The progressive improvement of the classification using modern analytical methods is an essential tool for development precise and personalized approaches to treatment pituitary adenomas. In recent years, endocrinologists have witnessed evolutionary changes that occurred in histopathological identification neoplasms, revealing new possibilities studying tumorigenesis predicting biological behavior.The paper considers historical aspects gradual adenomas, as well international 2022 WHO classification, according which adenomas are included list neuroendocrine tumors (PitNETs) reflect aggressiveness some non-metastatic characteristics adenoma presented, a histological subtypes aggressive gland, marked by main potentials invasive growth, increased risk recurrence negative clinical prognosis.The expediency changing definition «pituitary adenoma» «neuroendocrine tumor» discussed. It emphasized introduction unified clinical, laboratory morphological protocol into national practice will help provide comparable comparative studies on prognosis disease effectiveness secondary therapy also contribute adequate management potentially PitNETs.

Abstract Purpose The 14th Acromegaly Consensus Conference was convened to consider biochemical criteria for acromegaly diagnosis and evaluation of therapeutic efficacy. Methods Fifty-six experts from 16 countries reviewed discussed current evidence focused on assays; the role imaging, pathology, clinical assessments; consequences diagnostic delay; remission recommendations follow up; value assessment monitoring in defining disease progression, selecting appropriate treatments, maximizing patient outcomes. Results In a with typical features, insulin-like growth factor (IGF)-I > 1.3 times upper limit normal age confirms diagnosis. Random hormone (GH) measured after overnight fasting may be useful informing prognosis, but is not required For patients equivocal results, IGF-I measurements using same validated assay can repeated, oral glucose tolerance testing might also useful. Although primary treatment outcome, findings should interpreted within context acromegaly. Follow up assessments effectiveness, imaging studies evaluating residual/recurrent adenoma mass, signs symptoms acromegaly, its complications, comorbidities. Referral multidisciplinary pituitary center considered biochemical, or at diagnosis, insufficiently responsive standard approaches. Conclusion highlight new understandings disordered GH importance expert management this rare disease.

Pituitary neuroendocrine tumors (PitNETs) are one of the most common intracranial with diverse clinical manifestations. Current pathological classification systems rely primarily on histological hormone staining and transcription factors (TFs) expression. While effective in identifying three major lineages, molecular characteristics based hormones TFs lack sufficient resolution to fully capture complex tumor heterogeneity. Transcriptional diversity by alternative splicing (AS) offered additional insight address this challenge. Here, we perform bulk full-length single-cell RNA sequencing comprehensively investigate AS dysregulation across all PitNET lineages. We reveal pervasive dysregulations that better depict Additionally, delineate fundamental heterogeneity at resolution, confirming findings refining varying among cell types. Notably, effectively distinguish silent corticotroph subtype define a distinct TPIT lineage subtype, which is associated worse outcomes increased abnormalities driven altered ESRP1 In conclusion, our results characterize specific landscape PitNETs, enhancing understanding PitNETs subtyping. pituitary factors. authors analyze revealing subtypes abnormalities.

Aim: To investigate the predictor of hypothalamic-pituitary-gonadal (HPG) axis recovery in male pituitary adenoma patients with trans-sphenoid extrapseudocapsular microsurgery. Methods: From June 2019 to December 2021, we retrospectively analyzed clinical data gonadal hormone changes and resection degree before after surgery nonfunctioning (NFPA) who underwent microsurgical by pseudocapsule technique same treatment group at Department Neurosurgery, Tongji Hospital. We explored predictors affecting postoperative testosterone using logistics regression analysis. Results: Among 291 adenomas, mean age was 50 years. Preoperative lower than normal 127 (43.6%); total subtotal were performed 279 (95.9%) 12 (4.1%), respectively. Postoperative follicle-stimulating (FSH) elevated 224 (77.0%) patients, luteinizing (LH) 230 (79.0%) prolactin significantly decreased 259 (89.0%) patients. Seventy-one low preoperative levels recovered levels. Univariate multivariate analysis suggested that tumor size, coagulative necrotic apoplexy (CNPA), invasiveness (P < 0.05).

Pituitary neuroendocrine tumors (PITNETs) often show a tendency towards invasive behavior, i.e., an invasion the cavernous sinuses or destruction of sella turcica. In present study, we analyzed whether transcriptionally active HPV infection affects invasiveness pituitary tumors. Sixty patients with different phenotypes PITNETs who underwent neurosurgery were studied. The obtained postoperative material was histopathologically. For each patient, formalin-fixed paraffin-embedded blocks cut into ultra-thin slices and two to three them designated for DNA extraction, while one used histological slides.

Abstract Purpose This study evaluates the clinical presentation, endocrine dysfunction, surgical outcome, and long-term prognosis in patients with histologically confirmed posterior pituitary tumors (PPTs). Methods A retrospective cohort was conducted on 19 treated for PPTs at a single center between 2000 2023. Data clinical, endocrine, outcomes were collected analyzed. Results The included 3 pituicytomas (PCs), 8 granular cell (GCTs), spindle oncocytomas (SCOs) patients, female predominance (58%) mean age of 57.2 ± 13.2 years. Symptoms leading to diagnosis headache (31.6%), visual impairment (21%), sexual dysfunction (10.5%). GCT had higher preoperative BMI (34.49 5.72) compared PC (22.12 2.40) SCO (24.74 4.24) ( p < 0.01). Postoperative increased across all groups, GCTs showing steepest rise Endocrine largely persisted or worsened after surgery, limited recovery follow-up. Surgical approaches transsphenoidal (48%) transcranial (52%), achieving gross total resection 58% cases. Tumor recurrence occurred 16% requiring adjuvant radiation therapy. Tumor-specific survival 5 years 100% an overall rate 80% where non-tumor-related comorbidities accounted observed mortality. Conclusion are rare significant metabolic consequences. While management is associated favorable tumor-specific survival, persistent postoperative progressive underscore need follow-up targeted interventions. These findings contribute understanding PPT biology support development optimized strategies.
