History
Investigations using yttrium-90 (90Y, Y-90) and other radioisotopes for cancer treatment began in the 1960s. Reports of the initial use of resin particles of Y-90 in humans were published in the late 1970s. In the 1980s, the safety and feasibility of Y-90 microsphere therapy for liver cancer were validated in a canine model. Clinical trials of Y-90 applied to the liver continued throughout the late 1980s to the 1990s, establishing the safety of the therapy. More recently, larger trials and RCTs have demonstrated safety and efficacy of Y-90 therapy for the treatment of both primary and metastatic liver malignancies.

Famous quotes containing the word history:
“History does nothing; it does not possess immense riches, it does not fight battles. It is men, real, living, who do all this.... It is not “history” which uses men as a means of achieving—as if it were an individual person—its own ends. History is nothing but the activity of men in pursuit of their ends.”
—Karl Marx (1818–1883)
“History has neither the venerableness of antiquity, nor the freshness of the modern. It does as if it would go to the beginning of things, which natural history might with reason assume to do; but consider the Universal History, and then tell us,—when did burdock and plantain sprout first?”
—Henry David Thoreau (1817–1862)
“What you don’t understand is that it is possible to be an atheist, it is possible not to know if God exists or why He should, and yet to believe that man does not live in a state of nature but in history, and that history as we know it now began with Christ, it was founded by Him on the Gospels.”
—Boris Pasternak (1890–1960)
