SUMMARY

In order to advise the Federal Government on the reimbursement of molecular tests related to Personalised Medicine in Oncology, the Commission of Personalised Medicine (ComPerMed), represented by Belgian experts, has developed a methodology to classify molecular testing in oncology. The different molecular tests per cancer type are represented in algorithms and are annotated with a test level reflecting their relevance based on current guidelines, drug approvals and clinical data. The molecular tests are documented with recent literature, guidelines and a brief technical description. This methodology was applied on different solid tumours for which molecular testing is a clear clinical need.

SUMMARY

In order to advise the Federal Government on all matters related to personalised medicine in oncology, including the reimbursement of molecular tests, the Commission of Personalized Medicine (ComPerMed) has applied, for the breast tumours, the same methodology as previously applied for the digestive tumours. Meaning, the different molecular tests, represented in the shape of algorithms, are annotated with test levels — which aim to reflect their relevance based on current available data and to define the reimbursement — and are documented with recent literature, guidelines and a brief technical description.

The Belgian Commission of Personalized Medicine has been created to advise the federal government on all matters related to personalised medicine in oncology, including the reimbursement of molecular tests. Here, we propose the Belgian strategy for molecular testing in the digestive tumours within a scientific-based framework. For each tested biomarker, a clinical test level is attached, which is key to establish the relevance of the test and to define the reimbursement. For each digestive tumour type, the different molecular tests are represented as decision trees with its test utility, test level and a brief technical test description.

Opportunities and challenges in oncology and molecular testing: the Belgian strategy

BJMO - volume 12, issue 2, march 2018

Summary

Molecular diagnostics in cancer aiming at improving diagnosis, prognosis and treatment are constantly exposed to new opportunities and challenges. The Belgian Commission of Personalised Medicine (ComPer-Med) has been created to advise the Federal Government on all matters related to personalised medicine in oncology, including the reimbursement of molecular tests. Here, we propose the Belgian strategy for molecular testing within a scientific based framework and its implementation in the Belgian healthcare system. For each tested biomarker a clinical test level is attached, which is key to establish the relevance of the test and to define the reimbursement.

The Belgian next generation sequencing guidelines for haematological and solid tumours

BJMO - volume 11, issue 2, march 2017

Van den Bulcke PhD

SUMMARY

Targeted next generation sequencing is a complex procedure including the ‘wet bench’ and ‘dry bench’ parts. Both parts are composed of many steps for which optimal assay conditions and settings must be determined.

The aim of these guidelines is to provide generic, platform independent, recommendations for targeted next generation sequencing tests to detect acquired somatic mutations in DNA, in (haemato)-oncology that are complementary to the ISO 15189 norm (medical laboratories) in order to:

  1. facilitate the implementation of the required quality metrics for the detection of somatic variants by next generation sequencing in oncology and haemato-oncology in the Belgian laboratories,
  2. harmonise test validation and verification,
  3. harmonise clinical interpretation and reporting of variants and,
  4. assure and maintain optimal test performance by establishing procedures and modalities for internal quality control and external quality assessments.

State of the art: gene expression profiles in early breast cancer

BJMO - volume 10, issue 4, july 2016

Summary

Gene expression profiles provide strong prognostic information and can predict breast cancer outcome mainly in women with lymph node-negative, oestrogen receptor-positive, human epidermal growth factor receptor 2-negative breast cancer. They are primarily designed to enable a more precise assessment on whether or not a patient needs adjuvant chemotherapy. However, the optimal use in clinical practice is still not established. The first set of data published from the TAILORx study and the results from the MINDACT study provide strong evidence for the clinical utility of gene expression profiles. Full disclosure of the results of prospective studies such as MINDACT and TAILORx on this topic is awaited in order to define their exact place in clinical decision-making. However, in several countries, these tests are already used in daily clinical practice, and are reimbursed. In addition, the use of gene expression profiles as a potential ancillary tool for treatment decisions is supported in several international treatment guidelines. Multiple studies have shown that there is a change in treatment decision based on gene expression profiles. In addition, different assays may provide different risk stratification at short-, middle- and long-term, so thoughtful use of these tests is recommended. Patients should be well informed about the benefits, risks, costs and uncertainties associated with these tests. Clinicians should also be educated on these matters. Furthermore, as gene expression profiles are expensive and not reimbursed in many countries, these tests are not accessible to all breast cancer patients. Patients’ preferences are important when making risk assessments and treatment decisions in those cases where there is doubt on the benefit of giving adjuvant chemotherapy. Taken together, gene expression profiles provide information that may be complementary to that provided by standard clinicopathological assessment in guiding decision of therapy in the adjuvant setting. These assays represent a step forward towards personalised medicine. We strongly propose to allow reimbursement of gene expression profiles in Belgium, but pragmatic and clear criteria for reimbursement should be developed with all stakeholders to avoid overconsumption.
