Data links high doses of bone drug to cancer

A Medtronic product, when used in high doses during spinal fusion procedures, might increase patient cancer risks, according to data released Thursday at a national conference of spine surgeons.

The data had been given to the Food and Drug Administration by Medtronic when it sought approval to market a high-strength version of an existing bone growth product called Infuse. Based on those study findings, the F.D.A. rejected that higher-dose formulation, known as Amplify, citing concern about cancer risks.
