AKI in the Critically Ill Cancer Patient

• Acute kidney injury (AKI) is common in the critically ill cancer patient and associated with worse outcomes.
• The incidence seems to be higher in patients with hematologic malignancies.
• Despite many different etiologies for AKI in cancer patients (tumor lysis syndrome, hypercalcemia, chemotherapeutic drugs, etc) the most common cause is sepsis, accounting for 58-65% of causes.
• Given the emphasis on early antibiotic administration in sepsis, be sure to double check the potential for nephrotoxicity of antibiotics for this patient population.  When possible, avoid nephrotoxic meds, such as aminoglycosides, that can worsen AKI.
