The majority of acromegaly and gigantism are caused by growth hormone-secreting pituitary neuroendocrine tumors (PitNETs). Most cases can be cured or controlled by surgery, medical therapy, and/or radiotherapy. However, a few of these tumors are resistant to traditional therapy and always have a poor prognosis. The title aggressive/refractory is used to differentiate them from pituitary carcinomas. To date, there is no definitive conclusion on how to diagnose aggressive/refractory growth hormone-secreting PitNETs, which may have slowed the process of exploring new therapeutical strategies. We summarized the literature described diagnosis and treatment of the disease. Potential disease markers and prospective therapies were also included.

Background: Growth hormone-secreting pituitary adenomas (GHPA) display diverse biological behaviors and clinical outcomes, necessitating the identification of tumor heterogeneity and prognostically relevant markers.
Methods: In this study, we performed single-cell RNA sequencing (scRNA-seq) on 10 GHPA samples, four of which also underwent spatial transcriptome sequencing, and used scRNA-seq data from four normal pituitary samples as controls. Cell subtype characterization in GHPA was analyzed using multiple algorithms to identify malignant bias regulators, which were then validated using a clinical cohort.

The nature of somatotroph adenomas has not been clearly revealed in studies. We consider that there are macroscopic differences in intraoperative tumor consistency in acromegaly patients. We aimed to determine whether there is a relationship between intraoperative tumor consistency and histopathological subtypes by planning a prospective study to determine whether these differences are significant.

Immunohistochemistry (IHC) of somatostatin receptor subtype 2 can predict response to first-generation somatostatin receptor ligands (fg-SRLs) in acromegaly. Recently, we validated an open-source digital image analysis (DIA) to quantify somatostatin receptor subtype 2 (SSTR2) expression. We aimed to validate the DIA also on somatostatin receptor subtype 5 (SSTR5) in a new cohort of growth hormone (GH)-secreting pituitary tumors, with IHC performed in a different laboratory, and to correlate fg-SRL response with SSTs expression.

: In pituitary adenomas, examinations of surgical specimens have shown that dural invasion occurs in 42-85% of cases. No studies about dura mater invasion have been conducted specifically in acromegaly patients. The aim of the present study was to evaluate the relationship between histologically dural invasion and the main features of GH-secreting adenomas.

Hypothyroidism, a condition characterized by decreased synthesis and secretion of thyroid hormones, significantly impacts intellectual development and physical growth. Current treatments, including hormone replacement therapy and thyroid transplantation, have limitations due to issues like hormone dosage control and immune rejection. Tissue engineering presents a potential solution by combining cells and biomaterials to construct engineered thyroid tissue.
