Comparison of ex-miR-125b levels among the PR, SD and PD groups. (A) Ex-miR-125b levels at the treatment initiation point (baseline point) were compared among the groups. (B) Ex-miR-125b levels at the Response Evaluation Criteria in Solid Tumors judgment point after treatment (judgment point) were compared among the groups. Ex-miR-125b, exosomal microRNA-125b; PR, partial response; SD, stable disease; PD, progressive disease.
