Treatment duration of apatinib and OS
DISEASE PROGRESSION
In the current study, the median treatment duration of apatinib was 7.36 months, and the median duration of single apatinib maintenance therapy was 4.93 months. In the cohort, 15 patients used apatinib for less than 6 months, and 16 patients used it for more than 6 months. The difference in OS between the two groups of patients during the entire treatment process was statistically significant (6.34 vs. 18.10 months, Subgroup analysis of the OS of patients with different treatment characteristics. (A) Survival of patients treated with apatinib for different durations. (B) Survival of patients receiving chemotherapy after disease progression.
