RESUMEN
Biobanking is a relatively newly recognized and innovative branch of science, which includes the collection of samples and associated data from hospitals, diagnostic centers, and voluntary donations for biomedical and environmental research. It involves diverse stakeholders at the junction of society, science, ethics, law, and politics. A key element in the success of a biobank is the trust and support of public donors, clinicians, and scientists. To achieve trust, it is important to implement strategies that can increase biobank awareness in common people, and different types of communities. Biobank laws and regulations and transparent governance by the biobanks are also crucial to achieving public trust.

Purposes: Most molecular-based published studies on breast cancer do not adequately represent the unique and diverse genetic admixture of the Latin American population. Searching for similarities and differences in molecular pathways associated with these tumors and evaluating its impact on prognosis may help to select better therapeutic approaches. Patients and Methods: We collected clinical, pathological, and transcriptomic data of a multi-country Latin American cohort of 1,071 stage II-III breast cancer patients of the Molecular Profile of Breast Cancer Study (MPBCS) cohort. The 5-year prognostic ability of intrinsic (transcriptomic-based) PAM50 and immunohistochemical classifications, both at the cancer-specific (OSC) and disease-free survival (DFS) stages, was compared. Pathway analyses (GSEA, GSVA and MetaCore) were performed to explore differences among intrinsic subtypes. Results: PAM50 classification of the MPBCS cohort defined 42·6% of tumors as LumA, 21·3% as LumB, 13·3% as HER2E and 16·6% as Basal. Both OSC and DFS for LumA tumors were significantly better than for other subtypes, while Basal tumors had the worst prognosis. While the prognostic power of traditional subtypes calculated with hormone receptors (HR), HER2 and Ki67 determinations showed an acceptable performance, PAM50-derived risk of recurrence best discriminated low, intermediate and high-risk groups. Transcriptomic pathway analysis showed high proliferation (i.e. cell cycle control and DNA damage repair) associated with LumB, HER2E and Basal tumors, and a strong dependency on the estrogen pathway for LumA. Terms related to both innate and adaptive immune responses were seen predominantly upregulated in Basal tumors, and, to a lesser extent, in HER2E, with respect to LumA and B tumors. Conclusions: This is the first study that assesses molecular features at the transcriptomic level in a multicountry Latin American breast cancer patient cohort. Hormone-related and proliferation pathways that predominate in PAM50 and other breast cancer molecular classifications are also the main tumor-driving mechanisms in this cohort and have prognostic power. The immune-related features seen in the most aggressive subtypes may pave the way for therapeutic approaches not yet disseminated in Latin America. Clinical Trial Registration: ClinicalTrials.gov (Identifier: NCT02326857).
RESUMEN
The SARS-CoV-2 pandemic, which caused a global outbreak of COVID-19 disease, has been a crisis of extraordinary proportions, causing serious impacts for research and public health. Biobanks have played a key important role in understanding the disease and response. In our article we will highlight the opportunities and risks of biobanks during and after the pandemic. The different aspects of safety and sustainability have and will be the main challenges for biobanks. Furthermore, the role of biobanks in biomedical research and public health has been emphasized as well as opportunities that have arisen for their participation in research.

Quality specimens from biobanks are key resources to support reproducible research. Sustaining biobanks requires robust management. We recently published a pilot survey that indicated that over half the participating biobanks had business plans in place and another third were working on business planning. While the results provided a clue to the status of business planning in biobanking, it was concluded that a longer and more in-depth survey and analysis were required. In April 2017, an extended survey was distributed worldwide in English, French, Chinese, German, and Spanish, through multiple channels. The survey was built using the Survey Monkey tool. Our hypothesis was that those biobanks that already have a business plan also have a more professional management structure. The questions were designed to understand more details about each biobank's business operations and communications. A total of 276 biobanks participated (China 65, France 40, United States 34, Spain 27, Germany 24, Australia 23, and rest of the world 63). About two thirds of the biobanks were established in the last 10 years. The responses provided data on the size of biobanks answering the survey, their status of business planning, and how and through what mediums they are communicating with customers. Biobanks with a business plan or preparing to have one showed a clear trend of having a customer strategy for marketing the samples and communicating with customers. No trend could be seen regarding websites and activities in social media. We confirmed our hypothesis that biobanks that have or are in the process of preparing a business plan are showing a trend toward more professional structures. In the biobanking community, the business mind-set and use of the business plan as a management tool have not quite arrived.

Biobanks are now in the spotlight as key enablers supporting preclinical, clinical, and environmental research. Awareness of their value has increased along with the need for these infrastructures to be sustained through business-focused practices. Following our 2017 pilot survey on biobank business planning, we initiated a more comprehensive 38-question multiple-language worldwide survey on biobank sustainability. Two hundred seventy-six biobanks of various sizes and stages of business planning (in place, in progress or none) responded. About two-thirds were established in the last 10 years. Survey results confirm our hypothesis that biobanks with business plans or preparing such plans are trending toward more professional structures. Specific survey data focusing on performance metrics and utilization, as related to sustainability, are presented. Biobanks most frequently measured basic performance metrics (sample utilization, samples collected, samples distributed, internal projects supported). Metrics less often reported included sample and data quality, cost recovery, citations, and publications, typically correlating with higher levels of biobank complexity and professionalism. Biobanks reported supporting projects for both internal and external use, with support of projects within their own organizations as the main driver of biobanks, independent of business plan status. Having a business plan seemed to be a key factor for biobanks that had developed sustained support for external commercial projects. While under half of the biobanks reported both target and actual utilization rates, the responses provided valuable data on utilization. Target utilization rates were much higher (2.5 to 5 times higher) than the rate of actual use. Many of the biobanks report less than 10% utilization. Biobanks with low utilization rates make sustainability a very distant and likely unreachable goal. Our survey has provided some basic data about biobank business planning globally. Continued research should be done, with the data and information shared within the community for the good of all biobank stakeholders.

Biobanks provide a critical infrastructure to support research in human health. Biospecimens and their accompanying data are increasingly needed to support biomedical research and clinical care. The original text was initially published in the Handbook for Cancer Research in Africa. The value of this publication is great as it underlines the importance of biobanks in Africa as a key resource to increase quality scientific research and participate in global health research. Therefore, a revision to extend these principles to other low resource contexts, to include updated material and references and add the topic of biobank sustainability were relevant.

Conventionally, biobanks supporting clinical research studies have preserved serum, plasma, urine, saliva, a variety of tissue types, and stool. With the emergence of increasingly sophisticated technologies for analyzing single cells, there is growing interest in preserving viable blood cells for future functional studies. The new All of Us Research Program (formerly the Precision Medicine Initiative Cohort Program) biobank plans to house samples from a million or more individuals as part of a cohort with rich phenotypic data and longitudinal follow-up ( www.nih.gov/research-training/allofus-research-program ). Storage of viable cells for future single-cell analysis offers the promise of new biology, discovery of novel biomarkers, and advances toward the goal of precision medicine. A workshop was held in the summer of 2016 to evaluate the case for preservation of viable mononuclear blood cells and its feasibility within the collection plan for the biobank.

The notion of attributing user fees to researchers for biospecimens provided by biobanks has been discussed frequently in the literature. However, the considerations around how to attribute the cost for these biospecimens and data have, until recently, not been well described. Common across most biobank disciplines are similar factors that influence user fees such as capital and operating costs, internal and external demand, and market competition. A biospecimen user fee calculator tool developed by CTRNet, a tumor biobank network, was published in 2014 and is accessible online at www.biobanking.org . The next year a survey was launched that tested the applicability of this user fee tool among a global health research biobank user base, including both cancer and noncancer biobanking. Participants were first asked to estimate user fee pricing for three hypothetical user scenarios based on their biobanking experience (estimated pricing) and then to calculate fees for the same scenarios using the calculator tool (calculated pricing). Results demonstrated variation in estimated pricing that was reduced by calculated pricing. These results are similar to those found in a similar previous study restricted to a group of Canadian tumor biobanks. We conclude that the use of a biospecimen user fee calculator contributes to reduced variation of user fees and for biobank groups (e.g., biobank networks), could become an important part of a harmonization strategy.
