Genetic Bases of Neuroendocrine Neoplasms in Mexican Patients (NCT06523582)
🩺 Plain-English Summary (8th-Grade Level)
Neuroendocrine neoplasms (NENs) are a heterogeneous group of lesions derived from cells with the ability to produce hormones that may arise from multiple different organs. Their clinical behavior is quite variable, encompassing both benign lesions and aggressive tumors that invade surrounding and/or distant structures. NENs may also cause serious morbidity due to hormone oversecretion. NENs are among the most frequently inherited human tumors, presenting either isolated or as part of syndromes in which a single patient or family develops multiple tumors. There are also non-inherited changes in the genetic information of the tumor cells that are potential targets for treatment. Both inherited and non-inherited DNA defects can be identified using modern routine genetic tests which, unfortunately, are not widely available in Mexico. This project seeks to uncover the genetic defects causing NENs in a large cohort of Mexican patients, using three different methods for genetic testing. Adult individuals with various types of NENs from two reference hospitals in Mexico City will be invited to participate. After completing informed consent, blood and, if possible, tissue samples will be obtained from all participants. Clinical details, laboratory results, imaging studies, and histopathological data at disease presentation will be retrieved. An initial screening will be performed by analyzing changes in the sequence of multiple genes that have been associated with the occurrence of NENs. In cases with negative screening, a specific method to assess changes in the number of copies of the same genes will also be employed. Finally, sequences of all DNA regions encoding information required to make proteins will be obtained in selected cases. Analyses will be carried out in blood and, if available, also in tumor tissue samples from study participants. Screening of additional family members will be offered. This project will accurately describe the repertoire of specific defects causing NENs in the study population, and will likely uncover and characterize novel genetic associations. The results will contribute for a better understanding of the alterations within and outside known driver genes that shape syndromic presentations, tumor behaviors, and inheritance patterns in individuals with NENs. These data will contribute to improve the information on the molecular bases of NENs, including alterations that can be used as therapeutic targets.
