Tumor biobanks in translational medicine Gerardo Botti, Renato Franco, Monica Cantile, Gennaro Ciliberto and Paolo Antonio Ascierto*

Abstract The concept of tissue banking as a “bio-repository” aimed to collection, storing and distribution of human biological material and clinical information, is emerging as a successful strategy to support clinical and translational research. In particular, Tumor Biobanks represent a key resource for diagnosis, research and experimental therapies, especially for those correlated to clinical application of a new type of medicine known as “intelligent drugs”. Biobanks are not “spontaneous” collections, but they needs an institutional organization, basically a research unit, whose effectiveness and quality can be guaranteed only if it is carefully organized according to precise and shared rules.

Background In recent years, human biological material (e.g. tissues, cells, nucleic acids) obtained through common diagnostic procedures has become an important resource for biomedical research. In oncology, tumor tissue samples represent a precious tool for both clinical and experimental research. These tissues, preserved in optimal conditions, are an essential resource for identifying novel biomarkers for specific therapies [1]. Progress in genome and proteome research has also allowed us to differentiate multifactorial diseases previously considered as a single disorder into more precise diagnostic entities [2]. This achievement provides the basis for developing a more personalized treatment approach, optimizing clinical protocols and improving disease prevention. However, in order to ascertain the etiology of complex diseases, it is necessary to have access to a wide collection of biological samples with epidemiological, clinical, biological and molecular data from a large number of patients and healthy persons. The identification of standard operative procedures (SOPs) for tissue sampling, storage and collection of clinical data is an essential step in modern biobank management [3,4]. Sampling and collecting procedures must guarantee both the correct pathological diagnosis as well as the biological integrity of macromolecules (DNA, RNA and proteins) that represent the potential subject of investigation.

has shifted from the use of fresh/frozen tissues to those fixed in formalin/paraffin-embedded, both of which have been shown to be reliable sources for molecular analyses [5]. In addition, today’s biobank requires meaningful, relevant performance indicators that take into consideration more than just the amount of material collected. For instance, assessment should also consider the quality of collected biomaterial and the accompanying data, as well as the number and quality of projects that have made use of the material, and the number of resulting publications (al
