Figure 4. Transition of tumor markers and abdominal circumference length.

(A) Carcinoembryonic antigen (CEA), (B) carbohydrate antigen 125 (CA125), (C) abdominal circumference. CEA decreased temporarily with the start of chemotherapy, but began to rise on the 37th day. During three rounds of NK cell therapy, CEA and abdominal circumference decreased. CA125 continued to rise during the first three doses of NK, but decreased rapidly after the third dose. Green areas indicate the duration of WT1-DC vaccine therapy. Gray zones indicate the duration of NK cell therapy. The dotted line is the date of NK cell administration.
