Immunotherapeutics, like immune checkpoint blockade (ICB), have demonstrated therapeutic efficacy in a variety of human cancers. Even among the tumour types described as responsive, immunotherapy is only efficient in a minority of the patients. To maximise therapeutic benefits, a biomarker to identify ICB-responders is needed. Tumour mutational burden would correlate with the efficacy of immune checkpoint inhibitors. Clinical evidence for TMB as biomarker already exists in metastatic melanoma, non-small cell lung cancer (NSCLC) and renal cell carcinoma (RCC). In this review an update about tumour mutational burden (TMB) is given.

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.

Under normal conditions, CD70, member of the tumour necrosis factor family, is only transiently expressed on activated T and B cells. Instead, constitutive expression of CD70 has been described on malignant cells in a range of solid and haematological malignancies. Through its receptor, CD27, the expression of CD70 can facilitate evasion of the immune system by three important mechanisms: induction of T cell apoptosis, T cell exhaustion and increasing the amount of suppressive regulatory T cells. The general aim of this thesis was to investigate the role of CD70 in solid tumour types and explore promising combination strategies for anti-CD70 therapy. Thereby, we focused on the role of CD70 in non-small cell lung cancer and colorectal cancer.

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.

In recent years, the outcome of patients with non-small cell lung cancer (NSCLC) has improved thanks to the development of targeted therapies. Currently, the introduction of immunotherapy for lung cancer patients offers new treatment opportunities. The pathologist is now asked to provide the most accurate possible diagnosis in association with theranostic information in order to provide the best therapeutic option. For immunotherapy, programmed death receptor ligand 1 (PD-L1) status is, at the present, the required biomarker for patient stratification, at least in first line treatment. Different international societies have already underlined the importance of guidelines for managing samples of non-small cell lung cancer NSCLC. With the goal of adapting these international recommendations to the Belgian landscape, Belgian guidelines were published in 2016. This update integrates immunotherapy into the previously published guidelines.

Targeted therapies have transformed the management of non–small-cell lung cancer and placed an increased emphasis on stratifying patients on the basis of the presence of oncogenic drivers. The best characterised molecular driver to date is epidermal growth factor receptor. Selective oral inhibitors of epidermal growth factor receptor that are superior to chemotherapy have become available in clinical practice. Unfortunately progression develops after a median of ten to twelve months. This article provides a framework for understanding clinically relevant resistance mechanisms to epidermal growth factor receptor-tyrosine kinase inhibitors and strategies to delay or overcome resistance, both those clinically available and those in development.

The treatment landscape for patients with advanced non-small cell lung cancer, who do not harbour an oncogenic driver abnormality, has changed dramatically over the last years. Second-generation antiangiogenic agents, such as nintedanib and ramucirumab, and particularly PD-1/PD-L1 inhibitors, such as nivolumab, pembrolizumab and atezolizumab have shown to prolong survival in pretreated non-small cell lung cancer patients. Immune checkpoint inhibition in the treatment of advanced non-small cell lung cancer comes with the promise of durable responses in responding patients. Nevertheless, one must appreciate that the average response rate seen with these PD-1/PD-L1 targeting agents is only about 20%. While PD-L1 testing may be used as an enrichment biomarker, a substantial proportion of patients still do not benefit from these agents. They could benefit from alternative therapeutic options, including novel anti-angiogenic agents. In this paper, a treatment algorithm is proposed that aims to optimise the second-line treatment choice for patients with lung adenocarcinoma, based on the available clinical data.
