Sichuan Cancer Hospital and Research Institute28 enrolled

Overview

This study was a retrospective observational study. The study included patients with non-small cell lung cancer with ALK-fusion brain metastases or meningeal metastases who received first-line and late-line treatment with the third-generation ALK TKI lorlatinib between June 2022 and June 2023. Data were collected from the electronic medical records database and hospital information system of many hospitals in Sichuan Province. Clinical pathology features including gender, age, ALK mutation status at diagnosis, and clinical stage at diagnosis were collected from the medical records. The physical condition assessed by ECOG-PS before the administration of lorlatinib was recorded. Information on anti-tumor therapy was obtained from the records, including dose and time of ALK-TKI therapy and tumor response, number of prior systemic therapy lines, drug regimen, efficacy, and whether local therapy such as radiotherapy and surgery had been received. In this study, the sample size is not limited, and information is collected according to the maximum number of patients. The study period was from 01 July 2023 to 30 June 2024.
