Journal article (peer-reviewed)abstract
- Molecular pathology is an integral part of daily diagnostic pathology and used for classification of tumors, for prediction of prognosis and response to therapy, and to support treatment decisions. For these reasons, analyses in molecular pathology must be highly reliable and hence external quality assessment (EQA) programs are called for. Several EQA programs exist to which laboratories can subscribe, but they vary in scope, number of subscribers, and execution. The guideline presented in this paper has been developed with the purpose to harmonize EQA in molecular pathology. It presents recommendations on how an EQA program should be organized, provides criteria for a reference laboratory, proposes requirements for EQA test samples, and defines the number of samples needed for an EQA program. Furthermore, a system for scoring of the results is proposed as well as measures to be taken for poorly performing laboratories. Proposals are made regarding the content requirements of an EQA report and how its results should be communicated. Finally, the need for an EQA database and a participant manual are elaborated. It is the intention of this guideline to improve EQA for molecular pathology in order to provide more reliable molecular analyses as well as optimal information regarding patient selection for treatment.

Research review (peer-reviewed)abstract
- Cancer omics data are exponentially created and associated with clinical variables, and important findings can be extracted based on bioinformatics approaches which can then be experimentally validated. Many of these findings are related to a specific class of non-coding RNA molecules called microRNAs (miRNAs) (post-transcriptional regulators of mRNA expression). The related research field is quite heterogeneous and bioinformaticians, clinicians, statisticians and biologists, as well as data miners and engineers collaborate to cure stored data and on new impulses coming from the output of the latest Next Generation Sequencing technologies. Here we review the main research findings on miRNA of the first 10 years in colon cancer research with an emphasis on possible uses in clinical practice. This review intends to provide a road map in the jungle of publications of miRNA in colorectal cancer, focusing on data availability and new ways to generate biologically relevant information out of these huge amounts of data.
