This material can be stored in biobanks with the purpose of future research. Formalin-fixed tissue and also formalin-fixed paraffin embedded tissues are not suitable for all kinds of genetic studies on DNA or RNA, as formalin solution is well known for damaging nucleic acids. Therefore, for the purpose of conducting genetic studies, samples should be frozen in order to maintain a good quality of DNA/RNA over time Biobanks, in which waste samples are frozen, are undoubtedly expensive to maintain; however, it could be useful and important to consider their possible implication in particular research, regarding for example the tumor cells growth process, or when the procurement of samples is difficult. Regarding the relationship between informed consent and tissue collection, storage and research, two choices are possible： irreversible or reversible sample anonymization. These procedures involve different approaches and possible solutions that we will seek to define. Also, an important ethical aspect in regard to the role of biobanks is encouraging sample donation. For donors, seeing human sample being kept rather than discarded and seeing them become useful for research highlight the importance of the human body and improve the attitude towards donation. This process might also facilitate the giving of informed consent more trustfully and willingly.展开更多

From these patients, clinical data has been collected and patients have been followed through their cancer journey. Clinical data from these patients have been analyzed to identify any correlation between disease grade and outcome. In a small cohort, consisting of 407 patients, WCB has performed genetic analysis on patient primary tumor samples, identifying and characterizing mutations in the KRAS, NRAS, BRAF, PIK3CA and TP53 genes. The majority of patients with CRC who were consented to WCB were male with a mean age of 69 years and received surgery as the primary treatment for their disease. Pathology and disease-free survival data confirmed worse prognoses associated with more advanced disease. Heterogeneity within the primary tumor was explored in a subgroup of patients. Analysis of the KRAS and TP53 genes confirmed that more than 40% of CRC patients who were tested, harbored a genetic mutation within these genes in their primary tumor. Due to the limited sample size tested, most mutations did not show significant differences in disease-free survival, however, mutation of the BRAF gene did show a decrease in the disease specific survival, in keeping with the published data. Analysis of the patients diagnosed with CRC within the Biobank has provided us with valuable information on the status of CRC disease and treatment within the Welsh population. Over 12 years of consenting, we have witnessed significant changes in the information that researchers are interested in when sourcing samples for translational research. The development of new drugs that are tailored to the genetics of a cancer is emerging and at WCB we are focusing our collections on samples and data that meet the needs of this ever-evolving field.展开更多

文摘BACKGROUND:Previous studies have reported inconsistent results with positive,negative,and J-shaped associations between alcohol consumption and the hazard of aortic aneurysm and dissection(AAD).This study aimed to examine the connections between weekly alcohol consumption and the subsequent risk of AAD.METHODS:The UK Biobank study is a population-based cohort study.Weekly alcohol consumption was assessed using self-reported questionnaires and the congenital risk of alcohol consumption was also evaluated using genetic risk score(GRS).Cox proportional hazards models were used to estimate hazard ratios(HRs)with 95% confidence intervals(CIs)for the associations between alcohol consumption and AAD.Several sensitivity analyses were performed to assess the robustness of the results.RESULTS:Among the 388,955 participants(mean age:57.1 years,47.4% male),2,895 incident AAD cases were documented during a median follow-up of 12.5 years.Compared with never-drinkers,moderate drinkers(adjusted HR:0.797,95%CI:0.646-0.984,P<0.05)and moderate-heavy drinkers(adjusted HR:0.794,95%CI:0.635-0.992,P<0.05)were significantly associated with a decreased risk of incident AAD.Interaction-based subgroup analysis revealed that the protective effect of moderate drinking was reflected mainly in participants younger than 65 years and women.CONCLUSION:Our findings support a protective effect of moderate alcohol consumption on AAD,but are limited to participants younger than 65 years and women.
文摘Biological residual materials can be obtained from surgical activities or from pathological waste material collected for analysis and stored in formalin. This material can be stored in biobanks with the purpose of future research. Formalin-fixed tissue and also formalin-fixed paraffin embedded tissues are not suitable for all kinds of genetic studies on DNA or RNA, as formalin solution is well known for damaging nucleic acids. Therefore, for the purpose of conducting genetic studies, samples should be frozen in order to maintain a good quality of DNA/RNA over time Biobanks, in which waste samples are frozen, are undoubtedly expensive to maintain; however, it could be useful and important to consider their possible implication in particular research, regarding for example the tumor cells growth process, or when the procurement of samples is difficult. Regarding the relationship between informed consent and tissue collection, storage and research, two choices are possible： irreversible or reversible sample anonymization. These procedures involve different approaches and possible solutions that we will seek to define. Also, an important ethical aspect in regard to the role of biobanks is encouraging sample donation. For donors, seeing human sample being kept rather than discarded and seeing them become useful for research highlight the importance of the human body and improve the attitude towards donation. This process might also facilitate the giving of informed consent more trustfully and willingly.
文摘Over the last 12 years, the Wales Cancer Biobank (WCB) has consented to more than 2000 patients with colorectal cancer (CRC). From these patients, clinical data has been collected and patients have been followed through their cancer journey. Clinical data from these patients have been analyzed to identify any correlation between disease grade and outcome. In a small cohort, consisting of 407 patients, WCB has performed genetic analysis on patient primary tumor samples, identifying and characterizing mutations in the KRAS, NRAS, BRAF, PIK3CA and TP53 genes. The majority of patients with CRC who were consented to WCB were male with a mean age of 69 years and received surgery as the primary treatment for their disease. Pathology and disease-free survival data confirmed worse prognoses associated with more advanced disease. Heterogeneity within the primary tumor was explored in a subgroup of patients. Analysis of the KRAS and TP53 genes confirmed that more than 40% of CRC patients who were tested, harbored a genetic mutation within these genes in their primary tumor. Due to the limited sample size tested, most mutations did not show significant differences in disease-free survival, however, mutation of the BRAF gene did show a decrease in the disease specific survival, in keeping with the published data. Analysis of the patients diagnosed with CRC within the Biobank has provided us with valuable information on the status of CRC disease and treatment within the Welsh population. Over 12 years of consenting, we have witnessed significant changes in the information that researchers are interested in when sourcing samples for translational research. The development of new drugs that are tailored to the genetics of a cancer is emerging and at WCB we are focusing our collections on samples and data that meet the needs of this ever-evolving field.
文摘The importance and utility of biobanks has increased exponentially since their inception and creation.Initially used as part of translational research,they now contribute over 40%of data for all cancer research papers in the United States of America and play a crucial role in all aspects of healthcare.Multiple classification systems exist but a simplified approach is to either classify as population-based or disease-oriented entities.Whilst historically publicly funded institutions,there has been a significant increase in industry funded entities across the world which has changed the dynamic of biobanks offering new possibilities but also new challenges.Biobanks face legal questions over data sharing and intellectual property as well as ethical and sustainability questions particularly as the world attempts to move to a low-carbon economy.International collaboration is required to address some of these challenges but this in itself is fraught with complexity and difficulty.This review will examine the current utility of biobanks in the modern healthcare setting as well as the current and future challenges these vital institutions face.
文摘The coronavirus disease 2019(COVID-19)pandemic has highlighted the practice of infectious diseases biobanking,as well as existing challenges and opportunities.Thus,the future of infectious diseases biobanking in the post-pandemic era,shall not be an“entry-level version”of its counterpart in non-communicable diseases and large population cohorts,but incorporate the lessons learned.Biobanks constitute a critical research infrastructure supported by harmonized practices through the implementation of international standards,and perceived within the broader scope of healthcare's intersection with research.This perspective paper considers the barriers in biobanking and standardization of practices,as well as the emerging opportunities in the field.
