Another expert said the finding echoes those seen in other studies involving cancer patients.
"Last year in a study published in the New England Journal of Medicine, Danish researchers studied 13 different cancers and found that in all types, the use of statins was associated with longer cancer specific survival," said Dr. Manish Vira, director of the fellowship program in urologic oncology at North Shore-LIJ's Arthur Smith Institute for Urology in Lake Success, N.Y.
But he stressed that the data so far come from observational trials, which can prove an association but not a cause-and-effect relationship between statin use and improved survival.
"Given the current data and known cardiovascular protective effects of statins, certainly it seems prudent to design clinical trials to study the potential of statin therapy in breast, colon, prostate and now kidney cancer treatment," Vira said.
Studies presented at medical meetings are typically considered preliminary until published in a peer-reviewed journal.
