The fourth biennial IASLC Small Cell Lung Cancer Meeting will be held as a Worldwide Virtual Event in the Fall of 2021. The meeting will focus on preclinical and clinical advances in small cell lung cancer (SCLC) research, including, but not limited to, basic research on oncogenesis and biology of disease, preclinical therapeutic research, and highlights of ongoing clinical translation. From its inception, this meeting’s goals have been to provide a “state-of-the-state” update on recent progress in small cell lung cancer research, to establish a forward-looking perspective on key unanswered questions in the field, and to promote research collaboration among small cell lung cancer investigators. We hope that you will join us for #SCLC21. Additional meeting information will follow soon.
