Changes in serum cytokines observed in the RFA-treated group. (A) levels of IL-6 were elevated early in the course of treatment and later returned to normal. (B) Levels of CXCL11 were elevated on day 14, which continued until the end of the study. (C) CXCL1 increased on day 14 and was then reduced on day 30. (D) CXCL5 rose on day 14 and remained elevated until day 30. The line in the middle of the box represents the median; the upper and lower ends of the box represent the first and third quartiles, respectively, excluding outlines. The upper and lower whiskers show the maximum and minimum scores, respectively. Individual dots represent individual patients’ values. Asterisks show the statistical significance.
