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.

RAS-testing in colorectal cancer: Belgian guidelines

BJMO - volume 9, issue 5, september 2015

There is an urgent need for predictive biomarkers in several cancers. In colorectal cancers, KRAS exon 2 mutation analyses were mandatory when considering anti-epidermal growth factor antibody therapy with agents such as cetuximab or panitumumab. However, since the introduction of this testing, a cohort of patients still did not appear to benefit from this therapy. Recently, additional testing for KRAS exon 3 and 4, and NRAS considerably improved the predictive power for therapy success. Therefore, an update of the Belgian guidelines for RAS testing was urgently needed.
