The multidisciplinary management of rectal cancer is an evolving field, and these guidelines seek to offer direction for treating this condition. A tailored treatment approach should be based on a multi-disciplinary tumour board discussion taking into account tumour staging, patient performance status, and expectations. Patients with node-negative T1 rectal cancer can be managed by a local excision. In patients with early rectal cancer, primary surgery is the standard-of-care. In some of these patients, an organ-sparing approach by long-course chemoradiotherapy can be an alternative. A total neoadjuvant therapy (TNT)-approach consisting of a combination of (chemo)radiotherapy and chemotherapy is preferred for locally advanced disease.

Advanced hepatocellular carcinoma, known for its dismal prognosis, is a disease that is challenging to treat. For almost a decade, sorafenib was the only available treatment. However, the last two to three years have witnessed a true revolution in systemic treatment options for this lethal disease. Several targeted therapies with mostly anti-angiogenic properties have been developed and immunotherapy has made its entrance into the field. Furthermore, a growing understanding of the molecular pathways involved in hepatocarcinogenesis and new insights in tumour-immunobiology have led to the development of rational combination therapies, showing very promising results in a myriad of ongoing clinical trials. Here we review the latest developments and discuss the main consequences for clinical practice.

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.

Gastric (including gastroesophageal junction) adenocarcinoma ranks top three in global cancer mortality. Between 4–30% of patients have human epidermal growth factor receptor 2 (HER2) driven disease, and targeting HER2 receptor signalling improved prospects in metastatic setting. HER2 status is assessed by immunohistochemistry and in situ hybridisation. However, determination and interpretation of HER2 status remains challenging due to intra- and intertumoral heterogeneity and lack of data on the biological relevant cut-off. Currently, only trastuzumab is approved for treatment of HER2 amplified advanced gastric cancer. The strength of HER2 amplification at baseline and after progression should be integrated in future prospective randomised trials. HER2 loss occurs predominantly in cases with initial moderate immunostaining for HER2 and can lead to clinical resistance to trastuzumab. We review the use of liquid biopsies as an alternative to traditional tissue biopsies to overcome heterogeneity and to allow monitoring the dynamics of the plasma HER2 status. We believe that early detection of plasma HER2 loss can identify patients at risk for loss of response to anti-HER2 therapy. Based on a clinical case, we tried to define the implications and clinical relevance of HER2 positivity. We illustrate the usefulness of re-determination of the HER2 status in metastatic lesions after disease progression and provide the prospects of non-invasive testing.

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.

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.
