Abstract
Small-cell lung cancer (SCLC) is a highly aggressive and rapidly proliferative malignancy that has historically had limited therapeutic advancements. Recent advancements in the understanding of SCLC have led to attempts at subtyping the disease based on transcription factor characteristics, offering new insights into its biology and potential therapeutic targets. In addition, significant progress has been made in developing treatment regimens, providing new hope for improved patient outcomes. The introduction of immune checkpoint inhibitors, such as atezolizumab and durvalumab, in combination with traditional chemotherapy, has marked a significant advancement, demonstrating improved overall survival and progression-free survival compared to chemotherapy alone. Despite these advancements, the prognosis for extensive-stage SCLC (ES-SCLC), the more advanced form of SCLC, remains poor, highlighting the critical need for ongoing research and the development of novel therapeutic strategies. New treatment modalities, such as lurbinectedin and anti-Delta-like Canonical Notch Ligand 3 antibodies, are now included in the treatment options for refractory SCLC, and many more treatment strategies involving combination therapies are being studied. Advances in molecular profiling and the identification of biomarkers are aiding in the development of personalized treatment approaches. This review focuses on these recent advancements and emerging strategies in the treatment of ES-SCLC.
