Aims

The SIOPEN Circulating RNA Committee collaborates to develop and validate high-precision minimally invasive methods to objectively assess disease status and patient response to therapy, with the goal of improving outcomes for children with neuroblastoma.

Since the bone marrow is a common site of metastasis and relapse, our research has focused on biomarkers in the bone marrow, peripheral blood stem cells and blood.

The description and validation of clinically informative biomarkers in blood is particularly attractive, as this could provide a minimally invasive test for prognostication and monitoring of children throughout the disease course. This is exemplified by outputs of our prospective quality-controlled study, examining the prognostic and predictive value of the adrenergic neuroblastoma mRNAs tyrosine hydroxylase and paired-like homeobox 2B mRNAs in blood and bone marrow from children with neuroblastoma entered into HR-NBL-1/SIOPEN (1-4).

We are also investigating the role of small RNAs including microRNAs, which may be important for prognostication and might also identify new targets for the development of novel therapeutics to eradicate metastatic drug-resistant disease. In a proof of concept study microRNAs in plasma-derived exosomes have been shown to predict response to induction-chemotherapy and may be markers of sensitivity to specific drugs.

To ensure the quality of our studies the SIOPEN CRC establishes standard operating procedures for sample collection, transport, storage and analyses.
We maintain quality assurance within the SIOPEN CRC reference laboratories through biannual blinded quality control studies.

We are grateful to our collaborators who help with study design, data analyses and interpretation, including Dr Ulli Pötschger (Austria), Professor Walter Gregory (United Kingdom), Ms Aimee Houlton (United Kingdom), Dr Stefano Parodi (Italy), Professor Keith Wheatley (United Kingdom), national coordinators, Professor Dominique Valteau-Couanet and Professor Ruth Ladenstein.
