Methods: This is an open-label, prospective, observational study, pts (age ≥ 18 yrs) with pathologically or histologically diagnosed GC who were given apatinib treatment met the inclusion criteria. Results: From September 1, 2017 to September 1, 2018. 954 pts were enrolled. 679 pts received palliative treatment were included in the analysis. 499 (73.6%) were males. The age of the pts was (63.1 ± 10.8) yrs. Pts with ECOG PS 0/1 accounted for 78.1%.

There were 375 pts available for efficiency evaluation. Among them, 1 achieved CR, 35 achieved PR, 198 had SD, and 57 had PD, resulting in an ORR of 11.9% and a DCR of 77.4%. The mPFS is 4.2 m (95% CI: 3...
