New 5-year European Parliament Term

The new 5-year European Parliament term 2019 to 2024 began with 751 new Members elected from 28 EU member States.  SIOP Europe is delighted that 13 of the European Parliament Members (MEPs) who endorsed our European Elections Manifesto have been re-elected.

SIOP Europe was present at the first plenary meeting of the new European Parliament in Strasbourg, France. It was an important opportunity to initiate contact and collaboration also with the newly elected MEPs who we hope will become the champions of the paediatric cancer cause in the next 5 years.

The European Parliament is one of the main co-legislators of the European Union together with the Council of the EU and the European Commission.  MEPs have an important say in shaping policies of high relevance to paediatric cancer, such as Horizon Europe, the Health Programme, the Clinical Trial Regulation, the Data Protection Regulation, the Cross-Border Healthcare Directive, and the Pediatric Regulation, among others.

MEPs also host our flagship annual International Childhood Cancer Awareness Day (ICCD2020) Event at the European Parliament (18 February 2020) to keep the visibility of paediatric cancer high on the EU policy agenda.

SIOP Europe anticipates highly pertinent EU policy developments in the next 5 years and we look forward to working with MEPs from across Europe to achieve our vision of Zero Deaths and Zero Late-Effects in line with the SIOP Europe and CCI Europe Manifesto.

Together with all our partners, including CCI Europe and PanCare, we are committed to working with the incoming European legislators to meet the challenges that greatly impact children and adolescent cancer patients and survivors’ lives.

A European paediatric cancer mission: aspiration or reality?*

The 2018 Mazzucato Report for the European Commission outlined a mission-oriented approach for the next EU Framework Programme for Research and Innovation. The recent confirmation that cancer will be the topic for the health mission area 2 is very welcome and we strongly believe this should include a mission to beat childhood cancers.

SIOP Europe celebrates wide support during Gold September: Childhood Cancer Awareness Month

SIOP Europe strives to raise awareness about childhood cancer all year round and especially in September as it is a special time in our community as we increase our efforts and activities to support children and young people with cancer.

We are delighted that 31 current Members of the European Parliament (MEPs) from 17 countries showed their support to the paediatric cancer cause, also by wearing the SIOP Europe Gold Ribbon pin and sharing their photo on Twitter using the hashtags #ChildhoodCancerAwarenessMonth #GoGold.

We continue to encourage other MEPs to support the Childhood Cancer Policy Priorities.


NEW: Clinical Training Centres – Paediatric Fellowship Programme

ESO and SIOP Europe have joined forces to offer a Paediatric Fellowship Programme for young paediatric haematologists and oncologists aiming to gain clinical experience at renowned centres across Europe.

The aim of the programme is to support the education of young and promising paediatric haematologist or oncologist to develop their careers in cancer care. The programme familiarises the trainees under supervision with all paediatric haemato-oncology disease types and instructs them in diagnostics and therapy. Successful applicants will be able to spend a defined period of time (3-6 months) at a centre of excellence in Europe where they will gain more knowledge in paediatric haemato-oncology and experience in a multi-disciplinary clinical setting specifically designed to address their needs. Currently, five centres are offering these paediatric oncology fellowships.
