Abstract: Introduction: rearranged advanced NSCLC (ALK+ aNSCLC), real-world data on treatment patterns, prognostic factors, and survival in the era of contemporary therapy remain limited. Methods: We conducted a retrospective observational cohort study using deidentified patient, disease, and outcomes data from the AUstralasian thoRacic cancers lOngitudinal cohoRt study and biobAnk (AURORA; ACTRN12625000038493). Eligible patients were diagnosed with ALK+ aNSCLC between 2006 and 2025. Results: Of the 4776 patients with thoracic malignancies enrolled across eight sites (as of April 2025), 218 met the inclusion criteria-the largest reported Australian cohort of ALK+ aNSCLC. All patients were treated in academic centers. The median age was 55 years; 54% were female, 66% were never-smokers, and 41% had participated in a clinical trial. The median overall survival was 90.8 months (95% CI: 69.8-not reached). Nearly all patients (99%) received an ALK inhibitor; 83% in the first-line setting. Treatment sequences evolved over time. Most (68%) received at least two lines of therapy; 21% received 4 or more lines. Smoking status, age, and Eastern Cooperative Oncology Group Performance Status were prognostically associated with survival. Conclusion: This study highlights the remarkable survival achievable in the real-world setting for some patients with ALK+ aNSCLC, compared with historical cohorts. Several clinical factors associated with survival were identified. Larger studies are needed to investigate how treatment sequences may be optimized to further improve survival outcomes.
