Clinical research is an essential work to improve the treatment of oncological patients. This work is fruitless if it is carried out without cooperation projects between several hospitals. The cooperative effort is especially important in handling sarcomas, not only because of their rarity, but also due to their biological heterogeneity and the variability of their clinical behavior.
