Meta-analysis of prognostic and predictive factors: Towards  individual participant data?

In this issue of EJC, Emil ter Veer et  al. [1] performed a systematic review and meta-analysis (MA) of randomised trials to identify prognostic and predictive factors of response to treatment in patients with metastatic oesophagogastric cancer, which gives an interesting overview of the various findings in this area. Notably, Lauren's classification is confirmed as a prognostic factor in most of the studies. With the development of personalised medicine, interest in prognostic and predictive factors has strongly increased.
