Letter to the Editor ‐ responses to Weisntein D, Simon M, Yehezkel E, Laron Z, Werner H. Insulin analogues display IGF‐I‐like mitogenic and antiactivity in cultured cancer cells

: We thank the team of Eli Lilly and Company for their critical appraisal of our study and for giving us the opportunity to clarify a number of points [1]. We agree with Kazda et al. that randomized clinical trials will best address any direct relationship between insulin analogues and cancer in man. We do not question the fact that tight control of blood glucose has dramatically advanced the lives of patients with diabetes. This article is protected by copyright. All rights reserved.
