This study was a multicenter, prospective, non-interventional clinical study that included first-line and late-line patients with advanced non-small cell lung cancer with ALK fusions treated with the third generation ALK-TKI lorlatinib until disease progression, intolerable toxicity, investigator or subject decision to withdraw, lost to follow-up, initiation of other antineoplastic therapy, or death. Clinical pathology including sex, age, ALK mutation status at diagnosis, and clinical stage at diagnosis were collected from medical records. Physical condition as assessed by ECOG-PS before administration of lorlatinib was also recorded. Treatment information was obtained from the records, including dose and timing of ALK-TKI therapy and tumor response, number of prior systemic lines of therapy, and local treatment modalities such as radiotherapy and surgery. Quality of life based on the EORTC QLQ C30+LC29 scale (plus the EORTC QLQ BN20 scale in patients with brain/meningeal metastases) was performed at baseline and at each follow-up point. This study will use REDCap platform to collect and manage the study data information of multi-center patients.
