ROCHESTER, Minnesota-Ibritumomab tiuxetan (Zevalin) significantly improves quality of life for patients with low-grade, follicular, or transformed non-Hodgkin’s lymphoma (NHL) patients, according to the results of a phase-III study reported by Gregory A. Wiseman, MD. "Low-grade lymphoma is not a curable disease, but patients live for a long time with it," said Dr. Wiseman, lead researcher and assistant professor, Radiology Department, at the Mayo Clinic in Rochester, Minnesota. "We want to know how patients are feeling, especially if they’re going through difficult treatments. What we discovered is that after receiving Zevalin, patients’ quality of life was good."
