Abstract : We give an overview of the current status of the anomalous dimensions of composite operators when mixing with total derivative ones is included. These anomalous dimensions determine the scale dependence of non-perturbative functions appearing in the cross-sections of hard exclusive scattering processes, such as the generalized parton distributions in deeply-virtual Compton scattering. The computation is based on a consistency relation between the anomalous dimensions which is a direct consequence of the renormalization structure of the operators. The method was previously used to obtain the anomalous dimensions in the large-nf approximation, and during the present talk a summary will be given of the current status beyond this limit.
