Prophylactic Antibiotic Regimens in Tumor Surgery (PARITY)

Summary

The Prophylactic Antibiotic Regimens in Tumor Surgery (PARITY) trial is the first ever international multi-center randomized controlled trial in bone cancer surgery. In order to avoid amputation for bone cancer in the leg, complex limb-saving operations are performed. However, infections with devastating complications following surgery are common. Surgeons from across the world will randomize patients to receive either short- or long-duration antibiotic regimens after surgery with the goal of identifying the best regimen to reduce these infections.
