Patients with KRAS mutations tend to have a poorer prognosis, and KRAS mutations have been identified as negative prognostic biomarkers. Patients with wild-type KRAS appear to have a shorter survival than those with KRAS mutations. However, KRAS mutational status is not predictive of a lack of chemotherapeutic efficacy.

A 2018 meta-analysis showed that EGFR mutations were significantly associated with improved OS and disease-free survival, whereas KRAS mutations predicted worse disease-free survival and OS in patients with resected NSCLC.
