In the cured group, at the last follow-up (median time 86.8\u00a0months after surgery), only 1 patient (0.7%) showed full recurrence (IGF-1\u2009+\u20095.61 SDS, GH nadir 1.27\u00a0\u00b5g\/l), while 4 patients (3%) showed only increased IGF1. In the partially cured group at the last follow-up, 2\/8 (25%) patients showed active acromegaly (IGF-1 SDS\u2009+\u20092.75 and\u2009+\u20093.62; GH nadir 0.6 and 0.5\u00a0\u00b5g\/l, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In the literature, recurrence rates range widely, from 0 to 18%.
