The incidence of tumors is increased in patients with chronic renal failure and even more in patients on dialysis. Dialysis can affect both therapy and prognosis of oncological patients. It increases both cancer-related and non-cancer-related mortality rates and is the main cause of a suboptimal use of therapies. In patients with renal impairment, the dosage of many chemotherapies should be reduced but, due to the lack of real knowledge of the pharmacokinetic and pharmacodynamic properties of these drugs in dialysis, dosage adjustments are often done empirically and most often avoided. Although many papers are available in the literature regarding chemotherapy in dialysis, there is a lack of consensus regarding drug dosages and administration schedules. Furthermore, guidelines are absent due to the lack of "evidence" for most of these patients, usually excluded from experimental treatments. Specific onconephrologic trials are therefore mandatory to decide how much, how, and when to use chemotherapy in patients on dialysis and thereby ensure adequate treatment for these patients.
