Next-generation sequencing (NGS) is increasingly replacing single gene assays in the screening for therapeutic biomarkers in patients with NSCLC. While NGS has the clear advantage that it can detect all targetable oncogenic driver alterations simultaneously, this technique does come with the risk for a longer turnaround time, in part as a result of the centralized way in which this testing is often organized. However, with a delayed test result, you risk that some patients with a high disease burden miss the opportunity to be treated with a specific targeted therapy, or even die before the NGS result comes in. To mitigate this risk, it may be interesting to adopt a rapid PCR-based testing strategy for selected oncogenic driver mutations in parallel to broad NGS testing.

Antibody-drug conjugates (ADCs) combine the high specificity of monoclonal antibodies with the high anti-tumor activity of small molecular cytotoxic payloads. In 2013, the human epidermal growth factor receptor 2 (HER2)-targeted ADC ado-trastuzumab emtansine (T-DM1) entered the treatment arsenal for patients with metastatic breast cancer (BC), making it the first ADC to be approved for the treatment of a solid tumor. The pace of ADC development for solid tumors has since increased dramatically, with currently more than 100 ADCs being investigated in clinical trials. Specifically in breast cancer, there are now 3 EMA-approved ADCs: T-DM1, trastuzumab deruxtecan (T-DXd) and sacituzumab govitecan (SG). This article will briefly touch upon the key components and mode of action of ADCs after which the clinical experience with the EMA-approved ADCs in breast cancer will be discussed.

The Kirsten rat sarcoma viral oncogene homolog (KRAS) is mutated in about a quarter of all human cancers and is at the centre of several pathways involved in tumorigenesis. As such, novel therapeutic strategies that can target this oncoprotein are potentially extremely valuable. However, since its discovery as on oncogene, almost four decades have gone by without any major breakthrough in the therapeutic targeting of mutant KRAS. In recent years, however, we are finally witnessing a paradigm shift with the discovery of druggable pockets on KRAS and the clinical activity of covalent KRASG12C inhibitors such as sotorasib and adagrasib.

The breast cancer task force session of the Belgian Society of Medical Oncology (BSMO) annual meeting reviewed the most important recent data on advanced HER2-positive breast cancer and triple negative breast cancer (TNBC). First, Dr. Eline Naert (University Hospital Ghent) discussed the treatment algorithm for advanced HER2-positive breast cancer anno 2022. Prof. Francois Duhoux (UCLouvain) subsequently addressed the current and emergent treatment options for patients with early or locoregional advanced triple-negative breast cancer. Finally, Prof. Christos Sotiriou (Institut Jules Bordet) closed the session by further dissecting the TNBC heterogeneity through molecular profiling and special transcriptomics.

Next-Generation Sequencing (NGS) significantly changed cancer management, allowing the identification of different oncogenic drivers and the subsequent approval of many targeted agents. An overview of the Belgian reimbursement situation and drug access in this setting was given during the molecular tests in oncology session of the Belgian Society of Medical Oncology (BSMO) annual meeting. First, Prof. Brigitte Maes (Jessa Hospital, Hasselt) walked us through the current NGS situation in
Belgium with a discussion of the achievements and challenges of the BALLETT study. Subsequently, Dr. Kevin Punie (Leuven University Hospital, Leuven) discussed the current strategy, tasks and challenges of the molecular tumour board (MTB). Finally, Pr. Lore Decoster (University Hospital Brussel), Dr. Wim Demey (Klina General Hospital, Brasschaat) and Dr. Joëlle Collignon (CHU de Liège, Liège) addressed the reimbursements of drugs in lung, gastro-oesophageal, biliary and pancreatic cancer.

During the supportive care task force meeting, the BSMO supportive care task force introduced three clinical trials they would like to set up in the near future. In addition, new BSMO guidelines on extravasation and anaemia were presented after which the session was closed by Dr. Christel Fontaine (UZ Brussel) with a status update on the supportive care task force activities over the past year.

PACIFIC-R is a real-world international observational study evaluating patients with unresectable stage III non-small-cell-lung cancer treated with durvalumab following platinum-based chemoradiation. At the annual BSMO meeting, baseline characteristics and progression-free survival results for the Belgian cohort of this study were presented and contextualised with the PACIFIC-R global population and the durvalumab arm of the phase III PACIFIC trial.
