Overview
Small cell lung cancer (SCLC) is a fast-growing type of lung cancer, and most patients are diagnosed at an advanced, or “extensive-stage” (ES-SCLC), when treatment options are limited and relapses are common. This study used data from the Flatiron Health Panoramic database comprised of >29K patients with SCLC to identify a cohort of This study used data from the Flatiron Health Panoramic database comprised of >28K patients with SCLC to identify a cohort of over 13,000 adults in the US diagnosed with ES-SCLC between 2019 and 2024.
Researchers examined which treatments patients received over time, especially after their cancer returned or stopped responding to initial therapy. Nearly half of patients received only first-line therapy, and just over one in five received both first- and second-line treatments. Most started with platinum-based chemotherapy plus immunotherapy, but there was significant variation in the therapies used in later lines, including newer drugs like lurbinectedin and tarlatamab.
Why this matters
Despite new therapies, many people with ES-SCLC still have few effective options after their cancer returns. This research highlights the ongoing challenges and unmet needs for these patients, showing that most do not receive more than one or two lines of treatment and that there is no clear standard for later therapies. By mapping out real-world treatment patterns, this study helps identify where new treatments are most needed and can guide future research and drug development to improve outcomes for people facing this aggressive cancer
