Prolonged activity of bevacizumab in adenocarcinoma of the lung with multiple brain metastases.

Patients with lung cancer having multiple brain metastases have poor outcomes. We present long-term disease treatment in a 60-year-old woman having greater than thirty brain metastases of NSCLC adenocarcinoma with a mutant allele of EGFR treated with differing chemotherapies including erlotinib, but disease response in the brain only with bevacizumab. Although initially restricted in use, increasing clinical reports have demonstrated safety of bevacizumab use in brain-involved cancer patients. Our case highlights that disease response to bevacizumab is similar in the brain to systemic disease and likely overcomes anatomical barriers that can limit other therapeutic agents.
