Gene fusions are nucleotide sequences formed due to errors in replication and transcription control. These errors, resulting from chromosomal translocation, transcriptional errors or trans-splicing, vary from cell to cell. The identification of fusions has become critical as key biomarkers for disease diagnosis and therapy in various cancers, significantly influencing modern medicine.

Article Synopsis
  • * The study involved 20 patients whose tumors were assessed using both the established RANO criteria and the newer 3D volumetric growth rate (3DVGR) method, showing that bevacizumab was effective according to both approaches.
  • * Findings indicate that while RANO is widely used, 3DVGR may provide more accurate measurements for irregularly shaped tumors, suggesting that bevacizumab could be a valuable treatment option.

Purpose: Angiogenesis is a crucial step in tumorigenesis of glioblastoma (GBM). Bevacizumab, an anti-vascular endothelial growth factor drug, is approved for second-line therapy for GBM. Glioma stem cells, presumably the cell of origin of GBM, take an active role in angiogenesis.

Introduction: Historically, patients with brain metastasis (BM) have been excluded from clinical trials investigating treatments for non-small cell lung cancer (NSCLC) due to their unfavorable prognosis. Advanced treatments have increased survival prospects for NSCLC patients with BM. This study evaluated the life expectancy of NSCLC patients with and without BM in the context of contemporary treatments.
