Predictive, Prognostic evidence:
Predictive: The study reports that alectinib significantly improved progression-free survival (PFS) compared to crizotinib in treatment-naive ALK-positive non-small-cell lung cancer (NSCLC), indicating a correlation between the variant and response to therapy. The mention of "significantly prolonged investigator-assessed PFS" supports the predictive nature of the variant in relation to treatment outcomes.
Prognostic: The abstract discusses overall survival (OS) data, noting that the 5-year OS rate was higher with alectinib compared to crizotinib, which suggests that the variant correlates with disease outcome independent of therapy. The mention of "median OS was not reached with alectinib" further emphasizes the prognostic implications of the variant in this context.
