“…The underlying mechanism of delayed remission in acromegaly after TSS remains unclear. One possible hypothesis for delayed remission is that it takes longer than expected for IGF1 levels to return to normal (7). Another hypothesis is that there are still some residual GH-secreting tumor cells after pituitary adenoma resection.…”

“…According to the literature and our clinical experience, some patients with acromegaly do not reach the remission standard in the short term after surgery but achieve remission without additional postoperative treatment during long-term follow-up; this phenomenon is defined as postoperative delayed remission (5,6). Changes in GH and IGF1 levels may be inconsistent following surgery, and the reason for delayed remission may be a longer-than-expected period required for IGF1 levels to return to normal (7). The reason may also be that the residual tumor cells gradually necrotize with ischemia after surgery.…”

“…Finally, according to our definition of biochemical remission after surgery, we included several patients with normal GH and elevated IGF-1 levels in the remission group, which may have interfered with the results. Although IGF-1 may revert to the normal range after several months and show a delayed remission change [16,17,47], the PASQ scores in patients with discordant GH and IGF-1 levels in the short term after surgery are still unknown.…”

“…In fact, in comparison with GH, the decline in IGF1 is delayed due to the longer half-life of IGF-binding proteins. Nadir GH after an OGTT may slightly change over time, from immediately postoperatively to 3 months after NS [8]. A prospective study evaluated the predictive role of random GH and IGF1 on a postoperative day one and nadir GH following an OGTT 2 − 4 days after NS [9].…”
