The primary end point was progression-free survival (PFS), secondary end points included duration of locoregional control (LRC), overall survival (OS), quality of life and safety. For metastatic lung cancer, LRC is the local control of metastatic lung tumor here.

Between February 1, 2015 and May 19, 2018, 433 adult patients with gastric adenocarcinoma, lung adenocarcinoma and lung squamous cell carcinoma, multiline chemotherapy failure and lack of standard treatment, received oral apatinib 250 mg daily at the Affiliated Hospital of Qingdao University. Histologically proven were identified retrospectively using the Clinical Research Information Systems (CRIS) database. All patients were with Karnofsky performance status ≥70% or an Eastern Cooperative Oncology Group performance status of 0 to 1, with stable hepatic, hematologic, and renal functions. Cardiac disease and hemorrhagic disease were excluded. All patients had pre-therapy chest computed tomography (CT) prior to apatinib treatment, and follow-up chest CT at least every 4 weeks. The primary end point was progression-free survival (PFS), secondary end points included duration of locoregional control (LRC), overall survival (OS), quality of life and safety. For metastatic lung cancer, LRC is the local control of metastatic lung tumor here. Other patient demographic and clinical data, including age, gender; stage of disease, apatinib administered inclusion and withdrawal date, adverse events, oncologic clinical response, comorbid conditions, and smoking history, were retrieved from the CRIS database.
