The role of Bevacizumab in combination with chemotherapy for patients with advanced Non Small Cell Lung Cancer is well established. However the safety of Bevacizumab in this patient population with brain metastases has been unclear with the potential risk of CNS bleed. This issue was addressed in the PASSPORT trial which enrolled nonsquamous histology Non Small Cell Lung Cancer patients with treated brain metastases. The addition of bevacizumab to conventional chemotherapy or erlotinib in this trial was associated with a low incidence of CNS bleed suggesting that bevacizumab could be safely given for patients with Non Small Cell Lung Cancer with treated brain metastases.
