BACKGROUND: One million people worldwide benefit from chronic dialysis, with an increased rate in Western countries of 5% yearly. Owing to increased incidence of cancer in dialyzed patients, the management of these patients is challenging for oncologists/nephrologists. PATIENTS AND METHODS: The CANcer and DialYsis (CANDY) retrospective multicenter study included patients under chronic dialysis who subsequently had a cancer (T0). Patients were followed up for 2 years after T0. Prescriptions of anticancer drugs were studied with regard to their renal dosage adjustment/dialysability. RESULTS: A total of 178 patients from 12 institutions were included. The mean time between initiation of dialysis and T0 was 30.8 months. Fifty patients had received anticancer drug treatment. Among them, 72% and 82% received at least one drug needing dosage and one drug to be administered after dialysis sessions, respectively. Chemotherapy was omitted or prematurely stopped in many cases where systemic treatment was indicated or was often not adequately prescribed. CONCLUSIONS: Survival in dialysis patients with incident cancer was poor. It is crucial to consider anticancer drug treatment in these patients as for non-dialysis patients and to use current available specific drug management recommendations in order to (i) adjust the dose and (ii) avoid premature elimination of the drug during dialysis sessions.
