The purpose of this Phase II, Open-label, single arm, exploratory study is to evaluate the efficacy and the safety of Apatinib（500mg/d）for the second - line treatment of esophageal cancer or esophageal and gastric

This study is a prospective,single-center,single arm,Ⅱ exploratory study.To explore the clinical study of the efficacy and safety of the treatment of vegfr-2 high expression by apatinib mesilate.The main research object for first-line treatment failure Ⅲ/Ⅳ integration of a period of esophageal or gastric esophagus cancer patients.The main purpose of the study was to evaluate apatinib for the median PFS of the esophageal and esophageal gastric junction carcinoma of the esophagus with high expression of VEGFR-2. The objective of secondary research is to evaluate the safety of apatinib for second-line treatment of esophageal and esophageal gastric junction cancer Objective Response Rate (CR + PR) and median OS and explore the relationship between VEGFR-2 high expression and apatinib efficacy and related prognostic factors. Thirty patients were enrolled in the study group. The group was expected to be enrolled in the group for 24 months, followed by 6 months of follow-up and 6 months of data statistics. The drug regimen was a single drug apatinib 500mg qd Po.Please refer to the CRF table for details.
