Structural requirements of research tissue banks derived from standardized project surveillance

Basic principles of biobanking: from biological samples to precision medicine for patients

The term "biobanking" is often misapplied to any collection of human biological materials (biospecimens) regardless of requirements related to ethical and legal issues or the standardization of different processes involved in tissue collection. A proper definition of biobanks is large collections of biospecimens linked to relevant personal and health information (health records, family history, lifestyle, genetic information) that are held predominantly for use in health and medical research. In addition, the International Organization for Standardization, in illustrating the requirements for biobanking (ISO 20387:2018), stresses the concept of biobanks being legal entities driving the process of acquisition and storage together with some or all of the activities related to collection, preparation, preservation, testing, analysing and distributing defined biological material as well as related information and data. In this review article, we aim to discuss the basic principles of biobanking, spanning from definitions to classification systems, standardization processes and documents, sustainability and ethical and legal requirements. We also deal with emerging specimens that are currently being generated and shaping the so-called next-generation biobanking, and we provide pragmatic examples of cancer-associated biobanking by discussing the process behind the construction of a biobank and the infrastructures supporting the implementation of biobanking in scientific research.

Drafting biological material transfer agreement: a ready-to-sign model for biobanks and biorepositories

PURPOSE

Due to the scarcity of publications, guidelines, and harmonization among national regulations, biobanks and institutions face practical and theoretical issues when drafting a material transfer agreement (MTA), the fundamental tool to regulate the successful exchange of biosamples and information. Frequently researchers do not execute MTAs because of a general lack of knowledge about this topic. It is thus critical to develop new models to prevent loss of traceability and opportunities both for researchers and biobanks, their exposure to various risks, and delays in transferring biomaterials.

METHODS

Through the involvement of institutional groups and professionals with multidisciplinary expertise, we have drawn up a ready-to-sign MTA for the CRO-Biobank (the biobank of the National Cancer Institute, CRO, Aviano), a standardized template that can be employed as a ready-to-use model agreement.

RESULTS

The team identified the essential components to be included in the MTA, which comprise i) permissions, liability and representations; ii) custodianship and distribution limitations; iii) appropriate use of materials, including biosafety concerns; iv) confidentiality, non-disclosure, and publications; v) intellectual property protection for both the provider and recipient.

CONCLUSIONS

This paper aims to be an unabridged report (among the few works in the existing literature) providing a description of the whole process related to the formation of an MTA. Biobanks and institutions may consider adopting our ready-to-sign form as a standard model. The article discusses the most important issues tackled during the drafting of the document, thus proposing an operative approach for other institutions that face the same problems.

[Maintainance of a research tissue bank. (Infra)structural and quality aspects]

The availability of high quality human tissue samples and access to associated histopathological and clinical data are essential for biomedical research. Therefore, it is necessary to establish quality assured tissue biobanks that provide high quality tissue samples for research purposes. This entails quality concerns referring not only to the biomaterial specimen itself but encompassing all procedures related to biobanking, including the implementation of structural components, e.g. ethical and legal guidelines, quality management documentation as well as data and project management and information technology (IT) administration. Moreover, an integral aspect of tissue biobanks is the quality assured evaluation of every tissue specimen that is stored in a tissue biobank and used for projects to guarantee high quality assured biomaterial.

Challenges for quality management in implementation, maintenance, and sustainability of research tissue biobanks

Availability of high-quality human tissue samples and access to associated histopathological and clinical data is essential for basic and translational biomedical research, especially in areas of personalized medicine, drug, and biomarker development and mechanistically oriented biomedical research projects. Therefore, it is pivotal to establish and maintain quality-assured tissue biobanks that provide high-quality biomaterial to research thereby increasing the impact and reliability of scientific results. Quality concerns do not only address the biomaterial specimen itself but include all biobanking-related procedures. Tissue biobanks thus face essential challenges that encompass the implementation of adequate structural components, documentation of tissue sample collection and storage (procedures), as well as data and project management and IT. An integral and indispensable component of tissue biobanks is expert-driven evaluation (entry and exit controls) of tissue specimen to guarantee provision of high-quality assured biomaterials.

[Structure of biobanks for urological research]

Biomedical research plays an important role in the development of novel diagnostic procedures, drugs and treatment strategies with regard to cancerous and chronic inflammatory diseases. Biobanks are essential tools in this process. The complex structures and benefits of biobanks are presented in this article.
