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.
