An exceptional overall survival using bevacizumab beyond progression in a patient with non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) is the most common malignancy and the leading cause of cancer death worldwide. In this report, we describe a patient with NSCLC who was treated with continuation of Bevacizumab (Bev) beyond progression to first-line Bev-based chemotherapy. The prolonged treatment with Bev by continuing the inhibition of VEGF beyond first-progression has a strong rationale. Nevertheless, few data exist regarding the efficacy and safety of Bev beyond first line of chemotherapy progression in NSCLC patients. Further studies including a large number of patients are needed, in order to select patients who could benefit from this approach.
