Results: Among a total of 148 patients, 48 (32%) had mutated KRAS, 77% at codon 12 and 23% at codon 13. The PFS was significantly worse in the mutant KRAS patients in comparison to wild type KRAS patients (p < 0.05). The
[Paragraph-level] PMCID: PMC4378307 Section: ABSTRACT PassageIndex: 3
Evidence Type(s): Prognostic, Diagnostic
Justification: Prognostic: The passage indicates that KRAS mutation, specifically G12D, is associated with a poor prognosis in progression-free survival (PFS), demonstrating its role as an independent negative prognostic factor. Diagnostic: The mention of KRAS mutations, including G12D, being associated with specific outcomes in patients suggests that these mutations can be used to classify or define disease subtypes.
