NET-TIME: Inflammatory Tumor Microenvironment in Pituitary Neoplasm (NET-TIME)

May 14, 2026 updated by: Fondazione Policlinico Universitario Agostino Gemelli IRCCS

Inflammatory Tumor Microenvironment in Pituitary Neoplasm

Over the past twenty years, a progressively increasing number of markers biochemical, clinical, imaging, histopathological or genetic have been suggested to attempt to predict aggression and therapeutic outcome, both in secretory PitNETs and in non-secretory PitNETs. In recent years, the microenvironment tumor (TEM) has been extensively studied in different malignancies, promoting the development of therapies target and immunotherapy with checkpoint inhibitors immune system (ICI). Data on TIME in PitNETs are scarce today and derive from studies conducted mainly on heterogeneous cases for type of PitNET. Therefore, the purpose of this research project is to investigate the TIME in PitNET, to identify immune biomarkers and new molecular pathways that can promote the use of ICI and target therapies in Aggressive PitNETs.

Detailed Description

Pituitary adenomas are currently recognized such as pituitary neuroendocrine tumors (PitNETs), as originating from the neuroendocrine cells of the pituitary gland and represent about 10% of all intracranial tumors. Over the past twenty years, a progressively increasing number of markers biochemical, clinical, imaging, histopathological or genetic have been suggested to attempt to predict aggression and therapeutic outcome, both in secretory PitNETs and in non-secretory PitNETs, such as concentration blood tests of secreted hormones, the patient's gender, the age at onset of the disease, the size of the tumor, signs of local invasiveness, tumor indices of proliferation and mitotic indices. However, unique and reproducible markers of tumor aggressiveness and outcome have been identified therapeutic. In recent years, the microenvironment tumor (TEM) has been extensively studied in different malignancies, promoting the development of therapies target and immunotherapy with checkpoint inhibitors immune system (ICI). Data on TIME in PitNETs are scarce today and derive from studies conducted mainly on heterogeneous cases for type of PitNET. Plus most of the studies on TIME in PitNETs they were focused on study of the inflammatory cellular infiltrate and in particular on lymphocyte populations, showing a heterogeneous phenotype during the different phases of the natural history of neoplastic pathology. Therefore, the purpose of this research project is to investigate the TIME in PitNET, to identify immune biomarkers and new molecular pathways that can promote the use of ICI and target therapies in Aggressive PitNETs.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cells immune systems
Time Frame: 24 months
Quantify and locate cells immune systems (lymphocytes CD3, CD4, CD8, CD20, CD138, CD68+ macrophages) associated with the various PitNET subtypes in the study
24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Chemokines in PitNETS samples
Time Frame: 24 months
Identify cytokines and chemokines in PitNETS samples, through Human Cytokine antibody Array ab 133997
