Small-Cell Lung Cancer: Biology, Translational Science and Clinical Innovation
TL;DR
A broad overview of established multidisciplinary management of both limited-stage and extensive-stage SCLC is discussed to provide understanding of how the next decade is likely to bring significant clinical gains as emerging therapeutics seek to redefine the management of SCLC and build upon novel advances.
Abstract
Small-cell lung cancer (SCLC) is widely considered one of the most aggressive human malignancies, characterized by development of rapid metastases and eventual resistance to platinum chemotherapy and immunotherapy. For decades, despite rigorous scientific investigation and well-established mouse models providing a basis for mechanistic understanding, there were limited therapeutic advances for SCLC. The past decade has seen reinvigoration of drug development for SCLC as well as US Food and Drug Administration (FDA) approval of tarlatamab, a bispecific T-cell engager with unprecedented survival advantage in this recalcitrant disease. Multiple other promising clinical trials in the first and later-line settings are underway that seek to challenge standards of first-line chemoimmunotherapy, investigate combination treatments in the later line, and introduce T-cell engagers earlier in treatment. This review provides a comprehensive primer on the biology and molecular landscape of SCLC, in the context of how both shape ongoing investigational strategies. A broad overview of established multidisciplinary management of both limited-stage and extensive-stage SCLC is discussed to provide understanding of how the next decade is likely to bring significant clinical gains as emerging therapeutics seek to redefine the management of SCLC and build upon novel advances.
