Clinical Pearls:

  • ICON7, a previous study, demonstrated that the addition of bevacizumab to carboplatin and paclitaxel improves progression-free survival (PFS), but not overall survival (OS) in first-line treatment of ovarian cancer
  • The goal of this analysis was to determine if response to bevacizumab was associated with the molecular classification as described by The Cancer Genome Atlas (TCGA) project.
  • The analysis identified four groups of tumors according to TCGA: differentiated, immunoreactive, mesenchymal and proliferative.
  • The proliferative and mesenchymal groups had a better response to bevacizumab and showed an improvement in PFS compared to the two other molecular subtypes.
