Trial summary

Pituitary adenomas, namely pituitary neuroendocrine tumors (PitNETs), are recognized as rare neoplasia by national and international institutions. Albeit most PitNETs are slow-growing with an indolent behavior, about one-third do not achieve biochemical control, recur, re-grow, and resist conventional treatments. Read more about this study

About this study

Official title: Clinical-pathological Assessment of Pit-NETs: Data From a Large Multicenter Patients Cohort

Pituitary adenomas, namely pituitary neuroendocrine tumors (PitNETs), are recognized as rare neoplasia by national and international institutions.

Albeit most PitNETs are slow-growing with an indolent behavior, about one-third do not achieve biochemical control, recur, re-grow, and resist conventional treatments.

The predictors of aggressive behavior have not been identified for PitNETs. In 2013 Trouillas and coworkers developed a five tiered clinicopathological score by mixing histopathological data and clinico-radiological evidence of invasion. This system proved of prognostic value. Nonetheless, unlike for NET of gut and lung, no formal grading and/or staging tools were developed. In addition, PitNETs have not been thoroughly investigated by radiomics to predict clinical behavior, nor have druggable pathways been elucidated in PitNET cells to unveil new potential therapeutic approaches.

The first aim of this project is to define grading and staging tools for PitNETs based on: i) lineage-specific transcription factors ; ii) cell type specification by hormone production (prolactin, TSH, LH, FSH, ACTH, GH or none); iii) integration of standard radiological measures with recognized tools for clinical and pathological staging.

The second aim of this project is to investigate radiomics features as predictors of PitNETs behavior, prognosis, and treatment outcome.

The third aim of this project is to investigate whether the expression of molecular biomarkers [Vascular Endothelial Growth Factor (VEGF), Epithelial Growth Factor Receptor (EGFR), somatostatin receptors 1-5 (SSTRs), Fibroblast Growth Factor (FGF), mTOR (mammalian target of rapamycin), Programmed cells Death 1 (PD1) and its ligands (PD-L1), and Cytotoxic T Lymphocyte Associated protein 4 (CTLA4)] may impact on patients prognosis. Identifying new molecular pathways may help fine-tune and schedule the emerging targeted therapies for aggressive PitNETs, including mTOR inhibitors, VEGF, EGFR, and immune check-point inhibitors.

This study will investigate a large multicenter retrospective series of 740 PitNET patients and a prospective cohort of 200 patients to reach these objectives.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • grading & stagingDiagnostic test

    To investigate the following pathological features of PitNET cell lineage-specific transcription factors, cell type specification by hormone production, proliferative index, p53, mitotic count, expression of somatostatin receptors

  • PitNET morphology analysisDiagnostic test

    Revision of the pre-surgical magnetic resonance images (MRIs): tumor maximum diameter, volume, sites of tumor extensions and invasion, and grading of cavernous sinus invasion

  • RadiomicsDiagnostic test

    To investigate radiomics features of PitNETs

  • Molecular test: proteomicsDiagnostic test

    To investigate on PitNets of molecular biomarkers Vascular Endothelial Growth Factor (VEGF), Epithelial Growth Factor Receptor (EGFR), somatostatin receptors 1-5 (SSTRs), Fibroblast Growth Factor (FGF), mTOR (mammalian target of rapamycin), Programmed cells Death 1 (PD1) and its ligands (PD-L1), and Cytotoxic T Lymphocyte Associated protein 4 (CTLA4)]

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Grating and staging

    To investigate the following pathological features of PitNET cell lineage-specific transcription factors, cell type specification by hormone production, proliferative index, p53, mitotic count, expression of somatostatin receptors, through immunohistochemistry analysis on formalin-fixed paraffin-embedded samples of PitNETs

    Measured: 2 years

Secondary outcomes (3)
  1. PitNET morphology analysis

    Identification of PitNET morphology features, as tumor maximum diameter, volume, sites of tumor extensions and invasion, and grading of cavernous sinus invasion though the revision of pre-surgical magnetic resonance images

    Measured: 2 years

  2. Radiomics

    Radiomics features will be extracted and computed using the different standardized methods and platforms for quantitative imaging analysis though different standardized methods and platforms for quantitative imaging analysis. Radiomics analysis will be realized after segmentations test-retest, to evaluate and quantify features\' reproducibility.

    Measured: 2 years

  3. Molecular test: proteomics

    To investigate on PitNets the expression of Vascular Endothelial Growth Factor (VEGF), Epithelial Growth Factor Receptor (EGFR), somatostatin receptors 1-5 (SSTRs), Fibroblast Growth Factor (FGF), mTOR (mammalian target of rapamycin), Programmed cells Death 1 (PD1) and its ligands (PD-L1), and Cytotoxic T Lymphocyte Associated protein 4 (CTLA4)] through proteomic analysis on formalin-fixed paraffin-embedded samples of PitNETs for patients retrospectively included and on frozen tissues for patients prospectively enrolled.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Pituitary and Cancer, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 23 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Guido Rindi (+390630154433, guido.rindi@policlinicogemelli.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Grating and staging (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2024.
