Safety of rituximab in a patient with chronic renal failure and low-grade non-Hodgkin lymphoma.

An 82-year-old man, with known chronic renal failure and a creatinine clearance (CrCl) of 18 mL/min, was diagnosed with low-grade marginal zone non-Hodgkinlymphoma (NHL) of his right orbit. He received rituximab as single treatment (375 mg/m 2 every 3 weeks). After eight cycles, almost complete response was obtained, rituximab was extremely well-tolerated, and his creatinine levels remained stable throughout the whole treatment.
