Chronic kidney disease (CKD) and cancer are intertwined in many ways. In fact, cancer can cause CKD either directly or indirectly through the treatment adverse effects, while CKD may conversely be a risk factor for cancer. According to the Belgian Renal Insufficiency and Anticancer Medications (BIRMA) study, 64% of patients with cancer had a glomerular filtration rate (GFR) <90 ml/min/1.73m2 and 16% of them presented with a mildly to severely decreased GFR (i.e.; <30 ml/min/1.73m2 or 30–60 ml/min/1.73m2). As many anticancer drugs are predominantly excreted in the urine, tailoring the drug dose to the renal function of the individual patient is a crucial consideration. Furthermore, patients with cancer and CKD are also at an increased risk of thrombosis. Therefore, safe and effective drugs for the treatment and prevention of thrombotic events are necessary.

Primary bone tumours of the spine are relatively rare when compared to metastatic lesions and haematopoietic neoplasms. This often results in misdiagnosis leading to a high incidence of inadvertent intralesional surgery, which is associated in many cases with worse progression-free survival and overall survival. Based on evidence and consensus, a protocol was designed at the University Hospitals Leuven, intended to guide all possibly involved caregivers in different clinical situations. The protocol raises awareness of potentially suspicious situations and provides expert input to avoid unfortunate decisions, even in situations with alarming neurological deficits.

Randomised clinical trials are still the gold standard when it comes to the development of new drugs. There are, however, important limitations to trials. Such as, patients included in clinical trials are often not representative of the general population, which limits the applicability of trial results in clinical practice. In this article, the advantages and disadvantages of observational data are discussed. For example, observational data are generally more representative of the general population and can include large numbers of patients. However, there are important biases that should be considered when performing observational studies. Of these, so-called ‘confounding by indication’ is the most important form of bias, which means that reasons for certain treatment allocations are also associated with outcomes of treatment, which can disrupt the analyses. In summary, real-world data can add to clinical trials, but bias in these studies cannot be completely resolved. For this reason, clinical trials remain essential and should attempt to use less stringent inclusion criteria in order to improve the generalisability of their results.

Treatment of pancreatic ductal adenocarcinoma (PDAC) has been the subject of controversy for decades. At the centre of this controversy is radiation therapy. Since PDAC is considered a systemic disease, the role of radiation therapy is debated. However, most of the available evidence is blurred by suboptimal radiation doses, less effective chemotherapy regimens and abandoned radiotherapy techniques. This article reviewed the available literature and discussed the changes in radiation therapy that have taken place over the past decade.

Colorectal cancer is a prevalent cancer in Belgium. Unfortunately, many of these patients will develop metastases at some point in their disease. However, given the new therapeutic options, the prognosis of these patients is better than before. Local ablation of metastases is among these therapeutic options. This concept of metastasis-directed therapy (MDT) is generally accepted for oligometastatic disease. It can be accomplished by a multitude of techniques, including surgery, radiofrequency and microwave ablation, but also radiotherapy (RT). This review addressed the rationale and application of RT within this context.

Neoadjuvant treatments in patients with breast cancer provide the opportunity for a direct evaluation of treatment effect on tumour size, allow higher rates of conservative surgery and give the chance to tailor systemic treatments after surgery. Patients who achieve a pathological complete response experience better long-term survival, compared to those with residual disease after the completion of neoadjuvant therapy, and those with residual invasive disease at surgery may benefit from additional post-neoadjuvant treatment strategies. Some systemic post-neoadjuvant treatments for patients with residual disease at surgery are already approved in clinical practice (i.e., capecitabine for patients with triple-negative breast cancer, or T-DM1 for patients with HER2-positive disease), and several new strategies are currently under evaluation. The present review discusses the available evidence for the implementation of systemic post-neoadjuvant treatment strategies into clinical practice for patients with early breast cancer, shading light on the pitfalls and limitations of different studies, and summarising data on novel promising treatment strategies that are being explored in clinical trials.

Sarcopenia is defined as the loss of muscle mass and strength and plays an increasingly important role in the management of oncology patients. Sarcopenia is frequently mislabelled as malnutrition or cachexia. Clinicians lack a consensus definition of easy-to-use, straightforward, reliable diagnostic tools to optimally recognise sarcopenia. This review will broadly go through the current literature in order to define sarcopenia, as well as to understand its mechanisms. Helpful diagnostic tools will be discussed, which can be used to optimise the management of patients suffering from a malignant disease. This review will also illustrate how sarcopenia is an independent negative predictive and prognostic factor regarding survival and quality of life, directly impacting toxicity and efficacy of oncological treatments.
