ERIC aims to promote and/or advance the assessment of TP53 gene aberrations for diagnostic purposes by educating the hematological community about; 1) the need for performing such tests in all cases that require therapy, in both first and subsequent lines of treatment; 2) the quality of the appropriate techniques to be utilized by diagnostic laboratories to ensure reliable and comparable results across different institutions in Europe and elsewhere.
Ultimately, this will improve optimal patient care and will increase the availability of relevant tests, allowing clinical study groups, as well as the pharmaceutical industry, to focus on these particularly difficult-to-treat CLL patients and channel them to clinical trials aimed at further improving long-term outcomes.
The project is addressed to all scientific personnel working in laboratories performing diagnostics for patients with CLL including: those who have never performed the analyses in the past, those who have recently introduced novel diagnostics and need reassurance on the correctness of the procedure, and those already experienced in their use who need official certification of quality control for applied methodologies. It is also aims to increase physicians’ awareness of the need to test all CLL patients requiring therapy in order to select the most appropriate treatment for each case. The proposal will accomplish its goals using the following approaches:
WORKING PLAN AND SPECIFIC OBJECTIVES
The project will accomplish its goals using the following approaches:
1ST ERIC WORKSHOP ON TP53 ANALYSIS IN CLL
A hands-on workshop was held in Brno, (Czech Republic), from 1-3 October 2015, in which participants were introduced to both the scientific rationale for performing these diagnostic procedures and the basic principles of the relevant methodologies. This was the first ERIC TP53 Workshop on TP53 Analysis in Chronic Lymphocytic Leukemia. Its main goal was to address important biological, methodical and clinical questions relating to the role of TP53 abnormalities in Chronic Lymphocytic Leukemia. More than 130 participants from various countries were given the opportunity to learn, share ideas and discuss the current state of knowledge and future perspectives in a friendly atmosphere during the scientific sessions and social events. During the workshop, participants had a chance to explore the actual practical work, from the sample collection to the drafting of the final clinical report. This activity could also be extended to clinical study groups and industry partners to improve both the standardization of the assay and the interpretation of the results within investigator – or company-driven clinical trials.
2ND TP53 ERIC WORKSHOP ON TP53 ANALYSIS IN CLL
The second TP53 Workshop on TP53 Analysis in Chronic Lymphocytic Leukemia was held in Stresa, (Italy) from 7-8 November 2017. At this Workshop there was a special emphasis placed on both theoretical and practical aspects of p53 inactivation in leukemic cells, introduction of TP53 mutational analysis into the clinical diagnostics and data interpretation. There was also Panel discussions and an interactive workshop focusing on the practical aspects of TP53 analysis. The aim of the workshop was to attract top experts in the field to share their knowledge and experience. This event was organized by the Certifying Centre in Brno, Czech Republic who also organized the first TP53 Workshop.
ESTABLISHMENT AND EXPANSION OF THE TP53 NETWORK
A network of reference laboratories has been established and is providing ongoing supervision and advice to individual laboratories that need to set-up, improve or consolidate the diagnostic techniques for the assessment of TP53 gene aberrations in their laboratories. The current Network has grown and now consists of three Certifying Centers (Czech Republic, Germany and Sweden and Nordic Countries), for internal certification of the requesting labs, and eleven Reference Centers (originally eight), one for each participating country or region (Czech Republic, Denmark, France, Germany, Greece, Italy, Spain, Sweden and Nordic Countries, Switzerland, The Netherlands, United Kingdom), that will coordinate the work and ensure the overall quality of the network. The different centers will either help to set up the diagnostic procedures or directly perform the analyses for requesting laboratories while the latter are in the process of implementing them in their own facilities. ERIC is now a truly global network but aims to further expand this network in the future.
CERTIFICATION OF TP53 MUTATIONAL ANALYSIS
The certification process can be summarized as follows:
PHASE 1: COMPLETION OF PARTICIPATION FORM
Interested laboratories should complete the participation form in order to be eligible for the next certification round. The participation form can be found by clicking here
PHASE 2: LABORATORY AND BIOINFORMATICS ANALYSIS
Once the list of participating laboratories has been defined, these laboratories will be asked to confirm their shipping details and confirm that they still wish to participate.
The certifying centre will prepare the quality control material – genomic DNA from 5 CLL cases of diverse TP53 status – and ship this to the corresponding laboratories.
Laboratories will be informed as to when they should receive their samples and will be provided with instructions (via email) as to how to proceed with the certification process. The laboratories will be provided with the samples and all the necessary guidelines in order to carry out the analysis. The analysis will be completed through the submission of an online personalized form which must be sent within 3 months.
PHASE 3: EVALUATION & DECISION
The results will be analysed by the Certifying Centre in terms of both the analysis per se and the interpretation of the findings. Successful laboratories will be provided with a certificate (either Standard or Good Laboratory Practice) and a letter summarizing their performance and unsuccessful laboratories will be asked to reapply at the next round and be provided with necessary guidance.
SUMMARY: CERTIFICATION ROUNDS
Seven rounds of TP53 Certification have already been completed and the next round will be announced soon. The participation survey remains active for the whole year for those labs interested to participate in the next round. Should your lab be interested, then please ensure that you complete and send the Participation Form which can be found here
ONLINE WEB TOOLS
The following online web tools have been created and are available in order to provide laboratories with guidance and assistance to achieve reliable and comparable results for TP53 mutational analysis.
ONLINE HELP DESK
The online help desk has been specifically set up for laboratories facing any difficulties during the analysis. It provides methodological as well as interpretation consultation.
FREE SOFTWARE OF SANGER ANALYSIS DATA (GLASS)
This software helps laboratories with the analysis of Sanger Sequencing data.
