CHICAGO--(BUSINESS WIRE)--ASCO Abstract Number: 9004 - Cancer-related fatigue is often a major problem for cancer patients, beginning at diagnosis, during treatment and after completing therapy. Researchers at Mayo Clinic and the North Central Cancer Treatment Group (NCCTG) recently completed a study testing methylphenidate in the treatment of cancer-related fatigue and found that, while it did not improve fatigue for a broad group of patients, the data did not rule out a benefit for those with stage III/IV cancer. Results of this NCCTG study, N05C7, will be presented on Sunday, June 6, 2010, at the American Society of Clinical Oncology annual meeting in Chicago.
