Clinical-pathological Evaluation of Pit-NETs

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Observational

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT06607198
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
