Predictive, Diagnostic evidence:
Predictive: The study indicates that ALK mutations may serve as a biomarker of response to lorlatinib, particularly in patients who have failed one or more second-generation ALK TKIs, suggesting a correlation between the presence of these mutations and treatment efficacy. The objective response rate was significantly higher in patients with ALK mutations compared to those without, demonstrating the predictive value of these mutations for treatment response.
Diagnostic: The study discusses the detection of ALK mutations in patients with ALK-positive non-small-cell lung cancer, indicating that these mutations can be identified through plasma and tissue genotyping. This suggests that ALK mutation status can be used to classify patients and potentially guide treatment decisions, fulfilling the criteria for diagnostic evidence.
