Clinical characteristics: Patient age at primary treatment, histological subtype of epithelial ovarian carcinoma, FIGO 2014 stage, progression-free survival (PFS), engraftment time in immunodeficient mice and CD24 expression status of the original patient material and the corresponding PDX sample indicated as immunohistochemical staining index (SI). SI = CD24 staining intensity (0–3) x positive stained area (0–3); 0 = no expression, 9 = strong expression. PFS was defined as time in months from the first day of primary treatment to disease recurrence.
