SA, pretreatment with somatostatin analogues before surgery; DS, direct surgery group; GH, growth hormone; IGF-1, insulin-like growth factor 1; SSTR, somatostatin receptor. The Pearson correlation coefficient was used to analyze the correlations between the immunoreactive score (IRS) and clinical parameters.
