Clinical characteristics and thyroid hormone dynamics of thyrotropin-secreting pituitary adenomas at a single institution
2021
Overview
PurposeThyrotropin-secreting pituitary adenomas (TSPA) are extremely rare pituitary adenomas; their perioperative thyroid hormone dynamics have not been completely elucidated. Here, we investigated the clinical characteristics, perioperative findings, and thyroid hormone dynamics of TSPA at a single institution.MethodsWe enrolled 11 patients who underwent transsphenoidal surgery (TSS) for TSPA during 2005–2019 at Hiroshima University Hospital (TSPA group) and 24 patients who underwent TSS for nonfunctioning pituitary adenomas (NFPA) in 2019 (NFPA group; for comparison). Their clinical characteristics, operative findings, and thyroid hormone dynamics, including serum thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4), were retrospectively analyzed.ResultsThe NFPA group demonstrated a slight temporary decrease in serum TSH/ FT3/ FT4 levels on day 1 postoperatively and improvement in the levels on day 4 postoperatively. In contrast, the serum TSH level in the TSPA group demonstrated a marked decrease on day 1 postoperatively but improved on day 7 postoperatively. The serum FT3 level was also markedly decreased on day 1 postoperatively but remained within the normal range. The serum FT4 level revealed a gradual decrease until day 21 postoperatively and then recovered within the normal range 3 months postoperatively. There was no significant difference in the frequency of decline in serum FT4 level between the two groups; no patients required thyroid hormonal replacement 3 months postoperatively.ConclusionsDespite a variable degree of transient hypothyroidism, all patients had a normal thyroid function after 3 months follow-up.
