of 9.
Purpose: National Cancer Institute-Molecular Analysis for Therapy Choice (NCI-MATCH) was a multicohort phase 2 trial that assigned patients with advanced pretreated cancers to molecularly targeted therapies on the basis of tumor genomic testing. NCI-MATCH Arm A evaluated afatinib, an EGFR tyrosine kinase inhibitor (TKI) approved for advanced non-small cell lung cancer, in patients with tumors other than lung cancer harboring mutations.
Methods: Patients with advanced pretreated cancers other than lung cancer found to have selected actionable mutations were offered participation in Arm A.

Glioblastoma is the most common malignant primary brain tumor. Despite its infiltrative nature, extra-cranial glioblastoma metastases are rare. We present a case of a 63-year-old woman with metastatic glioblastoma in the lungs.
