dMR During First Line Treatment of Non Squamous Lung Cancer: Time Course and Prognostic and Predictive Impact. (BevMar)

To date, there are no methods to reliably select which patients with non-squamous non-small cell lung cancer (NSCLC) that benefit most from treatment with bevacizumab. Data have shown that high levels of plasma VEGF are prognostic and correlates with a worse disease outcome in some tumour types, including advanced NSCLC.

Recent data are suggestive of a predictive value of imaging techniques for early detection of antiangiogenic treatment efficacy in different cancers. To our knowledge there are no presented data available on correlation between changes in diffusion-weighted MR and response to bevacizumab treatment in lung cancer. The current study is designed as a pilot study to prospectively investigate changes in MR variables during treatment with bevacizumab and to detect signals of prognostic and/or predictive value of MR changes during treatment.
