Pancreatic neuroendocrine tumors. Prognostic factors

We thank Modesto Varas et al. for their opportune comments with regard to the oncologic outcomes of our series of patients undergoing surgery for pancreatic neuroendocrine tumors (PNET). We agree with Varas et al. in relation to the increase in non-functional tumors (73%) and the incidental form of presentation (44%). These figures are in line with those presented in most series.
