NCI Dictionary of Cancer Terms


tumor lysis syndrome  listen  (TOO-mer LY-sis SIN-drome)

  A condition that can occur after treatment of a fast-growing cancer, especially certain leukemias and lymphomas (cancers of the blood). As tumor cells die, they break apart and release their contents into the blood. This causes a change in certain chemicals in the blood, which may cause damage to organs, including the kidneys, heart, and liver.
