An International Society for Cell and Gene Therapy Mesenchymal Stromal Cells (MSC) Committee perspectives on International Standards Organization/Technical Committee 276 Biobanking Standards for bone marrow-MSCs and umbilical cord tissue-derived MSCs for research purposes.

The rapidly growing field of mesenchymal stromal cell (MSC) basic and translational research requires standardization of terminology and functional characterization. The International Standards Organization's (ISO) Technical Committee (TC) on Biotechnology, working with extensive input from the International Society for Cells and Gene Therapy (ISCT), has recently published ISO standardization documents that are focused on biobanking of MSCs from two tissue sources, Wharton's Jelly, MSC(WJ) and Bone Marrow, MSC(M)), for research and development purposes and development. This manuscript explains the path towards the consensus on the following two documents: the Technical Standard ISO/TS 22859 for MSC(WJ) and the full ISO Standard 24651 for MSC(M) biobanking. The ISO standardization documents are aligned with ISCT's MSC committee position and recommendations on nomenclature because there was active input and incorporation of ISCT MSC committee recommendations in the development of these standards. The ISO standardization documents contain both requirements and recommendations for functional characterization of MSC(WJ) and MSC(M) using a matrix of assays. Importantly, the ISO standardization documents have a carefully defined scope and are meant for research use of culture expanded MSC(WJ) and MSC(M). The ISO standardization documents can be updated in a revision process and will be systematically reviewed after 3-5 years as scientific insights grow. They represent international consensus on MSC identity, definition, and characterization; are rigorous in detailing multivariate characterization of MSCs and represent an evolving-but-important first step in standardization of MSC biobanking and characterization for research use and development.

Quality matters: International standards for biobanking.

Human biospecimens provide the basis for research, leading to a better understanding of human disease biology and discovery of new treatments that are tailored to individual patients with cancer or other common complex diseases. The collection, processing, preservation, storage and providing access to these resources are key activities of biobanks. Biobanks must ensure proper quality of samples and data, ethical and legal compliance as well as transparent and efficient access procedures. The standards for biobanking outlined herein are intended to be implemented in biobanks and to supply researchers with high-quality samples fitted for an intended use.

Biobanks for life sciences and personalized medicine: importance of standardization, biosafety, biosecurity, and data management.

Biological samples such as tissues, blood and other body fluids, plants or seeds, prokaryotic and eukaryotic cells or isolated biomolecules as well as associated data are the essential raw material for research and development in medicine, biotechnology and agriculture. The collection, processing, preservation, and storage of these resources, in addition to provision of access, are key activities of biobanks or biological resource centres. Biobanks have to ensure proper quality of samples and data, ethical and legal compliance as well as transparent and efficient access procedures. In this context the review places special emphasis on pre-analytical procedures and international standards, which are essential to improving analytical data reliability and reproducibility, as well as on the increasing importance of data management. These requirements of biobanks are demonstrated using the example of pathogen-containing and microbiome biobanks, and refer to needs in cancer research and development.

[Tumor banks and complex data management: Current and future challenges]. / Biobanques tumorales et gestion des données complexes : enjeux actuels et futurs.

Tumor banks are asked to clinical and translationnal research project development in oncology. They strongly participate to the assessment, then to the validation of diagnostic, prognostic and predictive biomarkers. The progressive change of these structures leads to induce a professionalization of their functioning and to identify them as key actors in oncology by the stakeholders of the public and private worlds. The progresses made in biotechnologies and therapeutics are rapidly modifying the impact and the proper functioning of the biobanks. These latter are now facing different challenges, in particular for their sustainability. Among the major issues, the integration of the clinical and biological data becoming increasingly complex leads to urgently consider an optimization of the role of different biobanks in France. Their goal is to be an attractive counterpart face to the international competition. The purpose of this review is to briefly describe the current evolution of the biobanks, then their present and future challenges, and finally the role made by the pathologists in these new issues in oncology field.

The 9th Santorini Conference: Systems Medicine, Personalised Health and Therapy. "The Odyssey from Hope to Practice", Santorini, Greece, 30 September⁻3 October 2018.

The 9th traditional biannual conference on Systems Medicine, Personalised Health & Therapy-"The Odyssey from Hope to Practice", inspired by the Greek mythology, was a call to search for practical solutions in cardio-metabolic diseases and cancer, to resolve and overcome the obstacles in modern medicine by creating more interactions among disciplines, as well as between academic and industrial research, directed towards an effective 'roadmap' for personalised health and therapy. The 9th Santorini Conference, under the Presidency of Sofia Siest, the director of the INSERM U1122; IGE-PCV (www.u1122.inserm.fr), University of Lorraine, France, offered a rich and innovative scientific program. It gathered 34 worldwide distinguished speakers, who shared their passion for personalised medicine with 160 attendees in nine specific sessions on the following topics: First day: The Odyssey from hope to practice: Personalised medicine-landmarks and challenges Second day: Diseases to therapeutics-genotype to phenotype an "-OMICS" approach: focus on personalised therapy and precision medicine Third day: Gene-environment interactions and pharmacovigilance: a pharmacogenetics approach for deciphering disease "bench to clinic to reality" Fourth day: Pharmacogenomics to drug discovery: a big data approach and focus on clinical data and clinical practice. In this article we present the topics shared among the participants of the conference and we highlight the key messages.

Establishing a Dedicated Lung Cancer Biobank at the University Center Hospital of Nice (France). Why and How?

Lung cancer is the major cause of death from cancer in the world and its incidence is increasing in women. Despite the progress made in developing immunotherapies and therapies targeting genomic alterations, improvement in the survival rate of advanced stages or metastatic patients remains low. Thus, urgent development of effective therapeutic molecules is needed. The discovery of novel therapeutic targets and their validation requires high quality biological material and associated clinical data. With this aim, we established a biobank dedicated to lung cancers. We describe here our strategy and the indicators used and, through an overall assessment, present the strengths, weaknesses, opportunities and associated risks of this biobank.

Ensuring the Safety and Security of Frozen Lung Cancer Tissue Collections through the Encapsulation of Dried DNA.

Collected specimens for research purposes may or may not be made available depending on their scarcity and/or on the project needs. Their protection against degradation or in the event of an incident is pivotal. Duplication and storage on a different site is the best way to assure their sustainability. The conservation of samples at room temperature (RT) by duplication can facilitate their protection. We describe a security system for the collection of non-small cell lung cancers (NSCLC) stored in the biobank of the Nice Hospital Center, France, by duplication and conservation of lyophilized (dried), encapsulated DNA kept at RT. Therefore, three frozen tissue collections from non-smoking, early stage and sarcomatoid carcinoma NSCLC patients were selected for this study. DNA was extracted, lyophilized and encapsulated at RT under anoxic conditions using the DNAshell technology. In total, 1974 samples from 987 patients were encapsulated. Six and two capsules from each sample were stored in the biobanks of the Nice and Grenoble (France) Hospitals, respectively. In conclusion, DNA maintained at RT allows for the conservation, duplication and durability of collections of interest stored in biobanks. This is a low-cost and safe technology that requires a limited amount of space and has a low environmental impact.

Measuring the contribution of tumor biobanks to research in oncology: surrogate indicators and bibliographic output.

The number of biobanks, in particular hospital-integrated tumor biobanks (HITB), is increasing all around the world. This is the consequence of an increase in the need for human biological resources for scientific projects and more specifically, for translational and clinical research. The robustness and reproducibility of the results obtained depend greatly on the quality of the biospecimens and the associated clinical data. They also depend on the number of patients studied and on the expertise of the biobank that supplied the biospecimens. The quality of a research biobank is undoubtedly reflected in the number and overall quality of the research projects conducted with biospecimens provided by the biobank. Since the quality of a research project can be measured from the impact factor of resulting publications, this also provides some indication of the quality of a research biobank. It is necessary for the biobank community to define "surrogate" quality indicators, and to establish systems of evaluation in relation to current and future resource requirements. These indicators will help in the realistic assessment of biobanks by institutions and funding bodies, and they will help biobanks demonstrate their value, raise their quality standards, and compete for funding. Given that biobanks are expensive structures to maintain, funding issues are particularly important, especially in the current economic climate. Use of performance indicators may also contribute to the development of a biobank impact factor or "bioresource research impact factor" (BRIF). Here we review four major categories of indicators that appear to be useful for the evaluation of a(m) HITB (quality, activity, scientific productivity, and "visibility"). In addition, we propose a scoring system to measure the chosen indicators.

Correction of adolescent hyperkyphosis with posterior-only threaded rod compression instrumentation: is anterior spinal fusion still necessary?

STUDY DESIGN: Retrospective clinical and radiographic review. OBJECTIVE: To assess the need for anterior apical release and fusion before posterior threaded rod compression instrumentation and closing-wedge lamina resection for the treatment of adolescent hyperkyphosis. SUMMARY OF BACKGROUND DATA: Traditional treatment of adolescent hyperkyphosis has included a preliminary anterior release and fusion of apical disc segments to achieve and maintain better correction. METHODS: A total of 27 patients undergoing correction of adolescent hyperkyphosis with posterior threaded rod Texas Scottish Rite Hospital instrumentation was reviewed. Of the 27 patients, 19 had strict Sorensen criteria for Scheuermann kyphosis. There were 20 patients (group 1) who underwent posterior surgery only, while 7 (group 2) underwent same day preliminary open or endoscopic anterior release and fusion of 5-7 apical segments. A closing-wedge laminar resection was used to facilitate shortening of the posterior column. All but 2 patients were braced for up to 3 months after surgery. Preoperative, immediate postoperative, and final follow-up radiographs at 24-56 months postoperatively were analyzed for the amount and loss of correction of measured kyphosis, T2-T12 kyphosis, T10-L2 kyphosis, T12-S1 lordosis, C7 plumbline sagittal balance, and correction of Voutsinas index. RESULTS: There was no difference in the amount of correction achieved at final follow-up between the 2 groups (group 1 = 53%, group 2 = 46%, P = 0.47). There was also no difference (P = 0.84) in the amount of correction immediately after surgery compared to final follow-up. No patient lost more than 8 degrees correction after surgery. One asymptomatic rod fracture occurred, with no loss of correction, implying no pseudarthroses. Similarly, there were no differences in any of the other sagittal plane measurements between the 2 groups, except for Voutsinas index (VI) in which group 1 patients had better normalization (VI = 0.11) compared to group 2 (VI = 0.15, P =0.05). CONCLUSIONS: Traditional anterior/posterior fusion technique provides no additional improvement in radiographic outcome compared to posterior-only surgery for adolescent hyperkyphosis. Preliminary anterior release and fusion is no longer performed when correcting this deformity with a posterior column shortening procedure and threaded rod compression instrumentation.
