Statistical methodology for personalized medicine: New developments at EORTC Headquarters since the turn of the 21st Century

Since the creation of the EORTC Headquarters in 1974, major advances have been made in the methodology used in the design and analysis of cancer clinical trials. However, the speed of these developments in the fields of biology, medicine, and statistics has greatly increased since the turn of the 21st century. These changes have all become possible because of the increased computer power now available.The landscape of therapeutic anti-cancer development changed completely with the advent of the so-called “targeted agents” that treat the underlying molecular basis of the disease rather than the symptoms of tumor proliferation. The new challenges posed by the clinical development of these numerous new agents that are expected to work in often yet-to-be-identified subgroups of patients induced a new wave of methodological developments. Some of these were readily embraced by the EORTC Headquarters statistics department, while others met with opposition. Our assessment is still in progress in many areas. Trials tend to become increasingly complex so that their planning relies on an increasing number of unknown parameters that need to be monitored during the trial itself, one development being “adaptive” design methodology.Because the knowledge required to design these new and more complex clinical trials and associated research program spans more disciplines (biology, genomics, radiology) and involves specialized knowledge within those disciplines, continued success requires further developing our partnerships with specialized departments (imaging, bio-informatics, biology, etc.) within EORTC Headquarters and in EORTC affiliated centers as well as collaborations with specialized statisticians from academia.
