Background: Functioning (FCA) and silent corticotroph (SCA) pituitary adenomas act differently from a clinical perspective, despite both subtypes showing positive ACTH staining by immunohistochemistry. They are challenging to treat, the former due to functional ACTH production and consequently hypercortisolemia leading to Cushing disease, whereas the latter due to invasive and recurrent behaviour. Moreover, the molecular mechanisms behind their distinct behaviour are not clear...

Background: Non-functioning pituitary adenomas (NFPAs) necessitate prolonged clinical, biochemical and radiological observation, constituting a significant burden in terms of medical resources and societal costs. Reliable biomarkers associated with aggressiveness and recurrence of NFPAs are lacking. As the growth of tumor remnants is highly variable, molecular markers that can predict growth potential and tumor behavior are necessary.Aim: To identify tar...
