Requalifying a neuroblastoma collection built over 40 years.
A published study on the data needed to make historical paediatric biological samples available for research.
- samples assessed
- 21,389
- collection period
- 1984–2024
- retained under the study criteria
- 65%
The starting point
The Biological Sample Management Platform at Centre Léon Bérard was asked to integrate a historical neuroblastoma collection. Its associated information needed to be assessed to determine suitability for research use.
The work described in the study
- Assessment of the data associated with 21,389 samples.
- Identification of minimum information criteria for research use, drawing on applicable texts and reference documents.
- Application of a methodology to qualify samples against the defined criteria.
The documented result
65% of the samples met the criteria and were retained for future research. The study also highlighted a need to harmonise data management and interoperability practices.
What this experience demonstrates
A practical approach to collection requalification: review the available data, define usable criteria and document decisions about research readiness.
This case presents Laure Sanvee-Edoh’s research experience at Centre Léon Bérard. The figures describe the published study and its defined criteria.
