# A Brief Overview of Molecular Biology in Pituitary Adenomas with a Focus on Aggressive Lesions

## TL;DR

This paper provides an overview of the molecular biology of pituitary tumors, focusing on aggressive forms and the need for better treatments.

## Contribution

The paper offers a concise summary of current understanding of molecular mechanisms in aggressive pituitary adenomas.

## Key findings

- Pituitary neuroendocrine tumors are heterogeneous and can exhibit aggressive behavior despite being classified as benign.
- Advancements in molecular biology are revealing genetic mutations linked to tumor development and progression.
- There is a growing need for tailored therapies due to increasing prevalence and limited treatment options.

## Abstract

Arising from the anterior lobe of the hypophysis, pituitary neuroendocrine tumors (PitNETs), previously known as pituitary adenomas, constitute an intricate and heterogeneous entity. Although they are defined as benign pathology, these tumors can often invade neighboring structures and demonstrate aggressive behavior. The continuous advancement of molecular biology has begun to shed light on the genetic mutations behind the development and evolution of this pathology, providing a better understanding. Notwithstanding, the rising occurrence in recent decades can mainly be attributed to advanced diagnostic techniques; however, these tumors continue to increase in prevalence and incidence, creating a heavy burden on healthcare systems. Consequently, the need for further studies is dire, primarily due to a lack of tailored therapeutic approaches. Thus, this article aims to offer a brief overview of the molecular biology behind these complex tumors to contribute, even on a small scale, to more comprehensive care.
