A Real-World Study in Advanced Non-Small Cell Lung Cancer with KRAS Mutations.

Background: KRAS gene mutations are well known as a key driver of advanced non-small cell lung cancer (NSCLC). The impact of KRAS-mutant subtypes on the survival benefit from salvage chemotherapy is controversial. Here, we present a real-world study in patients across China with advanced NSCLC with KRAS mutations using a website-based patient self-report system.
