They regulate somatotroph adenoma treatment responses to therapy with somatostatin receptor ligands (SRLs), mediated by soluble factors and cytokines. In this study, we assessed the effect of SRLs treatment on TICs. A retrospective and observational study was performed on acromegaly patients to compare the number of TICs in 75 patients na\u00efve to SRL before surgery and in 33 patients treated with SRL for at least 6 months before surgery. In SRLs\u2010naive patients at surgery, the CD68+\/CD8+ ratio was higher in invasive tumors (4.9, IQR: 14,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.028) than in non\u2010invasive tumors (4.3, IQR: 4.2) as well as in patients not responsive to post\u2010surgical\/adjuvant treatment with SRLs (7.5, IQR: 13,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.006) than those responsive to treatment (3.4, IQR: 3.2). In patients treated with SRLs before surgery, the number of CD68+ macrophages and the ratio CD68+\/CD8+ were lower in patients non\u2010responsive to post\u2010surgery\/adjuvant SRL treatment (CD68+: 48\/HPFs, IQR: 22.9,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.005; CD68+\/CD8+: 2.0, IQR: 3.6,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.05) than in responsive patients (CD68+: 80\/HFPs, IQR: 51, CD68+\/CD8+: 5, IQR: 5.6). Higher CD68+\/CD8+ ratio was an independent risk factor for post\u2010surgery SRL treatment resistance, only in patients na\u00efve to SRLs at surgery (OR: 4.3, 95% IC: 1.4\u201312.9,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.006).
