We compared the immunoprofile of pituitary adenomas from Romania and Moldova. One hundred and eighty cases coming from Romania (94 cases, group 1) and Moldova (86 cases, group 2) were assessed by immunohistochemistry regarding all six basic hormones expressed in pituitary adenomas. Specific differences and similarities were found and stated for both groups. In group 1, 70% of cases were pituitary adenomas positive for one hormone, 13% were plurihormonal, while 17% were negative. In group 2, 50,3% of the cases expressed only one hormone and 12,5% were negative for all hormones. The highest difference was observed for plurihormonal adenomas, found in about 37,2% of cases for group 2 (2.86 times higher for group 2 compared with group 1). A higher incidence of GH-secreting adenomas characterized group "1," while group "2" had the highest percent of LH-secreting adenomas, 55% of cases being positive. Triple association was noticed in 4.25% of cases of group 1 and in 8,13% out of total cases, from group 2. Four-hormone association was found only in group 2, noticed in 15,56% of the cases. The present paper highlights strong evidences of a particular and different immunoprofile of pituitary adenomas coming from Romania and Moldova.

Gonadotroph neuroendocrine pituitary tumors are among the most common intracranial neoplasms. A notable proportion of these tumors is characterized by invasive growth which hampers the treatment results and worsens prognoses of patients. Increased hsa-miR-184 expression was observed in invasive as compared to non-invasive gonadotroph tumors.

Introduction: and research question: Prognostic factors to predict the behavior of pituitary neuroendocrine tumors (PitNET) are scarce. PD-L1 expression was associated with prognosis in other neuroendocrine neoplasms and we analyzed PD-L1 expression in PitNET, according to the 2022 WHO classification.

Material And Methods: A retrospective analysis was performed.

Purpose: A paradoxical increase in GH after oral glucose load (GH-Par) characterizes about one-third of acromegaly patients and is associated with a better response to first-generation somatostatin receptor ligands (fg-SRLs). Pasireotide is typically considered as a second-/third-line treatment. Here, we investigated the predictive role of GH-Par in pasireotide response and adverse event development.

Background: Endoscopic techniques allow for improved visualization and tumor debulking of pituitary adenomas. More thorough tumor resection, however, can be associated with higher rates of CSF leaks. We set out to determine if CSF leaks influenced patient perceived quality of life outcomes.
