National guidelines and evidence based medicine

In the international scenario of evidenced based medicine oncologic treatments are crucially involved, since clinical trials are of utmost importance in oncology and levels of recommendations are their direct consequence. As for the majority of cancers, the result of evidence based medicine in gastric cancer field is very often a guide-lines document. Such a consensus file is mostly reached within national associations of specialists dedicated to the treatment of gastric cancer. The aim of our web round table is to try to compare many of these national guide-lines, contacting their own Authors and to have a feed-back for all the users of them on how much these guide-lines are useful and followed in every single country. Our objective would like to be not a scientific discussion on the single topics expressed in the guide-lines, but how such guide-lines were defined, how much evidence based medicine was crucial in this definition and if it could be possible to extend this way of take steps from a national setting to an international scale.
