The goal of this observational study is to create, manage and analyze a retro-prospective multicenter national database of patients diagnosed with multiple endocrine neoplasia type 1 (MEN1) syndrome (including genetic, clinical and/or familiar diagnosis), aimed at collecting and studying anamnestic, diagnostic, genetic, clinical, and therapeutic data in a relatively high number of patients with this rare inherited endocrine tumor syndrome in Italy.
The study will include 33 specialist clinical centers of endocrinology, pediatric endocrinology, pediatrics, and endocrine surgery, located throughout the Italian territory, and to which patients refer from all the 20 regions of Italy.
Data will be collected over time, both in retrospective and prospective manners, during the 10-year average duration of the study, starting from the recruiting visit (basal visit) and then during each follow-up visits patients will undergo for the control of disease at the recruiting clinical centers, allowing for an epidemiological evaluation of prevalence and incidence of MEN1 in Italy, collecting detailed clinical history of the disease in enrolled patients, and refining and deepening medical knowledge in the field of this rare inherited endocrine tumor syndrome, and, thus, to be able to define optimal tailored diagnostic, clinical, and therapeutic management of patients, improving their quality of life.
Collected data will include both the most classic traits of the pathology and the less common ones.
The main aspects this observational study aims to assess and clarify are:
1. Evaluation of prevalence and incidence of MEN1 in Italy. 2. Clinical characterization of MEN1 phenotypes, through both cross-sectional and longitudinal analyses of collected data, and also based on MEN1 mutation types and location. 3. Evaluation of the over time prevalence of bone mass loss, osteopenia, osteoporosis and fragility fractures in patients with MEN1, with and without primary hyperparathyroidism, globally and also based on gender and age. 4. Over time evaluation of responses to surgical and pharmacological therapies in in patients MEN1. 5. Evaluation of dietary habits in MEN1 patients, by filling out a specific questionnaire at the time of the study recruitment. 6. Evaluation of quality of life and accessibility to specialist medical centers and to surgical and pharmacological therapies on the Italian territory by patients affected by MEN1 syndrome, globally and according to the region of residence, by filling out a specific self-evaluation questionnaire at the time of the study recruitment.
The study will include a single cohort of female and male patients of any age, diagnosed with MEN1 syndrome (including either genetic, clinical and/or familiar diagnosis). The study does not include either any control group/comparison group or healthy volunteers.
The study itself does not involve any medical intervention or drug administration. Surgical and pharmacological treatments for which data on response to therapy will be collected in the database, are those commonly employed for the control/treatment of MEN1 tumors and related symptoms, regardless of patients' inclusion in this observational study.
