No agreed treatment once small cell #lungcancer comes back. Finding from RESONANCE, to be presented at #ESMO26 by @nicogirardcurie . 623 people with ext-stage #SCLC in France, Germany, Italy, Spain & UK. Once cancer returned, treatment varied widely. Authors point to a likely reason: there are too few effective options. This is Western Europe, with some of the best-resourced health systems on the continent. We know far less about what happens to people with SCLC across Central & Eastern Europe. #LCSM
