In 2021, 1 in 3 cancers in the United States were diagnosed at a distant stage, and more than half of people with cancer go on to receive chemotherapy at some point. Even with that scale, outcomes hinge on regimen choices and timing, with platinum plus immunotherapy extending median overall survival for advanced lung cancer from 1.7 months to 5.2 months in pivotal trials. This post pulls together the real world burden and the trial level breakthroughs side by side, from hospitalization and costs tied to febrile neutropenia to the response rates that define modern standards.
